DESCRIPTION:
BRIEF SUMMARY
A method for producing high-grade fertilizer is described in Austrian Pat. No. 344,210, wherein food residues, particularly press residues from wine production, are arranged in a loose form and, for example, by rearranging the residues, are subjected to an aerobic decaying process in the loose state, possibly with the utilization of the generated heat and CO.sub.2, and wherein, after the decaying process has ended, a division of the resulting substance is effected by sieving and the fraction containing the pips is further processed, for example, crushed and subjected to a post-decaying process. The decayed crushed pips have been found an extremely effective fertilizer.
It is the object of the invention to further develop the known method, wherein the decayed crushed pips are again divided into fractions. It has been found that the resulting fractions have different properties which can be utilized for specific purposes.
Therefore, the invention relates to a method for producing high-grade fertilizer and useful side products from pips, wherein, after the aerobic decay of press residues from wine production, the pips are separated from the decay products by sieving, are opened up by crushing and are subjected to another aerobic decay, and which is characterized in that the components of the decayed crushed pips are divided into three fractions of different particle sizes by means of sieving, the fine fraction of which contains predominantly or almost exclusively humified seedling and humified nutrient tissue of the grape seed, the coarse fraction consists predominantly of thirds and quarters of pip walls and the middle fraction includes smaller pieces of the pip walls. A sieving method has been found useful wherein the components of the decayed crushed pips of a size less than 0.5 mm are assigned to the fine fraction, those with a size of between 0.5 and 1.0 mm are assigned to the middle fraction and the larger components are assigned to the coarse fraction. For many purposes, it has been found that the coarse fraction is capable of performing its task even when it had earlier been leached with water. This liquid represents an excellent liquid fertilizer.
The invention further relates to certain types of application of the fractions obtained in accordance with the invention.
When the decay of the crushed pips described in Austrian Pat. No. 344,210 has subsided, the cold material is sieved in accordance with the invention. For this purpose mesh sizes of 0.5 and 1.0 mm have proved useful. The separating process is performed by means of sieve drums which are slightly inclined and are used in many technical applications.
It has been found that the fine fraction represents a high-grade fertilizer because it contains large quantities of microorganisms. When the fertilizer is introduced into the ground, the microorganisms continue to perform their function and gradually contribute to the mineralization of the fertilizer. Only microbial processes set free the organically bound nitrogen and make it available for the plant roots. This fraction consists predominantly or almost exclusively of the humified seedling and the humified nutrient tissue of the grape seed and this fraction is therefore particularly suitable as fertilizer for plant saplings or potting soil.
The portion of the fine fraction is about 18 to 20% by volume. The portion of the middle fraction varies between 20 and 30% by volume and consists predominantly of small fragments of the pip wall. The coarse fraction represents 50 to 62% by volume and consists of large fragments, such as, thirds or quarters of pip walls. Residues of the humified seedlings and nutrient tissue which could not be completely separated during the sieving process adhere to the cavities of these larger particles. When the coarse fraction is leached by means of water, these humified residues are transferred into the liquid. These residues contain many phytohormones.
The finely crumbly fraction contains all growth substances, nutrients and reserves which a seedling needs for germinati
