Structure and function

Function

The BioMaster® serves as the infeed station in the system. The system offers an economically and ecologically sensible, hygienic solution for recycling kitchen waste and food waste. The system is used in commercial kitchens, canteens, hotels, food service and communal catering. The BioMaster® converts the waste produced into a homogenous biomass.

Kitchen waste and food waste are fed into the loading chute of the BioMaster® and homogenised in the BioMaster® using the water contained in the waste and adding process water.

Additional water can be fed in via a cleaning nozzle to cleaning the loading chute and to process extremely dry or very light waste.

The resulting biomass is pumped out of the BioMaster® and transported via a closed pipe system to the storage tank.
When using the BioMaster® as an infeed station of a vacuum plant, the biomass is conveyed through the pipe system by means of vacuum.

13. Check the vacuum ventilation gap at the rear of the lid seal. The gap must be at least 2 cm wide. If necessary, move the seal by hand on both sides until there is a 2 cm gap.

14. Close the lid.

WARNING
There is a danger of crushing when closing the lid!

Measures in case of longer installation standstill

NOTE
Before the installation is shut down for more than two days, the following additional measures must be taken:

1. To minimise the risk of pipe blockage, clean the transport pipe by washing it with maximum 40°C hot water:
2. Pour the hot water carefully into the loading chute up to the ‘Max.’ marking.
3. Press the white PUMP button. Keep it pressed until the loading chute is completely empty.
4. Repeat this procedure several times, if necessary, depending on the length of the transport pipe to the storage tank, until the pipe has been completely flushed.

Switching off **

**

NOTE
Switch off the BioMaster® for shorter downtimes, too, e.g. when changing shifts, overnight or on weekends.

5. Depending on the duration of the downtime, clean the BioMaster®.
   6. Switch of the BioMaster® at the main switch – position OFF.
   7. The STANDBY indicator goes out.
   8. Close the water supply stop valve.

Fault finding
WARNING
If irregularities in the work sequence, unusual noises or malfunctions occur, immediately trigger an emergency stop and inform the responsible specialist personnel.
No unauthorised manipulation by the operating personnel!

Any troubleshooting which goes beyond the simple inspection of the in-put loading chute and the grinder may only be carried out by qualified and authorized personnel.

• Is the machine connected to the power supply?
• Is the main switch switched on?
• Is the EMERGENCY STOP button unlocked?
• Are the necessary fuses operational?

• Is the storage tank full and is the ‘Fill level indicator 100 %’ lit up red? Have the storage tank(s) emptied immediately.
• Is the EMERGENCY stop button unlocked?
• Is the red ERROR fault indication light lit up? (See next item).
• Is the lid properly closed? The STANDBY indicator light must be lit up.

The ERROR fault indication light is continuously lit up|

• Overheating of the pump, mill motor or control unit.
  • Check the mill and pump.
  • Check the motor temperature.
• If there is no fixed connection: The BioMaster®’s electrical plug is not correctly inserted in the socket.
  • Check the machine plug.
  • Check whether the plug screw connection is tightened.
• Grinder jammed or motor overloaded.
  • Check loading cute contents for foreign matter.
  • Check that the grinder can be rotated using an unlock- ing key.
  • Remove foreign matter.
• Open the service hatch and set the overload circuit breaker to ON.

Biomass is not pumped out of the loading chute|

• BioPump® is blocked.
• With the lid open, press the PUMP button for about five seconds and observe the fill level in the loading chute. If the fill level sinks, repeat the procedure until the loading chute is emptied and the BioPump® is free again.
• If the fill level remains the same, the grinder, BioPump® or transport pipe is blocked. If this is the case, call a technician for help.
• Check whether a foreign object (plastic, bandage, cloth, etc.) is blocking the grinder.
• The biomass in the machine is too dry and therefore cannot be pumped away. Try filling it with hot water.
• Any replacement of the pump impeller should only be carried out by trained personnel.

The loading chute is emitting an unusual noise|

• Stop the BioMaster® with the EMERGENCY STOP button, check loading chute contents for foreign objects (cutlery, etc.)
• Remove foreign matter.

The grinder no longer rotates.

WARNING

|

• Switch off the main switch – OFF position. Completely clear the loading chute.
• Switch on the main switch – ON position.
• Pump out the remaining liquid by pressing the PUMP button.
• Switch off the main switch – OFF position.
• If necessary, remove jammed solid parts/foreign materials with the aid of a suitable tool.

• Turn the jammed grinder forcefully to the left and right with the unlocking key until the grinder is able to move again.
• Then rinse the BioMaster® with hot water and pump the water out again by pressing the PUMP button.
