# Small-Batch Potato Grading: Comparing 3–10 t/h Mechanical Options

**In practice:** Goldilocks guide to small-batch potato grading: how Potato mechanical sorting machine (3-10 t/h), Potato mechanical sorting machine BF4-11 and Potato mechanical sorting machine BF4-14 fit together, which operating points to set first, and what our engineers confirm before we prepare a line proposal.

## How we configure: small-batch potato grading

At Goldilocks, we configure small-batch potato grading around the hand-offs that control product quality and uptime. Potato mechanical sorting machine (3-10 t/h), Potato mechanical sorting machine BF4-11 and Potato mechanical sorting machine BF4-14 cover complementary steps; the practical choice is how they share flow, access and operator attention.

Start with crop condition, the hourly target and the quality decision the line must support. We select the first machine around that operating point. Place receiving, cleaning, inspection, storage and packing in a sequence that leaves room for service access, safe transfer and clear operator sightlines.

## Equipment used in this line

These are the models we normally review for this process. Capacity and dimensions set the first layout; our engineers then tune the line to the crop, target flow and site.

| Model | Capacity | Dimensions | Role |
| --- | --- | --- | --- |
| 5 t/h three-level; 5 t/h four-level; 10 t/h three-level; 10 t/h four-level | 3-5 t/h or 8-10 t/h according to configuration | 5 t/h three-level 7760 × 2700 × 1700 mm; 5 t/h four-level 8560 × 2500 × 1700 mm; 10 t/h three-level 7760 × 2800 × 1700 mm; 10 t/h four-level 8560 × 2800 × 1700 mm; adjustable height 1400-1800 mm | Mechanical potato grading before packing or storage |
| BF4-11 | Configured to project requirements | 4900 × 3900 × 1900 mm; effective roller width about 1100 mm | Four-level potato mechanical grading |
| BF4-14 | 60 t/h | 4900 × 4200 × 1900 mm | Four-level potato grading; sorting range 40-150 mm |

## How to plan the line

### 1. Start with the crop and flow

Start with crop condition, the hourly target and the quality decision the line must support. We select the first machine around that operating point.

### 2. Set the physical sequence

Place receiving, cleaning, inspection, storage and packing in a sequence that leaves room for service access, safe transfer and clear operator sightlines.

### 3. Prepare the project brief

Before we issue a final proposal, we confirm voltage, material condition, shift pattern, local safety requirements and the acceptance test for the installed line.

## Typical bottlenecks and our method

Small-batch grading rewards controllable changeover more than an oversized nameplate. The small mechanical sorter, BF4-11 and BF4-14 create a useful range for comparing feed preparation, screen or roller settings and discharge separation. The buyer should record the smallest lot, the number of grades and the time allowed between products before choosing the largest reference.

Most line problems start at a transfer: one machine is rated above the next module, wet produce carries soil into inspection, or a reject stream returns to the main flow. We solve this by sizing the hand-off, buffer and discharge together.

Our usual method is a controlled material trial. We set the feed rate, check drop height and belt or roller speed, tune variable-frequency drives where fitted, then record good and reject streams at each step.

Depending on the line, the technical review can include buffer volume, belt speed, roller gap, drop height, optical lighting, near-infrared detection, pneumatic reject response and acceptance sampling.

- material condition and size range
- target flow by hour and by shift
- available footprint and service access
- power, voltage and discharge direction
- the test method used to accept the line

## What we confirm before production

A reliable line starts with a clear project brief. We confirm the feedstock, moisture, size range, contamination, installation site and acceptance criteria before fixing the final arrangement or operating target.

Goldilocks configures each line after reviewing the crop, target throughput, layout, power and acceptance test. The product links above show the equipment used in this guide; contact us for a project-specific arrangement.
