Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and more specifically, to a special milling and sieving anti-clogging device for gorgon fruit flour. Background Technology

[0002] Gorgon fruit is an aquatic plant fruit rich in starch, protein, and various nutrients. Processing it into flour is a common deep-processing method. In the production process of gorgon fruit flour, the dried gorgon fruit granules need to be ground into powder first, and then sieved to obtain flour products of a specified fineness.

[0003] In the existing process of grinding and screening gorgon fruit, due to the high starch content of gorgon fruit, it is easy to gelatinize due to heat generated by mechanical friction during grinding, which in turn produces stickiness. As a result, the powder easily adheres to and clogs the mesh when passing through the screen. Traditional screening devices rely solely on mechanical vibration to screen the material, which has limited effectiveness in preventing sticky powder from clogging, thus affecting the production efficiency of gorgon fruit powder.

[0004] Based on this, a special milling and sieving anti-clogging device for gorgon fruit flour is proposed. Summary of the Invention

[0005] The main objective of this invention is to provide a special milling and sieving anti-clogging device for gorgon fruit flour, so as to overcome the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a special milling and sieving anti-clogging device for gorgon fruit flour, comprising a support platform, a milling chamber fixedly installed through one side of the upper surface of the support platform, cooling chambers fixedly connected to the middle of both sides of the outer surface of the milling chamber, a fan fixedly installed on the other side of the outer surface of the cooling chamber, the air inlet of the fan extending through the cooling chamber and into it, a sieving chamber provided below the milling chamber, an assembly groove fixedly installed on the upper part of the inner surface of the sieving chamber, a sieve bucket assembly being rotatably mounted on the sieving chamber through the inner surface of the assembly groove, and telescopic sleeve rods fixedly installed on all four sides of the middle of the inner surface of the sieving chamber, with a compression spring movably sleeved on the outer surface of the telescopic sleeve rod near the sieve bucket assembly.

[0007] As a further improvement of the present invention, a motor is fixedly installed on the other side of the upper surface of the support platform, a cap is fixedly connected to the upper surface of the grinding chamber, a guide frame is provided through the support platform on the lower surface of the grinding chamber, grinding rollers are rotatably inserted and installed on both sides of the inner surface of the grinding chamber, the grinding rollers are fitted together, a gear is provided at the end of the grinding rollers near the motor, two sets of gears are meshed together, the output end of the motor is fixedly connected to one set of gears, and the upper surface of the screening chamber is fixedly connected to the lower surface of the guide frame.

[0008] As a further improvement of the present invention, an inverted conical guide plate is fixedly installed on the lower surface of the screening chamber, a motor is fixedly installed on the lower part of the inner surface of the screening chamber, the output end of the motor passes through the guide plate and is fixedly connected to the lower surface of the screen assembly, and a discharge port is provided on the lower part of the four sides of the outer surface of the screening chamber, and the discharge port is flush with the lower surface of the guide plate.

[0009] As a further improvement of the present invention, the sieve bucket assembly is composed of multiple sets of sieve discs stacked vertically in a conical shape, the diameter of the sieve bucket assembly gradually decreases from top to bottom, and arc-shaped adjusting blocks are fixedly installed on all four sides of the outer surface of the sieve bucket assembly.

[0010] As a further improvement of the present invention, the telescopic sleeve is composed of two sets of sleeve structures superimposed. The diameter of the sleeve at the end of the telescopic sleeve near the screen bucket assembly is smaller than the diameter of the sleeve at the end near the screening chamber. A smooth steel ball is provided at the end of the telescopic sleeve near the screen bucket assembly.

[0011] The beneficial effects of this invention are: This invention sets the sieving structure into a cone shape composed of multiple sets of vertically stacked sieve discs, which can perform diversion sieving of gorgon fruit powder. It also uses centrifugal force to swing the sieve and assist in vibration impact, which improves the sieving effect while avoiding the problem of gorgon fruit powder clogging the sieve holes, thus improving the sieving efficiency of gorgon fruit powder. This invention uses air cooling to effectively dissipate the heat generated by the friction between the gorgon fruit and the grinding components during the grinding process, thereby preventing the gelatinization of the gorgon fruit powder and reducing its stickiness. This allows the powder to pass smoothly through the sieve holes, reducing the phenomenon of powder adhesion and clogging of the sieve holes. At the same time, the air cooling process can also separate the powder from the grinding components during the grinding process, thereby reducing powder residue. Attached Figure Description

[0016] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the invention described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0017] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0018] Please see Figures 1-6As shown, a special milling and sieving anti-clogging device for gorgon fruit flour includes a support platform 1. A milling chamber 2 is fixedly installed through one side of the upper surface of the support platform 1, and a motor 101 is fixedly installed on the other side of the upper surface of the support platform 1. A cap 103 is fixedly connected to the upper surface of the milling chamber 2. A guide frame 102 is provided through the support platform 1 on the lower surface of the milling chamber 2. Grinding rollers 201 are rotatably inserted and installed on both sides of the inner surface of the milling chamber 2. The grinding rollers 201 are fitted together and are close to the motor 101. One end of the grinding chamber 1 is provided with a gear 202, and the two sets of gears 202 are arranged in a meshing manner. The output end of the motor 101 is fixedly connected to one of the sets of gears 202. Cooling chambers 203 are fixedly connected to the middle of both sides of the outer surface of the grinding chamber 2. A fan 204 is fixedly installed on the other side of the outer surface of the cooling chamber 203. The air inlet end of the fan 204 extends through the cooling chamber 203 and into it. A screening chamber 3 is provided below the grinding chamber 2. The upper surface of the screening chamber 3 is fixedly connected to the lower surface of the guide frame 102.

[0019] It should be noted that the grinding of the water chestnut is carried out by the grinding chamber 2. The motor 101 drives one set of grinding rollers 201 to rotate clockwise. Since the two sets of grinding rollers 201 are fitted together and the end near the motor 101 is provided with gears 202 that are in a meshing state, the clockwise rotation of one set of grinding rollers 201 can drive the other set of grinding rollers 201 to rotate counterclockwise, thereby realizing the mutual grinding of the two sets of grinding rollers 201 to grind the water chestnut.

[0020] Secondly, the two sets of grinding rollers 201 generate grinding heat when grinding the gorgon fruit. At this time, the grinding rollers 201 can be cooled down by the cooling chamber 203 to reduce the grinding heat and avoid the gelatinization of the gorgon fruit powder. The fan 204 filters and extracts the external air, and the extracted air is quickly introduced into the cooling chamber 203. When the grinding rollers 201 roll through the cooling chamber 203, they can be cooled by the flowing air. During the air cooling process, the grinding rollers 201 need to be positioned diagonally above the cooling chamber 203 to avoid the phenomenon of powder being carried by the airflow and splashing randomly. When the grinding rollers 201 are positioned diagonally above the cooling chamber 203, the cooling chamber 203 only cools the bottom area of ​​the grinding rollers 201. At the same time, since the cap 103 is a bag-shaped structure, it can further block and cover the powder in the grinding chamber 2 to prevent the powder from being scattered to the outside of the grinding chamber 2 by the airflow.

[0021] A conical guide plate 301 is fixedly installed on the lower surface of the screening chamber 3. A motor 302 is fixedly installed on the lower part of the inner surface of the screening chamber 3. Drainage ports 303 are opened through the lower part of the four sides of the outer surface of the screening chamber 3. The drainage ports 303 are flush with the lower surface of the guide plate 301. An assembly groove 304 is fixedly installed on the upper part of the inner surface of the screening chamber 3. The screening chamber 3 is rotatably mounted with a screen bucket assembly 5 through the inner surface of the assembly groove 304. The output end of the motor 302 passes through the guide plate 301 and is fixedly connected to the lower surface of the screen bucket assembly 5. The screen bucket assembly 5 is composed of multiple sets of screen discs stacked vertically in a conical shape. The diameter of the screen bucket assembly 5 gradually decreases from top to bottom. An arc-shaped adjusting block 501 is fixedly installed on the four sides of the outer surface of the screen bucket assembly 5.

[0022] It should be noted that the gorgon fruit powder ground in the grinding chamber 2 can enter the sieve bucket assembly 5 set in the sieving chamber 3 through the guide frame 102. Since the sieve bucket assembly 5 is composed of multiple sets of sieve discs stacked vertically in a conical shape, it can achieve the effect of diverting and sieving the gorgon fruit powder, thereby avoiding the problem of subsequent powder not being able to pass smoothly due to blockage in a certain area of ​​powder sieving.

[0023] When the sieve assembly 5 divides and sieves the powder, the motor 302 can be started to control the sieve assembly 5 to rotate. At this time, the rotating sieve assembly 5 can achieve the effect of centrifugal swirl sieving, thereby improving the sieving efficiency of the powder. The sieved powder can enter the sieving chamber 3 and fall onto the guide plate 301. Since the guide plate 301 is set in the shape of an inverted funnel, the falling powder can automatically flow along the inclined surface of the guide plate 301 to the discharge port 303 to be discharged and the sieving is completed.

[0024] Telescopic sleeve rods 4 are fixedly installed on all four sides of the inner surface of the screening chamber 3. A compression spring 401 is movably installed on the outer surface of the end of the telescopic sleeve rod 4 near the screen bucket assembly 5. The telescopic sleeve rod 4 is composed of two sets of sleeve structures superimposed. The diameter of the sleeve at the end of the telescopic sleeve rod 4 near the screen bucket assembly 5 is smaller than the diameter of the sleeve at the end near the screening chamber 3. A smooth steel ball is provided at the end of the telescopic sleeve rod 4 near the screen bucket assembly 5.

[0025] It should be noted that since the sieve bucket assembly 5 is in a rotating sieve state during the sieve process, the rotation of the sieve bucket assembly 5 will drive the adjusting block 501 to rotate synchronously. Since the adjusting block 501 is convex relative to the sieve bucket assembly 5, when the rotating adjusting block 501 contacts the telescopic sleeve rod 4, it can reduce the extension distance of the telescopic sleeve rod 4, thereby pressing the telescopic sleeve rod 4 to retract. At this time, the telescopic sleeve rod 4 is in a retracted state, which can drive the compression spring 401 to undergo elastic deformation. When the adjusting block 501 rotates away and no longer contacts the telescopic sleeve rod 4, the extension distance of the telescopic sleeve rod 4 expands, thereby releasing the compression deformation state of the compression spring 401. The compression spring 401 can then elastically rebound, driving the telescopic sleeve rod 4 to extend and control the smooth steel ball to impact the sieve bucket assembly 5, thereby achieving the effect of oscillation and impact to loosen the powder in the sieve holes of the sieve bucket assembly 5, and further improve the sieve efficiency of the powder passing through the sieve bucket assembly 5.

[0026] When using this invention, the gorgon fruit can first be poured into the grinding chamber 2, and the grinding roller 201 is driven by the motor 101 to grind the gorgon fruit. During the grinding process, the fan 204 is started to filter and extract the external air. The extracted air is quickly fed into the cooling chamber 203. When the grinding roller 201 rolls through the cooling chamber 203, it can be cooled by the flowing air to reduce the grinding heat and avoid the gelatinization of the gorgon fruit powder. The gorgon fruit powder ground in the grinding chamber 2 can enter the sieve bucket assembly 5 set in the sieving chamber 3 through the guide frame 102. The sieve bucket assembly 5 is used to divide the gorgon fruit powder. At this time, the motor 302 can be started to control the sieve bucket assembly 5 to rotate. The rotating sieve bucket assembly 5 can centrifugally sieving the gorgon fruit powder. Simultaneously, the rotation of the sieve bucket assembly 5 will drive the adjusting block 501 to rotate synchronously. When the rotating adjusting block 501 contacts the telescopic sleeve rod 4, it can press the telescopic sleeve rod 4 to retract. At this time, the telescopic sleeve rod 4 is in a retracted state, which can drive the compression spring 401 to undergo elastic deformation. When the adjusting block 501 rotates away and no longer contacts the telescopic sleeve rod 4, the extension distance of the telescopic sleeve rod 4 increases, thereby releasing the compression deformation state of the compression spring 401. The compression spring 401 can then elastically rebound, driving the telescopic sleeve rod 4 to extend and control the smooth steel ball to impact the sieve bucket assembly 5, thereby achieving the effect of oscillation and impact to loosen the powder in the sieve holes of the sieve bucket assembly 5, further improving the sieving efficiency of the powder through the sieve bucket assembly 5. The sieved powder can enter the sieve chamber 3 and fall onto the guide plate 301. Since the guide plate 301 is set in the shape of an inverted funnel, the falling powder can automatically flow along the inclined surface of the guide plate 301 to the discharge port 303 for discharge.

[0027] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
