Abstract
A device for fruit and vegetable phase-temperature precooling compatible multi-coupling anti-aging treatment comprises a refrigeration house with a plurality of differential pressure precooling devices placed therein. The differential pressure precooling device comprises a hermetic seal tunnel precooling box, a separator plate is fixedly mounted at an upper part inside the tunnel precooling box and in parallel to a top wall of the tunnel precooling box with a space formed therebetween; the separator plate extends to the bottom of the tunnel precooling box; a venting plate is fixedly mounted to one side of the separator plate and in parallel to a side wall of the tunnel precooling box with a space formed therebetween; a section of wind shield is vertically and downwardly mounted to an end of the other side of the separator plate; an axial flow fan is mounted at a corner of the tunnel precooling box between the separator plate and the venting plate.
