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.
Please Note: ALL HARDWARE is in one zip-lock bag taped to the Hopper Support Mast

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.

Thermometer
Your thermometer will be placed on the Thermometer
bracket located on the left side of the roaster.
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 on the bracket as shown in the picture below. The bottom of the thermometer
should be even with the bottom of the thermometer bracket.

INSTALLING EXHAUST BLOWER
1. You will need to purchase the proper electrical plug for your plug in and attach it to your blower
wire.
2. Place the 6 X 4 X 4 Wye on the intake side of the blower. Position it to best suit your roaster
exhaust hose positions. 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. While both 4’’ and 5’’
duct is acceptable for exhaust duct size, we recommend using rigid ducting on the discharge side.
Be sure to tape the duct seams on the room interior side of the duct system as discharge gas is
under pressure.
4. For exhaust duct runs of 20 feet and longer we recommend using 4’’ rigid duct to increase the air
velocity to the discharge point. Do not use flex ducting for runs over 6 feet.
5. VERY IMPORTANT! All of the duct joints and seams on the discharge side 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.

INSTALLING EXHAUST BLOWER CONTINUED
NOTE: Some installations may require longer runs to access a through wall fitting to the outside
atmosphere. For longer runs please consult the outline below about lengths and deductions for
elbows.
To reduce noise in the roasting area, install the exhaust blower under an insulated enclosure or on
the other side of a wall. The exhaust blower motor is air cooled so make sure to not seal it
completely without an intake air source.
Recommended Duct Length with Elbows
 4’’ exhaust duct runs should not exceed 80 feet. Deduct 5 feet for every 90-degree elbow in the run.
 5’’ exhaust duct runs should not exceed 65 feet. Deduct 5 feet for every 90-degree elbow in the run.
 6’’ exhaust duct runs should not exceed 50 feet. Deduct 5 feet for every 90-degree elbow in the run.

Ventilation Installation
The Valenta 7 roaster must be exhausted in accordance with the manufacturer’s instructions as documented
in the prior section of this manual. The roaster exhaust system must be independent of all other systems.
Exhaust Penetrations
Any wall or ceiling penetration of ducts that transfer roaster exhaust must meet the International Building
Code fire-resistance rating and cannot be located within any fire-blocking* and/or draft-stopping* areas.
Unless such duct work is constructed of galvanized steel or aluminum of a thickness specified in Section
603.3 of the International Building Code and the fire-resistance rating is maintained.
*Fire-blocking: Prevents movement of flame, smoke, gases through concealed spaces. Primarily
addresses vertical movement.
*Draft-stopping: Prevents movement of smoke and gases through concealed spaces. Primarily
addresses horizontal movement.
Cleanout
All ducting from the blower discharge to the outlet terminal must have a means for cleanout. Exhaust duct
cleaning is required for all coffee roasting installations. Inspect exhaust tubing frequently. Clean or replace
if excessive build up is present.
Maximum Run Length
Maximum 5” diameter exhaust run shall not exceed 50’ (feet) from the exhaust blower to the outlet
terminal. For every 45° bend included in the exhaust duct path, 2 ½’ (feet) must be deducted from the
maximum of 50’ duct work. For 90° bend included in the exhaust duct path, 5’ must be deducted from the
maximum of 50’ duct work.
Example: There are two (2) 45° bends included in the exhaust duct path. The total maximum run
length for a 5” exhaust duct is now 45’ (feet).
Blower Intake to Roaster Ducting
Flexible ducting is acceptable from the roaster/chaff canister to the plenum. Flex ducting must be all metal.
DO NOT USE plastic dryer ducting or aluminum flex duct with plastic liner.
Blower Discharge Ducting
USE ONLY RIGID ducting from the blower discharge to the outlet terminal.
Exhaust Gas Temperature
The exhaust gas temperature must not exceed 170° Fahrenheit (76.6° Celsius).
