- Such devices are used to produce from liquids, especially water, ice crystals.
- liquids especially water, ice crystals.
- the ice is called flake ice.
- the flake ice is used, for example, in the food industry for the production of food and for the freshness of food during transport and storage. In this way, you can
- flake ice at the Production of sausage used.
- other liquids such as juices, sauces, egg, milk and milk products can be processed to flake ice.
- flake ice made from different liquids is used in medicine, pharmacy and engineering.
- a device for the production of flake ice in which a cylindrical evaporator is rotatably mounted in a receiving the liquid to be frozen trough and is rotated by a drive about its longitudinal axis.
- the cylindrical evaporator is also called
- Evaporator roller called.
- refrigerant channels in the form of a helix extend along the inwardly facing side of the jacket of the evaporator roll.
- the refrigerant is supplied via a refrigerant supply extending in the evaporator roller refrigerant channels and discharged via a refrigerant discharge from the evaporator roller.
- the refrigerant evaporates, which leads to a cooling of the evaporator roller.
- a disadvantage proves that because of the rotatable evaporator roller for the refrigerant supply and the refrigerant discharge rotary feedthroughs are necessary. These are subject to the risk of leakage. In addition, wear causes the
- the invention is therefore based on the object to provide a device for producing ice, in particular flake ice, in which on rotary unions on the refrigerant supply and on the refrigerant
- the invention is achieved by a device having the features of claim 1.
- the device according to the invention is characterized in that it is arranged with a rotatable and by a drum drive for rotation powered electric drum, which is hollow inside.
- an evaporator In the interior of the Eistrommel an evaporator is arranged stationary. He does not turn with the ice drum.
- the evaporator has a refrigerant supply, a refrigerant discharge, and at least one refrigerant passage connecting the refrigerant supply and the refrigerant discharge, through which a refrigerant passage
- Refrigerant flows in the direction of propagation and evaporates.
- the level of the refrigerant channel is either substantially the same from the refrigerant supply to the refrigerant discharge or it changes continuously or stepwise in the always same direction.
- a refrigerant in the space between the evaporator and the interior of the surface of the Eistrommel ensures that the cold of the evaporator is transferred to the Eistrommel.
- Rotary feedthroughs at the refrigerant supply and at the refrigerant discharge must be equipped.
- the refrigerant channel is not in the form of a helix on the inwardly facing side of the Eistommel but with a constant level or with a level change in always the same direction. This means that the level of the refrigerant channel from the refrigerant supply to the refrigerant discharge
- the rise or fall of the level can be continuous, ie continuous or gradual.
- the refrigerant supply and the refrigerant discharge are connected to the refrigeration circuit of a refrigerator.
- refrigerant In the circulating in the refrigerant circuit refrigerant is always a certain proportion of lubricants that for Some components of the chiller are necessary. These lubricants do not affect the refrigeration cycle as long as they are carried by the refrigerant and do not settle in one or more places in the refrigeration cycle. This also applies to the refrigerant channel in the evaporator.
- a refrigerant channel with the course of a helix as in DE 195 07 864 A1 is possible in an evaporator driven for rotation.
- each turn forms a depression at its lowest level, in which lubricant can settle.
- lubricant can settle in the refrigerant channel of the evaporator, this leads to an undesirable reduction in the cooling capacity of the evaporator.
- the lubricants no longer circulate in the refrigeration cycle and therefore lack elsewhere in the refrigeration cycle.
- the refrigerant passage Due to the passage of the refrigerant passage from the refrigerant supply to the refrigerant discharge, the refrigerant passage is substantially free of sinks.
- the course of the refrigerant channel according to the invention has the advantage that no lubricants can settle in the refrigerant channel.
- the performance of the evaporator can thus be maintained over a long period of time.
- the level of the refrigerant channel in the propagation direction of the refrigerant from the refrigerant supply to the refrigerant discharge remains substantially the same.
- the level of the refrigerant channel decreases in the propagation direction of the refrigerant from the refrigerant supply to the refrigerant discharge substantially continuously or stepwise.
- the level of the refrigerant channel increases in the propagation direction of the refrigerant from the refrigerant supply to the refrigerant discharge substantially continuously or stepwise.
- the refrigerant channel has a plurality of first portions, which extend substantially parallel to the axis of rotation of the Eistommel.
- the first sections preferably have a straight course.
- the refrigerant channel has a plurality of second sections, wherein each second section connects two successive first sections of the refrigerant channel in the propagation direction of the refrigerant.
- the second sections may, for example, be curved sections. In such a course of the refrigerant passage, the refrigerant flows from the refrigerant supply to the refrigerant discharge several times parallel to the rotation axis of the Eistrommel back and forth.
- the refrigerant passage of the refrigerant supply substantially only once parallel to the axis of rotation of the Eistrommel through the evaporator, before he in the Refrigerant discharge opens. This process is sufficient for small ice drums with a correspondingly small evaporator.
- the refrigerant passage extends in one or more planes.
- the at least one plane can be aligned horizontally.
- the at least one plane may be inclined to the horizontal, typically at an angle of less than 10 °. If the refrigerant channel runs in several planes, these planes can be aligned parallel to one another. If multiple refrigerant channels are provided, each refrigerant channel can be in a separate
- the refrigerant channel is guided back and forth. It may have a plurality of mutually parallel sections in the plane which are parallel to the axis of rotation of the Eistommel or perpendicular to the axis of rotation or perpendicular to a parallel axis of rotation or under any other orientation.
- Channels in the plane are connected by curved connecting sections.
- the cross-sectional area of the refrigerant channel or the refrigerant channels increases
- the flow cross-section of the refrigerant increases in the propagation direction.
- This can be realized for example by the fact that the refrigerant channel is continuously or stepwise wider in the propagation direction or that a refrigerant channel is divided into several sections. Due to the volume increase during the transition of the refrigerant from the liquid to the vapor state, the flow velocity changes with a constant cross-sectional area of the refrigerant channel. By increasing the cross-sectional area of the refrigerant channel in the propagation direction, the flow velocity can be kept at least approximately constant. Alternatively, the
- the flow cross-section of the refrigerant channel or the refrigerant channels has thus influence on the flow dynamics, on the thermodynamics, on the pressure loss and thus on the cooling capacity of the evaporator to be transferred.
- the refrigerant channel is formed by a tube.
- the tube may have a circular, another round, for example oval, or an angular cross-section.
- the tube on its outer side on a surface magnifying structure.
- the tube can be equipped, for example, on its outside with grooves, with a corrugation, a cross corrugation or a pyramidal structure.
- additional elements such as fins may be provided on the tube.
- the lamellae can have a circular, spiral-shaped, arbitrarily curved or straight course.
- the refrigerant channel is formed by an extruded profile with micro or Minichannel.
- the micro or mini channel forms a channel in the extruded profile through which the refrigerant flows.
- the device is equipped with a circulation device for the brine. This ensures that the brine is set in motion. This improves the transfer of cold from the evaporator to the ice drum.
- the circulation device has a stirrer with at least one agitator shaft driven for rotation and stirrer blades arranged on the stirrer shaft.
- the stirring shaft extends in the interior of the ice drum preferably parallel or substantially parallel to the axis of rotation of the Eistrommel. She can too be arranged coaxially to the axis of rotation of the Eistommel.
- the stirring shaft can also be arranged at an angle greater than 0 ° to the axis of rotation of the Eistommel.
- R.erieln cup-like stirring elements can be arranged on the agitator shaft.
- the stirring shaft is connected to a stirring drive. This is preferred outside the
- Ice drum arranged.
- At least one baffle body is arranged on the agitator shaft. It ensures that the brine is directed towards the inside of the ice drum.
- Impact body may for example have a conical shape. It is arranged on the agitator shaft such that the axis of the cone extends along the axis of the agitator shaft. According to a further advantageous embodiment of the invention is in the
- Eist drum arranged at least one refrigerant volume-limiting device. This ensures that the brine does not fill the entire volume of the interior of the ice drum minus the evaporator but only a part of this volume.
- the refrigerant volume-limiting device may be, for example, a
- Displacement body act, which is located in the Eistrommel next to the evaporator.
- a chamber can be separated within the Eistommel, in which the refrigerant can not flow.

- the device is characterized in that it is equipped with an air line, which connects the interior of the Eistrommel with the environment of the Eistrommel. This air duct allows the interior of the ice drum to be ventilated and vented. Furthermore, the device is equipped with a brine line, via which a refrigerant can be introduced into the interior of the Eistrommel and derived from the interior of the Eistrommel. Bleeding is important to fill the ice drum with refrigerant. So that the brine fills a space provided between the evaporator and the inside of the ice drum for him, without air accumulates in this area in large quantities, it is important to vent the ice drum when filling the brine. In addition, it is important to aerate the ice drum to drain the brine out of the ice drum.

- the air duct has a first portion which extends parallel to the axis of rotation of the Eistrommel. Furthermore, the air duct has a second section, which extends in the interior of the Eistrommel substantially radially to the axis of rotation of the Eistommel. In this case, the first section can run through a fixed axis of the ice drum.
- the air duct extends to a surface facing the interior of the shell of the Eistrommel.
- the distance between one of the inside of the ice drum facing the open end of the air duct on the one hand and the inside of the ice drum on the other hand is so large that air can flow into the open end of the air duct and can flow out of the end of air.
- the air duct thus does not touch the inside of the ice drum with its open end.
- the air duct opens near the inside of the jacket of the Eistommel and on the upwardly facing side of the Eistommel in the interior of the Eistommel.
- the air duct is preferably oriented substantially vertically upwards so that the open end of the air duct, at which the air from the ice drum flows into the air duct and at which the air flows out of the air duct into the ice drum, located near the highest level of the Eistommel is. This is advantageous because air is lighter than the brine and therefore the air accumulates in the upper part of the ice drum. Also from this area, air can be removed from the ice drum with the air line.
- the air duct may have a straight or a curved course.
- the brine pipe has a first portion which is parallel to the axis of rotation of the Eistrommel.
