OPERATING MANUAL
OILSEED SCREW PRESS FARMET DUO
Page 17 of 48
The pressing unit consists of an aluminium hopper, a press screw, a die, a heating sleeve
nut, a nozzle holder, a nozzle for cakes and a heating sleeve.
Press Description
The presses can be assembled into batteries placed on one pedestal with a joint discharge
chute and a belt conveyor for carrying away the pressed cakes in the form of granules. Each
press has two press heads, two press screws, two dies, driven by one gearbox and one
electromotor.
Press Gearbox Description
It is a wet-operation gearbox; it is a single reduction gearbox for the operation of two
screws of one press, designed as a compact mono-block. The box is a casting with a bottom;
bearings: conical (ISO 355 – 7FB corresponds with 31310), ball (6306).
The output hollow shafts of the gearbox are designed to be inserted into the press screw.
The shafts are sealed with Gufero shaft seal. The gearbox is lubricated by wading wheels in
an oil bath and oil spray inside the box.
Press Function Description
The oilseeds are brought into the hopper. This may be solved either by a standpipe from a
higher floor of the building or by a separate container above the press or above the press
battery. When the electromotor is activated, the seeds from the hopper are collected by the
screw that presses the seeds into the head (nozzle holder) in the place of the perforated die
which presses out oil that runs down into the chute (not included in the delivery). The pressed
cakes go through the nozzle where they are pressed to come out in the form of granules.
When actuating the press, the pressing mechanism must be heated to the temperature of 60°C.
Use the heating sleeve (optional accessory).

Crude oil – vegetable oil after pressing (or extraction) and filtration without any other
treatment (filtered oil)
Oil pressing – pressing oil from oilseeds by mechanical force – pressure
Screw press (for oilseeds) – equipment for pressing oil by creating pressure using a
rotating screw with variable geometry in a closed perforated filter (also called the bin)
Oil separation – separation of gross mechanical impurities from oil
Oil filtration – separation of mechanical impurities from oil (particles)
