Abstract
Abstract An apparatus for effecting the continuous conversion of feathers, hair, and other keratinaceous material into usable products, including a first vessel, said first vessel being jacketed and capable of heating the material therein without subjecting it to pressure, and paddles disposed for violently agitating the material within the vessel while gradually traversing it therethrough, a second vessel, a pump interconnected between the two vessels and providing for the transfer of the now fluidized material from the first vessel and into the second vessel while preventing the escape of any second vessel pressure back into the first vessel, the second vessel being jacketed and capable of heating the fluidized and flowable material therein to elevate temperatures while agitating the same to effect its hydrolyzation, and another pump connecting with the outlet side of the second vessel to provide for continuous discharge of the now hydrolyzed material and some pressure while the second vessel continuously hydrolyzes additional incoming material while creating supplemental pressure in order to maintain the desired pressure and temperature therein.
