Equipment design standards and regulations:

(1) Plastic containers: PP bottles, HDPE bottles;

(2) Soft bag packaging: aluminum foil bag, high temperature transparent bag, high temperature vacuum bag, etc.;

(3) Suitable for all kinds of high temperature resistant packaging materials;

Safety of equipment use:

•1. One-button start, fool-like operation; all control and display devices are concentrated on the touch screen, which does not require personnel to operate at close range, ensuring personnel safety;

•2. The sterilization part of the equipment is a pressure vessel. The conventional pressure resistance is 0.3Mpa. The customer's operating pressure is generally 0.2Mpa. In order to ensure 100% safety in use, the design of the pot body fully takes into account all possible risk factors. From the design to the selection of accessories, everything is very strict. All materials, labor, accessories, production processes, etc. are all recorded. Any problems can be traced to the source; and the National Special Equipment Inspection Agency serves as a third party to supervise and inspect the whole process, signing Confirmation; In order to ensure absolute completeness, the equipment is equipped with a pneumatic pressure relief valve and a double mechanical safety valve to ensure that under any circumstances, the equipment will not have product pressure overload problems;

•3. The equipment is designed and equipped in strict accordance with the principle of humanization. When the equipment is sterilizing, no matter how workers misoperate, the pot door will not be opened to cause harm.

 4. Safety pot door----simple operation and high safety performance. The structural design is simple and easy to operate and maintain. The quick-opening pot door structure realizes three interlocks (mechanical interlock, safety pneumatic interlock, and electronic induction interlock). The three interlocks work together to ensure safe and reliable operation.
·Proximity switch, safety cylinder and mechanical interlocking device are triple interlocked, safe and reliable.
· The self-sealing function is added to the pot, the compressed air source pressure is insufficient, the pot door sealing ring seals normally, and the equipment operates normally.
· Electronic safety protection, it cannot operate if the door is not closed in place.
· Mechanical safety protection, if the safety chain lock device is not closed in place, the pressure in the pot will be discharged to the outside of the pot, and no pressure will be generated in the pot.
·Check the pressure of the pot door sealing ring. If the pressure is too low, it will cause leakage and the program will control the equipment to be unable to operate. You need to check whether the air compressor is operating normally.
·The air introduction valve is used to maintain smooth communication with the outside world at the end of the program and create a pressureless state in the pot.
 

5. Safety valve
Safety valve is an overpressure protection device on pressure equipment (such as containers, pipelines). When the equipment pressure rises to a predetermined value, the safety valve automatically opens to relieve pressure to prevent the equipment pressure from continuing to rise. When the pressure drops to the specified value, the safety valve automatically closes in time to prevent a large amount of medium loss in the equipment. The opening and closing parts of the safety valve are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, the medium pressure in the pipeline or equipment is prevented from exceeding the specified value by discharging the medium outside the system. Safety valves are automatic valves that are mainly used in boilers, pressure vessels and pipelines to control pressure not to exceed specified values and play an important role in protecting personal safety and equipment operation.
6. The rotating part of the arm device adopts a self-made copper sleeve, which reduces the wear between the main shaft and the sleeve.
The service life of the spindle is increased and the door opening position is accurate without deviation.

The heat distribution in the sterilizing pot is easy to achieve uniformity;

1. The water spray type uses a large-flow water pump to pour sterilizing water down from the top packaging. The water passes through the packaging from top to bottom, and the heat is also transferred to the food in the form of a water film on the packaging. . Sterilizing water is also heated and cooled through a heat exchanger. The water flowing down gradually releases heat from top to bottom as it heats up, and the temperature also decreases in turn. However, after reaching the target temperature, the upper and lower temperature differences will become consistent. Heat is also forced to the packaging by the water flow, and the transfer will not be interfered by the presence of cold air in the pot. The upper and lower temperature differences formed during the heating stage will tend to be consistent during heat preservation, and will not cause heating cold spots in local spaces. Although the food in the upper part takes longer to heat than the food in the lower part, when it cools down, the food in the upper part will also cool down earlier than the food in the lower part, and the overall temperature will be the same on average. Sterilizing water source with consistent temperature and layered and independently placed packaging are the keys to uniform heat distribution in the pot.

2. The top shower partitions of Qingshi Company are segmented. A top shower partition is evenly distributed on the top of each basket to ensure uniform heat distribution of the sterilization materials in each basket. There are reinforcing ribs in the middle of each partition to prevent the middle part from natural Sagging causes uneven top pouring, and the partitions are like drawers, making them easy to disassemble and clean.

3. The spray device of the sterilization kettle is welded with stainless steel round pipes. By optimizing the internal spray structure (one-to-two, two-to-four mode), the water pump flow rate is accurately calculated and strictly controlled. The small hole cross-sectional area and spray partition of the spray branch pipe are The cross-sectional area of the water holes in the plate keeps 3cm-4cm of water in the upper space of the spray partition, which increases the turbulent effect of circulating water in the pot (the straight spray pipe is connected with a union and can be removed and cleaned).

▶ An automatic condensate drain valve (automatically controls the opening of the trap)
▶ A water trap (automatically removes condensed water in the heat exchanger, blocks steam and drains water)
▶ A hydrophobic filter (automatically protects the trap and prevents it from clogging)
4. The centrifugal pump used for cyclic sterilization has a model and size that ensures that the process water in the pot can circulate 3 to 4 times a minute. All pipeline connections between containers and pump connections are made of stainless steel.
High degree of automation:
The control of the entire sterilization process can be completed on the touch screen. The sterilization process requirements such as temperature, time, sterilization pressure, cooling pressure, cooling temperature and other functions can be customized according to different models. The temperature control accuracy can reach ±0.2℃, and the pressure control accuracy can reach ±0.01Mpa. Hundreds of sterilization process procedures can be stored, which greatly reduces the labor intensity of operations and improves production efficiency.

Stable control system:
1. The liquid level gauge adopts a magnetic float level gauge with automatic liquid level remote transmission and liquid level display functions, which makes the liquid level control more accurate and effectively solves the problem of inaccurate signal transmission of the photoelectric liquid level gauge. The liquid level gauge pipe is equipped with a reinforced fixing device to prevent cracks or breaks in the liquid level gauge pipe due to vibration during the sterilization process.
2. Computer fully automatic PLC program automatic control, touch screen command input. Adopting a world-renowned brand (Siemens), it has stable operation, accurate temperature and pressure control, and low failure rate. With the automatic storage function of the sterilization process, each product/container can be equipped with a different formula because the number of programs is not limited. Consistently high product quality is guaranteed through extremely precise preset temperature and pressure distribution. Touch screen operation interface, dynamic picture display, parameter values can be set arbitrarily according to product requirements.
 
3.Equipment production details:

1. The highest quality flanges, heads and other parts in China are used. The heads are formed by one-time cold pressing and undergo aging vibration, so there will be no stress deformation during use.
2. The advanced and stable Siemens SIEMENS control system ensures that customers can find supply chains in a timely manner around the world and reduce downtime.
3. Rare high-end equipment and strict production process control management in the industry ensure the first-class quality of the complete machine.
