Prefamac 30 / 80 Moulding Machine

Frequently Asked Questions

 

 

 

  1. FIRSTLY check the mechanical thermostat. The mechanical security thermostat is placed at the bottom on the back of the machine.

  2. Set this thermostat once and for all at +/- 50°C.

  3. This thermostat gives an extra security on your machine for the case of eventual electricity problems.

  4. It's will indicate the maximum acceptable temperature for your chocolate, and thus different for each type of chocolate you are working with.

  5. Please check this thermostat each time that you are replacing your machine.

  6. When you install it ex:. only on 20°C it is not possible to reach chocolate at 30°C. - Is your Omron E5CJ still working ?

  7. Is it giving an error function ? Can you replace it with the thermostat of another machine ?

  8. Is your sensor still fixed ?

  1. Only the function "up" and "down" will work.

  2. All programming functions are done and blocked by Prefamac.

  1. Push the right hand and the left hand side of the thermostat.

  2. Take the thermostat out of the machine.

  3. Replace it with a new thermostat.

     

4. How to restart my machine, after having pushed in the emergency valve ?

By turning the red emergency stop valve a little, and then pushing the green start knob. The machine will then start.

5. Which machine functions will be blocked after pushing in the emergency valve ?

In case of problems, you must push the emergency stop valve with your left knee. Hereby +/- the complete activity of the machine will stop, ex: the wheel, the vibration table, the different plugs (for your heating lamps, your enrober belt with/without detailer-blower-...). 

Only the thermostat (heating) will still work, to keep your temperature at the same level. By turning a little bit on the emergency stop valve, and then pushing the green start knob, the machine will restart.

 

  1. Turn the direction switch to the right to start moulding.

  2. Turn this switch to the left to start enrobing.

  1. The 4 spirals on which the vibration table must be installed, must be placed on the 4 projections of the moulding machine, located near the tank.

  2. The (male) plug of the vibration table must therefore be placed in the (female) plug contact of the vibration motor on the inner side of the machine, located near the tank.

  1. We have added a slip coupling on the reductor of the motor, which is blocking the wheel and the stirring arm in case of chocolate in fixed form.

  2. Wait until all chocolate is liquid.

  3. Let the machine rotate again.

  1. The chocolate can be drained out of the machine, via the tap on the underside of the machine.

  2. The tap must be warmed up a little bit first, to avoid stoppages.

  1. Do not leave the machine on without processing chocolate. This may result in unintentional temperature fluctuations.

  2. Never let the volume of chocolate reduce by less than half in the tank, as this may also cause processing problems.
