The utility model relates to the technical field of biscuit processing, and one embodiment of the disclosure provides biscuit baking equipment with a heat recovery function, the biscuit baking equipment comprises a baking oven, a heating coil is arranged in the baking oven, a heat regeneration cover is inserted into the upper end face of the baking oven, an insertion pipe is arranged at the upper end of the heat regeneration cover, a communicating pipe is inserted into the insertion pipe, and the communicating pipe is communicated with the heating coil. An inserting cover is arranged at the tail end of the communicating pipe, a locking strip is arranged on the inner side wall of the inserting cover, a pushing spring is arranged on the inner side wall of the locking strip, and the pushing spring is arranged on the inner side wall of the inserting cover. By means of the technical scheme, the problems that in the prior art, a large amount of hot steam and hot air can be generated in the baking process, heat is usually directly discharged to the outside, energy waste is caused, the production cost is increased, the temperature of a baking workshop can rise, the working environment of the workshop is affected, and the working environment is affected are solved. And even extra cooling equipment is needed to maintain a proper temperature, so that the energy consumption is further increased.

The application discloses a box cover opening and closing type tea baking machine, which comprises a box body, a baking screen and a heating pipe arranged in the box body, a base plate arranged on the inner wall of the box body, vertical slots and circular arc track slots arranged on the base plate, L-shaped positioning lock hooks, connecting rods, and cranks. The top of the L-shaped positioning lock hook is connected with the bottom surface of the box cover, the middle part of the L-shaped positioning lock hook is rotatably provided with a first rotating shaft pivot, the bottom of the L-shaped positioning lock hook is provided with a second rotating shaft pivot, the top end of the connecting rod is rotatably connected with the second rotating shaft pivot, the bottom end of the connecting rod is rotatably connected with a third rotating shaft pivot, and the bottom end of the crank is rotatably connected with a fourth rotating shaft pivot. The torque of the driving motor is transmitted to the box cover through the linkage structure composed of the L-shaped positioning lock hook, the connecting rod, the crank and the rotating shaft pivot, and the linkage structure is used for forming the floating connection and the flexible transmission through the movement gap and the tolerance between the multiple components, so that the stability and consistency of the opening and closing action of the box cover are improved.

This invention provides an oven with good airflow uniformity, comprising: an outer casing, an inner casing installed inside the outer casing, a back sealing plate for the air cavity installed on the back of the inner casing, a front air cavity plate installed in front of the back sealing plate inside the inner casing, a circulating air distribution hole opened in the center of the front air cavity plate, and side air distribution plates installed on the left and right sides of the front air cavity plate inside the inner casing, with air distribution holes evenly distributed on the surface of the side air distribution plates. The gaps between the side air distribution plates, the inner casing, the back sealing plate, and the front air cavity plate form a circulating air cavity. A circulating fan assembly and a ring-shaped heating element are both installed inside the circulating air cavity, with the ring-shaped heating element installed on the outside of the circulating fan assembly. Through the structural design of the circulating air cavity and the side air distribution plates, this invention enables the circulating hot air inside the oven to have good airflow uniformity, thereby improving the baking quality of the oven.
