Sterilization retorts (autoclave) are pressure vessels. It is composed of tank body, head, pipe fittings, flange, saddle, sight glass, reinforced rib plate, welding seam, plate, safety interlocking device, etc.
Main application areas of retort machines
Retort machines are mainly used in various fields such as the food and beverage industry, medicine (health products), etc.
Retort machine is mainly suitable for packaging
Tetra Pak, retort bags, vacuum bags, aluminum foil bags (vacuumed or filled with nitrogen), glass containers, stand-up bags, plastic containers (PP, PE bottles, cup porridge), boxes, casings, metal containers (three pieces cans, two-piece cans, tinplate, aluminum cans), small gold bowls and other packaging.


The main types of our sterilization retorts
Water spray sterilization retorts
Water immersion sterilization retorts
Steam-air sterilization retorts
Laboratory pilot retorts
Rotating sterilizing retorts



Other devices
Electric trolley (controls and transports baskets at both ends to realize automatic entry and exit of material baskets into the sterilization retort)
Automatic/semi-automatic cage loading and unloading system (automatically places product codes in cages to achieve automatic/semi-automatic cage loading and unloading).



Taking the application of sterilizing retorts in the production of cup porridge products as an example, what is the working principle of sterilizing retorts?

Nowadays, instant breakfast porridge on the market has become a daily ubiquitous product, and the packaging is also diverse, such as: tin cans, bags, bowls and cups, etc.

The extended shelf life of instant porridge products is due to the improvement of the sterilization process. After the raw material is filled once, the aging and sterilization process is completed at high temperature in a sterilization retort machine.

Compared with other models, the rotary high-temperature sterilization retort machine is more suitable for sterilizing highly viscous materials such as eight-treasure porridge, breakfast porridge, bird's nest, meat sauce and mushroom sauce. The food rotates continuously and slowly in the device, making it transfer more quickly and evenly, preventing rice accumulation and sedimentation leading to incomplete sterilization, greatly shortening the time of the entire sterilization process, and achieving high-temperature short-term sterilization. At the same time, overheating around the food can be avoided.

SUMPOT's fully automatic rotary high-temperature sterilization retort adopts Siemens PLC controller. The temperature control system can flexibly control automatically according to the characteristics of different packaging materials. The pressure control system automatically adjusts the pressure in accordance with the standard mode and performs back-pressure correction according to different situations. , which is very beneficial to prevent the deformation and damage of the container and improve the yield.



Some features of our sterilization retort machines
1. The temperature control system can choose linear or step heating modes according to different products and processes. The temperature can be accurately controlled at ±0.05Bar, with uniform heat distribution, large processing capacity, and uniform sterilization effect;
2. The liquid flow switching device disperses the water flow to the center of the product tray to achieve a uniform sterilization effect;
3. The steam heats up directly, without the need to heat other media, and the temperature rises very quickly;
4. It can have steam, spray, water bath and rotation functions at the same time;
5. Develop sterilization formulas for new products, simulate actual sterilization environments, reduce R&D losses and improve the yield of mass production;
6. Spray type, water immersion type, and steam type sterilizing pots can all add rotation options, which are suitable for sterilization of various packaging forms;

Sterilization retort operation safety procedures
The following checks should be carried out before the equipment is started.
The condition of the equipment should be checked for abnormalities and obvious defects;
Safety devices, pressure gauges, thermometers and other accessories must be kept complete, sensitive and reliable;
Pipe joints and valves have no leakage;
Check the operating parameter requirements, operating process indicators and regulations on maximum working pressure, maximum or minimum working temperature;
There are no foreign objects (such as tools, rags, etc.) on the corresponding production lines and equipment;
Make sure there are no people inside or near the machine;
