Detailed Explanation of the Processing Technology and Production Methods of Crude Tea
The crude tea processing procedure is a process of repeated operations of sifting, cutting, selecting, picking, and pan-firing. The ordering of each process, the number of repetitions, and so on must all follow certain principles. 1. Sift first, then winnow. Winnowing mainly separates the light and heavy tea leaves and distinguishes superior from inferior quality. Only when the tea material is the same in length, size, and thickness can the light and heavy be separated most effectively and superior from inferior quality be distinguished clearly. Therefore, before winnowing, sifting must be carried out first. 2. Re-fire first, then cut. Generally, the head tea on the sieve surface

Refined Processing Flow and Technical Key Points of Eyebrow Tea
Its product shape resembles an eyebrow, hence it is called eyebrow tea. Eyebrow tea is one of the bulk export teas of Zhejiang green tea. Eyebrow tea is made from long pan-fired green tea (Hangzhou pan-fired green tea, Suichang pan-fired green tea, Wenzhou pan-fired green tea) as raw material, refined and blended. Its processing technique is: blending and grading of raw materials, taking material from five routes: the body itself, round body, long body, sub-grade bits, and stem and fiber. The processing operations are divided into re-firing and rolling of crude tea, sorting and sifting, beating and sifting, shaking and sifting, strip cutting, picking and removing, fanning, supplementary firing and coloring, clearing wind and cutting off dust; the semi-finished product is piled and stored in the warehouse, then blended according to the sample, evenly piled and packed into boxes to become export eyebrow tea. Its product specifications are based on

What are the steps in the production process of yellow tea?
The quality characteristic of yellow tea is yellow liquor and yellow leaves. The production method is mainly characterized by the menhuang (smothering/yellowing) process, which uses high temperature fixation to destroy enzyme activity. The subsequent oxidation of polyphenols is caused by the action of damp heat and produces some colored substances. When the degree of color change is relatively light, it is yellow tea; when the degree is heavier, it forms dark tea. Its typical process flow is fixation, menhuang (smothering/yellowing), and drying. Rolling is not an essential process for yellow tea. (1) Fixation. Through fixation, yellow tea destroys enzyme activity, evaporates part of the water,

A Detailed Guide to the Harvesting Standards and Processing Methods for Goji Berries
1. Harvesting requirements: Medicinal goji berries (Lycium barbarum) ripen successively from June to November and should be harvested at the right time. They can be picked when the fruit turns from green to red or orange-red and the fruit stalk and flesh become slightly soft. If picked too early, the fruit is not plump and its color after drying is dull; if picked too late, the sugar content is too high and the fruit easily drops off, becoming dark purplish-black after sun-drying or oven-drying (commonly known as oil seeds) and losing its commercial value. Picking is best done after 10 a.m. on a clear day. Never pick fruit after rain or when covered with dew. Handle it gently when picking and remove it together with the fruit stalk. Otherwise, the juice will flow out and affect its internal quality.
