The kettle/whirlpool tank combines the boiling and whirlpool functions of wort into one tank, which is a great way to save space and budget.
After boiling, the wort is pumped out of the kettle/whirlpool tank and then returned to the kettle/whirlpool tank through a tangential inlet. It takes 5 minutes to recover the wort with the pump, and then the wort is allowed to sit in the tank for 30-45 minutes to concentrate the residue in the bottom of the cone and then drained out.
For small-scale kettle/whirlpool tanks, there is no mixing system in the tank, as the boiling wort can be mixed manually. But for some brewers who are looking for top quality and attention to all details, they always prefer to install a blending system with VFD control to mix the wort evenly.
But for a combination kettle/whirlpool tank, won’t the mixing system have a problem with the whirlpool process? Won’t the blades affect it?
More or less, the blades can have a negative impact on the whirlpool process. Therefore, we have designed a new mixing system, which means that the blades can move along the central axis. During the boiling process, the blades mix the wort at the bottom of the jar. After the mixing is finished, the blades can be lifted by a hook and hung on the sidewalk. Because the blades are placed on top of the wort, they do not interfere with the whirlpool.
