Description

Technical Field

[0001] The utility model relates to the technical field of cheese production equipment, in particular to a cheese production cooling device. Background Art

[0002] Cooling is an important part of the cheese production process. By cooling the cheese to lower its temperature, the metabolic activity of microorganisms can be significantly slowed down, and the growth and reproduction of microorganisms can be inhibited, thereby extending the shelf life of the cheese and preventing it from deteriorating during storage and transportation. Not only that, cooling can also slow down the oxidation and degradation of the cheese, stabilizing the texture and flavor of the cheese. However, ice crystals will form inside the cheese when it is cooled, thus destroying the internal structure of the cheese. Therefore, many manufacturers choose to fill the cheese into vacuum packaging before cooling it to remove moisture from the air and avoid the formation of ice crystals. Vacuum packaging can also prevent oxygen from coming into contact with the cheese, delaying the oxidation process and helping to maintain the texture and taste of the cheese.

[0003] The principles of equipment for cooling cheese using coolant can be roughly divided into two types. One is to spray coolant and use liquid evaporation to absorb environmental heat to achieve the effect of cooling the cheese. The other is to immerse the vacuum-packed cheese in the coolant for direct contact heat exchange. Compared with the second method, the cooling speed of the first method is slower, and it is impossible to ensure that the cheese is evenly cooled on the side close to the spray component and the side away from the spray component. The uneven cooling of the front and back sides of the cheese will affect the uniformity of the cheese texture and reduce the quality of the cheese. In the second method, the temperature of the coolant in contact with the cheese rises during the heat transfer process. Therefore, as the temperature of the cheese decreases, the cooling speed of this method will also decrease, and it is not convenient to smoothly take out batches of cheese. Therefore, it is urgent to provide a cooling device that can ensure that the cheese is evenly cooled, increase the cooling speed, and facilitate the smooth removal of cooled cheese. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a cheese production cooling device, including a cabinet and a liquid storage tank, wherein a plurality of placement rooms are arranged inside the cabinet, a cold water channel is formed between the inner wall of the cabinet and the outer wall of the placement room, the liquid storage tank and the cold water channel are connected through a water inlet pipe, a water pump is arranged on the water inlet pipe, a circulation pipe is connected to the side of the cold water channel away from the water inlet pipe, the other end of the circulation pipe is connected to the top of the liquid storage tank, a circulation pump is installed on the circulation pipe, a holding component is plugged into the bottom side of each of the placement rooms, a one-way water inlet valve is arranged on one side of the top of each of the placement rooms, a one-way water outlet valve is arranged on the other side of each of the placement rooms, and the liquid storage tank is provided with a refrigeration component.

[0006] It should be noted in the solution that an inverted T-shaped groove is provided on the bottom side of each placement room; correspondingly, the bottom of the containing component is an inverted T-shaped convex strip.

[0007] It is further worth explaining that there are multiple containing components, and the containing components include a hollow support plate and a side plate. The two ends of the hollow support plate are respectively fixed to the side plates. The bottom of the side plate is an inverted T-shaped convex strip. A horizontal plate is fixed on the top side of the side plate. The horizontal plate is provided with a groove corresponding to the horizontal edge of the inverted T-shaped convex strip.

[0019] The core of the utility model is to provide a cheese production cooling device, which solves the problems that uneven cooling of cheese affects the uniformity of cheese texture, the cooling speed is not good, and it is not convenient to take out the cheese in batches smoothly after cooling.

[0020] Figure 1 This is a schematic diagram of the structure of a cheese production cooling device provided by the utility model.

[0021] Example 1

[0022] A cheese production cooling device, comprising a cabinet 1 and a liquid storage tank 2 storing a cooling liquid, Figure 1 , a plurality of placement rooms 3 are arranged inside the cabinet 1. In the actual installation process, an entire placement room 3 can be arranged in the cabinet 1, and then the entire large placement room 3 can be divided into a plurality of independent small placement rooms 3 by arranging partitions inside the cabinet 1. Alternatively, a placement room 3 can be arranged at the bottom of the cabinet 1, and then other placement rooms 3 can be stacked and fixed thereon in sequence. A holding component 9 is plugged into the bottom side of each placement room 3. The cheese to be cooled is placed on the holding component 9, the cabinet door of the cabinet 1 is opened, and the holding component 9 is lifted and pressed against the bottom side of the placement room 3 to push the holding component 9 into the placement room 3. During the pushing process, the bottom side of the holding component 9 is plugged into the bottom side of the placement room 3, so that the cheese can be kept in the cooling process. To ensure the placement stability of the cheese, it is also convenient for the staff to directly and smoothly take out all the cooled cheese on the holding component 9 by taking out the entire holding component 9 after cooling. Specifically, an inverted T-shaped groove 13 is provided on the bottom side of each placement room 3, and correspondingly, the bottom of the holding component 9 is an inverted T-shaped convex strip 14. The inverted T-shaped convex strip 14 at the bottom of the holding component 9 is aligned with the inverted T-shaped groove 13 and pushed into the inverted T-shaped groove 13, so that the holding component 9 can be firmly placed in the placement room 3. The cheese to be cooled is separated from the bottom side of the placement room 3 by the holding component 9, so that the upper and lower sides of the cheese can be in contact with the cooling liquid, thereby ensuring that the cheese is evenly cooled and the uniformity of the cheese texture is guaranteed.

[0023] A cold water channel 4 is formed between the inner wall of the cabinet 1 and the outer wall of the storage room 3, see Figure 1The liquid storage tank 2 is connected to the cold water channel 4 through an inlet pipe 5. A water pump 6 is provided on the inlet pipe 5. When the water pump 6 is started, the coolant in the liquid storage tank 2 enters the cold water channel 4 through the inlet pipe 5. A one-way inlet valve 10 is provided on one side of the top of each placement room 3. The coolant in the cold water channel 4 enters each placement room 3 through the one-way inlet valve 10. The coolant entering the placement room 3 contacts the cheese on the holding component 9 in all directions to absorb heat, and the temperature of the cheese itself is continuously reduced, thereby achieving a cooling effect. A one-way outlet valve 11 is provided on the other side of each placement room 3. When the one-way outlet valve 11 is opened, the coolant with a temperature increased after heat transfer flows out of the placement room 3 from the one-way outlet valve 11 and enters the cold water channel 4 away from the side of the inlet pipe 5. A circulation pipe 7 is connected to the side of the cold water channel 4 away from the inlet pipe 5. The other end of the circulation pipe 7 is connected to the top of the liquid storage tank 2. There is a circulation pump 8. When the circulation pump 8 is started, the coolant after heat transfer then flows back to the inside of the liquid storage tank 2 from the top of the liquid storage tank 2 through the circulation pipe 7. The liquid storage tank 2 is provided with a refrigeration component 12. The returned coolant can be refrigerated by the refrigeration component 12 and then recycled for use. The refrigeration component 12 can be but is not limited to a freezer, a refrigerator, a chiller, or the like that can reduce the temperature of the coolant to a specified low temperature. It should be noted that while the flowing coolant enters the placement room 3 and directly exchanges heat with the cheese to be cooled, the coolant in the cold water channel 4 can absorb the heat in the placement room 3, and indirectly assist in cooling the cheese by lowering the overall temperature of the placement room 3. In actual operation, the initial temperature of the coolant can be combined with the trend of the cooling rate of the cheese. Before the cooling rate begins to decrease, the circulating coolant can be started for cooling again. The number of cooling cycles depends on the cooling temperature that the cheese needs to reach.

[0024] Further, in order to improve the utilization rate of the unit placement room 3, the number of the containing components 9 is multiple, see Figure 1 and Figure 2The holding component 9 includes a hollow support plate 900 and a side plate 910. The two ends of the hollow support plate 900 are respectively fixed to the side plates 910. The bottom of the side plate 910 is an inverted T-shaped convex strip 14. When the side plate 910 is held to push the holding component 9 into the placement room 3, the bottom of the side plate 910 and the inverted T-shaped groove 13 on the bottom side of the placement room 3 are inserted into each other. The cheese is placed on the upper side of the hollow support plate 900. The side plate 910 leaves a space between the hollow support plate 900 and the bottom side of the placement room 3. Yes, there are gaps between the front and rear sides of the holding component 9 in the vertical direction and the inner wall of the placement room 3, so that the coolant can flow into the area between the hollow support plate 900 and the bottom side of the placement room 3. When the coolant enters the placement room 3, it can overflow the top and bottom of the hollow support plate 900, thereby ensuring that the front and back sides of the cheese placed on the hollow support plate 900 can contact the coolant, and the coolant can directly contact the back side of the cheese through the hollow part of the hollow support plate 900 for heat exchange, so as to ensure that the cheese is fully and evenly cooled. A horizontal plate 920 is fixed to the top side of the side plate 910, and a groove 930 corresponding to the horizontal side of the inverted T-shaped convex strip 14 is provided on the horizontal plate 920. Through the horizontal plate 920 on the top side of the side plate 910 and the groove 930 on it, another containing component 9 can be stacked and inserted on top of the previous containing component 9, so as to maximize the use of the space of the unit placement room 3. Specifically, the first containing component 9 is placed in a certain placement room 3, and after the bottom of the side plate 910 is plugged into the bottom side of the placement room 3, the second containing component 9 can be held. The side plate 910 of the component 9 is configured so that the horizontal edge of the inverted T-shaped convex strip 14 at the bottom of the side plate 910 is inserted into the groove 930 of the horizontal plate 920 of the first holding component 9, so that the two holding components 9 can be firmly stacked. Similarly, a corresponding number of holding components 9 can be stacked according to the height of each placement room 3, thereby increasing the number of cheeses that can be cooled in the same batch in the unit placement room 3. After the cheese is cooled, the holding components 9 are slid out from high to low in turn to complete the removal of the cooled cheese on each holding component 9.

[0025] Example 2

[0026] Based on Example 1, a preferred embodiment of the hollow support plate 900 is that the hollow support plate 900 is evenly distributed with holes 15 corresponding to the shape of cheese, see Figure 3The edge of each hole groove 15 is in conflict with the edge of the cheese, and the shape of the hole groove 15 corresponds to the shape of the cheese, which can make the cheese close to the side of the hollow support plate 900 directly contact with the coolant with the maximum area, and the edge of the cheese is stuck against the edge of the hole groove 15 to prevent the cheese from falling from the hole groove 15. It is further worth mentioning that the height of the outer edge of the hole groove 15 is higher than the height of the inner edge of the hole groove 15. This design can form a sinking groove, thereby further ensuring the placement stability of the cheese. It is further worth mentioning that the hole groove 15 of the hollow support plate 900 can prevent the coolant from accumulating on the hollow support plate 900, and it is also convenient to drain the coolant remaining on the surface of the cheese packaging to avoid the residual coolant causing bacterial growth.

[0027] For some possible implementations, see Figure 1 A control valve 16 is installed at the connection between the circulation pipe 7 and the cold water channel 4. The liquid storage tank 2 and each storage room 3 are provided with a water temperature sensor 17. The water temperature sensor 17 of each storage room 3 can detect the temperature of the coolant in the storage room 3, so as to infer the cooling temperature that the cheese can reach. When the temperature of the coolant in the storage room 3 rises, the control valve 16 is opened, and the coolant in the storage room 3 can flow back to the liquid storage tank 2 through the circulation pipe 7 for re-cooling. After the water temperature sensor 17 of the liquid storage tank 2 detects that the coolant has dropped to the specified temperature again, the water pump 6 is started to circulate the coolant again. Valve 16 and water temperature sensor 17 can ensure the temperature of the coolant more accurately, thereby further refining and ensuring that the cheese is cooled at a stable cooling temperature, avoiding temperature fluctuations during the cooling process that may affect the quality and taste of the cheese. Preferably, the outer walls of the cabinet 1 and the liquid storage tank 2 are both provided with a heat insulation layer 18. The heat insulation layer 18 can avoid the influence of the external environment temperature on the coolant temperature, thereby improving the stability of the coolant temperature. It should be noted that the coolant can be, but is not limited to, water, Freon, ethanol, ethylene glycol, propylene glycol and other coolants with good heat absorption properties.

[0028] The utility model inserts a holding assembly 9 for holding cheese to be cooled into the bottom side of each storage room 3, starts a water pump 6 on a water inlet pipe 5, and the coolant in the liquid storage tank 2 enters the cold water channel 4 between the inner wall of the cabinet 1 and the outer wall of the storage room 3 through the water inlet pipe 5, and then flows into the storage room 3 from a one-way water inlet valve 10 on one side of the top of each storage room 3. After the coolant contacts and exchanges heat with the cheese on the holding assembly 9, it flows into the cold water channel 4 on the side away from the water inlet pipe 5 from a one-way water outlet valve 11 arranged on the other side of the bottom of each storage room 3, and then flows back to the top of the liquid storage tank 2 through a circulation pipe 7, and passes through the refrigeration part of the liquid storage tank 2. After the component 12 is cooled, it can be recycled again. Through the holding component 9, the cold water channel 4, the one-way water inlet valve 10 and the one-way water outlet valve 11, the front and back sides of the cheese to be cooled can be fully in contact with the coolant for heat exchange, and the coolant in the placement room 3 can flow for heat exchange, which can avoid the cooling speed being affected by the increase in the temperature of the coolant after contacting the cheese. While ensuring uniform cooling, the flowing coolant can effectively increase the cooling speed. The holding component 9 is inserted into the bottom side of the placement room 3, which also makes it convenient for the staff to directly and smoothly remove all the cooled cheese on the holding component 9 by taking the holding component 9 out of the placement room 3.
