Title:
SPHERICAL LUMP DRY ICE PRODUCING MACHINE
Document Type and Number:
Japanese Patent JPH04209714
Kind Code:
A
Abstract:

PURPOSE: To improve molding efficiency by pressing and collecting dry ice formed in a vaporization cylinder by a press piston, feeding into a press cylinder under pressure and producing spherical lump dry ice having a given size.

CONSTITUTION: Liquid carbonic acid is fed from a gas introduction part 4 to a vaporization cylinder 3 and liquid carbonic acid is vaporized in the vaporization cylinder 3. Consequently, the interior in the vaporization cylinder 3 is quenched and dry ice is precipitated in the vaporization cylinder 3. Then, dry ice is pushed in a dented part 10 with spherical surface of a press cylinder 1 by a press piston 5 and compression-molded into a spherical lump dry ice (a) having a given size. Successively the press cylinder 1 is separated from a molding receiver stand 2 to recover the spherical lump dry ice (a).
