Embodiment Construction
[0018] Description of the preferred embodiment
[0019] With reference to Fig. 1 and Fig. 2, be used for food, as the fast cooling device of patty, comprise a shell 1, this shell 1 has a top wall 2, a bottom wall 3, two side walls 4 and 5, and two end walls (not shown). The top wall is supported on a strut 6 . Each of the side walls 4 and 5 has two parts 4a, 4b and 5a, 5b respectively. Each of these side walls 4a, 4b and 5a, 5b is movable by being supported on two telescopic arms 7 mounted on top of the top wall.
[0020] The side walls 4 and 5 are shown in Figure 1 in an expanded or open position, and in Figure 2 the side walls 4 and 5 are shown in a retracted and closed position. It is clear that moving one or both of the side walls 4 and 5 by pushing them from their closed position to their open position provides good access to the equipment in the housing 1 . On the other hand, when the side walls 4 and 5 are pushed back to their closed position as shown in Figure 2, t...

An apparatus for gas treatment of products comprises 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; gas circulation means 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 means; and gas conditioning means positioned in the return channel for conditioning the gas circulated by the gas circulation means. Walls connecting with the perforated walls of the tunnel and having an opening towards the gas circulation means form a high-pressure chamber substantially above the tunnel and spaced from the walls of the housing. 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. Further, 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 said at least one wall and the high-pressure chamber.
Description
Background of the invention [0001] The invention relates to the gas treatment of products, in particular food and similar products, such as cooling, heating or drying, by means of a gas jet directed onto the product. [0002] Apparatus for cooling or heating foodstuffs is known, for example, from US Patent 4679542 to Donald P. Smith et al. These devices consist of a housing in which a high pressure gas plenum is associated with upper and lower channels defining a treatment area therebetween and having a number of nozzles for directing gas jets into the treatment area middle. The food to be processed is supported by a conveyor belt that transports the food through the processing space. [0003] The design of these known devices is very complex, making it difficult to meet the high hygiene requirements of the food industry. Additionally, maintenance of prior art installations is time consuming, with short intervals between successive shutdowns. [0004] Another device for co...
