Yes it can be done I'm sure but it wouldn't be suitable in this case. The food product that is being made here is unique in the market and requires dehydrating in a controlled manner. My client has been developing his methods for some time and has tried various commercially available machines, some of which have cost large sums. None of them have performed any where near as well as his ' Heath Robinson' machine. He has been testing it for some time with a bespoke monitoring system which guess what, he designed & built himself. He could bore you for many hours with graphs & data & stuff...Why? They do it with fridges, freezers and propagators, why not dehydrators?
