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] Based on many years of practical experience, the present invention adopts refrigeration technology, installs a condenser in the withering tank or the withering chamber, uses frequency conversion compressor to refrigerate, adopts international environmental protection R410 refrigerant, and sends the cold air evenly to the green surface through the fan, so that The water in tea green evaporates quickly and becomes soft. The withering method can be adapted to any curre...

Abstract

The invention relates to a method for low-temperature withering tea leaves, which adopts a refrigeration technique, a condenser is installed in a withering chamber, an inverter compressor is utilized for refrigeration, an international environmental protection R410 refrigerant is adopted, a fan is used to blow the cold air uniformly to the surfaces of the tea leaves, so the water of the tea leaves is quickly volatilized, and the tea leaves are softened; the withering chamber takes a standard that equipment with the refrigerating capacity of 2500 watts is configured every 25 cubic meters; and the temperature of the withering chamber is controlled between 4 DEG C and 12 DEG C. By the method, the withering time of the tea leaves can be shortened, the tea making efficiency is increased, moreover, the tea quality is also greatly improved, and the market competitiveness of the tea 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 low-temperature withering method with short withering time and keeping the freshness of tea leaves. [0006] A low-temperature withering method for dark green tea. The method adopts refrigeration t...
