The oil presses are screw-type machines used for mechanical extraction or pressing the vegetable oil from oilseed crops. It is a non-chemical technology that results in perfect ingredients such as oil and oil cake for using in feed industry.

  • vegetable oil from sunflower seeds, soybeans, canola, flax, olive stones, grape seeds, mustard seeds, etc
  • oil cake also called as meal from sunflower, soybean, rapeseed or canola with the residual oil not more than 8-10%

What actually happens inside the oil press? Let us shortly and easily explain. The feedstock is moved along the press cage being squeezed and pressed. Under pressure the oil seeps out through the press cage gaps and gathers into the oil reservoir below. The oil is filtered to remove the fine solid particles, it is purified from other substances and can be used as a livestock feed component or as a food product.

With seed processing oil is usually the main goal of our customers, but except the oil, we also get the press cake with the oil content of 7-8% and temperature 120-130°C. After the oil cake had been discharged from the press, it is cooled down with the cooler. Its final temperature afterwards is 10-15 degrees higher than the temperature in the shop and the resulting oil cake is ready for storage for up to 3 months.

Technologically the oil presses could be differentiated into:

  • first extraction presses used for preliminary mechanical oil extraction;
  • expellers used for final mechanical oil extraction

cold oil presses (processing temperature is up to 60°C)

hot oil presses (processing temperature is from 60°C)

One type of oil seed may differ to the next and that have a direct effect on the operating parameters of the oil press, so there is a difference between raw materials and fat content.

We manufacture all types of oil presses constantly improving and modifying them to meet our client demands.

BRONTO oil presses have a user-friendly design for operation and maintenance, high wear resistance of press cages which is from 5,000 tons of processed raw materials. The oil presses, gears, bearing units, motors have been designed to withstand the double and even triple overload of the nominal capacity.It easy to assemble and disassemble BRONTO oil press without any additional lifting of equipment. High production capacity, reliability and non-stop operation are guaranteed.
