Processing, storage and export of specialty grains

In Natural Crops we are dedicated to the processing of chia and special grains with cutting edge technology with the highest standards of quality and safety internationally certified, with responsibility and efficiency in the results of our products.

We have a real capacity of 2 ton/hour in finished product, packaging with in-line metal detection and bagged finished product.

Stage 0: Control of personnel hygiene - sanitary filter

All personnel go through this point before entering the plant, where they clean and disinfect their hands with liquid detergents and alcohol, put on the corresponding PPE such as the mask and chinstraps, and put on the safety helmet.

The plant supervisor inspects the personnel with the corresponding clothing, the use of the appropriate PPE and with complete cleaning and disinfection in order to start their activities within the plant.

Stage 1: Pre-Cleaning

Stage of the cleaning process in which major and minor impurities and weeds are eliminated from the chia, through the use of state-of-the-art technologies that guarantee compliance with the highest quality and safety standards worldwide. The processing capacity is 10 tons of chia per hour. This area is separated from the clean area but is connected directly to the next stage through conveyor belts without human handling of the product.

Stage 2: Sorters

The product received from the previous one is classified with the highest technology eliminating impurities and weeds of similar size as the chia.
The process has an integrated dust extraction system, thus ensuring the safety of the product and the well-being of the operators.

The equipment is made of stainless steel and the conveyor belts are food grade.
It has a processing capacity of 5 tons/hour of chia.

Stage 3: Densimetric tables

In this cleaning stage, the product from stage 2 is received through a vibration and ventilation system, separating by gravity the impurities and weeds of similar weight to the chia. The process has an integrated dust extraction system, thus ensuring the safety of the product and the well-being of the operators.

The equipment is made of stainless steel and the conveyor belts are food grade.

Stage 4: Banishers

The product from stage 3 is received to remove 100% from lumps and stones through the magnetic separation process,.

The process has an integrated dust extraction system, thus ensuring the safety of the product and the well-being of the operators.

The equipment is made of stainless steel and the conveyor belts are food grade.

Stage 5: Bagging

We receive the product from stage 4 in a special hermetic area where the received product passes through a stainless steel temporary storage hopper with magnets and a first vertical in-line metal detector, with a detection sensitivity for ferrous and non-ferrous metals of 1.5 mm and stainless steel of 2 mm in diameter, bagging the product in different presentations according to the customer's requirements, complying with the highest international quality and safety standards.

Step 6: Detection of metals in finished product

We have a second equipment for the bagged product of stage 5 with a detection sensitivity for ferrous and non-ferrous metals of 1.5 mm and stainless steel of 2 mm in diameter, this is validated prior to use through test bodies.

The bagged product from stage 5 is tested by a second metal detector to ensure the absence of metals and the safety of the bagged product.

In case of detection of a foreign body, an audible and luminous alarm is activated in the equipment, cutting the product flow. The detected bag is separated from the batch and sent back to the start for reprocessing.

Stage 7: Pre-chambers

Once the product is packed with the export conditions, the finished product is moved to a prechamber where it awaits the physical laboratory analysis to be stored in cold chambers with controlled temperature and humidity.

Stage 8: Laboratory validation of finished product quality

Our infrastructure has a laboratory for physical analysis with highly qualified and trained personnel for this purpose. Laboratory staff samples and analyzes the finished product, validating that the product meets the quality and safety specifications, releasing it for transfer to cold storage and subsequent marketing.

Stage 9: Cold chambers

We have an infrastructure of 2500 m2 distributed in 6 cold chambers, each one with a storage capacity of 800 tons of finished product, complying with international storage standards. They have a temperature and humidity system controlled by digital devices that show both parameters constantly. Grains and seeds can be stored with temperatures from 8ºC and relative humidity of 40%.

Each lot is coded according to process traceability and product analysis, internally in the chambers there is a separation for organic and conventional products to avoid cross contamination.

Stage 10: Loading and dispatch of containers

Once the product has been released according to the analysis and international parameters required by the customer, the container is loaded:

  • Cleaning, disinfection and container lining.
  • Installation of dehumidifiers
  • Metal detector installation and verification
  • Bag-by-bag verification by metal detector, loading into container and sealing.
