HIS is the only system for uniformly drying, on a large 
scale, any produce or material by graduated and easily 
controlled heat. It requires no power. The treatment as to 
temperature is easily regulated, so that having determined the 
most advantageous process for the material in hand, it can be 
arranged that every part of every charge shall be so treated 
as to secure the maximum of output and quality. 
The drying is progressive, not sudden in its application, 
the material passing automatically from the minimum to the 
maximum temperature. The air is pure, not burned. 
Turns out from 2 to 20 tons per day of perfect quality. 
Erected complete in any part of the world for an inclusive 
price according to size.
