Continuous Vertical Vacuum Pan (CVVP)
Continuous Vertical Vacuum Pan" has multiple chambers with top mounted mechanical circulators. The feed, steam, vaccum, level and brix shall be controlled with respective automation. This pan design permits to boil with low temperature vapour to get the required output of Massecuite to save the steam.
At initial start up Seed/Grain/Magma and liquor shall be fed to the top chamber. Partly boiled Massecuite shall flow to the next down ward chamber by gravity with reference to the level in the first chamber. This process shall continue and the Massecuite shall flow in sequential order to the below chambers. Magma shall be continuously fed to the first chamber with reference to between magma and liquor. And liquor shall be fed to all working chambers with reference to the brix in the respective chambers. Final product (Massecuite) shall be taken out from the bottom chamber/final chamber.
Different pressure vapour for different chambers can be used from the evaporators so as to achieve the steam economy. Top mounted mechanical circulators shall improve the circulation, rate of crystallization and crystal yield.
Entrainment catchers shall be provided at the vapour outlet of each chamber. Modular compartment facilitates cleaning of any chamber, when the pan is in continuous operation. There shall be one single common condenser for all the chambers. The pan shall be provided with complete automation either with PLC or with DCS.
Salient feature of Continuous Vertical Vacuum Pan (CVVP)
