VOLCANO

Volcanoes are designed to operate at peak efficiently with minimum maintenance and minimum operating cost.

They come in the following sizes:
30 - 60 - 75 - 145 - 250 -500  Gallon Systems
For - 850 -1010- 1500 - 2610 Gallon Systems, please call us to order at 
(707) 535-0599 

All Volcano's utilize Cone Bottom Tanks for superior performance.

How the Volcano Work

The Cone Bottom directs all solids to the center of the tank, where the air is introduced. The Air bonds with the water and lifts the water to the top where it flows to the outward edge then it sinks to the bottom and restarts the sequence again and again.

Sediment Free Brewing 

Cone Bottom Tanks with Center Air Inject is the Key to a Sediment Free Brewing System.

 

The Volcano keeps all solids suspended and in constant motion. The solids are lifted by the high volume/low pressure air that is injected into the bottom center of the tank. This moves the material vertically through the center of the tank until it reaches the top and flows outward toward the edge. The material and water loses it velocity at the edge and sinks to the bottom center to start the cycle again and again.

Volcanoes have been extensively tested for Oxygen Levels, dissolved Solid Extractions and we constantly do Microscopic inspection of the final Tea Product.

We typical see the Oxygen Content of the Water increase to about 11.25 PPM within a 15 - 20 mins.

We have found no other methodology or technology that out performs the Volcano.

 

If you are looking for a brewer that is designed for long term commercial uses and demand  consistent top level performance the VOLCANO Series is the one for you.

Volcanoes ship via Truck to Commercial Site or Local Truck Terminal.
