摘要:
The invention relates to a press device for manufacturing tablets from a mixture of at least one component, comprising: first means (7) for controlling a first punch, the first control means (7) comprising a compaction cam (9) for displacing the first punch (3) into a compaction position, said compaction cam (9) comprising a cam path on which said first punch (3) is capable of being displaced, the cam path comprising a planar portion (90) substantially perpendicular to the axis of the first punch (3), the planar portion (90) extending over an angular section comprised between 5° and 170° for maintaining the first punch (3) in a compaction die (2) at a fixed axial compaction position during a determined compaction maintaining time, second means (7) for controlling a second punch, the second control means (8) also comprising means for maintaining the second punch in said die at a fixed axial compaction position at least during said compaction maintaining time, so as to maintain, during said compaction-maintaining time, the confinement volume (V) at a constant volume corresponding to the compaction volume for forming the tablet.

The invention relates to use of superabsorbent (co)polymers (SAP) as an agent for preservation treatment of animal hides. The SAP is used preferably in conjunction with salt or other hygroscopic agent, in particular 50% NaCl/50% SAP by weight. Suitably treated hides are obtained in 24 hours and one-half less salt is used in comparison to the prior art, disadvantages such as surface brine, salt in slaughterhouse waste, and others being eliminated.
