A 2 kg coffee roaster occupies a critical position in the specialty coffee equipment market. It delivers enough throughput to supply a busy single-location café or a small direct-to-consumer brand, yet stays compact enough for a commercial kitchen or modest roastery without a major facility build-out. Operators who have maxed out a 1 kg machine — or who want genuine production capacity from launch day — routinely settle on the 2 kg class as the most cost-efficient path to a sustainable roasting business.
Typical buyers at this capacity include specialty café owners adding an in-house roasting program, micro-roastery founders targeting local wholesale accounts, green bean importers running quality-control cuppings at scale, and food-and-beverage entrepreneurs testing a private-label brand before committing to larger equipment. A properly run 2 kg roaster can produce 20–30 kg of finished coffee per day on a realistic eight-hour schedule — enough to cover a café’s daily house-roast needs while leaving capacity for online or wholesale sales. For a full framework on mapping output to revenue targets, see our commercial coffee roaster capacity guide.
2 kg Roaster Output Math: What Can You Actually Produce?
Capacity ratings refer to maximum green-bean load per batch, not finished roasted weight. Green beans lose roughly 15–20% of their mass as moisture during roasting, so a 2 kg green-in batch yields approximately 1.6–1.7 kg of roasted coffee. The table below shows realistic daily output at three operating intensities based on a standard eight-hour production day.
| Scenario | Batch size (green) | Cycle time | Batches / hour | kg / day (8 h) | lbs / day |
|---|---|---|---|---|---|
| Conservative (70% duty) | 1.5 kg / 3.3 lb | ~25 min | 2.4 | ~17 kg | ~37 lb |
| Practical target (75% duty) | 1.7 kg / 3.7 lb | ~20 min | 3.0 | ~26 kg | ~57 lb |
| Efficient (80% duty) | 1.8 kg / 4.0 lb | ~18 min | 3.3 | ~32 kg | ~71 lb |
Cycle time includes the roast itself (typically 10–14 minutes), cooling (5–7 minutes on a dedicated tray), and batch turnaround. Use 25–30 kg of finished roasted coffee per day as a safe business-planning figure if you run a well-optimized schedule. A single-location café serving 200–300 covers daily rarely needs more than 5–6 kg of roasted coffee per day, which a 2 kg roaster covers in two hours — leaving the remainder of your production window for additional SKUs or wholesale fulfillment.
What to Look for in a 2 kg Coffee Roaster
Drum Construction
At 2 kg, a double-layer drum — whether cast iron or double-wall stainless steel — is the standard marker of commercial-grade equipment. A double-layer drum retains heat more evenly across the drum wall, reducing hot spots and giving you tighter batch-to-batch consistency. This matters most when you are roasting multiple back-to-back batches for wholesale customers who expect repeatable flavor profiles. Single-wall drums, more common on prosumer or lightly built machines, lose heat faster and respond less predictably to mid-roast airflow adjustments.
Burner System and Heat Control
Gas-fired drum roasters dominate the 2 kg commercial category because gas delivers rapid, responsive heat. Look for an independently adjustable burner capable of bringing a cold drum to roasting temperature (typically 180–220 °C bean probe) within 15–20 minutes. PID or analog temperature control is standard at this class; digital PID with a real-time bean-probe display is strongly preferred if you plan to develop and replicate roast profiles across batches or operators.
Airflow (Damper) Control
Variable airflow via an adjustable exhaust damper is not optional at the commercial level. Airflow governs the convective heat delivery rate, chaff evacuation efficiency, and roast development time. A fixed-airflow machine forces you to compensate entirely through gas, which dramatically limits roast profiling flexibility. Verify that the machine you are considering ships with an operator-accessible damper that can be adjusted during the roast.
Cooling Tray and Throughput
A front-mounted cooling tray with a motorized agitator arm and suction fan cuts cooling time to 4–6 minutes. This is directly tied to your batch throughput: faster cooling means faster turnaround and more batches per available hour. A cooling tray also protects roast quality by rapidly arresting the Maillard reaction the moment beans are dropped, giving you a cleaner stopping point for light and medium roast profiles.
Chaff Collection and Exhaust
A 2 kg roaster running consecutive batches generates enough chaff and smoke that a cyclone chaff collector and dedicated external exhaust duct are standard requirements, not optional accessories. Confirm that the model ships with a cyclone collector or that one is available as an add-on, and plan your exhaust duct routing before you finalize the installation location.
The Yoshan DY-2kg: Specifications and Features
Yoshan’s commercial coffee roaster lineup includes the DY-2kg as its production-entry model for operators stepping up from sample-scale equipment. Built with a double-layer drum and variable airflow damper, it is engineered for daily multi-batch operation at café and micro-roastery scale.
| Specification | DY-2kg |

| Cooling tray | Included |
| Certifications | CE, SGS, ISO 9001 |
| Warranty | 1-year whole-machine warranty |
| Indicative price | ~$3,399 |
The double-layer drum improves thermal mass and distributes heat more evenly across the bean bed compared to single-wall alternatives, which translates to more consistent roast development — particularly important when transitioning from lighter profile origins to heavier natural-process batches in the same day. Variable airflow gives you independent control over convective heat delivery, which is a meaningful advantage when dialing in origin-specific roast profiles or working with different crop years of the same green coffee.
Yoshan machines ship worldwide from the factory in China and carry CE, SGS, and ISO 9001 certifications. The 1-year whole-machine warranty covers parts and factory technical support.

Installation and Utility Requirements
Gas Supply
The DY-2kg requires either LPG (propane) or natural gas. Specify your local gas type when ordering, as the burner orifice is set at the factory. A licensed gas technician must complete the final connection in most jurisdictions. Plan for a dedicated manual shutoff valve and a flexible stainless gas line at the machine location.
Exhaust Ventilation
At 2 kg per batch running three or more batches per hour, a direct exhaust duct to an exterior wall or rooftop is required. The minimum recommended duct diameter is 150 mm (6 inches); shorter duct runs perform best. If your local authority requires smoke abatement, Yoshan offers a static smoke filter and afterburner as auxiliary equipment — confirm compatibility and availability when requesting your quote.
Electrical
The DY-2kg uses a single-phase 220 V supply for the control panel, drum drive motor, and cooling tray fan motor. This is a standard commercial outlet type in most markets. Confirm your local nominal voltage with the factory if you are sourcing from a market outside the standard 220 V range.
Footprint and Clearances
A 2 kg roaster requires a floor footprint of roughly 80–100 cm × 60–70 cm, plus clearance on all sides for heat dissipation, exhaust collar access, and operator movement. Allow at least 60 cm behind the machine for the exhaust connection and 120 cm in front for the cooling tray drop zone and bag-off area. Verify ceiling height accommodates the exhaust stack collar before finalizing placement.

Frequently Asked Questions
How much coffee can I roast per day with a 2 kg coffee roaster?
On a practical eight-hour operating schedule at 75% duty cycle, a 2 kg roaster producing approximately 1.7 kg per batch at three batches per hour yields roughly 25–30 kg of finished roasted coffee per day. Conservative operation at two batches per hour delivers 15–18 kg/day; an efficient production schedule can approach 30–35 kg/day. Use 25 kg/day as your baseline planning figure.
Is a 2 kg roaster large enough for a café?
Yes, for most single-location specialty cafés. A busy espresso bar serving 200–300 covers per day typically uses 3–6 kg of roasted coffee daily. A 2 kg roaster can cover that demand in two to three hours, leaving remaining capacity for additional SKUs, bag retail, or a small number of wholesale accounts. If you plan to supply multiple locations from the same machine from day one, consider starting with a 3–6 kg model.
What gas type does the Yoshan DY-2kg use?
The DY-2kg is available configured for either LPG (liquefied petroleum gas / propane) or natural gas. You must specify your local gas type when requesting a quote, as the burner orifice is set at the factory during build. Switching gas types in the field requires a conversion kit and a licensed technician.
What ventilation is required for a 2 kg coffee roaster?
A minimum 150 mm (6-inch) direct exhaust duct to an exterior wall or rooftop is standard. Duct runs under 5 meters perform best; longer runs may require an inline booster fan. In jurisdictions with air quality regulations, a smoke abatement device — static filter or afterburner — may be required. Yoshan offers both as auxiliary equipment; ask about compatibility when ordering.
How does the DY-2kg compare to a 1 kg roaster?
A 1 kg machine is well suited to sample roasting, R&D, and very small retail production under 10 kg per day. The DY-2kg doubles the batch size, roughly doubles daily throughput, and adds the heavier double-layer drum and variable airflow damper that professional roasters need for consistent quality across multiple consecutive batches. The price step from 1 kg to 2 kg is moderate relative to the production capacity gained.
What is the lead time and warranty for the DY-2kg?
Lead time varies by order volume and factory schedule — typically 15–30 business days for standard configurations. The DY-2kg carries Yoshan’s 1-year whole-machine warranty covering parts and factory technical support. Contact the factory directly for current lead time when you request your quote.
