Description

Technical Field

[0001] This invention relates to the field of food testing technology, specifically to an anti-static low glycemic index powder mixing device. Background Technology

[0002] Low glycemic index powder is a specialized food ingredient designed based on the principles of nutrition and food engineering. Its core feature lies in significantly reducing the content of easily digestible starch in the product and optimizing the composition of carbohydrates through raw material screening and compounding technology. It uses legume powder, grain bran, high-fiber materials, and resistant starch as the main matrix. These components have an extremely low proportion of rapidly digestible starch and a low degree of hydrolysis by small intestinal digestive enzymes, thus preventing a sharp rise in postprandial blood glucose. This powder is mainly used to develop special medical purpose formulation foods for diabetic patients and people with metabolic syndrome, such as low glycemic index noodles, bread, and other products, providing an important material basis for clinical nutritional support and dietary intervention.

[0003] Regarding the technical problems existing in the aforementioned anti-static low glycemic index powder mixing device, a search revealed a patent (CN202223567346.9) for a low glycemic index premixed powder mixing device. This device includes a motor, a mixing drum, a stirring shaft, a support frame, and a hydraulic cylinder. The support frame is connected to the lower part of the outer wall of the mixing drum. A sealing cover is installed on the top of the mixing drum, and the motor is located in the center of the top of the sealing cover. An inlet is opened on one side of the sealing cover. The output shaft of the motor passes through the sealing cover and connects downwards to the stirring shaft. The stirring shaft is connected inside the mixing drum to... Several stirring paddles are connected to a gate-shaped scraper on the stirring shaft above the stirring paddles. The bottom of the mixing tank is funnel-shaped and has a discharge port at the bottom. The premixed powder of this invention is stirred in the mixing tank and scraped against the inner wall of the mixing tank by the scraper, which avoids a large amount of premixed powder sticking to the inner wall of the mixing tank and facilitates subsequent cleaning. A hydraulic cylinder is set at the discharge port. The hydraulic cylinder extends and retracts to drive the sealing plate inside the mixing tank to rise and fall. When the sealing plate rises, the discharge port opens and the premixed powder falls from all sides of the sealing plate to the discharge port, avoiding the premixed powder from clogging at the discharge port.

[0004] In the industrial preparation of low-glycemic index powders, this starch content detection device often requires the precise addition of a certain proportion of low-density, high-bioactivity, or low-glycemic index functional micro-powder raw materials, such as resistant starch, water-soluble dietary fiber, plant protein, and plant extracts, to ensure that the product reaches the designed blood glucose response curve. Low-density micro-powders are prone to generating dust during feeding and mechanical stirring, which not only causes ineffective loss of valuable raw materials and leads to an imbalance in the proportion of key functional components in the product, directly affecting the stability of its glycemic control characteristics, but also poses a dust explosion safety hazard. At the same time, because these raw materials have high surface energy and are prone to static electricity, they generally adhere to the inner wall of the mixing chamber, the stirring shaft, and the blades during the mixing process, forming stubborn scale, resulting in significant material residue after each batch of production, which increases production costs.

[0012] Beneficial effects

[0013] 1. This utility model provides an anti-static low glycemic index powder mixing device. The power unit drives the rotating shaft to rotate, and the support drives the mixing drum to rotate for mixing. When the mixing drum rotates, the powder inside rubs against the conductive ring, and static electricity is transferred to the conductive plate through the conductive ring. When the mixing drum rotates, the conductive plate contacts the contact head, and the static electricity in the contact head moves to the static discharger through the extrusion plate and spring for dissipation. During the mixing process, the synergistic effect of the conductive ring and the contact head achieves real-time static dissipation, completely eliminating the agglomeration of lightweight functional powders caused by static electricity. This significantly improves the dispersion uniformity of key components such as resistant starch, dietary fiber, and plant extracts, ensuring that each batch of product maintains stable low glycemic index characteristics. The timely elimination of static electricity avoids powder adhesion residue in the equipment, reducing the loss of valuable raw materials and ensuring the accuracy of the formula ratio.

[0014] 2. This utility model provides an anti-static low glycemic index powder mixing device. During the mixing process, the mixing drum rotates, and the rotating rod contacts both ends of the mixing drum through the movable head. The movable head drives the rotating rod to rotate inside the mixing drum. During the rotation of the rotating rod, the stirring frame rotates, and the stirring blades mix the powder. When the powder is thrown up, the buffer plate inside the stirring tube covers the thrown powder to prevent it from being thrown up in the mixing drum. During the operation of the mixing drum, when the powder is thrown up due to the rotation, the buffer plate can intervene in time to effectively block the movement trajectory of the dust, change the upward path of the dust, weaken its kinetic energy after contacting the buffer plate, and finally fall back to the mixing area under the action of gravity. This significantly reduces the dust emission of lightweight functional components, not only reducing raw material loss, but also effectively avoiding cross-contamination, providing a good process guarantee for the production of low glycemic index powder.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0022] Please see Figure 1-5 An antistatic low-glycemic powder mixing device includes a power box 1, a bracket 101 fixedly connected to the bottom of the power box 1, a rotating shaft 102 fixedly connected to the output end of the power box 1, a rotating frame 103 movably connected to the outer surface of the rotating shaft 102, a mixing tank 2 movably connected inside the rotating frame 103, a feed hopper 201 fixedly connected to the top of the mixing tank 2, a discharge hopper 202 fixedly connected to the bottom of the mixing tank 2, a movable rail 203 fixedly connected to the outer surface of the mixing tank 2, an insulating ring 204 fixedly connected inside the movable rail 203, a conductive plate 205 fixedly connected to the outer surface of the insulating ring 204, a conductive ring 206 movably connected to the inner wall of the mixing tank 2, an electrostatic release device 3 fixedly installed on the outer surface of the power box 1, an outer tube 304 fixedly connected to the outer surface of the electrostatic release device 3, a spring 301 movably connected inside the outer tube 304, an extrusion plate 302 fixedly connected to the outer surface of the spring 301, and a contact head 303 fixedly connected to the outer surface of the extrusion plate 302.

[0023] The power box 1 outputs a drive shaft 102 to rotate, and the bracket 101 drives the mixing tank 2 to rotate for mixing. When the mixing tank 2 rotates, the powder inside comes into contact with the conductive ring 206 through friction. Static electricity is transferred through the conductive ring 206 to the conductive plate 205. When the mixing tank 2 rotates, the conductive plate 205 comes into contact with the contact head 303. The static electricity in the contact head 303 is then moved to the static electricity release device 3 through the extrusion plate 302 and the spring 301 for static electricity dissipation. During the mixing process, the conductive ring 206 and the contact head 303 work together to achieve real-time static electricity dissipation, completely eliminating the agglomeration of lightweight functional powder caused by static electricity. This significantly improves the dispersion uniformity of key components such as resistant starch and dietary fiber, ensuring that each batch of product maintains stable low glycemic properties. The timely elimination of static electricity avoids the adhesion and residue of powder in the equipment, reducing the loss of valuable raw materials and ensuring the accuracy of the formula ratio.

[0024] In this embodiment, the interior of the movable rail 203 is recessed downwards, the insulating ring 204 is rotatably disposed inside the movable rail 203, the conductive plate 205 is located around the surface of the insulating ring 204, the back of the conductive plate 205 is embedded inside the insulating ring 204 and abuts against the conductive ring 206, the extrusion plate 302 is disposed from front to back inside the contact head 303, the contact head 303 passes through the front end of the contact head 303 and abuts against the conductive plate 205.

[0026] A rotating rod 4 is movably connected inside the mixing tank 2. A stirring tube 401 is fixedly connected to both sides of the rotating rod 4. A buffer plate 402 is fixedly connected inside the stirring tube 401. An agitator 403 is fixedly connected to the top and bottom of the rotating rod 4. An agitator plate 404 is fixedly connected to the outer surface of the agitator 403. A movable head 405 is fixedly connected to the top of the agitator 403.

[0027] During the mixing process, as the mixing drum 2 rotates, the rotating rod 4 contacts both ends of the mixing drum 2 through the movable head 405. The movable head 405 drives the rotating rod 4 to rotate inside the mixing drum 2. During the movement of the rotating rod 4, the stirring frame 403 rotates, and the stirring blade 404 mixes the powder. When the powder is thrown up, the buffer plate 402 inside the stirring tube 401 covers the thrown powder, preventing the powder from being thrown up inside the mixing drum 2. During the operation of the mixing drum, when the powder is thrown up due to the rotation, the buffer plate 402 can intervene in time to effectively block the movement trajectory of the dust, change the upward path of the dust, weaken its kinetic energy after contacting the buffer plate, and finally fall back to the mixing area under the action of gravity. This significantly reduces the dust emission of lightweight functional components, not only reducing raw material loss, but also effectively avoiding cross-contamination, providing a good process guarantee for the production of low glycemic index powder.

[0028] In this embodiment, one end of the movable head 405 is a conical structure, the rotating rod 4 is rotated 360 degrees inside the mixing tank 2 through the movable head 405, the stirring tube 401 is a semi-circular arc structure, the buffer plate 402 has uniformly distributed holes inside, the stirring frame 403 is a cross structure, and the stirring plate 404 is perpendicular to the stirring frame 403.
