Has anyone got any good ideas on preheating fat before pumping into an Appleseed type Processor? I process about 200 plus litres per batch .Living in western Australia so daytime air temp. quite often reaches mid to high 30 degrees celcius. so maybe a solar heater of some sort?

assuming your fat is in 20L tins you could knock up one of these in about 20 minutes:

Quick, simple, cheap and very effective!

Or with a little more effort, you could make one of these:

Or you could build one of these...
