by Eric Meier Allowing lumber to passively sit at a given humidity level in order to obtain a desired EMC (air-drying) may be the simplest and least expensive method of seasoning wood, but it is also the very slowest. Drying times can vary significantly depending upon wood species, initial moisture level, lumber thickness, density, ambient ...

expressed as the percentage, by oven-dry weight, of pulp obtained from the original wood weight. A recovery value of 45% means that for every 100 oven-dry pounds of wood processed, 45 oven-dry pounds of pulp is produced. When expressed in this manner, pulp yield is mainly a function of the pulp-ing process. There is some difference between hard-

Microwave Drying. Microwave drying (Figure 10) is extensively used to dry food materials due to the high drying rate and uniform drying ( Nair et al., 2011 ). Microwave drying can also improve the quality of some food materials. Microwave drying can enhance the drying rate during falling rate period (final stage of drying).

Oven drying is slower than dehydrators because it does not have a built-in fan for the air movement. (However, some convection ovens do have a fan). It takes about two times longer to dry food in an oven than it does in a dehydrator. Thus, the oven is not as efficient as a dehydrator and uses more energy. Homemade Solar Dryer plastic sheeting ...

Place the 1-inch sections (sawn earlier from the sample boards) in an oven at 215 degrees F (102 degrees C). After the pieces are dry (usually 18 to 24 hours depending on the oven), reweigh them and obtain the oven-dry (O.D.) weight. Calculate the moisture content (MC) of the sections with the formula below.

The % oven-dry solids or %OD is calculated by: %OD = dry weight/wet weight *100. Moisture content can be calculated two ways: % Moisture content dry basis = (wet weight – dry weight)/dry weight *100. This expression is the most commonly used expression of moisture content in wood. It is easily converted to %OD by subtracting the %MC dry basis ...
