Definitions
- the invention is based on a device for producing flake ice and on a method for cleaning a device for producing flake ice.
- Devices for producing flake ice serve to produce ice in the form of thin leaflets from liquids, in particular from water. Due to the shape of the pieces of ice, 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
- flake ice is used in the production of sausages.
- other liquids such as juices, sauces, egg, milk and dairy products can too Flake ice be processed.
- flake ice made from different liquids is used in medicine, pharmacy and engineering.
- Flake ice places particularly high requirements with regard to hygiene.
- all surfaces coming into contact with the flake ice of dirt, impurities, lime and pathogens, in particular bacteria, viruses, fungi and protozoa are to be freed.
- the device should be thoroughly cleaned at regular intervals and descaled and disinfected if necessary. Particularly important is the cleaning of the tub, in which there is a supply of liquid during operation of the device and possibly also during the periods between commissioning. Germs can multiply unhindered in this liquid supply. The regular emptying of the tub is not enough to reliably rid the surfaces of pathogens and fungi.
- the cleaning device has a plurality of spray nozzles for spraying the evaporator roller and the tub with a cleaning agent.
- a disadvantage here proves that the tub already in the production of flake ice machine with special
- Spray nozzles must be equipped so that a retrofit of existing machines is not possible. Furthermore, spray nozzles must be arranged in the tub in terms of their number and the orientation of their Sprühkegel so that a reliable cleaning of the tub, the evaporator roller and other takes place with the freezing liquid in contact parts. This leads to a high expenditure in the

Furthermore, the retrofitting of existing devices should be possible.
- a cleaning device for cleaning, descaling and / or disinfecting is provided, which is equipped with an additional circulation device.
- the circulation device has a drive. This is preferably a separate from the drive of the evaporator roller and independent drive.
- the circulation device generates in a cleaning liquid in the tub a flow which assists the removal and flushing out of impurities, lime and pathogens from the device. This is a flow that can be variable depending on the power of the drive. She is stronger than the one through the

- Contacting surfaces can not dry due to the bath of cleaning liquid contained in the tub. Thanks to the circulation of the cleaning liquid maintained by the circulation device, a homogeneous distribution of the cleaning liquid in the tub is achieved. In addition, a sufficient amount of cleaning fluid is always available at all points of the device to be cleaned during the entire cleaning process. Furthermore, the flow supports the removal of dirt, bacteria and lime by the mechanical interaction between the cleaning liquid and the respective surfaces of the device.
- cleaning liquid water or a mixture of water and detergent can be used.
- the cleaning agents used are, for example, agents which contain citric acid, acetic acid or chlorine compounds. From the cleaning liquid and the cleaning agent depends on whether a cleaning of the device with descaling and disinfecting or only one
- the cleaning fluid is introduced into the tub.
- a feed opening into the tub serves. This can either be an inlet for the liquid to be frozen or an additional inlet, which alone serves to supply the cleaning liquid.
- the inlet can open from above or laterally into the trough. In contrast to the state of the art Technique known cleaning nozzles this case meets an inlet to which no special requirements are made in terms of the direction of the exiting cleaning fluid and the opening angle.
- the cleaning liquid is drained from the tub. Following this, the tub can be filled one or more times with fresh water and the fresh water can then be emptied. This ensures that no residues of the cleaning fluid and no dirt particles, lime particles or bacteria remain in the tub and can get into the ice in the subsequent production of flake ice.
- the circulation device can be actuated in order to set the fresh water in flow. This additionally aids flushing out of cleaning fluid as well as dirt, impurities, lime and pathogens.
- the circulation device is decoupled from the inlet of the liquid to be frozen.
- the cleaning liquid flowing in the trough is completely separate from the inflow of the liquid to be frozen, through which the trough is filled with the liquid to be frozen during operation. This avoids that the cleaning liquid flows into the inlet for the liquid to be frozen and can lead to contamination of the liquid to be frozen. An additional system separation between the circulation of the cleaning liquid and the inlet of the liquid to be frozen is not required.
- the circulation device and optionally a metering device for a cleaning agent can therefore consist of inexpensive components.

- the pipeline through which the cleaning liquid is conveyed by the circulation pump back into the tub opens from above into the tub.
- the pipeline opens below a predetermined for the filling of the tub levels. This avoids that during the circulation of the cleaning liquid caused by the circulation pump to an undesirably high foaming in the tub.
- the circulation device has a submersible pump arranged in the tub. This promotes the cleaning fluid directly from the tub back into the tub, without having to rely on an additional pipe outside the tub. If the submersible pump is not firmly connected to the tub, it can be removed from the tub during the production of flake ice.
