Diedrich's 24 kilo Industrial Workhorse!

Made in USA

This is Diedrich's classic IR series 24 kilo roaster. Perfect for the step up from your 12 kilo batch machine. This beautiful 2006 model roaster is in great condition and has been meticulously maintained throughout its life. Purchased new/original owner. It also comes with a Diedrich Catalytic Oxidizer (DCO) (see pictures and video).


Running next to 2 other Diedrich IR-12s, this beauty was the owner's primary production roaster from 2006 until May 2021. 

Currently running on Natural Gas, it only has a few aesthetic blemishes. Other than than that no issues. Electrical is 110v!

Also has a owner installed bean temp probe and a data port output for Cropster or Artisan.

NOTE: The flame Igniter was being temperamental so was replaced with new and there was a set screw that backed off the rear bearing about 4 years ago. Hanger carrier base was modified and set screw relocated to fresh shaft for connection. Completely resolved. Been running 4 years since with no problems. Inquire for more info.

Also includes Selkirk Metalbestos double-walled stainless steel negative pressure ducting. About 8' from top of afterburner to ceiling. The footprint including the oxidizer is about 12' long by 4' wide. Height of afterburner is 87.5". Stainless steel base pieces that were fabricated can be include in the purchase.

Chaff collection on these IR-24s is internal, so no external chaff collector included.

Located up in the northeast USA, this machine purrs like a kitten, roasting every batch with consistency and repeatability. The Diedrich IR series machines are known for ensuring a perfect roast, batch after batch.

Owner is selling due to a new facility relocation with a new Loring 70k roaster. No longer use the IR24 and have no need for it.


Priced at an excellent value. Grab this deal NOW!

This is a prime opportunity for a roastery looking to move up from 12 kilo shop roasting to the next level of industrial output.
