Shard ice from ZIEGRA

Shard ice - supercooled ice around -7°C

• Ice thicknesses from 1.5 to 2.5 mm
• for fast and effective cooling
• for storage below 0°C
• A distinction must be made between rotating and stationary evaporators; the stationary evaporator avoids refrigerant leaks
• its robust design makes the machines extremely reliable

Shard ice is particularly suitable for cooling processes when used directly after production without prolonged intermediate storage.
 

How the Ziegra ice machines work:

The ice is produced in a vertical, fixed, double-walled cylinder. The water is pumped into a distributor ring and runs down the inside of the cylinder from there. Refrigerant circulates between the cylinder walls and cools the cylinder so that the water freezes on its surface. The resulting ice is chipped off the cylinder wall by a pick-up roller and falls into the ice container below.

As there are no rotating parts in the refrigeration circuit of the evaporator, no refrigerant seals are required and leaks are avoided.
Furthermore, the ice is harvested without touching the cylinder wall. As a result, the service life of the ice maker is correspondingly long.
