TH11709B - Air-operated machines for food, with a prop in the opposite direction to the feed direction, at least occasionally. - Google Patents

Abstract

A machine operating air, such as a food freezing unit consisting of a chamber (1), a long rail (12) arranged inside to accommodate food to be processed, a heat exchanger (13) and a fan system (14). ) To cause air to flow around the heat exchanger, up through the trough and back to the heat exchanger, the bottom of the rail is porous (16). This belt (16) is driven by an electric motor with a control unit. At least occasionally in the opposite direction to the passage of the feed feed in the rail (12).

Claims (9)
