Production method of concentrated tea juice

Abstract

The invention discloses a production method of concentrated tea juice. The method comprises the following steps of: A, putting tea leaves into an enclosed extracting and concentrating tank, continuously filling purified water into the tank through a flow pump to obtain tea concentrated solution and continuously discharging the tea concentrated solution from the other end of the extracting and concentrating tank; B, cooling the tea concentrated solution and feeding the cooled tea concentrated solution into centrifugal separation equipment for separating; and C, performing instantaneous sterilization at a super high temperature after separation and performing sterile filling after cooling so as to obtain the concentrated tea juice. The tea leaves are soaked in continuously flowing purified water, so that high leaching rate is achieved with a small amount of water; when the leaching rate is fixed, high-concentration concentrated solution is obtained, subsequence process cost is lowered, processing time is shortened, tea quality is enhanced and fragrance is collected and thickened; and compared with the conventional extraction method, the method can effectively reduce energy consumption and resource waste and is accordant with the development direction of the national low-carbon economy.

Description

technical field [0001] The invention relates to the processing and production of tea leaves, in particular to a production method of concentrated tea juice. Background technique [0002] The existing concentrated tea juice production technology uses a method similar to ordinary tea making, that is, soaking tea leaves with fixed water to obtain concentrated tea juice. This traditional production method uses reverse osmosis concentration, vacuum concentration, etc. Just can make tea juice reach higher concentration, and need consume a large amount of water, have not only improved production cost, also do not meet the requirement of energy saving and environmental protection. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the traditional concentrated tea juice production technology and propose a new production method to achieve the purpose of energy saving, emission reduction and cost reduction. [0004] The technic...

[0002] The existing concentrated tea juice production technology uses a method similar to ordinary tea making, that is, soaking tea leaves with fixed water to obtain concentrated tea juice. This traditional production method uses reverse osmosis concentration, vacuum concentration, etc. In order to make the tea juice reach a higher concentration, and it needs to consume a lot of water, which not only increases the production cost, but also does not meet the requirements of energy saving and environmental protection
