Ice Box Auger

Augers are famous for jamming at the entrace to the auger housing.   Where the auger enters the housing, the turning auger creates an active pinch point that likes to pull the transported material into its maw and get stuck.   Here's how ice box augers solve the problem.

 

The ice box solution is to simply include a short section of tube which turns with the auger before transitioning to the stationary part of the housing.  This eliminates the active pinch point.  Yes there is still a constant "V" where the auger meets the housing, but this is not constantly "closing" like a pair of scissors.  It is reduced to just static shape passing through the material, not an active grabber of material.

 

Once the material is in the turning tube, you can transition to the stationary auger housing with the stationary and turning tube butted end to end.  There will be no pinch here, as you will be smart and use the same size tube for both the turning and stationary parts of the auger housing. 

 

This scenario is shown in partial in the ice box pictures below, but you will have to extrapolate a bit for a complete biomass moving solution.  There is also some interest add-on shapes for how to get the material into a delivery tube, without also leaving the tube open for constant flow.

 

(thank you mom mason for the photo op of her ice box).
