Modernization of the apparatus for heat treatment of canned food

At modern processing plants, a vertical autoclave of the two-wire type B6-KAV-2 is used. The autoclave is used for heat treatment of products placed in baskets. The autoclave consists of the following elements: a housing sealed with a lid, a lower device for supplying the working medium made in the form of a perforated annular tube. The disadvantage of the autoclave lies in the significant unevenness of the temperature field inside it, since the local nature of the supply of the working medium through the annular pipe located close to the bottom of the lower basket, as well as the lack of intensive circulation and mixing of the working medium in the autoclave will in any case lead to the formation of a significant difference in thermal potentials in the area of supply of the working medium, as well as in areas that are remote from the place of supply of the working medium. This leads to an increase in canned food sterilization time, which contributes to a decrease in the productivity of the canned food production plant. In order to improve the quality of heat treatment of products by improving circulation and mixing of working media, as well as to create a uniform temperature field, an improved apparatus B6-KAV-2 for heat treatment of canned food should be used in the autoclave. In the improved autoclave, it is necessary to replace the lower stationary device for supplying the working medium, made in the form of a perforated annular tube, with movable devices for distributing working mediums. These devices are installed at the bottom and top of the chassis. Each device for supplying working media is made in the form of a vertical hollow shaft with hollow blades fixed to it at an angle and equipped with horizontal nozzles.
