Focusun direct system block ice machine adopts edge-leading refrigeration industry technology. After direct heat exchange between refrigerant and water, in 5 to 8 hours, water is frozen out into ice. By that time, PLC controls the machine automatically into ice doffing process. Direct system utilizes hot Freon to defrost ice; so the defrosting process is fast. Aluminum evaporator adopts special technique to make sure the ice conforms to
