Abstract: A device and a method used when coating a wafer is described. The fluid coating is provided by an inside coating as well as an edge coating. The fluid chocolate in a container is stirred by displacing a vat up and down. During this displacement, the vat will be brought in contact with the wafer, so the chocolate substance, which is provided in there, provides an edge coating. Displacement of the first vat provides a repression of the chocolate substance, which through a nozzle is injected into the wafer in order to provide an inside coating. By repression, a pumping occurs, which is interrupted substantially simultaneously with the edge of the wafer getting in contact with the surface of the chocolate in vat, when it is elevated up towards the wafer, which is suspended in a commonly known apron conveyor (not shown).

Abstract: The invention comprises a slat conveyor for handling ice cream products (6) which are immersed for some time in processing vessels. Each slat (9) in the conveyor consists of an upper part (33) supported at a fixed height in the frame (40) of the machine and a lower part (34) that may be lifted and lowered by means of a lifting beam (41). The lower part (34) of the slat is supported by individually coupling and uncoupling means (44, 48). The means (44) are connected with the lifting beam (41) and the means (48) are connected with the frame. By activating and deactivating the means (44, 48) together with the lifting beam (41) it is possible to keep the products (6) in a raised position or in a lowered position throughout one or more successive operations. Hereby the process period may easily be varied and the slat conveyor can readily be adapted to different products just by changing the programming of the control unit for the coupling means (44, 48) and the lifting beam (41).
