Description

Technical Field

[0001] This utility model relates to the field of agglomeration treatment technology, specifically to screening equipment for resistant starch production. Background Technology

[0002] Resistant starch, also known as enzyme-resistant starch or indigestible starch, cannot be broken down by enzymes in the small intestine, but it can undergo fermentation with volatile fatty acids in the colon. Resistant starch is found in some natural foods, such as potatoes, bananas, and rice, with corn starch, especially high in amylose, containing up to 60% resistant starch. This type of starch is more difficult to degrade than other starches, digesting and absorbing slowly into the bloodstream. Its properties are similar to soluble fiber, offering some slimming effects, and it has become increasingly popular among those concerned with weight loss in recent years. Resistant starch resists enzymatic breakdown, releasing glucose slowly in the body, resulting in a lower insulin response, which helps control blood sugar balance and reduce hunger, making it particularly suitable for diabetics.

[0003] During the preparation of resistant starch, the starch is prone to clumping, which can affect subsequent processing and reduce the quality of the resistant starch.

[0004] The prior art discloses a solution with publication number CN214950146U, which includes a filtration mechanism. The filtration mechanism includes a filter box, and a drying mechanism is fixedly installed at the bottom of the filter box. By setting the filtration mechanism in the drying equipment, and setting the filter plate with through holes in the filter mechanism, a cylinder can drive a rack plate to slide back and forth in a limiting groove, thereby driving a cylindrical gear to reciprocate. This drives a spur gear to rotate through a rotating shaft, which in turn drives a spur gear to rotate. The spur gear drives a second spur gear, which in turn drives the filter plate to reciprocate. This allows the repeatedly swinging filter plate to filter out the lumpy starch in the resistant starch, thereby preventing the moisture-induced lumps of resistant starch from adhering to the inner wall of the drying box. Furthermore, the swinging filter plate can gradually disperse the lumps of resistant starch, allowing it to be dried by the drying mechanism.

[0005] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0006] First, during the processing of resistant starch, the particle size of the starch after agglomeration varies, making it impossible for existing equipment to select and use resistant starch with different particle sizes, thus reducing the processing efficiency of resistant starch.

[0007] Secondly, the existing resistant starch that has clumped is limited by the crushing structure during processing, which makes it impossible to crush the clumped starch quickly, thus affecting the crushing efficiency of the clumped starch.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a screening device for resistant starch production. This device solves the problem that, during the processing of resistant starch in traditional technologies, the different particle sizes of the starch after agglomeration prevent existing devices from selecting and using resistant starch of different particle sizes, thus reducing the processing efficiency of resistant starch.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A screening device for resistant starch production includes a feeding shell, a semi-circular shell at the bottom of the feeding shell, a material-dispensing blade that rotates horizontally inside the semi-circular shell and rubs against its inner surface, and material leakage holes evenly distributed on the arc-shaped wall of the semi-circular shell. A discharge shell covering the material leakage holes is fixedly connected to the outside of the feeding shell. A cylindrical screening cylinder shell is fixedly connected to the lower end of the discharge shell. A rectangular feed inlet communicating with the discharge shell is opened at the upper end of the screening cylinder shell. A screening cylinder that rotates coaxially inside the screening cylinder shell and rubs against its inner wall is provided. Several screen hole areas with different mesh sizes are arranged around the circumference of the screening cylinder.

[0012] As an optimized solution, one end of the screening cylinder shell is open, and a receiving shell is fixedly positioned inside the screening cylinder. The upper end of the receiving shell is open and located below the uppermost screen hole area. The discharge end of the receiving shell extends to the outside of the screening cylinder shell.

[0013] As an optimized solution, a collection shell is fixedly connected to the lower end outer wall of the screening cylinder shell, and a cleaning hole communicating with the collection shell is opened at the lower end of the screening cylinder shell.

[0014] As an optimized solution, a cavity shell is horizontally provided inside the screening cylinder near the inner bottom surface, and a number of blow nozzles facing the cleaning holes are evenly distributed on the lower surface of the cavity shell.

[0015] As an optimized solution, connecting rods are fixedly connected side by side to the upper surface of the cavity shell, and the upper end of the connecting rods is fixedly connected to the outer bottom surface of the receiving shell.

[0016] As an optimized solution, a turntable is fixedly connected to the inner end of the screening cylinder, and a drive motor is fixedly connected to the outer end wall of the screening cylinder. The output shaft of the drive motor is fixedly connected to the center position of the turntable.

[0017] As an optimized solution, the feeding blade includes a horizontally rotating shaft, and a plurality of feeding plates are fixedly attached to the shaft. The outer ends of the feeding plates are in frictional contact with the arc-shaped inner wall of the semi-circular shell.

[0018] As an optimized solution, a motor is fixedly connected to the outer end wall of the semi-circular shell, and the motor is fixedly connected to one end of the rotating shaft.

[0019] As an optimized solution, a material collection hopper is fixedly connected to the upper end of the feed housing.

[0020] As an optimized solution, a high-pressure air inlet cylinder communicating with the inner cavity is fixedly connected to the outer end of the cavity shell.

[0021] As an optimized solution, the lower end of the collection shell is provided with a discharge section arranged in a funnel shape.

[0022] As an optimized solution, the inner bottom surface of the receiving shell is inclined downwards towards the discharge end.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The resistant starch that clumps is poured into the hopper and enters the bottom of the semi-circular shell. The powder will fall into the discharge shell through the discharge hole. Under the action of the feeding blades, the clumps move with the feeding blades, and the clumps rub against the inner wall of the semi-circular shell and the feeding blades, so as to gradually crush them into powder. The powder then falls into the discharge shell through the discharge hole, thus crushing the clumps.

[0025] By aligning sieves with different mesh sizes toward a rectangular feed inlet, resistant starch is sieved according to particle size. The resistant starch that passes through the sieves falls into the collection shell. Due to the inclined bottom of the collection shell, the resistant starch is discharged.

[0026] The bottom of the screening cylinder shell has a cleaning hole, and the cavity shell is set above the screen hole area, so that high-pressure air can be introduced to reverse the blowing of particles trapped in the screen hole area. The blown particles fall into the collection shell and are discharged through the discharge section, which is convenient and fast. Attached Figure Description

Detailed Implementation

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0032] like Figure 1 and Figure 2 As shown, the screening equipment for resistant starch production includes a feeding shell 1, a semi-circular shell 3 at the bottom of the feeding shell 1, a material-dispensing blade 4 that rotates horizontally inside the semi-circular shell 3 and rubs against its inner surface, and material leakage holes evenly distributed on the arc-shaped wall of the semi-circular shell 3. A discharge shell 2 covering the material leakage holes is fixedly connected to the outside of the feeding shell 1. A cylindrical screening cylinder shell 8 that is horizontally arranged is fixed to the lower end of the discharge shell 2 through a tapered section. A rectangular feed inlet 6 that communicates with the discharge shell 2 is opened at the upper end of the screening cylinder shell 8. A screening cylinder 7 that rotates coaxially inside the screening cylinder shell 8 and rubs against its inner wall is provided. Several screen hole areas 9 with different mesh sizes are arranged around the circumference of the screening cylinder 7.

[0033] The screening cylinder shell 8 has an opening at one end. Inside the screening cylinder 7, there is a material receiving shell 10 that is fixedly positioned. The upper end of the material receiving shell 10 is open and located below the uppermost screen hole area 9. The discharge end of the material receiving shell 10 extends to the outside of the screening cylinder shell 8.

[0034] A collection shell 14 is fixedly connected to the outer wall of the lower end of the screening cylinder shell 8, and a cleaning hole 13 communicating with the collection shell 14 is opened at the lower end of the screening cylinder shell 8.

[0035] Inside the screening cylinder 7, near the bottom, there is a horizontal cavity shell 11. The lower surface of the cavity shell 11 is evenly distributed with several blow nozzles 12 facing the cleaning holes 13.

[0036] A connecting rod 15 is fixedly connected in parallel to the upper surface of the cavity shell 11, and the upper end of the connecting rod 15 is fixedly connected to the outer bottom surface of the receiving shell 10.

[0037] A turntable 16 is fixedly connected to the inner end of the screening cylinder 7, and a drive motor 17 is fixedly connected to the outer end wall of the screening cylinder 7. The output shaft of the drive motor 17 is fixedly connected to the center position of the turntable 16.

[0038] A stepper motor or a servo motor can be connected to the drive motor 17, so that the controller can send pulse signals to control the number of rotation steps of the stepper motor or servo motor, thereby precisely controlling the rotation angle (each pulse corresponds to a fixed angle increment).

[0039] The feeding blade 4 includes a horizontally rotating shaft, and several feeding plates are fixedly attached to the shaft. The outer ends of the feeding plates are in frictional contact with the arc-shaped inner wall of the semi-circular shell 3.

[0040] A motor is fixedly connected to the outer end wall of the semi-circular shell 3, and the motor is fixedly connected to one end of the rotating shaft.

[0041] A material collection hopper 5 is fixedly connected to the upper end of the feed housing 1.

[0042] A high-pressure air inlet cylinder that communicates with the inner cavity is fixed to the outer end of the cavity shell 11.

[0043] The lower end of the collecting shell 14 is provided with a discharge section that is arranged in a funnel shape.

[0044] The inner bottom surface of the receiving shell 10 is tilted downwards towards the discharge end.

[0045] The working principle of this device is as follows:

[0046] The resistant starch is poured into the hopper 5 and enters the bottom of the semi-circular shell 3. The powder will fall into the discharge shell 2 through the discharge hole. The agglomerated material moves with the feeding blade 4 under the action of the feeding blade 4, and the agglomerated material rubs against the inner wall of the semi-circular shell 3 and the feeding blade 4, so as to gradually crush it into powder. The powder then falls into the discharge shell 2 through the discharge hole, thus crushing the agglomerated material.

[0047] By aligning the sieve holes 9 with different mesh sizes toward the rectangular feed inlet 6, the resistant starch is sieved according to particle size. The resistant starch that passes through the sieve holes 9 falls into the collection shell 14. Since the bottom surface of the collection shell 14 is inclined, the resistant starch is discharged.

[0048] The bottom of the screening cylinder shell 8 has a cleaning hole 13, and the cavity shell 11 is set above the screen hole area 9, so that high-pressure air can be introduced to blow the particles trapped in the screen hole area 9 in reverse. The blown particles fall into the collection shell 14 and are discharged through the discharge section, which is convenient and fast.
