RIMS or Recirculating Infusion Mash System

RIMS or recirculating infusion mash system is a mash infusion system that either utilizes a pump to recirculate the fluid in the mash over a secondary heat source (outside of the mash tun) to maintain the mash temperature, or constantly recirculates the mash onto itself while direct heat is applied to the mash tun to regulate the temperature. The fluid is pumped at a rapid enough pace to keep the temperature of the mash at an equilibrium and prevents the wort from being scorched or overheated.

HERMS or Heat Exchanged Recirculating Mash System

A HERMS or heat exchanged recirculating mash system is a mash recirculation system that regulates mash temperature by pumping the wort from the mash tun through a heat exchanging tube, coil inside of the hot liquor tank, or a secondary heating tank. The wort then flows back into the mash tun to maintain the mash temp without applying direct heat to the mash tun.
