[0040] Working principle of the utility model:
[0041] 1. Tea spreading stage:
[0042] White tea is placed on the filter layer of the drying tray, and is stacked at the front end of the upright frame as much as possible to facilitate uniform spreading when the upright frame is pushed, and the moisture on the white tea is infiltrated to the water absorption layer through the filter grid plate to avoid tea soaking.
[0043] 2. The scraping uniformization stage: adjust the height of the double-end screw on the vertical frame according to the thickness of the white tea to be laid, then lock the position through the bolt, then put the scraping plate into the smooth section of the double-end screw and adjust the inclination angle of the scraping plate, it is to be noted that the sleeve ring has a certain hardness, which facilitates opening and closing installation and replacement, after the scraping plate is put into the double-end screw, the lowest point position of the scraping plate is adjusted by rotating the sleeve ring, which facilitates material laying, at this time the distance between the lowest point of the scraping plate and the drying tray is the thickness of the tea to be dried, then start the motor, drive the guide wheel to move along the guide rail table through the motor, drive the two vertical frames to slide synchronously through the linkage rod, and stop walking when the vertical frame reaches the limit position and is sensed by the photoelectric sensor, and wait for the instruction to move reversely;
[0044] The scraping plate reciprocates horizontally under the traction of the double-end screw, and the V-shaped structure with an included angle greater than 90° spreads the tea leaves to both sides, realizing automatic and uniform material laying and facilitating tea leaf drying;
[0045] In order to avoid too much white tea, a material collecting table is arranged on the inner side of the support for receiving excess white tea, so as to avoid pollution caused by tea falling during automatic material laying, after the material laying is completed, the excess tea will fall into the material collecting table, the excess tea is collected again and placed into the next drying process or put into another drying device for flat drying, it is to be noted that after the excess tea is collected, the collecting table needs to be wiped to remove the moisture.
[0046] 3. The material collecting and cleaning stage:
[0047] After drying, adjust the angle of the scraping plate on the sleeve ring so that the scraping plate can move along the plane of the drying tray, and then push most of the dried tea leaves to the material collecting table, the inclined baffle guides the tea leaves to fall into the material collecting table, then the white tea can be collected manually, the remaining small part of tea leaves that cannot be scraped may need to be manually removed; during this process, the water absorption paper can be replaced according to the water content of the water absorption paper.
