Abstract
Description
Technical Field
[0001] This utility model relates to the field of sterilization equipment technology, and in particular to a raw material sterilization device for cheese stick production. Background Technology
[0002] Cheese sticks are chilled desserts made primarily from whole milk and cheese slices, characterized by a rich blend of milk and condensed milk flavors. In 2004, the French company, Somveet, launched cheese sticks with handles specifically for the Chinese market, adjusting the fermentation process to create a sweet and savory flavor that suits the preferences of Chinese consumers.
[0003] In the prior art, to facilitate the consumption of cheese sticks, cheese is generally molded and attached to a plastic handle. The main material of the plastic handle is food-grade polypropylene plastic. Before being processed into cheese handles, food-grade polypropylene plastic needs to be sterilized. The main process includes melting the polypropylene plastic and mixing it with a sterilizing agent. However, in the prior art, the melting of polypropylene plastic and the mixing of the sterilizing agent are carried out separately. The melted polypropylene plastic needs to be transported and transferred. The process of transporting and transferring polypropylene plastic can easily lead to waste of raw materials, and the melted polypropylene plastic is prone to re-solidification due to temperature drop, which is not conducive to the addition of sterilizing agents.
[0004] Therefore, it is necessary to invent a raw material sterilization device for cheese stick production to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a raw material sterilization device for cheese stick production, 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 raw material sterilization device for cheese stick production, comprising a processing tank, an end cap fixedly provided at the top of the processing tank, a feed pipe fixedly provided at the middle of the lower surface of the end cap, an overflow pipe fixedly provided on the outer side of the feed pipe, a connecting groove provided between the bottom end of the feed pipe and the overflow pipe, a plurality of overflow grooves surrounding the top of the outer wall of the overflow pipe, a plurality of guide rods surrounding the top of the outer wall of the overflow pipe, the guide rods being configured as a "√" shape, and the plurality of guide rods being staggered with the plurality of overflow grooves, a guide cover fixedly provided on the outer side of the plurality of guide rods, and the guide cover being fixedly provided on the lower surface of the end cap, a fixing cover fixedly provided at the top of the overflow pipe, and the fixing cover being provided on the outer side of the feed pipe, a feeding pipe fixedly provided on the upper surface of the end cap, and the bottom end of the feeding pipe being provided between the guide cover and the fixing cover, and a spiral guide plate surrounding the outer side of the overflow pipe.

[0009] Preferably, a stirring rod is fixedly provided on the outer side of the rotating shaft, and a stirring motor is fixedly provided at the bottom end of the processing tank. The output shaft of the stirring motor is connected to the bottom end of the stirring rod.
[0010] Preferably, a jacket is fixedly provided on the outside of the processing tank, and a connecting pipe is fixedly provided at both ends of the jacket.
[0011] Preferably, the top center of the end cap is fixedly provided with a feed inlet, and the feed inlet is connected to the feed pipe.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model sets up a processing tank, a feed pipe, an overflow pipe, and a connecting trough. The feed pipe, overflow pipe, and connecting trough form a communicating vessel structure. Both the feed pipe and the overflow pipe are equipped with heaters. When sterilizing the polypropylene raw material for cheese stick handles, the polypropylene raw material first enters the feed pipe and the overflow pipe. The feed pipe can heat the polypropylene raw material to melt it, while the overflow pipe can maintain the high temperature of the melted polypropylene raw material to achieve high-temperature sterilization of the polypropylene raw material. Furthermore, as more polypropylene raw material is injected, the polypropylene raw material that has completed high-temperature sterilization can be discharged through the overflow trough at the top of the overflow pipe to achieve continuous sterilization of the polypropylene raw material.
[0014] 2. This utility model, by setting guide rods, a guide cover, and a guide plate, allows the melted polypropylene raw material to pass through multiple guide rods after being discharged through an overflow tank. Meanwhile, the bactericide can be added above the guide rods via a feeding pipe. As the polypropylene raw material passes through the guide rods, it mixes with the bactericide, achieving both high-temperature sterilization and mixing. Furthermore, the mixed polypropylene raw material and bactericide flow along the spiral guide plate, colliding with each other during the spiral motion, thus enhancing the mixing effect and improving the sterilization effect of the polypropylene raw material for cheese stick handles.

[0024] Multiple heaters 12 are arranged around the inner walls of both the feed pipe 3 and the overflow pipe 4. It should be noted that the heaters 12 are electric heating tubes in the prior art, and their surfaces are coated with a protective coating to prevent the polypropylene raw materials from sticking together. Furthermore, the heaters 12 inside the feed pipe 3 have a larger power, which can heat the polypropylene raw materials inside the feed pipe 3 to a molten state. The heaters 12 inside the overflow pipe 4 have a relatively smaller power, which can keep the molten polypropylene raw materials inside the overflow pipe 4 at a high temperature.
[0025] The bottom of the treatment tank 1 is rotatably equipped with a rotating shaft 13. The top of the rotating shaft 13 is fixedly equipped with a distribution plate 14. The outer wall of the distribution plate 14 is fixedly equipped with a discharge pipe 15, and the discharge pipe 15 is designed with an inclined structure. The distribution plate 14 drives the material after the polypropylene raw material and the bactericide are mixed to rotate. Under the action of centrifugal force, the mixture passes through the discharge pipe 15 and enters the treatment tank 1. It should be noted that the rotating shaft 13 and the treatment tank 1 are connected by a sealed bearing. It adopts the existing structure in the prior art, which can avoid the device leakage caused by the setting of the rotating shaft 13.
[0026] A stirring rod 16 is fixedly provided on the outer side of the rotating shaft 13, and a stirring motor 17 is fixedly provided at the bottom of the processing tank 1.

[0027] A jacket 18 is fixedly provided on the outside of the treatment tank 1. A connecting pipe 19 is fixedly provided at both ends of the jacket 18.

The inlet 20 can be connected to the raw material pump to realize the injection of polypropylene raw material. It should be noted that the processing tank 1 is set as the existing structure in the prior art, and its surface is provided with accessories such as a discharge port, thermometer, and pressure gauge.
[0029] Working principle of this utility model:
[0030] When using this device, the polypropylene raw material to be processed is injected into the feed pipe 3 through the feed inlet 20. The polypropylene raw material in the feed pipe 3 enters the overflow pipe 4 through the connecting groove 5, filling the communicating vessel structure composed of the feed pipe 3, the overflow pipe 4 and the connecting groove 5. As more polypropylene raw material is injected, the material height in the overflow pipe 4 rises. At this time, the polypropylene raw material can flow out of the overflow pipe 4 through the overflow groove 6. During this process, two sets of heaters 12 heat the polypropylene raw material in the feed pipe 3 and the overflow pipe 4 respectively. The polypropylene raw material is heated to melt in the feed pipe 3 and then kept in a high-temperature melted state in the overflow pipe 4. By controlling the injection speed of the polypropylene raw material, the polypropylene raw material stays in the overflow pipe 4. During this process, the polypropylene raw material can be sterilized at high temperature in the feed pipe 3 and the overflow pipe 4.
[0031] After sterilization, the polypropylene raw material flows out of the overflow pipe 4 through the overflow tank 6. During this process, the polypropylene raw material passes through the gaps between multiple guide rods 7. At this time, the sterilizing agent is added into the guide hood 8 through the feeding pipe 10. The sterilizing agent falls down guided by the guide rods 7. When the polypropylene raw material passes through the guide rods 7, it can mix with the sterilizing agent. The mixed material falls onto the guide plate 11 and moves downward in a spiral motion along the guide plate 11. During the movement, the polypropylene raw material collides with the sterilizing agent, accelerating the mixing of the polypropylene raw material and the sterilizing agent. After the mixed material moves to the bottom of the guide plate 11, it can... The mixture falls into the distribution plate 14. At this time, the stirring motor 17 drives the distribution plate 14 to rotate through the rotating shaft 13. The distribution plate 14 drives the mixture to rotate. Under the action of centrifugal force, the mixture passes through the discharge pipe 15 and enters the processing tank 1. Then the stirring rod 16 can stir the mixture to ensure that the polypropylene raw material and the bactericide are completely mixed and to avoid the polypropylene raw material from hardening. After the polypropylene raw material is mixed with the bactericide, it can be discharged through the discharge port at the bottom of the processing tank 1. The discharged polypropylene raw material can be directly guided to the injection molding machine for the injection molding of cheese stick handles.
[0032] It should be noted that the polypropylene raw material involved in this embodiment is a powder or granular structure. The polypropylene raw material in the powder or granular structure can be rapidly melted and sterilized at high temperature inside the device. The bactericide involved in this embodiment can be one of a variety of PP antibacterial agents, polypropylene antibacterial agents, etc., and no restrictions are imposed on it as long as it meets food-grade requirements and does not affect the normal implementation of this embodiment.
[0033] It should be further noted that the processing tank 1 in this embodiment adopts the corresponding structure in the prior art, and is equipped with a discharge port and a discharge pump to facilitate the discharge of materials.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
