Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a sterilization device for donkey meat production. Background Technology

[0002] The main purpose of sterilization in donkey meat production is to kill or eliminate microorganisms, including bacteria and viruses, in the meat to prevent spoilage, extend shelf life, and ensure consumer safety. Commonly used steam sterilizers utilize the high temperature and pressure of steam to sterilize donkey meat products. The uniform heating ensures that each package of donkey meat products receives thorough sterilization, achieving a commercially sterile state.

[0003] Utility model patent CN220274846U discloses a high-temperature steam sterilizer, including a pot body with a lid installed on the front side. A steam inlet pipe and a drain pipe are fixedly connected to the top and bottom of the pot body, respectively. A spiral-shaped steam guide pipe is arranged inside the pot wall, communicating with the steam inlet pipe. Steam injection holes arranged spirally along the steam guide pipe are opened on the inner wall of the pot body, communicating with the steam guide pipe. The advantages are: the spiral-shaped steam guide pipe inside the pot wall and the multiple spirally arranged steam injection holes on the inner wall of the pot body, with a rubber layer communicating with the steam guide pipe, allow steam to be evenly ejected within the pot body, ensuring uniform heating. Furthermore, the pot body includes a supporting rotation mechanism and a material holding mechanism. The supporting rotation mechanism drives the material holding mechanism to rotate, causing the food to continuously tumble within the pot body, further improving heating uniformity and ensuring sterilization effectiveness.

[0004] However, when the above-mentioned patent is used, the steam ejected from the steam nozzle can only be ejected in a fixed direction, so the area and angle of the steam injection cannot be changed. This results in insufficient uniformity of food heating. The food surface directly sprayed with steam will heat up faster than the food surface that is not directly sprayed with steam, leading to local overheating or underheating of the food, which in turn affects the taste and quality of the food. Utility Model Content

[0005] The purpose of this invention is to provide a sterilization device for donkey meat production, which solves the problems of insufficient uniform heating of food due to the inability to change the angle of steam injection in the pot and increase the steam injection area, resulting in local overheating or underheating of food, and thus affecting the quality of food.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A sterilization device for donkey meat production includes a horizontal cylindrical pot body, open on the left and closed on the right, with a drain pipe installed at the bottom. A rotating steam jet device is installed inside the pot body, and a drive device for rotating the steam jet device is installed at the right end. A material cylinder is installed in the middle of the pot body, and a pot lid is hinged and sealed to the left end of the pot body. The rotating steam jet device includes a steam inlet pipe, a turntable, branch pipes, a steam jet head, and a driven gear. The steam inlet pipe is located at the axial position on the right side of the pot body and is installed to the pot body via a bearing seat. The right end of the steam inlet pipe is outside the pot body, and the left end is inside the pot body. The left end is fixedly connected to a hollow turntable. Multiple L-shaped branch pipes are connected to the outer circumference of the turntable. The vessel is equipped with multiple equidistant steam nozzles. A driven gear is fixed on the steam inlet pipe on the outer side of the vessel body. The driven gear is driven by a drive device. Multiple equidistant corrugated grooves are distributed on the inner circumference of the vessel body. The rotating steam injection device includes a split nozzle, a fixed pipe, a fixed nozzle, a rotating pipe, a rotating nozzle, and a guide roller. The split nozzle is radially fixed on the branch pipe. A fixed pipe is provided on one side of the split nozzle, and a fixed nozzle is connected to the end of the fixed pipe. A rotating pipe is connected to the other side, and a rotating nozzle is fixed to the end of the rotating pipe. The steam injection direction of the fixed nozzle and the rotating nozzle is towards the material cylinder. A guide roller is fixed on the side of the rotating nozzle facing the inner wall of the vessel body. The end of the guide roller is slidably connected along the corrugated groove.

[0008] Preferably, the driving device includes a motor fixedly mounted to the pot body, and a driving gear is fixedly mounted on the output end of the motor, the driving gear meshing with the driven gear.

[0009] Preferably, a support roller is installed at the end of the branch pipe, and the outer circumferential surface of the support roller contacts the inner circumferential wall of the pot body.

[0012] Preferably, the left side of the material cylinder has balls distributed around its circumference, and the balls are in contact with the material cylinder cover.

[0013] Preferably, a plurality of spring posts are installed between the material cylinder cover and the pot cover.

[0014] Preferably, a support base is fixed to the bottom of the pot body.

[0015] This utility model has the following beneficial effects:

[0016] The rotary jet device can drive the pot to rotate in a circular motion, causing the fixed nozzle to rotate and spray steam in a circular motion, which heats the food in the material cylinder evenly. The rotary nozzle can rotate along the rotating tube and slide along the corrugated groove through the guide roller, so that the rotary nozzle can rotate in a circular motion in the pot and also reciprocate along the rotating tube. By changing the spray angle, the steam spray area is further increased, making the food heat more even and ensuring that the taste and quality of the food are improved. Attached Figure Description

[0031] like Figure 1-11As shown, in this embodiment, a sterilization device for donkey meat production includes a horizontal cylindrical pot body 1. The pot body 1 is open on the left and closed on the right. A drain pipe 11 is installed at the bottom to allow steam inside the pot body 1 to liquefy, collect, and be discharged at the bottom. A rotating steam injection device 2 is installed inside the pot body 1, capable of rotating 360° around the axis of the pot body 1 to uniformly inject steam. A drive device 3 is installed at the right end to drive the rotating steam injection device 2 to rotate. A material cylinder 4 is installed in the middle of the pot body 1 for holding the food to be sterilized. A pot lid 5 is hinged to the left end of the pot body 1 and sealed to prevent the contents of the pot body 1 from entering the pot. Steam leakage is prevented by the rotary steam injection device 2, which includes a steam inlet pipe 21, a turntable 22, branch pipes 23, a steam injection head 24, and a driven gear 25. The steam inlet pipe 21 is located at the axial position on the right side of the pot body 1 and is installed with the pot body 1 through a bearing seat so that the steam inlet pipe 21 can be driven to rotate by the drive device 3. The right end of the steam inlet pipe 21 is located outside the pot body 1 for connecting to an external steam heater, and the left end is located inside the pot body 1 for introducing external steam into the pot body 1. The left end of the steam inlet pipe 21 is fixedly connected to a hollow turntable 22. Multiple L-shaped branch pipes 23 are connected to the outer circumference of the turntable 22. The disc 22 disperses steam into the branch pipe 23 and drives the branch pipe 23 to rotate synchronously. Multiple equidistant steam nozzles 24 are installed on the branch pipe 23 for injecting steam. A driven gear 25 is fixed on the steam inlet pipe 21 on the outer side of the boiler body 1. The driven gear 25 is driven by the drive device 3 through a gear connection. Multiple equidistant corrugated grooves 12 are distributed on the inner circumference of the boiler body 1. The rotating steam injection device 2 includes a diversion nozzle 241, a fixed pipe 242, a fixed nozzle 243, a rotating pipe 244, a rotating nozzle 245, and a guide roller 246. The diversion nozzle 241 has a diameter... A fixed pipe 242 is provided on one side of the diversion nozzle 241, which is fixed to the branch pipe 23. A fixed nozzle 243 is connected to the end of the fixed pipe 242, allowing the fixed nozzle 243 to rotate around the circumference of the pot body 1 and spray high-temperature steam. A rotating pipe 244 is connected to the other side, and a rotating nozzle 245 is fixed to the end of the rotating pipe 244. The steam spray direction of both the fixed nozzle 243 and the rotating nozzle 245 is towards the material cylinder 4. A guide roller 246 is fixed to the side of the rotating nozzle 245 facing the inner wall of the pot body 1, and the end of the guide roller 246 is slidably connected within the corrugated groove 12. This allows the rotating nozzle 245 to rotate circumferentially within the pot body 1 while also reciprocating along the rotating pipe 244, changing the spray angle to further increase the steam spray area, resulting in more uniform heating of the food and ensuring improved taste and quality.

[0032] Specifically, the driving device 3 includes a motor 31 fixedly installed with the pot body 1. A drive gear 32 is fixedly installed at the output end of the motor 31. The drive gear 32 meshes with the driven gear 25 to rotate the steam inlet pipe 21.

[0033] Furthermore, a support roller 26 is installed at the end of the branch pipe 23, and the outer circumferential surface of the support roller 26 contacts the inner circumferential wall of the pot body 1. This is used to support the end of the branch pipe 23 and prevent the branch pipe 23 from bending at an angle due to the centrifugal force of rotation.

[0034] Specifically, a sleeve 221 is fixed to the left side of the turntable 22, and a connector 41 is fixed to the center of the right side of the material cylinder 4, connecting to the sleeve 221. Through holes 42 are evenly distributed around the circumference of the material cylinder 4, allowing the food inside to be more easily contacted by steam and also allowing water to flow out. The outer circumference of the support roller 26 contacts the outer circumference of the material cylinder 4. The support roller 26 provides support for the material cylinder 4 and, through contact with its outer surface, allows the material cylinder 4 to rotate around the center of the pot body 1, causing the food inside to rotate. Furthermore, the direction of rotation of the material cylinder 4 is opposite to the direction of rotation of the branch pipe 23, further increasing the uniformity of heating of the food.

[0035] Specifically, a material cylinder cover 51 is installed at the center of the inner side of the pot lid 5, which aligns with the left side of the material cylinder 4. This seals the left end of the material cylinder 4, preventing the food inside from slipping out during rotation.

[0036] The material cylinder 4 has ball bearings 43 distributed around its left circumference, and these ball bearings 43 contact the material cylinder cover 51. The contact between the left side of the material cylinder 4 and the material cylinder cover 51 through the ball bearings 43 reduces friction and prevents scratches from forming on the material cylinder 4 and the material cylinder cover 51.

[0037] Multiple spring posts 52 are installed between the material cylinder cover 51 and the pot lid 5. The spring posts 52 enable the material cylinder cover 51 to extend and retract, ensuring that the material cylinder cover 51 maintains a certain distance from the material cylinder 4 when closed, preventing the food from sliding out due to excessive distance or the pot lid 5 from not closing properly due to insufficient distance.

[0038] The bottom of the pot body 1 is fixed with a support base 13 for supporting the pot body 1 and keeping the pot body 1 at a certain height from the ground, so as to facilitate the collection space for the drain pipe 11 to discharge liquid.

[0039] The working principle of this utility model is as follows: The food to be sterilized is placed into the material cylinder 4, the pot lid 5 is closed, so that the material cylinder lid contacts the ball bearing 43 and the spring column 52 is compressed. Steam is introduced into the steam inlet pipe 21. The motor 31 is started to drive the active gear 32 and the driven gear 25 to rotate the steam inlet pipe 21. The turntable 22 and the branch pipe 23, which are fixedly connected to the steam inlet pipe 21, rotate synchronously. The fixed nozzle 243 sprays steam inward along the circumference of the pot body 1. While the rotating nozzle 245 rotates in the circumference, it slides along the wave groove 12 through the end of the guide roller 246 and rotates back and forth along the rotating pipe 244. By changing the spray angle, the area of ​​steam spray is increased. At the same time, the material cylinder 4 rotates in the opposite direction along the pot body 1 through the action of the support roller 26, so that the food inside rolls and the surface is heated evenly. The water flows out from the through hole 42 of the material cylinder 4 and flows out of the pot body 1 through the drain pipe 11 after the food is sterilized by high temperature steam.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
