Determination of Moisture Content by Oven Drying Method

Jul 06, 2020 The Oven dry method is widely used for the determination of water content. The loss of weight that happens due to drying results in the measurement of the moisture content of the sample. The temperature at which the sample is oven-dried ranges from 110 o C +- 5 o C. The oven-dried mass is usually recorded after 12 to 24 hours.

How Drying Preserves Food - University of Georgia

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 ...
