What are the main process parameters for instant flower tea?
(1) Countercurrent extraction: green tea and deionized water are subjected to countercurrent extraction at a tea-to-water ratio of 1:15 for 15 min, with the extraction water temperature at 90°C. In commonly used instant tea production processes, the extraction operation is carried out intermittently, making it difficult to complete the tasks of discharging and separating the tea liquor from the tea residue within 15 min, which causes the tea leaves to remain too long in the high-temperature tea liquor, resulting in large aroma loss, a heavily bitter and astringent tea liquor with a strong stewed, over-cooked taste, and greatly reduced instant tea quality. The developed horizontal continuous countercurrent extractor, in order to reduce axial mixing of tea and water within the extractor and weaken back-mixing, adopts three horizontal extractors connected in series, achieving effective isolation of inter-stage back-mixing. The tea liquor and tea residue are continuously discharged from both ends of the extraction system, and the countercurrent extraction time can be controlled at about 15 min by adjusting the flow rates of tea and water. Compared with intermittent extraction, aroma loss is small and the taste of the tea liquor is noticeably improved.

A detailed explanation of the processing flow of Xizi Liren tea, explained in one article
Xizi Liren tea is produced in the area of the eastern slope of Dongbai Mountain in the southeast and the Longmen Mountain range in the western mountainous area of Zhuji City, the hometown of Xishi. The main peak of Dongbai Mountain, Taibai Peak, and the main peak of Longmen Mountain, Sanjie Peak, both have elevations higher than 1000 m. Here, mountains surround the area, peaks rise one after another, appearing and disappearing in undulation, with lush trees, year-round shrouding clouds and mist, and ever-flowing clear waters. The entire climate environment forms the high-mountain wonder of "fog everywhere in the morning and evening on clear days, clouds all over the mountain on rainy days." Tea trees grow for a long time under diffused light and are nourished by rain and dew, so the buds and leaves are plump and tender and rich in internal substances, which lays a good material foundation for the unique quality of Xizi Liren tea.

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

Detailed Explanation of the Processing Technique Flow of Pu'er Tea
When it comes to the unique quality characteristics of Pu'er tea, they are fundamentally determined by two aspects. First, the tea leaves used to make Pu'er tea must be Yunnan large-leaf tea. This is because the content of tea polyphenols, catechins, caffeine, theanine and water extracts in Yunnan large-leaf tea trees is generally higher than in medium- and small-leaf tea trees. Second, the special production technique of Pu'er tea. The production technique of Pu'er tea is divided into traditional technique and modern technique. Regarding the traditional technique of Pu'er tea, the famous Pu'er tea expert and professor Zou Hongjie of Yunnan Agricultural University states in the book "Yunnan Pu'er Tea" that

Detailed Explanation of Longjing Tea Processing Techniques and Production Flow
Longjing tea is a tea category unique to Zhejiang. Besides the West Lake Longjing tea area, there is also a small amount of production in Chun'an and Lin'an. In 1960, production of a portion of high-grade Longjing tea was expanded in some areas of Fuyang, Xiaoshan, and Yuhang, with an annual output of 250 tons. In 1965, in order to maintain the reputation of the famous Longjing tea, production was limited to the West Lake Longjing tea area in Hangzhou, the tea produced in the Wenjiayan and Changhe areas of Xiaoshan was renamed "Xianghu Qiqiang," and tea produced in all other areas was no longer regarded as Longjing tea, with output correspondingly reduced.

Detailed explanation of peach juice processing technology and flow
(1) Process flow: feeding → cleaning → cutting into halves → pitting → soaking → pre-boiling → pulping → blending → deaeration → homogenization → sterilization → filling → sealing → cooling → wiping bottles → labeling → quality inspection → boxing → warehousing (2) Process specifications (1) Raw materials: Select canning peach varieties for processing, with large size, small pit, clingstone, white or yellow flesh, and a relatively high degree of ripeness to highlight the peach flavor. Remove diseased, insect-damaged, bruised and rotten fruit, then wash. When washing, pay attention to brushing off the peach fuzz with a brush. If pesticides are present, add dilute hydrochloric acid to
