Usually, the liquid poured first is required to have a lower viscosity and be thin and soft to ensure that the bottom can be completely filled during pouring without causing voids. The liquid on the top needs to ensure the flower-shaped structure of the product. The liquid is required to have a high viscosity and be thicker and harder so that the flower shape of the product can have a certain degree of uprightness.

In the process of flowing through the interlayer space, the first heat exchange medium exchanges heat with the feed liquid through the inner cylinder wall, so that the feed liquid is heated up, thereby changing the shape and viscosity of the feed liquid. When the temperature of the first heat exchange medium is high, the feed liquid is heated up more obviously, and the feed liquid becomes relatively thin and soft, and has a lower viscosity; when the temperature of the first heat exchange medium is low or the first heat exchange medium is not passed, the feed liquid is relatively thick and hard, and has a higher viscosity. Therefore, by forming an interlayer space between the inner cylinder wall and the outer cylinder wall, a first heat exchange medium inlet and a first heat exchange medium outlet connected to the interlayer space are provided on the outer cylinder wall. The shape and viscosity of the slurry can be changed by introducing the first heat exchange medium into the interlayer space, and the filling requirements can be met by using only one freezing equipment.

[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Example 1

[0030] At present, in the industrial production of ice cream, a feeding freezer with a capacity of more than 1,000 liters is used for freezing and feeding. Some products that need to be poured and formed twice or more times have different requirements for the state of the liquid. Usually, the liquid poured first is required to have a lower viscosity and be thin and soft to ensure that the bottom can be completely filled during pouring without causing voids. The liquid on the top needs to ensure the flower-shaped structure of the product. The liquid is required to have a high viscosity and be thicker and harder so that the flower shape of the product can have a certain degree of uprightness. Therefore, it is necessary to change the state of the liquid poured once and improve its fluidity so that it can be fully poured and meet the needs of product pouring.

[0031] In the production of high-expansion products, especially those that require two or more injections to form, the total weight of the liquid is usually divided into two or more times, and two freezing devices are used to feed and inject the materials simultaneously. The feed amount of a single freezing device is halved, which not only causes energy loss, but also tests the operating stability of the freezing equipment.

[0032] To this end, this embodiment provides a liquid temperature regulating device, which can change the viscosity of the ice cream liquid, and only one freezing device is used to meet the filling requirements.

[0033] In one embodiment, if Figures 1 to 5 As shown, the liquid temperature regulating device comprises a temperature regulating cylinder 1, the temperature regulating cylinder 1 comprises an inner cylinder wall 101, an outer cylinder wall 102, and a first end plate 103 and a second end plate 104 connected at both ends of the inner cylinder wall 101 and the outer cylinder wall 102. A liquid channel is formed on the inner side of the inner cylinder wall 101, a liquid inlet 105 communicating with the liquid channel is provided on the first end plate 103, and a liquid outlet 106 communicating with the liquid channel is provided on the second end plate 104. The liquid inlet 105 is suitable for contacting with the frozen liquid. The material outlet 106 is connected to the material outlet of the equipment, and the material outlet 106 is suitable for being connected to the material inlet of the perfusion equipment. An interlayer space 107 is formed between the inner cylinder wall 101 and the outer cylinder wall 102. The interlayer space 107 is suitable for accommodating a first heat exchange medium. A first heat exchange medium inlet 108 communicating with the interlayer space 107 is provided on the outer cylinder wall 102 or the first end plate 103, and a first heat exchange medium outlet 109 communicating with the interlayer space 107 is provided on the outer cylinder wall 102 or the second end plate 104.

[0034] In this embodiment, in actual application, the liquid inlet 105 is connected to the discharge port of the freezing device, and the liquid outlet 106 is connected to the feed port of the filling device. The liquid in the freezing device can flow into the liquid channel through the liquid inlet 105, and finally flow into the filling device through the liquid outlet 106. When the shape and viscosity of the liquid need to be adjusted, the first heat exchange medium is allowed to enter the interlayer space 107 through the first heat exchange medium. After the heat exchange is completed, the first heat exchange medium flows out from the first heat exchange medium outlet 109. In the process of flowing through the interlayer space 107, the first heat exchange medium exchanges heat with the liquid through the inner cylinder wall 101, so that the liquid temperature rises and the shape and viscosity of the liquid are changed. When the temperature of the first heat exchange medium is high, the liquid temperature rises significantly, and the liquid becomes relatively thin and soft with low viscosity; when the temperature of the first heat exchange medium is low or the first heat exchange medium is not passed, the liquid is relatively thick and hard with high viscosity. Therefore, by forming an interlayer space 107 between the inner cylinder wall 101 and the outer cylinder wall 102, a first heat exchange medium inlet 108 and a first heat exchange medium outlet 109 connected to the interlayer space 107 are provided on the outer cylinder wall 102. The shape and viscosity of the slurry can be changed by introducing the first heat exchange medium into the interlayer space 107, and the filling requirements can be met by using only one freezing equipment.

[0035] The first heat exchange medium can be gas or liquid. When it is liquid, water is a common raw material, so the first heat exchange medium is preferably water. The form and viscosity of the feed liquid can be changed by adjusting the temperature of the water entering the interlayer space 107, and the water temperature can be adjusted specifically by a heating device and a condensing device.

[0036] On the basis of the above-mentioned embodiments, in a preferred embodiment, the feed liquid temperature regulating device further comprises a temperature changing plate 2, the temperature changing plate 2 is provided with a heat exchange medium channel 201, the heat exchange medium channel 201 is suitable for the second heat exchange medium to pass through, one end of the heat exchange medium channel 201 is a heat exchange medium channel inlet 2011, and the other end is a heat exchange medium channel outlet 2012, the temperature changing plate 2 comprises a heat exchange portion 202 passing through the inner cylinder wall, and the heat exchange portion 202 is provided with a material passage channel 203 suitable for the feed liquid to pass through. In this embodiment, by providing the temperature changing plate 2, since the heat exchange medium channel 201 is provided in the temperature changing plate 2, when the second heat exchange medium flows through the heat exchange medium channel 201, the second heat exchange medium will exchange heat with the heat exchange portion 202, and when the feed liquid flows through the material passage channel 203 and when the feed liquid contacts the side wall of the heat exchange portion 202, the feed liquid will be affected by the temperature of the second heat exchange medium, forming heat exchange, thereby achieving the purpose of changing the temperature and physical state of the feed liquid. By providing the temperature-changing plate 2, the heat exchange effect on the feed liquid can be further improved, and the efficiency of the temperature change and physical state change of the feed liquid can be improved.

[0037] The second heat exchange medium can be either gas or liquid. When it is liquid, water is a common raw material, so the second heat exchange medium is preferably water. The form and viscosity of the liquid can be changed by adjusting the temperature of the water entering the heat exchange medium channel 201, and the water temperature can be adjusted specifically by a heating device and a condensing device.

[0038] On the basis of the above-mentioned embodiments, in a preferred embodiment, a plurality of temperature-changing plates 2 are evenly arranged along the circumference of the inner cylinder wall, and a material passing gap 3 suitable for the passage of the feed liquid is formed between the heat exchange parts 202 of two adjacent temperature-changing plates 2. In this embodiment, by forming a material passing gap 3 between the heat exchange parts 202 of two adjacent temperature-changing plates 2, when the feed liquid flows through the material passing gap 3, the feed liquid contacts the side wall of the material passing gap 3, that is, the side wall of the temperature-changing plate 2, and is affected by the temperature of the second heat exchange medium to form heat exchange, thereby further achieving the purpose of changing the temperature and physical state of the feed liquid. In this embodiment, the heat exchange contact area between the feed liquid and the heat exchange part 202 is increased, which can further enhance the heat exchange effect on the feed liquid and improve the efficiency of the change in the temperature and physical state of the feed liquid. In an alternative embodiment, the temperature-changing plate 2 is annular as a whole. In this embodiment, a large number of material passing channels 203 can be formed on the temperature-changing plate 2.

[0039] like Figure 3 and Figure 4 As shown, the temperature changing plate 2 includes a heat exchange portion 202 extending into the inner side of the inner cylinder wall 101 and a connecting portion 204 located outside the inner cylinder wall 101. A through groove suitable for the connecting portion 204 to pass through is formed on the outer cylinder wall 102, and a through hole suitable for the heat exchange portion 202 to pass through is formed on the inner cylinder wall 101. After the heat exchange portion 202 extends into the inner side of the inner cylinder wall 101, the connecting portion 204 is supported outside the inner cylinder wall 101. To ensure that the connecting portion 204 can be stably supported outside the inner cylinder wall 101, a step surface is formed between the connecting portion 204 and the heat exchange portion 202, and the connecting portion 204 is supported outside the inner cylinder wall 101 through the step surface.

[0040] Further references Figure 3 At the same cross section of the temperature regulating cylinder 1, there are four temperature changing plates 2, the heat exchange portion 202 is in a shape similar to an isosceles trapezoid, including a first end wall 2021 close to the center of the temperature regulating cylinder 1, and an inclined second end wall 2022 connected to both sides of the first end wall 2021. The heat exchange medium channel 201 has a shape adapted to the heat exchange portion 202, and a material passing gap 3 is formed between two adjacent second end walls 2022.

[0041] On the basis of the above-mentioned embodiment, in a preferred embodiment, a plurality of temperature-changing plates 2 are arranged at intervals along the axial direction of the temperature-regulating cylinder 1. In this embodiment, by arranging a plurality of temperature-changing plates 2 at intervals along the axial direction of the temperature-regulating cylinder 1, the feed liquid will contact the temperature-changing plates 2 for heat exchange multiple times during the flow of the feed liquid channel, which can further improve the heat exchange effect of the feed liquid and improve the efficiency of the temperature change and physical state change of the feed liquid.

[0042] Further references Figure 3 A partition 12 is provided on the outer side of the inner cylinder wall 101 and at the same cross-section as the temperature changing plate 2. The partition 12 divides the interlayer space 107 into multiple sections. A heat exchange medium channel 1201 is provided on the partition 12 to connect two adjacent sections.

[0043] On the basis of the above-mentioned embodiment, in a preferred embodiment, a first annular tube 4 and a second annular tube 5 are arranged at intervals outside the temperature regulating tube 1, a second heat exchange medium inlet 401 is provided on the first annular tube 4, a second heat exchange medium outlet 501 is provided on the second annular tube 5, the first annular tube 4 is connected to a plurality of heat exchange medium supply pipes 6, each of which is connected to the heat exchange medium channel inlet 2011 of a plurality of temperature changing plates 2, and the second annular tube 5 is connected to a plurality of heat exchange medium recovery pipes 7, each of which is connected to the heat exchange medium channel outlet 2012 of a plurality of temperature changing plates 2. In this embodiment, the second heat exchange medium flows into the first annular tube 4 through the second heat exchange medium inlet 401, and then flows into multiple heat exchange medium supply pipes 6 after diversion. One heat exchange medium supply pipe 6 can provide the second heat exchange medium for multiple temperature changing plates 2 at the same time. After the second heat exchange medium flows through the heat exchange medium channel 201, it flows out from the heat exchange medium channel outlet 2012. Since a heat exchange recovery pipe is connected to the heat exchange medium channel outlets 2012 of multiple temperature changing plates 2, the second heat exchange medium in the multiple temperature changing plates 2 can be recovered, so that the second heat exchange medium continuously enters through the heat exchange medium channel inlet 2011 and continuously flows out from the heat exchange medium channel outlet 2012. The structure is simple, and it is convenient to uniformly control the temperature of the second heat exchange medium.

[0044] like Figure 3 As shown, at the same cross-section of the temperature regulating cylinder 1, there are four temperature changing plates 2, and in the same axial direction, there are four temperature changing plates 2, and the four temperature changing plates 2 in the same axial direction are located in a row, therefore, a heat exchange medium supply pipe 6 is connected to the heat exchange medium channel inlet 2011 of the four temperature changing plates 2 located in the same row, a heat exchange medium recovery pipe 7 is connected to the heat exchange medium channel outlet 2012 of the four temperature changing plates 2 located in the same row, the first annular pipe 4 is connected to four heat exchange medium supply pipes 6, and the second annular pipe 5 is connected to four heat exchange medium recovery pipes 7.

[0045] On the basis of the above-mentioned embodiments, in a preferred embodiment, a rotating shaft 8 is provided at the center of the temperature regulating cylinder 1, and a plurality of blades 9 are provided on the rotating shaft 8, and the blades 9 are located between two adjacent temperature changing plates 2 distributed along the axial direction, between the temperature changing plate 2 and the first end plate 103, and between the temperature changing plate 2 and the second end plate 104. In this embodiment, when the rotating shaft 8 rotates, the blades 9 can be driven to rotate, which has a certain stirring effect, and can make the feed liquid fully contact with the surface of the heat exchange part 202 of the temperature changing plate 2 and the surface of the material passage 203, and make the feed liquid after heat exchange and temperature change more uniform, so as to ensure the system stability of the feed liquid.

[0046] Of course, the liquid temperature regulating device also includes a driving structure (not shown in the figure) that can drive the rotating shaft 8 to rotate.

[0047] On the basis of the above embodiment, in a preferred embodiment, the blade 9 is spiral-shaped. In this embodiment, the spiral blade 9 can assist the flow of the feed liquid, so that the feed liquid can quickly pass through the feed gap 3 and the feed channel 203.

[0048] On the basis of the above-mentioned embodiment, in a preferred embodiment, the rotating shaft 8 has a hollow channel 801, and the third heat exchange medium is suitable for passing through the hollow channel 801. In this embodiment, when the third heat exchange medium passes through the hollow channel 801, it can further exchange heat with the feed liquid, further improve the heat exchange effect of the feed liquid, and improve the efficiency of the temperature change and physical state change of the feed liquid.

[0049] Specifically, one end of the hollow channel 801 is the third heat exchange medium inlet 802 , and the other end is the third heat exchange medium outlet 803 .

[0050] The third heat exchange medium can be either gas or liquid. When it is liquid, water is a common raw material, so the third heat exchange medium is preferably water. The form and viscosity of the liquid can be changed by adjusting the temperature of the water entering the rotating shaft 8, and the water temperature can be adjusted specifically by a heating device and a condensing device.

[0051] In a preferred embodiment, the first heat exchange medium, the second heat exchange medium, and the third heat exchange medium are the same. In this embodiment, the first heat exchange medium inlet 108, the second heat exchange medium inlet 401, and the third heat exchange medium inlet 802 can be connected to the same heat exchange medium supply source, and the first heat exchange medium outlet 109, the second heat exchange medium outlet 501, and the third heat exchange medium outlet 803 can be connected to the same heat exchange medium recovery box. The temperatures of the first heat exchange medium, the second heat exchange medium, and the third heat exchange medium can be adjusted simultaneously by simply adjusting the temperature of the heat exchange medium in the heat exchange medium supply source.

[0052] On the basis of the above-mentioned embodiments, in a preferred embodiment, the liquid temperature control device further comprises a controller 10, a sensor 11 is provided at the liquid outlet 106, the sensor 11 can detect the temperature and / or viscosity of the liquid, the controller 10 is in communication with the sensor 11, and can calculate the required temperature of the first heat exchange medium, and / or the second heat exchange medium, and / or the third heat exchange medium according to the detection data of the sensor 11 and the preset data.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
