Ejector device for vacuum drying
First Claim
1. An ejector device for vacuum drying, comprising:
- a first chamber with a first passage extending in a first direction, and a second chamber with a second passage extending in a second direction, wherein said first and second passages are adapted to communicate with each other;
an adjustable nozzle adapted to communicate with said first and second passages, and to control flow from said second passage to said first passage, and to eject high-speed air toward said first chamber through said first chamber in said first direction, wherein negative pressure can be formed in said first passage, and wherein stagnant air and steam existing in said second chamber can be drawn from said second chamber and into said first chamber, via said first and second passages, wherein the inside of said second chamber can be vacuum-dried thereby.

Abstract
The present invention relates to an ejector device for vacuum drying having at least first and second passages for connecting a first chamber with a second chamber, wherein the chambers are arranged substantially at right angles with respect to each other, and the ejector is adapted to vacuum dry the inside of the second chamber by means of high speed air flow toward the first chamber. The flow toward the first chamber preferably travels through the second passage from the first passage, on the side opposite the first chamber, to induce a negative pressure in the first passage. This way, the change in kinetic energy draws the stagnant air and steam existing in the second chamber into the inside of the first chamber.

10. An ejector device for vacuum drying, comprising:
-
an ejector with at least first and second passages for connecting first and second chambers in mutual communication, wherein the ejector is adapted for vacuum-drying the inside of the second chamber by ejecting high-speed air toward the first chamber from the first passage'"'"'s side opposite the first chamber to induce a negative pressure in the first passage due to a change in kinetic energy so as to draw via the second chamber stagnant air and steam existing in the second chamber into the inside of the first chamber; and
wherein an air ejector nozzle is adjustably connected to said ejector at the first passage'"'"'s end opposite the first chamber, and provided with a third passage for connection with an air pump, and an air hole or channel to be in communication with the first and second passages, said air jet nozzle forming a gap between the nozzle'"'"'s front outer surface and a wall of the first passage beyond the position of the second passage. - View Dependent Claims (11, 12)
