Arc S – 200g Sample Roaster
$3,510.00 – $14,900.00
The Arc S is a closed barrel, modular sample roasting system with batch sizes that range from 50g-200g. Small minimum batch sizes allow labs to get as many roasts as possible on scarce offer and pss samples. The Arc S is built for precision with RTD probes measuring ET and BT, communicating through a redesigned motherboard for responsive communication with Artisan / Cropster. The native roast tracking and small drum size allows labs to re-roast samples (with accompanying roast curve data), to guarantee they are cupping a good representation of a lot. As labs see samples arrive in torrents during peak harvest, the modular nature – up to four barrels per exhaust line – of the Arc S allows for maximum roasting efficiency when handing heavy sample volumes. Because the Arc S was designed as a closed-barrel environment, roasters that are experienced in larger-format drum roasting will find that their skills translate directly, and the operation of the Arc S intuitive. The closed barrel design closely approximates a production environment allowing labs to experience coffees as their customer will and to share roast profile information for controlled calibration exercises. At scale, the Arc is a good fit for high volume import and export labs domestically and internationally. The combination of its modest price point and overbuilt feature-set makes the Arc S a nice addition for QC labs handling small pre-ships or that find value in a closed-drum design. If you’d like to try an Arc, please email us to set up an appointment at the Crop to Cup Coffee Importers Showroom, or a nearby shared roasting facility.
Arc S – Features
ROASTER TYPE: Modular sample roaster, professional, gas or electric
BARRELS: Intuitive, closed-barrel system that approximates a larger production environment. Available, in 1, 2, 3 or 4 barrel configurations, with separate heating, exhaust and cooling to achieve consistency between barrels.
CAPACITY: 50-200 grams / 0.11-0.44 pounds. Suggested roast volumes: 125 grams or 200 grams
HEAT SOURCE: Gas heat / propane (LP) or LNG at 8,000 BTUs. The majority of customers operate with LPG/propane due to much easier setup and more reliable pressure than LNG. On multiple drum units, only one propane tank is needed (gas splits to each unit).
CONTROL: This machine is designed to have all the manual controls that larger capacity commercial machines would offer. The Arc S features a variable speed drum as well as stepless control of airflow and heat.
AIRFLOW METER: Air pressure gauge for measuring airflow included standard on the Arc S. On multiple-drum units, each unit has its own airflow meter and exhaust fan. Having an airflow meter on each unit allows for users to respond and make easy adjustments in airflow and gas to achieve consistency between drums (to fairly evaluate samples side by side, matching roast environments is critical when roasting multiple samples at the same time).
TEMPERATURE PROBES: 3 temperature probes track temperatures at 100-500 millisecond sampling rate on the roaster screen or on a computer. 2 x 3mm RTD PT100 temperature probes measure exhaust/environmental temperature (ET) and bean temperature (BT). A 4mm K-type thermocouple measures incoming air temperature. Fully compatible with Artisan / Cropster – probes send data to Artisan or Cropster at a 100 millisecond (1/10 second) sampling rate, or to the roaster’s screen at a 500 millisecond (1/2 second) sampling rate.
COOLING: Separate cooling fan(s). On multiple-drum units each unit has its own cooling tray fan.
TIME RANGE: 7 – 12 minutes
VENTILATION: Via 3″ flexible venting duct, utilizing separate outlets from cooling fan and airflow fan. On multiple-drum units, each unit has its own exhaust fan. Exhaust lines all connect to to one shared final exhaust outlet (via a stainless steel connector with customized internal branches to reduce air friction between the units’ airflows). Or you can vent each one out separately without connecting them.
WARRANTY: Industry standard warranty covers parts for 1 year. Shipping on parts is covered for the first month.
WEIGHT (1 barrel): 82 lbs
ELECTRICAL: 110v (100-120v) or 220v (200-240v). On multiple drum GAS units, only one plug is needed to electrical source (additional units plug into the main unit for power). On fully electiric multiple drum units (no gas), each unit requires its own electrical outlet. Each fully electric unit (no gas) requires 10amp and 2000 watts.
FOOTPRINT: 28.6 x 10 x 28.2 in (depth x w x h)
SHIPPING WEIGHT: 127 lbs
SHIPPING DIMENSIONS: 35 x 18 x 28 in (l x w x h)
DRUM: Variable Speed (27-82 RPM), Carbon Steel (very similar to cast iron), Solid Drum, with 25w motor, 4.5 in (114mm) diameter, 3mm thickness
COOLING TRAY: 20w motor
EXHAUST FAN: 25w motor
