Solar Cookers/driers and simple temperature control for raw food

[Guest guest]

Hi Ron,

This is a very interesting suggestion. I hadn't thought of concentrating the

sun's energy for drying food in the context of my raw food diet.

 

As soon as I saw this, I remembered another piece of simple technology that

would be very useful in ensuring that while the food dried quicker, it would

still be raw.

 

It is a temperature activated device for opening a ventilation window in a

greenhouse to keep the greenhouse from overheating. The device doesn't use any

electricity, is self-contained, and is mechanically activated when it reaches

the temperature it is set for.

 

Since the range of temperatures which are too hot for plants is similar to the

maximum drying temperatures for raw food, these devices could be adapted for

controlling the maximum temperature for enclosed raw food driers.

 

This would be very useful for the solar cookers which are enclosed boxes for

opening one pane of the glazing on the top to prevent the cooker from

overheating and cooking the food as it dries.

 

When one pane is opened even a little bit due to excess heat, this would help

create a draft in the food drier, and this air movement would help accelerate

food drying.

 

An additional advantage of this approach is that it would help protect the food

from rain showers and damp nights because the ventilation window would

automatically close as soon as it cooled off due to reduced sunlight.

 

May your day be filled with clarity, grace, progress, and warm laughter,

Roger

It's going to be fascinating to see the products and cottage

industries that emerge to serve the raw/living foods community, as

our numbers inevitably grow.

Will love to see an application such as you describe.

I can see one of these attached to the rail of a sailboat.

 

Not sure if any dehydrating could be done when its actually raining

or extremely humid outside (is there such a thing as a " moisture

filter " that could be effective?), but perhaps it could still be used

for warming foods up.
