Flat tea shaping device and method

Abstract

The invention discloses a flat tea shaping device and a method, and aims to overcome the defects that fried finished tea is bifurcated in appearance, tea strips are not straight and light, and the quality requirements of flattening, uniform and straight gathering and heavy compaction cannot be met. The flat tea shaping device comprises an arc-shaped tea frying pan, a main shaft, a scraping rod assembly and a stir-frying assembly, the stir-frying assembly comprises a left stir-frying hand, a middle stir-frying hand and a right stir-frying hand, the left stir-frying hand and the right stir-frying hand are hinged to the left side and the right side of the middle stir-frying hand respectively, the middle stir-frying hand is fixedly connected with the main shaft, a left piston cylinder and a right piston cylinder are hinged to the main shaft, a left piston cylinder telescopic rod is hinged to the left stir-frying hand, a right piston cylinder telescopic rod is hinged to the right stir-frying hand; the scraping rod assembly is fixedly connected with the main shaft, a scraping plate is arranged on the scraping rod assembly, the lower surface of the middle stir-frying hand is of an arc-shaped structure matched with the bottom surface of the tea frying pan, and the middle stir-frying hand is close to the bottom surface of the tea frying pan. Finished tea strips after stir-frying are straight and meet the quality requirements of being flat, even, straight, folded and heavy.

Description

technical field [0001] The present invention relates to a kind of tea processing equipment, more specifically, it relates to a flat tea shaping device and method. Background technique [0002] The frying of flat tea (such as Longjing tea in Zhejiang) has traditionally been done by hand in an iron pot similar to a hemisphere. In order to improve production efficiency, more and more manufacturers use machinery to fry and process flat tea. The most representative equipment is the long plate flat tea frying machine. Made, covered with cotton cloth and heat-resistant cloth—to give the surface a certain softness to prevent crushing the tea leaves) exert a certain pressure on the tea leaves in the "U"-shaped pot to make the tea leaves reach a "flat" shape. During the processing, it was found that when the grade of fresh leaves is high, such as single bud or one bud and one leaf, the "flatness" and "straightness" of the processed finished tea can meet the appearance quality require...

Problems solved by technology

During the processing, it was found that when the grade of fresh leaves is high, such as single bud or one bud and one leaf, the "flatness" and "straightness" of the processed finished tea can meet the appearance quality requirements of the corresponding grade of tea, while the middle and low grades Fresh leaves (fresh leaf raw materials are generally two or three leaves in one bud, three or four leaves in one bud), the processed finished tea has a bifurcated appearance, showing the shape of "chicken feet", and the tea sticks are not straight and light, the main reason is that the The equipment has no "organization" function, resulting in that the finished tea cannot meet the quality requirements of being flat, straight and straight, and heavy
