A method of heat treatment of products advanced through a chamber by circulation through the chamber of hot, humid air that is evacuated, is supplied with humidity and heat and then blown back to the chamber, includes the step of supplying heat and humidity to the air by atomization into the circulating air of excess water of a temperature higher than that intended in the chamber. An apparatus for carrying out the method includes a chamber comprising one or more subunits, through which subunit(s) the products to be thermally treated are passed, a fan which on its draught side is connected with the subunit for exhaustion of the humid air and on its delivery side with a flow passage for blowback of the humid air to the subunit, and a water atomizer for water of a higher temperature than that desired in the scalding chamber. The method provides for obtaining a stable heat treatment at varying load and actions of heat and cold.
A method of scalding of carcasses advanced through a chamber comprising circulating hot humid air through the chamber by the continuously repeated steps of:
An apparatus for scalding of carcasses advanced through a chamber comprising one or more subunits through which the carcasses to be scalded are passed, each subunit comprising a fan which on its draught side is connected with the subunit for exhaustion of the humid air from the subunit, and on its delivery side with a flow passage for blowback of the humid air to the subunit and each further comprising a water atomizer for water of a higher temperature than that desired in the subunit and a heat source for heating the water to be supplied to the water atomizer.
An apparatus for scalding of carcasses advanced through a chamber, comprising one or more subunits through which subunit(s) the carcasses to be scalded are passed, each subunit comprising a fan which on its draught side is connected with the chamber for exhaustion of the humid air from the chamber, and on its delivery side with a flow passage for blowback of the humid air to the subunit, and each further comprising a water atomizer discharging into the duct for water of a higher temperature than that desired in the chamber, a basin communicating through a pump with said water atomizer being located under the water atomizer in the flow passage, and a heat exchanger located in or in connection with said basin for heating water recirculated from said basin by means of a pump through said heat exchanger to said water atomizer, the supply of heating liquid to the heat exchanger being controlled by the air temperature in the subunit by means of a regulator.
