EXTRACTING METHODS FOR PERFUME, FOOD AND PHARMACEUTICAL PURPOSE Russian patent published in 2008 - IPC C11B1/10 

FIELD: fat and oil industry.

SUBSTANCE: base material is cyclically heated under effects of microwave energy until preset temperature is achieved. Obtained extract has to be cooled to the preset temperature. Each cycle, base material is first heated by microwave energy to 40-50°C temperature. Simultaneously, fine disperse extracting agent is injected into effective volume of extractor with exposure time 0.5 minutes at frequency of 2 cycles per minute and pressure increase in effective extractor volume to 3000 - 4000 mm of m.c. Secondly, material temperature is decreased to 25-30°C and pressure in extractor effective volume is also decreased to 10^-1 - 10^-2 mm of m.c. Microwave energy effects only at heating stage lasting no more than 10 minutes. Extracting agent injection is terminated at the last two minutes of extracting.

EFFECT: reduces response time and energy intensity of extracting process and broadens equipment performance capabilities based on extracting process.
