EQUIPMENT
The LEOGAP Turbo is a roaster of the latest generation. It is automatic and offers high reliability, being designed with the newest technology and manufactured with materials of internationally proven quality. With a tangential roasting system, the roaster consists of drying and roasting chambers that allow high performance and low energy consumption.
PROCESS
The coffee is roasted in two fixed chambers with a mechanical stirrer that moves the green coffee during the roasting process. The chambers operate simultaneously and alternately by drying and roasting the coffee at the same time and a continuous action: while one system is drying, the other one is roasting. It uses high flow with controlled temperature for extremely fast roasting. The roasting curve is programmed using the Profile Roasting software. The entire operation is carried out using the tangential roasting process.
BENEFITS FOR YOUR COFFEE
Turbo roasters show their strengths at roasting times between 4 and 8 minutes. With a dynamic system in the roasting chambers, it is possible to achieve the desired coffee profile. With a nominal production capacity of 4000 kg / h, the Turbo 4000 tangential roaster is perfect for high-level production with flexible batch sizes. It stands out thanks to its sophisticated technology, and numerous standard, and upgradeable technical resources. The Turbo 4000 tangential roaster is designed to produce and operate 24 hours a day, 7 days a week.
The Turbo 4000 offers these and many other benefits:
- Adjustable roasting curve to meet production and quality expectations
- Gourmet, espresso, instant coffee roasting, including high and low low-quality products
- Tangential roasting with excellent heat transfer by convection and mechanical movement allowing uniform appearance and homogeneous roasting of the beans
- The rotary blade mechanism inside the roaster / dry chambers is developed for optimal and smooth mixing of coffee beans
- Aromatization process with pressurized water injection with programmed quantity
- Chambers for cooling the beans using ambient air, maintaining the main characteristics of the coffee

- User-defined recipe management
- Memorization of relevant data to the product and the process
- Solutions for collecting and storing information in a Microsoft SQL Server Express database, exporting data to excel, and printing reports for each roasting, such as roasting time, furnace temperature, inlet and outlet weight, among others
- The 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 user-friendly interface
- The roaster can be controlled either remotely, via the control room, or locally, via the HMI (Human Machine Interface) installed on the panel next to the roaster
- Monitoring and control of temperature, airflow, water injection, and drives by means of thermocouples, sensors, and inverters
- The roaster control system safely controls, by means of return signals, alarm signals, and Interlock logic, that the roasting process is finalized with the maximum reduction of risks in emergencies
ENVIRONMENT COST-BENEFITLEOGAP roasters recirculate the liberated gases in the roasting process and use their thermal energy to create an environmentally friendly environment. The surplus gases are partially used to dry the coffee and, then, after the treatment, they are released into the environment attending to the ecological requirements. For the roaster the following configurations are highlighted:
- Reduced energy and fuel consumption due to heat recirculation
- Reduced energy, fuel consumption, and increased productivity with a pre-drying system
- Reduction in emission values and adherence to local limits
- Minimum heat loss due to an excellent isolation system
- Retention of the chaff from the roasting and drying process
SafetyLEOGAP´s safety technology goes far beyond standard requirements. We offer high-quality components that guarantee maximum process safety.
- Automatic safety supervision system, with simple and safe operations even in extremely dark roasts with low-quality green coffee
- Anti-condensation system in order to prevent the formation of crust and reduce the risk of fire
- The temperatures of the critical points of the Roaster are permanently monitored
- Alarm system and parameterized setpoints for operational safety
- Automatic injection of water in case of emergency
