摘要

Foodstuffs packaged in a microwave-transparent material are fed continuously ENVIRONMENT THROUGH A MAXIMUM PRESSING 2.5 bar, SO Prevent containers or wrappers bursting or are deformed; In four steps, the temperature rises rapidly to a value of PRESCRIBED TREATMENT WITH RADIATION A HIGH FREQUENCY MICROWAVE, STABILIZATION BY APPLICATION OF A COMBINATION OF MICROWAVE LOW TENSION AND HOT AIR PRESERVATION ASSURED WITH HOT ONLY AIR, AND QUICKLY DECREASE BY COOLING. IN AN OVEN CILINDRICO PARTY on two levels, the upper level consists of a clearing house pressure and temperature (4), a heat chamber at high speed (5) GENERATORS MICROWAVE WITH WALLS SEPARATE (24) arranged in rows LONGITUDINAL ALONG THE tops and sides, the waveguides (24 '', 25) which are directed to containers or wrappers (C) OF FOOD MATERIALS from above and below and are guided through special media (S ) and a settling chamber (5 '') IN WHICH THE MICROWAVE COMBINED WITH LOW TENSION FLOW THROUGH HEATER AIR (20) and circulated by a fan (21) located at the closed end of the furnace; The very air is used to heat a vertical chamber (6), through which DESCEND STANDS ON A LIFT (D) previously undergoing a cooling chamber (7) on the lower level and proceeding towards the final output THE clearinghouse (8). Once out of the oven, SUPPORTS (S) ARE RAISED BY A NEW LIFT (A) to the upper level for emptying and RECARGADO.FIG 1 and 3.
