The role of α-lactose monohydrate as a grinding material ...

In addition to grinding, it is essential to give a certain time for mixing the materials with α-lactose monohydrate during trituration. The purpose of a mixing operation is that the whole process leads to an internal structure of desired quality. Mixing processes for α-lactose monohydrate and granular materials often ask to make a product with a degree of homogeneity suitable for the final ...

Influence of ageing, grinding and preheating on the ...

01/09/2008  Upon heating from room temperature up to 180 °C, the proportion of β-lactose is higher for native material than for ground samples, which can be explained by the decrease of the dehydration temperature caused by grinding since this decrease induces a shorter residence time of H 2 O molecules in the crystal lattice upon heating.

01/09/2008  The fusion–recrystallization process occurring between anhydrous forms of α-lactose at ca. 170 °C is not significantly affected by grinding, whereas a preheating treatment induces an unexpected large increase of the enthalpy associated with this transition. Our observations and interpretations confirm the important role of water molecules in the crystal cohesion of the title compound and illustrate the

Lactose Food Industries Hosokawa Micron Powder

Lactose is a simple sugar in milk and is a major component of whey. Lactose is purified from the whey produced as a byproduct of the cheese and casein industries. Several million tons of lactose is produced annually. Lactose is purified to make food and pharmaceutical grade lactose in a process shown here involving evaporation, crystallizing, centrifuging, filtering, drying, and milling.

The non-crystalline solids of a- or a-lactose were then transformed into their counterparts by the mechanochemical effects of grinding. Lactose has been widely used as a diluent in tablets because of the favourable characteristics of the bulk powder. Commercial grades may vary in their content of crystalline (amonohydrate, a-anhydrate, p-anhydrate) and amorphous forms (Norris Greenstreet 1958; Goulden 1958; Itoh et al 1977, 1978) and many grades of lactose

Some manufacturers will need to compact lactose to reduce fines or improve flow properties. The roller compaction and dry granulation process takes fine powder and turns it into a useable substance. Roller compactors densify the lactose powder, turning it into a more condensed material. A feed screw is used to feed material to the compaction rollers, slowly allowing the rollers to compact the coarse and fine

Results were compared with data obtained using industrial spray-dried lactose and lactose samples with different degrees of crystallinity. XRPD analysis revealed that roller compaction reduced the crystallinity of α-lactose monohydrate, and the resulting material is similar to spray-dried lactose in behavior as a direct compression excipient. Roller compaction introduced desirable ...

The crystalline lactose samples were transformed into non‐crystalline solids by mechanical stress during grinding. After grinding, the water content of all ground lactose samples increased, and the samples had about 2 mol water per lactose after 10 h grinding. After 10 h grinding of α‐monohydrate and α‐anhydrate, 10 and 15%, respectively, of α‐lactose was transformed into β‐lactose by the mechanical treatment.
