Food Solutions New England (FSNE) is a regional food systems learning-action network dedicated to advancing a sustainable New England food system. The FSNE network is organized around four interrelated activities:
A New England Food Vision, a bold vision that calls for our region to build the capacity to produce up to 70% of food that is produced in an environmentally and socially sustainable manner, that promotes health and is accessible by all New Englanders by 2060; New England state food planning initiatives; annual New England food summits and topical workshops; and related analysis, communication and visualization.
The UNH Sustainability Institute serves as the backbone organization for FSNE. Since its inception in 2006, FSNE has advanced its mission by linking a common agenda, shared measurement, continuous communication, and synergestic activities.
My understanding is that the screen size is very important so that after the dehulling process both the hull and the grain are able to fall or push through the screen and then are carried by the air flow up and out of the housing to the cyclone separator. There are details about the vacuum setup in the engineering drawings and notes posted. I think it was 2000cf/min and a 2hp suction fan.
My understanding is that even with the large commercial systems the process is fairly manual for re-running unhulled grains - and requires some fine tuning and attention to varying crop conditions. larger capacity seed cleaners and number of screens both prior to and after hulling will help reduce the labor of the process to get a quality finished product and reduce loss. Like with most of this kind of processing sizing and sorting for consistency helps prior to processing. That is why I think the fanning mill is so important.
