Aug 01, 1998 A constant mass of the test portion is obtained after 4–5 h at a drying temperature of 87C and by flushing dry air (0.01 mg H 2 O L-1) through the test portion. Under these conditions a moisture content is obtained that corresponds well with the moisture content determined by the EU method.

Drying foods in a vacuum oven therefore has a number of advantages over conventional oven drying techniques. If the sample is heated at the same temperature, drying can be carried out much quicker. Alternatively, lower temperatures can be used to remove the moisture ( e.g. 70 o C instead of 100 o C), and so problems associated with degradation ...

Equilibrium Moisture Content Formula: Oven-dry method is not the only way of measuring MC. We can estimate MC of specimen using relative humidity and temperature of the environment. If given enough time, wood specimens will eventually reach a moisture equilibrium with the environment depending on the temperature and relative humidity.

Determination Of Water Content Of Soil By Oven Drying Method

Determination Of Water Content Of Soil By Oven Drying Method

The calculations of water content are done from the following equation-. The formula of calculation of water content through the oven-drying is w= (M2-M3 / M3-M1).100. Here w is water content, M 2 is the mass of the container with moist soil, M 1 is the mass of the empty container, M 3 is the mass of the container with dry soil.
