Self-stirring deblocking type tea fermentation tank
Technical Field
The invention relates to the technical field of tea making equipment, in particular to the technical field of tea fermentation tanks.
Background
The fermentation is a tea-making step of changing tea components by enzymatic oxidation or microbial action to adjust flavor, color, shelf life and functional components, and according to the degree of fermentation, tea can be classified into unfermented teas (i.e., green tea such as Longjing tea, biluochun tea, mao Feng tea, etc.), slightly fermented teas (i.e., yellow tea such as Junshan silver needle, huoshan yellow bud, etc.), slightly fermented teas (i.e., white tea such as pekou silver needle, huoshan tea, etc.), partially fermented teas (i.e., oolong tea such as Tieguanyin, dahongpao tea, fenghuang Dancong tea, etc.), fully fermented teas (i.e., black tea such as Zhengshan tea, qimen black tea, etc.), and post-fermented teas (i.e.g., black tea such as Pu' er tea, anhua black tea, etc.).
In order to ensure uniform tea fermentation effect, the tea needs to be turned and stirred during fermentation, in the traditional tea making process, the operation process is usually completed by manually holding tools such as a rake, a shovel and the like by workers, and the problems of high labor intensity, poor labor condition and low production efficiency are solved, and the sanitation problem is easy to occur.
Based on the above, some manufacturers choose to directly rotate the tea fermenter with the tea leaf at regular intervals, such as a black tea fermentation device with the publication number of CN103283880B, so that the tea leaves are subjected to position change and mixing (i.e. eversion) during the rotation of the fermenter, however, the control of the stirring uniformity of the tea leaves is often limited, especially in the case of large volume of the fermenter and large amount of the tea leaves, in addition, when the caking phenomenon of the tea leaves occurs due to factors such as humidity and fermentation time, the rotating fermenter cannot effectively break up the caked tea leaves, so as to influence the fermentation effect, and some tea fermenters choose to singly stir the tea leaves (i.e. eversion) by a mode of built-in stirring pulp, such as a black tea fermentation device with a tea stirring mechanism with the publication number of CN116806901B, so that the stirring mode can more pertinently stir the tea leaves, so that the fermentation uniformity of the tea leaves is improved to a certain extent, however, in practical application, the single motion track of the stirring pulp can still break up the caked tea leaves, so that the caking quality of the caked tea leaves cannot be guaranteed.
