METHOD FOR AUTOMATIC CONTROL OF PROCESS OF DRYING PHOSPHOLIPID EMULSIONS OF SUNFLOWER SOIL IN CONICAL ROTARY-FILM-TYPE APPARATUS Russian patent published in 2012 - IPC C11B3/14 

FIELD: chemistry.

SUBSTANCE: method involves measuring consumption of wet starting phospholipid emulsion, steam fed into the heating jacket of the conical rotary-film-type apparatus, dry phospholipid concentrate of sunflower oil, formed in the conical rotary-film-type apparatus, steam-gas-phospholipid mixture removed therefrom, a steam-gas fraction separated therefrom using a filter and a liquid phospholipid fraction in the return line, a mixture thereof with the wet starting phospholipid emulsion, the steam-gas fraction after the filter, water heated in the condenser of a cooling machine, heating water fed for heating the starting mixture, heating water fed for heating the phospholipid concentrate of sunflower oil, condensate output from the evaporator of the cooling machine and condensate removed from the heating jacket, fresh water for feeding the condensate receiver, feeding the condensate into a steam generator. Simultaneously, the power of electric heating elements of the steam generator is continuously determined, as well as the power of drives of the perforated rotor of the conical rotary-film-type apparatus, the compressor, the vacuum pump, feed pumps in feed lines into the continuously operating conical rotary-film-type apparatus for the starting phospholipid emulsion of sunflower oil, removing the ready concentrate of the phospholipid emulsion, feeding steam into the heating jacket from the steam generator, removing the condensate from the heating jacket, returning the liquid phospholipid fraction separated in the filter to the line, recycling heating water into the line for the starting phospholipid emulsion of sunflower oil, recycling water into the line of the ready concentrate of phospholipid emulsion, removing the condensate from the evaporator, feeding the condensate into the steam generator and feeding fresh water into the condensate receiver. Further, real-time control of process parameters is carried out based on the measured parameters using a program-logic algorithm. The program-logic algorithm is in a microprocessor. Further, total thermal power consumption in the drying process is calculated. The derivative thereof is determined from the amount of moisture evaporated from the phospholipid emulsion. Consumption of the starting product is acted on in inverse relation depending on the sign of the derivative.

EFFECT: invention enables to achieve minimum thermal power consumption during the process of drying phospholipid emulsions of sunflower oil, reduce consumption of energy resources per unit mass of the ready product and obtain a ready product of high quality by maintaining the most optimum duration of the drying process.
