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.

Thermometer
Your thermometer will be placed on the Thermometer
bracket located on the left side of the roaster (see
next page for instructions).
The Digi-Sense Thermometer is very easy to operate
(pictured). The large display makes the bean temperature
reading easy to see. There are only a few basic operating
functions.
1. The meter has an auto off function and will power
down after 30 minutes with no key operation. To
disable the auto power off mode, press and hold
the “H” and “Power” keys at the same time. The
clock dial in the upper left corner of the screen will
disappear and the auto off will be disabled.
2. When the battery voltage is under the proper
operation requirements the low battery symbol will show on the LCD screen and the battery will
need to be replaced.
The thermometer comes to you with the battery and thermocouple probe installed and tested. Velcro has
been applied to the back of the thermometer. To install it on the thermometer bracket, remove the plastic
from the Velcro and install it on the bracket as shown in the pictures on the next page. The bottom of the
thermometer should be even with the bottom of the thermometer bracket.

INSTALLING THE POWER DISTRIBUTION BLOCK AND TUBE
1. Remove the panel that covers the electrical assembly on the left side of the roaster as shown below.
2. Take off the front plate on the power distribution box in order to access the inside of the box. Use
two of the 8/32 screws provided to secure the box to the back of the roaster as shown below. You
can leave the front plate off for now as it will need to be off for your electrician to run the wires.
3. Use the two remaining 8/32 screws to secure the tube to the roaster from the inside, below the
electrical assembly as shown below. Please note, the tube should secure to the hole on the box, the
screws will not fit otherwise.
Note: We recommend having an electrician wire the roaster for you based on your building’s
electrical setup.

ASSEMBLING THE BEAN COOLER
1. Remove the Bean Cooler from the pallet and

the Bean Cooler Tray Handles and hardware
kit.

he
handle into the bolt and secure it with the
lock washer and nut.
3. Do this three more times, two for each
handle and four total.
4. Take the tray off and turn the bean cooler
upside down.
5. Take the Bean Cooler Exhaust Fitting and
push it through the hole on the back of the
Bean Cooler with the longer side going in
first.
6. The fitting should fit around the 90-degree
duct inside the bean cooler. Once in place,
secure it with the provided 8/32 keps nuts.
7. Once the fitting is secure, use the provided
high temp tape to cover the seem between
the fitting and the duct.

INSTALLING EXHAUST BLOWER
1. You will need to purchase the proper 20-amp electrical plug that matches the outlet you are
plugging the blower into and attach it to your blower wire.
2. Place the 6 X 6 X 6 Wye on the intake side of the blower. Position it as shown in the picture
below. Secure the wye with the self-taping screw provided you (attached to the wye in a plastic
bag).
3. The exhaust blower comes with a 5-inch flange on the top discharge outlet. We recommend using
5-inch rigid ducting on the discharge side. Be sure to tape the duct seams on the room interior side
of the duct system as discharge smoke is under pressure.
4. VERY IMPORTANT! All of the duct joints and seams on the discharge and intake sides of the
blower must be sealed with high temperature tape. The discharge exhaust ducts are under
pressure and will leak smoke into the roasting area if not sealed.

atmosphere. Use the diagram below to see how the ducting setup should look and then adjust the
run from the blower to the outside as needed. The parts in RED are duct fittings that are provided by
Coffee Crafters. All other ducting parts must be provided by the customer. USE ONLY RIGID DUCTING
