Embodiment 1

[0028] Weigh 2000kg of raw material and crush it to a particle size of 1-3mm, then send it to a steamer for 10-30 minutes to dry until the water content of the raw material is less than 7%; then use ethanol solution with a volume concentration of 75% as a solvent, solvent Proportioned with the tea seed cake by weight percentage 3:1, enter the horizontal extraction machine and extract at a temperature of 40-50°C for 1-1.5 hours, the slag liquid is automatically separated after extraction twice, and the extraction liquid enters the Two-stage long-tube evaporator, primary temperature 50-80°C, secondary temperature 70-95°C; after 2-4 minutes, it is automatically input into a vacuum concentration tank, and the remaining temperature is naturally concentrated for 2-4 hours, and dried to a light yellow powder Tea saponin 276kg, yield 13.8%. (Product to feed ratio) is 1.8% higher than the original process. The content of the active substance is 81.5% according to the test; the pH valu...

Embodiment 2

[0030] Weigh 2000kg of raw material and crush it to a particle size of 1-3mm, then send it to a steamer for 10-30 minutes and dry until the water content of the raw material is less than 7%; then use an ethanol solution with a volume concentration of 85% as a solvent, solvent Proportioned with tea seed cake by weight percentage 4:1, enter the horizontal rotary extraction machine and extract for 1-1.5 hours at a temperature of 40-50°C, after two extractions, the slag liquid is automatically separated, and the extraction liquid enters the Two-stage long-tube evaporator, primary temperature 50-80°C, secondary temperature 70-95°C, after 2-4 minutes, it will automatically enter the vacuum concentration tank, after which the remaining temperature will be naturally concentrated for 2-4 hours, and dried to light yellow powder Tea saponin 278.5kg, yield 13.93%. The tests have reached and exceeded the quality level of the original process.

Embodiment 3

[0032] Weigh 700 tons of raw materials, operate according to the process of Example 2, run continuously for 17 days (24 hours a day), and finally obtain 98.5 tons of tea saponin. The yield rate is 14.07%. The product was sent to the Anhui Provincial Product Quality Supervision and Inspection Institute for inspection. The mass fraction of tea saponin 64.30% was 14% higher than the original process 50%; the pH value of 6.0 was 0.1-0.3 higher than the original process; the content of active substances was 81.5% higher than the original process 5-15%; the color is light yellow and similar to the original process.

Abstract

The invention relates to a process for extracting tea saponin from tea seed cakes or meal after oil frying by applying an industrial production device. The process comprises the following steps: crushing the tea seed cakes or the meal (leading the particle size to be 1-3mm), then sending into a steaming and stir-frying cauldron, drying (preventing the water content from exceeding 7%), then leading the material to enter into a material storage cylinder, using a screw conveyor to send the material into a rotocel extractor, and adding a solvent for extraction; carrying out residue-liquid separation (the meal residue can be used as a feed or a fertilizer) after double extraction, leading extraction solution to enter into a long pipe evaporator, removing part of water by double evaporation, and recycling the solvent (which can be recycled); and concentrating the extraction solution via a vacuum concentration tank, then crystallizing and drying, and obtaining a fine saponin finished product for packaging and leaving a factory. A product produced by the process contains 81.5% of active matters, and the pH value is 5.9. Compared with other methods, the process has the advantages of high product purity, light color, high production rate (14%), energy conservation, low consumption, no pollution and environmental protection, and is easy for operation and the like.

Description

technical field [0001] The invention relates to a process for extracting tea saponin from tea seed cake. Background technique [0002] Tea saponin is a kind of nonionic surfactant with excellent performance. It has good performance in emulsification, foaming, lubrication, foam stabilization and decontamination. It is widely used in building materials, pesticide processing, aquaculture, food, light Chemical, pharmaceutical, wool spinning, knitting and other industries; can be used to manufacture various types of emulsifiers, pesticides, rubber, fire extinguishing materials, film, hair care products, foamed reinforced concrete, shrimp breeding agents, etc., can develop more than 180 A series of products with huge development potential and broad market prospects. Regarding the extraction and application of tea saponin, there have been many years of research and practice in my country. In summary, there are usually 4 methods, namely water immersion, adsorption, microwave / light ...
