About Hangzhou Ayan Instrument Manufacturing Co., Ltd. - Industrial Machinery Supplier in China

China hosts Hangzhou Ayan Instrument Manufacturing Co., Ltd., which currently lists ten active products across four broad categories: Industrial Machinery, Light & Medium Machinery, Window Films & Screens, and Industrial Laminates. The catalogue includes five variants of thin‑film evaporators, two molecular distillation systems, two nitrogen‑blowing instruments, and a dedicated essential‑oil extraction machine. Each product is identified by its functional description rather than model numbers, indicating a focus on bespoke or custom‑engineered equipment. The supplier’s portfolio therefore spans vacuum‑based separation technology, inert‑gas handling, and extraction solutions used in chemical, pharmaceutical, and food processing environments.

The thin‑film evaporator entries comprise both glass and stainless‑steel constructions, reflecting common material choices for corrosion resistance and thermal stability. Molecular distillation units listed are described as short‑path or wiped‑film designs, which are typical for high‑purity, low‑temperature separations of heat‑sensitive compounds. Nitrogen blowing instruments are positioned for inert‑gas applications such as packaging or blanketing, while the essential‑oil and plant‑oil extraction machines target botanical processing. Waste‑oil distillation equipment completes the set, addressing industrial oil reclamation needs. All ten items fall under machinery HS chapters 84‑85, which cover industrial equipment and related components.

Product Range and Specialties of Hangzhou Ayan Instrument Manufacturing Co., Ltd.

The catalogue’s focus on thin‑film and molecular distillation aligns with industry standards that specify vacuum levels of 0.1  -  5 mbar, feed rates from 0.5 to 5 L h⁻¹, and material grades such as 304/316 stainless steel for corrosion‑prone streams. Typical evaporator modules are offered in capacities ranging from 5 L to 50 L per batch, with temperature control accuracy of ±1 °C. Wiped‑film designs often incorporate ceramic‑coated rollers to minimize product adhesion and enable continuous operation. Nitrogen blowing instruments generally deliver flow rates between 10 and 200 Nm³ h⁻¹ and include purity filters to achieve 99.99 % nitrogen. Extraction machines for essential and plant oils commonly employ screw or hydraulic presses, with pre‑heating zones up to 80 °C and filtration stages that meet food‑grade standards. Waste‑oil distillation units are built for feedstocks containing up to 30 % water and include condensate recovery systems.

In the broader industrial machinery market, buyers frequently request compliance documentation such as ISO 9001 quality management certificates, CE marking for EU entry, and RoHS declarations for electronic controls. For equipment handling hazardous or volatile substances, safety certifications like ATEX or IECEx may be required. Performance data sheets normally list vacuum pump specifications, heating element power (kW), material compatibility charts, and dimensional drawings to verify plant fit‑up. Suppliers often provide optional accessories such as automated control panels, PLC integration, and custom‑made stainless‑steel jackets to meet specific process needs.

Trade and Export Information - Hangzhou Ayan Instrument Manufacturing Co., Ltd.

China is a major exporter of process‑equipment, and thin‑film evaporators as well as molecular distillation systems are routinely shipped to Europe, North America, and Southeast Asian markets where high‑purity pharmaceuticals and specialty chemicals are produced. HS code 8421 covers vacuum pumps and related apparatus, while HS 8422 includes other machinery for fluid processing; both codes are commonly applied to the types of equipment listed by Hangzhou Ayan. Buyers typically request CE conformity for EU destinations, while US importers look for compliance with FDA‑listed equipment standards when the machines are used for food‑grade extraction. Freight is usually arranged in 20‑ft or 40‑ft containers with crating that meets ISPM 15 for wooden pallets, and Incoterms such as FOB Hangzhou or CIF Shanghai are standard for these heavy‑duty units.

Export logistics from China often involve pre‑shipment inspection under the China Inspection and Quarantine (CIQ) regime, especially for equipment destined for regulated industries. Documentation generally includes a commercial invoice, packing list, Bill of Lading, and certificates of origin. For high‑value machinery, buyers may also request a third‑party factory audit report and a performance test certificate issued by an accredited lab. The combination of robust packaging, clear HS classification, and adherence to international safety standards facilitates smooth customs clearance in target markets.

Sourcing from Hangzhou Ayan Instrument Manufacturing Co., Ltd. - Buyer Guidance

When sourcing from Hangzhou Ayan, request detailed product datasheets that specify vacuum level, temperature range, material construction, and power consumption. Verify that the supplier can provide CE or ISO certificates, and ask for a recent factory audit report to confirm quality management compliance. It is advisable to obtain a sample of the nitrogen output or a performance test report for the distillation units to ensure the advertised purity and throughput meet your process specifications.

Typical minimum order quantities for custom‑engineered machinery start at one unit, but lead times can range from 8 weeks for standard configurations to 20 weeks for fully bespoke designs. Confirm packaging details - most units are shipped on custom steel frames or wooden crates with shock‑absorbing padding - and clarify the Incoterm to allocate freight and insurance responsibilities. Prior to finalizing the order, request a pre‑shipment inspection report and, where applicable, a compliance declaration for ATEX or IECEx if the equipment will operate in explosive atmospheres.
