Seed preparation

Oilseed comes from the intermediate bunker through the magnetic separator into the inclined dosing conveyor controlled via a frequency converter. Further the seed continues into the cleaning section. Cleaned oilseed then passes through the temperature stabilization (in winter period it is heated up to temperature of 15-20 °C) and continues into the pre-press hopper.

Technology versions

CP1 – one-level cold pressing

Press FL 200 is implemented in this technology as a “full-press” configuration. The modular pressing line can be fitted with one to four FL 200 presses.

CP2 - two-level cold pressing

The press FL 200 is used as a pre-press. The pressing cake is then conveyed through the inclined conveyor into the FL 200 final press.

EP1 – one-level pressing with extrusion

The raw material is led into the hopper and passed into the extruder FE 250, where the process of material extrusion takes place. Afterwards, the material continues through the inclined conveyor into the FL 200 final press. This technology is designated mainly for soybeans.

EP2 – two-level pressing with extrusion

The press FL 200 is used as a pre-press. The pressing cake from the pre-press falls into a hopper and continues into the extruder FE 250, where the process of extrusion takes place (mechanical kneading, short-term heating to high temperature under high pressure, with consequent expansion). The extruded material continues through the inclined conveyor to the FL 200 final press.

Separation tank

The separation tank is equipped with an automatic drainage that is picked from the tank by the blades on the chain conveyor. Separation of the solids is carried out on a sieve and the solid particles are returned to the press once again where it is mixed together with the pressing cakes from pre-presses or with an extrudate. In the separation tank, the oil can be heated by means of heating rods to facilitate filtration. This is especially important when filtering soybean and sunflower oil.

Oil Filtration

For all technologies, oil expelled from the presses FL 200 is retained in the sedimentation tank, which forms an integral part of the module. The tank is equipped with automatic removal of solids, which are consequently returned for re-pressing into the final press. Oil is consequently pumped into a manually-cleaned plate filter. Filtered oil then continues into oil storage tanks (see options).

Pressing cake storage

Pressing cake is conveyed via the tube-type screw conveyer out of the module of the pressing line, beyond the partition structure, which forms the pressing cake storage.

Electrical installation

Two levels of control, CLASSIC and CLEVER, can be selected for the COMPACT modular pressing shop.

Control level CLASSIC

Includes complete electrical installation to drive and control all devices, based on classical elements (contactors and relays). Sensors control the overpressure backfill, the maximum extruder temperature, and the maximum oil level in the tank to automatically stop material dosing into the Press section in the event of a failure. The control is done by the buttons on the switchboard, which is an integral part of the pressing module. The material dosing (line power) can be controlled by adjusting the speed of the feed conveyor. The control system also includes control of heating elements of the heating conveyor and sedimentation tank, including the possibility of setting the temperature and automatically monitoring the maximum temperature.

This version does not include computer control or visualization.

Dehulling and hull separation (for sunflower /soya)

It removes a part of hulls prior to the pressing. This decreases the content of fibre in pressing cakes and it becomes more valuable feed. We will gladly send you separate Technical information and following offer for the technology of dehulling.

Soybean crushing for EP1

This OPTION is intended for COMPACT EP1. Before entering the extruder, soybeans are crushed to fine fraction, which improves the capacity of the extruder and the press, and at the same time it reduces their wear. The OPTION consists of a hammermill, a screw conveyor and related electrical installation. This OPTION is installed behind the cleaning unit.

Granulation of hulls (for sunflower /soya)

It follows-up the OPTION Dehulling and hull separation. The technology of granulation (pelleting) of hulls serves to process sunflower hulls into the form of granules (pellets), which are more suitable for handling, storing and subsequent utilization. Granulation considerably decreases volume of the hulls and thus the requirements for storage dimensions.

Water dosing into the extruder (for technologies EP1, EP2)

This OPTION includes a frequency controlled dosing pump and injection nozzles for water dosing into the entry part of the extruder. This is useful if the seeds at the input are over-dried.

Active breaker at the output of extruder

This OPTION is required for processing those oilseeds which create a cohesive mass, for example sunflower. Active breaker breaks the output material into smaller parts and therefore allows their passage through other transport ways. It is not necessary for processing of rapeseed and soya. OPTION is mounted at the output of the extruder.

Conversion from EP2 to CP2

This OPTION is intended for COMPACT EP2 in case the customer wishes to use it for cold pressing (CP2). In such case it is necessary to remove the extruder and to install a conveyor instead, which is supplied within this OPTION.

This OPTION consists of the screw conveyor and related electrical installation. This OPTION is suitable only for COMPACT with standard sedimentation tank. It cannot be used for COMPACT with short tank (marked „S“), which is equipped with extruder bypass as a standard.

Independent processing of oils (for EP2)

This OPTION ensures independent collection and filtration of oils from the 1st and the 2nd stage of pressing. It contains a standalone homogenization tank, pump, fittings and the related electrical installation.

Filtration is intended to be done on the standard plate filter cyclically, filtered oil is to be pumped into two separate storage tanks (storage tanks are to be supplied by the customer or ordered as an OPTION).

Oil storage 1m3

It contains 1m3 - IBC-container which serves as a simple oil storage. We advise to use at least 2 pcs. of containers.

Oil storage 7m3

It contains 7m3 - IBC-container which serves as a simple oil storage. We advise to use at least 2 pcs. of containers.

Dispensing oil pump

It serves for pumping the oil from storing tanks into transport containers or tank truck. A part of the pump is a working space with manual valve for bottling the oil into PET bottles or cans.

Conversion kit for soya pressing

This OPTION is defined for COMPACT in a version EP2 (originally intended for rapeseed or sunflower) which is supposed to be used alternatively for soya processing. The OPTION includes working screws, inserts of the extruder in the implementation of soya extrusion.

Control system CLEVER

In case this OPTION is chosen, the pressing line will be supplied with installed control system CLEVER, using a touch panel and a PLC controller. This version secures accurate controlling of the pressing line. All the push-buttons from the switchboard are removed; the technology is controlled via the touch panel. This OPTION integrates the FIC automatic control system and allows future expansion of the line.

PC Visualization + Remote Access

This OPTION can be used only in case that the technology is equipped with the control system in the version CLEVER (PLC-based control system). The OPTION consists of a standalone computer with the respective SW for visualization and control of the process. We recommend placing this computer in a dedicated control room. The computer serves for visualization of various operational states and the whole technology can be controlled from it.

The OPTION includes also the function of REMOTE ACCESS, which – after connection to the Internet – enables to supervise and control the technology from a remote workplace. This function can be also used for the purposes of Farmet service support and to secure operative help and support to the user in case of emergency operation states of the technology.

Remote Access

This option secures the function of REMOTE ACCESS (see above), but without the visualization computer. This OPTION is recommended in cases, when it is not possible or suitable to have a dedicated control room close to the pressing shop. The OPTION Includes a minicomputer installed inside the switchboard, together with the respective SW, without any monitor or keyboard.
