Heat transfer for making coconut sugar
I'm currently helping out at a fair trade company in the Philippines who make coconut sugar. Part of the process requires the heating and stirring of the sugar at six different stations running in columns of two. They use an external heat source (to keep smoke away from the product) of burning saw dust (cheap and readily available to them) to heat the pans. The problem they have is while the first two stations receive ample heat the next two receive less and the last two less again. I have not visited the site (but will do) and have only had it explained to me. I was thinking about using blowers to transfer more of the heat to the other stations, but not sure how to go about it or even if its a viable options. Your thought on this would be much appreciated.
BTW this is my first ever post on any forum so sorry if its not quite right or missing some obvious details. Please let me know if you require more info.
