Widespread throughout the global food and drink industry, the use of flake ice | scale ice | nugget ice is a vital element in many processing operations. Ziegra ice machines are designed and manufactured to cater for the growing applications for flake | scale | nugget ice around the world. Each machine features integrated refrigeration, controls and ice maker. The result is a complete packaged unit that is easy to install, requiring just secure connection to utilities.

Sizes and view of ice available:

Type: Nugget ice (small cubes)

Temperature: - 0.5°C
Size:  small cubes

Widespread throughout the food and hospitality industry, nugget ice is a versatilie solution for many bars, restaurants and supermarket operations. Ziegra nugget ice machines are designed and manufactured to deliver a high quality and reliable product that will deliver hygienic ice for years. Use for food and drink displays, in drinks and for making cocktails.

  • fully frozen with high cooling capacity
  • softer than cubes or scale ice, protects the cutting blade
  • ideal for drinks and cocktails, easy to chew
  • best storage capabilities
  • protects goods, does not freeze them
  • Nugget ice is hygienic due to its closed water system
  • the static evaporator avoids refrigerant leaks
  • its robust design makes the machines extremely reliable.

Type: Flake ice (granular)

Temperature: - 0.5°C
Size:  small flakes

Like all other types of Ziegra flake ice, micro ice consists of irregular pieces of ice. In the case of micro ice, these pieces are  small, which means there is greater surface area contact with a given product and therefore the rate of cooling is increased. Micro ice is also gentle on delicate products.

Typical uses for micro ice are:

  • Dough cooling in bakeries
  • cooling meat during bowl chopping
  •  Immersion cooling processes (cook & chill)
  • Icing delicate products . e.g. herbs and prawns
  • Sample cooling in Laboratories

The small piece size of micro flake ice can be seen in the picture left. The ice held in a hand hopefully provides sufficient perspective, so it can easily be compared with our other ice types. You will find a similar image on the page for each ice type

Micro ice is very searching. When packing a product such as prawns the ice is added to the top, the box is then shaken and the ice finds its way between the product and into every nook and cranny.

Other types of flake ice would just sit on the top, leaving the product below unprotected.

Type: Flake ice (granular)

Temperature: - 0.5°C
Size: Medium flakes

Like all other types of Ziegra flake ice, midi ice consists of irregular granular pieces of ice. In the case of midi ice, these are wide ranging in size, with a mix of medium sized flakes, interspersed with much smaller pieces, making this ice a good general purpose ice and a good compromise between micro and macro ice sizes.

The size of the flakes can be seen in the picture on the left, where it is held in the hand.You will find images of ice in someones hand on each ice type page, which hopefully provides perspective, so that a direct comparison can be made with our  other ice types

Ice in storage bins can be kept for several days in a room at ambient temperature, but the ice will remains loose and friable. The most common application for midi ice is for the display of fish in retail outlets such as fishmongers, supermarkets and food service stations. It is also very popular for packing whole fish and fillets in processors. Where the ice is to be used for other things such as soft drinks, wine presentation etc, nuggett ice is probably a better option

Type: Flake ice (granular)

Temperature: - 0.5°C
Size:  large flakes

Like all other types of flake ice, macro ice consists of irregular chips or flakes of ice. In the case of macro ice, these flakes are very large and thick, making this the slowest melting of all the flake ice types.

Some typical uses for macro ice are:

  • Packing shellfish and other tough products
  • Long distance transport of perishable goods
  • Bulk packing/cooling of whole salmon/trout
  • Icing hides/skins
  • Packing vegetables

Large, thick flakes of Ziegra macro ice are  ideal  when the longevity of the ice is one of  the main  concerns.  It was originally developed for use in the warm  climates where the benefits of flake ice were  needed but with a larger flake for  maximum  storage life at higher ambient  temperatures. This has made it a very popular flake type for  applications with similar problems in the Central Asia..

 The ice is shown in someone's hand to give  perspective, when comparing with other Ziegra ice  types.

These images shows how large the flakes are compared to other types. This along with its optimum temperature gives macro ice exceptional storage characteristics. This ice will outlast any other flake type, it will never freeze together and its slightly curved shape means that it does not slide out of the door so readily when the bunker is opened, reducing a potential hazard

Type: Scale ice (flat thin pieces)

Temperature: - 5 | -7°C
Size: Different but same thickness

Scale ice is an extremely versatile product, with a number of diverse commercial applications, from the fishing industry to the construction sector.
It is much flatter and thinner than nugget ice and made by scale ice machines at a lower temperature, around -7℃, meaning it is actually cold enough refreeze its own meltwater.
To combat this, scale ice storage should always be maintained at a temperature below 0℃, to avoid the formation of jagged or fused lumps which are not fit for purpose.
As with StreamIce® systems, the output of scale ice machines can be altered and controlled by the introduction of salt.
Smaller flakes are produced via the use of just fresh water but the introduction of the appropriate salt levels can improve the quality and size of the ice. 

Ziegra designs and manufactures scale ice machines with up to 2,500kg capacity, specifically for installation on board fishing vessels. These are comprehensively tested to ensure optimum suitability for their setting, in terms of reliability, consistency and robustness in harsh conditions. Fish packing aside, scale ice machines are not recommended for applications where the ice will be mixed with food products. Larger scale ice machines up to 15,000kg capacity are available for use in heavy industry critical operations such as concrete cooling and reactor cooling.
