1-8 lb. COOL DOWN  SYSTEM

This setup will allow the rapid cool down of up to 1-8  pounds of roasted coffee beans.  This is fairly easy to build, however, If this is something you would rather purchase.   I now offer this at my website for $99.99 when purchased with any coffee roaster - Does not include the 4 HP Shopvac Parts List>  

1. ShopVac 4 HP & up

2. 12 Inch 8 Qt. Colander 

3. 5 Gallon Container

4. 2 1/2 Inch Vacuum ....Hose with 2 ea. Hose ....Adapters

  

 

The Shopvac provides a very rapid flow of air through the cooling beans.  The colander fits nicely in top of the 5 gal. container and may be easily removed for cleaning. 
Faster Cool Down Means More Repeatable Roast Profiles. Some roasters also use a small water bottle to spray a fine mist onto the beans while cooling, this fine mist evaporates when cooling the beans.
Another advantage to this cool down setup is that the cool down exhaust may be vented out the door or window.
