Embodiment 1

[0031] A method for cleaning green tea leaves, comprising steps:

[0032] 1) The soaking step is as follows: add 18 grams of Biazyme per 500 liters of water, pour 40 kilograms of tea leaves, soak for 0.5 hours, then clean the tea leaves, and then collect them in barrels;

[0033] 2) Drying step Put the tea leaves in the drying equipment and dry them;

[0034] 3) air-drying step utilizes high-speed air-drying equipment to carry out air-drying with the dried tea leaves;

[0035] 4) Drying step puts the air-dried tea leaves on the shelves and spreads them to dry;

[0036] 5) The above-mentioned dried tea leaves are subjected to subsequent processing through a greening process.

[0037] The cleaning of the tea leaves is done by spraying.

[0038] The rotational speed of the drying equipment is 1100r / min.

[0039] The drying step is to put the air-dried tea leaves on the shelves and spread them thinly, and blow them dry with a fan.

Embodiment 2

[0041] A method for cleaning green tea leaves, comprising steps:

[0042] 1) The soaking step is as follows: add 20 grams of Biazyme per 550 liters of water, pour 45 kilograms of tea leaves, soak for 1 hour, then clean the tea leaves, and then collect them in barrels;

[0043] 2) Drying step Put the tea leaves in the drying equipment and dry them;

[0044] 3) air-drying step utilizes high-speed air-drying equipment to carry out air-drying with the dried tea leaves;

[0045] 4) Drying step puts the air-dried tea leaves on the shelves and spreads them to dry;

[0046] 5) The above-mentioned dried tea leaves are subjected to subsequent processing through a greening process.

[0047] The cleaning of the tea leaves is done by spraying.

[0048] The rotational speed of the drying equipment is 1200r / min.

[0049] The drying step is to put the air-dried tea leaves on the shelves and spread them thinly, and blow them dry with a fan.

Embodiment 3

[0051] A method for cleaning green tea leaves, comprising steps:

[0052] 1) The soaking step is as follows: add 22 grams of Biazyme per 600 liters of water, pour 50 kilograms of tea leaves, soak for 1.5 hours, then clean the tea leaves, and then collect them in barrels;

[0053] 2) Drying step Put the tea leaves in the drying equipment and dry them;

[0054] 3) air-drying step utilizes high-speed air-drying equipment to carry out air-drying with the dried tea leaves;

[0055] 4) Drying step puts the air-dried tea leaves on the shelves and spreads them to dry;

[0056] 5) The above-mentioned dried tea leaves are subjected to subsequent processing through a greening process.

[0057] The cleaning of the tea leaves is done by spraying.

[0058] The rotational speed of the drying equipment is 1300r / min.

[0059] The drying step is to put the air-dried tea leaves on the shelves and spread them thinly, and blow them dry with a fan.

Abstract

The invention discloses a method for cleaning green tealeaves. The method comprises: 1, an impregnation step of adding 18 to 22 grams of organophosphate-degrading enzyme into every 500 to 600 liters of water, pouring 40 to 50 kilograms of tealeaves, impregnating the tealeaves for 0.5 to 1.5 hours, washing the tealeaves, and collecting the tealeaves in a bucket; 2, a spin-drying step of placing the tealeaves into spin-drying equipment for spin-drying; 3, an air-drying step of air-drying the spin-dried tealeaves by using high-speed air-drying equipment; 4, an airing step of spreading the air-dried tealeaves in a thin layer on a shelf for airing; and 5, a step of subsequently processing the aired tealeaves by using a fixation process. The problems of pesticide residues on the surfaces of the tealeaves, dust pollution, heavy metal pollution, harm of remaining ozone to a human body during ozone washing and incapability of decomposing most of pesticides by pure fresh water washing are solved by impregnation, washing and dehydration.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to a method for cleaning green tea leaves. Background technique [0002] The existing green tea processing method is to directly spread the leaves after picking, and then process them again, which does not solve the problems of pesticide residues, dust pollution and heavy metal pollution on the surface of the tea leaves. The current ozone disinfection has a great impact on the flavor of the tea leaves, and the operation High difficulty. Contents of the invention [0003] The invention proposes a method for cleaning green tea leaves, which solves the problems of pesticide residues, dust pollution and heavy metal pollution on the surface of tea leaves in the prior art, and ozone disinfection residual ozone is harmful to the human body. Simple water washing can not decompose most of the pesticides The problem. [0004] Technical scheme of the present inventi...
