Description

Technical Field

[0001] This utility model relates to the field of rice bran drying technology, and more specifically to a drying device for rice bran protein production. Background Technology

[0002] Rice bran protein, as a high-quality plant protein resource, has broad application prospects in the food, health product, and pharmaceutical fields due to its rich content of essential amino acids, low allergenicity, and good functional properties. However, rice bran protein powder is prone to clumping during the drying process due to material deposition, localized overheating, or moisture retention, resulting in poor product uniformity, loss of active ingredients, and low production efficiency, becoming a key technical bottleneck restricting its large-scale production.

[0003] Secondly, the material is in a static, piled-up state within the tray dryer, allowing hot air to pass only through the surface, making it difficult for internal moisture to migrate. In the later stages of drying, the surface material is prone to denaturation due to overheating, while residual moisture remains inside, resulting in a "dry outside, wet inside" clumping phenomenon. Traditional drum dryers use drum rotation to tumble the material, but this tumbling method relies solely on gravity, failing to effectively break up the material deposits at the bottom of the drum. This application is proposed to address the aforementioned technical problems. Utility Model Content

Each of the dispersing components includes a gear shaft rotatably connected to the lower end of the inclined plate. Each gear shaft is meshed with a bevel gear for transmission.

Detailed Implementation

[0020] See Figures 1 to 6 The diagram shows an embodiment of the present invention that breaks the sediment layer of rice bran protein powder to avoid clumping caused by local overheating or moisture retention.

[0021] A drying device for rice bran protein production includes a cylindrical body 101 with supporting legs welded to its bottom. A heating element is installed on the cylindrical body 101. A discharge port 102 is opened on the bottom surface of the cylindrical body 101. A bottom plate 104 is interference-fitted into the discharge port 102. A rotating shaft 202 is rotatably connected to the core of the cylindrical body 101. A motor 201 for driving the rotating shaft 202 is fixed to the bottom surface of the cylindrical body 101. The motor 201 is fixed to the cylindrical body 101 by a motor frame and bolts. The rotating shaft 202 is connected to the output shaft of the motor 201 by a coupling. Multiple inclined plates 301 that are in contact with the bottom surface of the cylindrical body 101 are fixed around the rotating shaft 202. A disintegrating component is installed at the lower end of each inclined plate 301.

[0022] The cylinder 101 is covered by a cover plate 106.

[0023] Rice bran protein powder is added into cylinder 101, and cover plate 106 is placed on top of cylinder 101. Since water activity is a crucial factor affecting food stability, low water activity can inhibit the growth and reproduction of microorganisms, reduce enzymatic reactions, and thus slow down the spoilage process of rice bran protein. Therefore, by controlling the power supply to the heating element, the rice bran protein in cylinder 101 is heated and dried, thereby reducing the moisture content and lowering the possibility of oxidation, hydrolysis, and other chemical changes in the rice bran protein, thus preserving its nutritional value and functional properties.

[0024] Rice bran protein powder tends to form a sediment layer at the bottom of the drying drum due to gravity, leading to localized overheating or moisture retention. Therefore, the motor 201 is started to drive the rotating shaft 202 to rotate. The rotating shaft 202 drives multiple inclined plates 301 to rotate synchronously. During the rotation of the multiple inclined plates 301, the rice bran protein powder at the bottom of the drum 101 is scooped up and then thrown down from above the inclined plates 301, forming a continuous material flow, effectively breaking up the sediment layer and preventing clumping.

[0025] The inclined angle design of the slanted plate 301 creates a dispersion effect on the rice bran protein powder during the falling process, reducing particle adhesion and ensuring that each particle of protein powder fully contacts the hot air, thus improving drying uniformity. Furthermore, the slanted plate 301 scoops the material from the bottom, significantly increasing the contact area between the protein powder and the hot air during the falling process, accelerating moisture evaporation. The rotational motion of the slanted plate 301 continuously mixes the material within the drum, preventing localized overheating that could lead to protein denaturation or nutrient loss.

[0026] Based on this, the inclined plate 301 scoops up and throws the bottom material, forming a preliminary vertical flow, while the dispersing component further disperses the thrown material from the horizontal direction. This "vertical + horizontal" composite motion mode completely breaks up the deposit layer of rice bran protein powder in the cylinder 101, avoiding clumping caused by local overheating or moisture retention.

[0027] See Figure 3 , 4 Figures 10 and 10 show schematic diagrams of an embodiment of material discharge according to the present invention;

[0028] The bottom surface of the base plate 104 is integrally formed with protruding ridges that facilitate manual removal of the base plate 104.

[0029] The cylinder 101 has grooves 103 on both sides of the discharge port 102. Both ends of the bottom plate 104 are integrally formed with protrusions 105 that are slidably connected in the grooves 103. The cooperation between the grooves 103 and the protrusions 105 limits the bottom plate 104 to prevent it from falling downwards and causing the rice bran protein to be discharged from the discharge port 102.

[0030] When it is necessary to discharge the dried rice bran protein, place the box below the discharge port 102, manually pull the protrusion outward to remove the bottom plate 104 from the discharge port 102 and discharge the dried protein powder into the box for collection.

[0031] The upper end of the rotating shaft 202 is rotatably connected to the cover plate 106. The cover plate 106 can support and position the upper end of the rotating shaft 202, making the rotating shaft 202 more stable during rotation and preventing shaking. Secondly, the cover plate 106 also prevents heat loss inside the cylinder 101.

[0032] See Figure 7 and 8 The diagram shows an embodiment of further dispersing rice bran protein powder according to the present invention.

[0033] The core of the cylinder 101 is welded and fixedly connected to a bushing 204 that is sleeved on the rotating shaft 202. A bevel gear 205 is fixedly connected to the bushing 204 by screws. Each of the disintegrating components includes a gear shaft 304 that is rotatably connected to the lower end of the inclined plate 301. Each gear shaft 304 is meshed and connected to the bevel gear 205. A stirring blade 305 is fixedly connected to each gear shaft 304.

[0034] The rotating shaft 202 drives the inclined plate 301 to rotate, which in turn drives the gear shaft 304 to rotate synchronously. The gear shaft 304 is connected to the bevel gear 205 through meshing transmission, which in turn drives the stirring blade 305 to rotate. If the material thrown from the inclined plate 301 forms clumps, the vertically falling clumps will land on the horizontally rotating stirring blade 305, which can further break them down into finer particles, further preventing the rice bran protein powder from clumping and ensuring that each particle of protein powder can independently contact the hot air.

[0035] Multiple stirring rods 203 are fixedly attached to the rotating shaft 202 to stir the rice bran protein powder in the middle and upper layers. The stirring rods 203 can also be replaced with stirring plates, which have a larger stirring area and higher efficiency.

[0036] The lower end of each stirring rod 203 extends to the corresponding inclined plate 301. If the material falling from the inclined plate 301 forms clumps, the clumps will come into contact with the multiple stirring rods 203 when they fall from the upper end of the inclined plate 301. The multiple stirring rods 203 will first disperse the large clumps into smaller clumps, and the multiple rotating bevel gears 205 will further break up the smaller clumps, thus improving the crushing effect of rice bran protein powder.

[0037] See Figure 4 A schematic diagram of an embodiment of heating according to the present invention is shown;

[0038] The heating element includes multiple heating plates 107 that are fixedly attached to the outer wall of the cylinder 101. The heating element also includes a heating ring 108 fixedly attached to the bottom surface of the cylinder 101. The heating plates 107 and the heating ring 108 are activated to uniformly heat the rice bran protein powder inside the cylinder 101.

[0039] Furthermore, each of the inclined plates 301 has a side plate 303 fixedly attached to both ends. The two side plates 303 guide the protein powder scooped up by the inclined plates 301, so that the protein powder flows smoothly through the inclined plates 301 and then falls off.

[0040] Multiple partitions 302 are fixed to each of the inclined plates 301. When the protein powder passes through the partitions 302, it is subjected to the shearing force of the partitions 302, which further breaks large particles into smaller particles or large clumps into smaller clumps.
