Description

Technical Field

[0001] This utility model relates to the technical field of potato processing equipment, specifically a rotary peeling device for washing and peeling potatoes. Background Technology

[0002] After harvesting, potato flour processing enterprises need to peel large quantities of potatoes for subsequent flour production. Currently, enterprises generally use mechanical friction peeling equipment for batch processing. However, existing equipment still has significant shortcomings in practical application: 1. Low peeling efficiency and high damage rate: Traditional flat grinding discs or rollers have a simple inner wall structure, which restricts the movement trajectory of potatoes during the peeling process and causes uneven friction. This results in incomplete peeling or excessive local friction, which damages the potato flesh and affects the yield and product quality.

[0003] 2. Inadequate cleaning and drainage system: Most existing equipment lacks effective water circulation and drainage design. The rinsing water fails to cover the entire working area, and residue easily accumulates at the bottom of the equipment. This not only affects the peeling effect but may also cause equipment blockage or incomplete cleaning, increasing maintenance costs. Utility Model Content

[0024] This embodiment provides a rotary potato peeling device, the core design of which lies in achieving efficient peeling through the synergistic friction between the grinding disc 10 and the inner wall of the cylinder, combined with water rinsing. Figure 1-6 As shown, the main body of the device consists of a base 1, a base 2, a cylinder, and a peeling assembly. The base 1 is vertically arranged and fixed to the base 2 with bolts. The base 2 is rigidly connected to the ground with anchor bolts to ensure the stability of the equipment operation. The cylinder adopts a split design, including a cylinder body 3, a cylinder bottom 4, and a cylinder cover 5. The cylinder body 3 is a hollow straight cylinder structure with openings at the top and bottom. The cylinder bottom 4 is connected to the cylinder body 3 through flanges, and a sealing gasket is added between the flanges to prevent water leakage. The cylinder cover 5 is fastened to the top of the cylinder body 3 and fixed with bolts for easy and quick disassembly to achieve batch feeding of potatoes.

[0025] The core of the peeling assembly is the rotating system of the grinding disc 10 driven by the motor 6. The motor 6 is fixed to one side of the base 1, and its output shaft is connected to the driving gear 7 via a key. The driving gear 7 meshes with the driven gear 8 (the module ratio is designed to be 1:3 to achieve speed reduction transmission). The driven gear 8 is connected to the shaft 9 via a key. The shaft 9 vertically passes through the bearing seat in the center of the bottom of the cylinder 4, and the top is fixed to the horizontal grinding disc 10 by bolts. The gear set is arranged in the sealed cavity between the bottom of the cylinder 4 and the base 1 to avoid external impurities from interfering with the transmission. After the motor 6 starts, it drives the shaft 9 to drive the grinding disc 10 to rotate horizontally in the circumferential direction through gear reduction. The speed is controlled at 80-120 rpm to balance the peeling efficiency and the potato damage rate.

[0026] The grinding disc 10 consists of three parts: a base plate 14, grinding plates 15, and bushings 16. The base plate 14 is made of circular carbon steel plate, and the surface is sandblasted and then bonded with diamond abrasive to enhance the basic friction. The bushing 16 is vertically welded to the center of the base plate 14. The inner hole and the shaft 9 are fitted with a transition fit and are circumferentially fixed by a flat key. Bolts are also used to prevent the bushing from detaching and to ensure the stability of power transmission. There are six grinding plates 15, which are evenly distributed radially around the bushings 16. Adjacent grinding plates 15 are tightly connected by welding to form a three-dimensional hexagonal star surface. Each grinding plate 15 is composed of symmetrically arranged isosceles triangular plates. The grinding plates 15 are welded to the surface of the base plate 14 with their short sides welded together. The other short side of the adjacent grinding plates 15 is fixed by spot welding to form a ring structure with the ends connected. The long side is connected to the adjacent grinding plate 16. The long sides of the 5 plates are inclined and interlocked, with an included angle of 140° between them, forming a three-dimensional surface with a height difference between the concave and convex parts. After the 6 grinding plates 15 are combined, the whole structure presents a three-dimensional hexagonal outline, which causes the potatoes to generate multi-directional throwing motion during the rolling process. The three-dimensional structure concentrates the contact pressure in the raised area, which greatly improves the peeling efficiency compared to the flat grinding disc 10 and effectively breaks the potato epidermal cells. The concave area forms a turbulent zone, which accelerates the removal of residue. During the rotation of the grinding disc 10, the potato is subjected to the combined action of centrifugal force and structural resistance, and its movement trajectory presents a "rotation-throwing-impact" cycle, which greatly shortens the single cycle and effectively improves the peeling efficiency. The composite design of the diamond-shaped rod 11 on the inner wall of the cylinder 3 and the three-dimensional structure of the grinding plate 15 ensures that the potato is simultaneously subjected to longitudinal friction of the grinding disc 10 and transverse scraping of the rod 11.

[0027] The top of the cylinder cover 5 is equipped with a spray head for an external water pump. The spray head is arranged in a ring shape, and the spray angle covers the entire cross-section of the cylinder. The water pump pressure is set to 0.3MPa, and the water mist particle size is controlled at 50-100μm to achieve the dual effect of dust reduction and residue softening. An annular flow channel is opened at the bottom of the cylinder body 3. The bottom surface of the flow channel is inclined at 45° and points to the drain port 12. The rinsing water is collected along the flow channel and discharged from the drain port 12 to avoid water accumulation and submersion of the grinding disc 10. The flow channel capacity is designed to be 1.5 times the water volume of a single cleaning to ensure drainage efficiency. A discharge baffle 13 is set at the upper part of the cylinder body 3 near the grinding disc 10. The baffle is connected to the cylinder body 3 by a hinge. When closed, it achieves IP55 protection level through a silicone sealing ring (hardness 50 Shore A) to prevent rinsing water from splashing out. A pusher can also be added below the bottom plate 14 at a position that matches the flow channel to push the potato residue accumulated in the flow channel to the drain port 12.

[0028] The workflow is as follows: When feeding, open the cylinder cover 5, pour the potatoes into the cylinder, close the cylinder cover 5 and tighten the bolts, then start the motor 6. The grinding disc 10 rotates and drives the potatoes to tumble. The rods 11 on the inner wall of the cylinder 3 work together with the grinding disc 10 to rub the skin. The process continues for 3-5 minutes. At the same time, the water pump is turned on and the spray nozzle sprays water mist to wash away the residue. The wastewater is discharged through the annular flow channel. The discharge baffle 13 is opened and the grinding disc 10 continues to rotate for 1 minute. Centrifugal force is used to discharge the peeled potatoes from the baffle opening.

[0029] The above embodiments detail the structure, working principle, and technical advantages of the rotary potato peeling device. Through the coordinated friction between the grinding disc 10 and the inner wall of the cylinder, and the integrated design of the water flushing and sewage discharge system, a high-efficiency and low-damage peeling effect is achieved.
