Description

Technical Field

[0001] This utility model relates to the field of dairy product heating technology, specifically to a preheating device for dairy product production. Background Technology

[0002] The main function of a preheating device for dairy product production is to heat dairy products (such as milk, yogurt, cheese, etc.) to a suitable temperature to facilitate subsequent processing. The suitable temperature can activate enzymes in dairy products, promote chemical reactions, and also help to sterilize and inhibit the growth of harmful microorganisms. Through preheating, the viscosity of dairy products decreases and their fluidity increases, making the subsequent processing process smoother and thus improving production efficiency. Preheating can ensure that dairy products maintain stable quality during processing and avoid quality degradation caused by temperature changes. The preheating device for dairy product production is a key piece of equipment to ensure that dairy products are processed at a suitable temperature, with stable quality, and are safe and hygienic.

[0003] Chinese Patent Publication No. CN216219928U, entitled "A Dairy Product Preheating Device," includes a housing. A motor is fixedly connected to the top of the housing, and a telescopic rod is fixedly connected to the output end of the motor. The telescopic rod passes through the housing and is rotatably connected to it. A reciprocating screw is fixedly connected to the bottom of the telescopic rod. A limiting block is sleeved on the outer wall of the reciprocating screw, and the limiting block is fixedly connected to the inner wall of the housing. A rotating rod is fixedly connected to the bottom of the reciprocating screw, and multiple stirring rods are fixedly connected to the outer wall of the rotating rod. This invention preheats raw materials at different levels to ensure uniform preheating; it also depressurizes the housing to prevent excessive internal pressure and potential hazards, and allows for a sealed housing, minimizing heat loss.

[0004] The shortcomings of the above solution are as follows: Although the above solution can heat the raw materials, heating is only achieved through stirring, which may result in uneven heating. Since stirring may not be able to completely cover all areas, some parts may overheat due to direct contact with the heating source, leading to damage to product quality. During the stirring process, the materials in different locations may generate temperature gradients due to differences in stirring speed, fluid dynamics, and heat conduction, resulting in the technical problem of uneven heating. Utility Model Content

[0005] The purpose of this invention is to provide a preheating device for dairy product production, which solves the technical problems of uneven heating caused by heating by stirring alone during use, the inability of stirring to completely cover all areas and the potential for localized overheating in some areas due to direct contact with the heating source, resulting in damage to product quality, and the potential for uneven heating due to temperature gradients in materials at different locations during stirring due to differences in stirring speed, fluid dynamics and heat conduction.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A preheating device for dairy product production includes a preheating cylinder;

[0008] A temperature detection device is connected to the preheating cylinder, a connecting ring is connected to the preheating cylinder, a heating box is connected to the bottom of the preheating cylinder, a mounting plate is connected to the top of the heating box, a through hole is opened in the middle of the mounting plate, the preheating cylinder is placed in the through hole, the bottom of the preheating cylinder is connected to the heating box, an electric sliding rod is connected between the connecting ring and the mounting plate, a sliding groove is provided on the mounting plate, and the electric sliding rod is slidably connected in the sliding groove;

[0009] The top of the preheating cylinder is detachably connected to a top cover, and a rotating motor is connected to the top cover. A stirring mechanism is connected between the rotating motor and the preheating cylinder. The stirring mechanism includes a rotating shaft and multiple rotating plates. Multiple connecting shafts are connected to the rotating shaft, and the multiple rotating plates are all connected to the end of the connecting shaft away from the rotating shaft.

[0010] As a further embodiment of this utility model: the heating box is provided with an annular heating element.

[0011] As a further embodiment of this utility model, the electric slide rod and the connecting ring are detachably connected by a connecting bolt.

[0012] As a further embodiment of this utility model, a rotating handle is connected to the mounting plate.

[0013] As a further embodiment of this utility model: the rotating end of the rotating motor is connected to a flat key, and the rotating shaft is connected to the rotating end of the rotating motor via the flat key.

[0014] As a further embodiment of this utility model, each of the rotating plates is provided with multiple elongated holes.

[0015] The beneficial effects of this utility model are:

[0016] 1. The electric slide bar of this utility model slides within the slide groove. The movement of the electric slide bar drives the connecting ring to rotate. The connecting ring rotates synchronously with the preheating cylinder, which facilitates uniform heating. Alternatively, the connecting ring can be moved by the handle, which in turn drives the preheating cylinder to rotate. The rotation of the preheating cylinder ensures that the dairy products are heated evenly during the preheating process. Synchronous rotation ensures that each batch of products achieves the same preheating effect. The heating box is equipped with a ring heating element, which can provide a rapid and uniform heating effect because heat can be transferred from multiple directions, reducing heat loss and heating time.

[0017] 2. In this utility model, the rotating shaft is connected to the rotating end of the rotating motor via a flat key, which facilitates the disassembly and reassembly of the rotating motor and the rotating shaft. When the rotating motor is started, the dairy products are stirred by the stirring mechanism to ensure that the dairy products are heated evenly during the preheating process. The rotation of the rotating motor is transmitted to the rotating shaft via the flat key. The rotating shaft drives the rotating plate through the connecting shaft. The rotating plate rotates inside the preheating cylinder. The multiple elongated holes on the rotating plate increase the flow path of the dairy products in the preheating cylinder, allowing the dairy products to flow more smoothly during the preheating process and reducing flow resistance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-2As shown, a preheating device for dairy product production includes a preheating cylinder 5, a temperature detection device connected to the preheating cylinder 5, a connecting ring 4 connected to the preheating cylinder 5, a heating box 2 connected to the bottom of the preheating cylinder 5, an annular heating element inside the heating box 2, a mounting plate 1 connected to the top of the heating box 2, a through hole in the middle of the mounting plate 1, the preheating cylinder 5 being disposed in the through hole, the bottom of the preheating cylinder 5 being connected to the heating box 2, an electric sliding rod 7 connected between the connecting ring 4 and the mounting plate 1, a connecting bolt 6 detachably connected between the electric sliding rod 7 and the connecting ring 4, a sliding groove 3 provided on the mounting plate 1, the electric sliding rod 7 being slidably connected in the sliding groove 3, and a rotating handle 14 connected to the mounting plate 1.

[0024] The top of the preheating cylinder 5 is detachably connected to a top cover 12. A rotating motor 13 is connected to the top cover 12. A stirring mechanism is connected between the rotating motor 13 and the preheating cylinder 5. The stirring mechanism includes a rotating shaft 11 and multiple rotating plates 9. A flat key is connected to the rotating end of the rotating motor 13. The rotating shaft 11 is connected to the rotating end of the rotating motor 13 via a flat key. Multiple connecting shafts 8 are connected to the rotating shaft 11. The multiple rotating plates 9 are all connected to the end of the connecting shaft 8 away from the rotating shaft 11. Each rotating plate 9 has multiple elongated holes 10.

[0025] The working principle of this utility model is as follows: Dairy products first enter the preheating cylinder 5, and the top cover 12 is placed on the preheating cylinder 5. The bottom of the preheating cylinder 5 is connected to the heating box 2. The heating box 2 is equipped with annular heating elements, which heat the preheating cylinder 5. A temperature detection device monitors the temperature inside the cylinder in real time to ensure that the dairy products are preheated at a suitable temperature. The electric slide rod 7 slides in the slide groove 3. The movement of the electric slide rod 7 drives the connecting ring 4 to rotate. The connecting ring 4 rotates synchronously with the preheating cylinder 5 to facilitate uniform heating. Alternatively, the connecting ring 4 can be moved by the handle 14, which drives the preheating cylinder 5 to rotate. The rotation of the preheating cylinder 5 ensures that the dairy products are heated evenly during the preheating process. Then, the rotating motor 13 drives the agitator. The mixing mechanism has a rotating shaft 11 connected to the rotating end of the rotating motor 13 via a flat key, facilitating disassembly between the rotating motor 13 and the rotating shaft 11. When the rotating motor 13 is started, the mixing mechanism stirs the dairy products, ensuring that the dairy products are heated evenly during the preheating process. The rotation of the rotating motor 13 is transmitted to the rotating shaft 11 via the flat key. The rotating shaft 11 drives the rotating plate 9 via the connecting shaft 8. The rotating plate 9 rotates inside the preheating cylinder 5. Multiple elongated holes 10 are provided on the rotating plate 9. The design of the elongated holes 10 increases the flow path of the dairy products in the preheating cylinder 5, allowing the dairy products to flow more smoothly during the preheating process, reducing flow resistance, and stirring and mixing the dairy products, ensuring that the dairy products are heated evenly during the preheating process.

[0026] The preheating device heats the preheating cylinder 5 through the heating box 2, controls the position of the preheating cylinder 5 with the electric slide bar 7, and stirs and preheats the dairy products by rotating the motor 13 and the stirring mechanism, thereby achieving uniform preheating and mixing of the dairy products.
