[0002] Black tea fermentation is a key process for the formation of black tea color, aroma and flavor. It is a series of chemical changes based on the oxidation polymerization of polyphenol compounds. The key point is to control the temperature, humidity and oxygen required for the reaction between enzyme and substrate, that is, to ensure that the fresh tea leaves are in an appropriate temperature and humidity environment and fully in contact with the air. At present, the better solution is to place the rolled leaves in a fermentation box and achieve the goal by controlling the temperature and humidity of the fermentation box.
[0003] However, the steam inlet in the existing fermentation box is generally located at the top or bottom of the box, and most of them are fixed in one position, which will cause uneven distribution of humidity and temperature inside the box. In addition, the tea leaves in the existing fermentation box are generally in a static state, which is not convenient for turning the tea leaves over for fermentation. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the existing fermentation box easily causes uneven distribution of temperature and humidity in the box due to the arrangement of the steam transmission port, and is inconvenient for turning the tea leaves and fermenting them uniformly.
[0005] To solve the above problems, the technical solution adopted by the utility model is a continuous black tea fermentation machine, including a cabinet body, a partition is fixed on the inside of the cabinet body, and several pairs of limit slide rails are fixed between the two sides of the partition and the two sides of the cabinet body, a fermentation plate is slidably arranged above each pair of limit slide rails, a groove is opened on the upper side of the fermentation plate, and several flip plates are rotatably arranged in the groove, a connecting rod is fixed at one end of the flip plate through the groove, a convex rod is fixed on the side of one end of the connecting rod, a support seat is fixed on one side of the fermentation plate, a telescopic rod is fixed above the support seat, a long rod is fixed at one end of the telescopic rod, and several right-angle hitting rods are fixed on the upper side of the long rod, a steam transmission channel is opened inside the partition between every two limit slide rails, one end of the steam transmission channel is connected with a main channel, and steam transmission holes are opened on both sides of the steam transmission channel.
[0006] As a further solution of the utility model: the right-angle end of the right-angle hitting rod is fixed downward on the upper side of the long rod, and the protruding rod is located in the middle of the right-angle hitting rod, so that the right-angle hitting rod can easily contact the protruding rod to drive it to rotate.
[0007] As a further solution of the utility model: the highest position of the right-angle hitting rod is higher than the highest position of the connecting rod after being vertically erected, which can effectively prevent the connecting rod from escaping from the limit of the right-angle hitting rod.
[0008] As a further solution of the utility model: a steam delivery port is provided at the top of the cabinet at the top of the main channel, and the steam delivery port is connected to an external steam delivery device for delivering steam to facilitate fermentation.
[0009] As a further solution of the utility model: the turning angle of the turning plate is ninety degrees, so as to pile the tea leaves.
[0010] As a further solution of the utility model: an opening is provided on one side of the cabinet, and sealing doors are hingedly connected to both sides of the cabinet at the opening to seal the cabinet.
[0011] As a further solution of the utility model: the telescopic rod is electrically connected to an external power source.
[0012] Compared with the prior art, the utility model has the following advantages: 1. The utility model adds a partition structure and a uniformly distributed air transmission channel, which can make the tea leaves on each layer fermented and make the temperature and humidity inside the cabinet evenly distributed;
[0013] 2. A turning plate is added to lay the tea leaves directly on the turning plate. After fermenting for a period of time, the turning plate is turned 90 degrees to pile the tea leaves into strips, which is convenient for fermenting the tea leaves originally at the bottom and makes the tea leaves ferment more evenly.
