A working outline<br />
A fixed vertical evaporator (1) is cooled by the refrigerant fluid evaporating on the inside.<br />
Water is evenly distributed from<br />
above onto the internal surface (2), 2<br />
4<br />
where it freezes once it comes into<br />
1<br />
contact with the cold wall. A<br />
helicoidal ice-breaker (3) is<br />
positioned parallel to the cylinder<br />
axis, almost in contact with the<br />
internal surface and the gear<br />
reducer (4) causes the central shaft<br />
(5) to turn at a constant speed. The<br />
ice-breaker is connected to the<br />
3<br />
central shaft with a satellite<br />
mechanism.<br />
The ice-breaker rotates on the<br />
5<br />
surface of ice; it removes it by<br />
8<br />
breaking it into flakes which then<br />
fall by gravity. A flat, vertical blade<br />
(6) follows the ice-breaker cleaning<br />
the surface of possible residue.<br />
Un-frozen water is returned to the<br />
reservoir (7).<br />
6<br />
Water pump (8) circulates water<br />
around the system.<br />
