EQUIPMENT
The Basic 1000 is part of LEOGAP's drum roaster technology with an attractive cost-benefit and performance. It has a robust construction, a double-layered roasting drum and an ecological internal furnace powered by gas or diesel oil and a standard afterburner for exhaust air treatment.
PROCESS
The roasting process is divided into stages consisting of preheating and the roasting drum loading, the roasting and flavoring process, and then, the roasted coffee cooling process. The Basic 1000 has air flow control. It also features with the temperature control for the surplus gases coming from the recirculation system. The roasting process is carried out by the roasting curves that can be previous programmed using the Roasting Profile software.
Benefits for your coffee
The Basic roasters show their strengths with roasting times between 08 and 20 minutes. With its dynamic system due to its drying/ roasting drum, it is possible to achieve the desired roasting profile. The Basic 1000 offers these and many other benefits:
- Adjustable roasting curve to meet production and quality requirements
- Gourmet, espresso, and instant coffee, including high and low quality coffee
- Roasting drum with an excellent heat transfer by convection and mechanical movement that produces a uniform appearance and homogeneous roasted coffee
- Aromatization process with pressurized water injection with a programmed quantity
- High efficiency cooler that maintains the beans integrity while cooling with high efficiency

CONTROLThe Basic Roasters are equipped with a distributed control system and the roasting curve is programmed using the Profile Roasting software. In this context, high-quality hardware and software guarantee maximum production reliability and safety. Customers can choose from a variety of PLC solutions and visualization concepts according to their individual demands.
- Roasting profile with parameterization of up to 10 nominal points, allowing the roasting time adjustment, temperature control, air flow and water injection
- Clear and detailed visualization of the evolution of the roasting curve
- User-defined recipe management
- Data relevant memorization to the product and the process
- Solutions for collecting and storing information in Elipse Scada database, exporting data to excel and printing reports for each roast, such as roasting time, furnace temperature, inlet and outlet weight, among others
- Automatic control system of the operation via LEOGAP´s exclusive monitoring and management system
- PLC system with network frequency drivers
- Operation history and alarm listing functions with a friendly-user interface
- The Roaster can be controlled either remotely, via the control room, or locally.
- Temperature and monitoring control, airflow, water injection and drivers by means of thermocouples, sensors and inverters
- The roaster control system safely controls, by means of signals return, alarm signals and Interlock logic,the roasting process finalization with the maximum risk reduction in emergencies
ENVIRONMENT AND COST-EFFECTIVENESSLEOGAP Roasters recirculate the liberated gases in the roasting process and use their thermal energy to create an environment-ecological. For the Basic 1000, the roasting gases recirculation is used to reduce the energy consumption and the release of harmful substances, attending to the environmental requirements. For the roaster the following configurations are highlighted:
- Reduced energy and fuel consumption due to heat recirculation
- Reduction in emission values and adherence to local limits
- Minimun heat loss due to an excellent isolation system
- Chaff extraction from the roasting and drying process
SafetyLEOGAP´s safety technology goes far beyond the standard requirements. We offer high-quality components that guarantee the maximum safety process:
- Automatic safety supervision system, with simple and safe operations even in dark roasts with low-quality green coffee
- Anti-condensation system in order to prevent the formation of crust (manual flap to adjust the air flow and temperature conditions) and to reduce maintenance
- The roaster critical temperature points are constantly monitored
- Alarm system and parameterized setpoints for operational safety
- Automatic water in case of emergency
