Important
All persons, who mount, use, maintain or repair this machine, must
read these instructions to avoid
accidents.
See the safety instructions in particular.

Handbooks
This operator handbook is intended
as a general guidance to the operator of the Kongskilde Grain Drier
and describes the functions incorporated in the drier to assist the
operator in operating it efficiently.
The handbook does not form a
complete instruction of grain drying
and grain drying techniques. Before
attempting to use any high temperature grain drier, it is recommended
that operator knowledge is acquired in all aspects of grain biology, drier usage and storage techniques etc.
Books and magazines are published on the subject and these will
doubtless be available from local
libraries etc.
This operator handbook forms part
of the documents, which should be
in the operator’s hand, the others
being the installation manual and
the burner manufacturer’s handbook. These should all be gathered
together and kept accessible to the
operator, since all publications
contain information, which will be of
assistance to the operator. The full
range of handbooks should be
considered as an integral part of
the drier.
Kongskilde recommends that the
included instructions regarding
daily maintenance and fire prevention are displayed close to the drier.

Please note that whilst Kongskilde
equipment is of a considerably
standardised design, many machines incorporate variations to suit
specific requirements, and the company policy of continued improvement of their products necessarily
means that this publication cannot
be offered as being specific to any
particular machine, and should be
used for general guidance to the
principles involved only.
The information contained in
these publications is for general
guidance only. Kongskilde cannot accept liability for damage or
costs, which may arise in consequence of using this information.
If in any doubt on the correct
use, reference must be made to
the company for further information concerning the actual machine in question.

Introduction
KCD Continuous Flow Drier with
transverse laterals in the drying
column. – An ideal principle for
drying many different crops quickly
and economically in one continuous
operation.
During normal operation grain is
passing the drying column in a
vertical zig-zag movement. The
buffer section on top of the drier
secures a steady flow to the upper
drying sections, where hot air dries
the grain. The lower sections of the
column are used to let ambient air
cool the grain. At the bottom of the
column a discharger secure a uniform flow across the whole section
of the drier.
- The dry and cool grain is then
directed to the storage facility.
The KCD Grain Drier is an extremely efficient and reliable unit designed to use the most up-to-date

developments of drying technique
and manufactured to provide high
performance drying with low energy
consumption and simple troublefree operation. The drier, which is
designed for manual operation,
requires minimum supervision and
is designed to provide easy access
and fast, simple clean-out facilities
for daily cleanliness and when
changing crops.
Optimum performance can only be
achieved if the drier is correctly set,
operated and maintained relative to
the particular product being handled. The installation should ensure
that there are no restrictions to free
airflow to either of the air inlet or
outlet. Care should be taken in
installation to ensure that damp
drying air and any chaff etc. exhausted cannot be re-circulated
into the heater and air inlets of the
drier.
The drier should always be operated with a free, plentiful supply of
crop, so that the level of the crop
within the drier is never allowed to
fall below the safe level to expose
any laterals, and the crop being
discharged from the drier must be
allowed to discharge freely and not
cause any restriction to the crop
flow.
The purpose of this booklet is to
illustrate the various settings and
techniques that should be employed to obtain optimum performance.
The drier has been designed for
both commercial and farm drying
application. It is suitable for feed
grain, malting barley, seed grain, oil
seed rape and numerous other
similar commodities and is engineered to a high standard to ensure
a long efficient life, which can be
maximised by regular cleaning and
maintenance.

Safety
1: The Kongskilde continuous drier
is solely designed for drying of
grain and granular products.
The drier must not be used for
material with a higher bulk density than 900 kg/m3.
2: Appropriate use also implies
that all directions for mounting,
operation and maintenance are
followed.
3: The drier only has to be
mounted, maintained and repaired by persons, who are very
familiar with the working of the

drier and who are informed
about the risks of accident.
4: Follow the current directions for
prevention of accidents and
other general regulations for
workers by mounting, operation
and maintenance. A dust mask
must be used as protection
against dust and eventual mould
fungus when cleaning the drier.

6: Safety precautions for auxiliary
equipment:
Conveying equipment and other
ancillary equipment must be
supported in a safe way. This
load should not be supported by
the drier without approval by
Kongskilde.

5: By inadmissible changes on the
drier, the producer refuses to
accept any responsibility for any
damage caused hereby.

Prevention
Fire within a high temperature grain
drier is unfortunately not unusual,
but can almost invariably be eliminated with adequate cleaning and
maintenance, and the following
points should always be observed:

Do not attempt to run the fans in
order to cool the drier. This can
only increase the fire hazard.

1. The drier should be thoroughly
cleaned daily, that is in the hot
air plenum, the cooling air plenum, the exhaust plenum and in
all the inlet and exhaust laterals.
2. Observation of the grain and
grain flow should be maintained
regularly in order to detect and
clean any accumulations in all
the inlet and exhaust laterals.
3. Upon drying of grain with a large
content of impurities, the drier
should be inspected regularly
when empty in order to secure
that all impurities have been
removed, before drying continues.
4. Pre-cleaning the crop, before
entering the drier, is a reasonable and efficient technique for
minimising fire harzard within
the drier itself.
5. Regular and careful attention to
the suggestions under “Safety
and Cleaning” of this manual
must be observed.
6. Observation of the drier should
be maintained regularly to detect any indications of fire (smoke, smell changes etc.)
Precautions in case of fire
Should smoke be observed at any
time issuing from the exhaust fan of
the drier, it must be considered as
an imminent fire danger, and the
drier should be stopped immediately by pressing the STOP-button on
the control panel, or any other re-

Once the drier is stopped, the appropriate fire authority is called in
as a matter of urgency to deal with
the fire.

than this, then the fire authority with
their knowledge and experience will
be the best people to decide how to
deal with the fire.
Important Note
These notes regarding dealing
with a fire are given as guidance
suggestions only. All actions
should always be referred to the
fire authority and their advice
must be followed at all times.

Tel. no. is: _________
IMPORTANT!
Personnel should be evacuated
from the drier area and no action
should be taken, which could put
the safety of personnel at risk.
If the fire within the drier is only
small (frequently a quite dramatic
show of smoke will occur by a relatively small smouldering pocket of
impurities), then, under control of
the appropriate fire authority, it may
be practical to empty the drier of
crop as quickly as possible, ensuring that this discharged crop is put
to a safe concrete floor area, where
it cannot set fire to any surrounding
structure or materials.
Once the drier is empty, the fire
authority will be able to deal with
any smouldering pockets, which
are left within the drier.
After even a small fire, the drier
must be cleaned completely, and
any trace of fire within the discharged crop must be extinguished
and cooled before any attempt is
made to restart the drier.
Even a small fire can give off toxic
waste, which can overcome an
unprotected person within the drier,
and we strongly advise against any
operator entering the drier. Controlling the fire should be left to the
appropriate fire authority.
The above notes refer strictly to
small smouldering pockets of fire. If
the fire has taken a greater hold

Safety and Cleaning
Daily cleaning and inspection of the
drier is recommended upon use,
with special attention to the following points:
Hot air inlets:
Clean remaining impurities, which
are accumulated in air boxes.
Air outlets:
Inspect and clean air box to exhaust air for all accumulated impurities.
Air laterals:
Inspect the internal part of all air
laterals, both in the inlet and outlet
side.
Heaters:
Control and adjust any kind of fuel
waste and clean any dust etc. Control that the flames are clean,
shaped properly and smokeless (in
cases of doubt call in a technician).
Air inlets:
Keep all air inlets (to the heater,
cooling section etc.) clean and
avoid access of paper, straw, plastic, chaff etc.
Oil-seeds:
This type of seed has a highly inflammable content and can leave a
membrane of oil on the internal
side of the drier, which can build-up
places of waste, which should be
cleaned.

6

Inspection and cleaning are necessary in order to observe the safety
and efficiency of grain drying, with
special attention to drying of oilbearing seed.

Only qualified personnel should
operate this drier, and only when
instructions and safety precautions in this operation manual
have been understood and followed carefully.

Installation
Instructions:

Connection to hot air heater
The drier must only be connected
to a heater in accordance with
recommendation and requirements
from the public authorities.

- Please see the separate Kongskilde mounting instructions and spare
part list for the drying column.
Installation
The drier must be installed on an
even floor of reinforced concrete.
Level difference max 3 mm.
The floor must be dimensioned
regarding the weight of the drier,
when it is filled with grain, and the
structure of the ground - Please
see sketch of foundations enclosed
to the mounting instructions.
Always follow the current regulations and other general regulations for workers when mounting
to prevent accidents.
Every bolt/screw in the drier is
important for the strength of the
drier. Tighten all bolts/screws
carefully and control that none
are missing!

Description of
Components:
Legs:
Normal free height to floor 500 mm.
- Can be delivered to suit local
conditions.

The heater must be installed in
accordance with the current regulations from the local fire authorities.
The hot air channel between heater
and drier must be supplied with an
inspection door, so it can be
cleaned on the inside.
In some countries a fire hatch with
micro switch is mandatory in the
connection between heater and
drier.
Before installation contact the local
authorities regarding rules and
regulations for fire protection, building design, fuel supply and chimney
details.
Electricity
The design of the control system
1: An authorised company and
electrician must make the design and mounting of the electrical installation.

2: The electric cables must be
placed to avoid damages of the
isolation. Mechanical safeguard
must be used if necessary. Steel
belted cables are recommended
to avoid damage by rodents.
3: Electric control panel with
switching equipment should be
placed in an operating room,
separated from localisations
with grain, feed and dust.
4: The control system must be
supplied with a lockable main
switch.
5: The control system must be
designed, so that the drier has
to be started manually after a
power failure situation.
6: The heater and grain conveyors
must be stopped with a common
emergency shutdown, which
must be placed near drier and
elevator.
7: The heater must not be supplied
with a delayed blower stop in
emergency situations.

Has sq. outlet slide gate. Optional
transition to OK200.
Alternative hopper:
In order to reduce drier height the
standard hopper can be substituted
by a concrete pit/hopper in the floor
with build-in conveyor.

Bottom Hopper:
Hopper is 1455 mm high.
Has a large inspection door for
clean-up, service and repair.

Drying column:
Drying sections are 2880 x 1920
mm inside and 535 mm high. The
laterals are sitting in a close pattern
and have a large cross area with a
tapered form. The design gives
plenty of drying air at a moderate
airspeed, resulting in less problems
with build up of dirt in laterals and
therefore a very uniform drying.

Dischargers:
The discharger section is divided
into small hoppers under the gap
between the lower laterals in the
drying section above the discharger.
Small triangular transverse laterals
are placed in the hoppers to take
away the grain load from the hopper outlets and to make inspection
of discharger function possible.
Through inspection doors to the
small laterals, it is possible to remove eventual foreign matters
getting stuck in the discharger.

the slotted outlet of the hopper is
left fully open and grain flows out.
This secures an outflow of grain in
pulses according to the opening
sequence, - evenly across the
whole drying column.
The swing gates open and close in
one operation and the recirculating
throughput capacity of the drier is
regulated by changing the pause
time between the openings. When
the drier is going to be emptied the
swing gates can be kept open for
full capacity discharge.

Under each slotted hopper outlet a
swing gate is placed. When the
swing gate is moved to the side,

Top layer of laterals in the drying
sections is for in-going hot air. Half
laterals are for hot air, preventing
condensation and build up of dirt
inside half channels when drying in
cool weather.

If more than 2 buffer sections are
fitted, top layer of laterals in top
drying section must be fitted with

reinforcement profiles to take up
the higher grain pressure.

Transverse laterals are bolted outside grain bed to give smooth surface with no hiding pockets.
The lower sections are normally
assigned for cooling the grain with
natural air.

Drying section

Buffer section:
The buffer sections are 2880 x
1920 mm inside and 535 mm high.
Grain shrinks during drying. Buffer
section must be large enough to let
grain sink down into drying sections
and prevent laterals to be left open
leaking drying air.
To fill up the buffer - especially the
corners are difficult to reach, the
filling point must be 535 mm above
the edge of the buffer.
A ridged roof are supplied and form
part of the buffer.
A ladder/platform system to reach
the buffer/drier top is preferable. –
Optional extra.
Hot air plenum:
KCD has a 500 mm wide air plenum giving plenty of room for an
even distribution of drying air. Large
driers sometimes will have a plenum extention to give even better
air distribution. The wide plenum
also makes internal inspection
possible.

Roof of hot air plenum has inspection door for visual inspection of
plenum.
For optimum drying of crops with
various moisture contents one or
more air gates can be supplied to
change proportion of drier to be
used for drying.

Wet air plenum:
To collect and make it possible to
get wet and dusty air out of the
building, a wet air plenum is standard. The 500 mm wide air plenum
is giving plenty of room for an even
pick up of wet air. Large driers
sometimes have a plenum extention to give even better air distribution. The wide plenum also makes
internal inspection possible via the
lower inspection door.
Roof of wet air plenum has inspection door for visual inspection of
plenum.

An extraction fan is normally attached the wet air plenum to pull air
through the hot air drying sections
as well as natural air through the
cooling sections.
With wet air ducting longer than 8
m a stronger axial fan must be
added on the wet air side.

Blower/heat source:
A blower is required to suck air
through the drier. It is normally one
or more axial fan(s). The fan can be
supplied with a silencer to reduce
noise pollution.
For larger indirect heaters, a line of
KS heaters has been developed.
In some countries a fire hatch with
micro switch is mandatory in the
connection between heater and
drier.

The importance of pre-cleaning. A careful pre-cleaning results in:

perature reduces the germination
capacity of grain and has an influence on the baking qualities of
bread grain. In cases of doubt,
discuss this with the company buying the dried grain.

Lower energy consumption, due to
a reduced consumption of heat and
electricity for drying impurities.
Higher drying capacity, as drying air
penetrates grain more easily.
Less cleaning and maintenance
work, as the drier and environment
are more clean.
Less fire risk, as the drier and environment are more clean.

A temperature of 80-90°C can normally be used for drying crops for
feed grain. Drying air temperatures
of 55-65°C are normally considered
safe for drying of crops for seed
and malt.
Other crops than grain require
considerable lower hot air temperatures in order not to damage the
crop during drying.

Adjustment of airflow:
The KCD drier normally works with
a negative pressure. Discharge air
can be conducted away through a
large dimensioned discharge pipe.
If the length exceeds approx. 8 m,
a more powerful blower than standard should be used.

As grain is a biological product with
different resistance to temperatures, fungi attacks, mechanical
damages etc., the above-mentioned drying air temperatures are
only intended as a guide. Kongskilde disclaims all responsibility for
any damages arisen upon drying
with wrong temperatures or setting
of the drier.

Describtion of
drying operation

If the airflow is excessive when
drying lighter crops, it is necessary
to reduce the airflow by blinding a
part of heater/blower air intake with
e.g. 2 slidable galvanised steel
plates or a tarpolin.
The following description of the
drying operation is general. Each
design of the control unit depends
on the customers’ requirements for
multiprogramming with belonging
conveying equipment etc. and the
automation of the operation.
However, the following main parameters must be considered:
Recommended Drying Air Temperatures:
Feed grain ......................... 80-90°C
Seed grain ......................... 55-65°C
Malting barley .................... 55-65°C
Rape seed for oil ............... 60-70°C
Feed maize ..................... 90-100°C
Choose the hot air temperature on
the thermostat controlling the heater. Be careful with choosing the hot
air temperature, as a too high tem-

The following operation manual
applies to Kongskilde KCD Continuous Flow Drier equipped with AMY
capacity adjustment

1.1

Observe that the drier is filled
with grain in the buffer sections. The upper air channels
must not be exposed, when
the grain sinks during drying.
A large buffer section gives
longer operating hours and a
more smooth function of the
conveying system.
1.2

Setting of gates in the hot air
plenum. Any air gate in the
hot air channel for division in
the hot air and cooling section are opened so that the
drier operates with full heat
in all sections.

1.3

Choose the drying air temperature on the digital thermostat. If the germination
capacity of grain shall be
maintained, the hot air temperature during start-up must
be kept at max. 45°C.

1.4

Start-up the blower/heater.
Check the airflow. Check that
the material is not blown out
of the exhaust air laterals.
When drying grain and oil
seeds with lower bulk density, a reduction of the airflow
may be necessary. Excessive airflow in laterals can be
eliminated by blinding a part
of the air intake of the blower.

1.5

The AMY control is connected and set on “MANUAL”.
Display shows operating time
in % for discharge roller.
Adjust with + or – buttons to
an estimated %-value. The

drying air temperature and
actual drying down requirement. See the recommended

flow time and %-adjustment
of discharger in the enclosed

1. Start of drier
Before every start-up the drier and
heater are cleaned for accumulations of grain and impurities in the
air channels.
It is necessary to start-up the
drier as a recirculating or batch
flow drier in order to secure a
certain drying of the crop in the
lowest part of the drier. We recommend that the start-up drying
is stopped after approx. half of
the normal continuous flow
throughput time in order to avoid
that the crop in the upper part of
the drier is not dried too much.
Thus, the first discharged crop is
not completely dried to target
m.c. and should be spread out,
so that it can be mixed with the
following dry grain in order to
avoid moisture pockets in the
storage cell.

Fill the drier with grain,

in- and outlets approx. once
each hour. If the general final
moisture lies above or below
the requirement, adjustment
is made by a short change
over to manual and change
of the set %-value. If the
dried grain has a moisture
higher than the requirement,
a value must be entered,
which is lower than the first
one entered. If the dried
grain has a moisture lower
than the requirement, a value
must be entered, which is
higher than the first one
entered.

Start the conveying equipment set for recirculation of
grain from drier output back
to buffer. After approx. half of
the continuous flow time
stated in the table.

Adjust air gate in the hot air
channel for division in the hot
air and cooling section, so
that the drier operates with a
suitable number of sections
for cooling – normally 1825% of the total size of the
drier.

Drying capacity depends on
the drier size, heating
source/hot air temperature,
grain type and moisture reduction. It is therefore impossible to give exact setting
values for each drier. Therefore it is important to make a
logbook with data, which
may be of great help for
future drying tasks – e.g. use
the enclosed schedule.

Calculation of drying capacity:
Measure the water content in the
crop to be dried.
Decide the drying capacity by
means of the enclosed drying table
on page 18. The table states recommended drying capacity, %-

value for the operation time of the
rollers and continuous flow time
from the grain enters the drier until
it leaves the drier. Values for moisture reduction from different water
contents and different dry air temperatures are stated.
The stated values are only intended
as a guide, as grain is a biological
material, which may vary from sort
to sort and from place to place. It is
recommended that the actual drying times are noted regularly, so
that a knowledge of the drier performance under local conditions is
obtained.
The tables contain a drying capacity based on:
Drying model
Grain content
Moisture reduction from different
start moistures to a final moisture of
15%.
For different drying air temperatures based on natural air 15°C,
70% R.F.

conditions do not correspond to
those in the drying tables stated
basic values, the following approximations can be used:
Examples:
a. Ambient temperature is 22°C
and the drying air temperature is
80°C = an increase in temperature of 58°C. Therefore the table
value for basic temperature is
used of 15°C + 58°C = a drying
air temperature of 73°C. An
average value between 70°C
and 75°C is used.
b. Starting moisture is 24% and the
required final moisture is 17% =
a moisture reduction of 7%.
Therefore the table value for
basic final moisture of 15% +
7% is used = a starting moisture
of 22%.
Higher Relative Air Moisture at
night reduces the drying capacity
compared to the stated table values.

Example of using the drying
table
KCD 3.05.2, containing 11,5T grain.
The water content of incoming
grain is 19% and a water content of
15% is required.
The combination of heater and drier
allows the drying air to reach a
temperature from 15°C up to 80°C.
The table states that:
Drying capacity is: ............... 4,9 T/T
%-value of the rollers’ operation
time is: ..................................... 27%
Continuous flow time is: ... 140 min.

Correction of calculated drying
times:
Drying capacity is obtained basically from the increase in air temperature versus the water quantity to be
evaporated, depending on the reduction of moisture %. If the actual

Maintenance
Dust mask must be used as protection against dust and mould, when
working with the drier!
Cleaning
1. Clean the drier carefully both inand outside after every season.
The remaining grain can pose
feed for rodents and insects so
as causing growth of fungus,
which infects the next sample of
grain in the drier.
2. The airway must be cleaned
from rust and soot before every
season. This has to be done in
order to avoid that heated loose
metal parts and rust particles
follow the hot air into the drier
and cause ignition there.

3. The hot air channel between the
heater and the drier, as well as
the hot and wet air plenums of
the drier must be cleaned from
dust and grain remains before
and regularly during the season
in order to avoid ignition.
4. Inspect regularly that all electric
motors are clean, and clean
according to requirement. An
