Description

Technical Field

[0001] The invention relates to the technical field of processing protein powder of nuts such as macadamia nuts or walnuts, and in particular to a drying device for processing the protein powder of nuts. Background Art

[0002] Nut protein powder is a powder food made from nuts as raw materials. It can supplement protein for people who lack protein.

[0003] In the prior art, nut protein powder is prone to moisture during processing, so the damp nut protein powder needs to be dried. To improve the drying efficiency, the existing nut protein powder drying methods are mostly to centrally dry a batch of damp nut protein powder. However, the same batch of nut protein powder often has different moisture conditions, that is, some nut protein powders are more seriously damp, and thus have higher humidity, while some nut protein powders are less damp, and thus have lower humidity. When nut protein powders with different humidity levels are centrally dried, in order to ensure that all nut protein powders can be effectively dried, the drying time of the nut protein powder is usually relatively long. During the long drying process of all the nut protein powders, the nut protein powders that originally had lower humidity often suffer from unnecessary overdrying.

[0038] The present invention is further explained below in conjunction with specific implementation modes.

[0039] See also Figure 1 , Figure 2 and Figure 3 The present embodiment provides a drying device for processing nut protein powder, comprising a telescopic heating component 20, a material holding box 30, a scraping component 40, a load-bearing component 70 and a driving component 80. The upper end of the material holding box 30 is open, and a plurality of legs 10 are fixedly arranged on the bottom edge of the material holding box 30. A material discharge port 301 is provided on the bottom wall of the material holding box 30. A material storage barrel 302 connected to the material discharge port 301 is fixedly arranged at the bottom of the material holding box 30. The telescopic heating component 20 is arranged at the bottom of the material storage barrel 302. The scraping component 40 is provided with a plurality of groups, and the plurality of scraping components 40 are arranged in a ring-shaped manner inside the material holding box 30. The scraper assemblies 40 are arranged at intervals, and a discharge area 50 is formed between two adjacent groups of the scraper assemblies 40. The driving assembly 80 is installed at the bottom of the material storage box 30, and is used to drive a number of the scraper assemblies 40 to rotate, so as to scrape the nut protein powder in the discharge area 50 from the discharge port 301 into the storage barrel 302. One end of the load-bearing assembly 70 extends into the storage barrel 302, and the other end extends into the telescopic heating assembly 20 and is connected to the telescopic heating assembly 20. When the nut protein powder enters the storage barrel 302, the load-bearing assembly 70 is affected by the humidity of the nut protein powder to drive the telescopic heating assembly 20 to extend and retract.

[0040] When the nut protein powder is dried, the nut protein powder to be dried can be placed in the discharge area 50 in the material box 30, and the driving component 80 is used to drive the scraper component 40 to rotate. When the scraper component 40 rotates, the nut protein powder in the discharge area 50 is driven to rotate. When the nut protein powder rotates to the discharge port 301, a portion of the nut protein powder enters the storage barrel 302 through the discharge port 301, and then flows downward along the inside of the telescopic heating component 20. The telescopic heating component 20 is used to heat this portion of the nut protein powder to achieve the drying of this portion of the nut protein powder; in the above process, when a portion of the nut protein powder enters the storage barrel 302 through the discharge port 301, if this portion of the nut protein powder If the humidity of the nut protein powder is high, the weight of this part of the nut protein powder is heavier, the load-bearing component 70 is subjected to greater pressure from this part of the nut protein powder, and the load-bearing component 70 drives the telescopic heating component 20 to extend, thereby increasing the flow distance of this part of the nut protein powder inside the telescopic heating component 20 and extending the heating time of this part of the nut protein powder. Conversely, if the humidity of this part of the nut protein powder is low, the weight of this part of the nut protein powder is lighter, the pressure from this part of the nut protein powder to the load-bearing component 70 is less, and the load-bearing component 70 drives the telescopic heating component 20 to shorten, thereby reducing the flow distance of this part of the nut protein powder inside the telescopic heating component 20 and shortening the heating time of this part of the nut protein powder.

[0041] See also Figure 1 and Figure 3 In one embodiment, the driving assembly 80 includes a motor 801, a rotating shaft 802, a transmission belt 805, a first pulley 806 and a second pulley 807, the motor 801 is fixedly mounted on the bottom of the material holding box 30, the upper end of the rotating shaft 802 passes through the bottom wall of the material holding box 30 and extends to the inside of the material holding box 30, the lower end of the rotating shaft 802 is fixedly connected to the first pulley 806, the second pulley 807 is fixedly arranged at the output end of the motor 801, one end of the transmission belt 805 is sleeved on the outside of the first pulley 806, and the other end is sleeved on the outside of the second pulley 807, and several of the scraper assemblies 40 have the same structure, and all include a scraper 401 and a baffle 402, one end of the scraper 401 and the baffle 402 is fixedly connected to the side wall of the shaft body of the rotating shaft 802 located inside the material holding box 30, and the other end is attached to the inner wall of the material holding box 30, and the scraper 401 and the baffle 402 are distributed in a V shape.

[0042] After the nut protein powder to be dried is placed inside the discharge area 50, the second pulley 807 is driven to rotate by the motor 801, and the transmission action of the transmission belt 805 and the first pulley 806 drives the rotating shaft 802 to rotate, thereby driving the scraper 401 and the baffle 402 to rotate. When the scraper 401 rotates, it pushes the nut protein powder inside the discharge area 50 to rotate. When the scraper 401 pushes the nut protein powder to the top of the discharge port 301, a part of the nut protein powder enters the storage barrel 302 through the discharge port 301. As the scraper 401 continues to rotate, when the scraper 401 passes over the discharge port 301, the scraper 401 scrapes the nut protein powder in the discharge port 301 flat, and then the discharge port 301 moves relatively to the position between the scraper 401 and the baffle 402.

[0043] See also Figure 1 In one embodiment, the telescopic heating component 20 includes a first heating sleeve 201 and a second heating sleeve 202. The upper end of the second heating sleeve 202 is connected to the bottom of the storage barrel 302, and the lower end extends to the inside of the first heating sleeve 201 and is telescopically matched with the first heating sleeve 201. The inner walls of the first heating sleeve 201 and the second heating sleeve 202 are both provided with electric heating plates (not shown in the figure).

[0044] When a portion of the nut protein powder enters the storage barrel 302 through the discharge port 301, it can flow downward from the second heating sleeve 202 and the first heating sleeve 201, and the electric heating plates on the inner walls of the first heating sleeve 201 and the second heating sleeve 202 are used to heat the portion of the nut protein powder to achieve drying of the portion of the nut protein powder.

[0045] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 In one embodiment, a through opening and two groups of air holes are provided on the side wall of the material storage barrel 302, and the through opening and the two groups of air holes are respectively located on the mutually perpendicular walls of the material storage barrel 302, and the two groups of air holes are distributed up and down on the wall of the material storage barrel 302. A sealing plate 303 is hingedly provided on the outer wall of the material storage barrel 302, and the sealing plate 303 is used to seal the through opening. A rocker rod 306 is fixedly provided on the bottom edge of the sealing plate 303. A flexible limiting strip 307 is embedded in the inner wall of the material storage barrel 302, and the flexible limiting strip 307 is located on the inner sides of the two groups of air holes. Two groups of hemispherical air bags 305 are provided on the outer wall of the material storage barrel 302, and the two groups of hemispherical air bags 305 are respectively connected with the two groups of air holes, and the outer side of the rotating shaft 802 is also fixed A rotating wheel 803 is fixedly provided, and a magnet 804 is fixedly provided on the circumferential side wall of the rotating wheel 803. The sealing plate 303 is made of iron material. The load-bearing component 70 includes a load-bearing plate 701, a load-bearing rod 702 and a second elastic member 703. The load-bearing plate 701 is movably arranged inside the storage barrel 302. The upper surface of the load-bearing plate 701 is an inclined structure. The upper end of the load-bearing rod 702 is connected to the bottom of the load-bearing plate 701, and the lower end passes through the second heating sleeve 202 and extends to the inside of the first heating sleeve 201. The bottom of the load-bearing rod 702 is connected to the inner wall of the first heating sleeve 201 through a connecting rod 705. The second elastic member 703 is arranged inside the storage barrel 302 to provide elastic support for the load-bearing plate 701.

[0046] When the nut protein powder has not entered the storage barrel 302, the load-bearing plate 701 is stationary at a certain position inside the storage barrel 302. At this time, the sealing plate 303 is attached to the outer wall of the storage barrel 302 to seal the opening. At the same time, the swing rod 306 acts on a group of hemispherical air bags 305 below and squeezes the group of hemispherical air bags 305. When the hemispherical air bags 305 are compressed, the flexible limiting strips 307 are driven to expand into the storage barrel 302, thereby pressing the side wall of the load-bearing plate 701 to limit the load-bearing plate 701. When the scraper 401 pushes a part of the nut protein powder through After being scraped into the storage barrel 302 from the discharge port 301, this part of the nut protein powder falls on the upper part of the load-bearing plate 701, and then the scraper 401 passes over the discharge port 301 to scrape the nut protein powder inside the storage barrel 302 and the discharge port 301 flat, and at the same time, the rotating shaft 802 drives the rotating wheel 803 to rotate, so that the magnet 804 on the circumferential side wall of the rotating wheel 803 rotates to the side of the sealing plate 303, and the sealing plate 303 is driven to rotate relative to the outer wall of the storage barrel 302 by the attraction of the magnet 804 to the sealing plate 303, thereby opening the through port, and the sealing plate 303 When the swing rod 306 rotates, it drives the swing rod 306 to rotate upward. When the swing rod 306 rotates upward, the squeezing state of the hemispherical air bag 305 below is released, and the hemispherical air bag 305 below expands, thereby attracting the flexible limit strip 307 to shrink, so as to release the limit on the load-bearing plate 701. At this time, if the nut protein powder entering the storage barrel 302 has a high humidity, the weight of this part of the nut protein powder is large, and the weight of this part of the nut protein powder overcomes the supporting force of the second elastic member 703, thereby driving the load-bearing plate 701 to move downward along the inside of the storage barrel 302. When the load-bearing plate 701 moves downward, The load-bearing rod 702 and the connecting rod 705 drive the first heating sleeve 201 to move downward and extend compared with the second heating sleeve 202. On the contrary, if the nut protein powder entering the storage barrel 302 has a low humidity, the weight of this part of the nut protein powder is relatively light, and this part of the nut protein powder is insufficient to overcome the supporting force of the second elastic member 703. The second elastic member 703 pushes the load-bearing plate 701 to move upward along the inside of the storage barrel 302. When the load-bearing plate 701 moves upward, the load-bearing rod 702 and the connecting rod 705 drive the first heating sleeve 201 to move upward and shorten compared with the second heating sleeve 202.When the swing rod 306 is rotating upward, the swing rod 306 can rotate to the upper side of the hemispherical airbag 305 and drive the hemispherical airbag 305 to compress. When the hemispherical airbag 305 is compressed, the flexible limit strip 307 is driven to expand again, thereby limiting the position of the moved load-bearing plate 701, so that the position of the load-bearing plate 701 after moving is limited within the height range of the through hole. After the load-bearing plate 701 is limited, since the upper surface of the load-bearing plate 701 is in an inclined structure, the solid material on the upper part of the load-bearing plate 701 The nut protein powder can slide off from the lower side of the upper surface of the load-bearing plate 701 and pass through the through hole to act on the sealing plate 303. After the nut protein powder acts on the sealing plate 303, it can pass through the through hole in the reverse direction under the blocking effect of the sealing plate 303 to enter the area below the load-bearing plate 701, and then enter the second heating sleeve 202 and the first heating sleeve 201 from the bottom of the storage barrel 302. The electric heating sheets on the inner walls of the first heating sleeve 201 and the second heating sleeve 202 are used to heat and dry the nut protein powder. ;

[0047] See also Figure 5 In one embodiment, a ring plate 704 is fixedly provided on the load-bearing rod 702, and the side wall of the ring plate 704 is fixedly connected to the inner wall of the storage barrel 302 through a support rod. One end of the second elastic member 703 is connected to the ring plate 704, and the other end is connected to the bottom of the load-bearing plate 701.

[0048] See also Figure 5 In one embodiment, the bottom of the rocker arm 306 is also connected to the outer wall of the storage barrel 302 through a first elastic member 308, and the first elastic member 308 is used to provide elastic tension to the rocker arm 306. A pressure rod 309 is fixedly provided on the side of the sealing plate 303 facing the storage barrel 302, and one end of the pressure rod 309 away from the sealing plate 303 extends from the through opening to the inside of the storage barrel 302.

[0049] When the magnet 804 rotates to the side of the sealing plate 303 and attracts the sealing plate 303 to rotate relative to the outer wall of the storage barrel 302 to open the opening, the sealing plate 303 drives the swing rod 306 to rotate synchronously, and the first elastic member 308 is stretched by force; when the nut protein powder on the upper part of the load-bearing plate 701 completely slides off from the lower end of the upper surface of the load-bearing plate 701, the magnet 804 rotates away from the side of the sealing plate 303, and the first elastic member 308 pulls the swing rod 306 to drive the swing rod 306 and the sealing plate 303 to rotate in the opposite direction, and the sealing plate 303 is re-attached to the outer wall of the storage barrel 302 to continue to seal the opening, and when the swing rod 306 rotates in the opposite direction, the squeezing state of the upper hemispherical airbag 305 is released, and the upper hemispherical airbag 305 expands, thereby attracting the flexible limit strip 307 to shrink. , to release the limiting state of the load-bearing plate 701. At this time, if the load-bearing plate 701 has previously moved upward along the inside of the storage barrel 302, the pressure rod 309 on one side of the sealing plate 303 acts on the load-bearing plate 701 to press the load-bearing plate 701 downward, thereby realizing the downward movement and reset of the load-bearing plate 701. If the load-bearing plate 701 has previously moved downward along the inside of the storage barrel 302, the second elastic member 703 pushes the load-bearing plate 701 to move upward along the inside of the storage barrel 302, thereby realizing the upward movement and reset of the load-bearing plate 701. When the load-bearing plate 701 is reset, the swing rod 306 rotates to the side of the hemispherical airbag 305 below and squeezes the hemispherical airbag 305 below, causing the hemispherical airbag 305 below to collapse, thereby driving the flexible limiting strip 307 to expand, so as to limit the load-bearing plate 701 again.

[0050] See also Figure 5 In one embodiment, the edge of the sealing plate 303 is connected to the rocker rod 306 via a side plate 304. By setting the side plate 304, when the nut protein powder passes through the through opening and acts on the sealing plate 303, the side plate 304 can protect the edge of the sealing plate 303 to prevent the nut protein powder from leaking from the edge of the sealing plate 303.

[0051] In one embodiment, the flexible limiting strip 307 may be a rubber strip or a silicone strip, which is not limited here.

[0052] In one embodiment, the first elastic member 308 and the second elastic member 703 may be springs or metal springs, which are not limited herein.

[0053] See also Figure 1 In one embodiment, a collecting box 60 is disposed below the telescopic heating component 20 . Through the setting of the collecting box 60 , the dry nut protein powder flowing out from the inside of the telescopic heating component 20 can be collected.

[0054] In the embodiment of the present invention, when the nut protein powder is dried, the nut protein powder to be dried can be placed in the discharge area 50 in the material box 30, and the driving component 80 is used to drive the scraper component 40 to rotate. When the scraper component 40 rotates, it drives the nut protein powder in the discharge area 50 to rotate. When the nut protein powder rotates to the discharge port 301, a portion of the nut protein powder enters the storage barrel 302 through the discharge port 301, and then flows downward along the inside of the telescopic heating component 20. The telescopic heating component 20 is used to heat the portion of the nut protein powder to achieve the drying treatment of the portion of the nut protein powder; in the above process, when a portion of the nut protein powder enters the storage barrel 302 through the discharge port 301, if the humidity of the portion of the nut protein powder is relatively high, the weight of the portion of the nut protein powder is relatively heavy, and the load-bearing component 70 is subjected to a relatively large pressure from the portion of the nut protein powder. The load-bearing component 70 drives the telescopic heating component 20 to extend, thereby increasing the flow distance of this part of the nut protein powder inside the telescopic heating component 20, and extending the heating time of this part of the nut protein powder. On the contrary, if the humidity of this part of the nut protein powder is low, the weight of this part of the nut protein powder is light, and the pressure of this part of the nut protein powder on the load-bearing component 70 is small. The load-bearing component 70 drives the telescopic heating component 20 to shorten, thereby reducing the flow distance of this part of the nut protein powder inside the telescopic heating component 20, and shortening the heating time of this part of the nut protein powder. Compared with the prior art, the drying time of the nut protein powder can be controlled according to the humidity of the nut protein powder, effectively avoiding the over-drying of the nut protein powder with low humidity, ensuring the quality of the nut protein powder, and having the advantages of good nut protein powder drying effect and uniform drying.
