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

Black tea → extraction → precision filtration → blending → heating → filling → sealing → sterilization → finished product

Tartary buckwheat tea beverage process flow

Tartary buckwheat → cleaning → steaming → drying → roasting → crushing → extraction → filtration → blending → sterilization → filling → finished product

Lemon honey tea beverage process flow

Black tea leaves → freeze-drying → grinding → soaking → centrifugation → clarification → blending → filtration → flash sterilization → filling and sealing → packaging → finished product

Burdock tea beverage process flow
