Methodology for Producing the "San José Formula No. 11" and Balanced Feed/Concentrates for the Agricultural and Livestock Sectors.

Step 1: Chopping of forage and biological material.
Step 2: Pressing of biological material.
Step 3: Pelletizing of biological material.
Step 4: Distillation of biological material.
Step 5: Cooling and drying of pellets; packaging of distilled *biol*.

This methodology describes a circular-economy, zero-waste agro-industrial process in which biological material (such as cut grasses, forage, or residual biomass) is processed to yield two high-value products: a solid concentrated feed (pellets) and a liquid biofertilizer or biostimulant (distilled *biol*).

The optimization and technical workflow for each step of the San José Formula No. 11 are detailed below:

Process Flow: San José Formula No. 11

Step 1: Chopping of Grass and Biological Material. Objective: To reduce the biomass particle size in order to increase the contact area and facilitate juice extraction. Operation: The forage grass (e.g., Maralfalfa, Elephant grass, Cuba 22) and complementary biological material are fed into an industrial chopper. Specification: A particle size of between 1 and 3 cm is targeted. Uniform chopping ensures efficient subsequent pressing.

Step 2: Biological Material Pressing. Objective: To mechanically separate the solid fraction (bagasse/fiber) from the liquid fraction (nutrient-rich cell juices). Operation: The chopped material passes through an extraction press (commonly a screw press or roller press). Separation results: Solid Fraction: Pressed fiber with lower moisture content, ideal for pelletizing. Liquid Fraction: Green juice or soluble extract, rich in sugars, minerals, and native microorganisms.

Step 3: Pelletizing Biological Material (Solid Line). Objective: To compact the solid fraction, transforming it into a high-density balanced feed that is easy to transport and has a long shelf life. Operation: The fiber from the press is metered (vitamin premixes, minerals, or molasses can be added here if the formula requires). It passes through the pelletizer, where friction and pressure (and sometimes steam) bind the material together as it is forced through a die. Result: Highly digestible pellets for the livestock and agricultural sectors.

Step 4: Biological Material Distiller (Liquid Line). Objective: To stabilize, concentrate, and purify the liquid fraction extracted in Step 2, converting it into high-quality *Biol* (liquid organic fertilizer). Operation: The liquid undergoes a controlled distillation/evaporation process. This removes excess water, concentrates organic nutrients (nitrogen, phosphorus, potassium, and amino acids), and ensures the elimination of any pathogens through heat. Result: A concentrated, standardized *Biol* free from harmful bacteria.

Step 5: Cooling and Drying of Pelex and Packaging of Distilled Biol. This is the finishing and quality control stage where the two final products definitively diverge: For Pelex (Solid Feed): The pellets emerge from the pelletizer hot and with residual moisture. They pass through a counter-flow cooler/dryer to stabilize them. This prevents fungal growth during storage. Subsequently, they are bagged in heavy-duty sacks. For Distilled Biol (Liquid Fertilizer): The distilled and cooled liquid is dispensed into hermetically sealed plastic containers (jugs, drums, or IBC totes), ready for foliar application or fertigation on pastures or crops.
