High velocity compressed air blow-offs are a viable means of drying or de-watering parts in many applications. They are especially useful if parts don’t need to be “super dry” (as completely free of water) or if there is a requirement to remove “excess” water from a part prior to final drying using another means such as hot …
In the previous blog, I promised that we would further explore Conductive vs. Radiant heating as a way to dry parts in this blog. I can think of no better way than by using a couple of illustrations showing the flow of heat in both cases. Hot Air Drying – Conductive In a hot air …
It should be clear by now that heat plays an important role in drying. Delivery of heat to a drying system is critical and can be accomplished in a number of ways. Today’s blog will explore two options for heat delivery – conduction and radiation. Conduction seems to be the “go to” when it comes …
If you have deduced from the preceeding few blogs that heat is one of the major factors in drying, you are right. But before we talk more about heat, let’s “set the stage.” Heat is that stuff that increases temperature of a substance when added and reduces temperature when absorbed. Temperature is the level of …
In reading the last couple of blogs it would be easy for the reader to come to the conclusion that the addition of heat is all that is needed to dry things. It would be nice and easy if that was the only consideration. The fact is that evaporative cooling is working against us in …
In the preceding blog, we learned that relative humidity of air is affected by temperature. Although I really didn’t say it, I’m sure readers have come to the conclusion that lower relative humidity will result in air which is “hungry” for water. Air that is at a low relative humidity, then, is beneficial to drying. …
I first talked about drying a long time ago in the blog called “Don’t Forget Drying.” In that blog, I stressed the importance of drying as a part of the cleaning process. In some cases, changes in the cleaning process can affect drying but, for now, let’s just concentrate on drying. Drying simply means removing liquid …
