The microwave tea-killing machine can keep the content of amino acid and vitamin C in green tea more, make the processed tea more verdant in color, natural stretch in appearance, beautiful and improve the quality of tea. The results showed that the quality of tea processed by microwave and stir-frying was good, but the time of microwave was short (1/8 of stir-frying time) and could be carried out continuously.
and steam-sterilized tea has almost no weight loss and part of chlorophyll is destroyed because of the high moisture content of steam and the influence of high temperature on the outer layer of raw materials. The nutrients in raw materials are partially lost with the condensate water and the quality is not ideal. The advantage of microwave green-killing is fast, efficient, and short time, less loss of organic matter in tea, the quality of tea is guaranteed, and tea will not produce astringent taste because of too long production time.
Microwave tea-killing machine is simple to operate and easy to control. It can kill tea thoroughly and evenly. At the same time, it can achieve low-temperature green-killing with the shortest time and relatively low energy consumption cost. In recent years, with the upgrading of the main core components of microwave equipment technology, the price has been declining, and the investment of equipment has also been greatly reduced. There is no doubt that microwave tea-killing machine is successful. In order to select the main technology of tea green-killing in the market, it is generally necessary to remove about 20% - 30% of the water from the green-killing part. The green-killing should ensure the airtight space of microwave and play the role of moisturizing, so that after the green-killing, the infrared drying will not change color.
means that after tea enters microwave strong> tea strong> Green killer heat is maintained, moisture will not evaporate, and convection and oxidation will not occur in the air, playing the effect of “ steaming & rdquo; The defoliation law of magnetron is that every KW magnetron can evaporate 1 KG of water per hour. For example, if you need to process 100 KG tea every hour, for example, to remove 20% moisture from the green, you need a 20 KW microwave equipment.
