Bottom Trough, And Bottom Aspirator, Sampling Unit; Dryer Furnace; Electrical Equipment; Frame - Mepu K-SERIES Operating Manual

All bottom hatches must be closed during the drying process or
filling the dryer!
The bottom hatches must not be closed, if there is grain in the
bottom trough (risk of damage).
The driving engine of the feeding apparatus is an inverter-controlled
gear motor, from which the rotating movement is transmitted
through the chain drive to the feeding shafts. At the production
facility the grain circulation rate is adjusted to approximately 182 hl/ hour. The feeding
amount can be freely adjusted by rotating the control
knob on the electrical switchboard.

4.8 Bottom trough, and bottom aspirator, sampling unit

The steep-sided bottom trough is made of durable hot
galvanized steel plates. The bottom aspirator removes
dust and steam from the bottom trough, keeping the
elevator clean throughout the entire drying process.
From feed rollers the slanting sides of the trough direct
grain to the bottom conveyor on the bottom of the
trough, which removes the grain to the elevator. The sampling unit is located in the
rear of the bottom trough. The sampling unit facilitates monitoring of the drying
process. Remove the cover and tilt the sampling tube downward and let grain fall into
the sampling bin.

4.9 Dryer furnace

All dryer models feature an efficient and durable furnace. Power range of the furnaces:
250–500 kW. The blower capacities /air rates are: 4.0–11 kW / 14000–24500 m
The burner flame burns in the middle of the cylindrical firebox, and heat is transmitted
into the vertical plate heat exchangers. The combustion chamber is made of fire-
resistant steel. The vertical heat exchangers release heat evenly and efficiently. This
ensures excellent efficiency and durability of the furnace.

4.10 Electrical equipment

The electrical equipment and automatic systems of the dryer are installed at the
factory. The dryer is ready for use as soon as the dryer's equipment is connected to the
respective outlets, the unit is connected to the power network, and
the oil burner hoses are placed into the oil tank.
Before starting any maintenance work remember to always turn
the main switch into the OFF position, or disconnect the power
cables from the network.

4.11 Frame

The sturdy steel beam frame and large air filled rubber tyres make it possible to
transport the dryer at the maximum speed of 50 km/h. During the drying process, the
frame must be supported at five support points. On M240k and larger dryers the wheel
shaft is supported with shaft supports. The drawbar can be detached to save space.
Towing of a mobile dryer filled with grain is categorically prohibited.
