Abstract
A block former comprises a portable device for compression forming of carbon dioxide particles into a non-homogenous block of carbon dioxide. The formed non-homogenous block can be used with carbon dioxide blasters that shave the formed block, and then eject the carbon dioxide shavings into a pneumatic jet as a blast media for cleaning surfaces. The block former further comprises a control system comprising a logic system of switches, valves, and timers to perform a timed sequence of events to form loose carbon dioxide particles into a non-homogenous block, to release compression on the block, and to eject the formed block from the block former. A single compression surface is provided to compress the carbon dioxide particles block, to release pressure on the block, and to eject the block from the block former device. The carbon dioxide particles used to form the non-homogeneous block can vary in size from snow to chunks or pellets.
