Problems solved by technology

[0003] Lycopene itself is fat-soluble and can be extracted with a solvent. The extracted mixed oil needs to be concentrated and desolvated. In actual production, a tube evaporator is often used for desolventization. The mixed oil loses solvent in the tube evaporator, and the lycopene The concentration of lycopene increases, but due to uneven heating, the solvent content of the mixed oil is different in different positions. The solvent of the mixed oil near the tube wall and in the tube with high heat evaporates quickly, and the lycopene is easy to crystallize and adhere to the inner wall of the tube continuously. Accumulation, blockage of tubes, so that evaporation cannot be carried out continuously

Embodiment 1

[0024] The lycopene mixed oil containing solvent (n-hexane:acetone volume ratio is 2:1) with a content of 95% is pumped into the inlet of the special evaporator by a liquid injection pump. -70°C hot water, pump a vacuum of -0.06 to -0.07MPA above the tubes, take a sample of the mixed oil from the evaporator into the flash box and test that the solvent content is 71.3%, pass 50-70°C hot water through the jacket of the flash box, and pump - 0.06 to -0.07MPA vacuum, use the outlet on the right side of the bottom of the flash box, take the mixed oil from the bottom of the filter bag to detect that the solvent content is 63.6%, after 42 hours of continuous evaporation, the PLC detects that the pressure difference between the upper and lower filter bags reaches the critical value, and automatically shuts down Electric butterfly valve on the right, open the butterfly valve on the left and send out an alarm message, manually replace the filter bag on the right and collect 15.6kg of lyc...

Embodiment 2

[0026] The lycopene mixed oil containing solvent (the volume ratio of n-hexane and acetone is 2:1) with a content of 98% is pumped in from the inlet of the special evaporator by a liquid injection pump. -70°C hot water, pump a vacuum of -0.06 to -0.07MPA above the tubes, the evaporator enters the flash box mixed oil sampling test solvent ratio is 71.8%, the flash box jacket is filled with 50-70°C hot water, and the top pumps - 0.06 to -0.07MPA vacuum, use the left outlet at the bottom of the flash box, take the mixed oil from the bottom of the filter bag to detect that the solvent ratio is 63.9%, after 72 hours of continuous evaporation, the PLC detects that the pressure difference between the upper and lower filter bags reaches a critical value, and it will automatically shut down The left electric butterfly valve opens the right butterfly valve and sends out an alarm message, manually replaces the left filter bag and collects 15.7kg of lycopene crystals from the left filter b...

Abstract

The invention discloses a concentration desolvation method and apparatus of lycopene extraction mixed oil. The method comprises performing evaporation with a tube evaporator and performing secondary evaporation crystallization with a flashing case. The method is characterized in that in the tube evaporator, a first group of tubes are used for evaporation, uniform mixing is carried out, and a second group of tubes are used for evaporation, wherein the flow rate of mixed oil in the second group of tubes is larger than that in first group of tubes, and the tube evaporator allows the solvent content to be reduced from 90-99% to 70-72%, and finally a flashing case is used for secondary evaporation crystallization. The method and apparatus allow a solvent in lycopene extraction mixed oil to be efficiently continuously evaporated.

Description

technical field [0001] The invention relates to the technical field of natural extract concentration, in particular to a method for concentrating and desolventizing mixed oil extracted from lycopene, and a device for concentrating and desolventizing. Background technique [0002] Lycopene is well-known for its superior antioxidant function. It is made into soft capsules, microcapsules, oil-soluble suspensions, tablets, powders, injections and other products in various forms and specifications. It is used in the medical and health care markets. Over the years, it has been unanimously favored by the domestic and foreign health care product markets. [0003] Lycopene itself is fat-soluble and can be extracted with a solvent. The extracted mixed oil needs to be concentrated and desolvated. In actual production, a tube evaporator is often used for desolventization. The mixed oil loses solvent in the tube evaporator, and the lycopene The concentration of lycopene increases, but d...
