Abstract
A method of continuous production of ice-solution suspension wherein the solution being continuously fed (7) to the processing zone (6) is overcooled: then, the turbulization (14) is performed in the overcooled solution; as a result, ice microcrystalls are formed in the solution; after that, the formed ice-solution suspension is removed (8) from the processing zone, in doing this, the said turbulization is chosen with such intensity that the formed ice microcrystalls mass transfer balance will be positive, considering their adhesion on the internal surfaces in processing zone. An installation (1) for continuous production of ice-solution suspension is also described.
Claims3
An ice generator device for continuous production of ice-solution suspension comprising:
- a channel having an inlet for solution feed and an outlet for ice-solution suspension leaving;
- a cooling element having a cooling surface intended for interaction with the solution;
- a means for removal of the formed overcooled solution from the area of its direct thermal contact with the cooling surface, and
- means for solution turbulization of the overcooled solution, wherein the intensity of the turbulization is such that a positive mass transfer balance results,
- wherein the channel wall surface serves as a cooling surface;
- the channel has a cylindrical form;
- the means for solution turbulization is a hollow rotor placed coaxially to the channel and perforated by holes intended for passing the solution into the rotor hollow and back;
- and means for removal of the formed overcooled solution from the area of the direct thermal contact is guiding blades attached to the rotor, which are placed in said area inclined from a radial direction towards the rotor rotation side.
