Drying technology

End-to-end solutions

We harness all edible portions of the plant, process them, and dry them according to customer needs.

Some customers want whole powder, a less soluble ingredient because the vegetable’s fiber is retained, which is suitable for certain market segments. Some are looking for juice powder, for products where solubility is important.

Based on the attributes our customers identify for their finished product, we match up our vegetable and the right drying technology to meet those requirements.

Drying methods up close

Spray drying

  • Extreme heat (200 - 300º C)

  • Carriers often used

  • Color, phytonutrient, micronutrient degradation

  • Spherical microstructure causes shelf life instability and oxidation

Drum drying

  • Extreme heat (110 - 160º C)

  • Color, phytonutrient, micronutrient degradation

  • Highly irregular / jagged dried microstructure

Freeze drying

  • Exposure to extreme pressures

  • Long drying times (32 hours) equals nutrient loss

  • Pretreatment with chemical inputs is common

  • Highly porous finished-product

Refractance Window drying

  • Low temp. drying, no carriers

  • No extreme pressures or chemicals

  • Microstructure is uniform and non-porous, which increases shelf life and reduces oxidation and microbial activity
