The cooling process of poultry carcasses into cold water

摘要

The cooling process of poultry carcasses into cold water to this invention specifically addresses a new process for cooling in ice water birds whose main objective is to increase the striking manner the thermal exchange efficiency without using any type of heat exchanger of cal. Or health.Using the resources of this patent, it is possible to reduce the dependence of crushed ice in the process in 50% to 70% of investment in equipment for cooling and, in the same proportions, it is possible to reduce the energy costs of the central cooling.The basic principle is a better use of the potential of cold water contained in the renewal, whose rates are required by the federal sanitary legislation. By transferring the heat of the poultry carcasses in the water renewal makes that raises its temperature before being discarded in the sewer.In order to increase the thermal efficiency of the present invention proposes that the water renewal once chilled to a temperature of zero degrees Celsius to pass two or more tanks arranged in series in which the carcasses remain submerged in the water in each tank must be re The courses of circulating water in closed circuit and independent of other tanks using bombs hidru00e1uliCAS or agitators, equipped with propeller type naval. The calculations show that two or more tanks installed in series to increase significantly the thermal efficiency when compared with only one tank with single pass water.Once used a significant portion of the potential of cold water renewal, then calls in the last stage of cooling for the removal of the residual thermal load using this crushed ice. To facilitate and increase the thermal exchange between ice and water, it is preferable to interrupt wholly or partly the flow of water in the circulation, forcing it to cross a bank of crushed ice.The ice bank should preferably make water go down, and so the thrust that the ice sheet suffers when submerged in water prevents ice is not entrained in the water flow in circulation and to ensure that the water discharged in the sewer is free of particles of ice.
