Description

Technical Field

[0001] This utility model belongs to the field of modified milk powder processing technology, and specifically relates to a sterilization device for modified milk powder processing. Background Technology

[0002] Modified milk powder, as an important infant food and daily beverage, is widely used for nutritional supplementation of children and adults. In order to ensure its safety and nutritional value, the production process of modified milk powder must be strictly controlled to avoid contamination by pathogenic microorganisms and bacteria. The sterilization process plays a crucial role in milk powder processing, which can effectively kill or inhibit microorganisms such as bacteria, molds, and yeasts that may be present in milk powder, ensuring the safety of the final product, extending its shelf life, and maintaining the stability of its nutritional components.

[0003] A prior art patent, CN221207931U, describes a processing device for modified milk powder. This patent includes an outer shell, with an electromechanical box fixedly connected to its upper surface. A motor is fixedly connected to the inner top wall of the electromechanical box, and an insulation shell is fixedly connected to the inner bottom wall of the outer shell. The upper surface of the insulation shell is connected to the inner top wall of the outer shell, and a bearing is fixedly embedded in the inner top wall of the outer shell. This device uses a rotating plate to uniformly stir the milk powder inside the insulation shell, effectively preventing the milk powder from accumulating inside and failing to be fully sterilized, thus improving the sterilization efficiency of the device. However, in practical use, the following shortcomings still exist: From a practical standpoint, the rotating plate of this device is fixed in the horizontal direction, only able to stir the modified milk powder on the same horizontal plane. This limits the stirring range, resulting in uneven distribution of the milk powder at different levels in the sterilization tank. Some milk powder may remain at the bottom or top of the equipment, failing to receive sufficient stirring and heating, thus reducing the sterilization effect.

[0004] Therefore, a sterilization device for processing modified milk powder is needed to solve the problem in the existing technology where the stirring blades can only stir the modified milk powder on the same horizontal plane, resulting in uneven distribution of milk powder in different layers in the sterilization tank. Utility Model Content

[0005] The purpose of this invention is to provide a sterilization device for processing formulated milk powder, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sterilization device for processing modified milk powder, comprising a sterilization tank, a plurality of support columns fixedly connected to the bottom of the sterilization tank, a conveying pipe fixedly connected to the top of the sterilization tank, a feeding hopper fixedly connected to the top of the conveying pipe, a dust cover detachably connected to the top of the feeding hopper, a plurality of evenly distributed electric heating rods fixedly connected to the inner wall of the sterilization tank, a control panel corresponding to the electric heating rods installed at the front end of the sterilization tank, a stirring mechanism provided inside the sterilization tank, an observation window opened at the front end of the sterilization tank, and a discharge pipe fixedly connected to the bottom of the sterilization tank, with a solenoid valve installed inside the discharge pipe.

[0007] It should be noted in the plan that the sterilization tank has an internal interlayer with an insulation board installed.

[0008] It is worth noting that shock-absorbing pads are fixedly connected to the bottom of each of the aforementioned support columns.

[0009] It should be further noted that the dust cover is threadedly connected to the top of the feeding hopper.

[0010] In a preferred embodiment, the stirring mechanism includes a convex frame fixedly connected to the top of the sterilization tank. A servo motor is fixedly connected to the top of the convex frame. A spline sleeve is fixedly connected to the output end of the servo motor through the convex frame. A spline shaft is rotatably mounted on the top of the sterilization tank. Multiple sleeves are fixedly connected to the outer wall of the spline shaft near the bottom. Multiple stirring blades are fixedly connected to the outer walls of the multiple sleeves. A cylinder is fixedly connected to the outer wall of the spline shaft near the top. An arc-shaped groove is formed on the outer wall of the cylinder. A guide column is fixedly connected to the inner wall of one side of the convex frame.

[0011] In a preferred embodiment, the top of the spline shaft is slidably connected to the inner wall of the spline sleeve.

[0012] In a preferred embodiment, the guide post slides on the inner wall of the arc-shaped groove.

[0013] Compared with the prior art, the sterilization device for processing modified milk powder provided by this utility model has at least the following beneficial effects:

[0014] (1) By setting up a stirring mechanism, while sterilizing at high temperature, the servo motor is turned on to drive the spline sleeve to rotate, so that the spline sleeve drives the spline shaft to rotate. Multiple sets of stirring blades stir and mix the modified milk powder inside the sterilization tank. With the cooperation of the guide column and the arc groove, the cylinder moves back and forth in the vertical direction while rotating, so that the spline shaft drives multiple sets of stirring blades to move back and forth in the vertical direction while rotating. By introducing vertical movement, the milk powder in each layer can be heated more evenly, reducing uneven heat distribution, thereby avoiding the milk powder in some areas from failing to reach the predetermined sterilization temperature, and ensuring that the sterilization effect of the entire batch of milk powder is consistent.

[0015] (2) By setting a dust cover on the top of the feeding hopper, the dust cover can effectively block external pollutants such as dust and impurities in the air from entering the feeding hopper, thereby maintaining the cleanliness of the milk powder, preventing pollutants from coming into contact with the milk powder, and ensuring hygiene and product quality during the production process.

Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4This utility model provides a sterilization device for processing modified milk powder, including a sterilization tank 1, a plurality of support columns 2 fixedly connected to the bottom of the sterilization tank 1, a conveying pipe 3 fixedly connected to the top of the sterilization tank 1, a feeding hopper 4 fixedly connected to the top of the conveying pipe 3, a dust cover 5 detachably connected to the top of the feeding hopper 4, a plurality of evenly distributed electric heating rods 6 fixedly connected to the inner wall of the sterilization tank 1, a control panel 7 corresponding to the electric heating rods 6 installed at the front end of the sterilization tank 1, a stirring mechanism 8 provided inside the sterilization tank 1, an observation window 9 opened at the front end of the sterilization tank 1, and a discharge pipe 10 fixedly connected to the bottom of the sterilization tank 1, with a solenoid valve 11 installed inside the discharge pipe 10.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the sterilization tank 1 has an internal insulation board installed. The insulation board can effectively reduce heat loss and maintain a stable internal temperature in the sterilization tank 1, ensuring uniform and efficient heating when processing milk powder. This helps to improve the overall sterilization efficiency and ensures that the milk powder is sterilized within the specified time. At the same time, since the temperature in the production environment may be unstable, the insulation board can isolate external temperature changes, ensuring that the internal temperature of the sterilization tank 1 changes less, thereby improving the stability and consistency of milk powder processing.

[0024] Further as Figure 1 and Figure 2 As shown, it is worth noting that the bottom of each of the multiple support columns 2 is fixedly connected with a shock-absorbing pad. During the operation of the equipment, especially during the stirring and heating process, there may be significant vibrations. The shock-absorbing pad can effectively absorb and reduce these vibrations, prevent the vibrations from affecting the equipment, and avoid damage to the equipment or a decrease in precision.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth noting that the dust cover 5 is threaded to the top of the feeding hopper 4. The threaded connection ensures the seal between the dust cover 5 and the feeding hopper 4, preventing external impurities and dust from entering the equipment, thereby ensuring the hygiene and safety of the raw materials during the milk powder processing. At the same time, the threaded connection allows the dust cover 5 to be easily disassembled and installed, facilitating regular cleaning or maintenance. When it is necessary to inspect or clean the feeding hopper 4, simply rotate the dust cover 5.

[0026] As can be seen from the above working process, by setting a dust cover 5 on the top of the feeding hopper 4, the dust cover 5 can effectively block external pollutants such as dust and impurities in the air from entering the feeding hopper 4, thereby maintaining the cleanliness of the milk powder, preventing pollutants from contacting the milk powder, and ensuring hygiene and product quality during the production process.

[0027] Further as Figure 4As shown, it is worth noting that the stirring mechanism 8 includes a convex frame 801 fixedly connected to the top of the sterilization tank 1. A servo motor 802 is fixedly connected to the top of the convex frame 801. A spline sleeve 803 is fixedly connected to the output end of the servo motor 802 through the convex frame 801. A spline shaft 804 is rotatably mounted on the top of the sterilization tank 1. Multiple sleeves 805 are fixedly connected to the outer wall of the spline shaft 804 near the bottom. Multiple stirring blades 806 are fixedly connected to the outer wall of each sleeve 805. A cylinder 807 is fixedly connected to the outer wall of the spline shaft 804 near the top. An arc groove 808 is opened on the outer wall of the cylinder 807. A guide post 809 is fixedly connected to the inner wall of one side of the convex frame 801. By setting the stirring mechanism 8 and introducing vertical movement, the milk powder in each layer can be heated more evenly, reducing uneven heat distribution. This avoids the milk powder in some areas failing to reach the predetermined sterilization temperature, ensuring that the sterilization effect of the entire batch of milk powder is consistent.

[0028] Further as Figure 4 As shown, it is worth noting that the top of the spline shaft 804 is slidably connected to the inner wall of the spline sleeve 803, and the spline sleeve 803 ensures that the spline shaft 804 does not affect its own rotation when sliding up and down.

[0029] Further as Figure 4 As shown, it is worth noting that the guide post 809 slides on the inner wall of the arc groove 808, so that the guide post 809 can guide the movement of the cylinder 807, causing the cylinder 807 to reciprocate in the vertical direction while rotating.

[0030] This solution has the following working process: In actual use, milk powder raw materials enter the sterilization tank 1 through the feeding hopper 4. After feeding is completed, the dust cover 5 is rotated and closed. After the raw materials enter the sterilization tank 1, the operator operates the heating rod 6 through the control panel 7. The heating rod 6 heats the internal temperature of the tank, heating the milk powder to an appropriate temperature for sterilization. At the same time, the servo motor 802 is turned on to drive the spline sleeve 803 to rotate, which in turn drives the spline shaft 804 to rotate. Multiple sets of stirring blades 806 stir and mix the prepared milk powder inside the sterilization tank 1. With the cooperation of the guide column 809 and the arc groove 808, the cylinder 807 moves back and forth in the vertical direction while rotating, so that the spline shaft 804 drives the multiple sets of stirring blades 806 to move back and forth in the vertical direction while rotating, making the milk powder in each layer more evenly heated. After sterilization, the sterilized milk powder is discharged through the discharge pipe 10 at the bottom.

[0031] In summary: By installing a dust cover 5 on the top of the feeding hopper 4, the dust cover 5 can effectively block external pollutants such as dust and impurities in the air from entering the feeding hopper 4, thereby maintaining the cleanliness of the milk powder, preventing pollutants from contacting the milk powder, and ensuring hygiene and product quality during the production process; by setting up a stirring mechanism 8, vertical movement is introduced, which can make the milk powder in each layer more evenly heated, reducing uneven heat distribution, thereby avoiding the milk powder in some areas failing to reach the predetermined sterilization temperature, and ensuring that the sterilization effect of the entire batch of milk powder is consistent.
