Abstract: A door seal arrangement and method for sealing between a door and a door frame on food processing equipment are provided. The door seal is inflatable to create a seal between the door and the door frame and deflatable to release the seal between the door and the door frame. An air supply applies positive air pressure to the door seal to inflate the door seal. A vacuum applies a negative air pressure to the door seal to deflate the door seal.

Abstract: Apparatus and methods for pasteurizing food product are provided. The apparatus includes a cabinet enclosing the food product as it is transported from upstream to downstream through a series of processing zones including a pre-condensing zone, a pre-heating zone, a pasteurizing zone, a post-heating zone, and a post-condensing zone. In use, the food product is conveyed through the series of processing zones, which together function to efficiently and effectively heat and apply pasteurizing steam to the surfaces of the product to kill bacteria, while at the same time managing migration of steam from the pasteurizing zone and preventing steam from migrating out of the cabinet into the surrounding area.
