Abstract
The invention concerns a method for drying at least one cell of the electrostatic precipitator of a smoke treating unit in a system of a coffee beans roasting apparatus and a smoke treating unit, said method comprising the step of passing hot air through said cell, while said cell is positioned inside the electrostatic precipitator and while said cell is switched off.
Claims8
A method to dry at least one wet removable cell of an electrostatic precipitation smoke filter of a smoke treating unit of a roasting system, the system comprising:
- a roasting apparatus,
- a smoke treating unit configured to treat the smoke produced by the roasting apparatus, the smoke treating unit comprising the electrostatic precipitation smoke filter,
- the electrostatic precipitation smoke filter comprising the at least one wet removable cell,
- the at least one wet removable cell comprising ionization wires, collecting electrodes and repelling electrodes,
- the wires and electrodes being supplied with an electrical power,
- wherein the method comprises at least the step of passing hot air through the at least wet removable cell, while the at least one wet removable cell is positioned inside the electrostatic precipitator and while the at least one wet removable cell is switched off, and
- wherein the hot air is generated by the roasting apparatus while the roasting chamber of the apparatus is empty, in particular void of coffee beans.
A computer program comprising instructions which, when executed by a computer, processor or control unit, cause the computer, processor or control unit to perform the method to dry at least one wet removable cell of an electrostatic precipitation smoke filter of a smoke treating unit of a roasting system, the system comprising:
- a roasting apparatus,
- a smoke treating unit configured to treat the smoke produced by the roasting apparatus, the smoke treating unit comprising the electrostatic precipitation smoke filter,
- the electrostatic precipitation smoke filter comprising the at least one wet removable cell,
- the at least one removable cell comprising ionization wires, collecting electrodes and repelling electrodes,
- the wires and electrodes being supplied with an electrical power,
- wherein the method comprises at least the step of passing hot air through the at least one wet removable cell, while the at least one wet removable cell is positioned inside the electrostatic precipitator and while the at least one wet removable cell is switched off, and wherein the hot air is generated by the roasting apparatus while the roasting chamber of the roasting apparatus is empty, in particular void of coffee beans.
