[0001] This utility model relates to the field of candy production technology, specifically to a sugar boiling device for candy production. Background Technology

[0002] Candy is a widely popular sweet treat. It attracts people not only with its sweet taste, but also with its rich texture, diverse shapes and colors, making it an important part of people's daily lives.

[0003] Confectionery production is a complex and multi-step process involving various stages, from raw material selection and formula design to final product packaging. Sugar boiling equipment is a key processing tool in confectionery production, used to heat and concentrate syrup or other sweeteners to the appropriate concentration and temperature to form the desired confectionery product.

[0004] The existing patent document with authorization announcement number CN221634932U describes a sugar boiling device for candy production, including a cylinder with a number of heating tubes fixedly connected to its outer surface and an outer cylinder. In this technical solution, the stirring rod can be threadedly connected to the fixed rod through a threaded head, which facilitates the operator to clean the sugar adhering to the inner wall of the device. However, due to the lack of a preheating and pressure relief device, the temperature of the sugar is low when it is added, and the reaction is slow, resulting in low sugar boiling efficiency. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a sugar boiling equipment for candy production, which solves the problem that the sugar material is added at a low temperature due to the lack of preheating and pressure relief devices, resulting in slow reaction and low sugar boiling efficiency. The steam entering the exhaust pipe flows into the heating layer through the exhaust groove. By setting the exhaust pipe and the exhaust groove, the steam is diverted, improving the uniformity of preheating of the heating layer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sugar boiling device for candy production, comprising a tank assembly, a monitoring assembly, and a stirring assembly. The tank assembly includes a sugar boiling tank cylinder and a preheating gas pipe. The monitoring assembly includes a breather valve and a safety valve. The stirring assembly includes a motor and a rotating shaft. The inner side of the sugar boiling tank cylinder is provided with a heat insulation layer and a heating layer. The inner side of the heating layer is provided with a heating plate, and the outer side of the heating plate is provided with a heat-conducting insulation layer. The top of the preheating gas pipe is connected to an exhaust pipe and an exhaust pipe 2. The lower end of the sugar boiling tank cylinder is connected to a drain pipe. A temperature sensor is installed on one side of the outer wall of the sugar boiling tank cylinder. The outer wall of the rotating shaft is connected with sleeves at equal intervals. The outer ring wall of the sleeves away from the rotating shaft is symmetrically connected with stirring rods.

[0007] The beneficial effects of this utility model are as follows: when steam is injected through the preheating pipe, part of the steam in the preheating pipe flows into the second exhaust pipe, and then the steam flows into the heating layer through the second exhaust pipe. The other part of the steam enters the first exhaust pipe, and then the steam entering the first exhaust pipe flows into the heating layer through the exhaust groove. By setting the first exhaust pipe and the exhaust groove, the steam is diverted, and the uniformity of preheating the heating layer is improved.

[0008] To complete the sugar boiling process, the sugar flows through a guide block into the discharge pipe and is then discharged.

[0009] As a further improvement to the above technical solution: the top of the sugar boiling tank is connected to a feed pipe, the bottom of the sugar boiling tank is connected to a discharge pipe including a valve, and the inner wall of the sugar boiling tank is connected to a guide block.

[0010] The beneficial effects of this improvement are as follows: when in use, the sugar is added through the feed pipe, and the sugar that has completed the sugar boiling process flows into the discharge pipe through the guide block and is discharged.

[0011] To monitor the temperature inside the sugar boiling vessel and ensure the sugar is within the appropriate temperature range:

[0012] As a further improvement to the above technical solution: the breathing valve is installed on the top of the sugar boiling tank and is connected to the inner cavity of the sugar boiling tank. The breathing valve includes a pressure valve and a vacuum valve. The probe of the temperature sensor is located on the inner side of the sugar boiling tank.

[0013] The beneficial effects of this improvement are as follows: When sugar is added to the sugar boiling tank, the pressure in the upper gas space inside the tank increases. When the pressure reaches the positive operating pressure of the breather valve, the pressure valve is opened, and gas escapes from the breather valve outlet, preventing the pressure inside the sugar boiling tank from continuing to increase. When sugar is discharged from the sugar boiling tank, the pressure in the upper gas space inside the tank decreases. When the pressure reaches the negative operating pressure of the breather valve, the atmosphere outside the tank opens the negative pressure valve disc of the breather valve, allowing outside gas to enter the tank, preventing the pressure inside the tank from continuing to decrease, thus balancing the gas pressure inside and outside the tank and preventing deformation of the tank. A temperature sensor is used to monitor the temperature inside the tank, ensuring that the sugar is within a suitable temperature range.

[0014] The heating plate generates heat to indirectly heat the syrup, gradually evaporating the water to achieve the desired concentration:

[0015] As a further improvement to the above technical solution: the thermally conductive insulating layer is connected to the inner wall of the heating layer, and there are two heating plates that are electrically connected to the operation panel.

[0016] The beneficial effects of this improvement are as follows: when the heating plate is started, the heat generated by the heating plate is used to indirectly heat the syrup, so that the water is gradually evaporated to reach the required concentration. At the same time, direct flame contact with the syrup is avoided, reducing the risk of caramelization and local overheating. The heat-conducting insulation layer is used to prevent the introduced steam from affecting the heating plate.

[0017] To monitor the pressure inside the sugar boiling tank and ensure the safe use of the device:

[0018] As a further improvement to the above technical solution: the safety valve is installed vertically upward on the top of the sugar boiling tank by bolts and is connected to the inner cavity of the sugar boiling tank; a pressure gauge is installed on one side of the sugar boiling tank.

[0019] The beneficial effects of this improvement are as follows: by setting a safety valve, the safety valve will automatically open when the pressure exceeds the set value and release the pressure through the safety valve; by setting a pressure gauge, the pressure inside the sugar boiling tank can be monitored to ensure the safe use of the device.

[0020] In order to inject a fixed amount of steam into the heating layer through a preheating pipe, and thus preheat the heating layer through the injected steam:

[0021] As a further improvement to the above technical solution: valves are installed on the preheating gas pipe, drain pipe, and steam port; the top of the preheating gas pipe penetrates the wall of the sugar boiling tank and extends to the inner side of the heating layer; and a steam port connected to the heating layer is provided at one end of the sugar boiling tank.

[0022] The beneficial effects of this improvement are as follows: when the device needs to be preheated, a certain amount of steam is injected into the heating layer through the preheating gas pipe, thereby preheating the heating layer through the injected steam. At the same time, the water droplets formed by the steam cooling in the heating layer remain on the inner wall of the sugar boiling tank and the outer wall of the heating layer. Then the water droplets slide to the bottom of the heating layer and are discharged through the drain pipe.

[0023] In order to achieve steam diversion and improve the uniformity of preheating of the heating layer by setting up an exhaust pipe and an exhaust channel:

[0024] As a further improvement to the above technical solution: the second exhaust pipe is connected to the preheating pipe, and a number of exhaust slots are opened on the inner side of the first exhaust pipe.

[0025] The beneficial effects of this improvement are as follows: when steam is injected through the preheating pipe, part of the steam in the preheating pipe flows into the second exhaust pipe, and then the steam flows into the heating layer through the second exhaust pipe. The other part of the steam enters the first exhaust pipe, and then the steam entering the first exhaust pipe flows into the heating layer through the exhaust groove. By setting the first exhaust pipe and the exhaust groove, the steam is diverted, and the uniformity of preheating the heating layer is improved.

[0026] To ensure the syrup circulates continuously by rotating the stirring rod:

[0027] As a further improvement to the above technical solution: the motor is installed on the top of the sugar boiling tank and electrically connected to the operation panel; the top of the rotating shaft penetrates the wall of the sugar boiling tank and is connected to the output end of the motor through a coupling; a bearing is installed at the position where the rotating shaft penetrates the wall of the sugar boiling tank.

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0036] like Figure 1-5As shown, a sugar-boiling device for candy production includes a tank assembly 1, a monitoring assembly 2, and a stirring assembly 3. The tank assembly 1 includes a sugar-boiling tank cylinder 11 and a preheating gas pipe 17. The monitoring assembly 2 includes a breather valve 21 and a safety valve 22. The stirring assembly 3 includes a motor 31 and a rotating shaft 32. The inner side of the sugar-boiling tank cylinder 11 is provided with a heat insulation layer 14 and a heating layer 15. The inner side of the heating layer 15 is provided with a heating plate 16, and the outer side of the heating plate 16 is provided with a heat-conducting insulation layer 161. The top of the preheating gas pipe 17 is connected to an exhaust pipe 171 and an exhaust pipe 172. The lower end of the sugar-boiling tank cylinder 11 is connected to a drain pipe 174. A temperature sensor is installed on one side of the outer wall of the sugar-boiling tank cylinder 11. The apparatus 24 has sleeves 33 evenly spaced on the outer wall of the rotating shaft 32. Stirring rods 34 are symmetrically connected to the outer ring wall of the sleeves 33 away from the rotating shaft 32. A feed pipe 12 is connected to the top of the sugar-cooking tank 11, and a discharge pipe 13 including a valve is connected to the bottom of the sugar-cooking tank 11. A guide block 25 is connected to the inner wall of the sugar-cooking tank 11. In use, sugar is added through the feed pipe 12, and the sugar that has undergone the sugar-cooking process flows through the guide block 25 into the discharge pipe 13 and is discharged. A breather valve 21 is installed on the top of the sugar-cooking tank 11 and communicates with the inner cavity of the sugar-cooking tank 11. The breather valve 21 includes a pressure valve and a vacuum valve. The probe of the temperature sensor 24 is located on the sugar-cooking tank 11. Inside the sugar-boiling tank 11, when sugar is added, the pressure in the upper gas space increases. When the pressure reaches the positive operating pressure of the breather valve 21, the pressure valve is opened, and gas escapes from the outlet of the breather valve 21, preventing the pressure inside the sugar-boiling tank 11 from increasing further. When sugar is discharged from the sugar-boiling tank 11, the pressure in the upper gas space decreases. When the pressure reaches the negative operating pressure of the breather valve 21, the atmosphere outside the sugar-boiling tank 11 opens the negative pressure valve disc of the breather valve 21, allowing outside gas to enter the tank, preventing the pressure inside the sugar-boiling tank 11 from decreasing further, thus balancing the air pressure inside and outside the sugar-boiling tank 11 and preventing deformation of the sugar-boiling tank 11. The temperature sensor 24 is used to monitor the pressure inside and outside the sugar-boiling tank. The temperature inside cylinder 11 is monitored to ensure that the sugar is within a suitable temperature range. The heat-conducting insulation layer 161 is connected to the inner wall of the heating layer 15. There are two heating plates 16, which are electrically connected to the operation panel. When the heating plates 16 are started, they generate heat to indirectly heat the syrup, gradually evaporating the water to reach the required concentration. At the same time, direct flame contact with the syrup is avoided to reduce the risk of caramelization and local overheating. The heat-conducting insulation layer 161 is used to prevent the introduced steam from affecting the heating plates 16. The safety valve 22 is installed vertically upward on the top of the sugar boiling tank cylinder 11 by bolts and is connected to the inner cavity of the sugar boiling tank cylinder 11. A pressure gauge 23 is installed on one side of the sugar boiling tank cylinder 11.Safety valve 22 automatically opens and releases pressure when the pressure exceeds a set value. Pressure gauge 23 monitors the pressure inside the sugar boiling tank 11 to ensure safe operation. Valves are installed on the preheating gas pipe 17, drain pipe 174, and steam port 26. The top of the preheating gas pipe 17 penetrates the wall of the sugar boiling tank 11 and extends to the inner side of the heating layer 15. A steam port connected to the heating layer 15 is provided at one end of the sugar boiling tank 11. 26; When preheating of the device is required, a certain amount of steam is injected into the heating layer 15 through the preheating gas pipe 17, thereby preheating the heating layer 15. At the same time, water droplets formed by the cooling of the steam in the heating layer 15 remain on the inner wall of the sugar boiling tank 11 and the outer wall of the heating layer 15. Then, the water droplets slide to the bottom of the heating layer 15 and are discharged through the drain pipe 174. The exhaust pipe 172 is connected to the preheating gas pipe 17. Several exhaust slots are opened on the inner side of the exhaust pipe 171. 173; When steam is injected through preheating pipe 17, part of the steam in preheating pipe 17 flows into exhaust pipe 2 172, and then the steam flows into heating layer 15 through exhaust pipe 2 172. The other part of the steam enters exhaust pipe 171, and then the steam in exhaust pipe 171 flows into heating layer 15 through exhaust channel 173. The arrangement of exhaust pipe 171 and exhaust channel 173 achieves steam diversion, improving the uniformity of preheating of heating layer 15. The motor 31 is mounted on top of the sugar-boiling tank 11 and electrically connected to the control panel. The top of the rotating shaft 32 penetrates the wall of the sugar-boiling tank 11 and is connected to the output end of the motor 31 via a coupling. A bearing is installed at the point where the rotating shaft 32 penetrates the wall of the sugar-boiling tank 11. After the motor 31 is started, it operates and drives the sleeve 33 to rotate via the rotating shaft 32. The rotation of the stirring rod 34 causes the syrup to circulate continuously, ensuring uniform temperature distribution and preventing sugar deposition and burning.

[0037] The working principle of this utility model is as follows: When preheating the device is required, a fixed amount of steam is injected into the heating layer 15 through the preheating pipe 17. After the steam is injected through the preheating pipe 17, part of the steam flows into the exhaust pipe 2 172, and then into the heating layer 15 through the exhaust pipe 2 172. The other part of the steam enters the exhaust pipe 171, and then flows into the heating layer 15 through the exhaust channel 173. The arrangement of the exhaust pipe 171 and the exhaust channel 173 achieves steam diversion, improving the heating effect on the heating layer 15. The uniformity of preheating is ensured. Simultaneously, water droplets formed by the cooling of steam within the heating layer 15 remain on the inner wall of the sugar-boiling tank 11 and the outer wall of the heating layer 15. These droplets then slide down to the bottom of the heating layer 15 and are discharged through the drain pipe 174. When sugar is added to the sugar-boiling tank 11, the pressure in the upper gas space increases. When this pressure reaches the positive operating pressure of the breather valve 21, the pressure valve is opened, and gas escapes from the outlet of the breather valve 21, preventing the pressure inside the sugar-boiling tank 11 from further increasing. When sugar is discharged from the sugar-boiling tank 11, the pressure in the upper gas space decreases, reaching the negative operating pressure of the breather valve 21. The outside atmosphere pushes open the negative pressure valve disc of the breather valve 21, allowing outside air to enter the tank and preventing the pressure inside the sugar boiling tank 11 from continuing to drop. This balances the air pressure inside and outside the sugar boiling tank 11, preventing deformation. Temperature sensor 24 monitors the temperature inside the sugar boiling tank 11 to ensure the sugar is within a suitable temperature range. Heating plate 16 is activated, generating heat to indirectly heat the syrup, gradually evaporating moisture to achieve the desired concentration. This avoids direct flame contact with the syrup, reducing the risk of caramelization and localized overheating. The heat is then transferred through the heat-conducting insulation layer 161. The system is designed to prevent the introduced steam from affecting the heating plate 16. After the motor 31 is started, it operates and drives the sleeve pipe 33 to rotate via the rotating shaft 32. The rotation of the stirring rod 34 causes the syrup to circulate continuously, ensuring uniform temperature distribution and preventing sugar deposition and burning. The safety valve 22 automatically opens when the pressure exceeds the set value, releasing the pressure. The pressure gauge 23 is used to monitor the pressure inside the sugar boiling tank 11 to ensure safe use of the device. The sugar that has completed the sugar boiling process flows into the discharge pipe 13 through the guide block 25 and is discharged.
