Description

Technical Field

[0001] This utility model relates to the field of jelly processing technology, specifically a heating and stirring machine that facilitates internal cleaning. Background Technology

[0002] The processing of jelly mainly includes steps such as ingredient selection, soaking, cooking, solidification, and cutting. First, high-quality starch raw materials (such as mung bean starch or pea starch) are soaked in water until fully absorbed, then ground into a slurry. Next, the starch slurry is heated to a boil, stirring constantly until it becomes viscous and forms a gelatinous consistency. At this point, the cooked starch solution is poured into molds to cool. After a period of solidification, it forms transparent, elastic jelly blocks. Finally, the solidified jelly is removed, cut into thin slices or strips, and then various seasonings and ingredients can be added to create uniquely flavored jelly dishes. The entire processing is simple, but requires careful selection of raw materials and precise control of heat to ensure the final product has a delicate and smooth texture.

[0003] In the processing of jelly, the stirring device is crucial for ensuring uniform heating of the starch slurry and preventing clumping. However, the stirring device comes into frequent contact with the starch slurry during use. Over time, starch components in the slurry may adhere to the inner walls of the equipment, especially during stirring, when the viscous liquid tends to adhere to the surface of the stirrer and container. With repeated use, these residues gradually accumulate, easily forming stains that are difficult to clean. If not cleaned promptly and effectively, the residual starch and other impurities will not only affect the lifespan of the equipment but may also impact the quality of the product in subsequent processing. First, accumulated starch residue may lead to poor stirring performance, affecting the uniformity and quality of the starch slurry. Second, long-term uncleaned dirt can become a breeding ground for bacteria and microorganisms, increasing food safety risks and affecting the hygiene standards of the jelly.

[0004] To address the aforementioned issues, we have made improvements by proposing a heated mixer that facilitates internal cleaning. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heating mixer that is easy to clean internally, including a base plate, a mixing cylinder arranged above the base plate, a cylinder cover snapped onto the top of the mixing cylinder, a fixed box fixedly connected to the back side of the top of the base plate, a screw rod movably connected to the inner cavity of the fixed box through a bearing, a threaded sleeve connected to the surface of the screw rod, connecting plates fixedly connected to both sides of the threaded sleeve, a transmission rod fixedly connected to the top of the connecting plate, and the front end of the transmission rod fixedly connected to the back side of the cylinder cover.

[0006] Preferably, the left and right sides of the inner wall of the fixed box are provided with sliding grooves, the outer side of the connecting plate is slidably connected to the inner cavity of the sliding groove, and the left and right sides of the top of the fixed box are provided with guide grooves.

[0007] Preferably, a servo motor for driving the screw rotation is fixedly connected to the top of the fixed box, and the output end of the servo motor is fixedly connected to the top of the screw.

[0008] Preferably, a stepper motor is fixedly connected to the top of the cylinder cover, a stirring rod is fixedly connected to the output end of the stepper motor, a plurality of stirring blades are fixedly connected to the surface of the stirring rod, heat-conducting plates are embedded on both the left and right sides of the bottom of the inner wall of the stirring cylinder, and a heating plate is embedded on the inner surface of the stirring cylinder and at the bottom of the heat-conducting plates.

[0009] Preferably, a retaining seat is fixedly connected to the bottom of both sides of the stirring rod, a connecting rod is engaged in the inner cavity of the retaining seat, and a cleaning scraper is fixedly connected to the outer side of the connecting rod, with the outer side of the cleaning scraper contacting the inner wall of the stirring cylinder.

[0010] Preferably, a discharge pipe is connected to the middle of the bottom of the mixing drum, a feed pipe is connected to the left side of the top of the drum cover, a fixing ring is fixedly connected to the outer side of the mixing drum, and support frames are fixedly connected to the left and right sides of the bottom of the fixing ring, with the bottom of the support frame fixedly connected to the top of the base plate.

[0011] Compared with the prior art, this utility model provides a heating mixer that is easy to clean internally, and has the following beneficial effects:

[0012] 1. This heating mixer, which facilitates internal cleaning, uses the output of a servo motor to drive a screw to rotate. The screw, through its thread, moves a threaded sleeve upward, which in turn moves a connecting plate upward. The connecting plate then moves a transmission rod upward, which in turn moves the cylinder cover upward, pushing the stirring rod and stirring blades out of the inner cavity of the mixing drum. This facilitates subsequent cleaning of the stirring blades and the inner cavity of the mixing drum, improving the cleaning effect.

[0013] 2. This heating mixer, which facilitates internal cleaning, effectively improves the stability of the connecting plate and screw sleeve during vertical movement by setting a sliding groove. The output end of the stepper motor drives the stirring rod to rotate, which in turn drives the stirring blades to rotate, thus stirring the material. During the stirring process, the stirring rod drives the connecting rod to rotate, which in turn drives the cleaning scraper to rotate along the inner wall of the mixing drum. This allows for cleaning of the inner wall of the mixing drum during the stirring process, preventing material from sticking to the wall. The setting of a retaining seat makes it easy to disassemble the cleaning scraper for cleaning or replacement. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The heating mixer, designed for easy internal cleaning, includes a base plate 1, a mixing drum 2 mounted on top of the base plate 1, a drum cover 3 snapped onto the top of the mixing drum 2, a fixed box 4 fixedly connected to the back side of the top of the base plate 1, a screw 23 movably connected to the inner cavity of the fixed box 4 via bearings, a threaded sleeve 16 connected to the surface of the screw 23, connecting plates 17 fixedly connected to both sides of the threaded sleeve 16, a transmission rod 5 fixedly connected to the top of the connecting plate 17, the front end of the transmission rod 5 fixedly connected to the back side of the drum cover 3, sliding grooves 19 opened on both sides of the inner wall of the fixed box 4, the outer side of the connecting plate 17 slidably connected to the inner cavity of the sliding groove 19, guide grooves 18 opened on both sides of the top of the fixed box 4, a servo motor 22 for driving the screw 23 to rotate fixedly connected to the top of the fixed box 4, and the output end of the servo motor 22 fixedly connected to the top of the screw 23.

[0022] Through the above technical solution, the output end of the servo motor 22 drives the screw 23 to rotate. The screw 23 uses the thread to drive the screw sleeve 16 to move upward. The screw sleeve 16 drives the connecting plate 17 to move upward. The connecting plate 17 drives the transmission rod 5 to move upward. The transmission rod 5 drives the cylinder cover 3 to move upward, pushing the stirring rod 9 and the stirring blade 10 out of the inner cavity of the stirring cylinder 2. This facilitates subsequent cleaning of the stirring blade 10 and the inner cavity of the stirring cylinder 2, improving the cleaning effect. By setting the sliding groove 19, the stability of the connecting plate 17 and the screw sleeve 16 during the up and down movement can be effectively improved.

[0023] Specifically, a stepper motor 8 is fixedly connected to the top of the cylinder cover 3, a stirring rod 9 is fixedly connected to the output end of the stepper motor 8, multiple stirring blades 10 are fixedly connected to the surface of the stirring rod 9, heat-conducting plates 14 are embedded on both the left and right sides of the bottom of the inner wall of the stirring cylinder 2, a heating plate 15 is embedded on the inner surface of the stirring cylinder 2 and at the bottom of the heat-conducting plates 14, a retaining seat 11 is fixedly connected to the bottom of both the left and right sides of the stirring rod 9, a connecting rod 13 is engaged in the inner cavity of the retaining seat 11, a cleaning scraper 12 is fixedly connected to the outer side of the connecting rod 13, the outer side of the cleaning scraper 12 contacts the inner wall of the stirring cylinder 2, a discharge pipe 7 is connected to the middle of the bottom of the stirring cylinder 2, a feed pipe 6 is connected to the left side of the top of the cylinder cover 3, a fixing ring 21 is fixedly connected to the outer side of the stirring cylinder 2, a support frame 20 is fixedly connected to both the left and right sides of the bottom of the fixing ring 21, and the bottom of the support frame 20 is fixedly connected to the top of the base plate 1.

[0024] Through the above technical solution, the output end of the stepper motor 8 drives the stirring rod 9 to rotate, and the stirring rod 9 drives the stirring blade 10 to rotate, thus stirring the material. During the stirring process, the stirring rod 9 drives the connecting rod 13 to rotate, and the connecting rod 13 drives the cleaning scraper 12 to rotate along the inner wall of the stirring drum 2. This can clean the inner wall of the stirring drum 2 during the stirring process and prevent the material from sticking to the wall. By setting the retainer 11, the cleaning scraper 12 can be easily disassembled for cleaning or replacement.

[0025] In use, the output of the stepper motor 8 first drives the stirring rod 9 to rotate, which in turn drives the stirring blades 10 to rotate, thus stirring the material. During the stirring process, the stirring rod 9 drives the connecting rod 13 to rotate, which in turn drives the cleaning scraper 12 to rotate along the inner wall of the mixing drum 2. This cleans the inner wall of the mixing drum 2 during the stirring process, preventing material from sticking to the wall. After use, the output of the servo motor 22 drives the screw 23 to rotate. The screw 23 uses its thread to drive the screw sleeve 16 to move upward, which in turn drives the connecting plate 17 to move upward. The connecting plate 17 drives the transmission rod 5 to move upward, which in turn drives the drum cover 3 to move upward, pushing the stirring rod 9 and the stirring blades 10 out of the inner cavity of the mixing drum 2. This facilitates subsequent cleaning of the stirring blades 10 and the inner cavity of the mixing drum 2, improving the cleaning effect. (The above is the working process of the entire device.
