Yes, I am speaking of them, I've had numerous email exchanges with them and a 45 minutes phone conversation as well... I think he still has that up because he did do the work and if he ever gets paid he'll let them know what he found. I just wonder what other process they'll discuss at the convention. From my understanding, the main change they made was adding another evaporator before the spray dryer or turn up the heat in the current one. Although, I haven't spoken to someone in production at Xechem Nigeria, so who knows, they certainly might have figured something else out...
