Problems solved by technology

However, before finishing, it needs to be pre-treated so that it can meet the finishing treatment and can not cause damage to fresh leaves. At present, manual processing or manual auxiliary equipment is used for processing. First, the tea cannot be treated evenly, and second, the processing efficiency extremely low

Embodiment Construction

[0008] The method of the present invention includes three steps of spreading, heating and dehumidification. First, the fresh leaves are evenly spread by using a spreading machine. The thickness of the fresh leaves is not more than 1cm. The heating zone is a closed space. The heating zone heats the temperature to 55°C through the heater, and at the same time dehumidifies through the dehumidifier in the heating zone. After continuous heating for 2 hours, stop heating and continue dehumidification for 1.5 hours. After the end, when the temperature drops to room temperature, the fresh leaves are transported out of the heating area, placed under natural conditions for 30 minutes, and then the greening treatment can be carried out. The fresh leaves treated by the method of the invention are de-enzymed, the water content is moderate, the fresh leaves are basically not damaged, the processing efficiency is high, and the processed tea leaves are beautiful and taste good.

Abstract

The present invention discloses a Liu'an Guapian tea treatment method before enzyme deactivating. The treatment method includes three steps of spreading, heating and dehumidifying. Firstly, a spreading machine is used to evenly spread fresh tea leaves, the spread tea leaves are transported into a heating zone via a conveyor belt, a heating machine is used to heat the fresh tea leaves to 55 DEG C in the heating zone, at the same time, a dehumidifier in the heating zone is used to conduct dehumidification, after heating is continuously conducted for 2 hours, the heating is stopped, the dehumidification is continuously conducted for 1.5 hours, after the dehumidification is completed, the temperature is lowered to room temperature, the fresh tea leaves are transferred out from the heating zone and the transferred tea leaves are allowed to stand in a natural condition for 30 minutes, and then the fresh tea leaves are subjected to the enzyme deactivating treatment. The treated fresh tea leaves by the method are subjected to the enzyme deactivating treatment and moderate in water content. The treatment method is basically free of harm to the fresh tea leaves and high in processing efficiency. The processed tea leaves are beautiful in appearance and good in tastes.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a pretreatment method for Lu'an melon slices before greening. Background technique [0002] Lu'an Guapian is a special type of green tea. "It has a long history and rich cultural connotations. Among all the teas in the world, Lu'an Guapian is the only tea with no buds and no stems. It is made from a single piece of raw leaves. After removing the buds, it not only maintains a single piece of shape, but also has no grassy taste. , the stalk has been lignified during the production process. After removal, it can ensure that the tea taste is strong but not bitter, fragrant but not astringent. However, before killing green, it needs to be pre-treated so that it can meet the killing treatment and can not cause damage to fresh leaves. Damage is currently mostly handled manually or with artificial auxiliary equipment. First, the tea cannot be treated evenly, and second, the proce...
