  • Cleaning method using both wet and dry steam, and apparatus adapted therefor
    Patent number: 5275849
    Abstract: The apparatus, system and method utilize sequential sprays of wet, low-temperature steam, and dry, high-temperature steam to clean the exterior of laminated objects as well as to effect volatilization of liquid contaminates trapped between lamina thereof. Water is injected into the conduit through which the low-temperature steam is delivered, so as to produce a desirable concentration of droplets therein. A conveyor moves the laminated objects along a horizontal path through zones in which they are sprayed by the low temperature and high temperature steam, and then through a zone in which they are electrostatically coated with powder.
    Type: Grant
    Filed: April 21, 1992
    Date of Patent: January 4, 1994
    Assignee: Electrostatic Technology, Inc.
