After that the extract is drained into the tank 117 and then fed into the second and thrid, along the travel path of the granules, vessels of the device 15 at 46 C with the aid of the feed-control pump 103 via the heat exchanger 118.
  • the length of travel of the granules-filled shells 73 in the tanning solution ensures the tanning of granules 0.2 m/min.

  • This solution is prepared in the tank 119 and intended for dying granules to make them grayish.
  • the preset concentration of said solutions in the vessels 71 is maintained, as the shells 73 are passing through them, by adding definite quantities of fresh portions of the solutions by means of dosing pump 103.
  • vessel 71 is filled with a concentrated sodium chloride solution cooled down to 46C. Salting of granules in this solution takes 2.5 to 3 minutes.
  • the sodium chloride solution is prepared in the tank 120 and supplied regularly to the seventh vessel to maintain its concentration in both the vessel and the system 106 of its circulation.
  • the discharging of the shells 73 is also carried out in the above seventh vessel by taking granules therefrom to the vdrain con veyer 17 with the aid of the sodium chloride solution circulating in the system 106 and fed to said vessel by the pump 111 via theheat exchanger 114.
  • the pump 111 helps maintain the level of the sodium chloride solution in the vessel 71 above the level of its escape from the pipe 16. As a result, the 'salt solution penetrates into the inside of the shells 73 available in the vessel, through the punched walls of said shells.
  • the solution picks up granules available therein and carries them along the radial channels into the central hole 87 of the disk 85.
  • the solution carrying granules is fed through the pipe 91 to the pipe 16 (FIG. 1) and poured, together with granules, onto the drain conveyer 17.
  • the provision of the conveyer 72 combining the vessels 71, in the device 15 for treating granules enables continuous treatment of granules in water solutions of various substances by way of the granules-filled shells 73 of the conveyer 72 passing, in succession, through all the vessels 71.
  • the drain conveyer 17 is the place where the sodium chloride solution as well as the moisture emerging from granules due to salting are separated from said granules.
  • the meshed draper 95 of the conveyer 17 the above liquids flow off into the collector 108 of the system 106 of the salt solution circulation, while the tanned, dyed and salted granules roll off the meshed draper 95 of the conveyer 17 into the hopper 99 that channels them into the device 18 for mixing with taste and aroma substances.
  • air is supplied from the blast blower 97 into the pipe 97, whose jet blows off granules stuck to the draper 95 into the hopper 99.
  • granules are fed through a port (not shown) in a face wall of the rotating drum (not shown). Supplied in the same way into the drum from the measuring devices 100 and 101 are dry and liquid substances being mixed with the granules during the drums rotation. The mixing of said granules with taste and aroma substances is best assisted by the inner longitudinal ribs of the above drum. As the latter is sloped, the granules being mixed move along the drum and escape from it through'the open face as soft caviar ready for packaging.
  • An installation for the production of granulated products from food substances comprising in combination:
  • means for controlling the feed of the food substance in liquid form connected in series with said means for preparing the food substance in liquid form;
  • a means for forming granules of the food substance in liquid form in a forming liquid connected in series with said means for controlling the feed of the food substance in liquid form;
  • a means for sorting said granules according to size connected in series with said means for separating said granules from said forming liquid;
  • a means for mixing said granules with taste and aroma substances connected in series with said means for continuously treating the granules with water solutions.
  • said means for controlling the feed of the food substance in liquid form comprises:
  • holes in said disk arranged along a concentrical circumference matching in succession with the holes in said bottom of said chamber during rotation of the disk at the moment of feeding the food substance in liquid form into the forming liquid, said holes in the disk being directed at an angle to an axis of rotation and the outlets of the holes extending from the axis of rotation.
  • holes in said disk arranged along a concentrical circumference matching in succession with the holes in said bottom of said chamber duringrotation of the disk at the moment of feeding the food substance in liquid form into the forming liquid, said holes in the disk being directed at an angle to an axis of rotation and the outlets of the holes extending from the axis of rotation.
