Description

Technical Field

[0001] The utility model relates to the technical field of sterilization of prefabricated dishes, and particularly relates to a sterilization device for prefabricated dish production. Background Technique

[0002] Prefabricated dishes are also called prefabricated and conditioned foods. Generally, they refer to the use of modern standardized assembly line operations to pre-process food materials. After the prefabricated dishes are produced and packaged, the bagged prefabricated dishes usually need to be sent to the conveyor belt of a microwave heating sterilizer. After the bagged prefabricated dishes pass through the chassis of the microwave heating sterilizer through the conveyor belt, the microwave heating sterilizer allows microwave electromagnetic waves to pass through the medium by microwave heating. At this time, polar molecules (such as water molecules) generate violent movements with the high-frequency alternating electric field of the microwave, forming a thermal effect to coagulate and denature the microbial protein, thereby destroying the cell structure and function of bacteria and achieving the sterilization effect of prefabricated dishes.

[0003] When the existing microwave heating sterilizer sterilizes prefabricated dishes, a fan is usually used at the top air outlet of the microwave heating sterilizer to perform heat dissipation, temperature control and auxiliary uniform heating functions. However, there is usually only one fan at the single air outlet of the microwave heating sterilizer. When the fan at a high position fails, it is often difficult for technicians to detect, which affects the sterilization effect of the microwave heating sterilizer. For this reason, we propose a sterilization device for prefabricated dish production. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a sterilization device for prefabricated dish production. By configuring a double-row mechanism at the exhaust heat pipe of the microwave sterilizer body, the main fan and the auxiliary fan of the double-row mechanism can form an exhaust heat structure for alternating use at the exhaust heat pipe. Under normal conditions, the main fan operates independently to exhaust heat. When the pipeline wind speed sensor probe detects abnormal wind force in the pipeline where the main fan is located, it can be manually switched to the auxiliary fan to continue working through the controller, avoiding the risk of temperature out-of-control inside the microwave sterilizer body due to a single fan failure and affecting the sterilization effect of prefabricated dishes. This double-fan backup mechanism can effectively reduce the shutdown risk of the microwave sterilizer body caused by fan failures, ensure the continuity of the prefabricated dish sterilization process, and pipeline wind speed sensor probes are installed at the flange joints where the main fan and the auxiliary fan are located. The real-time monitored wind force data can be provided to the controller for linkage alarm according to control requirements, which is convenient for discovering the failures of the main fan and the auxiliary fan for maintenance. It can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A pre-prepared food production sterilization equipment includes a microwave sterilizer body and a heat exhaust pipe. The top of the microwave sterilizer body is welded with heat exhaust pipes. It also includes a double-row mechanism, which comprises a central connecting pipe, a U-shaped bend branch pipe, a flange connecting pipe, a main fan, a secondary fan, a U-shaped bend manifold, a flange connecting pipe, a pipeline anemometer probe, and a top row of pipes. The top flange of the heat exhaust pipe is connected to the central connecting pipe, and the upper opening of the central connecting pipe is welded with a U-shaped bend branch pipe. The tops of the two vertical sections of the U-shaped bend branch pipe are symmetrically welded with flange connecting pipes. The top flanges of the two sets of vertical sections of the flange connecting pipe are connected to the main fan and the secondary fan. The upper shells of the main fan and the secondary fan, away from the flange connecting pipes, are connected with flange connecting pipes, and the flange connecting pipes are symmetrically welded to the vertical sections of the U-shaped bend manifold. The top of the central section of the U-shaped bend manifold is welded with a top row of pipes. The probe head of the pipeline anemometer probe is inserted into the vertical section of the flange connecting pipe.

[0007] Furthermore, a surface hole ring is welded to the outer side of the bottom tube of the intermediate pipe, and the surface hole ring of the intermediate pipe and the surface hole ring of the heat dissipation pipe are locked together by bolts.

[0008] By adopting the above technical solution, the surface hole ring of the central pipe and the surface hole ring of the heat dissipation pipe can be screwed in with bolts for locking.

[0009] Furthermore, a surface ring is fixed to the outside of the flange connecting pipe, and an installation hole for vertical screw bolts is opened between the surface ring of the flange connecting pipe and the shell rings of the main fan and the auxiliary fan.

[0010] By adopting the above technical solution, the flange connecting pipe has a face hole ring plate that matches the bolts, which can be locked to the shell rings of the main fan and the auxiliary fan for installation.

[0011] Furthermore, a surface-hole ring is welded to the outside of the flange pipe body, and mounting holes for vertical screw bolts are opened between the surface-hole ring and the shell rings of the main fan and the auxiliary fan.

[0012] By adopting the above technical solution, the flange ring can be installed by bolting it to the other end of the shell ring of the main fan and the auxiliary fan.

[0013] Furthermore, the flange connector has a side opening on the outside of the vertical pipe body for mounting and bonding a rubber frame seat, and a central hole rubber block is inserted and bonded inside the rubber frame seat, and a pipe anemometer probe is inserted into the flange connector inside the central hole rubber block.

[0014] By adopting the above technical solution, after the rubber frame seat is installed and bonded at the flange connection, the probe head of the pipeline anemometer can extend into the flange connection from the rubber frame seat to detect wind force.

[0015] Furthermore, the U-shaped bend branch pipe has symmetrically welded feet below the pipe body away from the central pipe, and the T-shaped foot plate of the foot is provided with mounting holes for screw bolts between the foot plate and the shell of the microwave sterilizer body.

[0016] By adopting the above technical solution, the U-shaped bend branch pipe has a support foot below it, which can be installed on the top of the shell of the microwave sterilizer body by means of bolts.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention features a dual-row mechanism at the heat exhaust pipe of the microwave sterilizer body. The main fan and auxiliary fan of the dual-row mechanism can form an alternating heat exhaust structure at the heat exhaust pipe. Under normal conditions, the main fan operates independently to extract and exhaust heat. When the pipe anemometer probe detects abnormal airflow in the pipe where the main fan is located, the auxiliary fan can be manually switched to continue working via the controller. This avoids the impact of a single fan failure on the sterilization effect of the prepared food due to uncontrolled internal temperature of the microwave sterilizer body. This dual-fan backup mechanism can effectively reduce the risk of downtime of the microwave sterilizer body due to fan failure and ensure the continuity of the sterilization process of prepared food.

[0019] Furthermore, duct anemometer probes are installed at the flange connections of both the main and auxiliary fans to monitor wind speed data in real time. This data can be provided to the controller for linkage alarms as needed, facilitating the detection and repair of faults in the main and auxiliary fans. Attached Figure Description

[0031] By adopting the above technical solution, the flange connecting pipe 10 can be installed by bolting it to the other end of the shell ring of the main fan 7 and the auxiliary fan 8.

[0032] The flange connector 10 has a side opening on the outside of the vertical pipe body for mounting and bonding a rubber frame seat 11, and a central hole rubber block is inserted and bonded inside the rubber frame seat 11, and a pipe anemometer probe 12 is inserted into the flange connector 10 inside the central hole rubber block.
