Behaviour of Ice Crystal Growth in a Vertical Finned Cylindrical Freeze Concentrator

Abstract:

Behaviours of ice crystal growth at two different operating parameters namely coolant temperature and circulation time were investigated for progressive freeze concentration (PFC) of glucose solution through a vertical finned crystallizer (VFC). Two determinant parameters which are ice production rate (m_u), and water recovery (W_R) were used to illustrate the behaviours of ice crystal growth in this study. From the result, higher ice production rate (m_u) and water recovery (W_R) were achieved at lower coolant temperature. On the other hand, longer circulation time resulted in lower ice production rate (m_u), but at the same time increased the water recovery (W_R). The maximum ice production rate (m_u) and water recovery (W_R) attained through this study were 1.522 gm^-2s^-1 and 51.131 %, respectively.
