Abstract
Abstract The invention relates to a novel method and apparatus to precipitate and preserve protein from the juice expressed from green leafy plants by coagulating the protein in the juice through an anaerobic fermentation process and apparatus. In addition part of the carbohydrate and non-protein nitrogen in the juice is converted into bacterial protein which increases the amount of protein obtained from the juice and particularly prevents oxidative destruction of cystine and methionine and thereby increases these limiting amino acids in the obtained protein.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
316 words
Apparatus for the extraction of juices from green plants and coagulating and preserving proteins in the juices, which comprises extractor means for receiving the green plants and expressing the juice therefrom, a substantially oxygen free anaerobic fermentation and preservation tank located adjacent the extractor means, a first conduit adapted to connect the extractor means with said tank and conduct the expressed green plant juices to said tank from the extractor means, said tank serving as a holding tank for storing the juices for a predetermined length of time so that the juices have an opportunity to ferment therein in an anaerobic atmosphere by utilizing the microorganisms carried into the juices from the leaves of the green plants on which said microorganisms are naturally resident to thereby lower the pH of the juices and form liquid silage containing a protein coagulum free to be separated from the liquid supplied from the juices and be deposited in the bottom of the tank, breather means connected to the tank and adapted to compensate for differential in pressures between the gases inside of the tank and the outside atmosphere to prevent the entry of air into the tank to maintain an oxygen free anaerobic atmosphere inside the tank, a second conduit adapted to be connected to the bottom portion of the tank to unload the protein coagulant from the bottom of the tank for use as a feed supplement, a plurality of conduit connections secured to the tank at different levels and selectively adapted to be connected to a third conduit to unload the liquid which collects in the tank above the protein coagulum to thereafter be used as a fertilizer or concentr ated to a feed supplement, pump means adapted to be connected to each of the respective conduits to increase the flow of material therethrough, and valves disposed in each conduit to control the flow of material therethrough.

Apparatus for the extraction of juices from green plants and coagulating and preserving proteins in the juices, which comprises extractor means for receiving the green plants and expressing the juice therefrom, a substantially oxygen free anaerobic fermentation and preservation tank located adjacent the extractor means, a first conduit adapted to connect the extractor means with said tank and conduct the expressed green plant juices to said tank from the extractor means, said tank serving as a holding tank for storing the juices for a predetermined length of time so that the juices have an opportunity to ferment therein in an anaerobic atmosphere by utilizing the microorganisms carried into the juices from the leaves of the green plants on which said microorganisms are naturally resident to thereby lower the pH of the juices and form liquid silage containing a protein coagulum free to be separated from the liquid supplied from the juices and be deposited in the bottom of the tank, breather means connected to the tank and adapted to compensate for differential in pressures between the gases inside of the tank and the outside atmosphere to prevent the entry of air into the tank to maintain an oxygen free anaerobic atmosphere inside the tank, a second conduit adapted to be connected to the bottom portion of the tank to unload the protein coagulant from the bottom of the tank for use as a feed supplement, a plurality of conduit connections secured to the tank at different levels and selectively adapted to be connected to a third conduit to unload the liquid which collects in the tank above the protein coagulum to thereafter be used as a fertilizer or concentr ated to a feed supplement, pump means adapted to be connected to each of the respective conduits to increase the flow of material therethrough, and valves disposed in each conduit to control the flow of material therethrough.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1, in which the first, second, and third conduits are flexible hoses.
Claim 4
Dependent Claim
81 words
The apparatus of claim 2, in which the third conduit is adapted to be connected to the bottom of the tank and to one of the conduit connections of the tank for circulation of the stored material from said connection to the bottom of the tank or from the bottom of the tank to said conduit connection for intermittent flow of the contents of the tank therethrough in either direction to mix the stored material to aid fermentation and remove foam.
Claim 5
Dependent Claim
59 words
The apparatus of claim 2, in which the third conduit is adapted to be connected to a first conduit connection and to a second conduit connection for flow of the stored material therethrough in either direction to effect rotation of the contents of the tank to aid in settling of the protein sludge to the bottom of the tank.
Claim 6
Dependent Claim
34 words
The apparatus of claim 4, in which the conduit connections are angularly slanted for increasing the effectiveness of the rotation of the contents of the tank when flow through the respective conduits is initiated.
Claim 7
Dependent Claim
129 words
The structure of claim 1, and a substantially oxygen free storage tank disposed adjacent to the fermentation and preservation tank, a fourth conduit adapted to connect the said storage tank to the preservation and fermentation rank, means connecting the pump means to said fourth conduit to control the flow of material therethrough, a plurality of conduit connections secured to the storage tank, and valved conduit means adapted to be connected to the conduit connections of the storage tank and to the conduit connections of the fermentation and preservation tank to conduit protein sludge from the fermentation and preservation tank to the storage tank and to effect unloading of the coagulated protein from the bottom of the storage tank and de-proteinized juice from the upper portion of the storage tank.
