Mechanical Circulator

Circulation of massecuite in the pan while boiling play a prime role in proper growth of crystals and exhaustion of molasses. Mechanical agitator gives a marked improvement in the boiling and improves the quality of the product .it permits a valuable gain in purity of molasses and renders possible work with tighter massecuite. Correctly hydro dynamically designed propeller ensures the best fit calculations at lowest power consumption test. It provide the option of achieving an acceptable heat transfer with temperature difference as low as 20â°c, compare to at least 45-50â°c in the absence of stirrer. The use of low pressure vapour becomes possible, allowing reductions in the factory steam requirements. Mechanical agitator assembly consists of the following elements:-
â· an agitator carrying vanes or other propelling means
â· a driving system connected with the shaft. The driving system usually consists of the shaft,
coupling, bearings, gearing, pulleys and belts. The power is supplied by an electric motor
a. Advantages:-
â· saving in strike time of up to 30%.
â· good circulation maintained through the strike.
â· provide more uniform grain.
â· increased pan capacity by 20-30%.increase in crystal yield up to 5%.
â· the color removal has improved from 88% without agitator to 92% with agitator.
â· sugar conglomerates counts have been reduced by about 80%.
â· strike level in pans can be raised by 30-40 cm with the use of stirrer.
