Pre-treatment of seeds before pressing

Intermediate container for a ready reserve of seeds
Magnetic separator of metallic impurities

Recommended options:

  • Heat stabilization of seeds RECU – making use of the waste heat of the flash steam coming out at the extruder output. The heat is transferred into the incoming seeds via a heat-exchanger.
  • Seed cleaning – protecting the technology and increasing lifespan of the pressing machinery
    • Vibratory separator with aspiration – separates gross impurities (stones, straws) and smaller dust particles
    • Destoner – removes heavier particles such as stones.

  • Continuous weighing of seeds – tensometric scale providing information about the amount of processed material
  • Dehulling and hull separation (for sunflower or soybean processing) – removal of hulls before the pressing decreases the content of fiber in the press cake, increases protein percentage, improves press cake value as a nutritional source. At the same time, the yield and quality of the vegetable oil go up too. Just recently we have also introduced dehulling of rapeseed!
  • Granulation (pelletization) of hulls – this technology serves for processing of sunflower hulls into the form of granules/pellets

Cold pre-pressing

Treated seeds enter the press where they are gradually compressed while the oil is coming out through outlet slits.

The cold-pressed vegetable oil thus obtained has a high quality and a low content of phospholipids. The presses are by default equipped with an integrated separator of solids; these particles are fed back into the press and re-pressed. The sedimentation tank is equipped with an oil stirrer.

Extrusion of press cake

The mechanically partially broken up and heated press cakes continuously enter the extruders for a further mechanical and thermal treatment via extrusion.

During extrusion, anti-nutritional substances are eliminated, proteins and starches are transformed, the material is sterilized by the destruction of germs and molds. The cake has a high nutritional value and represents a valuable feed for livestock. The extrusion process itself is thanks to the pre-pressing step significantly less demanding of energy.

Regulation of temperature in the working unit leads to an optimal digestibility of proteins for pigs, poultry, fish and ruminants (increasing the content of by-pass protein). This regulation is done automatically via an output nozzle at the output of the extruder.

Recommended options:

  • Active extrudate breaker – a technology that breaks up the continuous mass coming out of the extruder into smaller particles, allowing thus its easier passage in the subsequent transport paths. We recommend this option for sunflower processing.
  • Water dosing into the extruder – this option is convenient if the incoming seeds are too dry (moisture level less than 8% - not enough for extrusion). This option includes a frequency-controlled dosing pump and injection nozzles.

Final hot pressing

Final hot pressing provides high oil yield thanks to disruption of the cellular structure of the seeds in the preceding extrusion step. In this step, low content of residual fat in the press cake is achieved. Final presses are equipped with system for shaft cooling and an integrated cake breaker.

Recommended options:

  • Integrated granulator – forms press cake in the shape of granules of a diameter 10mm
  • Source of cooling water for the shaft (for presses FS 1010 and FS 4015) – cooling of the central part of the shaft prevents overheating of the press
  • Press cake moistening – ensures optimum moisture level of the cake at a required level, including the option of adding additives into the injected water
  • Cake granulation – this option includes a granulator intended only for the granulation of warm cakes immediately upon pressing
  • Cake cooler – ensures cooling of the cake to a temperature not more than 20°C above the ambient temperature

Automatic vegetable oil filtration

Automatic filtration is an equipment intended for the filtration of vegetable oils, especially for the removal of solid particles, which are a by-product of oilseed pressing. This technology is offered for medium- and large-scale press shops.

Filtration may be followed by further raw oil processing by refining: This process involves separation of substances that are undesirable for the use of the oil in food purposes or technical goals. In refining, phospholipid content is significantly decreased, as well as that of fatty acids or waxes (sunflower oil). Odors and colorants are removed as well. Do not hesitate to contact us for more detailed information on the refining technology.

Process control and visualization system – Farmet Intelligent Control (FIC)

FIC checks numerous values and parameters. It provides both sound and visual cues to the staff whenever the values are off. The system by itself can respond by technology shutdown, when necessary.

FIC comes with the following modules:

  • power protection (protection of the presses)
  • press effect (intelligent control system of the press)
  • remote access
  • data save (data archiving)
  • access control (a system for remote control)

Recommended options:

  • Press shop management

A software extension of the FIC system. It allows, in combination with remote control by Farmet, to optimize the process of seed processing and thus maximize its economic benefits.

Press shop management consists of two parts:

  • the application for press shop operators (an electronic operation log keeping track of the analyzed samples)
  • the application for the management, working via a web interface, allowing the managers to obtain comprehensive information about technology usage
