hi,
i've been very interested in making my own unit so it's similar to the excalibur type. the racks should be easy to make, simply stretch wire mesh over a square frame. the box should be easy to either come by or make.
now i'm wondering how many racks a 60 watt bulb would work for and also is a fan necessary or can you just have some form of ventilation (drilling air holes etc)
i'll have to have a google again when i actually have the supplies but i'm always curious to get firsthand knowledge
i had a ronco dehydrator in the states, the round type, plastic with several stacking trays you had to rotate, not very keen on that, it made a mess and wasn't very efficient
i've done dehydrating in the lowest oven setting but again, not very efficient (though i do love my beetroot crisps, should make more of those soon) i'm curious, just how does the air cupboard drying work? |

thanks for that, i am considering it. since ours wouldn't have a fan in it i suppose this would be just as good and probably easier to clean.... i am expecting a big paycheck in a few days, hope they still have some left! |
I'm guessing the fan is included to ensure airflow and prevent mould???
It'd very easy to fit a computer fan. I've used computer fans in a similar type of project. You'd need to connect the computer fan to a twelve volt adapter, by stripping the wires and twisting them together. Be sure to rewrap the exposed wires with 'electricians tape'.
Computer fans are available in different sizes (generally between 8cm & 12cm). Again I'm guessing, but I'd have thought the smallest size would be fine. Maybe someone with a dehydrator could measure theirs? I'd situate the fan low on one side, with two or three 1" holes on the other for air to escape.
computer fans are widely available for under a tenner, either from computer shops or online. Here's an example of what I'm talking about:

Power adaptors are easy to come by also. Most if not all mobile phones, computer printers, battery rechargers, laptops use them. You may well be able to recycle one from a gadget that you no longer use. Here's an example:

The adapter is the plug looking thing, on the top-right of the photo.
I bought mine from a local computer shop. They cost about seven quid each.
I guess my only concern about a computer fan is that the through flow of air might be too great, which would result in one losing too much heat. But as I have no experience of building or using a dehydrator, hopefully someone else might be able to chip in on this? If it is a problem then it'd be fairly easy to baffle the fan and slow the airflow. |
