Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
82 words
In a method of preparing animal food pellets wherein cooked mash under atmospheric pressure is forced through a die, the steps of cooking said mash under superatmospheric pressure, reducing the pressure on said mash to atmospheric, radially forcing said mash through orifices of a rotating die to form deaerated rods of substantially uniform consistency across successive transverse planes and characterized by the substantial absence of fractures on the lagging side of the rod and thereafter transversely severing the rods to form pellets.
Claim 2
Dependent Claim
