ANTTI PLUG&DRY
Read the Installation and Instruction Manual carefully before installing the machine and putting it into operation.
SELECTING LOCATION FOR THE DRYER
Locate the grain dryer as a part of the farm's centre of operations, taking into account possible tra󰀩c, noise and
dust problems. Construct the roads in a manner enabling them to be tra󰀩cked with a full trailer round the year.
If possible, locate the heater on the facade side of the building. When selecting location for the heater, observe
in particular that it requires large amounts of clean air. The suction opening of the heater must be located as far
from the outlet air pipes as possible, on the other side of the building. If you have doubts concerning the location,
negotiate in advance with the local building and road authorities, and the re chief.
The distance from the grain dryer to the land of the neighbour shall be at minimum 15 m, to the neighbouring
building 20 m, to your own residential building15 m, and to an outbuilding 12 m. (The minimum distance to your
own buildings may vary from municipality to municipality, depending on how the new regulations are being locally
interpreted). For dryers of category P2, the required distances may be shorter. Under certain conditions, a package
dryer may fall into category P2. Consult the local re chief or building supervisor for detailed instructions.
FOUNDATION
GROUND PRESSURE
When selecting suitable founding method for your dryer, apply the following base values for di󰀨erent soil types:
Moraine 0,4 – 0,8 MN/m2
Gravel 0,2 – 0,6 MN/m2
Sand 0,15 – 0,5 MN/m2
Fine sand 0,1 – 0,4 MN/m2
Clay and ne silt:
- soft (easy to work) 0,025 MN/m2
- tough (hard to work) 0,050 MN/m2
- solid (extremely hard to work) 0,1 MN/m2
If you consider that the load-bearing capacity of the soil is di󰀩cult to determine, assign a specialist or order a ground
survey. It is often a good idea to establish the form of the rock by means of a ground survey or a test excavation.
Typically, the ground pressure caused by a dryer is 0.5–2.0 kg/cm2 when the foundation is of raft type.

Antti-Teollisuus Oy 5 408116 03-2020
THE SPACE REQUIRED FOR THE INSTALLATION
The minimum requirement is that the foundation drawings are being followed.
In addition, you must take into account the space required for the installation, and the load-bearing capacity of the
soil under the mobile crane.
The goods to be transported can be over 3 metres wide and fairly long. Therefore, the access to the foundation of
the dryer must be unobstructed, and su󰀩cient space must be reserved for turning the vehicles.
For the erection of the dryer, the mobile crane must be provided with unobstructed access near the installation
site and a su󰀩ciently sturdy standing base. There must not be any aerial electric or telephone lines at the erection
site, within the reach of the mobile crane.
Instruction manual for erecting and operating the machine
This manual is intended for professional farmers. The use of the machine requires normal skills and general
knowledge of farming.
Grain dryer type
This manual deals with installation and use of ANTTI PLUG&DRY.
PRESENTATION OF THE MACHINE
- Grain dryers are intended for drying of grain and seeds.
- The drying process comprises four phases:
1. During the lling phase, the elevator transfers the grain from the lling hopper of the dryer into the dryer.
2. During the drying phase, the grain circulates inside the dryer, and simultaneously, hot air is being sucked
through the grain layers.
3. During the cooling phase, the grain is being circulated inside the dryer, and cold outside air is being sucked
through the grain layers.
4. The ready-dried and cooled material is transferred by means of an elevator to the storage or to be loaded.
The dryer is delivered, as ordered, as pre-assembled units or in parts, and the nal assembly shall take place at
the installation site.

Antti-Teollisuus Oy 6 408116 03-2020
- The pedestal of the dryer comprises the dryer base and the feeder. The drying sections are installed on top
of the base.
- The drying unit comprises drying sections with triangular air ducts. The top tanks are stacked on top of the
drying unit.
- The volume of the dryer depends on the number of the sections and the top tanks, being installed one on top
the other.
- In addition to the main parts itemised above, the delivery also includes a number of smaller parts, the instal-
lation of which is described more in detail later in these instructions.
In dryers, the most signicant source of noise is the axial blower/axial blowers. Refer to the blower manual for
detailed information.
SAFETY
The dryer base has moving feeder parts that can cause an injury, if all the cover plates and hatches are
not properly closed, while the machine is in operation!
NOTE!
Before opening or closing the bottom troughs, ensure that the inspection and cleaning hatches in the
dryer base are closed.
Follow the local instructions for occupational safety.
INSTALLATION OF THE ANTTI PLUG&DRY
Refer to the erecting instructions 408076 for the dryer for installation of the sections and the other basic components.
These instructions deal with the installation of the Plug&Dry dryer's model-specic components.
The installation work of the dryer requires precision. The work must be carried out on various levels, even at high
elevations. Therefore, in addition to good installation skills, the work requires proper sca󰀨olding/use of aerial work
platforms and observation of all the safety issues. Especially, the dryer base and the sections are heavy. Lifting
them requires su󰀩ciently powerful machinery.
Pre-connected wiring is used for installations in the electric centre. Before starting the use, make sure that all the
electric appliances are in order!

Antti-Teollisuus Oy 7 408116 03-2020
Weight of the dryer's components:
2W 3W 4W
Base 725 kg 900 kg 1320 kg
Section (2 pcs, without air channel ends) 1080-1190 kg 1520-1635 kg 1960-2115 kg
Top section 220 kg 280 kg 355 kg
Top section with cover and handrails 400 kg 520 kg 655 kg
Please observe, when lifting the heavy components of the dryer:
- use all the lifting lugs on the components
- use the lifting lugs and a bracing when lifting the ready-assembled top tank
- ensure that the lifting hooks stay in position in the lugs, and that the crane being used is su󰀩ciently powerful
- never go under or too near the components to be lifted
- the crane must be able to lower the component to be lifted slowly and precisely into position
- reserve 3–5 tools that can be used as guide pins such as, for example, pin punches of 5–8 mm in diameter
Provide all the horizontal seams with sealing band.
Note! If you wish to stack several sections, and lift them on top of the base in one go, use the separate lifting lugs
(501010). Refer to the erecting instructions 408076 for detailed instructions. Attach the lifting lug by eight M8
bolts. Brace the lugs by xing battens of 50x100 by the two holes to support the lugs so that the section end will
not bend. Use the same lugs for lifting the top tanks.
The dryer can be assembled from larger sub-assemblies. All the drying sections and the top tanks can be lifted
into place using the robust lugs on the top. The maximum load, allowed to be lifted is 6,750 kg An example: the
top tanks and the top tank cover with handrails can be assembled while the section is still on the ground. Tighten
all the bolts – use M10 bolts for xing the vertical supports. Lift this large sub-assembly on top of the base or the
lower-lying sections.
NOTE!
The total weight of the sub-assembly is several tonnes, so a heavy crane is required. Verify the load-bearing ca-
pacity of the soil, before the lifting.
