Solar Crop Drying
Demonstrations

Conserval Engineering Inc.

This project demonstrated the use of solar energy, displacing fossil fuels, to dry
crops grown in California using the low cost unglazed transpired solar collector. The transpired collector or SOLARWALL
system has been installed in over twenty countries primarily for heating commercial and industrial buildings. This
project for the California Air Resources Board, under its Innovative Clean Air Technologies grant program, was
the first application of the transpired collector technology in the USA for drying of crops and it appears to have
been the first significant improvement in solar drying technology since the 1980's.
The presentation will explain the technology, a summary of the five solar drying demonstration installations completed
in California, which includes drying of walnuts, pecans, prunes and herbs, monitoring results and the benefits
of using solar drying. As the California projects represented the USA contribution to the International Energy
Agency Task 29 solar drying project, where the same collector technology has been used, a brief summary of other
international drying projects will also be presented. |

| John Hollick is president
of Conserval Engineering Inc. of Toronto and Conserval Systems Inc. of Buffalo, NY, suppliers of the SOLARWALL
solar air heating system. He is a professional engineer registered in Ontario Canada and Delaware, U.S.A. He became
actively involved in designing solar air heating systems and formed Conserval in 1977 to market turnkey solar and
energy saving projects. In the early 1980's, Mr. Hollick developed the concept of preheating outdoor air in industrial
applications by using wall mounted solar collectors. In the 1990's, he patented and introduced the all metal building
integrated solar wall heating system, called a transpired solar collector by Dept of Energy. Mr. Hollick has been
granted several world wide patents on the various SOLARWALL designs and has received numerous awards for his inventions
and projects. Hundreds of SOLARWALL installations are now installed in over twenty countries for ventilation air,
space heating and crop drying applications. |
