Mill for Dehydrated Onions
By Moinhos Vieira – technical team
Moinhos Vieira manufactures industrial hammer mills for grinding dehydrated onions, serving everything from small operations to large-scale industrial processes.
Our equipment is successfully used for the particle size reduction of dehydrated onions, allowing different levels of grinding according to the needs of each process.
With extensive experience in industrial grinding, we carry out practical tests with dehydrated onions to evaluate equipment performance and help select the most suitable solution for each application.
