Description

Technical Field

[0001] The present invention relates to the technical field of dairy product processing, and more particularly to a rapid cooling device for dairy product processing and a temperature control method thereof. Background Art

[0002] A large amount of fresh milk is needed in the dairy processing process. In order to ensure the quality of milk, the milk sources are mostly located in places with good environment and no pollution. As a result, most of the milk sources are relatively scattered, and many dairy production and processing centers are far away from the milk sources. It takes a long time to transport the squeezed fresh milk to the factory, which is not conducive to the preservation of the milk source and ensuring the quality of the milk source; especially the freshly squeezed fresh milk, if it cannot be cooled in time, it is easy to deteriorate when the ambient temperature is high, thereby affecting the quality of the fresh milk; in order to ensure the quality of the fresh milk from squeezing to the processing center, the fresh milk needs to be quickly cooled when it is squeezed, and then continuously transported in a low-temperature cold chain throughout the process to ensure that every drop of fresh milk is of pure quality.

[0003] The rapid cooling device for fresh milk is a device used to quickly cool fresh milk from room temperature to below 4°C. At present, the cooling devices for fresh milk on the market are mostly composed of a refrigeration unit, a refrigerant circulation system, a cooling coil, a temperature control system, etc. During use, the fresh milk is mostly passed through the cooling coil and the refrigerant circulation system for heat exchange, so that the temperature of the fresh milk is reduced after passing through the refrigerant circulation system. Although the above-mentioned cooling device can achieve the cooling operation of fresh milk, it is found during use that when the amount of fresh milk that needs to be cooled is large or the amount of fresh milk flowing through the refrigerant circulation system is large, the fresh milk cannot fully contact the refrigerant circulation system, resulting in poor cooling effect and the need for circulation cooling. As a result, the ordinary cooling device has low cooling efficiency for fresh milk, resulting in a long cooling time for fresh milk, which is not conducive to the preservation of fresh milk.

Specific embodiment 1

[0049] See also Figure 1-11 Structural schematic diagram, the present invention provides the following technical solutions:

[0050] Specifically, it refers to a rapid cooling device for dairy product processing, including a cooling cylinder 1 and an upper end cover 2. An atomizing cylinder 3, a support frame 4, and a liquid collecting cover 5 are arranged in sequence from top to bottom between the bottom of the upper end cover 2 and the top of the cooling cylinder 1. The top of the support frame 4 is rotatably connected to a wind wheel 6 extending into the interior of the atomizing cylinder 3. A cooling structure 7 is installed on the top of the support frame 4. The wind wheel 6 is sleeved on the outside of the cooling structure 7 and is coaxial with the cooling structure 7. The liquid after passing through the wind wheel 6 is splashed onto the cooling structure 7. The cooling structure 7 exchanges heat with the emulsion splashed thereon, further improving the cooling efficiency of the emulsion.

[0051] The atomizing tube 3 is penetrated by a high-pressure spray structure 8 extending to the interior of the atomizing tube 3. The bottom of the liquid collecting cover 5 is installed with a heat exchange tube 9 connected to the liquid collecting cover 5 and extending to the interior of the cooling tube 1. The bottom end of the heat exchange tube 9 penetrates the cooling tube 1 and extends to the outside of the cooling tube 1. Two exhaust pipes 10 are installed on the top of the upper end cover 2, wherein the exhaust pipes 10 discharge the gas input into the interior of the atomizing tube 3. The top of the cooling structure 7 penetrates the upper end cover 2 and extends to the top of the upper end cover 2. A through hole is provided on the top of the upper end cover 2 to cooperate with the return pipe 702 and the delivery pipe 703. A pressure relief valve 14 is installed on one of the exhaust pipes 10. The pressure relief valve 14 plays a safety protection role when the internal environmental pressure is too high. A temperature sensor 15 is installed on the other exhaust pipe 10 to monitor the internal environmental temperature of the atomizing tube 3.

[0052] A water injection pipe 11 is fixed at the bottom of the cooling cylinder 1, which is connected to the inner cavity of the cooling cylinder 1 and penetrated by the heat exchange tube 9. A liquid level gauge 12 and a drain pipe 13 are fixed on the outer surface of the cooling cylinder 1, which are used to detect the liquid level of the low-temperature medium inside the cooling cylinder 1 to ensure that the heat exchange tube 9 is in the low-temperature medium; the drain pipe 13 is used to discharge the low-temperature medium whose temperature has increased after use, so as to keep the temperature of the low-temperature medium inside the cooling cylinder 1 constant.

[0053] like Figure 2 、 4 As shown in Figures 10 and 10, the high-pressure spray structure 8 includes a high-pressure air pipe 801 that passes through the mounting sleeve 303 and extends to the inside of the atomizing tube 3. A conical diffusion cover 802 is fixed to one end face of the high-pressure air pipe 801 located inside the atomizing tube 3. A limiting strip 803 that cooperates with the limiting groove is fixed on the outer circumferential surface of the high-pressure air pipe 801. An emulsion delivery pipe 804 with one end extending to the inside of the conical diffusion cover 802 is passed through the high-pressure air pipe 801 along the axis.

[0054] The working principle of the rapid cooling device for dairy product processing provided by the present invention is as follows:

[0055] Working principle: First, the cooling medium is input into the cooling cylinder 1 and the cylinder body 701 respectively through the water injection pipe 11 and the delivery pipe 703 (the temperature required to cool the fresh milk is controlled by controlling the temperature of the cooling medium). The cooling medium fills the cooling cylinder 1 and the cylinder body 701 and makes the temperature inside the atomizing cylinder 3 consistent with the cooling medium and constant for a period of time, so that the temperature inside the atomizing cylinder 3 and the cooling cylinder 1 remains constant.

[0056] Secondly, high-pressure low-temperature gas is introduced through the high-pressure gas pipe 801 in the high-pressure spray structure 8, and the emulsion to be cooled is input through the emulsion delivery pipe 804. The high-pressure low-temperature gas and the emulsion are simultaneously introduced into the atomizing barrel 3; under the action of the high-pressure low-temperature gas (the low-temperature gas can be an inert gas or clean air that has been filtered multiple times. In this application, nitrogen is preferred. The use of low-temperature gas can preliminarily cool the emulsion when mixed with the emulsion, thereby increasing the cooling rate), the emulsion input through the emulsion delivery pipe 804 will be atomized and ejected toward the wind wheel 6 at a higher flow rate, while driving the wind wheel 6 to rotate, so that the emulsion is atomized into finer particles, fully contacting with the cold air in the atomizing barrel 3, so that the emulsion is quickly cooled; the emulsion with larger atomized particles after passing through the wind wheel 6 adheres to the outer surface of the cylinder 701 and the heat absorption plate 704 in the cooling structure 7, further cooling the emulsion.

[0057] After atomization and cooling, the emulsion falls under the action of natural gravity and gathers in the liquid collecting cover 5, then enters the heat exchange tube 9, and passes through the cooling medium in the cooling cylinder 1 under the action of the heat exchange tube 9 to be cooled again; after rapid cooling, the emulsion is output from the cooling cylinder 1 through the lower metal conduit 903 in the heat exchange tube 9, realizing a rapid cooling operation of the emulsion. Specific embodiment 2

[0059] Based on the first specific embodiment, the difference of this embodiment is that:

[0060] like Figure 3 、 4 As shown in FIG. 8 and FIG. 9 , the cooling structure 7 includes a cylinder 701 mounted on the support frame 4. A return pipe 702 and a delivery pipe 703 communicating with the inner cavity of the cylinder 701 are fixed on the top of the cylinder 701. The tops of the return pipe 702 and the delivery pipe 703 pass through the upper end cover 2 and extend to the outside of the upper end cover 2. The bottom of the delivery pipe 703 extends to the bottom of the cylinder 701. A plurality of heat absorbing sheets 704 are passed through the outer circumference of the cylinder 701. One end of the heat absorbing sheet 704 located inside the cylinder 701 is fixed with a heat conducting sleeve 705 matching the inner cavity of the cylinder 701. The heat-conducting sleeve 705 is provided with a drainage groove 706 facing the heat-absorbing sheet 704. The drainage groove 706 extends to the inside of the heat-absorbing sheet 704. The low-temperature medium for cooling the emulsion is input into the cylinder 701 through the delivery pipe 703. The used low-temperature medium is circulated back through the return pipe 702. The low-temperature medium enters the heat-absorbing sheet 704 through the drainage groove 706 to increase the contact area between the emulsion to be cooled and the low-temperature medium. At the same time, the heat-absorbing sheet 704 improves the cooling efficiency of the air inside the atomizing tube 3, thereby improving the cooling efficiency of the emulsion.

[0061] like Figure 2 、 4As shown in Figures 6 and 7, the support frame 4 includes a support ring 401 fixedly connected to the cooling cylinder 1 by bolts, a lower conical support seat 402 rotatably connected to the wind wheel 6 is fixed on the support ring 401, and a lower limit bracket 403 for supporting the cylinder body 701 is fixed on the inner surface of the support ring 401.

[0062] An upper conical support seat 301 rotatably connected to the wind wheel 6 is fixed on the inner circular surface of the atomizing barrel 3, and an upper limit bracket 302 cooperating with the barrel body 701 is fixed on the top end face of the atomizing barrel 3. A mounting sleeve 303 connected to the inner cavity of the atomizing barrel 3 and cooperating with the high-pressure spray structure 8 is fixed on the atomizing barrel 3. A limiting groove is provided on one end face of the mounting sleeve 303 located on the outside of the atomizing barrel 3. The mounting sleeve 303 is used to install the high-pressure spray structure 8. The atomizing barrel 3 provides sufficient atomization and cooling space for the sprayed emulsion, so that the liquid can fully contact the cold air inside the atomizing barrel 3. Specific embodiment three

[0064] Based on the second specific embodiment, the difference of this embodiment is that:

[0065] like Figure 2 、 4 As shown in Figures 11 and 12, the heat exchange tube 9 includes a middle section of a metal spiral tube 901. The input end of the metal spiral tube 901 is fixed with an upper metal conduit 902 connected to the liquid collecting cover 5. The output end of the metal spiral tube 901 is fixed with a lower metal conduit 903 that passes through the water injection pipe 11. A solenoid valve 904 is installed at the connection between the output end of the metal spiral tube 901 and the lower metal conduit 903. The spiral shape of the middle section increases the contact area between the heat exchange tube 9 and the cooling medium inside the cooling cylinder 1, thereby improving the cooling efficiency of the emulsion.

[0066] like Figure 2 、 4 As shown in Figures 7 and 8, the impeller 6 includes two fixing rings 601 that cooperate with the lower conical support seat 402 and the upper conical support seat 301. A plurality of connecting plates 602 are equidistantly mounted in a circular pattern between the two fixing rings 601. The connecting plates 602 are tilted toward the inner circumference of the fixing rings 601. When the impeller 6 is rotated by the high-pressure gas, the connecting plates 602 further disperse the emulsion sprayed from the emulsion delivery pipe 804, thereby atomizing the emulsion into finer particles, which are then fully exposed to the cold air in the atomizing barrel 3, thereby rapidly cooling the emulsion.

[0067] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all included in the scope of protection of the present invention.
