The potato processing industry has seen booming demand for crispy potato chips, fries and deep-fried potato snacks across domestic food plants. One universal pain point troubling most processors is residual starch on sliced potatoes. Without proper cleaning and recycling, free starch ruins product quality, wastes water resources and raises environmental treatment costs. The potato slices flushing water starch separation centrifuge is engineered to tackle these challenges, becoming a vital piece of equipment for small and medium-sized domestic food factories.Traditional potato processing relies on long-time water soaking and static sedimentation pools to wash off starch. This outdated method requires large workshop areas, massive water input and extra workers to clean sediment regularly. Worse still, starch mixed in wastewater cannot be fully recovered, leading to lost by-product profits and high pollution load for sewage treatment systems. The all-in-one flushing and centrifugal separation machine completely upgrades this outdated production flow.
The equipment operates in a continuous automatic cycle. Freshly cut potato slices first pass through the circulating water flushing section, where high-speed water flow washes away free starch attached to slice surfaces. Clean potato slices are transported to the next cooking or frying procedure. Meanwhile, starch-rich flushing water flows into the centrifugal separation drum. Under powerful centrifugal force, fine starch particles gather and discharge as thick starch slurry, which can be dried, packaged and sold as a profitable secondary product. The filtered clean water is recycled back to the flushing tank, forming a closed water circulation system.
Built with food-grade 304 stainless steel, this centrifuge fully meets domestic food hygiene standards. Its compact layout fits limited factory space, with low power consumption and stable continuous operation suitable for daily mass production. In terms of practical benefits, it removes more than 90% surface starch to prevent potato slices from sticking together during frying, ensuring uniform golden color and crisp taste of finished snacks. Water recycling cuts fresh water usage greatly, while recovered starch brings stable extra income to food manufacturers.
From an environmental perspective, this centrifuge effectively reduces organic matter in discharged wastewater, helping domestic food plants comply with local environmental protection policies and avoid fines. It also lowers labor input, as automatic separation eliminates manual cleaning of sediment tanks.
For domestic food plant owners aiming to improve product competitiveness, cut operating costs and achieve green production, the potato slices flushing water starch separation centrifuge is a cost-efficient long-term investment. As the potato snack market keeps growing, this integrated separation device will continue to support local food manufacturers in boosting production efficiency and maximizing economic benefits.

GN Solids Control has secured a full turnkey order of 2600BBL rig solids control system for Kuwait drilling operations, marking another major breakthrough in the Middle East energy market. This comprehensive system order fully validates GN’s reliable engineering strength and long-term market recognition among high-standard Middle East oilfield clients.

As an official KOC (Kuwait Oil Company) approved solids control manufacturer, GN is qualified to directly supply full-range mud treatment and solids control solutions for Kuwait national oil projects. KOC supplier approval represents the highest industry threshold in Kuwait’s strictly regulated oilfield supply chain, reserved only for field-proven, technically compliant and stable global manufacturers.

The fully loaded 2600BBL integrated system covers complete drilling solids removal and mud circulation workflows. It assembles core processing units, including high-performance shale shaker, desander, desilter, drilling degasser and high-precision decanter centrifuge, achieving multi-stage precise purification of drilling mud.

Tailored for the extreme high-temperature and dusty environment of Middle East oilfields, the system’s entire electrical control unit adopts ATEX explosion-proof design. Compliant with international industrial safety standards, the configuration ensures stable, continuous and safe operation under harsh desert working conditions, fully matching KOC’s rigorous onsite operational requirements.

This professional mud cleaning system realizes closed-loop mud recycling and efficient solid waste reduction. It effectively stabilizes mud performance, improves overall drilling efficiency, and reduces operational and waste disposal costs for oilfield projects.

From standalone solids control equipment to customized turnkey system packages, GN Solids Control leverages its KOC-approved qualification and mature global project experience. The company consistently delivers high-reliability, environment-friendly drilling solutions, empowering safer, more efficient and cost-effective oil and gas exploration across the Middle East and worldwide energy markets.

As global wastewater regulations grow stricter, municipal and industrial treatment facilities worldwide face a universal pain point: bulky, high-moisture sewage sludge that inflates transportation, landfill and incineration costs. The GN GNLW554 horizontal decanter centrifuge, engineered exclusively for overseas wastewater projects, delivers continuous, stable sludge dewatering and has become a trusted core unit for water treatment plants across Southeast Asia, Europe, the Middle East and Latin America GN Separation Equipment.
Unlike belt filter presses that occupy massive floor space or chamber filter presses requiring frequent manual handling, the GNLW554 features a compact skid-mounted design with a 554mm bowl diameter, balancing high throughput and space efficiency. Powered by dual independent VFD motors, operators can freely adjust bowl rotation speed and scroll differential speed to match fluctuating sludge concentrations—whether handling thin domestic biosolids or thick industrial wastewater sludge. This precise control lifts cake dry solids by 4%–7% versus ordinary centrifuges, cutting sludge volume by over 60% and drastically lowering hauling and final disposal expenses for overseas plant operators.
Durability tailored for harsh overseas operating environments stands out as its core competitive edge. The spiral scroll is lined with tungsten carbide wear protection to resist abrasion from gritty sewage sludge, extending service life and slashing spare part replacement frequency. A thin-oil circulating lubrication system maintains constant bearing cooling during 24/7 non-stop operation, eliminating overheating risks common in tropical or desert wastewater facilities. Fully sealed housing controls odour leakage, helping plants comply with strict EU, ASEAN and North American environmental emission standards without extra deodorising equipment GN Separation Equipment.
Operation and after-sales are fully localized for global clients. Equipped with a PLC+HMI intelligent control cabinet, the machine supports automatic feed adjustment, fault self-diagnosis and remote monitoring, reducing on-site labour demands—critical for overseas plants short of skilled technicians. All electrical components meet international IEC certification, and complete seaworthy packaging ensures zero damage during long ocean shipping. GN Separation also provides multilingual operation manuals, overseas engineer commissioning and one-stop spare part supply networks for every regional market.
Sustainability runs through every design detail of the GNLW554. Optimized hydraulic flow cuts power consumption by nearly 18% compared to peer models, while clarified centrate water flows back to the front-end treatment process for recycling, lowering overall plant water intake. By minimizing sludge output, it also curbs carbon emissions from repeated sludge transportation, aligning with global net-zero and circular wastewater management targets.
For overseas wastewater plant investors seeking reliable, low-cost sludge dewatering equipment with full international compliance, the GNLW554 centrifuge strikes the perfect balance of performance, durability and global service support, solving sludge treatment bottlenecks for water facilities worldwide.
