3. ICEMAKING MECHANISM
[a] EVAPORATOR (DRUM)
The Evaporator consists of an aluminum alloy cylinder with an icemaking surface on its exterior,
a press-fit plastic part with a refrigerant path, and a shaft for refrigerant supply and rotation. The
Evaporator penetrates the side of the Tank, and the Cutter scrapes off ice forming on the
Evaporator surface.
[b] CUTTER
The stainless steel Cutter is fixed on the Tank so that it can be repositioned against the Evaporator.
[c] BEARING
The Bearing is installed on one side of the Tank to support the Evaporator (Drum) Shaft. The
Gear Head provides the same function on the other side of the Tank where the Gear Motor is
located to drive the Drum.
[d] MECHANICAL SEAL
The Mechanical Seal prevents refrigerant leaks from the rotating Drum. The rotary ring attached
to the Shaft and the stationary ring fixed on the Housing form a carbon ring shaft sealing system.
