within the mixing chamber and then compressed to obtain condensation of steam within the product application_number US 55560100 A description the main distinctive feature of the method of the invention is the increase in speed of product fed to the mixing chamber namely the product is accelerated at entry to a maximum permissible speed matching processing operating conditions while not exceeding the speed at which the static pressure of the flow matches the saturation pressure at an input temperature of the product the maximum speed according to the liquid flow speed curve in the injector channel before steam feeding being observed at the output cross sectional area of the product nozzle these features separately and in the aggregate provide for new good properties listed below firstly a new injector has been created based on a new conception which includes methods of operation of two prior art injectors steam liquid injector which uses steam as a process medium and liquid as injected medium see 9 pp steam liquid injector which uses liquid as a process medium and steam as injected medium see 9 pp the new method of injector operation combines advantages of steam liquid injectors good operating characteristic especially of those with supersonic steam flow and two phase steam liquid mixtures and liquid steam injectors easy to handle reliable start stable performance in addition the new injector based on the new method is free.
