Reduced vaporization device for preparing tea extract

Abstract

The invention provides a reduced vaporization device for preparing tea extract. The device comprises a heat furnace inside which is provided with a heating coil, and also comprises a main evaporator inner shell, and a jacket and an auxiliary evaporator shell which are fixedly connected with the main evaporator inner shell; a water-containing tea extract to be treated is put into the main evaporator inner shell, and the main evaporator inner shell is airtightly connected with a main evaporator cap; the jacket is fixedly connected with a heat medium reflux opening and a heat medium inlet; a vapor outlet pipe is fixedly connected on the main evaporator inner shell; the vapor outlet pipe is fixedly connected with a main evaporator steam valve; the auxiliary evaporator shell is filled with an adsorptive substance, and is airtightly connected with an auxiliary evaporator cap; an auxiliary evaporator vent connecting pipe is fixedly connected on the auxiliary evaporator cap; and the auxiliaryevaporator vent connecting pipe is communicated with an auxiliary evaporator vent valve. Negative pressure is generated by adopting the adsorption method, so that negative pressure for negative pressure evaporation can be obtained without electricity, and the overcooking phenomenon occurring in the tea extract manufacturing process can be avoided.

Description

technical field [0001] The invention relates to a tea paste production device, in particular to a decompression evaporation device for preparing tea paste, belonging to the technical field of tea machinery. Background technique [0002] Tea paste is a solid instant tea obtained by processing and fermenting Yunnan's unique large-leaf tree tea leaves, separating the fibrous substances in the tea leaves from the tea juice in a special way, and re-evaporating the obtained tea juice. The traditional tea paste production is the boiling method. During the boiling process, the tea juice may burn, especially in the later stage of boiling, which makes the production process difficult to control. Aiming at the problems existing in the traditional technology, some enterprises and scientific research institutions have developed the technology of spray-drying to prepare tea paste and the technology of low-temperature extraction to prepare tea paste. These new technologies for preparing ...

AI Technical Summary

Problems solved by technology

These new technologies for preparing tea paste can solve the problem of sticking pots, but they have the following disadvantages: more equipment is involved, and the investment in equipment is larger; it must be driven by electricity to run, which limits the use of this type of technology in mountainous areas without electricity supply , and it is not conducive to popularization among farmers with limited financial affordability
