DEVICE FOR MOULDING GRAINS FROM SOLUTIONS AND SUSPENSIONS OF FOOD SUBSTANCES

摘要

The present invention relates to food industry equipment. It is particularly adapted for use in the production of granulated food products, preferably imitation soft caviar. The device is provided with a heated chamber for keeping said solutions or suspensions under pressure, which has through holes drilled along a concentrical circumference in the chamber bottom. Tightly pressed to the bottom from inside is a revolving disk with through holes that are to match the holes in the chamber bottom during rotation of the disk. A vessel is installed under said chamber to contain a forming liquid and to form granules from the solutions or the suspensions fed into the vessel via the holes in the bottom of said chamber. This vessel is cooled and accommodates a pipe for feeding the forming liquid to the vessel and a pipe for taking it out of the vessel together with formed granules. This vessel jointed to the chamber bottom through a heat-insulating spacer with nozzles coaxial with the holes in the bottom is actually a tubular heat exchanger, whose tubes communicate with the holes in the chamber bottom via the nozzles. Each nozzle concentrically protrudes from the spacer into the upper end of the respective tube with an annular gap allowing the tubes to communicate with each other and with the forming liquid feeding pipe. The granules forming device of this design makes it possible to retain the food value of formed granules and to raise the efficiency of the device considerably.
