New advancements in coffee hulling and peeling technology: faster, cleaner, and more efficient.

By Yetinhon Coffee Equipment Team--November 26, 2025

As global coffee consumption continues to grow, coffee bean processing is also undergoing technological innovation. Recently, several equipment manufacturers have launched a new generation of coffee hulling machines, which significantly improve efficiency, reduce breakage rates, and enhance cleanliness and operability, providing coffee growers, processors, and roasters with new productivity tools.

 Why is upgrading the shelling technology important

• The coffee industry is moving from small-scale manual processing to mechanization, large-scale production, and modernization, with efficiency and production capacity demands increasing simultaneously. Traditional manual or crude mechanical hulling is inefficient and time-consuming, making it difficult to meet growing production demands. According to research and industry reports, mechanized hulling has fundamentally changed coffee production methods, making large-scale, standardized processing possible.
• Ensuring quality and bean integrity is crucial.
•  Improper control during the hulling process can lead to coffee bean breakage and powdering, affecting subsequent roasting and flavor stability. The new equipment, through optimized design—such as reduced friction, lower vibration, and enclosed operation—significantly reduces bean cracking and dust generation while ensuring clean separation of the husk and bean.
• Yetinhon machines are designed with cleanliness, maintenance and energy efficiency in mind, which not only improves the working environment of the production line but also reduces long-term operating costs.

Features of the new generation of equipment: Taking Yetinhon's shelling machine as an example

Represented by Yetinhon's coffee bean hulling machine, its new models have the following features:

• High processing capacity —up to 800 kg/h, ideal for medium to large-sized coffee processing plants.
• High shelling rate + low breakage rate — The company claims a high shelling rate and a low breakage rate, ensuring that most beans remain intact.
• Automation and ease of operation —The equipment has an advanced structure that automatically separates the shells and beans, and is easy to maintain and clean.
• Cleanliness and environmental tidiness – Shells and beans are collected separately, reducing dust and impurities and improving the working environment.
• Adaptable to various bean types and flexible processing – the machine settings are adjustable to accommodate beans of different sizes, varieties, and moisture levels.

In addition to high-capacity models, Yetinhon also offers smaller capacity versions (such as a small huller that can handle about 50 kg/h), suitable for small and medium-sized farms, small-batch bakers, and other users.

Industry Trends: Emphasis on Automation, Efficiency, and Quality

According to market research and industry analysis, companies and factories are increasingly inclined to adopt mechanical shelling solutions that are "time-saving, labor-saving, and standardized." Some reports indicate that the new generation of shelling machines, by reducing friction and collisions and optimizing the separation system, can simultaneously achieve "high shelling rate + low energy consumption + low breakage rate."

In addition, with increasing global attention to food hygiene, safety, and environmental impact, equipment manufacturers are optimizing materials (such as stainless steel and food-grade materials), sealing, dust control, and noise control to meet stricter standards.

Significance to the industry chain and practitioners

• For growers/farmers : Using high-capacity hulling machines in medium to large-sized farms can significantly reduce labor costs, shorten processing cycles, and increase output.
• For processing plants/exporters : A stable and efficient hulling process means higher throughput, lower raw material loss, and cleaner, more intact beans for export or subsequent roasting.
• For roasters/coffee brand owners : Clean, undamaged beans make it easier to ensure roasting quality and flavor stability, which is beneficial for specialty coffee and mass production.
• For supply chain and sustainable development : Automated, low-waste, and high-efficiency equipment helps reduce resource waste and environmental pollution, which is in line with the trend of sustainable agricultural development.

 Conclusion

The coffee hulling process has long been a bottleneck in production; however, with manufacturers like Yetinhon continuously launching new, more efficient, cleaner, and automated models, hulling has transformed from a constraint into a key step driving industry upgrades. As global coffee consumption and the specialty coffee market continue to expand, these high-quality hulling machines will increasingly become the industry standard—enabling more people to transform "green beans" into "roastable beans" in a faster, cleaner, and higher-quality way.
