Ice cream maker

An ice machine is a device for making ice cream, for cooling purposes in the broader sense also for making ice cubes and ice.

Ice-cream

With an ice cream maker ice cream is made. He is mentioned as a great technical equipment and Freezer. In addition to the freezing of the freezer the initial liquid, the so-called mix, air continues to be, the so-called premium or overrun. The heat is removed from the mix, with a cold engine. The heart of the freezer is a double-walled cylinder whose shell forms the evaporator of the refrigerator and the interior of which receives the enriched air mix. The anfrierende on the cylinder wall of ice is scraped from the so-called shock wave, a close-clearance stirrer.

Ice machines for domestic use is also available in a variant in which the ice mixture, the heat is removed by a cooling pack, which has previously been pre-cooled in the freezer of a refrigerator or freezer. It is driven by a crank or an electric motor. Ice machines are also available as accessories for kitchen appliances such as KitchenAid. Icemaker that will bring only the stirring must be placed in the freezer.

Lollies or ice lolly is made in two ways. In the so-called round freezer still pumpable ice is pressed into molds and inserted the stem from the top. The forms are driven by a cooling liquid brine to make hard ice. The second type of preparation is the extrusion. In this case, the stem is inserted into the extruded Eisstrang and cut the strand. Coatings are applied by quickly dipping them in the melted coating, such as chocolate.

Ice cream cakes are crafted from layered pumpable ice, decorated and then frozen.

Ice for cooling purposes

Flake ice

Flake ice produce granular, pourable ice that is used for different cooling processes, for example in food production, are used. It is approximately 1-2 mm thick, up to -7 ° C cold sheets of ice that form on a roller which is also the evaporator of a refrigerating machine.

Flake ice is used for the production of boiled and cooked sausage and bread dough. The fish counters in supermarkets are often filled with flake. On or in the bed of ice to fish and seafood can be transported chilled or even present attractive for sale. Flake ice can be handled with a chute and dose. In cool storage, it remains free flowing. It is also suitable for many other applications, eg at cold buffets, in the food industry for the product presentation and on fishing vessels to keep fresh the fish.

Ice

Ice maker make ice cubes ago ( " ice " ) of defined size, which are used for example for iced drinks. They consist of a refrigerating machine with switchable refrigerant circuit in order to begin to defrost the frozen- pieces periodically and separated as can. The pieces of ice form around pins or cooled in chilled bowls, which are open, sprinkled down with water.

The periodic heating dissolves the ice cubes and drops them into a storage container. For this, the refrigerant circuit with valves is switched so that the otherwise cooling evaporator briefly works as a condenser and heated therefore.

Historic ice factories

Prior to the distribution of electrical household refrigerators they used refrigerators for storing food to be cooled. They needed a few pound block of ice, a few days to stay cool. The blocks of ice were produced centrally in ice factories with large ammonia refrigeration machines and delivered to customers in buckets provided. See also Eismann.
