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.

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.
