When purchasing a coffee roaster, consider many factors. The following are detailed precautions:
First, clarify the needs and budget
Usage scenario: Home needs to consider space, noise and convenience; Commercial products focus on baking volume, efficiency and stability.
Budget range: entry-level (1-5 thousand yuan) suitable for beginners; Professional grade (10,000 to 100,000 yuan) to meet commercial needs; High-end customization (more than 100,000 yuan) suitable for large roastery.
Second, core performance parameters
Heating method
Hot air type: fast heating, high uniformity, suitable for shallow baking, but the flavor level is relatively thin.
Direct fire: The operation is difficult, can reproduce the Japanese deep smoke, suitable for hardcore players.
Semi-hot air type: The combination of roller heat conduction and hot air convection, balance the thickness and clarity, suitable for Italian mix and single bean.
Capacity selection
Home: microcomputer (50-200g) suitable for 1-2 families; Minicomputer (200-500g) to meet the needs of family weekly supply.
Commercial: more than one kilogram, need to have a cyclone dust bucket, such as commercial machine one hour to bake 4 POTS, a day to bake 8 hours, a day can bake about 30kg of cooked beans.
Temperature control accuracy
The accuracy of the temperature probe is ±1°C to ensure stable temperature during baking and avoid flavor bias.
Third, intelligence and controllability
Preset curve and APP interconnection: support mobile phone curve editing and sharing, one-click repeat champion baking solution, reduce the threshold of operation.
Real-time monitoring: It can synchronize temperature and damper data, and the touch screen of some models can adjust the roller speed for accurate control.
Degree of automation: Fully automatic models can realize the integration of beans, beans and beans, saving manpower and improving efficiency.
Fourth, detail design
Silver skin collection system: effectively collect the silver skin produced during the baking process to keep the environment clean.
Cooling efficiency: Independent cooling tray is 3 times faster than natural air cooling, avoiding excessive development of beans.
Noise reduction and smoke exhaust: preferentially choose models with decibels below 60dB, and solve the problem of smoke exhaust with kitchen range hoods.
Fifth, material and durability
Boiler material: cast iron heat storage is good, but the specific heat capacity of stainless steel is about 1.5 times that of cast iron material, and the heat absorption or heat dissipation capacity is weaker, and the heat storage effect is better under the same volume.
Roller material: stainless steel durable and good thermal conductivity, suitable for long-term use; Aluminum alloy is lightweight and easy to clean, suitable for frequent replacement users.
Key components: such as bearings, accessories, etc., need to choose high-quality materials to ensure the stability of the equipment under high strength use.
Sixth, brand and after-sales service
Brand reputation: Choose brands with good reputation and long-term market validation, and avoid buying off-brand or OEM products.
After-sales service: including warranty period, maintenance network coverage, technical guidance, etc., to ensure long-term stable operation of equipment.
Seventh, safety and compliance
Safety certification: Ensure that equipment meets national or regional safety standards, such as electrical safety, fire protection requirements, etc.
Environmental compliance: Pay attention to the energy consumption, smoke exhaust and other environmental indicators of the equipment, and comply with local environmental regulations.
Eighth, user evaluation and reputation
Actual use feedback: Learn about the advantages and disadvantages of the device by referring to other users’ experience.
Professional reviews: Review reports from professional organizations or baristas for more comprehensive information on equipment performance.
