Filling technology selection
Linear vs Rotary Filling Machine
A linear filler moves bottles along a straight path; a rotary filler carries them around a filling carousel. Neither arrangement determines the filling principle or best purchase by itself. Compare accepted bottles per shift for your actual SKU schedule, then check format parts, cleaning, access and retained equipment. There is no universal BPH threshold that makes one arrangement the correct choice.

When to Shortlist Linear or Rotary Filling
| Production question | Investigate linear when… | Investigate rotary when… |
|---|---|---|
| Production schedule | The proposed cycle meets required shift output across the planned batches. | The proposed carousel meets sustained output on the planned package family. |
| Bottle and cap variety | The specified guides, nozzles and closure adjustments cover the SKU list with manageable setup work. | Every required star wheel, guide, neck-handling and cap component is identified for that same list. |
| Product behavior | The valve or dosing system suits the beverage, viscosity, foam and particles. | The valve sequence and available filling time suit the beverage at the proposed carousel speed. |
| Layout and service | A straight conveying path fits the retained equipment and required access. | Carousel size, inlet/outlet orientation and maintenance zones fit the measured floor plan. |
| Changeovers and cleaning | Measured setup, cleaning and restart losses leave sufficient production time. | Those same measured losses remain acceptable; rotary does not automatically mean slow changeovers. |
| Expansion | The proposal states how output can increase and which modules would change. | The proposal states the supported rate range, format limits and surrounding-equipment needs. |

Worked Example: Nameplate Speed Is Not Shift Output
Illustrative arithmetic only—not Allot Tech ratings or typical linear/rotary performance. Assign these inputs to real proposals only after test evidence is available. Net output = running rate × productive hours × accepted-bottle fraction. Productive hours here already exclude setup and cleaning: do not deduct the same losses again through an efficiency factor.
| Input or result | Illustrative proposal A | Illustrative proposal B |
|---|---|---|
| Scheduled shift | 8 hours | 8 hours |
| Setup, cleaning and restart | 1 hour | 2 hours |
| Productive time after these losses | 7 hours | 6 hours |
| Running rate on the agreed bottle | 3,000 BPH | 4,000 BPH |
| Accepted-bottle fraction | 98% | 98% |
| Accepted bottles per shift | 3,000 × 7 × 0.98 = 20,580 | 4,000 × 6 × 0.98 = 23,520 |
| If B instead loses 3 hours to changeovers | Unchanged: 20,580 | 4,000 × 5 × 0.98 = 19,600 |

Ask Both Suppliers to Demonstrate the Same Job
- Run the same beverage, bottle, closure and fill basis; document the limits of any substitute test liquid.
- Time from the last accepted bottle of SKU A to the first accepted bottle of SKU B, including cleaning and restart rejects.
- Record accepted output, stops, rejects and operator interventions over an agreed duration.
- Show service access, cleaning connections, cap replenishment and format-part removal.
- Itemize format parts, controls handoffs, utilities and future-SKU exclusions.

Buyer questions
Frequently asked questions
Is a rotary filler automatically the better high-speed choice?
No. Product fit, package handling, format range, changeover, access, space and the sustainable output basis still determine the arrangement.
Is there one BPH threshold where rotary becomes better than linear?
No universal threshold applies. The decision changes with fill time, number of heads or valves, package formats, cleaning, changeovers, floor space and maintenance strategy.
Which arrangement is easier to change over?
That depends on the actual guide parts, recipes, filling heads or valves, closure system, tooling access and cleaning sequence. Require a demonstrated changeover method and time basis.
At what BPH should I switch from a linear to a rotary filler?
There is no universal cutoff. Compare machines on the same beverage, package, shift schedule, changeover workload and acceptance criteria. A speed quoted on a different bottle cannot establish which arrangement will deliver more accepted bottles in your shift.
