# Potato Intake Quality Gate: What to Define Before Cleaning

## Key takeaways

- Agree destination, acceptance conditions and decision authority before cleaning.
- Separate removable contamination from crop defects and size requirements.
- Use consistent sampling and trial logs to assess each process stage.
- Assign accept, reroute, hold or reject actions to unresolved conditions.

## Define the receiving decision before cleaning

Before cleaning, define the destination, the conditions to inspect and the action each finding requires. A potato intake quality gate should lead to a clear lot decision: accept for the intended route, reroute, hold for review or reject.

Agree categories for attached soil, loose foreign material, size spread and visible damage. Purchasing, receiving and production staff should use the same descriptions. Set destination-specific acceptance conditions with the supplier or customer before delivery rather than inventing universal limits. Where descriptions could be interpreted differently, use agreed reference photographs or written examples. Specify whether each finding triggers further sampling, a process trial or an immediate lot decision, so receiving staff can act consistently.

Name the person authorized to release a held lot and identify where it will remain pending review. Record the decision before mixing lots, so the original condition and intended destination remain traceable in the receiving log. If unloading must continue during review, agree how the lot will remain separate and identifiable. A hold instruction should include the unresolved question, the person responsible for answering it and the evidence needed for release.

- Name the destination for each lot.
- Agree observable acceptance categories.
- Assign decision and release authority.
- Define accepted, held and rejected routes.

## Separate contamination from crop condition

Record loose soil separately from soil attached to potatoes. Name foreign material observed in the sample rather than recording only “dirty crop.” Cleaning and separation can address removable contamination, but suitability depends on the actual material and its condition. Describe whether material is loose, attached or mixed through the sampled potatoes. These observations help define the removal duty and the points to examine during a trial; they do not establish that every contaminant will be removed.

Visible cuts, green areas and other agreed defects need a separate decision. Cleaning does not repair damaged potatoes. Some damage may be hidden or become easier to see after cleaning, so intake observations alone cannot establish every defect present.

Size spread is primarily a destination and grading question. Record the incoming range using an agreed method, then decide whether it suits the intended route. The [guide to sizing a potato cleaning intake line](https://www.spudmate.com/how-to-size-potato-cleaning-intake-line/) connects incoming conditions with the flow requirement.

- Separate loose soil from attached soil.
- Name the foreign material observed.
- Record visible defects separately.
- Assess size against destination requirements.

## Assign cleaning and manual inspection duties

The [BQX cleaning machine range](https://www.spudmate.com/products/potato-cleaning-machine-bqx/) receives bulk potatoes and feeds a hydraulic cleaning roller. Soft PU spiral blades, adjustable roller spacing and a double-layer impurity conveyor support cleaning and separation. Trial results should establish suitability for the intended incoming material.

The [potato selection platform](https://www.spudmate.com/products/potato-selection-platform/) uses chain-driven stainless rollers. Friction rotates each potato through 360° while workers remove bad potatoes to a central waste channel. The inspection task still needs agreed defect categories and a suitable feed arrangement.

Choose the sequence around visibility and removal duties. Cleaning before inspection may expose surfaces obscured by soil. When incoming potatoes are already clean, assess whether manual selection addresses the main issue before adding another cleaning stage.

- Define the mechanical removal duty.
- Define the manual defect decision.
- Plan separate waste discharge routes.
- Match inspection to the destination.

## Match component roles to the required flow

BQX model ratings exceed the selection platform’s stated 5–15 t/h range, where t/h means metric tonnes per hour. If the route requires manual inspection, that stage may constrain flow. A cleaning rating alone cannot establish how much inspected, accepted product the route will deliver. Define the target as incoming feed or accepted output, and record both separately during a trial. Soil, foreign material and rejected potatoes leave through other routes, so accepted output need not equal incoming feed.

The [inbound and outbound sorting line](https://www.spudmate.com/products/potato-inbound-outbound-sorting-line/) combines cleaning, dry cleaning, manual selection, lifting, sorting, conveying and bagging duties. It can be configured for storage intake or direct packing, and individual stages can operate independently. Capacity remains project-specific.

Review utilities and footprint alongside the process duty. BQX models list AC380V/50Hz; the selection platform lists 220 V and an adjustable height of 960–1300 mm. A qualified local electrical professional should assess the installation requirements.

| Equipment | Stated capacity | Process duty | Planning implication |
| --- | --- | --- | --- |
| BQX-16 | 40 t/h | Bulk cleaning and impurity separation | Check suitability with the incoming crop. |
| BQX-20 | 60 t/h | Bulk cleaning and impurity separation | Match downstream duties to the required flow. |
| BQX-24 | >90 t/h | Bulk cleaning and impurity separation | This rating does not establish inspected output. |
| Selection platform | 5–15 t/h | Manual inspection and removal | Assess visibility, staffing and feed conditions. |
| Inbound and outbound sorting line | Project-specific | Configured cleaning, sorting and packing | Agree line capacity; do not add component ratings. |

## Agree sampling before the delivery arrives

Agree where samples will be taken, how much will be examined and how results will inform the lot decision. Observations from the beginning, middle and end of unloading can help reveal variation; they do not automatically establish a representative sample.

Record lot identity, destination, receiving time, sampling location and the agreed condition categories. Use counts, masses or size measurements only with a defined method and units. For a count-based result, record the number examined as well as the number in each category. For a mass-based result, state what was weighed and whether the basis includes soil and foreign material. Keep observations separate from the final accept, hold, reroute or reject decision.

Compare observations before cleaning, after cleaning and after inspection using consistent categories. This helps assess each stage’s contribution. Plan how samples at different stages will relate to the same lot, allowing for material moving through the route between observations. Differences between samples may also reflect variation within the lot, so retain the sampling details when interpreting a trial. Avoid treating unmatched samples as a measured removal result.

- Agree sampling locations and quantities.
- Record lot identity and destination.
- Use consistent observation categories.
- Keep each sampling stage identifiable.

## Plan the hand-off and destination routes

Uneven feed or overlapping potatoes can make inspection harder. During layout review, consider how potatoes reach the rollers, what workers can see and where removed potatoes go. These are site planning questions to resolve alongside the equipment choice.

Specify transfer direction, impurity discharge, waste-channel destination and access for the inspection task. Check that rejected material cannot inadvertently return to accepted product. A bypass should have an agreed receiving decision and destination before it is used. Mark the intended destinations in the operating instructions and confirm them during the trial. These are process arrangements to agree for the site; they do not establish installed routing controls or automatic lot segregation.

Storage intake and direct packing may share equipment while requiring different acceptance decisions. Document both routes and test their hand-offs using the [commissioning checklist for potato conveying and sorting](https://www.spudmate.com/commissioning-checklist-potato-conveying-sorting/).

## Test the agreed receiving route

Agree the trial method and acceptance criteria before running material. Identify the crop lot, incoming condition, intended feed rate, operator arrangement and output destinations. Check the material path and discharge routes before starting the controlled material trial.

Observe cleaning discharge, surface visibility at inspection and separation of rejected potatoes. Record actual operating conditions and any changes made during the trial. If evaluating removal, define the sampling method and measurement basis before comparing incoming and outgoing observations. Where practical, change one process setting at a time and record the reason, so the team can interpret the result. Use comparable observation periods and identify interruptions; a brief peak flow does not establish sustained performance.

Compare the result with the agreed destination requirements. Record unresolved conditions and who must decide the next action. Follow-up may involve feed arrangement, inspection instructions or a supplier acceptance discussion; a machine adjustment cannot resolve every crop condition.

- Record the crop and trial conditions.
- Check impurity and reject discharge.
- Observe inspection at the tested flow.
- Assign actions for unresolved findings.

| Observation | Check | Process response | Lot decision |
| --- | --- | --- | --- |
| Loose or attached soil | Can cleaning address the sampled condition? | Trial cleaning and impurity discharge. | Accept for the route or hold for review. |
| Foreign material | What material is present and where does it discharge? | Assess separation with the actual material. | Hold unresolved contamination for an authorized decision. |
| Visible defects | Does the lot meet destination conditions? | Assess manual removal where appropriate. | Accept, reroute or reject against the agreement. |
| Wide size spread | Does the destination require a defined range? | Assess grading or another destination. | Route against the agreed size requirement. |
| Uncertain sample result | Is further sampling or review required? | Keep the lot identifiable pending review. | Release only through the agreed authority. |

## Keep crop acceptance separate from equipment acceptance

Equipment acceptance asks whether the configured route performs its agreed duties under the tested conditions. Crop acceptance asks whether the incoming lot suits its destination. Keep both decisions in the trial log, with the responsible person identified for each.

A foreign material type that remains after cleaning, a defect hidden by soil or an unsuitable size range needs a recorded disposition. Where the result is uncertain, use the agreed hold-and-review process before releasing the lot downstream.
