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 elevated 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.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 238 words
An apparatus for continuously hydrolyzing keratinaceous material comprising a first vessel, entry means connected with the said first vessel for continuously delivering the material into the same, agitating means provided in said first vessel for simultaneously violently agitating and moving said material through said vessel, said agitating means being rotational and capable of revolving at speeds of between about 150 to 350 rpm, heating means operatively associated with said first vessel and capable of heating any material traversing therethrough up to a temperature of less than 212° F. and without any significant build up of pressure within said vessel, a second vessel, pump means interconnecting between the said first and second vessels and when operative capable of continuously transferring the fluidized material from the first said vessel into the second said vessel, another agitating means provided in said second vessel and capable of revolving for agitating the material pumped therein, another heating means operatively associated with the said second vessel and capable of heating the material traversing therethrough to a temperature of between 265° F. to 365° F. while creating a pressure therein of between about 25 to 150 psig, said pump means circumventing the passage of any second vessel generated pressure into the first said vessel, and another pump means connecting with the said second vessel and when operative providing for the continuous discharge of the now hydrolyzed material and some pressure from the said second vessel.
Claim 2
Independent Claim 238 words
An apparatus for continuously hydrolyzing keratinaceous material comprising a first vessel, entry means connected with the said first vessel for continuously delivering the material into the same, agitating means provided in said first vessel for simultaneously violently agitating and moving said material through said vessel, said agitating means being rotational and capable of revolving at speeds of between about 150 to 350 rpm, heating means operatively associated with said first vessel and capable of heating any material traversing therethrough up to a temperature of less than 212° F. and without any significant build up of pressure within said vessel, a second vessel, pump means interconnecting between the said first and second vessels and when operative capable of continuously transferring the fluidized material from the first said vessel into the second said vessel, another agitating means provided in said second vessel and capable of revolving for agitating the material pumped therein, another heating means operatively associated with the said second vessel and capable of heating the material traversing therethrough to a temperature of between 265° F. to 365° F. while creating a pressure therein of between about 25 to 150 psig, said pump means circumventing the passage of any second vessel generated pressure into the first said vessel, and another pump means connecting with the said second vessel and when operative providing for the continuous discharge of the now hydrolyzed material and some pressure from the said second vessel.
Claim 3
Dependent Claim 58 words
The invention of claim 1 and wherein said first vessel is jacketed, said jacketed vessel capable of generating jacket temperatures therein of between about 265° F. to 380° F. by means of a jacket pressure of between about 25 to 200 psig to effect the heating of the material passing through said first vessel not above 212° F.
Claim 4
Dependent Claim 43 words
The invention of claim 1 and wherein said agitating means operatively associated within the first said vessel comprise paddle means, and said paddle means when revolving capable of violently agitating the material passing therethrough while simultaneously effecting their movement through the said vessel.
Claim 5
Dependent Claim 44 words
The invention of claim 3 and wherein said another agitating means operatively associated within the said second vessel comprises paddle means, and wherein said paddle means are capable of violently agitating the material passing therethrough while effecting material movement through the said second vessel.
Claim 6
Dependent Claim 15 words
The invention of claim 3 and wherein said pump means comprises a rotor type pump.
Claim 7
Dependent Claim 36 words
The invention of claim 3 and including jacket means formed upon the said second vessel, the said jacket means when subjected to heat effecting an increase in temperature and pressure development within the said second vessel.
Claim 8
Dependent Claim 14 words
The invention of claim 6 and wherein the material being continuously hydrolyzed comprises feathers.
Claim 9
Dependent Claim 18 words
The invention of claim 7 and wherein the feathers are continuously traversing through the apparatus during its operation.
Claim 10
Dependent Claim 66 words
The invention of claim 8 and wherein the pump means interconnecting between the first and second said vessels when operative preventing the escape of the pressure built up in the second vessel to the first said vessel, while the second said pump operatively associated with the discharge of the second said vessel continuously releases the fluidized feathers and some pressure from the same during apparatus operation.
