Which sorting machine fits your farm?
This page helps you choose: which Karevo machine fits which sorting volume, what optical sorting changes compared with sorting by hand, and when an industrial plant is the better choice.
The three machines compared
What matters most is the volume you sort per hour. All three machines use the same AI detection and detect defects with an accuracy of about 95%.
| Machine | Throughput | Working Width | Suited to |
|---|---|---|---|
| Karevo Uno40 Coming soon | 2–2.5 t/h | 40 cm | Smaller volumes and farms starting with optical sorting. In development, not yet orderable. |
| Karevo Duo85 | 5 t/h | 85 cm | Farms that sort up to 5 tonnes per hour. Available with or without a sorting table. |
| Karevo Trio110 | 10 t/h | 110 cm | Farms and packers that sort up to 10 tonnes per hour. Can be fitted into existing sorting lines. |
Throughput depends on the produce: with very large or irregularly shaped tubers the belt runs slower so that detection stays reliable.
Optical sorting or sorting by hand?
At the sorting table, quality depends on attention and on how the day is going. An optical sorter checks every tuber against the same criteria.
| Criterion | Sorting by hand | Optical sorting with Karevo |
|---|---|---|
| Consistency | Varies with fatigue and from day to day | The same criteria for every tuber, for the whole shift |
| Staff | Several people are tied to the sorting table | The machine sorts automatically, and staff are free for other work |
| Throughput | Limited by the number of people at the table | Up to 5 tonnes per hour (Duo85) or 10 tonnes per hour (Trio110) |
| Settings and records | Criteria are agreed verbally, and there are no statistics | Sorting strictness and defect size are adjustable, and the machine shows sorting statistics per batch |
| Limits | A person can also judge unusual cases | About 95% detection accuracy, not error-free sorting. The cleaner the tubers, the better the detection. |
When does an optical sorter pay for itself?
That depends on your farm. Four figures decide the calculation:
- Sorting hours per year: the more hours the machine runs, the sooner it pays for itself.
- Staff at the sorting table: the number of people and their hourly labour cost.
- Your buyer's requirements: with strict specifications, uniform lots and fewer complaints count for more.
- Grants and financing: depending on the country, investment grants, leasing or hire purchase can lower the initial outlay.
We state prices in our offer. We are happy to run the calculation with your figures.
Karevo or an industrial plant?
Industrial optical sorting plants are designed for large processors and storage operations. Karevo builds for family farms, direct marketers and packers.
| Criterion | Karevo | Industrial sorting plant |
|---|---|---|
| Designed for | Family farms, direct marketers and packers | Large processors and storage operations |
| Throughput | 2 to 10 tonnes per hour, depending on the machine | Designed for much higher volumes |
| Installation | A single machine that can also be fitted into existing lines. Installation usually takes one day. | Usually part of a complete plant |
| Price | Priced for small and medium-sized farms | Geared to large operations in capacity and price |
If you regularly sort more than 10 tonnes per hour on one line, or are planning a complete plant, an industrial plant fits better.
