Abstract
Description
Technical Field
[0001] This invention relates to the field of food leavening agent mixing technology, specifically to a high-efficiency food leavening agent raw material homogenization and mixing device. Background Technology
[0002] In the food processing industry, food leavening agents, as an important type of food additive, are widely used in the production of various products such as bread, cakes, biscuits, and puffed foods. Their core function is to generate gas during food processing, baking, and cooking, creating a uniform porous structure within the food, thereby improving its texture, fluffiness, and chewiness, and enhancing its overall quality and eating experience. With the increasing scale and sophistication of the food industry, higher demands are placed on the production efficiency, homogenization, and raw material utilization of food leavening agents. The mixing device, as a key piece of equipment in the production process for food leavening agents, directly affects the product quality and production efficiency. Currently, most existing food leavening agent raw material mixing devices use a single rotating stirring rod to achieve raw material mixing. However, food leavening agent raw materials often have a certain degree of viscosity. During the mixing process, some raw materials tend to adhere to the inner wall of the mixing chamber and the surface of the mixing components, or clump together. Existing devices lack an effective scraping structure and cannot remove the adhered raw materials in a timely manner. These adhered raw materials tend to solidify and clump together after long-term accumulation, which not only wastes raw materials but also affects the mixing purity of subsequent batches of raw materials, resulting in unstable quality of the leavening agent product. Summary of the Invention

[0005] Preferably, the transmission assembly includes a gear one located on the outer wall of the gear two and meshing with it. The gear one is rotatably connected to the top cover. The outer periphery of the gear one meshes with the inner side of the rotating gear ring. A fixing ring is fixedly connected to the bottom end of the rotating gear ring, and multiple slots are provided at the bottom end of the fixing ring.
[0006] Preferably, the transmission assembly two includes a gear four located behind the movable plate, a gear three meshing with the rear end of the gear four, a rotating rod fixedly connected to the middle end of the gear three, the top end of the rotating rod rotatably connected to the fixed plate, the bottom end of the rotating rod rotatably connected to the bottom plate, and an inverted bevel gear fixedly connected to the outer wall of the middle end of the rotating rod, the inverted bevel gear being connected to the stirring rod through a bevel gear set.
[0007] Preferably, the bevel gear set includes two meshing bevel gears, one of which is fixedly connected to the outer wall of the stirring rod, and the other bevel gear is driven by a motor, which is mounted on the rear top of the base plate.
[0008] Preferably, a limiting rod is slidably connected to the front end of the movable plate, the top end of the limiting rod is fixedly connected to the fixed plate, and the bottom end of the limiting rod is fixedly connected to the base plate.
[0009] Preferably, one end of the air tube passes through the fixing plate and is connected to the top of the compressed air bag, and the other end of the air tube is fixedly connected to a ring sleeve. The bottom end of the ring sleeve is fixedly connected to the fixing plate, and the ring sleeve is rotatably connected to the stirring rod.
[0010] Preferably, the stirring rod is hollow, and multiple stirring blades are fixedly connected to the outer wall of the bottom end of the stirring rod, and an expansion air bladder is fixedly connected to the outer wall of the bottom end of the stirring rod, and the expansion air bladder is connected to the interior of the stirring rod.
[0011] Preferably, an electric push rod is fixedly connected to each of the four corners of the bottom of the lifting platform, and the bottom of the electric push rod is fixedly connected to the base.
[0012] Preferably, a reciprocating lead screw is fixedly connected to the middle of the fourth gear, the top end of the reciprocating lead screw is rotatably connected to the fixed plate, the bottom end of the reciprocating lead screw is rotatably connected to the base plate, and the moving plate is sleeved on the outer wall of the reciprocating lead screw.
[0013] Preferably, the inverted bevel gear meshes with a bevel gear fixedly connected to the outer wall of the stirring rod.
[0014] Working principle: First, the raw material of the leavening agent is poured into the mixing tank. Then, the mixing tank is placed on the lifting platform, and multiple electric push rods push the lifting platform upward, so that the top of the mixing tank contacts the top cover. Then, the top cover is installed on the top of the mixing tank by the buckle, and multiple insert rods are inserted into the corresponding slots. Then, the motor drives the bevel gear connected to it to rotate. The bevel gear drives the bevel gear on the outer wall of the mixing rod to rotate, which in turn drives the mixing rod to rotate. The rotation of the mixing rod drives the multiple mixing blades on its outer wall to rotate, thus stirring the raw material of the leavening agent in the mixing tank. At the same time, the rotation of the mixing rod drives the cross rod to rotate, which drives the second gear to rotate. The second gear drives the first gear to rotate, which drives the rotating gear ring to rotate. Then, the rotating gear ring drives the first rotating ring through the fixed ring to rotate, which in turn drives the multiple scrapers to rotate. This allows the leavening agent raw material adhering to the inner wall of the mixing tank to be scraped off when stirring the raw material of the leavening agent in the mixing tank, thereby preventing the leavening agent raw material from adhering to the inner wall of the mixing tank. While the bevel gear set rotates, the bevel gear located on the outer wall of the stirring rod also rotates the inverted bevel gear. The rotation of the inverted bevel gear rotates the rotating rod, which in turn rotates the third gear, which in turn rotates the fourth gear, which in turn rotates the reciprocating screw. This causes the moving plate sleeved on its outer wall to move up and down. When the moving plate moves upward, it compresses the air bladder, which then supplies air into the stirring rod through the air pipe. The air then flows into the expansion air bladder, causing it to expand and push away the leavening agent material around the stirring rod. When the moving plate moves downward, the air bladder expands, which in turn causes the expansion air bladder to contract, allowing the leavening agent material to return to the stirring rod. By continuously expanding and contracting the expansion air bladder, the leavening agent material around the stirring rod is continuously pushed, thereby improving the efficiency of mixing the leavening agent material.
[0015] This invention provides a high-efficiency homogenizing and mixing device for food leavening agent raw materials. It has the following beneficial effects: 1. When the stirring rod rotates, the present invention can not only stir the leavening agent raw material, but also rotate the rotating toothed ring. In turn, the rotating toothed ring drives multiple scrapers to rotate, which can scrape off the attached leavening agent raw material in time, avoid the waste of raw material due to long-term adhesion and solidification, and prevent residual raw material from affecting the purity of subsequent stirring. Each batch of leavening agent raw material can fully participate in the stirring, reducing material loss.
[0016] 2. When the stirring rod rotates, the present invention can also compress the air bladder, so that the air bladder injects air into the expansion bladder, causing the expansion bladder to alternately expand to push the raw materials and contract to return to its original position. This breaks the static state of the raw materials around the stirring rod, causing the raw materials to move irregularly, avoiding uneven mixing in certain areas, and accelerating the fusion reaction between the raw materials. Compared with traditional stirring methods, it can achieve a uniform mixing effect in a shorter time. Attached Figure Description
