Patent number: 6470593Abstract: 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.Type: GrantFiled: November 1, 2001Date of Patent: October 29, 2002Assignee: Delta Medical Co., Ltd.Inventor: Kyu Young Seo
