A. The ring die pellet mills were designed at around the 1930's based on the design of ring die. The basic pelleting principle of the ring die pellet mill is a simple operation where feed mass is distributed over the inner surface of a rotating, perforated die ahead of each roll, which compress the feed mass and compress it into the die holes to form pellets.

Results obtained using oven methods should not be termed "moisture." They should be termed "loss on drying," and the drying conditions should be part of the term, for example, "loss on drying, 104°C/2 h, 5.0%." Drying at 135°C should be eliminated or restricted to very few materials for which it has been validated.

The main limitation of tensiometers is that they do not measure soil matric potential values as low as the usual wilting values. The actual range of effective measurement is only from 0 to -0.85 bars. Tensiometer is useful for measuring moisture in sandy soils than that of clay soils, because of higher matric potentials in the former soils. 4.

DETERMINATION OF MOISTURE AND TOTAL SOLIDS

High moisture samples. Food samples that have high moisture contents are usually dried in two stages to prevent "spattering" of the sample, and accumulation of moisture in the oven. Spattering is the process whereby some of the water jumps out of the food sample during drying, carrying other food constituents with it.
