METHOD AND APPARATUS FOR OBTAINING FOOD PRODUCT FROM RAW PLANT MATERIAL Russian patent published in 1999 - IPC

FIELD: food-processing industry. SUBSTANCE: method involves regulating working pressure P and temperature T in hermetically sealed vessel containing raw plant material and liquid within the range of 4•10^-4<= β P/T <0.34 δ,, where β [ C/atm] is experimental coefficient depending on nonuniformity of temperature distribution in volume of raw plant material, its heat capacity and heat conductivity and selected within the range of 0.78 <β <2.4. Apparatus has heat-carrier generating unit and grinding-cooking unit with cutting mechanism provided with knives and perforated separator. Apparatus is further provided with mechanism for withdrawing ready food product. Working volumes of heat-carrier generating unit and of grinding-cooking unit are within the range of 1.1 <=(V1 + V2) / V2 = 12 and are related with volumes V3 of liquid heat-carrier in heat-carrier generating unit and V4 of solvent in grinding-cooking unit within the range of 1.1 <= (V1 + V2 + V3 + V4) / V2 < = 8.3. Ratio of value L2 of minimum gap between knives cutting edges and value L3 of maximum cross section of perforations in separator walls is within the range of 1 < =(δ L2 + L3)/L3 <= 130. EFFECT: increased efficiency and improved consumer properties. 3 cl, 2 dwg
