摘要

A method and apparatus to automatically produce blocks of solid CO2 at low pressure. The apparatus includes at least one closed mold coupled to a liquid CO2 conditioner and a CO2 gas recovery system, and a control panel for automatic operation. The method consists in supplying liquid CO2 to this mold at a low pressure in order to fill the mold with CO2 snow of low density during a definite period of time, to then raise the pressure inside the mold to an intermediate pressure by supplying liquid CO2 at this pressure (and at a temperature of approximately -40 DEG C.) to form a dense mass of solid CO2 which after a definite time will block the admission of CO2 to the mold, causing a significant pressure drop that is used to create a signal to automatically close off the supply of liquid CO2 and finalize the production cycle of the block.
