Processing method of machine-made sophora japonica bud stir-fried tea

Abstract

The invention belongs to the technical field of tea preparation products, and particularly relates to a processing method of machine-made sophora japonica bud stir-fried tea. The processing method ofmachine-made sophora japonica bud stir-fried tea sequentially comprises the working procedures of performing picking, performing fixation, performing drying, performing stir-frying, performing cooling, performing detection, performing screening, performing color sorting and performing packaging, wherein the working procedure of fixation comprises the specific steps of stacking sophora japonica buds according to the thickness being 4-6cm, performing steaming, and after water is boiled over, continuing performing steaming for 15-20min; the working procedure of stir-frying comprises the specificsteps of performing uniform heating to 122-128 DEG C from room temperature under the condition that the stir-frying quantity is 30-35kg / time and the stir-frying rotational speed is 380-410r / min, wherein the stir-frying time is 13-16min, adding a steviol glycoside solution to the sophora japonica buds, and then continuing performing stir-frying at 122-128 DEG C for 5-7min; and the working procedureof screening comprises specific steps of putting the sophora japonica buds on a double-layer vibration screening machine, and performing screening with an 80-100-mesh sieve twice. Through the adoption of the method, industrial production can be realized; the made sophora japonica bud stir-fried tea is high in sense organ grade, and the tea soup is clear and golden, has scorch aroma in mouth feel,and does not have any bitterness or peculiar smell.

Description

technical field [0001] The invention belongs to the technical field of tea preparations, and in particular relates to a tea processing method made by frying Sophora japonica.
