Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a sterilizing pot for food processing. Background Technology

[0002] In the food processing industry, autoclaves are crucial equipment for ensuring food safety. However, existing food processing autoclaves, as illustrated in patent document CN206851951U, generally suffer from numerous problems that urgently need to be addressed. Currently, most autoclave spray systems employ a fixed design, which inevitably creates blind spots during the sterilization process. Due to uneven sterilization, it is difficult to achieve commercial sterility requirements for low-acid foods. This not only directly affects the final quality of the food, potentially leading to unsatisfactory taste and color, but more seriously, it may also threaten food safety and pose potential risks to consumer health. Utility Model Content

[0003] In view of the problems and shortcomings of the existing technology, this utility model provides a sterilization pot for food processing.

[0004] The technical solution of this utility model is as follows:

[0005] A food processing sterilizer includes a sterilizing vessel, a heating tank, and a spray pipeline system, wherein the sterilizing vessel is equipped with a spray water inlet pipe.

[0006] Several rotating spray arms are evenly distributed at the bottom of the spray inlet pipe. Each rotating spray arm includes a branch pipe, a rotating support frame, and a spray pipe. The upper part of the branch pipe is connected to the spray inlet pipe, and the lower part is rotatably connected to the rotating support frame and connected to the rotating bracket. The spray pipe is configured as an annular pipe, located outside the rotating support frame, and connected to the rotating support frame and the branch pipe through an auxiliary pipe. An odd number of driving nozzles are evenly distributed around the outer circumference of the spray pipe, and several spray holes are evenly distributed at the bottom. The fluid jet direction of the driving nozzles is set at an acute angle to the radial direction of the annulus where the spray pipe is located, and the spray outlet of the spray holes is set downward.

[0007] The side wall of the branch pipe is provided with multiple connecting holes evenly distributed circumferentially to connect with the auxiliary pipe.

[0008] The angle between the outlet of the drive nozzle and the radius of the ring where the spray pipe is located is 40°-70°, preferably 50°.

[0009] Two to eight auxiliary pipes are evenly distributed around the perimeter of the spray pipe.

[0010] Preferably, four auxiliary pipes are evenly distributed around the circumference of the spray pipe.

[0011] The auxiliary pipe is arranged radially between the spray pipe and the rotating support.

[0012] Preferably, the heating tank is equipped with a spiral coil heat exchanger, which is installed inside the hot water tank and is made of stainless steel tube spirally coiled.

[0013] Furthermore, the outer diameter of the spiral coil heat exchanger is 50-80mm, and the spiral pitch is 80-120mm.

[0014] The beneficial effects of this utility model are:

[0015] The rotating spray arm design brings significant and multifaceted benefits to food sterilization. Compared to traditional fixed sprayers, its spray range is greatly expanded and more uniform, effectively eliminating blind spots. During the sterilization process, the all-around, dead-angle-free spray ensures that the sterilizing medium acts evenly on the food surface, greatly improving the uniformity of sterilization and effectively ensuring that food meets commercial sterility requirements, thus guaranteeing food quality and safety.

[0016] Meanwhile, the drive nozzle is set at a specific angle, cleverly utilizing the reaction force generated during fluid jetting to drive the spray pipe to rotate. This innovative design eliminates the need for an additional power unit, achieving efficient sterilization while reducing energy consumption during equipment operation and production costs. It combines practicality and economy, representing a significant advancement in food sterilization equipment. Attached Figure Description

[0024] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0025] Example

[0026] See Figure 1 and Figure 2 A food processing sterilizer mainly consists of a sterilizer 1, a heating tank 2, and a spray pipeline system 3. The sterilizer 1, as the main place for food sterilization, is equipped with a spray water inlet pipe 4 inside. Several rotating spray arms 5 are evenly distributed at the bottom of the spray water inlet pipe 4, preferably 3-6.

[0027] The rotating spray arm 5 is one of the key components of this sterilizer, see... Figures 3-5 It consists of a branch pipe 51, a rotating support frame 52, and a spray pipe 53. The branch pipe 51 is located at the upper part of the rotating spray arm 5, with its upper end connected to and communicating with the spray inlet pipe 4, and its lower end rotatably connected to the rotating support frame 52 via a bearing, while also communicating with the interior of the rotating support frame 52. Sealing elements are provided at both ends of the bearing. Multiple connecting holes are evenly distributed circumferentially on the side wall of the branch pipe 51. The function of these connecting holes is to allow the fluid in the branch pipe 51 to flow smoothly into the auxiliary pipe 54. Preferably, there are two or four connecting holes. Furthermore, a plug is provided at the bottom of the branch pipe 51.

[0028] The spray pipe 53 is annular and disposed outside the rotating support frame 52. It is connected to the rotating support frame 52 and the branch pipe 51 via an auxiliary pipe 54. Preferably, the auxiliary pipe 54 is disposed radially between the spray pipe 53 and the rotating support frame 52, and 2-8 pieces are evenly distributed around the circumference of the spray pipe 53, more preferably 4 pieces. The auxiliary pipe 54 serves to connect and conduct fluid, transporting the fluid in the branch pipe 51 to the spray pipe 53. Preferably, a plurality of spray holes 55 are also evenly distributed at the bottom of the auxiliary pipe 54.

[0029] See Figure 5 An odd number of drive nozzles 56 are evenly distributed around the outer circumference of the spray pipe 53, while several spray holes 55 are evenly distributed at the bottom. The fluid jetting direction of the drive nozzles 56 is set at an acute angle to the radial direction of the ring containing the spray pipe 53, and the angle between the outlet of the nozzles and the radial direction of the ring containing the spray pipe 53 is 40°-70°, preferably 50°. This arrangement allows the drive nozzles 56 to drive the spray pipe 53 to rotate on the rotating support frame 52 according to the principle of reaction force when jetting fluid. The spray outlets of the spray holes 55 are set downwards to facilitate downward spraying of food in the sterilizer 1.

[0030] A spiral coil heat exchanger 6 is installed on the heating tank 2, located inside the heating tank 2. The spiral coil heat exchanger is made of stainless steel tubes spirally wound, with an outer diameter of 50-80mm and a spiral spacing of 80-120mm. This structure increases the heat exchange area, allowing steam to exchange heat more fully with the hot water in the heating tank 2 when it passes through the spiral coil, thus increasing the temperature of the hot water and improving the steam utilization rate.

[0031] To further improve circulation efficiency, the vortex plate is provided with radial guide grooves. Preferably, the rotation direction of the spray arm is opposite to the tilt direction of the guide grooves on the bottom vortex plate.

[0032] Working Principle: During the sterilization process, hot water enters the branch pipe 51 of the rotating spray arm 5 from the spray inlet pipe 4, then flows into the auxiliary pipe 54 through the connecting hole on the side wall of the branch pipe 51, and then enters the spray pipe 53 through the auxiliary pipe 54. The drive nozzle 56 on the spray pipe 53 sprays fluid. Since the spray direction forms an acute angle with the radial direction of the ring, according to the principle of reaction force, the spray pipe 53 will start to rotate relative to the branch pipe 51 with the rotating support frame 52. At the same time, hot water is sprayed downward from the spray hole 55, spraying and sterilizing the food in the sterilizer 1 in an all-round and uniform manner. The spiral coil heat exchanger in the heating tank 2 conducts efficient heat exchange between steam and hot water, raising the temperature of the hot water, thereby ensuring that the sterilizer can maintain a suitable sterilization temperature and meet the requirements of precise food sterilization.

[0033] The above description represents a preferred embodiment of the present invention. However, the present invention is not limited to the above-described embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, all variations, equivalent substitutions, and improvements made without departing from the concept of the present invention should be included within the protection scope of the present invention.
