A direct fired MLT with recirculation so in essence it's a RIMS I suppose. I prefer it for it's simplicity. I cannot use my sparge arm, it's a rotating arm that will not, cannot, absolutely will not take fine particles of grain and ****e in the tubing. I'll figure it out eventually. I'd rub it in but the peoples on here are so awesome, thankyou for all your advice, just come to Florida panhandle and drink and stay for free, cheers!
