Description

Technical Field

[0001] This invention relates to the field of general crushing, grinding or pulverizing technology, and in particular to a low-temperature grinding production equipment for protein powder. Background Technology

[0002] Low-temperature grinding production equipment is used to grind protein powder raw materials into fine powder while maintaining a low-temperature environment during the grinding process to prevent protein denaturation or degradation due to heat. Since the protein powder is in a low-temperature state during grinding, it is necessary to pre-cool the protein powder material with liquid nitrogen to rapidly reduce its temperature below the embrittlement point, and then pulverize it to the required fineness in the grinding production equipment. This provides technical inspiration for grinding production equipment. The research on grinding production equipment revealed the following problems: Protein powder needs to be pre-cooled at low temperature before grinding. After pre-cooling, protein powder is prone to clumping. Therefore, grinding equipment needs to grind the protein powder for a long time. At the same time, grinding equipment usually feeds the material directly into the grinding mechanism, which can easily cause protein powder to accumulate. This makes it impossible for the grinding equipment to perform preliminary grinding of the protein powder while feeding the material evenly, thus shortening the subsequent grinding time of the grinding mechanism. Currently, the prior art CN202311314363.8, a grinding device for processing walnut protein powder, discloses a grinding device. This invention has a support leg fixedly connected to the bottom of the housing, a feeding bin installed at the top of the housing, a pair of crushing rollers rotatably connected to the top of the housing, a power component for driving the crushing rollers to rotate installed on the outside of the housing, a first cleaning component for cleaning the crushing rollers installed inside the housing, a receiving bin fixedly connected to the bottom of the crushing rollers inside the housing, a grinding mechanism installed at the bottom of the receiving bin inside the housing, and a discharge pipe at the bottom of the housing. First, the walnut kernels are initially crushed by the crushing rollers, then the crushed walnut kernels are ground by the grinding rollers. The ground walnut powder is discharged through a filter screen. The entire process, involving crushing and grinding, makes the ground walnut powder more uniform in particle size. Furthermore, the crushing and grinding rollers can be cleaned simultaneously during the grinding process to prevent walnut powder from adhering to them and affecting the grinding effect. This invention primarily addresses the problem that grinding production equipment cannot perform preliminary grinding of protein powder while feeding it evenly. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a low-temperature grinding production equipment for protein powder, thereby resolving the issues described in the background section.

[0004] The purpose and effect of the low-temperature grinding production equipment for protein powder of the present invention are achieved by the following specific technical means: a low-temperature grinding production equipment for protein powder includes a shell, a motor is provided on the side of the shell, the motor is rotatably connected to a grinding roller through an output shaft, a sealing door is rotatably connected to the upper end of the shell near the grinding roller, and a hopper is provided at the upper end of the sealing door.

[0005] Furthermore, the grinding roller is rotatably installed inside the housing, and a feed inlet extends through the inside of the sealed door, communicating with the lower end of the hopper.

[0006] Furthermore, the hopper is used in conjunction with a feeder, allowing protein powder to continuously fall into the hopper.

[0007] Furthermore, the motor is connected to the power circuit via a power cord, and the motor drives the grinding roller to rotate 360°.

[0008] Furthermore, the hopper has a bearing that rotates through it, and a material tray surrounds the outside of the bearing.

[0009] Furthermore, the material tray is provided with 3 or 5 trays, and the interior of the tray has through holes with a diameter of 0.3-0.5 cm.

[0010] Furthermore, the tray has an internal track, and a sliding rod is slidably nested inside the track, with a protrusion at one end of the sliding rod.

[0011] Furthermore, the track is circular in shape, and a groove is provided inside the track, which is also circular in shape.

[0012] Furthermore, both ends of the slide rod extend into the interior of the track groove, and the slide rod slides 360° inside the track. The slide rod is matched with the convex strip.

[0013] Furthermore, the ridges are arranged vertically and extend to the outside of the track.

[0014] Furthermore, a disc slides on the upper end of the track, a sleeve is connected through the upper end of the disc, a rotating shaft is rotatably connected to the upper end of the sleeve, a lever is provided at the lower end of the rotating shaft, and side plates are oscillatingly connected to both sides of the upper end of the rotating shaft.

[0015] Furthermore, the disc has holes extending through its interior and the lower end of the sleeve, the paddle is located inside the hole in the sleeve, and the protrusion extends through the hole in the disc into the hole in the sleeve.

[0016] Furthermore, the lower end of the disc is attached to the end of the track, and the disc is spaced 1-2 cm from the inner wall of the material tray.

[0017] Furthermore, the lower end of the paddle is provided with a groove, and the side of the convex strip is provided with a protrusion. The protrusion and the groove of the paddle are vertically engaged and connected. The rotating shaft is linked with the slide rod through the paddle, the convex strip and the slide rod.

[0018] Furthermore, when the entire tray is facing upwards, the side plate is positioned above the disc.

[0019] Furthermore, the upper end of the side plate is provided with a groove, and the length of the side plates on both sides of the rotating shaft is spaced 1-3cm apart.

[0020] Beneficial effects: 1. The material tray uses the weight of the protein powder to assist the bearing in rotating. The entire material tray rotates inside the hopper. The rotation of the material tray helps the hopper to feed the protein powder evenly, avoiding the accumulation of protein powder inside the grinding roller, which would require the grinding roller to grind the protein powder for a long time. 2. When the entire tray rotates to the side of the bearing, the tray faces upward. The upper end of the side plate has a groove to facilitate the protein powder to fall to the upper end of the side plate. The side plates on both sides of the rotating shaft are spaced 1-3cm apart, so that the upper ends of the side plates on both sides of the rotating shaft are different in weight. The side plates assist the rotating shaft to rotate. At this time, the protein powder on the upper end of the side plate on one side of the rotating shaft falls downward, causing the side plate on the other side of the rotating shaft to swing downward, which facilitates the rotating shaft to swing in a reciprocating vertical direction. 3. When the shaft rotates, it drives the paddle to swing synchronously. The paddle and the convex strip are engaged in a perpendicular direction. The paddle can drive the slide rod to reciprocate through the convex strip. Through the reciprocating rotation of the slide rod, the slide rod can rub against the inside of the track, which facilitates the movement of the slide rod inside the track. By tilting the track during the tilting rotation of the material tray, it can assist the slide rod in driving the disc to move. The disc slides around the end of the track, so the disc can perform preliminary grinding of the protein powder inside the material tray. This allows the grinding equipment to perform synchronous grinding of the protein powder inside the material tray during the process of forming a uniform feeding, avoiding the situation where the grinding roller needs to grind the protein powder for a long time after the protein powder is pre-cooled and agglomerated by liquid nitrogen.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0031] As attached Figure 1 To be continued Figure 8 As shown: Example 1: A low-temperature grinding production equipment for protein powder includes a housing 1. A motor 101 is provided on the side of the housing 1. The motor 101 is rotatably connected to a grinding roller 103 via an output shaft. A sealing door 104 is rotatably connected to the upper end of the housing 1 near the grinding roller 103. A hopper 102 is provided at the upper end of the sealing door 104. The grinding roller 103 is rotatably mounted inside the housing 1. A feed inlet extends through the interior of the sealing door 104, communicating with the lower end of the hopper 102. (Refer to the attached instruction manual for details.) Figure 2 As shown; The hopper 102 is used in conjunction with the feeder, so that the protein powder can continuously fall into the hopper 102. The feeder is a protein powder feeder; Motor 101 is connected to the power circuit via a power cord, and motor 101 drives grinding roller 103 to rotate 360°. The hopper 102 has a rotating bearing 2 inside, and a material tray 201 surrounds the outside of the bearing 2. The material tray 201 has 3 or 5 trays, and the interior of the material tray 201 has through holes with a diameter of 0.3-0.5cm. In this process: after being frozen by liquid nitrogen, the protein powder is filled into the hopper 102 by the feeder. The protein powder falls to the upper end of the tray 201. Due to the weight of the protein powder, the tray 201 swings downward through the bearing 2. Since the tray 201 surrounds the outside of the bearing 2, the above steps are repeated. The bearing 2 can rotate 360° using the weight of the protein powder. The inside of the sealing door 104 has a feed inlet that is connected to the lower end of the hopper 102. The protein powder enters the upper part of the housing 1 through the hopper 102. The motor 101 drives the grinding roller 103 to rotate through the output shaft. The grinding roller 103 can perform low-temperature grinding on the protein powder. Example 2: Refer to the attached instruction manual Figure 4-8 It can be seen that the difference between Embodiment 2 and Embodiment 1 is that the tray 201 is provided with a track 3 inside, and a sliding rod 301 is slidably nested inside the track 3. One end of the sliding rod 301 is provided with a protrusion 302. Among them: Track 3 is circular in shape, and a groove is formed inside Track 3. The groove is circular in shape. Please refer to the instruction manual for details. Figure 6 As shown; Both ends of the slide rod 301 extend into the interior of the slide groove of the track 3. The slide rod 301 slides 360° inside the track 3. The slide rod 301 is matched with the protrusion 302. The two ends of the slide bar 301 extend into the interior of the slide groove of the track 3, which can prevent the track 3 and the slide bar 301 from being located at the lower end of the track 3 when the material tray 201 swings downward through the bearing 2. The protrusions 302 are arranged vertically and extend to the outside of the track 3; During the rotation of the material tray 201 via the bearing 2, the track 3 rotates synchronously at an inclination. Due to the inclination of the track 3, the slide rod 301 slides inside the track 3, and the slide rod 301 slides synchronously with the protrusion 302. Example 3: Refer to the attached instruction manual Figure 4-8 It can be seen that the difference between Embodiment 3 and Embodiments 1 and 2 is that a disc 4 slides on the upper end of the track 3, a sleeve 401 is connected through the upper end of the disc 4, a rotating shaft 402 is rotatably connected through the upper end of the sleeve 401, a paddle 403 is provided at the lower end of the rotating shaft 402, and side plates 404 are oscillatingly connected to both sides of the upper end of the rotating shaft 402. Specifically: The disc 4 has a through hole at its interior and the lower end of the sleeve 401; the paddle 403 is located inside the hole in the sleeve 401; and the protrusion 302 extends through the hole in the disc 4 into the hole in the sleeve 401. (Refer to the attached instruction manual for details.) Figure 7 As shown; The lower end of the disc 4 is attached to the end of the track 3, and the disc 4 is spaced 1-2 cm from the inner wall of the material tray 201; The disc 4 is spaced 1-2cm from the inner wall of the material tray 201. When the disc 4 slides, it facilitates the initial grinding of the protein powder inside the material tray 201 by the disc 4. The lower end of the paddle 403 is provided with a groove, and the side of the convex strip 302 is provided with a protrusion. The protrusion and the groove of the paddle 403 are vertically engaged and connected. The rotating shaft 402 is linked with the slide rod 301 through the paddle 403, the convex strip 302 and the slide rod 301. By engaging the protrusion with the groove of the lever 403, when the entire tray 201 is facing downwards, the disc 4 can be prevented from falling downwards from the lower end of the track 3, thereby achieving the effect of limiting the position of the disc 4. When the tray 201 is facing upwards, the side plate 404 is above the disc 4. Please refer to the instruction manual for details. Figure 8 As shown; The upper end of the side plate 404 is provided with a groove, and the length of the side plates 404 on both sides of the rotating shaft 402 is 1-3cm apart; The upper end of the side plate 404 is provided with a groove to facilitate the protein powder to fall to the upper end of the side plate 404. The side plates 404 on both sides of the rotating shaft 402 are spaced 1-3cm apart, so that the upper ends of the side plates 404 on both sides of the rotating shaft 402 are different in weight, thereby assisting the rotating shaft 402 to rotate through the side plates 404. Among them: the material tray 201 uses the weight of the protein powder to assist the bearing 2 to rotate. The material tray 201 rotates inside the hopper 102. The rotation of the material tray 201 can assist the hopper 102 to feed the protein powder evenly, and avoid the protein powder from accumulating inside the grinding roller 103, which would cause the grinding roller 103 to grind the protein powder for a long time. When the material tray 201 rotates to the side of the bearing 2, the material tray 201 faces upward. The upper end of the side plate 404 has a groove to facilitate the protein powder to fall to the upper end of the side plate 404. The side plates 404 on both sides of the rotating shaft 402 are spaced 1-3cm apart, so that the upper ends of the side plates 404 on both sides of the rotating shaft 402 have different weights. The side plates 404 assist the rotating shaft 402 to rotate. At this time, the protein powder on the upper end of the side plate 404 on one side of the rotating shaft 402 falls downward, causing the side plate 404 on the other side of the rotating shaft 402 to swing downward, which facilitates the rotating shaft 402 to swing back and forth in a vertical direction. When the rotating shaft 402 rotates, it drives the paddle 403 to swing synchronously. The paddle 403 is vertically engaged with the convex strip 302. The paddle 403 can drive the slide rod 302 to reciprocate through the convex strip 302. Through the reciprocating rotation of the slide rod 302, the slide rod 302 can rub against the inside of the track 3, which facilitates the movement of the slide rod 302 inside the track 3. By tilting the track 3 during the tilting rotation of the material tray 201, the slide rod 302 can drive the disc 4 to move. The disc 4 slides around the end of the track 3. Therefore, the disc 4 can perform preliminary grinding on the protein powder inside the material tray 201. This allows the grinding equipment to perform synchronous grinding on the protein powder inside the material tray 201 during the process of forming a uniform feeding, avoiding the situation where the grinding roller 103 needs to grind the protein powder for a long time after the protein powder is pre-cooled and agglomerated by liquid nitrogen.
