LINE FOR INTEGRATED TWO-STAGE PROCESSING OF OIL CROPS Russian patent published in 2015 - IPC C11B1/00 

FIELD: food industry.

SUBSTANCE: line for integrated two-stage processing of oil crops includes 2 section; the first section contains bins for storage of seed meal of various oil crops such as sunflower, rape and camelina with volumetric dosers installed in the bins lower parts, shaking sieves, electric magnets, forepresses, a three compartment sludge trap, an automatic scale, a vessel equipped with an anchor stirrer for mixing vegetable oils produced, a pump, filter presses for filtration and a vessel for composite virgin oil. After separation of coarse inclusion on shaking sieves, seed meal of varied oil crops such as sunflower, rape and camelina is supplied, in a uniform layer, to the electric magnets where it is cleared from ferric impurities; then it is delivered for preliminary oil expression to the forepresses with one forepress operating alternatively processing various oil crops; forepress press cake is delivered into the bins fore forepress press cake while forepress oil is supplied into the three compartment sludge trap; then oil is weighed on the automatic scale and dosaged, depending on the recipe formula, into the vessel equipped with an anchor stirrer for mixing vegetable oils; then oil is pumped to the filter press for filtration and further into the vessel for composite virgin oil and for storage; installed downstream the forepresses is the second section equipment represented by bins for forepress press cakes such as sunflower, rape and camelina with volumetric dosers installed in their lower part, electric magnets, crushers, weight bins with volumetric dosers installed in their lower part, an auger steamer mixer, a tank roasting pan, an expeller with a fitting installed for press cake granulation, a sludge trap, a pump, filter presses for filtration, a vessel for composite pomace oil; within the said section, forepress press cakes of various oil crops from the bins for forepress press cakes with volumetric dosers installed in their lower part pass through electric magnets and further delivered for milling into the hammer crushers to be then delivered into the weigh bins from where the product, portioned depending on the recipe formula, is supplied into the clutch steamer mixer and further into the tank roasting pan; after thermal treatment, the product is supplied for final oil expression into the expeller with a fitting installed for press cake granulation; composite granulated expeller press cake is supplied for storage while expeller oil is supplied into the sludge trap; oil is pumped for storage to the filter presses for filtration and further into the vessel for composite pomace oil and for storage; water from the water jacket of the vegetable oils mixing vessel is supplied into the steam heater in a closed cycle mode; from the steam heater, superheated steam is supplied into the water jacket of the tank roasting pan wherefrom it is supplied into the auger steamer mixer ; then spent steam passes through the condenser filter; then produced water is delivered into the water jacket of the vessel equipped with an anchor stirrer for mixing vegetable oils and further into the steam heater.

EFFECT: invention allows to expand he technological capacities of the line for integrated two-stage processing of oil crops allowing to produce composite vegetable oil and composite granulated expeller press cake having a high quality, balanced in terms of fatty acids content, possessing a therapeutic-and-preventive effect to fodders as well as to expand the range of vegetable oils and press cakes manufactured and use the line as an energy saving one.
