The document was prepared as a training manual for a Zimbabwian project funded by the Austrian Embassy titled Establishment of a production, sales and consulting infrastructure for solar thermal plants in Zimbabwe.

Its a comprehensive manual covering many designs and processes which you will see in illustrations from other documents you have read over the years. The 110 page book contains descriptions of many different dryers as well as examples of many different crops and their dryers. It also presents a great deal of technical data on drying but even though the title of the project nothing about markets, packaging and selling.

Solar drying should be all the rage currently giving its potential to impact global food shortage and climate change – but we still seem to be where we were decades ago.

Thes is the case with this masters thesis, which presents a nice simple (two different levels of detail) explanation of the sugar cane process. It includes the two main juice extraction systems diffusion and milling in parallel, although I am not sure whether this occurs in often in practice.

I find the well structured approach, via six focus areas, and the simple first person language easy to read and absorb.

Its interesting that the heart of beer development outside of Europe could be argued to have started in the US moved to Britain and then back to the US and that the UK is now moving towards learning from the US.

This 3 or 4 page article is a very nice overview of the current status and of the history of how things developed in the US and the UK.
