Description

Technical Field

[0001] This utility model belongs to the field of shrimp shell production, and in particular relates to a vertical pressure steam sterilizer. Background Technology

[0002] The vertical pressure steam sterilizer used in shrimp shell production is a highly efficient sterilization device. Its core principle is to inactivate microorganisms by penetrating the material with high-temperature, high-pressure steam. The equipment mainly consists of a stainless steel inner tank, an electric heating system, an intelligent control panel, and multiple safety devices. The sterilization temperature is typically set above 121℃ and maintained for 15-20 minutes, effectively killing heat-resistant microorganisms such as spores. Compared to traditional boiling methods, the sterilization efficiency is increased by more than 50%, and the sealed design prevents the loss of nutrients from the shrimp shells.

[0003] Compared with Chinese Patent No. CN216853718U, a high-safety vertical pressure steam sterilizer for food is disclosed. It includes a sterilizer body, an inlet pipe fixedly connected to the right surface of the sterilizer body, an outlet pipe fixedly connected to the right surface of the sterilizer body, a motor fixedly connected to the top surface of the sterilizer body, and a sealing cover on the top surface of the sterilizer body. A movable storage device is provided inside the sterilizer body. This movable storage device allows the filter screen to be removed from the inside of the sterilizer body, reducing the risk of burns from the inner wall of the sterilizer body when handling food, thus improving the safety of the device. Liquids secreted by the food pass through the filter screen into the collection tank, thereby collecting the secreted liquids and reducing dripping onto the sterilizer body, ensuring the cleanliness of the inside of the sterilizer body.

[0004] However, the aforementioned patented food is kept stationary during sterilization, creating a completely static sterilization environment. This reduces the uniformity of contact between the pressurized steam and the material, slows down the sterilization process, and prolongs the sterilization time. Therefore, a new type of equipment needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a vertical pressure steam sterilizer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vertical pressure steam sterilizer includes an inner chamber for holding dried shrimp for pressure steam sterilization, and an outer chamber for introducing and discharging pressure steam for sterilization. The outer chamber has a lid for sealing and stirring, and the inner chamber is inserted inside it. The outer chamber includes a housing with several latches on its top and a drive assembly for providing rotational power at its bottom. An inlet / outlet assembly for introducing pressure steam and discharging wastewater is located on one side of the housing. The inner chamber includes a mesh cage assembly for passing pressure steam through for shrimp sterilization. Two lifting rings are symmetrically arranged on the top of the mesh cage assembly, and a limiting groove is provided on its bottom surface. The lid includes a sealing assembly with several locking hooks on its side and several stirring rods evenly distributed on its bottom surface.

[0008] Furthermore: the drive assembly includes a motor mounted at the center of the bottom of the chassis, and a rotating bracket is mounted on the output end of the motor; the inlet / outlet assembly includes an air inlet pipe disposed near the top of the chassis and a waste outlet pipe disposed near the bottom of the chassis, an air inlet valve is mounted on the air inlet pipe, and a waste outlet valve is mounted on the waste outlet pipe.

[0009] Furthermore, both the rotating bracket and the limiting groove are cross-shaped and are connected by plugging and unplugging.

[0010] Furthermore: the cage assembly includes a base plate, a fixed top frame is provided above the base plate, and a cage cylinder is installed between the base plate and the fixed top frame.

[0011] Furthermore: the base plate is circular, the fixed top frame is annular, and the mesh box cylinder is a cylindrical shape with a through-hole in the middle.

[0012] Furthermore: the sealing assembly includes a sealing cap, the top of which is provided with a handle and a pressure relief valve, and the bottom surface of which is attached with a sealing gasket.

[0013] Furthermore: the stirring rod is a cylindrical shape with a pointed bottom, divided into four groups of three, arranged in a cross shape.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. By driving the mesh box cylinder to rotate (rotary bracket transmission) with the electric motor and the relative movement with the fixed stirring rod, the shrimp shells are continuously turned over during the sterilization process, breaking the limitations of traditional static sterilization, significantly improving the uniformity of contact between steam and materials, and shortening the sterilization time;

[0016] 2. The four sets of stirring rods are arranged in a cross shape, which, together with the rotating mesh cylinder, creates a multi-dimensional mixing effect, solving the problem of incomplete sterilization in some areas caused by the clumping of shrimp shells; the through-cylindrical design of the mesh cylinder, combined with the downward flow of pressurized steam, ensures that the steam evenly covers all surfaces of the shrimp shells, avoiding sterilization dead spots;

[0017] 3. The inner box device (net box assembly) can be hoisted as a whole, and quick positioning and installation can be achieved through lifting rings and limiting grooves, simplifying the loading and unloading process; the outer box and the box cover are sealed and fixed by locks / hooks, which is labor-saving and reliable.

Connection; use the latch 108 on the top of the casing 101 to hook the locking hook 304 on the sealing cover 301 and pull it to fix it, so that the sealing cover 301 is pressed tightly against the casing 101 by the sealing gasket 305 to seal it. Then open the air inlet valve 105 to allow pressurized steam to enter the casing 101 through the air inlet pipe 104 and pass through the net cage cylinder 203 to sterilize the shrimp shells. At the same time, the motor 102 at the bottom of the casing 101 drives the rotating bracket 103 to drive the net cage cylinder 203 to rotate through the bottom plate 201, so that the shrimp shells in the net cage cylinder 203 move relative to the stirring rod 306 to form a stirring. After sterilization, first open the pressure relief valve 303 on the sealing cover 301 to release pressure, and then open the waste discharge valve 107 to discharge the condensed wastewater in the casing 101 from the waste discharge pipe 106.

[0028] In this embodiment: the inner box device includes a mesh box assembly for sterilizing shrimp shells by passing pressurized steam. Two lifting rings 204 are symmetrically arranged on the top of the mesh box assembly, and a limiting groove 205 is provided on the bottom surface of the mesh box assembly. The mesh box assembly includes a bottom plate 201, a fixed top frame 202 is provided above the bottom plate 201, and a mesh box cylinder 203 is installed between the bottom plate 201 and the fixed top frame 202. The bottom plate 201 is circular, the fixed top frame 202 is annular, and the mesh box cylinder 203 is a cylindrical shape with a through center.

Then, the locking hook 108 on the top of the machine housing 101 is hooked onto the locking hook 304 on the sealing cover 301 and pulled to fix it, so that the sealing cover 301 is pressed tightly against the machine housing 101 by the sealing gasket 305 to seal it. Then, the air inlet valve 1 is opened. 05. Pressurized steam is introduced into the machine housing 101 through the air inlet pipe 104 and passes through the mesh cage cylinder 203 to sterilize the shrimp shells. At the same time, the motor 102 at the bottom of the machine housing 101 drives the rotating bracket 103 to rotate the mesh cage cylinder 203 through the bottom plate 201, so that the shrimp shells in the mesh cage cylinder 203 move relative to the stirring rod 306 to form a stirring, which improves the uniformity of pressurized steam sterilization and speeds up the pressurized steam sterilization.
