Detailed explanation of the simple production processes for various tea beverages
Selenium-enriched tea beverage process flow: tea leaves → extraction → coarse filtration → fine filtration → blending → ultra-high temperature sterilization → filling → high-pressure sterilization (115°C, 20 min); ultra-high temperature sterilization → aseptic filling → labeling, inspection. Bottled black tea beverage process flow: black tea → extraction → precision filtration → blending → heating → filling → sealing → sterilization → finished product. Canned oolong tea beverage process flow: tea leaf roasting → extraction → filtration → blending → heating → canning → nitrogen flushing → sealing → sterilization → cooling → inspection → finished product. Bottled black tea beverage process flow

How Is Asparagus Tea Made? A Complete Guide to the Production Process
1. Process flow: raw material picking - spreading to air-dry - drum fixation - air cooling - second hot-air fixation - rolling - spreading the batch and cooling - hot-air drying - finished product - packaging. 2. Key operating points: 1. Raw material picking: length 3-3.5 cm, and the cut lengths must be highly uniform. 2. Spreading to air-dry: gather the picked raw material and spread it out flat in a room with good ventilation and air convection; generally use bamboo mats or plastic film as a ground liner, and let the surface moisture dry off under natural conditions. 3. Drum fixation: place the spread

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,

Detailed Explanation of the Production Process of Lingtou Dancong Tea
The "honey rhyme" of Lingtou Dancong tea is formed during the processing technique, and the main key processes are leaf shaking and roasting; the two are very important for forming and developing the "honey rhyme" characteristics, complementing each other and enhancing each other. (1) Leaf shaking is the key process for the formation and development of the "honey rhyme." After sun withering is completed, the sun-withered leaves give off a distinctive varietal aroma. As the normal number of leaf-shaking rounds increases, the leaf-shaking aroma gradually turns from light to strong, the grassy smell fades, and the floral-honey sweet fragrance emerges. Especially after fixation, the fixed leaves have a clear, mellow
