Abstract: A processing apparatus for viscous materials comprises a vertically disposed annular space. The materials to be processed are fed in at the bottom of the annular space and the processed materials are removed at the top. A vertically disposed rotating shaft and a multiplicity of essentially radial arms which are attached to the shaft and to the ends of which vertical components are attached. The vertical components travel around in the annular space as the shaft rotates, so that the inlet of the materials to be processed debouches tangentially into an annular chamber beneath the annular space. The width of the annular chamber is greater than the width of the inlet and is greater that the width of the annular space.

Abstract: Equipment for continuously coagulating preferably preacidified milk for preparing yoghurt, provided with means for keeping the milk at a desired temperature during coagulation, with means for feeding in the milk and with means for discharging the yoghurt, whereby the equipment consists of an essentially closed housing containing an endless conveyor belt on which containers of the paternoster-lift type are suspended, provided with means for advancing the conveyor belt at uniform velocity in the housing at a velocity such that each container remains for a desired time in the housing, and with means for stopping each container stepwise outside the housing during filling and during emptying.

Abstract: An installation for the pasteurization or sterilization of products packed in containers comprises a treatment space with a conveyor travelling through this space and having carriers for supporting the containers. The conveyor passes along a loading and a discharging station. Each carrier has a plurality of equally spaced partitions to define a number of compartments. A supply conveyor at the loading station has driving dogs spaced from each other equal to the distance between the carrier partitions. A discharge device is provided with the same number of tiltable catching elements as there are compartments in each carrier.
