Problems solved by technology

Withering is a key process in the process of tea processing. With the conventional withering technology, many teas have problems such as the bottom of the tea leaves are not fresh, the color is not green, and the taste is not fresh after the finished product is produced. Moreover, the conventional withering method longer time

Embodiment Construction

[0013] The main process of making tea is: picking—withering—killing—kneading—shaping—drying. The conventional withering method is to spread the picked leaves evenly indoors and let them stand for a period of time, so that the water in the tea leaves will slowly evaporate and reduce. It is soft and easy to knead, and at the same time, the tea leaves will gradually undergo chemical changes in the process of water loss. But this method takes a long time, and it will affect the freshness and color of the tea.

[0014] Through years of practical experience, technicians adopt refrigeration technology, install condensers in withering tanks or withering chambers, use internationally imported frequency conversion compressors for refrigeration, and use international environmental protection R410 refrigerants to evenly send cold air to the green surface through fans , through the low-temperature withering technology, the damage to the chlorophyll of tea greens by the conventional witheri...

Abstract

The invention relates to a low-temperature withering device for tea leaves, which mainly comprises a shell, a CPU (central processing unit) control system, a compressor, a capillary tube, a condenser, a radiator, electron temperature probes and a fan. The shell of the whole withering device is of a cabinet type structure; 4-6 layers of interlayers are arranged at the upper part of the shell and are used for placing the tea leaves; the electron temperature probes are uniformly arranged on the interlayers and are used for detecting the temperature of each interlayer; the compressor, the capillary tube, the condenser, the radiator and the fan are arranged at the lower part of the shell; the condenser is positioned above the radiator; the capillary tube is positioned between the condenser and the radiator; and the temperature in the whole withering device is controlled at 8 DEG C. According to the low-temperature withering device provided by the invention, the time for the tea leaves to wither is greatly shortened, the efficiency for making tea is improved, the risk of nonuniform quality of high-end brand-name tea is reduced, the quality of the tea leaves is improved, and the competition of the tea leaves in the market is enhanced.

Description

technical field [0001] The invention belongs to the field of tea product processing, and in particular relates to a low-temperature withering method for dark green tea. [0002] Background technique [0003] In the tea product industry, freshly picked leaves from the tea garden are used as raw materials for processing finished tea. Withering is a key process in the process of tea processing. With conventional withering technology, many tea leaves have problems such as the bottom of the tea leaves are not fresh, the color is not green, and the taste is not fresh after the finished product is produced. Moreover, the conventional withering method A long time. [0004] Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a new type of withering equipment, and the freshness and color of the tea leaves withered by the equipment are very good. [0006] A low-temperature withering equipment for tea greens, mainly compris...
