China is a big tea country and has a habit of drinking tea since ancient times. Green tea belongs to non-fermented tea and is made by the process of fixing, rubbing, and drying. Its quality characteristics are “three greens†(green, soup green, green leaf), high fragrance, fresh taste, and more. It retains natural substances in fresh leaves, such as tea polyphenols, amino acids, chlorophyll, and vitamins. The basic process of green tea processing is: picking → spreading → fixing → rubbing → drying. After the green leaves of fresh green tea are returned to the factory, they should be spread on clean utensils with a thickness of 7-10 cm. It is appropriate to spread the leaves for 6-12 hours and the middle leaves are properly turned over. When the moisture content of the fresh leaves is 68% to 70%, when the leaf quality becomes soft and fragrance is released, the fixation phase can be entered. Fixing is the key process in the processing of green tea. It takes high-temperature measures to distribute leaf water, inactivate enzyme activity, and cause certain changes in the contents of fresh leaves to form the quality characteristics of green tea. The purpose of fixation is to utilize the activity of high-temperature deactivating enzymes to maintain the color and flavor of the tea. The characteristics of killing moderateness are that the leaf is soft and slightly sticky, clasped tightly, slightly elastic, and the tender stems are folded continuously, the old leaves are cooked without coke, the surface is dull, there is a slight fragrance, and the weight loss of fresh leaves is 30%- 40%, to achieve the requirements of cooked, transparent, uniform. After fixing the leaves, it is necessary to immediately cool off the leaves. It is best to use a fan to cool it, so that it can quickly distribute water, reduce the temperature of the leaf, and prevent yellowing of the leaf color and the generation of water boring taste. Microwave fixation is a new technology developed in recent years. It utilizes the characteristics of rapid microwave heating to increase the temperature of green tea to a temperature at which the active oxidase is inactivated in a short time. It can be completed in 3-5 minutes. The tea finished by microwaves has a green color, good shape, fresh tea, and environmental protection and energy saving, which is in line with the current development needs. The order of a customer in Fujian is our tunnel-lined microwave microwave killing device, which is composed of four independent microwave heating boxes, plus a microwave suppression system, a cooling system, a dehumidification and heat removal system, etc. The operation is flexible. At the same time, the observation door is arranged on the side of the cabinet. The production time is convenient for observation and cleaning. The equipment feeds, kills and discharges the material at one go. It is simple and clear. Cooperation with Fujian customers is another successful case of cooperation between our company and the tea industry. It also reflects that our equipment has had a certain influence in the tea industry. In the new year, "Qi Xie" is also accompanied by the bell is one year old, but this shows that our technology is more mature and the equipment is more welcomed and trusted by customers. On the occasion of the New Year, Qi Xie Microwave wished everyone a prosperous business in the new year.
