Description

Technical Field

[0001] This utility model belongs to the field of frozen dehulling technology for fresh rice, and specifically relates to a frozen dehulling device for fresh rice. Background Technology

[0002] The fresh rice freezing dehulling device utilizes freezing to create a temperature difference and physical changes between the rice husk and brown rice, making the husk brittle and weakening its bond with the brown rice. Then, through specific dehulling equipment and mechanical actions, such as grinding, squeezing, and friction, the husk is more easily separated from the brown rice, thus achieving dehulling. This reduces damage to the brown rice and better preserves the rice's nutrients and freshness.

[0003] For example, patent CN214716860U discloses a frozen dehulling device for fresh rice, including a dehulling unit and a freezing unit. A conveying unit for transporting grains connects the freezing unit and the dehulling unit. The dehulling unit includes an inner cylinder and an outer cylinder that rotate in opposite directions. The outer cylinder is open at both ends and concentrically fitted around the inner cylinder. A spiral baffle is provided between the outer cylinder and the inner cylinder, spirally arranged from top to bottom and fixedly connected to the inner wall of the outer cylinder. The freezing unit includes a freezing cylinder and cooling plates. The conveying unit includes a lifting cylinder and a lifting auger. An adjusting component for controlling the feeding speed is installed at the top of the lifting cylinder. The adjusting component includes an adjusting sleeve, a first connecting rod, a mounting rod, and an elastic support net. With an inner cylinder, an outer cylinder, and spiral baffles, it can dehull a large quantity of grains, improving work efficiency, slowing down the grain movement speed, ensuring the grains are fully dehulled, and improving the quality of fresh rice.

[0004] During the use of the aforementioned fresh rice freezing and dehulling device, the frozen rice is discharged from the outlet of the lifting cylinder and discharged into the inner and outer cylinders for dehulling as the auger moves. Inevitably, a lot of dust will float up. If this dust is not treated, it will have a certain impact on the surrounding environment and people. Utility Model Content
