Upgrading Air Distribution System in the Thermal Units for Fish and Meat Products Aiming at Improving Efficiency of Heat-exchange Processes

The issue of the equivalence physical parameters working medium in heat-treatment zone fish and meat products is solved by organizing uniform high-speed fields area, which ensured corresponding design. aerodynamic characteristics a double-sided centrifugal blower fan with vertical arrangement drive shaft spiral scroll two outlet openings, outlines were carried out according to design square rule, provided that opening width each was equal half-opening half-width case industrial prototype, investigated. When testing blower, identities full dynamic air pressure developed at all points measured cross-section oppositely directed pipes are established be identical, indicates equalization flows. In this case, dimensionless ratio cross-sectional areas equistatic duct initial 0.20, area for passage heat exchanger, conditionally being perforated base duct, 0.0978 m2 . test results confirmed reliability analytical calculations feasibility using these fans, reduces energy consumption, specific quantity metal, cost equipment general.
