Broken ice from ZIEGRA

Broken ice - the modern ice cream

Also known as flake ice, it has the following properties
 

• different ice sizes: MacroIce, StandardIce, MicroIce
• ideal for quick and long-lasting cooling
• prevents frostbite or damage to your product
• always easy to work with, no freezing or clumping of the ice cream
• suitable for days of storage (in insulated ice storage units or containers)
• with high cooling capacity and energy efficiency
• BruchEis is particularly hygienic thanks to a closed water system
• the closed refrigeration circuit prevents refrigerant leaks
• the robust design makes the machines extremely reliable and durable

The ZIEGRA method of operation
 

Water flows from the water reservoir of the ice machine into the cylinder of the ice maker according to the principle of communicating pipes. A cooling coil (e.g. R452A) is placed around the cylinder, which freezes the water on the inside of the cylinder. The ice iscontinuously peeled off by the screwin a very thin layer of ice from the inside wall of the cylinder and conveyed upwards. There the ice is pressed hard, refrozen and then broken.

This process allows the cold energy to refreeze the following water immediately without loss. (If the ice layer were 1 or 2 mm thick, an unnecessarily large amount of energy would have to be used for freezing due to the high insulating capacity of ice). The idea of subsequently compacting and pressing the ice means that an ideal ice thickness of up to 9.5 mm can be achieved with low energy requirements. 

As the ice is frozen on the inside wall of the cylinder, the refrigeration system of the ZIEGRA crushed ice machines is completely closed. No leaks can occur in the refrigeration system due to rotating parts. Thanks to the patented cylinder process and ZIEGRA know-how, small compressors can be used.

This has the advantage of lower power consumption.
