Crystallized beads of a product which can be supercooled and process to prepare them |
摘要 |
Prepn. of crystallised pearls of a prod. showing surfusion comprises: (1) melting the prod. if necessary; (2) fragmenting the melted mass into droplets; (3) cooling the droplets to a temp. below the glass transition temp. of the prod. so the droplets harden by vitrification; (4) keeping the vitrified pearls at a temp. below the Tg and contacting them with crystallisation seeds; (5) crystallising the pearls by raising the temp. to above Tg; and (6) recovering the crystallised pearls. Also claimed are the crystallised pearls produced as above; crystallised pearls of a prod. showing surfusion which has a glass transition and not contg. crystallisation additives; crystallised pearls comprising a least one glyceryl gaiacolate, and an appts. comprising a 1st chamber for forming the pearls, a 2nd chamber for recovering the vitrified pearls and a 3rd chamber for crystallising the vitrified pearls. |
