- the support 7 is, if necessary, raised to bring the top of the collecting container 33 closer to the ceiling of the enclosure 6 so that the edge of the opening of the collecting container 33 surrounds the access opening 8 made in the upper part 61 of the enclosure 6 of the metering station 5.
- This collecting container 33 is detected by the presence detection sensor 13.
- the enclosure 6 of the dosing station is raised to allow the device 11 for controlling the opening / closing of a container 30 to surround the valve 31 for emptying the container, this valve 31 being partially housed in the opening 8 d access to the enclosure 6. Compression is applied via the pressurized air supply device 12. on the flexible bag constituting the container 33 to allow its emptying in the open state of the emptying valve of the container controlled in opening by the device 1 1 for controlling the opening / closing.
- the valve is open for a period of time controlled from the data resulting from the weighing operated continuously by the weighing system 18 until the exact mass required is obtained.
- the valve can then be closed.
- the pressure is maintained on the flexible pouch of the container 30 at least throughout the emptying phase.
- the enclosure 6 can be lowered.
- a new emptying can be carried out after selecting a new container by repeating the operations described above.
- the device 16A or 16B for forced air circulation can be activated and the member 19 for shutting off the circuit 15 for the circulation of gaseous fluid in communication of the enclosure 6 with the outside of the chamber.
- enclosure 6, when present, can be opened to allow evacuation of at least part of the contents of enclosure 6, that is to say of the volume of enclosure 6 containing volatile organic compounds , outside enclosure 6 to avoid any risk of explosion.
- the control of the member 19 for shutting off the circuit 15 for circulating gaseous fluid of the enclosure 6 with the outside of the enclosure 6 and / or of the device 16A or 16B for forced air circulation can be perfect using the sensor 20 for detecting volatile organic compounds when such a sensor is provided or using the weighing system 18.
- the member 19 for shutting off the circuit 15 for the circulation of gaseous fluid in communication between the enclosure 6 and the exterior of the enclosure 6 can thus be closed before the end of the weighing, when there are still a few grams left. weigh, to avoid air flows which could disturb or impair the accuracy of the dosage.
