Industrial Ice Machine


Industrial Ice Machine with half the energy costs compared to conventional drum systems

Above all, an Industrial Ice Machine BUCO manufactures at half the the energy costs, compared to all drum systems. Ice is manufactured at a favorable evaporation temperature of -8°C to -10°C. Compared to the conventional drum systems, which operate in between -20°C to -35°C, our Industrial Ice Machines only consume half the electric energy for refrigeration and have a COP value twice as favorable as drum ice systems.

For the best possible quality of certain foods, you need cooling through dull ice, without freezer burn on the direct product surface, and with customizable ice thickness. In the first place, with our  Industrial Plate Ice or Chip Ice Machine, you do not only get the fastest possible product cooling, but also a continuous cooling.
With our Industrial Ice Machines an exact ice dosage can be guaranteed, which is necessary for the cooling of high performance cutters, f.e. during sausage processing or mixing processes. Our Industrial Ice Machine meets high demands on easy cleaning and energy efficiency. Consequently they are also adapted to the respective strict requirements in food processing.

Function of an Industrial Ice Machine

The units operate with vertical, water-sprinkled evaporator plates and cyclic hot gas defrosting.
The ice freezes on the vertical stainless steel evaporator plates to a thin layer, which keeps the thermal resistance always low. After a few minutes of ice formation is defrosted via automatic control for a few seconds with hot gas. In the case of the fall, the ice breaks up into roughly hand-sized pieces, which are separated from the water on a suction slide and then crushed in a rotating icebreaker. Later the crushed ice or chip ice falls down the full length of the Industrial Ice Machine and is available for transport with a conveyor belt or auger in the ice factory or industrial food processing.

Both the ice thickness and the piece sizes can be adjusted continuously. Our Industrial Chip Ice Machine gives you the maximum power reserve and safety in production. In addition, there are only a few moving parts, which increases operational reliability and minimizes maintenance. A crusher systems breaks the falling ice chips from the Industrial Ice Machine in adjustable ice chips with thickness in between 4mm to 12mm. Ice Storage systems can be adjusted.

Energy consumption advantage of an Industrial Ice Machine

It is possible to use a simple defrosting device which, due to the hot gas supply of large central refrigeration plants, requires fewer refrigerant valves and a simple control system. To produce ice, we do have the efficiency in prior focus. Only by melting of the ice, the heat for cooling of the water is taken from the surrounding. Ice is melting at a temperature of 0°C to water and gives 335 kj per kg ice.

Therefor we do produce ice with an evaporation temperature T0= -10°C, which generates ice at a temperatures of  T= -0.5°C to -1.0°C. The idea is simple, as the cooling gain for subcooling of the Flake Ice in conventional drum systems is down to T= –8°C, which is only approx. 8% of a higher melting capacity. Unfortunately this has a high energy consumption impact for the drum ice machines as such:

Highest cooling capacity with minimum energy input 335 kj/kg ice at 0°C !

Highest cooling capacity with minimum energy input 335 kj/kg ice at 0°C !
