Asparagus tea, I believe that many people have drunk Pu'er tea, black tea, green tea, Iron Goddess of Mercy and so on, but few people should know asparagus tea. Asparagus tea is fresh asparagus as raw materials, through today's science and technology cut without adding any substances manufactured. Asparagus tea practice detailed steps: 1, process, raw material picking - drying - roller killing - air cooling - hot air second killing - kneading - billet spreading, cooling - hot air drying - finished products - packaging. 2, the main points of the operation, (1) raw material picking: the length of 3 ~ 87.5px, picking the length of the requirements of the neatness. (2) spreading and drying: the picking of raw materials to concentrate, spreading and spreading in the ventilation and convection conditions in a good room, usually with bamboo mats or plastic film for the ground padding, drying the surface moisture in a natural state. (3) drum killing: the raw materials will be placed in the drying drum killing machine for the first killing, drum killing temperature control at 85 ~ 95 ℃. (4) wind cool: under the material at the mouth of the system set up to blowing facilities, material, wind constantly, under the end of the material, continue to blow 3 ~ 5min. (5) hot air second kill: the air-cooled raw materials placed in the hot-air baking machine sieve plate, through the 200 ~ 250 ℃ hot air, baking and shaking baked until the raw materials 7 ~ 8% dry, to complete the second kill. (6) Kneading: In the gabion plate, hold the raw materials with both hands after moderate heat dissipation, push forward and knead, use the wrist force for moderate pressure, knead until there is a slight overflow of stem juice, moistening to the degree. (7)Spreading and cooling: after kneading the wet blanks, shake them out in time and spread them evenly in the gabion plate, so that they can continue to emit heat and part of the moisture in the natural state, so that the moisture in the stems and stalks can be dispersed evenly for drying. (8) Hot air drying: the same as the hot air second killing operation is consistent, when a light pinch with the hand that is broken, it can be stopped. (9) Finished product: finished product moisture content of 8 to 10%, yield in 18 to 20%. (10) Packaging: the heat dissipation temperature at about 45 ℃ immediately packaged to prevent the finished product moisture absorption, easy to cause mold. Well, the above is the asparagus tea manufacturing all and very detailed process, interested friends can personally try. We all know that every kind of tea has its specific effects and functions, and asparagus tea is no exception. Firstly, it has the function of preventing cancer as other teas, eliminating cancer cells, preventing the proliferation of cancer cells from a biological point of view, and guiding the normal growth of cells; secondly, it reduces blood pressure, blood lipids and cholesterol and so on, so as to achieve the effect of treating heart and blood vessel diseases; thirdly, asparagus tea affects the immune system; fourthly, drinking asparagus tea has the effect of anti-ageing.
