Title
Transfer of moisture from damp to dry wheat in storage
Description
This Technical Memorandum of the British Society for Research in Agricultural Engineering describes a laboratory experiment to determine the rate of moisture transfer from wheats of various moisture contents, to dry wheat when mixed in with them, in an effort to reduce artificial drying time of damp wheat when harvested. Information is presented under these headings:- I. Introduction;
2. Scope of Experiments;
3. Preparation of Samples;
4. Method;
5. Results;
Conclusions; Table I: Change in weight and moisture content; Table II: [untitled]; Table III: Relative humidity of grain atmosphere in dry and mixed grain: Figure I: First experiment time-moisture content; Fig. 2: Comparison of three treatments, time-moisture content difference
