The utility model discloses a tea leaf fermentation device convenient for temperature control, which comprises a box body, a first sliding chute is arranged in the box body, the inner surface of the first sliding chute is connected with a sliding rod in a sliding manner, the lower surface of the sliding rod is fixedly connected with a sliding block, the lower surface of the sliding block is fixedly connected with a spring, and the spring is arranged in the first sliding chute. A second sliding groove is formed in the box body, a first pushing block is fixedly connected to the upper surface of a sliding rail, a threaded rod is rotatably connected to the interior of the box body, a connecting rod is in threaded connection to the outer surface of the threaded rod, and through cooperation of the first pushing block, the second pushing block, the connecting rod, a motor, the threaded rod, a sliding rod and a spring, the first pushing block and the second pushing block are matched; when the tea leaves are fermented, the filter screen is driven to slightly shake to increase gaps among the tea leaves, so that the tea leaves on the filter screen are driven to shake, the tea leaves can be fully fermented, the problems of insufficient fermentation of part of the tea leaves and excessive fermentation of part of the tea leaves are avoided, and finished fermented tea leaves are guaranteed.

This utility model belongs to the field of food fermentation technology, specifically a broken rice fermentation processing device, including a fermentation tank, and further including: a motor, fixed to the bottom of the fermentation tank; a turning component, disposed inside the fermentation tank and connected to the output end of the motor; a gas conveying component, disposed on the outside of the second fixed frame, with the gas conveying end disposed on the inside of the turning component; and a cover plate assembly, disposed on the inside of the top of the fermentation tank. This utility model provides a broken rice fermentation processing device that, through a motor-driven turning component, periodically turns the broken rice raw material inside the fermentation tank during the fermentation process, ensuring the uniformity of the fermentation process, avoiding incomplete or excessive fermentation in certain areas, and helping to release the gas generated during fermentation, maintaining gas circulation, preventing gas accumulation, avoiding oxygen deficiency or overheating, and ensuring a suitable fermentation environment.
