A Polyol Expansion Project—Dual-Line Operation, Tube Feeders Address Compliance Challenges

In a company's “10,000-ton Refined Functional Polyol and Powder/Granule Workshop Expansion Project,” the simultaneous construction of pharmaceutical and food production lines presents dual challenges for feeding equipment.

Pain Points and Requirements:

The materials transported on both lines possessed entirely different characteristics (sorbitol granules versus sugar alcohol powder). The system needed to prevent blockages from large particles while also suppressing dust emissions from fine powders. Additionally, the pharmaceutical line must comply with GMP standards, requiring equipment that is easy to clean with no dead corners.

Solution:

The project adopted tubular vibrating feeders, whose core design perfectly addressed these requirements:

Material Graded Application: To meet compliance requirements for different lines, components contacting pharmaceutical materials used SUS316L stainless steel, while the food line employed SUS304 stainless steel. All material-contact surfaces were polished to Ra0.4μm, with non-contact surfaces polished to Ra0.8μm, eliminating cleaning dead zones entirely.

Sealing and Dust Protection: The fully enclosed tubular design with flange connections and high-performance seals ensures zero dust leakage during conveyance while meeting requirements for transporting fine powders and granules.

Significant Application Value:

Compliance: The equipment successfully passed both GMP and food-grade inspections.

Cleaning Efficiency: The dead-zone-free design reduces equipment cleaning time by 50%.

Maintenance Costs: High-quality motors and vibration-damping design extend maintenance cycles to 12 months, lowering annual maintenance costs by 60%.

Ensures product safety through 304/316L stainless steel construction; guarantees production quality via high-precision control systems; enhances cleaning efficiency with quick-release and dead-zone-free design.
