Description

This invention relates to the processing of trolleys, and more particularly to a system for processing products loaded on trolleys by methods such as sterilization, and to packing included therein. Retort foods refer to foods that are formed by applying high heat to sealed food and beverage products for sterilization, followed by rapid cooling. A retort sterilizer is a device used in the manufacturing process of such retort foods to apply high heat to sealed products. Various methods have been applied to uniformly and thoroughly sterilize products, process large quantities of products in a short time, and increase product production efficiency. A batch method can be used, where products are loaded onto a trolley and entered into the sterilizer, carrying out all processing steps, including sterilization, simultaneously. However, this method suffers from low thermal efficiency, requiring additional heat treatment time, resulting in uneven heat distribution and inconsistent heating. A continuous system can be used, where products are transported continuously, with each product processed in its own separate space. However, this system presents problems such as excessively long overall equipment length, difficult access for workers due to its complex structure, and challenging maintenance. Furthermore, while systems have emerged to compensate for the disadvantages of continuous and batch systems, for safety reasons, the entire sterilization system must be designed to conform to the standards of a pressure vessel. In particular, in some countries, the entire sterilization system is treated similarly to a pressure vessel, and distribution is permitted only when it meets the design requirements of a pressure vessel. Therefore, even when compensating for the disadvantages of continuous and batch systems, there remains the problem that system deformation must occur within a structure that ensures sufficient airtightness between each component to meet the design requirements of a pressure vessel.
