Abstract

The article grounds economic expediency of using jacket thermal exchangers of the sheet-canal type. As a rule steam jackets of technological devices in food industry and catering enterprises have a form of an open slit space and for work under pressure they are made of walls of big thickness, which envisages their high metalconsumption. In contrast to standard slit jackets, sheet-canal panels are a structure made of two thick metal sheets welded by contact electric welding. Heating steam canals are formed between the sheets. Such structure allows us to decrease the wall thickness and therefore to cut metal-consumption and, consequently power-consumption of technological equipment. The article describes the method which could optimize sizes of inter-canal zones of sheetcanal panels used as jackets in devices of thermal treatment of food. In order to cut wall thickness of panels it is proposed to increase the square of inter-canal zones without declining the total thermal flow, which is passed by the panel to the agent being heated. This problem was resolved by the calculation method based on the use of thermal rib efficiency coefficient. The authors made calculations and provided optimal sizes of inter-canal zones in case of altering the wall thickness of jacket thermal exchanger made of chrome-nickel stainless steel of the brand 12X18H9T.
