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 7 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.

Assembly and Installation
Assembly Introduction
Your Valenta 7 roaster comes mostly assembled. The following instructions will help you complete the
assembly process correctly.
Before you start the assembly process you must select a suitable location for the Roaster and Blower
System. The Blower System can be installed in any location within 10 feet of the Roaster including on the
other side of a wall. You may prefer this installation method if the noise is an issue. The customer must
supply the 5” rigid ducting for outside venting. If you decide to put the Blower System in a different
location additional vent pipe and fittings will be required. Make sure to check with local codes for venting
requirements as noted in the ventilation installation section of this manual. When correctly installed, the
exhaust gas temperature will not exceed 170° Fahrenheit.
The Roaster must be positioned on a flat smooth surface, do not install on carpet. Make sure the Roaster
has at least a 6-inch gap between the back vent pipes and the wall.
Hardware Packages
Your Valenta 7 roaster comes with all the fittings and hardware needed to install the chaff collector, roaster,
bean cooler and exhaust blower. Not included is the electrical cord or ducting on the discharge side of the
exhaust blower. A complete list of included hardware and fittings and listed below.

Taking the Roaster Off of the Pallet
Step 1: Unscrew the Shipping Brackets on the front and Stabilizing Feet on the back of the roaster. Set the Stabilizing
Feet aside, you will be putting them back on later. You can throw out the Shipping Brackets, they are no longer
needed.
Step 2: Take the roaster off of the pallet and place it in your roasting area.
Step 3: Screw the Stabilizing Feet back into the back of the roaster as pictured below. Please note: these feet are
very strong and can dent the roaster if you move it while the feet are attached so it is a good idea to wait to put the
feet back on until after the roaster is in the position you want to leave it in.
