Perforated walls and duct system

摘要

Apparatus for processing meat products in a controlled environment, in which chambers are arranged in pairs, side by side with one another, and defined by outside walls, and a common median wall, with meat support means arranged on facing surfaces of the walls and having air ducts provided in the walls and openings provided over the extent of the inside surfaces of the walls whereby air may flow from side to side across the chambers and air supply ducts connected to distribution ducts in the walls, and a fan for forcing air therearound, and means whereby flow through the various ducts may be reversed at periodic intervals so that air flow will take place across the chambers in opposite directions, reversing at predetermined intervals during the treatment. Also disclosed is a wall structure for such chambers in which the walls are divided up into a plurality of separate zones, at least some zones being provided with separate branch air ducts, and air connector ducts connected with the branch ducts, and with the other zones, all of which are so controlled, i.e. by dampers, that air flow volumes are substantially equalized over the entire extent of each wall surface.
