Description

Technical Field

[0001] This utility model relates to the field of biscuit production and processing technology, and in particular to a biscuit drying equipment. Background Technology

[0002] Biscuits are foods made primarily from cereal flour, with added sugar, oil, and other ingredients, through processes such as mixing the flour (or batter), shaping, and baking (or frying). They also include foods for which cream, egg whites, cocoa, chocolate, etc., are added before or after cooking (either on the surface or inside). During biscuit production, the biscuits need to be dried to remove surface moisture.

[0003] Existing biscuit drying equipment suffers from the following drawbacks: First, static drying leads to uneven heating. Traditional equipment often uses fixed trays, resulting in unidirectional hot air flow that causes one side of the biscuit to be heated for an extended period, while the other side receives insufficient contact. This easily leads to problems such as localized dampness and uneven crispness. Especially for thicker biscuits, manual turning is required, which is not only inefficient but also prone to causing damage. Second, the mesh plates are mostly rigidly connected with bolts, requiring individual bolt removal for replacement, which is time-consuming and poses a risk of burns due to the high temperatures involved. These defects directly result in a significant reduction in drying efficiency, making it difficult to match the production capacity with the demands of large-scale production. Utility Model Content

[0004] The purpose of this utility model is to provide a biscuit production drying equipment, which solves the problems of uneven heating caused by static drying and the use of bolts to connect the mesh plates, which requires disassembling each screw individually when replacing them, is time-consuming, and is prone to burns during high-temperature operation.

[0005] To achieve the above objectives, a biscuit production drying device is provided, including a drying box. A door is hinged to the outside of the drying box, and a fixed frame is fixedly connected to the right end of the inside of the drying box. A motor is fixedly connected to the right end of the outside of the drying box, and a gear two is fixedly connected to the output end of the motor. A rotating shaft two is rotatably connected inside the fixed frame, and a gear one is fixedly connected to the right end of the rotating shaft two through the drying box and outward.

[0006] The first gear and the second gear mesh with each other. A cylinder is fixedly connected to the left side of the drying box. The extended end of the cylinder passes through the drying box and is fixedly connected to a movable frame. A rotating shaft is rotatably connected inside the movable frame.

[0007] According to the biscuit production drying equipment, both the first rotating shaft and the second rotating shaft are provided with connecting shafts, and the inner end of the connecting shaft is fixedly connected to a drying mesh plate.

[0008] According to the biscuit production drying equipment, the connecting shaft is internally threaded with rotating shaft one and rotating shaft two, and positioning bolt two is provided. Limiting grooves are opened at both ends of the upper part of the drying mesh plate.

[0009] According to the biscuit production drying equipment, a drying cover plate is installed at the upper opening of the drying mesh plate, and limit blocks are fixedly connected to both ends of the drying cover plate.

[0010] According to the biscuit production and drying equipment, the limiting block and the limiting groove correspond to each other, and the internal threads of the limiting block and the limiting groove are connected by a positioning bolt.

[0011] According to the biscuit production drying equipment, a drying component is fixedly connected to the rear end of the drying box, and an air inlet pipe is provided through one end of the drying component.

[0012] According to the biscuit production drying equipment, a mounting frame is fixedly connected to the upper inner side of the drying box, and a plurality of drying pipes are fixedly connected inside the mounting frame, the drying pipes being connected to the air inlet pipe.

[0013] According to the biscuit production drying equipment, a heat dissipation vent is provided on the left side of the drying box, and a support is fixedly connected to the four ends of the bottom of the drying box. A discharge port is provided through the middle of the lower end of the drying box, and a baffle is installed at the bottom of the discharge port.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. This equipment uses a motor-driven gear set to rotate the rotating shaft, causing the drying rack to rotate as a whole, thus achieving dynamic drying of the biscuits. The drying rack adopts a mesh structure design, which, together with the upper and lower mesh covers, clamps and fixes the biscuits, ensuring that the biscuits are evenly exposed to hot air on both sides during rotation. Compared with static drying, the rotation mechanism effectively avoids the problems of uneven heating on one side and localized dampness and softness. At the same time, it accelerates the speed at which hot air penetrates the gaps between the biscuits. Combined with the multi-hole air outlets of the drying tube, the heat can cover the surface of the biscuits in all directions, greatly shortening the drying time, improving the consistency of the crispness of the finished product, and reducing the defect rate.

[0016] 2. The drying screen in this device adopts a double locking structure of cylinder-driven movable frame and positioning bolts, which realizes one-button disassembly. During operation, you only need to start the cylinder to retract the movable frame and loosen the positioning bolts to pull out the screen. No tools are required throughout the process, which improves the convenience of the entire drying equipment.
