Processor - with methanol condenser (GL design)

The [GL Processor is a design by Graham Laming, and has become the "de facto" standard for homebrew biodiesel production in the UK. The processor features built in dewatering and Methanol recovery capabilities, as well as protection against user exposure to Methanol vapour. The design also lends itself to a variety of production techniques.

Modern adaptions use a more powerful pump to drive the venturi (typically Clarke's TAM105) and employ inline heaters or a liquid level deadlock to reduce the risk of accidental explosive ignition of the Methanol vapour, caused by the element becoming exposed above the liquid level.
