Vacuum packaging of ultrafine powders
I’m looking for general advice on existing technologies/suppliers that specialize in vacuum packing of ultrafine powders. We run a process producing fine powders (D10 =2 micron, D50 = 7.5micron, D90 = 12 micron). For all intents and purposes, it can be considered akin to carbon black; quite light and fluffy. Our customers desire that we provide our product in 15kg,...
Equipment for toasting soybeans?
What information do you have about toasting soybeans and suitable equipment? The aim is to lower the levels of urease and TIA in the soybean to make the product better adapted to poultry and pigs.
Minimum conveying velocities for various particle types
I am currently in the process of designing a dust collector. One of the first steps involves specifying the correct minimum conveying/pickup velocity at the inlet of the hood. It is to be used in the baking industry and can see anything from different flours, sugar, salt, seeds, whole buns, etc. After a couple hours of research I’ve realized it...
What Do Chutes And Hoppers Do In Pneumatic Conveying Systems?
A pneumatic conveying system can’t function without the combination of chutes and hoppers – they are integral and critical components that are inseparable because they act as a giant funnel that helps to get your material into your system.
What Is Saltation Velocity?
Saltation velocity is the speed below which particles being conveyed through a pneumatic conveying system lose suspension and begin to deposit at the bottom of horizontal pipelines.
