Description

Technical Field

[0001] The invention relates to the technical field of powder processing, in particular to a soluble starch centrifugal processing device. Background Art

[0002] Soluble starch is a type of starch that can dissolve in water. It is mainly composed of amylose and amylopectin. It is usually extracted from plants such as corn, potato, wheat and cassava, and is widely used in food, medicine and industry. When starch is in the form of starch slurry during the production and processing, it is necessary to use centrifugal equipment to remove the moisture in the starch slurry. During the centrifugation process, the solid starch particles are separated and deposited on the outer wall of the centrifuge, while the liquid part (usually a slurry containing water and other impurities) is discharged. Centrifugal processing can achieve efficient water removal in a short time and shorten the production cycle.

[0003] Existing soluble starch centrifugal drying equipment generally does not have the function of purifying starch slurry, resulting in more solid particle impurities in the starch particles after drying, and it is more difficult to separate solid particle impurities from the starch powder particles after drying. In addition, the existing centrifugal drying chamber is usually a single large chamber, and the hot air has a limited coverage range, which cannot effectively and evenly heat and dry the atomized slurry. The obtained starch powder is generally relatively moist and needs to be subsequently dried and heated, which affects the output efficiency of starch. Therefore, the present invention proposes a soluble starch centrifugal processing equipment to solve the problems mentioned in the above background technology. Summary of the invention

[0033] Furthermore, referring to Figure 2 , 3, 5, 8, a driving motor connected to a conical disk 9 is installed inside the impurity removal chamber 1, and a plurality of slots 18 corresponding to the blades of the centrifugal wheel disk 7 are provided on the surface of the conical disk 9. After the frame 5 structure is installed, a plurality of blades on the lower side of the centrifugal wheel disk 7 inside it are inserted into the slots 18 on the surface of the conical disk 9, so that the frame filter 5 in the frame 5 is connected with the conical disk 9. A through hole is provided in the center of the centrifugal wheel disk 7, and a plurality of blades are fixed on the upper and lower sides of the centrifugal wheel disk 7, and the plurality of blades are arranged in a circle. When the driving motor is in a working state, the driving motor drives the connected conical disk 9 and the centrifugal wheel disk 7 thereon to rotate, and the starch slurry is centrifuged.

[0035] Furthermore, referring to Figure 3The other end of the circulation pipe 20 is located on the upper side of the storage barrel 3. A filter frame 14 corresponding to the outlet of the other end of the circulation pipe 20 is installed on the upper side of the storage barrel 3. A filter screen is arranged on the lower side of the filter frame 14. Before the starch slurry in the circulation pipe 20 flows back to the storage barrel 3 through the other end, the starch slurry can be repeatedly removed by the filter screen on the lower side of the filter frame 14, thereby improving the purity of the starch particles obtained by drying.

[0036] Furthermore, referring to Figure 5 , 8 A cleaning ring 12 is rotatably connected to the inner side of the frame filter 6 on the periphery of the conical disk 9, a scraper sheet 16 corresponding to the inner side of the frame filter 6 is fixed to the upper part of one side of the cleaning ring 12, a chip discharge port 15 is provided on one side of the impurity removal chamber 1, a blocking block 17 is fixed to the upper part of the other side of the cleaning ring 12, and the blocking block 17 is located on the upper side of the chip discharge port 15, a ratchet block 19 is rotatably connected to the edge of the conical disk 9, and notches are provided on the inner side of the peripheral cleaning ring 12 and the corresponding positions of the edge of the conical disk 9, and a torsion spring is provided at the junction of the ratchet block 19. When the above-mentioned driving motor drives the upper conical disk 9 to rotate, it rotates counterclockwise, and its outer ratchet block 19 rotates counterclockwise. The block 19 does not conflict with the gap of the outer cleaning ring 12. When the equipment stops working and is maintained and repaired, the frame filter 6 needs to be cleaned. At this time, when the conical disk 9 connected to the drive motor is controlled to rotate clockwise, the conical disk 9 rotates through the ratchet block 19 to conflict with the outer cleaning ring 12. The cleaning ring 12 rotates and cleans the inner wall of the frame filter 6 through the scraper piece 16 thereon. At the same time, the blocking block 17 on the scraper piece 16 moves out of the upper side of the chip discharge port 15, the upper side opening of the chip discharge port 15 is opened, and the granular waste scraped by the scraper piece 16 is swept into the chip discharge port 15 for discharge.
