Avocado Oil New Zealand, based in Te Puna, makes Avo-pure, an avocado powder exported to the United States, Japan, China, and Australia. The powder is rich in potassium, fiber, and vitamins. To make it, the company uses a spray dryer at Waikato Innovation Park.

The process starts by heating avocado to remove oil. This leaves a black, burnt residue inside metal containers. The pulp then goes through more steps before spray drying. Cleaning the residue was hard. Quality Manager Alex Fernandez tried high-pressure water and different chemicals, but nothing worked.

One day, Alex read an article in Food Technology about Tenax, a cleaning product. He visited the Hygiene Technologies website and decided to try it. Lincoln Field from Hygiene Technologies came to see the problem. “It was one of the hardest cleaning jobs we had seen, but we believed Tenax would work,” Lincoln said.

Alex tested Tenax at different strengths. He found a mix that softened the residue so it could be removed with a water blaster. The steps were simple: spray Tenax, wait 20 minutes, rinse with warm water, then water blast. The result? “It works!” Alex said. “We had been searching for a solution for a long time.”

Tenax thickens when diluted to the right level. This helps it stick to surfaces better than foaming cleaners. It wets the surface and dissolves the soil. Tenax stays on vertical and flat surfaces longer, giving more cleaning power. This means less manual work, less hot water, and less time.
