Two, adopt porous reducing pattern to produce particulate dry ice, solved and arranged a plurality of cylinder bores on the cuboid pattern and can produce the problem of more snow shape dry ice stagnant area.The existence of these stagnant areas can make snow shape dry ice can't be forced out pattern, thereby forms the dry ice lumps of monoblock, makes the piston cisco unity malfunction.Change the single aperture of cylinder nib the form of reducing into, the dry ice stagnant area is thoroughly decomposed, thereby make snowy shape dry ice in the curing room can both be squeezed into each nib and be shaped.
Three, take reducing to be divided into the form in a plurality of holes to the charging of liquid CO 2, it is changed mutually meet theoretic perfect condition, simultaneously, arrange blast pipe to such an extent that form heat exchange structure with feed tube, the low-temperature carbon dioxide gas that curing room is discharged carries out heat exchange by heat exchanger and the liquid CO 2 that enters curing room, utilize this two measures, can improve liquid-solid conversion ratio.
Four, by electric heater unit being set in the curing room exhaust ports, eliminated the ice storage phenomenon that produces in exhaust ports, can prevent also that simultaneously the snow shape at curing room back cavity place from piling up obstruction, device can normally and reliably be moved.
Five, switch board is set, former single programme-control is designed to can finish the adjusting control of two (block and granular dry ice production) or a plurality of distinct programs in a switch board, respectively each production routine is imported variable range controller, switch by change-over switch then, realize the automation execution of each required function, significantly reduced manual operation, the automaticity height.
