Description
 
Any single vessel system with a sizable deadspace below or to the sides of the bag or basket will greatly benefit from constant stirring of that area during the mash for a few reasons:

  1. Specifically in electric heated systems, the heat source is a relatively small area that heats up quickly while the temperature probe is sufficiently far away that it never quite senses the average temp of the entire dead space if it is allowed to sit still.
  2. These systems typically have a whirlpool port for stirring (whirlpooling) the wort post boil, but can easily be leveraged for stirring to keep the temperature homogeneous in the entire dead space.
  3. The recirculation flow over the top of the mash must be carefully throttled to avoid over-pumping faster than the mash/basket/bag can flow. If not, you can fully expose the element to air and cause a scorching dry fire. That flow rate is approximately 1.5 liters per minute but it is quite difficult to accurately set a valve to deliver that slow flow with a typical powerful brewing pump.
Our solution to all these situations is to split the output of the pump to deliver the flow to both the whirlpool port as well as the upper recirculation port. Both of those flows can be fully open, fully closed or any mix you wish. Our recommendation during the mash is to open the whirlpool valve fully and then throttle the recirculation valve to deliver about 1.5 liters per minute to the recirculation. Allowing a majority of the pump's flow to bypass to the whirlpool makes it very easy to fine tune the recirculation flow as the pressure is greatly diminished.

This specific kit is designed for systems that use 1/2" NPT ports and accessories (e.g. Spike Solo NPT). It also assumes you have a pump with 1/2" NPT on the output and a threaded on valve with male QD on the output (this is the case if you have purchased the pump kit from Spike). To be clear, you will move the pump's ball valve and male QD to AFTER this tee. That valved output goes to your recirculation port over the grain. The open port of the tee goes to the whirlpool port (where you already have a valve and QD).

The kit includes:
(1) 1/2" NPT TEE (this goes between your pump output and the 3pc ball valve you already have)
(1) Premium Hex Nipple
(1) Male Quick Disconnect
(1) 3ft length of silicone tubing
(2) Female QD x 5/8 barb fittings (crimp clamped into the tubing above)This kit is everything you need to make this conversion happen. The list of parts and retail cost is shown below.






If you do not have the stock Spike pump kit and you do not already have a valve and male QD, you can add those to your cart separately:
