Optical sorting pays for itself

Optical sorting is rapidly becoming an indispensable link in modern potato cultivation. While sorting lines were traditionally primarily mechanical, cameras and smart software are delivering demonstrably better results.

This progress translates not only into higher sorting quality and capacity, but above all into hard cash. Especially in a year when oversized seed potatoes yield little, precision is crucial. to sort immediately see the difference in returns.

More seed potatoes in the right size = direct additional yield
The financial benefit of optical sorting begins with higher accuracy in size separation. Optical size sorters assess each potato individually based on multiple camera images. They consider not only diameter but also length, volume, and shape. This results in much cleaner separation than mechanical sorting.

Tests show that the optical size sorter Optica CS Sorts up to 25% more accurately than mechanical shaking or shock sorting machines, especially with elongated varieties like Spunta and Agria. In practice, this means significantly fewer seed potatoes are wrongly classified as oversized or other less-paid sizes. Especially in the current season, when oversized seed potatoes have little value, this provides a clear financial advantage.

Every percent of extra seed potatoes in the right size counts. For larger volumes, an improvement of a few percent can quickly add up to tens of tons of additional marketable seed potatoes in the desired size class.

Less shift to cheaper sizes
Mechanical sorters operate with fixed mesh sizes and are therefore more susceptible to shape deviations. Elongated potatoes "bump" across the sorting screens and end up in the wrong bunker or bin. Optical sorting prevents this shifting and ensures the correct size of potatoes.

The increased accuracy allows for more product retention in the standard seed sizes. This reduces the proportion of oversize and increases the average yield per ton. Optical sorting thus acts as a yield accelerator: not by increasing production, but by making better use of what is already available.

Calculation example: benefit per hectare
The financial benefit of more accurate optical sorting can also be clearly demonstrated on a per-hectare basis. Consider a seed potato plot where, after sorting, 10 tons per hectare end up in the oversize. Suppose that in the current season, the oversize might only yield an average of €0,025 per kilo, while seed potatoes in the standard seed potato sizes are worth approximately €0,25 per kilo.

If optical sorting with the Optica CS ensures that 20% of this oversize is still correctly classified as the seed potato size, this amounts to 2.000 kilos per hectare that will be given a different destination.

The price difference in this example is €0,225 per kilo. This results in an additional yield of: 2.000 kg × €0,225 = €450 per hectare

And that difference is created purely by more accurate sorting, without additional cultivation costs. At the farm level, with large acreages of seed potatoes, this advantage quickly adds up to tens of thousands of euros. Especially in years when the oversize has little value, this calculation example demonstrates the significant impact optical sorting can have on the final result.

Labor savings with measurable effect
In addition to improved size separation, optical sorting also provides significant savings on labor costs. Optical quality sorters such as the Optics Q Automatically detect diseases, defects, clods, and shape deviations. Manual proofreading is significantly reduced or even unnecessary.

Fewer people on the sorting line means lower personnel costs and less reliance on scarce labor. At the same time, sorting quality remains consistently high, regardless of the number of operating hours. Financially, this labor saving contributes substantially to the investment's payback period.

Higher capacity, lower costs per ton
Modern sorting lines with optical technology handle higher tonnages per hour. This allows the sorting process to be organized more efficiently and concentrated in shorter periods. This reduces energy consumption, logistics, and handling.

Furthermore, optical sorting offers flexibility. Batches can be processed with different settings, depending on variety, market, and delivery time. This flexibility allows for strategic sorting and thus optimally responding to pricing.

Data as an additional revenue model
An additional advantage of optical sorting is the availability of detailed data. Every potato that passes through the conveyor belt is recorded. Insight into size distribution, quality, and failure rates allows for more precise management of cultivation, storage, and planning.

This data supports better decisions, such as area allocation and delivery strategy. This means that optical sorting not only contributes to today's yield but also to a structurally higher return in the future.

Investment that pays for itself
Although the investment in optical sorting technology is higher than for a traditional sorting line, the payback period in practice is often short. Higher accuracy, up to 25% more seed potatoes of the correct size, lower labor costs, and more efficient processing make the calculations compelling.

In a market where margins are under pressure and oversize potatoes yield little, optical sorting isn't a luxury, but a strategic choice. It ensures that every potato yields maximum returns and makes sorting a direct contribution to the bottom line.
