The meaning of tea deep processing

The deep processing of tea refers to using fresh tea leaves and finished tea leaves as raw materials, or using tea leaves, waste products and scraps from tea factories as raw materials, and using corresponding tea processing machines to produce tea-containing products. Tea-containing products may be based on tea or other substances.

First, make full use of tea resources. A lot of low-grade tea, tea scraps, and tea waste have no direct market outlet, and there are a lot of utilizable resources in them. Deep processing of them can make full use of these resources to benefit mankind, and companies can also gain economic benefits from them. .

The second is to enrich market products. Tea is of course a very good thing, but people are no longer satisfied with the product form of tea as just “dried leaves”. Matcha powder ground with a stone matcha tea mill machine is loved by young people, and people need enriched tea products.

The third is to develop new functions. Many functions or effects of tea cannot be utilized in traditional brewing methods. By further processing tea, these functions can be utilized in a targeted and purposeful manner. At the same time, it also cooperates with other substances in deep processing to play a greater role.

Tea deep processing technology can generally be divided into four aspects or categories, which are: mechanical processing, chemical and biochemical processing, physical processing, and comprehensive technical processing.

Mechanical processing of tea: This refers to a processing method that does not change the basic essence of tea. Its characteristic is that it only changes the external form of tea, such as appearance, shape, size, so as to facilitate storage, brewing, compliance with health standards, beauty, etc. Tea bags are typical products processed by tea packaging machines. ​

Chemical and biochemical processing: refers to the use of chemical or biochemical methods to process products with certain functionalities. Its characteristic is to separate and purify certain special ingredients in tea from tea raw materials for beneficial use. Such as tea pigment series, vitamin series, antiseptics and so on. ​

Physical processing of tea: Typical products include instant tea produced by powder packaging machines, canned tea (ready-to-drink tea), and bubble tea (modulated tea). This changes the shape of the tea leaves, and the finished product is no longer in the form of “leaf”.

Comprehensive technological processing of tea: refers to the comprehensive use of the above-mentioned technologies to make tea-containing products. The current technical means mainly include: tea drug processing, tea food processing, tea fermentation engineering, etc.
