Food safety is no small matter. Upgrading the disinfection and sterilization technology of food production enterprises to high-end is an inevitable trend of the development of the times. Only by ensuring the safety and hygiene of the food produced can enterprises flex their muscles in occupying the market. However, due to the requirements of food packaging formats, some food companies, especially glass bottles and gas-packed products, are sensitive to cold and heat, and are prone to bottle explosion problems during the sterilization process, which has always been a problem for food production companies.
Jinding Food Machinery Co., Ltd. has developed a new spray-type sterilizing retort based on the traditional sterilizing retort through the joint efforts of all employees, so that the products in the retort chamber can be completely evenly pressured and heated, and the products can break the bottles in the actual application of customers. The rate is almost zero, effectively solving this sterilization problem. The spray method has played an absolute role in promoting the development of flexible packaging. Spray-type sterilization method are divided into: top-spraying sterilizing retort, side-spraying sterilizing retort, and full spraying sterilizing retorts. Water spray retort is made of stainless steel and has the characteristics of beautiful appearance, hygienic safety and durability. In addition, the chamber lid is sealed with an inflatable silicone rubber temperature-resistant sealing ring, which has reliable sealing and long service life. The bottled beverage sterilizing retort has the advantages of large heating area, high thermal efficiency, uniform heating, short boiling time of the liquid in the spray sterilizing retort, and easy control of the heating temperature.
Principle of water spray retorts
water spray retort machine injects a small amount of process water to a predetermined position (the product cannot be soaked). The water is injected into the spray pipe through a high-efficiency circulation pump-filter-high-efficiency heat exchanger, and then the hot water is sprayed out through the spray nozzle to atomize it. shape to the surface of the food, the heat is evenly distributed in the pot, and there are no sterilization dead corners. The water is indirectly heated and cooled through the heat exchanger. The heating and cooling speeds are rapid, and the product can be sterilized efficiently, comprehensively and stably.
Features of water spray retorts
1. Indirect heating and indirect cooling, the cooling water does not come into contact with the process water, which avoids secondary pollution of food and does not require water treatment chemicals. High temperature and short time sterilization.
2. Reduce steam consumption. The sterilized water after steam atomization is mixed directly in the sterilization kettle to increase the speed of heating and cooling.
3. Low noise, creating a quiet and comfortable working environment.
4. Water is sprayed from different angles, and steam, air and water mix and convection to form a perfect temperature distribution.
5. A small amount of process water is quickly circulated to quickly reach the predetermined sterilization temperature.
6. The kettle can be equipped with four movable temperature sensing probes, which can monitor the heat distribution in the kettle at the F value of the food center at any time and understand the heat penetration (the time it takes for the temperature to reach the geometric center of the food from the surface of the food) at any time. 7. Perfect pressure control, the pressure in the entire production process is constantly adjusted to adapt to changes in the pressure inside the product packaging, so that the deformation of the product packaging is minimized, especially suitable for products containing gas packaging. 68. The process water preheating system can ensure that the thermal insulation and hot-filled products receive a continuous heating process. 9. Use softened water for sterilization water to avoid water quality problems of process water and cause no dirt on the outer packaging points.
10. Steam sterilization function
11. Save installation space, facilitate operation, and save manpower (only need to use the control cabinet for direct operation).
12. Suitable for beverage and other food industries, automatic loading and unloading of materials during large-scale production. More convenient for automatic configuration of equipment in unmanned workshops in the future industry
Scope of application of water spray retorts
water spray retort machine is suitable for all types of high temperature resistant packaging materials
1. Plastic containers: PP bottles, HDPE bottles.
2. Soft bag packaging: aluminum foil bags, transparent bags, vacuum bags, high temperature cooking bags, etc.
3. Tinplate cans, aluminum cans and glass bottle products
