Production process of fertilizer composition from animal blood with high levels of organic carbon and free natural amino acids, product obtained and use

PRODUCTION PROCESS OF FERTILIZER COMPOSITION FROM ANIMAL BLOOD WITH HIGH LEVELS OF ORGANIC CARBON AND FREE NATURAL AMINO ACIDS characterized in that comprising the steps of selecting the raw material from the group consisting of blood meal, in natura animal blood, and a mixture of in natura animal blood with blood meal;

• A. selection of raw material from the group consisting of
• (i) blood meal,
• (ii) raw animal blood, and
• (iii) mixture of raw animal blood with blood meal;
• B. preparation of the selected raw material, said preparation corresponding to the raw material defined and chosen from the group consisting of
• B1. dissolution of blood meal with a minimum crude protein content of 92% (i) with water, in the proportion of 60% to 70% of water and 30% to 40% of blood meal, said dissolution being processed in the hydrolysis reactor(s),
• B2. sieving/filtration of in natura animal blood (ii) through a 5.0 mm sieve, without adding water and transferring to the hydrolysis reactor(s), and
• B3. dissolution of blood meal with a minimum crude protein content of 92% with fresh blood sieved through a 5.0 mm sieve (iii) in the proportion of 60% to 70% of in natura blood and 30% to 40% of blood meal, said dissolution being processed in the hydrolysis reactor without the addition of water;
• C. emulsification of the solution obtained in (B) with activation of the stirrer, subsequent heating of the solution and activation of the emulsification pump recirculating the mixture inside each hydrolysis reactor;
• D. enzymatic hydrolysis, the reaction parameters being independent of the raw material used and selected from the group of configuration sets consisting of
• D1. use of alkaline protease enzyme, added to each hydrolysis reactor in a proportion of 0.5% in relation to the total mass to be processed under a temperature of 40° C. in the reactor, said temperature being maintained between 40 and 70° C. and pH maintained between 8.00 and 9.00, said reaction medium being maintained for 1 to 5 hours, preferably for 3 hours,
• D2. use of acid protease enzyme, added to each hydrolysis reactor in a proportion of 0.5% in relation to the total mass to be processed under a temperature of 40° C. in the reactor, said temperature being maintained between 40 and 65° C. and pH maintained between 2.50 and 4.50, said reaction medium being maintained for 1 to 5 hours, preferably for 3 hours,
• D3. use of neutral protease enzyme, added to each hydrolysis reactor in a proportion of 0.5% in relation to the total mass to be processed under a temperature of 40° C. in the reactor, said temperature being maintained between 40 and 60° C. and pH maintained between 6.50 and 7.50, said reaction medium being maintained for 1 to 5 hours, preferably for 3 hours,
• E. enzyme inactivation by raising the process temperature in each hydrolysis reactor to 90° C. for a period of 30 minutes;
• F. sterilization of the product obtained while maintaining the heating in (E), of 90° C., for another 30 minutes;
• G. product filtration and transfer to acidification tank;
• H. product cooling up to 70° C. in an acidification tank;
• I. stabilization of the product under temperature reduction to values below 70° C. and at a pH of 2.50 to 3.50;
• J. addition of preservatives, antifungals and antioxidants;
• K. storage in stainless steel material tanks;
• and
• L. packaging in 50-liter drums, 1,000-liter containers or bulk shipping in tank trucks.
