Clean tea production process

Abstract

The invention discloses a clean tea production process. The production process comprises the following steps: rotationally rinsing, spray washing, rotationally whirling, drying with cold air, spreading out, grading, deenzyming, primarily winnowing, spreading for drying in the air, primarily rolling, frying at constant temperature in the way of electric heating, spreading out, rolling, winnowing, blending, piling, completely baking, preparing into finish products, inspecting and warehousing. The cleaning process and primarily winnowing processes are added, and the external impurities can be removed; electric-heating constant-temperature frying is adopted to replace the traditional primarily baking process, thus the tea can be heated uniformly and can be prevented from being polluted by other heating materials; dried-up tea dust or carbonized tea dust can not be generated; the tea is held with containers when transferred among different processes; dust and residues are removed in each process in production so that the tea can not be polluted and can not generate pollution impurities in the processing process; thus the purpose of clean tea production is achieved; and the tea does notneed to be washed when brewed, thus greatly improving the utilization of the nutritive substances of the tea.

Description

technical field [0001] The invention belongs to a production process of tea, in particular to a clean production process of tea. technical background [0002] Tea is a necessity in our life. The first procedure we usually drink tea is "washing tea". Impurities wash away. However, in order to show the quality of the tea leaves, part of the nutrients in the fresh tea leaves are spilled and exposed on the surface of the tea sticks during processing. When the tea leaves are dried, the spilled nutrients such as proteins, amino acids, and tea polyphenols are attached in a crystalline state. On the surface of tea sticks, these substances are water-soluble substances. Once they come into contact with hot water, they will dissolve in large quantities in water within a few seconds. Therefore, although washing tea washes away impurities, it also washes out a lot of nutrients. In order to solve this problem, some clean tea production technologies have begun to appear, such as "Tea In...
