Our Services

1 - Field Production

Production quality from the farm to final product: we work in every detail in order to guarantee the best quality for our products. We select especially which seed to sow for each farm, also start making quality tests to the seeds before sowing.

2 - Harvest

Harvest control: during harvest, we conduct standardized tests of mechanical damage caused by the harvester to avoid damage to the minimum. This is critical to ensure the quality for seeds and popcorn (mainly the expansion). Traceability: is to truck the merchandise collected from the batch of origin through records with documentation to back it up.

3 - Reception and conditioning

Beginning the storage in the plant: We use cleaning screens in reception to remove impurities and to allow for proper aeration of the grains. Special mechanism to slower transport speed to decrease the mechanical damage of cereal to a minimum. Automated aeration system (stabilization). The plant is equipped with axial type aerators in flight silos and centrifugal type aerators in the screening floor silo. It has a design that allows uniform distribution of the air in the total volume of stored grains. We only use natural air to treat the moisture and temperature. The automated aeration system establish a uniform temperature of 13°C, point at which the biological activity of bacteria and fungi minimizes. For safe storage, we work with moisture between 12° and 14%. Periodically make quality test in our lab during the different stages of process and storage.

4 - Cereal process

Conveyor belts transportation system: The plant has only a conveyor belts for handling grains. Mechanical damage is practically zero. No contamination: it minimizes the risk of contamination of strange matters or grains of other cereals or oilseeds, the belts area easily clean without leaving a single grain in the extraction system. Introduction into the silo: Processing Capacity: 60 tons per day. We work closely with customers to ensure their products achieve the highest quality.
