The sterilizing retort in the food industry is a key equipment, it is used for high-temperature and high-pressure treatment of meat products, protein drinks, tea drinks, coffee drinks, etc. to kill bacteria and extend the shelf life.
The working principle of the sterilization retort mainly covers key links such as heat treatment, temperature control, and the use of steam or hot water as the heat transfer medium. During the operation, effective sterilization of food or other materials is achieved through a series of processes such as heating, sterilizing and cooling. This process ensures the stability of the sterilization effect and product quality.
There are various types of sterilizing retorts, mainly divided into two categories: static type and rotary type. Among static sterilizers, common types include steam sterilizers, water immersion sterilizers, water spray sterilizers, and steam air sterilizers. The rotary sterilizing retort is more suitable for products with higher viscosity, such as porridge, condensed milk, evaporated milk, etc. During the sterilization process, this equipment can make the sterilized products rotate 360 degrees in all directions within the cage. This not only helps to improve the heat transfer efficiency, but also effectively shortens the sterilization time, while ensuring the taste of the food and the integrity of the packaging, thereby improving the overall product quality.
When selecting a suitable retort, it is necessary to comprehensively consider many factors such as temperature control accuracy, heat distribution uniformity, product packaging form and product characteristics. For air-containing packaging, glass bottles or products with high appearance requirements, you should tend to choose sterilization retorts with more flexible temperature control and air pressure functions, such as spray sterilization equipment. This type of equipment can effectively prevent product deformation and ensure product quality through linear temperature and pressure control technology. For products packaged in tinplate, due to its strong rigidity, steam can be directly used for heating without the need for indirect heating through other media. This move not only significantly improves the heating speed and sterilization efficiency, but also helps reduce production costs and optimize economic benefits.
In addition, during the purchase process, you must choose a manufacturer with a formal pressure vessel manufacturing license to ensure the quality and safety of the product because the retort is a pressure vessel. At the same time, the appropriate model and operation method should be carefully selected based on the daily output and automated production needs of the factory, so as to ensure that the retort can fully meet the actual production needs of the factory.
