ABSTRACT:
A rotary blancher that is sealed such that it can be positively pressurized during operation to a pressure greater than the ambient pressure outside the blancher to increase food product heating speed and efficiency. The blancher has a sealed housing, a sealed food product inlet, and a sealed food product outlet all for enabling an atmosphere inside the blancher to be positively pressurized. A heat transfer medium, such as a heated gas, a heated vapor, a heated liquid, or a combination thereof is introduced into the blancher to heat the food product inside the blancher. In one preferred embodiment, steam and hot water comprise the heat transfer medium. During operation, food products are continuously or substantially continuously introduced into the blancher through the food product inlet, continuously or substantially continuously processed by the blancher, and thereafter continuously or substantially continuously discharged from the blancher through the food product outlet. As a result, a greater amount of food products can be more quickly heated to a desired temperature using a blancher of this invention as compared to a blancher that is not sealed and pressurized.
