Drying the leaf is only part of the process. What happens after drying is just as important to the quality of the powder you receive.

This post follows our powder from the mill to a palletised carton, ready for export.

Step 1: Milling

After gentle hot-air drying on our Perry continuous belt dryers, the dried leaf is milled into a fine powder. Our standard particle size is around 70 microns.

A fine, even particle size matters to formulators. It helps the powder disperse in water, gives a smoother texture in drinks and flows well through capsule and tablet equipment.

Step 2: Separation and screening

Milled powder passes through our stainless steel cyclone separator. The cyclone uses air flow to separate fine powder from the air stream. The powder is then screened to keep particle size consistent.

Step 3: Testing

Every batch is sampled and tested before it is released. Results are recorded on a certificate of analysis, which is available with every shipment.

Testing confirms that the batch meets its specification. Typical results include moisture, particle size and microbiological quality.

Step 4: Filling

Powder is filled into a food grade liner inside a 20kg carton. This is our standard packaging for all seven products.

Each carton is labelled with the product name and batch number. This links the carton directly to its harvest, drying and milling records.

Step 5: X-ray screening

Packed product goes through X-ray screening. This detects foreign material that should not be in the product, such as metal, stone or dense plastic.

X-ray screening adds another layer of protection for our customers and their consumers.

Step 6: Palletising for export

Cartons are stacked on pallets, stretch-wrapped and strapped for transport. Pallets are stored on warehouse racking until dispatch.

We prepare the export documentation each market requires. Our customers are in New Zealand, Australia, Southeast Asia, Europe and the United Kingdom.

The systems behind the line

Our packing line operates under a HACCP-based food safety plan. HACCP stands for Hazard Analysis and Critical Control Points. It is a system for identifying food safety risks and controlling them at key steps in the process.

The whole operation also sits inside our BioGro certified organic system (#5690). This means organic product is kept separate and protected from contamination at every stage.

Traceability from carton to field

Because we grow, dry, mill and pack our own crops, we can trace any carton back through every step. We know the batch, the processing date and the farm the leaf came from.

For international buyers, this traceability supports your own quality and compliance systems.
