Said outer plate section (10) comprises a top subsection (11) extending in a first plane and wherein said inner plate section (20) comprises a top subsection (21) extending in a second plane, said second plane being offset, in an inward direction (A), with regard to said first plane. Said outer plate section (10) further comprises a bottom subsection (12) arranged in a bottom part of said outer plate section (10) and extending in a third plane being offset in said inward direction (A) with regard to said first plane.

Abstract: A supporting installation for supporting a number of turns extending helically one above the other in a belt pile and included in an at least partly self-supporting conveyor belt (2), comprising an inner supporting structure (8) which, together with an inner chain (5) supported by and movable along the same, defines an inner channel (12), in which one or more inner bearing elements (14) are arranged. Outer supporting structure (9) which, together with an outer chain (6) supported by and movable along the same, defines an outer channel (13), in which one or more outer bearing elements (15) are arranged. The installation is characterised in that each chain (5; 6) comprises abutment surfaces which form a radially outer side wall (23) of the inner channel (12) and the outer channel (13) respectively, and that the outer bearing elements (15) are arranged for transfer of radially inward forces from the outer chain (6) to the outer supporting structure (9).

Abstract: A supporting installation (1) for supporting a number of turns, extending helically one upon the other in a stack, of an at least partly self-supporting conveyor belt (2) comprises at least one bearing element (9) for supporting the conveyor belt (2), and a section (4) for supporting the bearing element (9). The section (4) is extended in an endless loop along which the bearing element (9) is movable. At least one bearing element (9) is a roller bearing element (10).

Abstract: An endless conveyor belt for an air conditioning plant, in which the conveyor belt extends helically along part of its length, comprising transverse rods (4) and lateral elements (3). The conveyor belt is characterized in that the lateral elements (3) are connected in pairs to only two rods (4), which are fixedly connected to said lateral elements (3) and form, with these, a link means (2), and adjoining link means (2) are articulated to each other by a coupling element (5) arranged therebetween and connected to neighboring rods (4) of the adjoining link means (2).

Abstract: A food product is frozen at least partially by contacting a surface area (4) of a chilled tray (1). The tray (1) consists of a plurality of elements (2, 3). The elements are juxtaposed to form the surface area (4), they are further movable relative to each other for changing of the relative position of at least one element at a time, and finally they each occupy such a small surface in the surface area that the change of relative position is possible also after the food product part contacting the tray has been frozen.

Abstract: An apparatus for gas treatment of products rises a housing having top, bottom and side walls; a conveyor belt for transporting the products along a first path in the housing; a tunnel having perforated walls and enclosing the conveyor belt along the first path; a gas circulation device communicating with the tunnel via the perforated walls for circulating gas into the tunnel in the form of gas jets impinging upon the products carried by the conveyor belt, and out of the tunnel in a return channel back to the gas circulation device; and a gas conditioning device positioned in the return channel. At least one substantially vertical part of the connecting walls of the high-pressure chamber is removable so as to provide access to the inside of the pressure chamber, and at least one of the side walls of the housing along the high-pressure chamber may be movable so as to widen the space between at least one wall and the high-pressure chamber.

Abstract: A method and apparatus for freezing a surface layer of food product (6), placed on a non-foraminous conveyor belt (7) wherein cold air in the form of jets is blown towards the underside of the non-foraminous conveyor belt. The apparatus for carrying out the method comprises, in addition to the non-foraminous conveyor belt (7), a plurality of stationary nozzles (14) for producing jets towards the underside of the non-foraminous conveyor belt in an area which extends over the width of the non-foraminous conveyor belt.

Abstract: A conveyor belt washer having a plurality of nozzles (12) for ejecting water jets towards an upper side of a foraminous conveyor belt (5). A tank (2) is positioned under the foraminous conveyor belt for receiving water ejected from the nozzles, the tank having a foraminous top side (17) for separating particles accompanying the water, an outlet opening (16) in a lower part (9) thereof and a ventilating opening in an upper part (8) thereof. The conveyor belt washer further having a pump (24) with an inlet and an outlet (29), and pipings (27, 28) connecting the outlet opening of the tank to the inlet of the pump, and the outlet of the pump to the plurality of nozzles, such that the water is recirculated and air entrained by the water through the foraminous top side of the tank escapes through the ventilating opening thereof.
