PEAK-P8 Automatic Coffee Roaster

Gas and Electric Heating Configurations

The PEAK-P8 is available with gas or electric heating, providing greater flexibility for different production sites. The gas version supports LPG and LNG, operates at 220 V with a rated power of 1600 W, and uses a Venturi-premixed combustion system. The required gas supply pressure is 4 kPa.

The electric version operates with a three-phase 380 V power supply and has a rated power of 18400 W with a rated current of 30 A. Its multiple-unit heating-wire system distributes electric heat across the roasting chamber to support stable convection heating.

Both configurations provide the same 3–8 kg batch range, 6–15-minute roasting cycle, and rated production capacity of 32 kg/h, allowing users to select the heating source without changing the main roasting workflow.

Double-Wall Drum and Adjustable Roasting Control

The roasting chamber uses a double-wall cast-steel drum with a double-layer, multi-piece paddle structure. The double-wall design helps create a more balanced combination of stored heat and convection heating, while the internal paddles continuously move the coffee beans throughout the roasting cycle.

Drum speed can be adjusted from 10 to 62 rpm through high-precision frequency control. This wide adjustment range allows the operator to coordinate bean movement with batch size, airflow, heat input, bean density, and roast development requirements.

Combined with the machine’s controllable hot-air system, the drum structure supports more stable heat transfer and provides the flexibility needed for different coffee origins and roasting profiles.

Intelligent Roasting and Curve Management

The PEAK-P8 is equipped with the iHB intelligent roasting system and a 13.3-inch HD display. The interface supports manual and automatic operation, allowing users to develop profiles manually or automate established roasting procedures for repeat production.

During roasting, the system displays four-way temperature data, rate of rise, air pressure, and gas pressure in real time. This information helps operators observe how heat and airflow changes affect the roasting curve and make more accurate adjustments throughout the process.

The software also provides bean-temperature prediction, estimating the future direction of the bean-temperature curve to assist with roasting decisions. USB and HDMI data output support external display connections, data management, and roasting-record applications.

Constant Air-Pressure and Independent Exhaust Control

The PEAK constant air-pressure system automatically adjusts fan speed to maintain a consistent hot-air flow rate. Stable airflow helps reduce pressure variation inside the roasting system and creates more consistent operating conditions for profile reproduction.

The hot-air system provides a discharge volume of 7.2 m³/min through a 150 mm duct. Air-pressure values are displayed directly on the roasting interface, allowing operators to observe airflow conditions and coordinate them with temperature, gas pressure, and roast development.

Hot-air exhaust and cooling use separate ducts, preventing roasting exhaust from interfering with the cooling process. This independent arrangement supports more controlled airflow during roasting and more efficient heat removal after discharge.

Rapid Cooling with Integrated Weighing

After roasting, the beans are transferred to a stirring cooling tray with a fan discharge of 30 m³/min. The strong cooling airflow rapidly removes residual heat, helping stop roast development and prepare the machine for the next batch.

The cooling system uses a 150 mm duct and is separated from the hot-air exhaust path. The cooling tray also includes an integrated weighing function, allowing operators to check roasted-bean weight directly within the production workflow.

The bean spout can be adjusted to multiple angles, making it easier to coordinate discharge with containers, conveying equipment, or the surrounding workspace.

Flexible Operation and Material Handling

The PEAK-P8 provides automatic and manual control for both the hopper lever and drum-door lever. Operators can use automatic control for standardized production or switch to manual operation during profile development, testing, or process adjustment.

A swivel-arm control desk allows the operating interface to be positioned at different angles, improving access from various working positions. The machine can also be linked with a feeding conveyor to create a more integrated loading and roasting process.

A drawer-type chaff bucket simplifies chaff collection and removal, while the adjustable bean outlet and integrated cooling tray support a more organized production workflow.

Integrated Commercial Roasting Structure

The PEAK-P8 measures 2280 × 1000 × 1850 mm and weighs 550 kg. Its integrated structure combines the roasting chamber, combustion or electric heating system, cooling tray, chaff collection unit, airflow control system, operating interface, and bean-handling components within one complete machine.

The package dimensions are 2680 × 1140 × 2080 mm, providing reference information for transportation, unloading, workshop access, and installation planning.
