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).
3.1 TERMS DEFINITION
Oilseed (seed, oil seed) –a common crop seed containing vegetable oil, prepared (i.e.
cleaned and dried) for storage under the local conditions of the seed species
Cake –remaining oilseed material after oil pressing
Vegetable oil –oil obtained from oilseeds or by chemical extraction
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)

OPERATING MANUAL
OILSEED SCREW PRESS FARMET DUO

Press capacity –the quantity of the pressed material entering the press per unit of time,
usually stated in kilograms per hour
3.2 OPTIONAL EQUIPMENT
Electrical Equipment with Frequency Convertor
The frequency convertor is installed directly on the motor terminal block. There are control
buttons on the frequency convertor for switching on and controlling the motor revolutions.
More information is available in the NORDAC SK 205E Frequency Convertor Operating
Instructions.
Electrical Equipment without Frequency Convertor
The electromotor starter allows starting and stopping the motor (including emergency
stop).
Heating Sleeve
It warms up the die before the actuation of the press to ensure better start-up.
Heating sleeve with temperature regulation
It allows heating and stabilization of the temperature of pressing device to the desired
temperature.
Wooden Pedestal under the Press
The pedestal under the press is made from solid stained timber. It stabilizes the press
during operation.
Table under the Press
The metal pedestal under the press ensures stability during operation.
Service Tools
Tools required for disassembling and cleaning the press. It contains a hook spanner, a box
spanner and a cleaning preparation.
Hopper above the Press with Capacity of 20L
A metal hopper above the DUO screw press with the capacity of 20 litres. It is an extension
above two hoppers that are included in the pressing mechanism.

4. ON-SITE ASSEMBLY AND INSTALLATION OF THE
EQUIPMENT
The Owner must perform the assembly according to the instructions of the Producer,
best in cooperation with an expert servicing technician assigned by the Producer.
The Owner must secure a functional test of all assembled parts after the completion of
the Equipment assembly.
The wiring must be executed in compliance with valid standards and documented by a
revision. Any repairs, modifications and other work on the wiring may only be
performed by authorized persons with corresponding electrical qualifications.
The spatial organization of the pressing shop must ensure free access to the Equipment
so that it is possible to perform its maintenance and service without any difficulties.
If more than one piece of equipment is installed in the pressing shop, make sure that
the individual control elements, boxes and equipment are clearly and visibly marked so
that there is no confusion in case an emergency stop is required.
When the Equipment is installed, it has to be properly levelled into a horizontal
position using spacers that do not increase the surface pressure from the supporting leg
so that the Equipment is not twisted or distorted; use suitable base wedge blocks. If the
Equipment is attached to a steel structure together with other heavy appliances, make
sure that the other appliances are installed on the structure prior to the final levelling
using a water level.
When installing the Equipment, make sure that the Equipment is accessible for the
purpose of maintenance and oil change (access to the outlet and inlet openings, oil
level gauges, air release plugs and sight holes).
The Equipment may be installed on a floor with the bearing capacity specified in the
project.
The Equipment is oriented according to the technological disposition.
Make sure that there are tools available. It is also suitable to provide all other
equipment required for maintenance, such as various hand tools, crowbars and lifting
devices.
Check the direction of turning for all rotary devices.
The wiring circuit is included in the annex to this manual.
