Description

Technical Field

[0001] This utility model relates to the field of confectionery processing technology, specifically to a sugar boiling device that is easy to clean. Background Technology

[0002] In the confectionery industry, sugar boiling equipment is an indispensable core piece of equipment. Its core function is to concentrate the sugar solution to a high concentration of over 97% by heating and evaporating the water in the syrup, thereby giving the candy its specific hardness and structural characteristics. Currently, the industry generally uses pot-type sugar boiling pots or barrel-type sugar boiling tanks as the mainstream equipment. After a batch of syrup is boiled, a solidified sugar film inevitably adheres to the inner wall of the pot and the surface of the agitator, requiring thorough cleaning to ensure the quality of subsequent production.

[0003] Traditional cleaning methods rely primarily on the water-soluble properties of sugars: first, water is poured into a pot to a height exceeding the sugar film; then, a stirrer is activated to dissolve the sugar film by flushing it out with water. This process of adding water, stirring, and draining water is typically repeated 2-3 times to achieve the desired cleanliness. While this immersion cleaning method effectively removes residues, it has significant drawbacks—a single cleaning cycle consumes 200-300 liters of water, and the water filling and draining process takes over 30 minutes, resulting in water waste and increased wastewater treatment costs.

[0004] To reduce cleaning costs, some factories use handheld high-pressure spray guns for localized rinsing. While this method reduces water consumption, operators must work at close range in a high-temperature environment, which is not only inconvenient but also poses a risk of burns. Furthermore, the spray guns cannot reach hidden areas such as the joints between the stirring shaft and the pot, creating blind spots that can lead to microbial growth. More seriously, the high-pressure water jets impacting the sugar film can cause sugary wastewater to splash, polluting the surrounding environment and increasing the risk of slips and falls for cleaning personnel.

[0005] Therefore, a sugar-boiling device that is easy to clean is designed, which can achieve the effects of using less water, being clean, and being easy to operate. Utility Model Content

[0006] The purpose of this invention is to provide a sugar-boiling device that is easy to clean, in order to solve the problems described in the background art.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A sugar-cooking device that is easy to clean includes two support bases and a pot body disposed between the two support bases. The inner wall of the pot body is hemispherical, and a heating jacket is provided between the inner and outer walls of the pot body. An air inlet pipe and an air outlet pipe communicating with the heating jacket are also provided on the outer wall of the pot body. Rotary shafts are symmetrically fixed in the upper middle part of the outer wall of the pot body. The rotating shafts are rotatably inserted in the support bases. One side of the rotating shaft extends outward from the support base and is fixedly fitted with a driven wheel. A drive mechanism for driving the driven wheel to rotate is also provided on the support bases. A mounting rod is fixedly connected between the two support bases. The mounting rod is located above the pot body and a gearbox is fixedly mounted on the mounting rod. The input shaft of the gearbox also drives a stirring motor. The output shaft of the gearbox... An axial extension extends downward and is connected to a stirring shaft. The central axis of the stirring shaft coincides with the central axis of the inner wall of the pot. An arc-shaped stirring scraper is provided at the bottom of the stirring shaft. The bottom of the stirring scraper slides against the inner wall of the pot. A crossbar is also fixed on the mounting rod, and a duckbill nozzle is installed on the crossbar. The duckbill nozzle is located above the pot and is used to spray a flat fan-shaped water mist. The flat fan-shaped water mist sprayed by the duckbill nozzle completely covers the stirring shaft within the pot. Two anti-splash half-covers are also provided above the pot. The two anti-splash half-covers are detachably connected to form a ring-shaped anti-splash cover. The anti-splash cover is detachably placed at the top of the pot to cover the edge of the opening at the top of the pot.

[0009] When using the above method, steam is introduced into the heating jacket of the pot body through the air inlet and exhaust pipes to heat the inner wall of the pot. Sugar is added to the pot body, the stirring motor drives the gearbox, the gearbox drives the stirring shaft to rotate, and the stirring shaft drives the stirring scraper to rotate to stir the syrup. By setting the arc-shaped stirring scraper and making its bottom slide against the inner wall of the pot body, the syrup on the inner wall of the pot body is continuously scraped, preventing the syrup from caramelizing on the inner wall of the pot body. After the sugar boiling is completed, the drive mechanism drives the driven wheel to rotate, the driven wheel drives the rotating shaft to rotate, and the rotating shaft drives the pot body to rotate, causing the pot body to tilt, thereby pouring out the syrup. After the syrup is discharged, the drive mechanism drives the pot body to return to its original position, the splash guard is installed to block the edge of the opening at the top of the pot body, and then the stirring motor is started to drive the rotating shaft and stirring scraper to rotate. At the same time, clean water is introduced into the duckbill nozzle, and the clean water is sprayed out in a vertical flat fan shape through the duckbill nozzle. The water mist acts on the stirring shaft inside the pot body, and with the rotation of the stirring shaft, it can thoroughly wash the sugar film on the stirring shaft. After rinsing, water flows into the pot. The speed of the stirring shaft is increased by the gearbox. Combined with the stirring and pushing action of the stirring scraper and the hemispherical inner wall structure of the pot, the water is evenly coated onto the entire inner wall under centrifugal force, continuously washing away and dissolving the sugar film on the inner wall. The splash guard effectively prevents water from overflowing from the pot's edges. When the water level is high enough to cover both the connection between the stirring shaft and the stirring scraper, and the entire inner wall of the pot, adding water stops. Compared to the traditional method of filling the entire pot with water, this method is faster and uses less water. After one cleaning cycle, the pot is tilted by the drive mechanism, and one half of the splash guard is removed, allowing water to drain from the removed area. The cleaning process is repeated once more. The second time, the motor is reversed, essentially completing the cleaning of the pot.

[0010] Compared to traditional cleaning methods and sugar boiling equipment structures, this device uses less water during cleaning, is less likely to create blind spots, and prevents wastewater from splashing onto the outside of the pot. It is also easy to operate, as operators do not need to get close during the cleaning process, thus avoiding injury from high temperatures.

[0011] A further technical solution is that the bottom surface of the stirring scraper is a first arc-shaped surface, which slides and adheres to the inner wall of the pot. The top surface of the stirring scraper is a second arc-shaped surface. The two ends of the first arc-shaped surface and the two ends of the second arc-shaped surface are connected to each other to form a scraping edge. The scraping edge slides and adheres to the inner wall of the pot. The bottom of the stirring shaft is connected to the center of the second arc-shaped surface.

[0012] When using the above solution, the first arc-shaped surface can effectively fit the inner wall of the pot, and the combination of the scraper and the second arc-shaped surface allows water to flow along the second arc-shaped surface when pushed, making it easy to clean the top surface of the stirring scraper.

[0013] A further technical solution is that the splash-proof half-cover is a semi-circular ring.

[0014] When using the above solution, by designing a semi-circular splash-proof half-cover, one can produce only one specification so that the two can be used together, saving production costs, and it is also convenient for personnel to place.

[0015] A further technical solution is that the middle part of the bottom surface of the anti-splash half-covers the upper surface of the pot body, the outer edge of the bottom surface of the anti-splash half-cover protrudes downward to form a semi-circular flange for locking the upper part of the outer wall of the pot body, and the inner edge of the bottom surface of the anti-splash half-cover forms an arc surface obliquely upward, and the tangent direction of the end of the arc surface near the stirring shaft points obliquely downward to the stirring shaft.

[0016] When using the above solution, the flange can effectively hold the pot body and form a stable position. The tangent direction of the end of the arc surface near the stirring shaft is obliquely downward and points to the stirring shaft, which can effectively guide the water that is thrown by centrifugal force back into the pot body in an orderly manner to achieve rinsing and cleaning from top to bottom.

[0017] A further technical solution is that the drive mechanism includes a drive motor fixedly mounted on a support base, and a drive wheel is provided on the output shaft of the drive motor, with the drive wheel driving the driven wheel.

[0018] When using the above scheme, the drive motor drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate.

[0019] A further technical solution is that the driving wheel is a driving gear, the driven wheel is a driven gear, and the driving gear and the driven gear mesh together.

[0020] A further technical solution is that a mounting bracket is also fixed on the support base, and the drive motor is fixed on the mounting bracket.

[0021] A further technical solution is to fix magnetic sheets on the contact surfaces of the two splash-proof half-covers that abut against each other.

[0022] When using the above solution, the magnetic sheet facilitates the quick joining and disassembly of the splash-proof half-cover.

[0023] A further technical solution is to also provide a handle on the outer wall of the splash-proof half-cover.

[0024] When using the above solution, the handle facilitates the quick installation and removal of the splash-proof half-cover.

[0025] The beneficial effects of this utility model are as follows:

[0026] 1. Water-saving and efficient cleaning method: Water mist is sprayed vertically in a flat fan shape through the duckbill nozzle, which, together with the rotation of the stirring shaft, thoroughly washes the sugar film on the stirring shaft. Combined with the stirring scraper and the hemispherical inner wall structure of the pot, water is evenly coated and washed away under centrifugal force, dissolving the sugar film on the inner wall of the pot. Simultaneously, the first arc-shaped surface effectively adheres to the inner wall of the pot, and the combination of the scraper edge and the second arc-shaped surface facilitates cleaning of the top surface of the stirring scraper.

[0027] 2. Less water is used during the cleaning process, making it more water-saving than traditional methods.

[0028] 3. Anti-splash design: The anti-splash cover effectively prevents water from overflowing from the edge of the pot, avoiding wastewater splashing to the outside of the pot during the cleaning process. The curved surface effectively guides the water that is thrown away by centrifugal force back to the inside of the pot in an orderly manner, achieving orderly rinsing and cleaning.

[0029] 4. No dead corners to clean: It is not easy to create dead corners during the cleaning process, ensuring that the inside and outside of the pot are cleaned thoroughly.

[0030] 5. Convenient and safe to operate: The operation process is convenient. During the cleaning process, the operator only needs to quickly install the splash cover and leave to avoid being injured by prolonged high temperature. Attached Figure Description
