Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with specific embodiments.

[0011] An integrated processing method for primary refining of machine-harvested fresh-leaf green crushed tea, in which raw tea is directly processed after primary processing (primary processing: fresh leaves→spreading→greening→kneading and cutting→dispersing→primary drying→sufficient drying) It is transported to the round sieve machine for subsequent refining process (refining process: raw tea→round sieve→electrostatic stem sorting), that is, firstly, the fresh leaves of the machine-picked tea tree are spread and greened, and then kneaded, cut, broken up and disassembled Afterwards, it is processed by the initial drying and full drying process, and finally the stable green broken tea product is obtained directly through the round sieve and stem sorting process. It specifically includes the following steps:

[0012] Step 1. Select the fresh leaves of a tea tree w...

Abstract

The invention relates to a primary refining integrated processing method of broken green tea from fresh leaves picked by a machine. The primary refining integrated processing method comprises the following steps of step I, selecting fresh leaves from tea trees on which the tea leaves have one bud and four to five leaves for natural spreading: step II, performing fixation, wherein the moderate standard lies in that the leaves are soft in texture, and green grass smell disappears; step III, performing rolling and cutting, wherein the moderate standard lies in that after rolling and cutting, theleaves are emerald green in color, and the tea stems and leaves are finely-crushed; step IV, performing deblocking, and then performing primary drying; step V, performing sufficient drying, wherein the temperature for sufficient drying is set to 135-145 DEG C, so that the water content of tea semi-finished products is 7% or below; step VI, performing classifying: sieving the broken tea leaves intotea of different grades from four outlets being smaller than 12 meshes, being 12-40 meshes, being 40-60 meshes, and being greater than 60 meshes, wherein the broken tea being smaller than 12 meshes and the broken tea being greater than 60 meshes are used as byproducts for storage; and step VII, performing stem sorting: separately obtaining a quality product 1, a quality product 2, a correspondingbyproduct 1 and a corresponding byproduct 2, and separately storing the quality products and the byproducts. The primary refining integrated processing is realized, so that quality products of the broken green tea of 2 different grades are obtained, and stable products are obtained.

Description

technical field [0001] The invention relates to a processing method, more specifically to an integrated processing method for primary refining of machine-harvested fresh-leaf green crushed tea, which belongs to the technical field of tea processing. Background technique [0002] Broken green tea is an important export tea in my country. It is grainy (sandy) in shape, green in color, bright green in soup color, and rich in taste. It is mainly used to produce teabags or provide raw materials for deep processing of tea. However, the current green crushed tea production process is cumbersome, labor-intensive, processing costs are high, product quality is unstable, and cannot meet the needs of large-scale production. Therefore, there is an urgent need to develop a simplified processing method for green crushed tea to reduce costs in order to obtain green crushed tea products with stable quality, which is of great significance for developing domestic and foreign markets and improv...
