A refrigeration controllere for use with an apparatus for manufacturing soft-ice-cream and the like by beating and refrigerating at a preset temperature an ice-cream mix supplied from a hopper into refrigeration cylinders.The controller is adapted to monitor refrigeration time and refrigeration temperatures of the refrigeration cylinders and the hopper so that, in case refrigeration time becomes too long due to wrong temperature setting, the preset lower temperature limit is shifted up to correct the wrong temperature setting, thereby permitting a layman to control the apparatus and provide ice-cream having proper softness and at the same time save energy and the life-time of the apparatus.
