Dear Neal

how is the extrusion done, what materials are used and is the product
sterile ?
We mixed the separated solids of hog manure with soybeans to add lubricity for the extrusion process. Then we passed the material through an Insta-Pro extruder at about 280F. The resulting material was a homogenous and highly digestible and nutritious blend of the sterile input ingredients.
 
I should add that the extruded feeds were readily accepted by the dairy calves we used in this experiment but not any more than the raw hog manure was accepted by them. Hog manure, after solids separation, is we received by cattle as a feed ingredient. The purpose of extrusion was to sterilize it.
 
I am of the opinion that fermentation would result in similar biosecurity and could be just as palatable and nutritious with much less expense.

thanks for the info Neal.

What is most interesting for me is the ability to convert a waste that you cannot imagine to be a resource esp. from the hygienic point of view.

This basically also mean that restaurant wastes could be used.

About 20 years ago I say a demo of an extruder to extract a paste from young wheat leaves and the idea was to use it as a human food concentrate.

I searched images for "Insta-Pro" and got a number of links.

When it comes to integration, I am building a scenario of a commercial pig operation (based on commercial feed) and then a zero-graze cattle or goat operation that extrudes pig manure + grass/straw + bean as ruminant feed. Straw would come from growing cereals. 

I understand that an extruder also acts like a exploder which would probably split the ligno-cellulose of the straw and therefore making it more digestable.

Neal:
do you know of any business operations that use Insta-Pro at a farm level in the USA ?

We have an Insta-Pro model 600 at our Indiana site. It is capable of extruding about 600 lb of soybeans or other material per hour. It is considered an R&D model and not actually designed for extensive operations. It is the size found at many university research facilities.
 
We obtained it from a farmer in northern Indiana who used it to process soybeans for his livestock.  Although this extruder is designed to be powered by a large electric motor we chose to substitute a 100hp diesel engine salvaged from a small truck.  This allows us to demonstrate how soybeans can be extruded with an engine powered by soybean oil.
 
Soon we will be powering this unit on wood gas produced by a gasifier on site using sawdust fuel. We will continue to use about 10% of the previous fuel ration as before with the wood gas providing 90% of the power. This will show that sawdust, or rice hulls, or beef manure, can be used to power an engine along with a minor amount of liquid fuel.
 
We already power an 80hp gasoline engine totally on wood gas.  It produces the heat, hot water and electricity for our Texas R&D facility from sawdust.
