Professional Coffee Bean Roaster
Fig. 1
Roaster Base contains the control panel, heating elements, Catalytic Converter
and mounting base for roasting chamber. A two-speed fan directs the heated air
through the green coffee beans in the ‘roast’ cycle and blows cool air through the
roasted beans, during the ‘cooling’ cycle, to stop the roasting process.
Roaster Chamber holds up to 5 oz. of green coffee beans and features a unique
auger drive mechanism that mixes the coffee beans so they roast evenly.
Chaff Cup collects the ‘fl uffy’ chaff generated when roasting coffee beans.
Screen / Front Seal: The stainless steel Screen fi ts inside the Front Seal and
prevents fi ne chaff particles from entering the Catalytic Converter. The Front
Seal keeps smoke and odor inside the machine.
Rear Seal prevents smoke and odor from leaking out at the Catalytic Converter.
Cover directs the smoke and odor from the Roasting Chamber to the Catalytic
Converter where it is virtually eliminated. It is conveniently hinged to the
Roaster Base and activates the Safety Cutoff Switch when the Cover is latched.
Safety Cutoff Switch allows the roaster to operate only when the Cover is
properly latched. It will turn the roaster off if the Cover is accidentally opened
during a roast cycle.
A patented Catalytic Converter removes the smoke and most of the odor
associated with roasting coffee. No other home coffee roaster has this feature.
Control Panel
Your NESCO® Professional Coffee Bean Roaster features an easy to use Control
Panel that includes fi ve large keypads, large digital display and two indicator
Fig. 2
NOTE: The screen must be cleaned between EVERY use to ensure proper and
safe operation of your roaster (see Caring For Your Roaster).
CAUTION: Failure to clean the fi lter screen or operating the appliance
without proper installation of the fi lter screen may cause your roaster to
malfunction. Roaster issues caused by leaving out the screen will NOT be
covered by the warranty.
IMPORTANT: Make sure the Chaff Cup is inserted in the glass cylinder of
Roasting Chamber before the Front Seal / Screen is installed. Remember, all
metal surfaces become EXTREMELY HOT during the roasting process and
should never be handled or touched during or directly following a roasting cycle.
7CR-1000 Series Coffee Bean Roaster
Before You Begin
Before using your NESCO® Professional Coffee Bean Roaster the fi rst time:
Unpack your new coffee bean roaster completely. Remove all packing
materials and make sure all parts are included. (Fig 1).
Wash Cover, Chaff Cup and Roasting Chamber in hot soapy water to
eliminate any residue from the packing that will affect the fl avor of your
rst roast. Rinse in clean water and dry thoroughly. All removable parts
Make sure all parts are completely dry before reassembling your roaster.
NOTE: Set Cover on end to allow excess water to drain.
Select your favorite green coffee beans and get ready to roast your fi rst
Operating Instructions
Place Roasting Chamber on Drive Shaft and lower it onto heat shield.
Align the Guide Slots with Locator Pins, and Roasting Chamber will drop
into position on Heat Shield (Fig. 3).
Fill Roasting Chamber up to either “FILL LINE” or “DARK ROAST”
line with your choice of green coffee beans. NOTE: Do not over fi ll the
Roasting Chamber, as this could damage the roaster.
Insert Chaff Cup into top of Roasting Chamber.
Slide the Screen / Front Seal on top of Roaster Chamber and Chaff Cup,
making sure the ribbed-end of seal fi ts over end of the glass cylinder.
Make sure Rear Seal fi ts securely over metal rim of larger opening in Cover
(Fig. 4).
Align the metal hinge pin of Cover with the matching hole in the Roaster
Body and slide together until the pin is fully seated.
Gently press Cover down until it latches in place. NOTE: If the cover is
not securely latched, the Safety Cutoff Switch will not allow the roaster to
Plug roaster into a standard 120-volt outlet. The display will show 20
minutes the fi rst time your roaster is used. This is a default setting and
will produce a ‘light’ roast. We don’t recommend roasting less than 20
minutes. We suggest a roast time of 25 minutes minimum as a starting point.
Experiment with roasting times and have fun!
Adjust roast time using the “UP” arrow (on Control Panel) to add minutes
or “DOWN” arrow to subtract minutes from the roast cycle. The longer
roast time, the darker the roasted beans will be.
Note: The maximum roast time is 30 minutes. However, during a roasting cycle, you may add
up to 5 additional roasting minutes by pressing the UP Arrow while the red light is ‘on’ and the
remaining roast time is between 6 and 24 minutes. The roaster will not allow you to add more
than 5 minutes to a roast cycle, so the maximum allowable roasting time is 35 minutes. Once
the 5-minute ‘cooling’ cycle has started and the green light turns ‘on’, you can no longer add
more roasting time.
Press the RECALL button to display the previous ‘roast time’ used when
the START button was pressed. Your roaster stores this number even if the
roaster is unplugged between roast cycles. This feature helps you roast
coffee beans more consistently.
NOTE: The RECALL button will not remember additional minutes added
after the START button is pressed.
9CR-1000 Series Coffee Bean Roaster
After you select the time for the roasting cycle, press the START button.
The auger will begin to turn the coffee beans and the fan will start.
The red light will glow, indicating the heating element is turned ‘ON’
and the roasting cycle started.
CAUTION: If the auger does not begin rotating after the START button is
pressed, a small coffee bean may be trapped under the auger inside the Roast
the roaster. Allow the roaster to cool if it is hot. Open the Cover and empty
the beans from the Roasting Chamber, making sure none are under the auger.
Rotate the auger by hand to make sure it is free to turn. Install the Roasting
Chamber with the Heat Shield and lower chamber in place. Reload the beans
and start the roast cycle again.
Note: If you roast consecutive batches of coffee beans, they may roast faster after the fi rst cycle,
because the roaster may still be hot. Adjust roast time settings accordingly.
Roasting Guidelines
Light Roast 20 - 22 minutes
Medium Roast 23 - 26 minutes
Dark Roast 27 - 30+ minutes
Note: Roast times may vary due to ambient room temperature, power/voltage, bean
variety or amounts used in each batch. Adjust time settings accordingly.
As the roasting cycle continues, you will notice the beans increase in size
and gradually change from a pale green to a chocolate brown color. You
also notice the pleasant aroma of the beans as they begin to roast.
Five minutes before the end of the roast cycle, the ‘cooling’ cycle will
automatically start and begin blowing cool air over the roasted beans. The
red light will turn ‘OFF’, the green light will glow and the fan switches to
a higher (faster) speed.Note: Pressing the COOL button at any time during
a roasting cycle will stop the roasting and begin the 5 minute ‘cooling’
When your roaster has completed the roasting/cooling cycle, the appliance
will turn itself off automatically. Note: We recommend you let the appliance
cool down for 10 minutes before removing the freshly roasted coffee beans.
CAUTION: Metal parts of your roaster WILL STILL BE VERY HOT.
Use caution when handling this appliance.
Unplug the roaster from the outlet.
After the roaster has cooled for 10 minutes, open the roaster Cover by
pulling the plastic tab towards you while lifting up. CAUTION: Please use
caution when opening or removing Cover, as all metal parts may still be
hot after the roasting cycle.
Remove Screen/Front Seal and brush chaff particles from Screen into the
trash. Slowly remove Chaff Cup and discard chaff into the trash.
Grasp the plastic handle of the Roasting Chamber and remove from Roaster.
CAUTION: Do not touch glass or metal base of Roasting Chamber as these
parts may still be hot after the roasting cycle.
Pour the fresh-roasted beans into an airtight container or coffee grinder.
Allow the roasted beans to ‘rest’ (see p. 12) for a few hours before grinding.
Grind your fresh roasted beans in a blade or burr grinder.
Brew and enjoy the best cup of coffee you’ve ever tasted!
Caring for Your Roaster
Your coffee bean roaster must be cleaned after every use. This will ensure
the safe operation of the appliance, longevity and assure optimal roasting
results. WARNING: It is very important that the screen be in place before
you start the roaster. If the screen is not in place it will cause your roaster to
malfunction. Roaster issues caused by leaving out the screen will NOT be
covered by the warranty.
Make sure the roaster has cooled before removing parts.
Empty the Chaff Cup in the trash. Brush or rinse the chaff fl akes off the
Chaff Cup and Screen/ Front Seal. To facilitate cleaning, the Screen can be
easily removed by stretching back the top ‘lip’ of the rubber seal and pulling
it out.
Wash Chaff Cup, Screen/Front Seal, Roasting Chamber and Cover with
warm soapy water and rinse. Set parts aside to drain and let them air dry
thoroughly before re-assembling roaster. NOTE: The Cover, Roasting
Chamber, Screen/Front Seal and Rear Seal are all dishwasher safe.
When dried, insert Screen into groove provided at the top of the Front Seal.
CAUTION: Not cleaning these parts or operating the appliance without proper installation
will shorten the life expectancy of the roaster and can create a condition where the roaster may
overheat and malfunction. Make sure all washable components are completely dry before using.
Set Cover on end, after washing, to allow excess water to drain out.
Wipe Roaster Body with a damp cloth or sponge and set aside to dry. DO
11CR-1000 Series Coffee Bean Roaster
Examine the slots surrounding the ‘Drive Shaft’ (Fig. 3) and remove any
debris with a damp towel or small brush. This surface must be free of debris
before beginning the next roast cycle.
The screen of the Screen/Front Seal is a very fi ne mesh stainless steel and
requires special attention after every roast cycle. Fine particles of chaff
lodge in the fi ne screen of the fi lter. Remove particles of chaff with a brush
and running water. If necessary, the screen can be separated from the rubber
seal for easier cleaning.
NOTE: A standard oven cleaner may be used to remove heavy build up of
coffee oil residue from the screen that may accumulate after several months of
steady use. Use caution when using oven cleaners. READ DIRECTIONS ON
To remove stains on inside of Cover, pour equal amounts of water and household
ammonia into the opening of Cover and let stand for several minutes. Wash
parts normally, then rinse and dry thoroughly.
It may be helpful to record the results of ‘roasts’ for future reference. This
will help you learn about the many and varied coffee types, fl avors, blends
and roast colors.
Have fun with your NESCO® Professional Coffee Bean Roaster
and enjoy the experience!
Handling and Storage of Roasted Coffee Beans
Since the primary reason for roasting coffee at home is to experience the aroma
of truly fresh coffee, you need to handle and store your freshly roasted coffee
beans with care. Green coffee beans keep very well, but after roasting begin a
slow decline and lose their freshness and fl avor rapidly.
Coffee beans reach their peak fl avor a few hours to a day after roasting. Two
days after roasting, a good part of the aroma starts to deteriorate due the affect of
the oxygen in the air (staling). After one week the taste is compromised, and in
two weeks the aroma has virtually vanished and the taste has lost its distinctive
Here are some steps to take to preserve and maximize the fragrance of your
home-roasted coffee:
Roast small quantities of coffee more often.
Allow freshly roasted beans to rest for a day, uncovered. Then transfer them
to a suitable, air-tight container and store in a cool, dry place, away from
direct sunlight. Caution: Do not fi ll a tight-sealing canister or jar more than
halfway with just-roasted coffee beans that have not been rested for a day or
so. Freshly roasted beans generate gases that will exert considerable pressure
on the walls and lid of the fi lled, tightly sealed container.
Allow roasted coffee beans to ‘rest’ for a few hours to a day before grinding.
This will assure peak fl avor and aroma.
Resist the urge to refrigerate roasted beans. Don’t store coffee in a refrigerator;
it is damp inside and dampness compromises the fl avor and aroma.
Grind your coffee immediately before brewing. The purpose of grinding
coffee is to break open the coffee bean and make the fl avor oils available
to hot water and then to our palates. Unfortunately, breaking open the bean
also exposes fl avor oils to oxygen or “staling.” Grinding should be done
only moments before brewing to maximize the fl avor and aroma.
Freeze coffee only when you have an oversupply of roasted coffee beans you
can’t consume within a week. Put the beans in a ‘zip lock’ freezer bag and
squeeze as much air out as possible before sealing. If you own a vacuum
sealing machine, this is an excellent way to preserve excess roasted beans in
bags provided or in plastic storage containers supplied by the manufacturer.
Drink your coffee immediately after brewing. It does little good to roast,
grind and brew a superb fresh cup of coffee, only to let it stand in the pot
on a hot plate where the aroma and fl avor evaporate away in the air. If you
can’t drink the freshly brewed coffee, transfer it to a pre-heated, insulated
carafe, which will preserve the taste and aroma for later consumption.
Problem Cause and Solution
Digital display is blank. Roaster not plugged in. Plug into wall outlet.
Unit will not turn on. The Safety Cutoff Switch will turn off
power to the roaster if the cover is open or
not properly closed. Make sure the Roasting
Chamber is correctly seated on the Roaster
Base and the Cover properly aligned and
latch closed.
The roasting times are not
The household voltage changing - this
changes roast characteristics.
Different varieties of green coffee beans
require different roasting times.
Similar green coffee beans from other countries
contain different amounts of moisture and
require different roasting times.
Decaffeinated beans take less time to roast
than regular beans. Trial and error are the rule
of thumb when roasting coffee beans. It may
be helpful to keep notes about roasting times
for specifi c types of coffee beans.

This condition is normal. The roaster
automatically shifts to a 5-minute cool-down
period at the end of each roasting cycle.
Roasted coffee beans are
not dark enough after going
through the maximum 30-
minute roasting cycle.
Roasting time is too short. Add extra minutes
to roast time after roasting cycle has started
and before the cooling cycle has started.

to the roast cycle. Up to 5 extra minutes can
be added.
For darker roasts use less than the

Screen/Front Seal is not installed correctly,
damaged or missing. Replace or install seal
correctly onto top of Roasting Chamber.
Make sure Screen is inserted into groove of
Front Seal.
Auger turns but beans are
not circulating.
Roasting Chamber is very dirty and needs
to be cleaned. See ‘Caring for your Roaster’
section. The oily residue on the glass prevents
the beans from circulating when the auger
is turning.
Roasting chamber may be wet on the inside.
The water droplets create a drag on the beans
preventing them from circulating. Dry the
Roasting Chamber thoroughly before adding
green coffee beans.

cooling. Only two buttons are active while the
roaster is running. These are the ‘UP’ arrow
button (increases roasting time) and COOL
You have already added 5 extra minutes,
so the ‘UP’ and ‘DOWN’ arrows will not
function. Only the COOL button functions at

This may be normal. Different varieties
of beans may roast darker than others.
Try grinding some and brew a pot of coffee.
They may taste better than they look.
Roasting time is too long. Decrease roasting
time (press ‘DOWN’ arrow).
Make sure you’ve roasted the recommended
amount of beans per load. Fill Roasting
Chamber up to the FILL LINE (5 oz.).
I want to stop the roasting
process when the beans
change color.
If you are watching the roast cycle and the
color of the beans is correct, press the COOL
button to stop the roasting cycle. The roasting
stage will stop and cooling stage will begin
