Title:
PROGRESSIVE FREEZE-CONCENTRATION SYSTEM
Document Type and Number:
Japanese Patent JP2015174067
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a progressive freeze-concentration system that can easily cut and transport ice crystals and is excellent in conservation of a solute in a molten liquid.SOLUTION: The progressive freeze-concentration system of the present invention comprises: an ice crystal generation part that generates hollow rod-shaped ice crystals n a vertical pipe by circulating a solution into the vertical pipe while the outside of the same is cooled by a coolant; an on-off valve that opens and closes the lower opening of the vertical pipe; an ice crystal crushing conveyor which is arranged below the vertical pipe, places and holds on the transport face thereof and transports the ice crystals naturally dropped from the vertical pipe and taken out by opening the open/close valve; and an ice crystal melting part that partially melts the transported ice crystals to obtain a molten liquid of desired concentration. The top of the transport face has salients arranged at predetermined intervals, and the ice crystals are cut one after another in a vicinity of the lower opening by hooking the lower end of the ice crystals naturally dropped from the lower opening on running salients.
