HOME EQUIPMENT FOR DEHYDRATION 



For home dehydration units there are definite limitations to construction. The 

 deh} drator must be simple enough in design so that an average person can build 

 it with ordinary home tools. Critical materials should be avoided as much as 

 possible in construction. However, it should afford maximum control of the 

 factors involved in dehydration, and produce results as quickly and efficiently 

 as possible. 



While several units have been built and tested in the laboratory, the following 

 two designs are recommended for both simplicity in construction and efficiency 

 of operation. They are similar in size and structure, the size having been de-
