Description
Technical Field
The invention relates to a gross fire and full fire automatic device for a white tea production process, belonging to the technical field of white tea processing equipment.
Background
White tea, belonging to micro-fermented tea, is a special treasure in Chinese tea. The finished tea is mostly bud heads, and is full of pekoe, so that the finished tea is named after the silver is like snow. One of six Chinese teas. The white tea is processed by drying in the sun or by slow fire without deactivating enzymes or rolling, and has the quality characteristics of complete bud, complete body, fragrant and fresh taste, yellow green and clear soup color, light taste and sweet taste. The main production areas of white tea are Fujian tripod, political harmony, Cudrania tricuspidata, Wuhan New Zhou old street, Banxia Tianshan, Songxi, Jianyang, Yunnan Jinggu, and the like. The basic process comprises the procedures of withering, baking (or drying in the shade), picking, annealing and the like. The Yunnan white tea process mainly dries the green, and the dried green tea has the advantage that the taste keeps the original faint scent of tea leaves. The preparation process of the manual white tea comprises gross fire and full fire. Gross fire: the baking tool of the manual white tea is mainly a bamboo baking cage, and the baked raw material is pine charcoal. When the wool is baked, the tea leaves are uniformly spread, the temperature of the baking cage is about 90 ℃, and the tea leaves are turned over at regular time. The appearance needs to be finished again while drying, and the aroma of the tea leaves is improved. And (5) when the tea leaves are dried to eighty percent, standing for cooling, and then re-drying in a cage. And (3) full fire: the tea leaves are subjected to primary baking, the temperature is mainly low and is not more than 70 degrees, the dryness of the tea leaves reaches about nine tenths of a year after the tea leaves are subjected to gross fire and repeated spreading, the purpose of full fire is to reduce the water content of the tea leaves to be less than 5 percent, and the baking time can be prolonged. And when the tea leaves are sufficiently dry, the tea leaves can be baked and spread, and then are packaged, stored and sold. In view of the above problems, it is an urgent need to provide an apparatus capable of automatically performing a gross fire and a sufficient fire.
