Problems solved by technology

[0004] However, the extraction rate is still not high enough in the existing tea pigment extraction method. Meanwhile, with the continuous development of industrialization, in order to increase the output, the ultrasonic extraction tank in the existing tea pigment extraction method is also correspondingly obtained. When the volume of the tank body reaches a large level, the temperature of the internal extraction liquid near the heat source exceeds 100 degrees when heated, and the place relatively far away from the heat source fails to reach the required processing temperature of 70 degrees, which affects the production of tea pigment. Extraction effect and extraction efficiency need targeted improvement design

Abstract

The invention discloses a high-purity separation method for physically extracting tea pigment. S1, raw material pretreatment; s2, tea pigment extraction; s3, separation and purification; and s4, concentrating and drying; the invention further discloses high-purity separation equipment for physically extracting the tea pigment, the high-purity separation equipment comprises a tea leaf crusher, an ultrasonic extraction tank, a central control box and a safety valve arranged on the ultrasonic extraction tank, and a discharge port in the lower end of the ultrasonic extraction tank is communicated with the negative pressure generator through a connecting pipe. The outlet end of the tea leaf crusher is communicated with a feeding hole of the ultrasonic extraction tank; and a plurality of groups of temperature sensing belts are annularly arranged on the side wall of a tank body of the ultrasonic extraction tank, and an electric heating element is arranged in an area close to each temperature sensing belt. According to the method, the material-to-liquid ratio, the ultrasonic extraction temperature and the ultrasonic extraction time are refined, so that the extraction rate of the tea pigment is increased, and the equipment can ensure that the temperature of the extracting solution in the tank body uniformly rises to the set temperature, so that the extraction efficiency is ensured.

Description

technical field [0001] The invention belongs to the technical field of tea pigment extraction, and in particular relates to a high-purity separation method and equipment for physically extracting tea pigment. Background technique [0002] Tea is one of the traditional beverages with multiple functions such as nutrition and health care. The tea pigments (theaflavins, thearubigins and theabrownins) extracted from tea leaves are widely known as natural pigments and have many benefits. Most experiments show that tea pigment has anti-oxidation, enhances immunity, lowers blood pressure, lowers blood fat, lowers blood viscosity, inhibits experimental tumors and other pharmacological effects. With the development and in-depth research of various health functions of tea by researchers, it has gradually become a problem for researchers to effectively extract tea pigments from different teas. [0003] So far, little research has been done in this field. Initially, researchers used b...
