In the field of food processing and preservation, retort sterilization occupy a key position. As a kind of modern fast-moving consumer food, canned bean products have won the favor of consumers for their convenience and taste diversity. Therefore, the safety of canned bean products has become the most concerned issue for enterprises. Sterilization of bean products has become particularly important. As a key sterilization equipment, how to give full play to the role of sterilization kettles in the entire canned bean production is the key factor to extend the shelf life of canned beans, confirm product safety, and improve product taste and texture. This article deeply explores the complexity of the sterilization process of canned beans, the processes involved, and the suitable types of sterilization kettles, etc., to help you better understand the importance of sterilization of canned beans.
1. What is a Retort Machine?
Retort is the cornerstone of modern food industry cooking and processing. It is a high-pressure and high-temperature sterilization equipment. Its function is to heat-treat packaged food at high temperature and high pressure, sterilize it at a certain temperature (usually around 121 degrees Celsius) and time, thereby eliminating microorganisms that may be harmful to the human body. Retorts come in a variety of different forms, including static, rotary and continuous, each of which is tailored to different product contents and product specifications.Inquiry now!
2. Why Canned Beans Need Retort Processing?
Canned beans are a ready-to-eat food that is loved all over the world. High-temperature sterilization of canned beans can effectively eliminate viruses and bacteria, extend the shelf life of the product, ensure product safety, maintain the nutritional content and quality of the product, etc. Canned beans that have been sterilized at high temperature do not need to be refrigerated and are convenient for storage and transportation. Retort machine has become a key equipment in the production and manufacturing of canned beans.
3. Sterilization Process of Canned Beans in a Retort Machine
The sterilization process for canned beans in a retort machine unfolds through meticulous steps:
•Preparation: Put the clean beans into cans, bottles or bags, seal them well and put them into the sterilization tray or basket. Make sure there is no foreign matter in the retort machine, push the product into the pot and prepare for sterilization;
• Heating stage: Steam is introduced for heating, and the temperature gradually increases until it reaches a predetermined level, usually between 115°C and 130°C, depending on the type of beans and the packaging material.
• Sterilization holding time: After reaching the optimal temperature, the beans are kept at this temperature for a period of time, which allows the heat to penetrate every part of the content, and the heat distribution is even, ensuring effective sterilization.
• Cooling and exhaust: After sterilization, the beans undergo a cooling cycle, in which cold water or air circulates to quickly reduce the temperature. Prevent over-sterilization and steaming, wait until the residual pressure in the pot is released, open the pot door, and take out the product.
• Inspection and labeling: After sterilization, the cans are inspected for deformation and damage, and the products are coded and labeled, etc., and finally packaged for distribution.Get Best Quote Now!
