Beyond a handful of hives, time per colony — not money per colony — becomes the binding constraint. Two of the biggest time-savers a scaled apiary can buy are faster extraction and remote hive monitoring.
throughput = manual: 40 frames/hr (fixed)
radial: 40 + (RPM − 150) × 0.46 frames/hr
hours = (colonies × 8 frames/colony) / throughput
visits/week = ceil(colonies / 10) × (sensors ? 0.3 : 1)
- Apiary size — total colonies managed; drives both the extraction workload and the base visit count.
- Extractor type — a manual tangential extractor processes frames at a fixed rate; a motorised radial extractor's throughput scales with drum speed.
- Extractor speed (RPM) — only changes the spin rate and throughput of the motorised radial extractor.
- Remote sensors — electronic hive-scale and temperature sensors catch a stalled nectar flow or possible queenlessness remotely, cutting the physical visits still needed to roughly 30%.
Real-world relevance: many UK beekeepers find a motorised radial extractor starts to pay for itself once they're running twenty to thirty colonies or more.
