ABSTRACT:
A cleaning device using fine frozen particles electrically charges the fine frozen particles produced by atomizing a liquid within a refrigerated atmosphere, controlling the speed, direction and divergence of the charged particles to cause them to strike a desired portion of an object to be cleaned. All of these operations are performed in a variable degree of vacuum. Thus, the speed, direction and divergence of the particles and the particle grain size can be precisely controlled.
