Ruitu expands food-grade salt processing equipment line

Weifang Ruitu Automation Equipment Co., Ltd. is widening its salt processing capabilities with integrated systems for washing, crushing, drying, screening, conveying and packaging. The company is positioning these lines for food-grade salt producers that need flexible purification and production engineering across different raw salt types and plant sizes.

Why it matters: - Food-grade salt makers need tighter control over purity, moisture and particle size to keep production stable and finished product quality consistent. - Ruitu is targeting that need with integrated equipment and EPC services that connect purification to downstream handling in one production flow. - The company's approach is aimed at producers working with sea salt, lake salt and rock salt, which can require different treatment methods.

What happened: - Weifang Ruitu Automation Equipment Co., Ltd. said it is expanding its salt processing capabilities as a global food-grade salt making equipment manufacturer. - The company was established in 2015 in Weifang, Shandong Province. - Ruitu said its production area is about 28,000 square meters. - The company said it has more than a decade of experience in salt chemical equipment manufacturing. - Ruitu said its service scope includes process design, equipment manufacturing, installation, commissioning, training and production support. - The company said its project experience spans Africa, Europe, America, Central Asia and Southeast Asia. - More information is available at the company's announcement.

The details: - Ruitu's salt washing production lines are designed for crude salt purification and impurity removal. - The process uses a three-powder and four-wash method with spiral washing equipment. - Washing, suspension, sedimentation and dissolution work together to remove impurities while reducing salt loss. - Ruitu said its coarse salt purification lines can be customized for plant conditions and processing needs. - Available capacities range from 1 to 20 tons per hour. - The company's salt processing systems include raw salt feeding, conveying, washing, crushing, dewatering, drying, screening and packaging. - Equipment in the portfolio includes raw salt bins, screw conveyors, belt conveyors, screw washing machines, agitating salt washers, mixing and blending machines, counter-current washing machines, salt pumps, double-roll crushers, centrifugal dewatering equipment, hot-air heating systems and vibrating fluidized-bed dryers. - Ruitu's double-roll salt crushers are designed for primary and secondary crushing. - The crushers are applicable to food-grade salt washing plants, industrial salt production, refined salt production lines and larger salt washing facilities. - Ruitu combines centrifugal dewatering with hot-air heating and vibrating fluidized-bed drying to reduce residual moisture before storage and packaging. - The company's EPC model connects design and research with equipment manufacturing, procurement, installation, commissioning and training. - Ruitu's broader salt chemical equipment portfolio includes bromine extraction equipment, calcium chloride project equipment, magnesium chloride equipment, conveying equipment, general industrial equipment and steel-lined equipment. - Ruitu said its manufacturing facility includes laser cutting equipment, automatic welding systems, argon arc welding machines and lifting equipment. - The company said its management systems are certified to ISO 9001, ISO 14001 and ISO 45001. - Ruitu said inspection and quality control run from raw materials through finished products.

Between the lines: - The company's pitch is less about selling standalone machines and more about delivering a matched process line. - That matters because washing, dewatering, drying and screening need to be balanced to avoid bottlenecks and inconsistent output. - Ruitu is also signaling that different salt-processing routes serve different end uses, from washing-based purification to evaporation, crystallization, color sorting and vacuum refining. - The emphasis on customization suggests the company is competing on engineering fit as much as on equipment hardware.

What's next: - Ruitu said it will continue developing food-grade salt processing through equipment and engineering solutions centered on production requirements. - Future projects are expected to keep focusing on matching equipment configuration to raw salt type, plant layout, capacity and product specifications. - The company is likely to keep building complete production lines rather than only supplying single machines.

The bottom line: - Ruitu is positioning itself as a one-stop supplier for food-grade salt production, with purification, processing and EPC engineering tied together in one offering.
