Description

Technical Field

[0001] The utility model relates to the field of tea leaf moistening devices, and particularly relates to a cold air spray type green tea killing-off leaf moistening device. Background Technique

[0002] Green tea is one of the main tea categories in China. It refers to the new leaves or buds of tea trees, which are not fermented and are made into beverages through processes such as killing-off the green, shaping, and drying. The color of its finished products and the tea soup after brewing mostly preserve the green style of fresh tea leaves. In the green tea processing technology, after killing-off the green and before shaping, in order to facilitate shaping, it is necessary to carry out a moistening treatment on the tea leaves. Tea leaf moistening is a process that must be carried out after each firing process in the tea leaf processing process. In particular, the spreading and moistening after killing-off the green has the greatest impact on the tea leaf quality. Especially for high-aroma green tea varieties, there are slight differences in the killing-off the green technology from other famous teas. Usually, the moisture content of the killed-off green leaves is generally low, some are about 55%. If the moistening of the killed-off green leaves is not in place, the moisture redistribution between the leaves and the stems is uneven, the leaves do not become soft, and it is easy to cause leaf breakage during the rolling process and it is difficult to form strips.

[0003] After retrieval, an intermittent cold air spray type green tea killing-off leaf moistening device with the publication number of CN201921373396.9 is specifically disclosed, including a moistening box. The four corners of the bottom end of the moistening box are all connected with support bases, and a liquid outlet is arranged at the middle position of the bottom end of the moistening box. The four side walls of the moistening box are all connected with water tanks, and a liquid discharging device is arranged inside the water tanks. Spray heads are installed on the four inner walls of the moistening box, and a liquid discharging pipe is communicated between the spray heads and the bottom end of the water tank. The top end of the moistening box is connected with an installation box, and a driving motor is installed in the installation box by screws. The structure of the utility model is novel, and this device can effectively and evenly moisten the green tea killing-off leaves, improve the moistening efficiency, and is suitable for popularization.

[0004] However, the above device still has certain defects. For example, most of the existing killing-off leaf moistening devices have a slow moistening speed, and it takes a lot of time for moistening, resulting in low moistening efficiency; most of the killing-off leaves are stationary during moistening, and the moistening effect at the bottom may be very different from that at the top, which may affect the subsequent processing and the quality of the processed tea leaves; after the tea leaves are moistened, the tea leaves in the placement box are taken out, and then un-moistened tea leaves are added to be moistened again, but the efficiency is very slow in this way and it cannot be replaced quickly.

[0005] Therefore, it is very necessary to invent a cold air spray type green tea killing-off leaf moistening device to solve the above problems. Content of the Utility Model
