How to Choose the Best Selezionatrice Ottica Fagioli?

Evaluation Dimension	Compact Machine	Standard Production Machine	High-Capacity Machine	Why It Matters
Recommended Use	Small farms, laboratories, and seasonal processing	Regular commercial bean cleaning and grading	Industrial plants and continuous processing lines	The machine should match daily production volume rather than peak volume alone.
Nominal Throughput	0.5–1.5 tonnes per hour	1.5–4.0 tonnes per hour	4.0–8.0 tonnes per hour	Actual capacity depends on bean size, moisture, contamination, and the selected defect threshold.
Sorting Accuracy	Up to 99.0% under stable feed conditions	Up to 99.5% under stable feed conditions	Up to 99.8% with optimized calibration	Accuracy should be verified using the buyer’s own bean varieties and defect samples.
Typical Yield Loss	0.5–2.0%	0.3–1.5%	0.2–1.2%	Excessive product loss usually indicates poor calibration, uneven feeding, or an unsuitable air setting.
Camera Configuration	RGB color cameras	High-resolution RGB cameras with multi-channel lighting	RGB plus optional infrared or shape-detection systems	Advanced sensors can identify subtle discoloration, cracks, foreign material, and shape defects.
Suitable Bean Moisture	Typically 10–14%	Typically 10–14%	Typically 10–14%	Beans outside the recommended moisture range may bridge, smear, or produce inconsistent ejection.
Compressed-Air Requirement	0.8–1.5 m³/min at 0.6–0.8 MPa	1.5–3.0 m³/min at 0.6–0.8 MPa	3.0–6.0 m³/min at 0.6–0.8 MPa	Air quality and flow stability directly affect reject timing and product recovery.
Connected Electrical Load	Approximately 3–6 kW	Approximately 6–12 kW	Approximately 12–25 kW	Electrical capacity, compressor demand, and ventilation should be checked before installation.
Daily Cleaning Time	15–30 minutes	20–40 minutes	30–60 minutes	Routine cleaning reduces dust buildup, false rejects, and camera or ejector malfunctions.
Preventive Maintenance Interval	Every 500–1,000 operating hours	Every 500–1,000 operating hours	Every 500–800 operating hours	Intervals should include filter replacement, nozzle inspection, calibration, and electrical checks.
Operator Skill Level	Basic training	Basic to intermediate training	Intermediate to advanced training	Simple recipe management and clear alarms reduce setup errors and downtime.
Indicative Purchase Cost	US$20,000–50,000	US$50,000–120,000	US$120,000–250,000+	Final pricing varies with sensor type, number of channels, automation level, installation, and regional taxes.
Estimated Annual Service Cost	Approximately 3–6% of purchase cost	Approximately 4–7% of purchase cost	Approximately 5–8% of purchase cost	Budget for wear parts, filters, air-system servicing, calibration, software support, and technician visits.
Best Selection Criterion	Low initial cost and simple operation	Balanced capacity, accuracy, and operating cost	Maximum throughput and integration capability	Choose the lowest total-cost option that consistently meets quality and production targets.
