Method and device for refilling an evaporator chamber

A device for continuously refilling an evaporator chamber, the device comprising:

• a vacuum lock for solid material;
• a vacuum chamber attached to the vacuum lock, wherein the vacuum chamber is provided with a partition disposed therein, which is permeable to liquid and impermeable to solid material and extends upward from a bottom of the vacuum chamber, into filling region coupled to the vacuum lock and a second region;
• a connecting channel coupled into an evaporator chamber attached to the vacuum chamber at the second region, wherein the evaporator chamber is continuously refilled from the vacuum chamber through the connecting channel;
• a heating jacket of the vacuum chamber and of the connecting channel, and
• a switchable cooling device on the connecting channel,
• wherein the partition separates the filing region of the vacuum chamber from the second region thereof, wherein a perforation is disposed within the partition at a perforation level proximate to the vacuum chamber bottom and wherein the connecting channel extends to a channel level within the second region of the vacuum chamber above the perforation level.
