In the global walnut processing industry, efficiency and product quality are the core factors determining enterprise profitability. For large-scale walnut processors, choosing a high-performance
industrial walnut shelling line can not only solve the pain points of low efficiency and high kernel breakage rate but also significantly improve profit margins. This case study focuses on a Romanian walnut processing factory that upgraded its production line with our
industrial walnut shelling line, achieving a 35% profit increase and setting a benchmark for the European walnut processing industry.
The Romanian factory, founded in 2018, mainly engages in the processing and export of shelled walnuts, with an annual processing capacity of 12,000 metric tons. Before upgrading the industrial walnut shelling line, the factory used traditional mechanical shelling equipment, which exposed many problems: low shelling efficiency (only 500 kg per hour), high kernel breakage rate (up to 18%), and high labor costs (needing 15 operators per shift to sort kernels and separate shells). These problems led to high processing costs and low product quality, making it difficult for the factory to compete in the European high-end walnut market.
In early 2025, the factory decided to upgrade its processing line and finally chose our industrial walnut shelling line after comparing multiple suppliers. Our industrial walnut shelling line integrates pre-cleaning, grading, shelling, shell-kernel separation, and kernel sorting, with a daily processing capacity of 500 metric tons, which is 10 times that of the traditional equipment. The core advantage of the industrial walnut shelling line lies in its AI-driven pressure adjustment and negative pressure shell separation technology, which can accurately adapt to different sizes of walnuts and minimize kernel damage.
After 6 months of operation, the Romanian factory achieved remarkable results with the industrial walnut shelling line. First, the shelling efficiency was greatly improved: the hourly processing capacity increased from 500 kg to 5,000 kg, and the daily processing time was shortened from 12 hours to 8 hours, reducing the operation time by 33%. Second, the kernel quality was significantly improved: the kernel breakage rate decreased from 18% to 3.2%, and the whole kernel rate increased from 65% to 92%, which made the factory’s shelled walnuts eligible for the high-end European market, and the product price increased by 20%.
In addition, the industrial walnut shelling line also helped the factory reduce labor and energy costs. The fully automated design of the line reduced the number of operators per shift from 15 to 4, saving 73% of labor costs. At the same time, the energy-saving technology of the industrial walnut shelling line reduced energy consumption by 30% compared with traditional equipment, further reducing the factory’s operational burden. According to the factory’s financial data, after upgrading the industrial walnut shelling line, the total processing cost per metric ton of walnuts decreased by 18%, and the overall profit increased by 35% compared with the same period last year.
“The upgrade of the industrial walnut shelling line has completely changed our production status,” said the factory manager. “Not only has the production efficiency been greatly improved, but the product quality has also reached the European high-end standard, which has helped us expand the market share in Germany, France, and other countries. The industrial walnut shelling line is indeed a core asset for our factory to improve competitiveness.”
The success of this Romanian factory fully proves the value of a high-quality industrial walnut shelling line for large-scale walnut processors.
