Yamato GWS410 Organic Solvent Washing Unit

New spray drying technology is fundamentally changing the cannabis industry, with cannabis micro-powder positioned to be the most in-demand product in the next five years. Early adopters of new spray drying technology will benefit most. 

The GWS410 is the world’s first water-based solvent neutralizer designed primarily for spray dryers. It traps contaminants in solvents by using tap water or alkaline solution at atmospheric pressure and room temperature, and can help your business grow by creating premium cannabis powder.

GWS410 is designed with a washing tank — when solvent vapor enters the tank, sprayed water adheres, cleans and neutralizes solvent particles, before returning to the bottom of the chamber. It traps contaminants in solvents by using tap water or alkaline solution at atmospheric pressure and room temperature.

Spray drying allows manufacturers, distributors, retailers and growers to create products that last longer on shelves, cost less to transport and mix better with consumer products than oils. Benefits of using the GWS410 to create premium cannabis powder include:

Lower shipping costs

Spray drying reduces your product’s weight and volume, making it more cost-effective to ship (and leading to huge savings over time)

Easier storage

Powder is astronomically easier to house than oil.

Longer shelf life

The average shelf life of a spray dried product is over one year. 

Absolute solubility

Water and oil don’t mix. Cannabis powder mixes into edibles and drinks better.

A more consistent product

Spray drying makes it easier to produce standardized, cannabinoid-infused products.

Fast-acting, predictable, and repeatable experiences

With an onset of 20 minutes, effects that can last up to 4 hours, and a consistent product, customers get a more predictable experience.

More eco-friendly choice

From production to shipping, cannabis powder is proven to be a more eco-friendly alternative.

Lab-scale process validation

Produce consistent results for customers, and ensure your product development can keep up with demand for new products with scalable, spray drying technology.
