DEVICE AND METHOD FOR PRODUCTION OF LOW-TEMPERATURE DEFATTED SOYA BEAN MEAL WITH WEAK SMELL OF BEANS Russian patent published in 2025 - IPC A23L11/00 A23L11/30 

FIELD: food industry.

SUBSTANCE: method for production of low-temperature defatted soya bean meal with a weak bean odour, characterized by that the following steps are carried out: sieving impurities; after sieving impurities soya raw material is sorted by colour sorter for mouldy grains removal and obtaining beans after colour sorting; then the beans are dried, brought to a moisture content of 6–11% to produce dried beans; dried beans are treated with a mill to produce soya petal and bean peel, and soya petal is treated with steam at 85–90 °C for 2–15 minutes to inactivate enzymes, wherein treatment in mill is carried out in gas phase, which is selected from nitrogen, carbon dioxide or argon; then soya petal after inactivation of enzymes is treated using a device for flash degassing in order to remove smell of beans; then soya flap after treatment of flash degassing is rolled to produce bean flakes, which are then leached in organic solvents and dried with hot air to produce dried bean flakes; dried bean flakes are twice subjected to vacuum desolvation at vacuum 60–70 kPa and temperature 70–82 °C for production of soya bean meal defatted at low temperature with weak smell of beans.

EFFECT: invention allows to produce low-temperature soya extraction cake with a weak smell, which has ideal indices of nitrogen solubility, water content, a weak bean smell and other characteristics.
