Description

Technical Field

[0001] This utility model relates to the field of dairy product production, and in particular to an integrated milk sterilization and cooling device. Background Technology

[0002] Milk sterilization is a very important step in the dairy processing of dairy products. Its purpose is to eliminate pathogenic microorganisms and harmful bacteria that may exist in raw milk, thereby ensuring the safety of milk products and extending their shelf life.

[0003] The most common method for milk sterilization is pasteurization. The standard pasteurization process usually involves maintaining the temperature at 63°C for 30 minutes, or heating at 72-85°C for 15 to 20 seconds, followed by rapid cooling to complete the sterilization process.

[0004] However, the existing sterilization and cooling steps are discontinuous, and the two devices operate independently of each other, which can easily lead to waste of resources and increase production costs, and needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated milk sterilization and cooling device, which has the effect of reducing resource waste.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 , Figure 2 As shown, an integrated milk sterilization and cooling device includes a frame 1, a sterilization tank 2, a cooling tank 3, a constant temperature heating tank 4, and a water storage tank 5.

[0025] like Figure 1 , Figure 2 As shown, the frame 1 is horizontally set on the ground, the sterilization tank 2 is vertically set at one end of the frame 1, and the cooling tank 3 is vertically set at the other end of the frame 1.

[0026] like Figure 1 , Figure 2 As shown, a heating chamber 21 is formed inside the sterilization tank 2, and sterilization inlet 22 and sterilization outlet 23 connected to the heating chamber 21 are respectively provided on the lower and upper outer walls of the sterilization tank 2.

[0027] like Figure 1 , Figure 2 As shown, a cooling chamber 31 is formed inside the cooling barrel 3, and a cooling water inlet 32 ​​and a cooling water outlet 33 connected to the cooling chamber 31 are respectively provided on the upper and lower outer walls of the cooling barrel 3.

[0028] like Figure 1 , Figure 2 As shown, the constant temperature heating tank 4 is located between the sterilization tank 2 and the cooling tank 3, and is connected to the cooling water outlet 33 and the sterilization water inlet 22. The water storage tank 5 is located on the frame 1 and is connected to the sterilization water outlet 23.

[0029] When milk needs to be sterilized and cooled, the tap water pipe is directly connected to the cooling water inlet 32. At this time, cold water enters the cooling chamber 31 inside the cooling tank 3 from top to bottom, thereby cooling the milk inside the cooling tank 3. Meanwhile, the wastewater after use enters the constant temperature heating tank 4 along the cooling water outlet 33.

[0030] Since the wastewater contains a certain amount of heat after use, the constant temperature heating tank 4 can quickly heat the wastewater to the preset temperature, approximately 85°C. Then, the heated hot water is continuously introduced into the heating chamber 21 inside the sterilization tank 2 through the sterilization inlet 22 to heat and sterilize the milk inside the sterilization tank 2.

[0031] After use, the hot water is discharged through the sterilization outlet 23 into the storage tank 5 for storage, ensuring the supply of hot water and reducing the waste of thermal energy resources.

[0032] like Figure 2 , Figure 3 As shown, both the sterilization tank 2 and the cooling tank 3 are vertically rotatably connected to a stirring paddle 6, which includes a mounting tube 61, a mounting rod 62, and a stirring blade 7.

[0033] like Figure 3 As shown, the mounting tube 61 is vertically rotatably connected to the sterilization tank 2 or the cooling tank 3, and the mounting rod 62 is vertically slidably connected to the mounting tube 61. The outer wall of the mounting rod 62 is provided with a spline 63, and the inner wall of the mounting tube 61 is provided with a keyway 64.

[0034] like Figure 3 As shown, a guide post 65 is provided on the upper outer wall of the mounting rod 62, and a guide tube 66 located outside the mounting tube 61 is provided inside the sterilization tank 2 and the cooling tank 3. A guide groove 67 in annular shape and obliquely arranged is provided on the guide tube 66 to allow the guide post 65 to slide.

[0035] like Figure 3 As shown, the stirring plate 7 is disposed at the lower end of the mounting rod 62. The stirring plate 7 includes a base plate 71, a lower rod 72 and an upper rod 73.

[0036] like Figure 3 As shown, the base plate 71 is rotatably connected to the bottom wall of the sterilization tank 2 and the cooling tank 3, the lower rod 72 is rotatably connected to the four sides of the base plate 71, the upper rod 73 is rotatably connected to the four sides of the mounting rod 62 and is rotatably connected to the upper end of the lower rod 72, and the outer walls of the upper rod 73 and the lower rod 72 are provided with auxiliary blades 74.

[0037] When milk needs to be sterilized and cooled, the stirring paddle 6 can be used to fully stir the milk, thereby improving the efficiency of sterilization and cooling.

[0038] When the agitator 6 is working, the reducer drives the mounting tube 61 to rotate. At this time, under the cooperation of the spline 63 and the keyway 64, the mounting tube 61 drives the mounting rod 62 and the agitator 7 to rotate synchronously. During the rotation of the mounting rod 62, the mounting rod 62 drives the guide column 65 to move synchronously and slide in the guide groove 67 in the guide tube 66. At this time, the guide column 65 moves along the path of the guide groove 67, and the mounting rod 62 rotates and moves up and down reciprocally at the same time, so as to achieve thorough mixing of milk.

[0039] When the mounting rod 62 rotates, it drives the upper rod 73, the lower rod 72 and the base plate 71 to rotate synchronously. When the mounting rod 62 moves vertically back and forth, it will press down or stretch the upper rod 73 upward. Under the rotation of the upper rod 73 and the lower rod 72, the entire stirring blade 7 will extend and contract back and forth. With the cooperation of the auxiliary blade 74, the milk will be fully stirred.

[0040] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
