Description

Technical Field

[0001] The utility model relates to the technical field of tea processing equipment, in particular to a baking machine for green tea production. Background Art

[0002] A tea baking and fragrance enhancing machine is a processing equipment used to improve the quality and taste of tea; through high-temperature baking, the moisture in the tea is quickly evaporated, thereby reducing the moisture content of the tea and improving the aroma, taste and color of the tea. The tea baking and fragrance enhancing machine is widely used in the processing of various teas such as green tea, black tea, oolong tea, and pu-erh tea;

[0003] In the prior art, the more reset process is to layer by layer place the drawer trays filled with tea into the structure inside the baking machine, and then control the rotation of the drawer trays inside the equipment. This installation structure needs to ensure the rotation stability of the drawer trays while also designing enough space for the loading and unloading of the drawer trays. To achieve these two effects, the traditional structure will have the problem of complex use, and the process of opening and loading the inclined drawer trays is relatively difficult. For the above problems, the document with the application number 202410443137.8 discloses a tea baking and fragrance enhancing machine, which includes a baking machine and a drawer tray. An arrangement structure for stacking a plurality of drawer trays is rotationally assembled inside the baking machine. The arrangement structure is rotationally assembled by a plurality of groups of fixed rods and pipe rods. On both sides of the surface of the bottom turntable, outward extending arc guide grooves 1 are symmetrically arranged at points. On both sides of the lower surface of the top turntable, outward extending arc guide grooves 2 are symmetrically arranged at points. Inner retractable rods are movably inserted into both ends of the pipe rod. A through rod is movably installed inside the second vertical rod. When both ends of the second vertical rod move to the outermost ends of the outward extending arc guide groove 1 and the outward extending arc guide groove 2 respectively, the inner retractable rod extends out of the pipe rod and the pressing plate moves up at the same time;

[0004] However, after reading the above patent document, the following deficiencies are found: When in use, since the drying hot air passes above the tray to dry the tea, the tea spread on the surface of the tray receives more heat and has a better drying effect. However, the drying effect of the tea inside is poor. Therefore, it is necessary to extend the drying time during drying, which not only affects the processing efficiency but also easily causes different drying degrees of the inner and outer tea, affecting the quality of the tea, and there is room for improvement.
