Description

Technical Field

[0001] The utility model belongs to the technical field of tea fermentation pretreatment, in particular to a raw material pretreatment device for cooked tea fermentation. Background Art

[0002] Ripe tea fermentation is a special tea processing process, mainly involving Pu'er tea and dark tea. The purpose is to transform the substances in the tea leaves through the action of microorganisms and enzymes, so as to improve the quality of the tea leaves. The pretreatment of raw materials for ripe tea fermentation is a general term for all processing processes of the picked tea raw materials before fermentation, such as cleaning, withering and dehydration, screening, drying, etc.

[0003] Existing raw material pretreatment devices, such as a Pu'er tea fermentation raw material pretreatment device disclosed in application number CN202320642916.1, can measure the amount of Pu'er tea through a baffle, thereby achieving the beneficial effect of better pile fermentation of Pu'er tea, and clean the Pu'er tea fermentation raw materials through a water tank, and stir the Pu'er tea fermentation raw materials through a stirring rod, so that the water tank flushes the Pu'er tea fermentation raw materials, and the separation net facilitates the separation of the size of the Pu'er tea fermentation raw materials.

[0004] However, in the process of cleaning tea leaves, the tea leaves in contact with the stirring roller are easily broken, resulting in more debris, which affects the appearance and quality of the tea leaves and causes unnecessary waste. In addition, due to the irregular shape of the tea leaves and the curling on the surface, the traditional cleaning method is less effective. Especially after cleaning, it is difficult to effectively remove the water on the surface of the tea leaves by relying solely on the automatic screening of the screen, which results in excessive moisture in the piled tea leaves, affecting the taste. To this end, we propose a raw material pretreatment device for ripe tea fermentation to solve the above problems. Utility Model Content
