CN-224215876-U - Vacuum cooling system is used in tea pigment production

Abstract

The application discloses a vacuum cooling system for tea pigment production, which comprises a base, a frame, an air inlet tank, a cooling tank and a vacuum air storage tank, wherein the frame is arranged on the base, the air inlet tank is arranged on the frame, the cooling tank is arranged on the frame, the air inlet tank is communicated with the cooling tank, and the vacuum air storage tank is communicated with the cooling tank. In the tea juice concentration process, the vacuum pump extracts high-temperature steam from the concentration evaporator to maintain the vacuum degree in the concentration evaporator and reduce the boiling point of the tea juice in the concentration evaporator, so that the energy required by tea juice concentration is reduced. The high-temperature steam pumped from the concentrating evaporator by the vacuum pump firstly enters the air inlet tank, then enters the cooling tank from the air inlet tank for cooling, is discharged into the vacuum air storage tank after being fully cooled in the cooling tank, and flows into the vacuum pump from the vacuum air storage tank. Through the steps, high-temperature steam can be effectively prevented from directly flowing into the vacuum pump, the vacuum pump is prevented from generating larger temperature rise, and the vacuum degree and the service life of the vacuum pump are improved.

Description

Vacuum cooling system is used in tea pigment production Technical Field The application relates to the technical field of vacuum cooling, in particular to a vacuum cooling system for tea pigment production. Background The tea pigment is a mixture of water-soluble pigments formed by continuous oxidation polymerization of polyphenol compounds represented by catechin in tea, and can be used in the fields of food and medicines, and the tea pigment capsule has effects of clearing head and eyes, eliminating phlegm and reducing fat, and can be used for treating dizziness, chest distress and pain, hyperlipidemia, coronary heart disease, angina pectoris, cerebral infarction and other symptoms caused by phlegm stasis. Tea pigment is produced with tea as material and through decoction, extraction, alkalization, concentration, reflux extraction and precipitation. In the process of alkalization concentration, the vacuum degree in the concentration evaporator needs to be reduced so as to reduce the boiling point of tea juice in the concentration evaporator, but in the process of maintaining the vacuum degree in the concentration evaporator, high-temperature steam in the concentration evaporator is directly pumped into the vacuum pump, so that the vacuum pump generates larger temperature rise, and the vacuum degree and the service life of the vacuum pump are influenced.
