Description

Technical Field

[0001] This utility model relates to the field of food processing, specifically to a sweet potato chopping device for preparing sweet potato starch. Background Technology

[0002] Sweet potato starch, as an important plant starch resource, boasts unique physicochemical properties and rich nutritional value, demonstrating wide application value in various fields such as food, industry, and medicine. The production process of sweet potato starch includes: raw material cleaning and conveying, crushing and filtering, sand and mud removal, and starch milk concentration and refining. During the crushing process, it is usually done by first chopping and then grinding. Existing sweet potato chopping equipment generally cannot adjust the size of the cut pieces; therefore, it is necessary to design a sweet potato chopping device for sweet potato starch preparation that can adjust the cutting size. Summary of the Invention

[0003] The purpose of this invention is to provide a sweet potato chopping device for sweet potato starch preparation, which has the advantage of being able to adjust the cutting size.

[0004] The technical solution adopted is as follows:

[0005] A sweet potato chopping device for sweet potato starch preparation includes a support frame with a feeding hopper on the support frame. A conveying pipe is horizontally arranged at the lower end of the feeding hopper, and a conveying screw is installed inside the conveying pipe. A chopping cylinder is connected to the end of the conveying pipe. A telescopic rod is vertically arranged at the upper end of the chopping cylinder. A piston block 18 connected to the telescopic rod is vertically slidably arranged inside the chopping cylinder. A cutting screen is detachably arranged inside the chopping cylinder below the conveying pipe. A box is arranged at the lower end of the chopping cylinder, and a blade is rotatably arranged inside the box. The blade is arranged below the cutting screen. A rotating mechanism connected to the blade is arranged at the upper end of the box, and a discharge pipe is arranged at the lower end of the box.

[0006] Preferably, an annular groove is provided inside the shredding cylinder above the conveying pipe, and multiple nozzles are provided inside the annular groove. A water supply ring connected to each nozzle is provided on the outside of the shredding cylinder, and a water supply mechanism connected to the water supply ring is provided on the support.

[0007] Preferably, a reducer is provided at the upper end of the housing. The reducer includes an input shaft and an output shaft. The input shaft is connected to a rotating mechanism, and the output shaft is connected to a pusher screw, which is inserted into the discharge pipe.

[0008] Preferably, the rotating mechanism is a variable frequency motor.

[0009] Compared to existing technologies, the advantages are:

[0010] The sweet potatoes are fed into the chopping cylinder by a conveying screw. The telescopic rod controls the piston to press down and use the cutting screen to cut the sweet potatoes into strips. The rotating blades below the cutting screen cut the strips into small pieces. By changing the cutting screen with different aperture and the blade speed, the sweet potatoes can be divided into small pieces of different sizes, making it highly versatile.

A telescopic rod 7 is vertically installed at the upper end of the chopping cylinder 6. A piston block 18 connected to the telescopic rod 7 is vertically slidably installed inside the chopping cylinder 6. The telescopic rod 7 controls the piston block 18 to rise and fall inside the chopping cylinder 6. A cutting mesh 8 is detachably installed inside the chopping cylinder 6 below the feeding pipe 3. Sweet potatoes entering the chopping cylinder 6 from the feeding pipe 3 fall onto the cutting mesh 8.

[0018] The lower end of the chopping cylinder 6 is equipped with a box body 9, and a blade 10 is rotatably mounted inside the box body 9. The blade 10 is positioned below the cutting screen 8. The upper end of the box body 9 is equipped with a rotating mechanism 11 connected to the blade 10, and the lower end of the box body 9 is equipped with a discharge pipe 12. The rotating blade 10 below the cutting screen 8 cuts the strip-shaped sweet potato into small pieces. By changing the cutting screen 8 with different aperture and the rotation speed of the blade 10, the sweet potato can be divided into small pieces of different sizes, making it convenient to divide the sweet potato into pieces of different sizes according to different needs.

[0019] Example 2: A sweet potato chopping device for sweet potato starch preparation includes a support 1, a feeding hopper 2 on the support 1, a conveying pipe 3 horizontally arranged at the lower end of the feeding hopper 2, a conveying screw 4 arranged inside the conveying pipe 3, the conveying screw 4 extending into the interior of the feeding hopper 2, a drive mechanism 5 arranged on the outside of the feeding hopper 2, the drive mechanism 5 having a transmission shaft connected to the conveying screw 4, the sweet potatoes fed into the feeding hopper 2 enter the conveying pipe 3 under the action of the conveying screw 4, the opening and closing of the drive mechanism 5 determines whether to convey the sweet potatoes, and the conveying speed of the sweet potatoes is adjusted by adjusting the rotation speed of the drive mechanism 5.

[0020] The end of the feeding pipe 3 is connected to a chopping cylinder 6, which is a vertically extending cylinder. A telescopic rod 7 is vertically installed at the upper end of the chopping cylinder 6. A piston block 18 connected to the telescopic rod 7 is vertically slidably installed inside the chopping cylinder 6. The telescopic rod 7 controls the piston block 18 to rise and fall inside the chopping cylinder 6. A cutting mesh 8 is detachably installed inside the chopping cylinder 6 below the feeding pipe 3. Sweet potatoes entering the chopping cylinder 6 from the feeding pipe 3 fall onto the cutting mesh 8.

The input shaft is connected to the rotating mechanism 11, and the output shaft is connected to a pusher screw 13. The pusher screw 13 is inserted into the discharge pipe 12. The reducer 14 reduces the speed of the rotating mechanism 11 and uses the pusher screw 13 to discharge material into the housing 9, thereby reducing the occurrence of material blockage in the housing 9.

[0024] The working principle is as follows:

[0025] Sweet potatoes are placed in the feed hopper 2, the drive mechanism 5 is started to drive the conveying screw 4 to rotate, and the piston block 18 is raised to a position higher than the conveying pipe 3. The sweet potatoes are then conveyed into the chopping cylinder 6 to a height no higher than the conveying pipe 3. After that, the drive mechanism 5 is turned off, and the telescopic rod 7 controls the piston block 18 to press down. The cutting mesh 8 is used to cut the sweet potatoes into strips. The rotating blade 10 below the cutting mesh 8 cuts the strips of sweet potatoes into small pieces, which are then discharged from the discharge pipe 12 under the action of the pusher screw 13. Then, the piston block 18 is raised, and the drive mechanism 5 is started to continue to convey the sweet potatoes into the chopping cylinder 6. When the chopping cylinder 6 needs to be cleaned, when the piston block 18 is higher than the nozzle 15, the water supply mechanism 17 supplies water to the water supply ring 16, and the nozzle 15 sprays water to rinse the inside of the chopping cylinder 6.
