Types of Steam Retort Machine
The steam retort machines produced by our company mainly include the following types

Milk Steam Sterilizer
The use of sterilization retorts for milk products varies depending on the packaging form. Canned milk can be sterilized using steam sterilizer, glass bottle milk can be sterilized using spray sterilizer, and bagged milk can be sterilized using water bath/water immersion sterilizer.

Static Steam Sterilizer
Static steam sterilizer, bases its operation on the transmission of hot and cold water through re-movement through exchanging heat plates either in spray or cascade or steam.

Automatic Steam Retort
Steam retort directly heats food with steam entering the kettle, without any other heating medium , the steam is uniform. Throughout the entire process, the pressure inside the sterilization kettle is controlled by the program through high-precision steam film valves to send or discharge compressed air into the sterilization kettle.
Advantages of Steam Retort Machines
The heating and cooling speed is fast, and it can reach very high temperatures and pressures quickly, greatly shortening the sterilization time
The maximum temperature is 135°C, and the sterilization effect is good. Under high temperature and high pressure, almost all germs can be killed
Strong penetrating power, steam can penetrate thick breathable objects and kill spores
Easy to operate, large-inch color touch screen, multi-language switchable, easy to operate after simple training
Save time, and use time more effectively through functions such as scheduled start and preheating functions
Various programs. In addition to setting each sterilization program, you can also set any project for repeated operations
Shorten the take-out time, and the cooling fan is equipped as standard. After the sterilization is completed, the cooling fan will operate to quickly cool down to a safe temperature
High safety, with safety lock settings, over-temperature and over-pressure protection devices, and water and power outage protection functions
Computer control, no need for human supervision, saving human resources and other advantages.
Applications of Steam Retort Machine
Sterilization of canned food
Steam retort machine plays a key role in canned food production. It can kill bacteria, fungi and other microorganisms inside cans, ensuring the safety and shelf life of food. By precisely controlling the temperature and pressure of the steam, as well as the sterilization time, the steam retort machine can provide personalized sterilization treatment for different types of canned foods.
Sterilization of beverage bottles
The beverage industry also widely uses steam retort machines to sterilize beverage bottles. Steam sterilization of beverage bottles before filling can effectively remove microorganisms inside the bottles and prevent contamination during storage and sales. The steam retort machine can quickly heat up and maintain a stable temperature, ensuring that each beverage bottle can receive sufficient sterilization treatment, improving product quality and safety.
Sterilization of medical devices
In the medical field, steam retort machine is one of the important equipment for sterilizing medical devices. Surgical instruments, syringes, infusion sets and other medical devices must undergo strict sterilization treatment before use to prevent cross infection. The steam retort machine can thoroughly kill various bacteria, viruses, and spores on medical devices under high temperature and pressure, ensuring the safety of medical operations.
Sterilization of laboratory supplies
The culture dishes, test tubes, pipettes and other supplies in the laboratory also need to be sterilized regularly. Steam retort machine can provide a reliable sterilization solution for laboratories, ensuring the accuracy and reliability of experimental results. At the same time, the precise control function of the steam retort can meet the sterilization requirements of different laboratory supplies and improve the work efficiency of the laboratory.
Precautions for Using Steam Retort Machine
The sterilization temperature and time must be accurately controlled. Steam retort canned products with high-temperature steam. Therefore, the temperature and time of steam must be strictly controlled to ensure that each part of the product can achieve the required sterilization effect. At the same time, avoid over-sterilization to avoid adverse effects on the taste and color of the product.
Pay attention to pressure control during sterilization. Steam retort machines need to maintain a certain pressure range during sterilization to improve the sterilization effect. However, excessive pressure May cause the product packaging to rupture or deform. Therefore, the pressure must be adjusted reasonably according to the actual situation.
Before sterilization, the product should be pre-treated. Including cleaning, packaging, etc., to ensure that there are no impurities on the surface of the product and the packaging is well sealed. This can not only improve the sterilization effect, but also prevent the product from being contaminated during the sterilization process.
The operators of steam retort machines must receive professional training and be familiar with the operating procedures and safety precautions of the equipment. During use, pay close attention to the operating status of the equipment and promptly discover and deal with abnormal situations. At the same time, regularly maintain and service the equipment to ensure its normal operation and extend its service life.
