Recently, Hebei Yanming Chemical Equipment Co., Ltd. has custom-designed and manufactured 6  The single-cone vacuum dryer has successfully completed all factory‑acceptance tests and a no‑load trial run, and has been properly loaded for shipment. This batch of equipment was specifically designed and implemented for granular resin materials containing organic solvents such as methanol and toluene, leveraging independently optimized ribbon‑type heating and a sealed vacuum system, CIP A range of online cleaning technologies precisely address industry‑specific challenges such as excessive drying residues, material agglomeration, and difficult solvent removal in the processing of specialty polymer materials. These solutions are widely compatible with diverse material streams—including polyarylethers, fine resins, chemical powders, and pharmaceutical intermediates—providing mature, reliable, and fully enclosed drying systems for new‑material and fine‑chemical manufacturers.

I. Backed by cutting-edge manufacturing technologies and designed to meet national standards for pressure vessels, this equipment delivers premium quality.

This series of equipment is manufactured in strict compliance with GB150 Pressure vessel, HG/T20569 Mechanical stirring equipment, etc. 24  Designed and manufactured in accordance with national and industry standards, with rigorous, high‑standard control throughout the entire process—from material selection and fabrication to inspection.

Material and Finishing Process: All surfaces in contact with the product are made of S30408 Stainless steel, with the inner wall of the cylinder polished to an exceptionally high finish. Ra ≤ 0.2 mu m Non-stick material, easy to clean, and eliminates the risk of material residue contamination; the vessel body, heads, and flanges are all forged from genuine raw materials sourced from reputable manufacturers. All plates, pipes, and forgings are accompanied by material quality inspection reports upon arrival at the factory, and undergo multiple inspections before shipment, including hydrostatic testing, non-destructive testing, and re‑measurement of wall thickness. Designed for a minimum service life of… 15 Year.

Closed‑system safety configuration: standard equipped with an explosion‑proof variable‑frequency motor. +  Double-sided perfluoroether The Mechanical seal with a closed-loop water‑cooling system, ensuring leak‑free operation and high‑temperature resistance, suitable for handling flammable and explosive organic solvents. The discharge valve is a jacketed, hard‑seated hemispherical valve equipped with a nitrogen back‑blow feature, effectively preventing solvent vaporization and dust leakage at the source.

Optimized Design for Heat Exchange and Mixing: Uniform Heating Across the Entire Volume with No Cold Spots; Built-in Single Helical Ribbon +  Center screw +  Bottom‑discharge screw‑combined stirring structure, with precisely controlled clearance between the ribbon and the vessel wall. 15 ± 2mm It gently turns and conveys materials at low speed, ensuring uniform heating and preventing localized overheating that could lead to material charring. The equipment is equipped with a dual‑unit baghouse dust collection system, which efficiently captures particulate matter from the drying exhaust gases, meeting stringent environmental standards.

Intelligentization CIP Cleaning: Built-in in the body 360 ° Rotating cleaning ball, entire body CIP Online cleaning eliminates the need for disassembly and manual cleaning, supports multi‑product production with frequent material changes, significantly reduces changeover time, and aligns with the demands of lean manufacturing.

Smart Integration DCS All system instruments, temperature controls, and pressure monitoring components are sourced from leading‑brand parts, and equipment operating parameters can be seamlessly integrated into the customer’s plant network. DCS The control system automates the regulation of drying temperature, vacuum level, and rotational speed, minimizing manual intervention and enhancing production stability.

2. The equipment boasts exceptional versatility, capable of handling materials across four major sectors.

High-end new materials: PEEK , various aromatic resin granules and powders such as polyphenylene ether and polyimide;

Fine chemicals: agrochemical active ingredients, catalysts, and inorganic salt crystallization products (with alcohol-based and aromatic solvents);

Pharmaceutical raw materials: active pharmaceutical ingredient intermediates, crystalline drug powders, and dehydration and solvent removal from wet materials.

Food additives: functional powders and plant extracts are dried at low temperatures.

Targeting High-solvent, easily oxidizable, and heat-sensitive materials The equipment employs a negative-pressure, low-temperature drying process that both ensures high solvent recovery and preserves the material’s physicochemical properties, thereby addressing common industry challenges such as low drying efficiency, excessive residual solvents, and compromised product appearance associated with conventional ovens.

III. Rigorous factory‑level quality inspections and comprehensive end-to-end service support

6  Prior to shipment, the equipment shall undergo drawing verification, nondestructive testing, static balancing of the shafting, and a full‑machine water‑load integrated test run; only after vibration, noise, and sealing leakage all meet the specified standards may it be released for delivery. Concurrently with delivery, the complete set of supervision and inspection documents for the pressure vessels shall also be provided. CAD Equipment drawings, list of wear parts, motor /  Mechanical seal /  Original manufacturer’s certificate of conformity for the valve, and the equipment installation, operation, and maintenance manual.

The company offers end-to-end technical services: free small-scale material trials and customized process solutions in the early stage; on-site guidance for equipment installation, commissioning, and production launch in the mid-stage; and full-machine warranty in the later stage. +  Long-term maintenance of critical components and on-site technical upgrades tailored to your needs help production‑ready enterprises ramp up output swiftly.

IV. Industry Outlook

Currently, the localization of new materials in China is accelerating. Polyarylether, specialty resins As production capacity for high-end materials continues to expand, downstream manufacturers’ demand for closed‑system, low‑residue, intelligent drying equipment has been rising year after year. Yanming Equipment has long been dedicated to the R&D and manufacturing of vacuum drying systems, continuously refining equipment designs to suit the physicochemical properties of various materials, thereby reducing reliance on imported high‑end drying solutions. The successful delivery of this batch of equipment not only underscores our customers’ recognition of our technical expertise but also marks the establishment of standardized, field‑proven products in the solvent‑based polymer drying segment. Moving forward, we will remain committed to advancing in the fine chemicals and new materials sectors, offering customized single‑cone drying solutions to clients across industries nationwide. Companies facing challenges in material drying are welcome to conduct trial runs with their own materials and visit our facility to inspect prototype units on site.

We have established a standardized testing center that supports customers in conducting laboratory experiments. Clients can bring their actual materials for on-site testing, with data fully recorded and comparative analysis reports provided. In addition, we offer free technical consulting and customized drying process packages, truly enabling a tailored solution for each material—tested and ready to use immediately.
