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.
