Introduction
Introduction
In this manual, you will find everything needed to start roasting coffee. Included in this copy is a description
of your warranty/guarantee, detailed information on installation and assembly, roasting instructions,
additional information on green beans, and a troubleshooting guide.
About Us
While living in Thailand and unable to find fresh roasted coffee, Ken Lathrop, developer of Coffee Crafter’s
Valenta 15 coffee roaster, conceived of a concept to design and build a reliable, affordable machine
capable of roasting five pounds or more of coffee beans in less than ten minutes.
“My goal was to enable new roasters – to help them roast their own beans and have fun doing it”, says
Lathrop. “My focus was to design and build a roaster that could be easy for anyone to learn and use, a
roaster that could roast five pounds or more per roast batch and was easily installed and affordable for
anyone. From the response we have received from customers and at coffee shows, I think we succeeded.”
Coffee Crafters designed and began selling its Artisan V fluid bed coffee roaster in August 2013. “We built
the Artisan roaster specifically to serve small roasters or those new to the industry”, says Lathrop. “The
installation is similar to your home clothes dryer – very simple and straightforward. After installation we
find that our customers are up to speed and roasting typically within 30 minutes.”
Our Mission
To become the best and largest supplier of high-quality affordable coffee “micro-roasting” equipment in
the world.
“Micro-Roasting” defined:
1. Hands on craft roasted coffee
2. Roasting 100 lbs. or less per day
3. Supply “fresh” coffee to customers immediately after roasting at its peak of freshness
Our Vision
We will maintain an uncompromising commitment to our “micro-roasting” customers by:
 Serving our customers the way we would like to be taken care of.
 Providing our customers with equipment, supplies and information to satisfy all of their micro-
roasting needs.
 Supplying high quality products engineered and manufactured in the USA.
 Delivering affordable equipment factory direct.
