Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grinders, in particular to a grinder for freeze-dried durian shells. Background Art
[0002] Durian freeze-dried shell refers to the durian shell that has been freeze-dried. Freeze-drying technology is a process in which food or other substances are frozen at low temperatures and an appropriate vacuum is applied to remove moisture from the solid state into a gaseous state. By processing in this way, the durian shell can be preserved for a longer time while retaining its natural nutrients and flavor. The durian freeze-dried shell grinder is a mechanical equipment specially used to grind the durian freeze-dried shell into powder.
[0003] Existing grinders for freeze-dried durian shells usually do not perform drying after grinding, or the drying is not sufficient. During the grinding process, the freeze-dried durian shells will release moisture, resulting in a higher moisture content in the final product, which may affect the storage stability of the product, increase the risk of mold or microbial contamination, and reduce the quality of the product. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the existing grinders for freezing-dried durian shells usually do not perform drying treatment after grinding, or the drying is not sufficient, which affects the storage stability of the product and reduces the quality of the product.
[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: a grinder for freeze-dried durian shells, comprising a box body, a material receiving basket is slidably connected in the box body, a fixed cylinder is fixedly connected to the bottom of the material receiving basket, a chamber is arranged in the fixed cylinder, a sliding shaft is arranged in the chamber, the sliding shaft slides through the fixed cylinder, a first return spring is arranged in the chamber, and both ends of the first return spring are fixedly connected to the fixed cylinder and the sliding shaft respectively.
[0006] The utility model is further configured that one end of the sliding shaft away from the fixed cylinder is rotatably connected to a T-shaped connecting shaft, both ends of the T-shaped connecting shaft are respectively fixedly connected to cams, and one side of the inner wall of the box body is fixedly connected to a first motor.
[0007] The utility model is further configured such that the output end of the first motor is fixedly connected to a first rotating shaft, the first rotating shaft is fixedly connected to one of the cams, and the other cam is fixedly connected to a second rotating shaft at one end away from the T-shaped connecting shaft.
[0008] The utility model is further configured that a bearing is provided at one end of the second rotating shaft away from the cam, and the bearing is fixedly connected to the box body.
[0009] Through the above technical solution, the setting of the bearing reduces the friction resistance of the second rotating shaft, allowing it to rotate more smoothly, which improves the operating efficiency of the machine, reduces energy consumption, and helps to reduce energy waste in the production process.
[0010] The utility model is further configured that sliding grooves are respectively opened on both sides of the inner wall of the box, and sliders are slidably connected in the two sliding grooves. The bottom ends of the two sliders are fixedly connected to second return springs, the other ends of the second return springs are fixedly connected to the box, and two heating plates are fixedly connected to the bottom end of the material receiving basket.
[0011] Through the above technical solution, during the grinding process, the product may absorb moisture or generate trace amounts of water. Heating and drying can effectively remove this excess moisture and ensure that the final product is properly dry, which helps to increase the shelf life of the product and reduce the risk of mold or bacterial growth.
[0012] The utility model is further configured as follows: a freezing chamber is arranged in the box body, a temperature insulation board is fixedly connected to the box body, a through hole is opened on the temperature insulation board, and two baffles are arranged below the through hole.
[0013] The utility model is further configured that cylinders are fixedly connected to both sides of the inner wall of the box, two output ends of the cylinders are fixedly connected to two baffles, and a grinding box is fixedly connected to the box.
[0014] The utility model is further configured that a first grinding roller and a second grinding roller are rotatably connected in the grinding box, a second motor is fixedly connected in the box, a second gear is fixedly connected to the output end of the second motor, and a blanking hole is opened at the bottom of the grinding box.
[0015] The utility model is further configured that a first gear is rotatably connected to one side of the grinding box, the first gear is fixedly connected to the second grinding roller, the second gear is meshed with the first gear, and the second gear is fixedly connected to the first grinding roller.
[0016] The utility model is further configured that a protective door is rotatably connected to one side of the box body, a handle is fixedly connected to the protective door, and two observation windows are arranged on the protective door.
[0017] Through the above technical solution, the observation window enables the operator to maintain a safe distance during the processing and does not have to open the machine casing to observe the processing situation, which helps to reduce the risk of accidental injury while ensuring the safety of the operator.
[0018] The beneficial effects of the utility model are as follows:
[0019] The utility model drives the sliding shaft to slide up and down in the fixed cylinder when the cam rotates, and impacts the fixed cylinder to a certain extent, so that the receiving basket can vibrate, and the vibration of the receiving basket can help the durian freeze-dried shell particles to remain in a loose state during the drying process, and prevent the durian freeze-dried shell particles from agglomerating or gathering together during the drying process, which helps to ensure that the particles are dried evenly, avoids local insufficient drying or excessive drying caused by too tight contact between particles, promotes air ventilation and heat transfer, helps to accelerate the drying speed, and improves the drying efficiency and product quality.
