Title: Method and device for storing cheese
IPC: A01J25/16
Filed: 1974-08-13
Abstract: 1459549 Storing cheese KOOPMANS ENG BV 13 Aug 1974 [20 Aug 1973] 35613/74 Heading A2D  A method of storing cheese comprises arranging the units of cheese in a stand in a plurality of layers on boards located side by side and turning over the cheese by displacing a layer of boards transversely of the direction of length of the boards over a distance approximately equal to the width of one board so that the board carrying the cheese is moved to a position outside the stand, after which an empty board is put down on top of the cheese so removed, the two boards with the cheese sandwiched therebetween being turned through 180‹ and being moved to the level of a new layer located at a different height to that of the layer of the initially displaced board, the board laden with cheese being then slipped into the stand at the level of the new layer. An apparatus suitable for carrying out the above method is shown in Fig. 1 and comprises a plurality of vertical columns 1 to which channel-section beams 2 are secured. These beams support the ends of boards 3 (Fig. 2, not shown) on which cheeses can be put down. There is also provided lifting devices 5 and 6, the latter being combined with a tilting device 7. The lifting devices, which are vertically displaceable along vertical guide shafts 9, comprise horizontal, pneumatic setting cylinders 8. The lifting devices are coupled to each other so that they are always at the same level. By means of the setting cylinders 8, all boards on a level will be shifted to the right a distance approximately equal to the width of a board and consequently, a board at the right-hand end of the stand will be shifted into the combined lifting- tilting device 6, 7. In this device, the cheese is rotated through 180‹ and raised to the next level. The boards in this next level are then shifted across to the left through a distance of approximately one board width, and the board on the left of the stand is pushed into lifting device 5. The lifting devices are then moved to the original level of the boards and the cycle can then be repeated. The method and apparatus are particularly applicable to the storage of Edam cheese.
