The purpose of the project is to intensify the sucrose crystallization process and create effective equipment for its implementation.
The hardware design improvement of the industrial sucrose crystallization
process' ways are determined by the conducted researches, also polythermal
crystallization modeling is carried out in mixers-crystallizers' sugar massecuite
boiling process. It is established that the initial syrup in the vacuum apparatus should be within 29-30% of the useful vacuum apparatus’ volume. The influence of the nutrient solution supplying at the vacuum apparatus’ method is revealed by the sucrose crystallization efficiency. It is experimentally proved that in the polythermal crystallization conditions the intermediate heating use (instead of dilution with water or molasses) of the last degree of crystallization massecuite after cooling to 50-55 ° C at 7-10 ° C at a rate of 1 ° C/min increases the overall polythermal crystallization effect up to 8.4%. It has been found that the massecuite heating by 7-10 °C reduces of the intercrystalline solution viscosity by almost 2 times. Matching the massecuite cooling rate with the sucrose crystallization rate depending on its frequency minimizes secondary crystal formation. On the basis of the performed researches the following are offered: new designs of vacuum devices; a new efficient polythermal sucrose crystallization method, as well as a new design of the massecuite heater for its intermediate heating. The results of the performed research were used by «Uk.Az.-Druzhba» LLC, «Yahotyn Mechanical Plant» LLC and «Eurosucor» PE.
