Abstract
Description
Technical Field
[0001] This utility model relates to the field of chocolate processing technology, specifically to a melt-proof polishing device for chocolate processing. Background Technology
[0002] Chinese patent CN212351592U discloses a polishing device for chocolate production, comprising a polishing machine body. The polishing machine body includes a cleaning mechanism, a buffer mechanism, and a polishing cylinder. The polishing cylinder is located on one side of the polishing machine body. The cleaning mechanism is located on the same side of the polishing machine body relative to the inner side of the polishing cylinder. The buffer mechanism is located on the outer side of the bottom of the polishing cylinder relative to the lower half of the polishing machine body. This invention, by incorporating a cleaning mechanism, facilitates cleaning of the inner wall of the polishing cylinder during polishing operations and allows for the unified collection of residues, effectively improving the polishing effect of the polishing machine and reducing the labor intensity of the workers. The buffer mechanism cushions the polishing cylinder, preventing damage from frequent impacts with the buffer plate B and effectively extending the service life of the polishing cylinder.
[0003] However, the coordinated operation of multiple mechanisms in this patent may generate heat that is conducted to the polishing cylinder. At the same time, without isolating the hot air from the outside, when the external ambient temperature is high and the machine itself generates heat during operation, the temperature inside the polishing cylinder will rise, causing the chocolate to melt during processing and preventing it from forming properly. Utility Model Content
[0004] The purpose of this invention is to provide a melt-proof polishing device for chocolate processing, which adopts a "two-isolation, one-cooling" method to prevent chocolate from melting, thus solving the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A chocolate processing anti-melting polishing device includes a polishing machine body. One side of the polishing machine body is provided with an inclined surface, and a polishing cylinder is installed on the inclined surface. The bottom of the polishing cylinder is connected to a drive motor inside the polishing machine body through a roller shaft. An inlet is provided on the outer side of the polishing cylinder, and an air supply ring is arranged around the inlet. An air outlet nozzle is arranged in a ring array on the side of the air supply ring facing the bottom of the polishing cylinder. The air outlet nozzle has an air outlet direction perpendicular to the bottom surface of the polishing cylinder.
[0007] The air supply ring is connected to air supply pipes on both sides, and the air supply pipes penetrate the polishing machine body and are connected to the internal cold air system.
[0008] A water-cooled box is also provided on the inclined surface. The water-cooled box is connected to the water-cooling circulation device inside the polishing machine body through an inlet pipe and an outlet pipe. The bottom side of the polishing cylinder is immersed in the coolant in the water-cooled box.
[0009] Preferably, the feed inlet is provided with an arc-shaped edge plate for blocking coolant from flowing into the feed inlet, and the arc-shaped edge plate and the polishing cylinder are an integral structure.
[0010] Preferably, the number of air outlet nozzles is not less than 10 and they are arranged in a ring array.
[0011] Preferably, the water-cooled box is provided with splash-proof baffles on both sides of the top of the inclined surface.
[0012] Preferably, the air outlet nozzle is in contact with the feed inlet.
[0013] Preferably, the air velocity of the air outlet nozzle is set to 2.5-4 m / s, and the nozzle diameter is 3 mm.
[0014] Preferably, the coolant is a 50% propylene glycol aqueous solution.
[0015] Preferably, the water inlet pipe is equipped with a temperature sensor.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention prevents chocolate from melting by employing a "two-isolation, one-cooling" method. Cold air is blown into the air supply ring through an air supply duct and then blown out through air outlet nozzles. The airflow from several air outlet nozzles merges into a ring-shaped vertical air curtain. On the one hand, this isolates the polishing area where the chocolate raw material is located from the outside hot air, preventing the hot air from melting the chocolate raw material. On the other hand, the vertical air curtain continuously cools the bottom surface of the polishing cylinder, isolating the heat generated by mechanical friction during the rotation of the roller shaft and preventing heat from being conducted from the bottom surface to the side wall of the polishing cylinder. Combined with the cooling liquid, the side wall of the rotating polishing cylinder is cooled, thereby maintaining the temperature within the polishing area. This effectively prevents the chocolate raw material from melting and keeps the processing temperature within the optimal range. Furthermore, the structure is simple and effectively reduces production costs. Attached Figure Description

[0022] 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.
[0023] To address the issue of chocolate raw materials potentially melting during processing in existing technologies, the following technical solution is provided. Please refer to [link / reference]. Figure 1-3 ;
[0024] A chocolate processing anti-melting polishing device includes a polishing machine body 1. An inclined surface 14 is provided on one side of the polishing machine body 1, and a polishing cylinder 2 is provided on the inclined surface 14. The bottom center of the polishing cylinder 2 is connected to a drive motor inside the polishing machine body 1 through a roller shaft.
[0025] The polishing cylinder 2 has an inlet 3 on its outer side, and an arc-shaped edge plate 4 is arranged around the inlet 3. The arc-shaped edge plate 4 and the polishing cylinder 2 are an integral structure. The arc-shaped edge plate 4 can prevent the coolant attached to the outer wall of the polishing cylinder 2 from flowing into the inlet 3.
[0026] An air supply ring 5 is provided inside the feed inlet 3. An air outlet nozzle 6 is arranged around the side of the air supply ring 5 facing the bottom of the polishing cylinder 2. The number of air outlet nozzles 6 is not less than 10, and the air outlet direction is perpendicular to the bottom surface of the polishing cylinder 2.
[0027] The air outlet nozzle 6 is in contact with the feed inlet 3 to reduce the gap between the annular vertical air curtain and the feed inlet 3, and to prevent hot air from entering the polishing zone 9 through the gap.
[0028] Air supply pipes 7 are provided on both sides of the air supply ring 5. One end of the air supply pipe 7 is connected to the air supply ring 5, and the other end is inserted into the polishing machine body 1 and connected to the cold air system installed inside it. The air supply pipe 7 supports the air supply ring 5 at the feed inlet 3. At the same time, the cold air system blows cold air into the air supply ring 5 through the air supply pipe 7 and blows it out through the air outlet nozzle 6.
[0029] The air outlet nozzle 6 is set to a wind speed of 2.5-4 m / s, with each nozzle having a diameter of 3 mm. The airflow from several air outlet nozzles 6 merges into a ring-shaped vertical air curtain, with a continuous air curtain coverage area of 0.35 m². 2 On the one hand, it isolates the polishing zone 9 where the chocolate raw material 8 is located from the outside hot air, preventing the hot air from melting the chocolate raw material 8. On the other hand, the vertical air curtain continuously cools the bottom surface of the polishing cylinder 2, isolates the heat generated by mechanical friction during the rotation of the roller shaft, and prevents the heat from being conducted from the bottom surface to the side wall of the polishing cylinder 2, causing the temperature of the polishing zone 9 to rise.
[0030] A water-cooled box 10 is also provided on the inclined surface 14. A water inlet pipe 11 is provided on one side of the water-cooled box 10, and a water outlet pipe 12 is provided on the other side. The water inlet pipe 11 and the water outlet pipe 12 are connected to the water-cooled circulation device inside the polishing machine body 1. Coolant 13 is input into the water-cooled box 10 through the water inlet pipe 11, so that the bottom side of the polishing cylinder 2 is immersed in the coolant 13. During the rotation of the polishing cylinder 2, its side wall is continuously cooled, thereby maintaining the temperature in the polishing zone 9.
[0031] The top two sides of the water-cooled box 10 near the inclined surface 14 are provided with anti-splash baffles 15 to prevent the polishing cylinder 2 from throwing out the coolant 13 on its surface and contaminating the working environment when it is unscrewed from the water-cooled box 10.
[0032] The coolant is a 50% propylene glycol aqueous solution, which is maintained at 2-5℃ through a plate heat exchanger. The circulation pump flow rate is set to 15L / min. The water inlet pipe 11 is equipped with a temperature sensor. When the temperature of the side wall of the polishing tank 2 is detected to be >8℃, the circulation rate is automatically increased to 20L / min.
[0033] Actual operation results show that, with an ambient temperature of 28℃, relative humidity of 65%RH, initial temperature of chocolate raw material 8 of 12℃, and fat content of 32%, after 4 hours of continuous operation, the temperature in polishing zone 9 is maintained at 14.5-15.8℃, which meets the chocolate processing temperature standard. The vertical air curtain reduces the amount of external hot air penetration by 82%. The temperature gradient at the bottom of the cylinder measured by the infrared thermal imager is ≤3℃ / cm. The water cooling system removes 76% of the mechanical friction heat, effectively preventing the chocolate raw material 8 from melting and maintaining the processing temperature within the optimal range.
[0034] Working principle: This device prevents chocolate from melting by adopting a "two-isolation, one-cooling" method. Specifically, cold air is blown into the air supply ring 5 through the air supply pipe 7 and blown out through the air outlet nozzles 6. The airflow from several air outlet nozzles 6 merges into a ring-shaped vertical air curtain. On the one hand, it isolates the polishing zone 9 where the chocolate raw material 8 is located from the outside hot air, preventing the hot air from melting the chocolate raw material 8. On the other hand, the vertical air curtain continuously cools the bottom surface of the polishing cylinder 2, isolating the heat generated by mechanical friction during the rotation of the roller shaft and preventing heat from being conducted from the bottom surface to the side wall of the polishing cylinder 2. In conjunction with the coolant 13, the side wall of the rotating polishing cylinder 2 is cooled, thereby maintaining the temperature in the polishing zone 9 and preventing the chocolate raw material 8 from melting.
