I have read some articles on home and commercial flake food preparation.It appears the main set-back is the procurement of a "dehydrator".
and I quote:
A commercial dehydrator is essentially a vacuum chamber with a heat source.
A number of folk have built home-made vacuum pumps from discarded refrigeration air compressors.I will enclose the link for this at the end.
A commercial dehydrator for buildings operates like an air conditioner.The cooling fins are usually slightly closer together to increase de-humidification.
A home unit could be a large sweet jar with rubber hoses fitted in the sealed cover for connection to the vac-pump.All the R&D I did on this system was to provide an affordable vacuum pump for inverted or tunnelled aquaria.However, the response from the U.S.A. and Canada as to other uses has been phenomenal.Home-made freeze driers for garden produce;injection moulding to name 2.
This was the link I originally supplied for anyone wanting to buid a simple cheap vacuum pump.There are other links detailing oil-top-up and electrical connections.http://www.youtube.com/watch?v=1Dv9uUL80NQ
