Successful customer evaluations have brought forward the launch of Zayndu’s Aurora Z25, which uses 'activated air' to disinfect seeds without water or chemicals. The company is also extending its ‘try before you buy’ offer to enable customers to see the benefits of the complete system running in their own facilities. The new addition to the Aurora series offers increased capacity and additional resilience and is being launched at CEA 4.0 on the 6th and 20th May 2022.
Seed pathologist Dr. Alberto Campanaro heads up the R&D facility at Zayndu and says that the increased capacity machine has been requested by customers following evaluations with their own seed.
“So far, the biology team has used our first machine, the Aurora Z10, to treat 60 varieties across 23 different plant species. The seeds are disinfected, and the pathogen load, germination rate, and vigor are compared with the untreated seed.”
“Customers have reported an increase in germination rate of up to 20 percent. However, several organizations have also told us that the 10-liter capacity was insufficient for many controlled environments.”
“Working with these end users has been invaluable and has enabled us to optimize the process, validate industry demand, and co-design the larger machine.”
The Aurora system offers a chemical-free, water-free alternative way to disinfect seeds. The seeds are placed in a sealed drum, and an electric current is introduced, splitting the air molecules into reactive oxygen and nitrogen species (RONS). This ‘activated air’ destroys bacteria and fungi, leaving just clean seeds and fresh air.
Scientific studies have shown that the RONS change the surface of the seed coat, which increases water uptake during germination.
Alberto continues: “The demand for seed evaluations from potential customers has exceeded our expectations and is producing some fascinating results, particularly around optimizing the exposure to activated air. We are seeing greater consistency in germination, faster germination times, and improved plant development.
“We are looking forward to discussing these findings at CEA 4.0.”
The company is offering the Z25 to customers for assessment to allow them to see the benefits in their own environment and to work with Zayndu scientists to optimize the protocol by species and variety.
