Description

Technical Field

[0001] The present invention belongs to the technical field of fine processing of grains, and particularly relates to a fine processing device for grains. Background Art

[0002] Fine processing of grains refers to removing the husk, germ, and part of the bran from raw grains (such as wheat, rice, corn, etc.) through a series of physical or chemical treatments to process them into finer finished products (such as polished rice, refined flour, etc.). Although this process improves the taste and shelf life, it may also be accompanied by nutrient loss.

[0003] The authorized publication number "CN113210034A" discloses "a rice cleaning and processing device, including a barnyard grass removal system, a primary cleaning sieve system, a secondary screening system, and a hulling system arranged in sequence; a crawler system is arranged between the primary cleaning sieve system and the secondary screening system, and between the secondary screening system and the hulling system; the working logic of the barnyard grass removal system, the primary cleaning sieve system, the crawler system, and the secondary screening system of the present invention is more efficient. On the one hand, the removal operation line of rod-shaped impurities - metal impurities - light impurities - heavy impurities - non-full grains is adopted to ensure the high efficiency and convenience of screening. On the other hand, the working scheme of limiting batches and limiting flow makes it possible to carry out refined operations and guarantees the high quality of the final product."

[0004] Although fine processing of grains improves product diversity and economic value, there are also significant disadvantages and deficiencies, mainly concentrated in aspects such as nutrient loss, health risks, resource waste, and environmental impact, among which:

[0005] 1. By-products such as bran, rice bran, and germ generated during processing are usually used as low-value feeds or discarded, and only a small amount is extracted for high-value components (such as rice bran oil), resulting in resource waste. For example, about 150 million tons of rice bran are not effectively utilized globally every year;

[0006] 2. In grain processing, links such as milling, drying, and puffing rely on a large amount of electric energy and heat energy, resulting in high carbon emissions, and often one machine can only perform one type of processing. For example, a milling device can only perform milling, with poor energy utilization efficiency and high costs. Summary of the Invention

Since the refined grains are smaller in size, they fall to the lower end of the processing shell and are collected. Then, the pushing mechanism pushes the rice bran deposited above the filter plate to the left into the reflux shell. The external shell arranged in the reflux shell heats the rice bran and returns it to the filter plate through the reflux pipe. While the pushing mechanism is moving, it will synchronously drive the switching mechanism to switch the processing mechanism to a stepped pressing assembly, and then the stepped pressing assembly presses the rice bran for oil extraction again. Then, the pushing mechanism is moved to the right again to scrape the rice bran on the upper side of the filter plate to the right and transfer it to the reaction shell. The rice bran is reacted in the reaction shell through enzymatic hydrolysis or alkali to generate dietary fiber.

[0028] 2. Through the first funnel, grains can be conveniently added to the processing shell quickly, improving the adding speed and efficiency of grains. Through the second funnel, the processed substances can be quickly concentrated and discharged, improving the convenience of adding and discharging of the present device.

Through the external connecting pipe and the connecting flange, the reaction shell can be conveniently connected to external devices, improving the external connection convenience of the device.

The second moving groove 113, the rotating groove 111, and the first moving groove 110 are all opened at one end of the processing shell 1. The second rack 114 and the first rack 109 are respectively slidably connected to the second moving groove 113 and the first moving groove 110. The gear 112 is rotatably connected to the rotating groove 111 through a rotating rod. The second rack 114 is fixedly connected to the separation shell 301. Both ends of the docking rod 106 are fixedly connected to the first rack 109 and the lead screw nut 108 respectively;

[0051] One end of the processing shell 1 is fixedly connected with a reflux shell 2. One end of the reflux shell 2 is fixedly connected with an external shell 201. A plurality of electric fans 205 are arranged in the external shell 201. A reflux pipe 202 is fixedly connected between the reflux shell 2 and the processing shell 1, and the reflux shell 2 and the processing shell 1 are communicated through the reflux pipe 202.

[0052] In a specific embodiment of the present invention, when it is necessary to process grains, the grains are added into the separation shell 301 through the addition slot 313. When the grains pass through the separation roller 312, the rotation of the output shaft of the second motor 321 fixedly connected to one end of the mounting frame 320 drives the rotation of one of the rotating shafts. Then, through the cooperation of the tooth chain 319 and multiple sprockets 318, multiple separation rollers 312 are driven to rotate, and the grains are roller-milled and separated into refined grains and rice bran. Then, the two substances are separated by the filter plate 115. The refined grains are discharged through the opening at the lower end of the processing shell 1, while the rice bran remains on the upper side of the filter plate 115. After that, the first motor 107 is started to drive the lead screw 105 to rotate by its output shaft. The mounting plate 104 serves as the support plate for the first motor 107 and the lead screw 105. After the lead screw 105 rotates, the lead screw nut 108 threadedly connected thereto moves to the left. At the same time, the driving rod 116, the connecting column 117, and the push-pull plate 118 are driven to move to the left synchronously through the push slot. While the push-pull plate 118 moves to the left, it moves through the opening slots provided at both ends of the processing shell 1, and the rice bran accumulated on the upper end of the filter plate 115 is pushed into the reflux shell 2. Subsequently, the rice bran is heated by multiple external shells 201 provided in the external shell 201 so that its moisture content is between 8% and 12%, and it is retransmitted to the upper side of the filter plate 115 through the reflux pipe 202. While the lead screw nut 108 gradually moves to the left, it drives the docking rod 106 and the first rack 109 to move to the left, causing the first rack 109 to slide in the first moving slot 110 and engage with the gear 112 to rotate in the rotating slot 111. The rotating slot 111 also drives the second rack 114 engaged therewith to move to the right in the second moving slot 113, driving the separation shell 301 to move to the right, gradually moving away from the central position of the processing shell 1. When the separation shell 301 moves away, the oil extraction shell 302 is guided towards the central position of the processing shell 1 by multiple connecting rods 322. When the lead screw nut 108 moves to the maximum distance, the first motor 107 stops working. At the same time, the separation shell 301 moves to the upper side of the reaction shell 102, and the oil extraction shell 302 is at the central position of the processing shell 1. Subsequently, the electric guide rail 307 is started to drive the electric slider 306 slidably connected to its circumferential surface to move to the right, driving the abutting rod 304 to abut against the stepped block 309. Since the shape of the stepped block 309 is stepped, during the continuous abutment of the abutting rod 304 and the stepped block 309, the stepped block 309 will be continuously pushed downward. At the same time, the pressing plate 308 is moved towards the filter plate 115, and the rice bran is subjected to oil extraction treatment. At the same time, the electric guide rail 307 can also control the abutting rod 304 to move to the left. Through the resilience of the spring 310, the stepped block 309 and the pressing plate 308 can be pulled upward again, enabling the pressing plate 308 to move up and down repeatedly, continuously extracting oil from the rice bran. After the rice bran is completely extracted, the rice bran oil is discharged again through the opening at the lower end of the processing shell 1, and the rice bran residue will be on the upper side of the filter plate 115.At this time, it should be noted that the push-pull plate 118 is located on the left side of the filter plate 115. Then, reverse-start the first motor 107 so that the rotation direction of its output shaft is reversed, and at the same time, the movement of various components affected by it also moves in the reverse direction. At this time, the push-pull plate 118 located on the left side of the filter plate 115 will move to the right to scrape the rice bran residue on the filter plate 115 to the right, so that the rice bran residue falls to the lower end of the reaction shell 102 and is partitioned by the middle partition plate 119. A certain amount of dietary fiber is produced by reacting the rice bran residue with the reaction enzymes or alkalis inside the reaction shell 102, which facilitates subsequent separation and utilization. Through the above design, the device can make more thorough use of grains, and the power consumption required by the device is lower than that of traditional devices. That is, while reducing power consumption, the utilization rate of grain processing is improved;

[0053] Preferably, the process of reacting rice bran with specific enzymes is as follows:

[0054] 1. React rice bran with α-amylase at 50-60°C and pH 6-7 for 1-2 hours to decompose starch into glucose;

[0055] 2. Add protease and treat at 40-50°C and pH 7-8 for 2 hours to degrade protein into amino acids;

[0056] 3. Use cellulase to partially hydrolyze cellulose at 50°C and pH 4.5-5.5 to generate soluble dietary fiber such as oligosaccharides;

[0057] Finally, it is discharged by the device and processed into solid dietary fiber through drying treatment, etc. It should be noted that: the reaction methods and processes selected by this device are only one of the existing methods.

[0058] For details, please refer to Figures 1-7 , one end of the reaction shell 102 is fixedly connected with an external connection pipe 103, and one end of the external connection pipe 103 is fixedly connected with a connection flange.

[0059] In this embodiment: through the external connection pipe 103, various substances listed above can be gradually added into the reaction shell 102 in batches, and the products obtained by the reaction of the rice bran in the reaction shell 102 can be discharged and collected. Through the connection flange, the connection convenience between the external connection pipe 103 and the external device can be improved.

A stable groove 314 is opened at one end of the processing shell 1, and a stable block 316 is fixedly connected to one end of the separation shell 301.

[0063] In this embodiment, when the lead screw nut 108 moves, it can move on the circumferential surface of the horizontal rod 120 through the horizontal hole, improving the horizontal movement stability of the lead screw nut 108. When the separation shell 301 moves, it will drive the stable block 316 to move in the stable groove 314, improving the horizontal movement stability of the separation shell 301. One inner wall of one side of the stable groove 314 is fixedly connected to a stable rod 315, and a round hole is opened in the middle of the stable block 316. Through the round hole, it can slide on the circumferential surface of the stable rod 315, improving the matching sliding stability of the stable block 316 and the stable groove 314. The limiting plate 317 fixedly connected to one end of the stable rod 315 can prevent damage caused by excessive sliding of the stable block 316.

[0064] Preferably, two telescopic rods 311 are fixedly connected to the upper inner wall of the oil extraction shell 302. The telescopic rods 311 can prevent the spring 310 from bending and deforming. One end of the electric guide rail 307 is fixedly connected to an anti - detachment block 305. The anti - detachment block 305 can prevent the electric slider 306 from moving excessively. One end of the processing shell 1 is fixedly connected to a protective shell 303.
