Definitions
- the invention relates to a flake ice machine according to the preamble of claim 1 and a method for monitoring a flake ice machine according to the preamble of claim 5.
- Such flake ice machines produce relatively thin flake ice for keeping food fresh, especially in the butcher industry.
- the cooled evaporator roller is immersed in the water of the evaporator pan. When the evaporator roller rotates, the amount of water entrained by the jacket surface freezes. The resulting ice layer is detached from the outer surface of the evaporator roller before being immersed again in the water by a device provided on the roller, for example a scraper. This is done either by scraping or chipping.
- the evaporator roller contains a refrigeration evaporator, which is connected to a refrigeration machine located outside the roller.
- a control device is provided for monitoring and controlling the evaporator roller, the refrigerator and the water supply valve.
- the control device determines the filling time, the ice production and the water level in the evaporator pan supervised. If the specified limit values are exceeded or undershot, the water supply valve, the drive of the evaporator roller or the chiller are switched off and the user receives an error message.
- the flake ice machine according to the invention with the characterizing features of claim 1 and the method according to the invention with the characterizing features of claim 5 have the advantage that the time in which the water supply valve is open is limited with the help of a clock.
- the clock starts when the water inlet valve opens.
- the water inlet valve is closed when either the maximum Water level is detected by the sensor or a predetermined filling time has expired.
- the filling time is specified in such a way that, in the case of a flake ice machine working faultlessly, filling up to the maximum water level is possible on the one hand and on the other hand an overflow of the evaporator pan cannot occur within the filling time. If the end of the filling time leads to the water supply valve being switched off, the user receives an error message. In this case, either the sensor for determining the maximum water level or the water supply valve are defective, or the water supply is not guaranteed for other reasons.
- the minimum of the water level can also be monitored according to an advantageous embodiment of the invention.
- the clock is started when the water supply valve closes. If the flake ice machine works properly, the water level drops when the water inlet valve is closed due to the ice production and the removal of the flake ice pieces. When a minimum water level is reached, the water inlet valve opens again. A minimum sensor is provided to detect the minimum water level. If the minimum water level is not detected due to a defect in the minimum sensor or a lack of ice production, an error message is sent to the user after a specified drain time. This can check the functioning of the flake ice machine and switch it off if necessary.
- the flake ice machine can be monitored not only in the operating state but also when the flake ice machine is started up after a standstill. To do this, the sensor first determines whether the maximum fill level in the evaporator pan is present. If this is the case, the residual water valve opens until the sensor no longer detects a maximum fill level. The residual water valve is necessary to remove the residual water or contaminated water in the tub after the flake ice machine has been idle for a long time, so that it is no longer used for ice production. A clock starts when the residual water valve is opened. After a specified time, it is checked whether the maximum fill level is still present. If this is the case, an error message is sent to the user.
- Causes of the error message can be a defect in the sensor or a defect in the Residual water valve.
- the proper functioning of the residual water valve is necessary to meet the high demands placed on the hygiene of the flake ice machine due to the use of flake ice in the food sector.
- the drainage of residual water or contaminated water must be ensured.
- the defect of the residual water valve is not noticed since only the operating state is monitored. However, the operating state is not affected by a defect in the residual water valve, since the residual water valve is not used during operation.
- the water inlet valve is opened and a clock is started. If a predetermined time is exceeded without reaching the maximum fill level, the user receives an error message. Possible causes can be a defect in the sensor or the water supply valve or the lack of water supply due to other causes.
- the monitoring periods when the flake ice machine is started up after a standstill are usually different from those monitoring periods in the operating state.
- This procedure also checks when the flake ice machine is put into operation after a standstill to determine whether there is water in the evaporator pan.
- a sensor is used for this purpose, which determines the electrical conductivity of the contents of the evaporator pan.
- two electrodes on the bottom of the evaporator pan, which are insulated against the evaporator pan, are suitable. It takes advantage of the fact that water conducts electricity, while air acts as an insulator.
- the method according to the invention and the device according to the invention can detect the presence of water in the evaporator trough without checking the conductivity. This eliminates the problems with water types with low conductivity, for example distilled water, and the disadvantages of electrolysis of the water by the two electrodes.
- the method according to the invention and the device according to the invention can also be combined with known methods and devices in which one temporal monitoring of the water level takes place.
- a defect in the water supply, the water supply valve or the sensor for determining the maximum or minimum fill level can be identified using the method according to the invention. If, on the other hand, there is no change in the water level over time, there is a defect in the roller or the cooling. This makes it possible to select the sources of error. If, in addition, the method described above for checking the flake ice machine before commissioning is used, then a complete inspection of the flake ice machine is guaranteed.
- Float switches for example, are suitable as sensors for determining the maximum or minimum fill level in the evaporator trough. These have the advantage that they are independent of the chemical and physical properties of the liquid to be frozen. In addition, a float switch can detect both the maximum and the minimum water level. Therefore, only one float switch is required in the evaporator pan.
- the water supply valve When the minimum is reached, the water supply valve is opened with a time delay of, for example, 15 seconds. This causes the water level to drop below the specified minimum before water flows in again. This prevents the contact actuated by the sensor from being triggered several times during movements on the water surface, for example when waves are formed. This would lead to rapid wear of the contact. Likewise, the water supply valve can be closed with a time delay when the maximum is reached.
- the control device is equipped with a logic circuit which, depending on the event, causes the water supply valve or the residual water valve to open or close and, if necessary, to send an error message to the user.
- FIG. 1 flake ice machine in side view
- An evaporator roller 1 is rotatably mounted in an evaporator pan 2 of a flake ice machine and is driven in rotation by an electric motor or a geared motor (not shown).
- the lower part of the evaporator roller 1 is immersed in the water 3, which is filled into the evaporator pan 2 through a water inlet valve (not shown in the drawing).
- the outer surface 4 of the evaporator roller 1 is wetted with water when rotating. The water freezes on the surface cooled by the chiller. This forms a thin layer of ice, which is separated from the outer surface with the aid of a fixed ice scraper 5 and fed to a collecting container (not shown).
- a float switch 6 is arranged on the side of the evaporator pan and is immersed in the water 3.
- FIG. 2 shows the individual events which are checked when the flake ice machine is put into operation after a standstill. If the start-up test runs without error messages, the function of the sensor, the water supply, the water supply valve and the residual water valve is guaranteed.
- the start-up test shown in FIG. 2 can be repeated at predetermined time intervals of, for example, 15 minutes, so that ice production can be continued automatically when water returns.
