Steam type fixation device for tea processing

Abstract

The invention discloses a steam type fixation device for tea processing. The device comprises an evaporation chamber, wherein a plurality of steam guide pipes are connected to the right side of the evaporation chamber, each steam guide pipe is connected with a negative pressure box, the other ends of the steam guide pipes are connected with a steam distributing pipe, an upper distributing port isformed in the upper end of the steam distributing pipe, a lower distributing port is formed in the lower end of the steam distributing pipe, the upper distributing port is connected with an upper steam through pipe, the lower distributing port is connected with a lower steam through pipe, the upper steam through pipe and the lower steam through pipe are jointly connected to a fixation assembly, aliquid water recovery box used for collecting condensed steam is arranged at the lower end of the fixation assembly, the right side of the liquid water recovery box is connected with a liquid water cleaner, and the liquid water cleaner is connected with the evaporation chamber through a circulation pipe. The fixation temperature and the fixation time are strictly controlled, a conventional bottom-up steam fixation method is changed into a fixation means for performing wide spraying from the middle to two sides, the steam radiation range is wider, and the quality is higher.

Description

technical field [0001] The invention relates to the technical field of tea processing equipment, in particular to a steam-type degreening device for tea processing. Background technique [0002] Finishing is one of the key processes in tea making technology. "Green" refers to fresh leaves. As the name suggests, killing green is to destroy the tissues of fresh leaves. In the greening process, high temperature measures are taken to rapidly transform the contents of fresh leaves. Fixing will not only destroy the activity of the enzyme, but also convert the content into the basis of the unique quality of various teas. Tea leaves contain substances called enzymes. Enzyme is a biomacromolecule with biocatalytic function, and it is a kind of biocatalyst, which can speed up or slow down the speed of biochemical reaction, but does not change the direction and product of the reaction. Most enzymes are composed of proteins (a few are RNA), and their activity is easily affected by f...

AI Technical Summary

Problems solved by technology

[0006] (1) The traditional steam-type de-enzyming device for tea processing is mostly a method of fixed-timing steam suffocation of tea leaves. This method is difficult to strictly control important parameters such as temperature, de-enzyming time, and heat size, and the amount of tea leaves obtained at one time is very small. , can not meet the needs of large-scale industrial production, high efficiency, high success rate to complete the process

[0007] (2) The existing steam-type de-enzyming device for tea processing uses belt transmission in the de-enzyming process, which not only greatly improves the efficiency of de-enzyming but also strictly controls the de-enzyming time according to the belt speed, but this method is difficult to solve for the follow-up treatment of water vapor at first, and secondly Steam is generally emitted at the bottom, and it will be blocked by the belt during the steam rising process, resulting in a waste of steam energy. Finally, the existing finishing methods cannot spread the tea evenly in advance, resulting in large limitations and incomplete finishing, which cannot guarantee the quality of finishing.
