Rooted on the Bolivian plateau, Natural Harvest S.R.L built an integrated chia seed processing plant with full sets of customized precision sorting machinery, forming a standardized closed-loop production line from farm direct sourcing to finished goods storage. Our exclusive multi-stage purification process including density grading and gentle polishing removes all inferior seeds and impurities, delivering plump, nutrient-intact chia seeds meeting European & American export cleanliness standards.

Raw Material

Freshly harvested raw chia seeds are introduced into the process.

Screening and Classification-Based

Cleaning Equipment

The equipment is equipped with four layers of sieves featuring different pore sizes. The upper and lower sieve layers remove impurities of varying diameters from materials, while the two middle layers separate materials by particle size. After processing by this equipment, over 95% of impurities in the materials can be substantially eliminated.

Rotary Flat Screen Cleaning Equipment

Removal of impurities similar in size to the material: this process relies on the principle that lighter impurities rise to the surface during rotary motion, allowing them to be evacuated from the top layer and effectively removed.

Quipment For Removing Stones From Chia Seeds

Using the principle of specific gravity, impurities heavier than chia seeds‑such as soil clods and metal fragments‑are removed.

Precision gravity and air-jet sorting equipment

Based on traditional specific gravity separation technology, this equipment incorporates a scale‑like ventilation design, making it the most effective machine of its kind currently available. During the vibration process, it utilizes airflow from these scale‑like openings to separate materials based on specific gravity, effectively removing impurities and immature grains.

Equipment for removing metallic substances from chia seeds.

This equipment operates on the principle that the metal becomes magnetic when energized. Upon activation, it generates a powerful 20 000‑Gauss magnetic field to capture magnetic substances present in the material; the captured material is released when the power supply is cut off. Combined with a vibration function to eject magnetic impurities, this cyclic process enables the automatic removal of iron. The unit features 30 internal layers of metal mesh; as the material passes through these highly magnetic layers, even tiny metal particles with very weak magnetic properties are captured.

Automatic packaging machine with electronic scale

The automatic packaging machine with an electronic scale ensures precise dosing and a secure, airtight seal. Being fully automatic and requiring no manual intervention, it delivers neat, clean, and attractive packaging for chia seeds.

Robotic Palletizing Equipment

The robotic palletizing process requires no manual intervention; once the chia seeds have been packaged and sealed in precise quantities, the robot stacks them accurately according to predetermined weight and height specifications.

Finished Product Storage

The finished products based on chia seeds are neatly arranged in the finished‑goods warehouse.
