METHOD OF CONTROLLING REMOVAL OF MOISTURE BY EVAPORATION FROM PHOSPHOLIPIDS EMULSION OF SUNFLOWER-SEED OIL IN ROTARY FILM APPARATUS Russian patent published in 2012 - IPC B01D3/30 C11B3/14 F26B5/04 

FIELD: process engineering.

SUBSTANCE: invention relates to oil-and-fat industry. Vapor phase phospholipid mix produced in rotary film apparatus is removed and filtered out into liquid phospholipid fraction and vapor-gas mix in closed-circuit cycle with the help of vacuum pump. Dehydrated phospholipid concentrate of sunflower-seed oil is discharged as finished product and heated in tank to increase its fluidity. Here used is refrigerator made up of compressor, evaporator and heat control valve. Preheating of phospholipid emulsion and subsequent heating of dehydrated phospholipid concentrate are performed by water. Vapor-gas mix after filter is, first, condensed in refrigerator evaporator to discharge condensate and, then, high-pressure pump is used to force said mix into steam generator, thus making closed cycle. Damp initial phospholipid emulsion and liquid phospholipid fraction flow rates are measured in return line as well as the level of phospholipid emulsion and phosphatidic concentrate in heating vessels, flow rate of steam fed into heating jacket of rotary film apparatus, filter pressure difference, heat water temperature and pressure and consumption of heating water for heating initial damp phospholipid emulsion and finished phosphatidic concentrate, coolant temperature in refrigerator condenser and evaporator, condensate pressure and level in steam generator.

EFFECT: higher efficiency and quality.
