Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings, wherein the same reference numerals in the drawings denote the same or similar components.
"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.
In this document, "first", "second", etc. do not mean their importance or order, etc., but merely mean that they are distinguished from each other so as to facilitate the description of the document.
For the sake of simplicity, only the parts relevant to the present invention are schematically shown in the drawings, and they do not represent the actual structure as a product.
FIG. 1 is a schematic diagram of an exemplary embodiment of a yogurt cooling system. As shown in fig. 1, the yogurt cooling system comprises a first plate heat exchanger 10, a second plate heat exchanger 20, a regulating valve 30, a temperature sensor 40 and a processor 50. For ease of illustration, arrows are used to indicate the direction of fluid flow in use.
The first plate heat exchanger 10 comprises an ice water channel 11 and a first cooling water channel 12. The second plate heat exchanger 20 comprises a feed channel 21 and a second cooling water channel 22. The outlet end of the first cooling water channel 12 is communicated with the inlet end of the second cooling water channel 22, and the outlet end of the second cooling water channel 22 is communicated with the inlet end of the first cooling water channel 12. The regulating valve 30 can control the flow rate of the fluid entering the ice water channel 11. The temperature sensor 40 is capable of detecting the temperature of the material flowing out of the material passage 21. The processor 50 can issue a control signal based on the temperature sensed by the temperature sensor 40. The regulating valve 30 can regulate the flow rate of the fluid entering the ice water channel 11 according to the control signal.
When the yogurt cooling system works, ice water enters the first plate heat exchanger 10 from the inlet end of the ice water channel 11, and meanwhile, cooling water flows into the first plate heat exchanger 10 from the inlet end of the first cooling water channel 12. The temperature of the ice water is lower than that of the cooling water, heat transfer is performed between the ice water and the cooling water in the first plate heat exchanger 10, the temperature of the ice water is increased, and the temperature of the cooling water in the first cooling water channel is decreased. Then, the ice water flows out from the outlet end of the ice water passage 11, and the cooling water flows out from the outlet end of the first cooling water passage 12 and flows into the second plate heat exchanger 20 through the inlet end of the second cooling water passage 22. At the same time, the yogurt enters the second plate heat exchanger 20 from the inlet end of the material passage 21. The temperature of the yoghurt is higher than the temperature of the cooling water, and the yoghurt and the cooling water are subjected to heat transfer in the second plate heat exchanger 20. The cooled yogurt then flows out of the outlet end of the material passage 21. At this time, the temperature sensor 40 detects the temperature of the cooled yogurt flowing out of the material passage 21, and the processor 50 connected to the temperature sensor 40 sends a control signal to the regulating valve 30 according to the temperature detected by the temperature sensor 40. The regulating valve 30 regulates the flow rate of the fluid entering the ice water passage 11 according to the received control signal.
Specifically, if the temperature of the cooled yogurt is higher than a preset value pre-stored in the processor 50, the processor 50 sends a control signal to the regulating valve 30 to increase the flow rate of the fluid entering the ice water channel 11; if the temperature of the cooled yogurt is lower than a preset value pre-stored in the processor 50, the processor 50 sends a control signal to the regulating valve 30 to reduce the flow of the fluid entering the ice water channel 11; if the temperature of the cooled yogurt is within the preset value range pre-stored in the processor 50, the flow rate of the fluid in the ice water channel 11 is kept unchanged.
The yoghourt cooling system can rapidly adjust the flow of the fluid in the ice water channel 11 by detecting the temperature of the material when the material flows out so as to softly cool the yoghourt, so that the viscosity loss of the yoghourt is small, and the improvement of the product quality is facilitated.
As shown in FIG. 1, in the present exemplary embodiment, the yogurt cooling system further includes a cooling water tank 60. The cooling water tank 60 has a water outlet 61 and a water inlet 62, the water outlet 61 is communicated with the inlet end of the first cooling water passage 12, and the water inlet 62 is communicated with the outlet end of the second cooling water passage 22. The water inlet is located above the water outlet in the height direction of the cooling water tank 60. When the cooling water tank 60 is used, a certain amount of cooling water is stored in the cooling water tank, the water inlet 62 is positioned above the liquid level, and the water outlet 61 is positioned below the liquid level, so that gas in the pipeline can be discharged.
As shown in fig. 1, in the present exemplary embodiment, the yogurt cooling system further includes a cooling water circulation pump 70 connected to the water outlet 61 of the cooling water tank 60 at its inlet end and connected to the inlet end of the first cooling water channel 12 at its outlet end, so that the water in the cooling water tank 60 is pumped into the first cooling water channel 12. In the illustrative embodiment, the cooling water circulation pump is a gram-rich circulation pump CM 10-2. But not limited thereto, other cooling water circulation pumps may be selected according to actual needs.

In the present exemplary embodiment, the second plate heat exchanger 20 is a horizontal corrugated plate heat exchanger of south china, shanghai. But not limited thereto, other plate heat exchangers may be selected according to actual needs. In the height direction of the second plate heat exchanger 20, the inlet end and the outlet end of the material channel 21 both correspond to fluid ports at the lower end of heat exchange fins (not shown) of the second plate heat exchanger 20, so as to facilitate emptying of the yogurt in the second plate heat exchanger 20 at the end of production.
