Description

Technical Field

[0001] The utility model relates to tea fermentation equipment, in particular to a closed continuous tea heat pump fermentation machine. Background Art

[0002] Fermentation is one of the necessary steps in making black tea. The purpose of fermentation is to oxidize the polyphenols in the tea leaves under the promotion of enzymes, causing the green tea leaves to turn red. It is a key process in forming the color, aroma and taste quality characteristics of black tea, and is mainly affected by fermentation time, temperature, humidity and oxygen concentration.

[0003] At present, the fermentation process equipment on the continuous processing production line of black tea with large batch output mainly adopts the method of open fermentation and external temperature control and humidification. The tea to be fermented is transported to the fermentation machine by a conveyor, and the fermentation machine is placed in the fermentation room. The fermentation room is equipped with air-conditioning equipment and humidification equipment. During fermentation, the temperature and humidity are manually controlled to achieve the environment required for tea fermentation. The fermentation room occupies a large area, has low control accuracy, poor fermentation uniformity, and the fermentation process parameters cannot be integrated into the production line system, and the degree of intelligence is low. The closed fermentation equipment is generally used for single-machine fermentation with small batch output. Anaerobic phenomena are prone to occur during the fermentation process. When the ambient temperature is higher than the required fermentation temperature, the fermentation cannot be carried out, the fermentation effect is poor, and the quality is difficult to control.
