Introduction
Changzhou Xinggan Drying Equipment Co., Ltd. (常州市星干干燥设备有限公司) is a Chinese manufacturer of industrial process equipment specializing in drying, mixing, granulation, dust collection, cooling, and related thermal-processing systems. The company is headquartered in Jiaoxi Industrial Park, Zhenglu Town, Tianning District, Changzhou, Jiangsu Province, an important manufacturing region in eastern China.
Established in 2002, Xinggan serves industries in which controlled moisture removal and powder handling are essential, including pharmaceuticals, chemicals, food processing, agricultural products, textiles, electronics, environmental protection, and selected mineral-processing applications. Its product portfolio includes spray dryers, belt dryers, fluidized-bed dryers, vacuum dryers, flash dryers, rotary dryers, ovens, mixers, granulators, and ancillary equipment.
Within the plastics and broader process-equipment ecosystem, the company occupies a supporting role rather than producing polymers or finished plastic products. Its equipment can be used to dry polymer powders, additives, pigments, chemical intermediates, and other materials before compounding, extrusion, molding, or packaging. This places Xinggan within the industrial machinery segment that helps plastics manufacturers control moisture, improve material consistency, and meet process-quality requirements.
History and Development
Xinggan developed during the expansion of China’s specialized process-equipment manufacturing sector. Its activities have centered on the design, manufacture, and development of drying, mixing, granulating, and associated systems.
Several milestones characterize its development:
- 2002: The company was established, according to its corporate profile.
- Industrial-scale manufacturing expansion: Company and industry-directory profiles describe a manufacturing site in Changzhou covering approximately 46,000–50,000 square metres, with a substantial workshop area and more than 80 sets of lifting, cutting, welding, machining, and inspection equipment.
- International and sector diversification: Xinggan’s equipment portfolio expanded beyond basic hot-air ovens to include spray, fluidized-bed, vacuum, flash, belt, rotary, and hollow-blade drying systems, supporting pharmaceutical, chemical, food, agricultural, textile, and electronics applications.
- Industry participation: The company has exhibited at professional machinery events, including pharmaceutical-equipment exhibitions, reflecting its connection with regulated process industries.
The company’s development follows a broader industry trend: customers increasingly require complete process lines rather than isolated machines. Drying equipment suppliers therefore compete through engineering integration, process customization, material compatibility, energy management, and after-sales support.
Business Operations and Manufacturing Base

Products and Technologies
Drying Equipment
Xinggan offers several drying technologies, each suited to different feed materials and production conditions:
- Spray dryers: Liquid feeds are atomized into a heated gas stream, producing powders through rapid moisture evaporation. High-speed centrifugal spray dryers are commonly used for solutions, emulsions, suspensions, and heat-sensitive products requiring short residence times.
- Fluidized-bed dryers: Heated air passes through a perforated distributor to suspend particles, promoting relatively uniform heat and mass transfer. These systems are widely used for powders, granules, and pharmaceutical intermediates.
- Vibrating fluidized-bed dryers: Mechanical vibration assists fluidization and conveying, which can be useful for materials that are difficult to fluidize conventionally.
- Belt dryers: Material travels continuously through temperature-controlled zones on a perforated belt. Belt systems are suitable for relatively large throughputs and products requiring staged drying.
- Vacuum dryers: Reduced pressure lowers the boiling point of moisture and can support drying at lower product temperatures. This is relevant for heat-sensitive, oxidizable, or solvent-containing materials.
- Flash and pneumatic dryers: Fine, wet particles are dispersed in a fast-moving gas stream, enabling rapid drying with comparatively short residence times.
- Rotary dryers: Rotating drums provide continuous material movement and are commonly applied to robust bulk solids and materials requiring high throughput.
- Hollow-blade dryers: Heated rotating blades transfer heat to material through contact surfaces while promoting mixing and moisture removal.
- Hot-air circulation ovens and tray dryers: These systems provide batch drying through controlled circulation of heated air and are often selected for small or medium batches, laboratory development, and diversified production.
Dryer selection depends on the feed’s moisture content, viscosity, particle morphology, thermal sensitivity, solvent characteristics, desired final moisture, production rate, and cleaning requirements. In industrial practice, the thermal process is also affected by upstream filtration, concentration, atomization, conveying, and downstream separation.
Mixing and Granulation
The company’s product range includes mixers and drying granulators. Mixing equipment is used to distribute active ingredients, additives, fillers, pigments, or other components throughout a batch. Granulation systems convert powders or wet masses into more manageable particles with controlled size, density, and flow characteristics.
These functions are relevant to plastics-related production because polymer additives, colorants, fillers, and specialty powders often require uniform blending and controlled particle handling before compounding or downstream conversion.
Dust Collection and Auxiliary Systems
Dust-removal equipment supports workplace control, product recovery, and protection of downstream machinery. Auxiliary systems may include fans, heaters, air filters, cyclones, condensers, feeding devices, discharge systems, and control panels.
For plastics processors, effective dust collection is particularly important when handling powdered additives, reinforcing minerals, pigments, recycled polymer fines, and flame-retardant formulations. Equipment design must account for dust loading, static electricity, particle explosibility, and cleaning access.
Applications and End Markets
Xinggan’s equipment is used across several industrial sectors:
- Pharmaceuticals: Drying of powders and granules, preparation of pharmaceutical intermediates, and batch processing under controlled conditions
- Chemicals: Processing of inorganic salts, chemical intermediates, catalysts, pigments, and specialty compounds
- Food and agricultural products: Drying of extracts, starches, proteins, grains, fruits, vegetables, and other food or agricultural materials
- Environmental protection: Treatment and moisture reduction of sludge, residues, and recovered materials
- Textiles and electronics: Processing of chemical auxiliaries, powders, components, and moisture-sensitive materials
- Plastics and rubber: Drying of additives, pigments, polymer-related powders, and compounding ingredients
- Mineral and industrial materials: Drying and handling of mineral concentrates, fillers, and other bulk solids
The company’s relevance to plastics manufacturing is strongest where material conditioning influences extrusion stability, pellet quality, surface appearance, electrical properties, dimensional consistency, and storage performance. Moisture control is especially significant for hygroscopic engineering polymers and for formulations containing mineral fillers or reactive additives.
Global Presence and Market Position
Xinggan is based in China and supplies equipment to domestic and international industrial customers. Company profiles describe its products as being used in markets outside China, although publicly presented information does not establish a single, independently verified figure for export share or geographic revenue distribution.
Its competitive position is shaped by several factors:
- Broad coverage of batch and continuous drying technologies
- Ability to combine drying with mixing, granulation, conveying, and dust control
- Customization for different feed materials and production scales
- Access to China’s cost-competitive equipment-manufacturing ecosystem
- Experience in industries with distinct hygiene, thermal, and process-control requirements
The company competes with Chinese equipment manufacturers and international suppliers specializing in pharmaceutical, chemical, food, mineral, and polymer-processing machinery. Competition generally depends less on the nominal machine category than on validated process performance, energy consumption, material compatibility, automation, lifecycle support, and the supplier’s ability to integrate the equipment into an existing production line.
Research and Development
Xinggan describes itself as a high-technology enterprise incorporating design, manufacturing, and research and development. Its development activities are closely linked to practical process-engineering requirements rather than to the production of plastics materials themselves.
Important areas of technical development include:
- Improving heat and mass transfer efficiency
- Adapting dryers to heat-sensitive, viscous, sticky, or abrasive materials
- Controlling particle size and agglomeration during spray and fluidized-bed drying
- Reducing product residence time and thermal degradation
- Integrating drying with granulation, mixing, cooling, and dust collection
- Improving automation, temperature control, airflow management, and process repeatability
- Designing equipment for easier cleaning and maintenance
For plastics-related applications, research priorities include stable moisture reduction, prevention of material degradation, uniform additive distribution, reduction of powder loss, and compatibility with continuous compounding and extrusion lines.
Sustainability and Environmental Considerations
Drying is often one of the more energy-intensive operations in a process plant because it requires the evaporation of water or other volatile components. Equipment design therefore has direct implications for energy use, emissions, operating cost, and product yield.
Potential efficiency measures associated with Xinggan’s equipment categories include:
- Heat recovery from exhaust air
- Improved insulation of drying chambers and ducts
- Optimized airflow and temperature zoning
- Variable-speed control for fans and conveying systems
- Selection of vacuum or low-temperature drying where appropriate
- Condensation and recovery of solvents in suitable applications
- Closed-loop filtration and dust recovery
- Integration of drying and cooling steps to reduce handling and heat loss
Environmental performance depends on the complete installation, including the heat source, exhaust-treatment system, operating conditions, feed moisture, and production schedule. Drying equipment can reduce material losses and enable recovery of powders, but it may also require substantial thermal energy and careful management of airborne dust or volatile compounds.
In plastics processing, these considerations intersect with broader efforts to lower the energy intensity of compounding, increase the use of recycled materials, and improve the quality of recycled feedstocks. Recycled polymers can have variable moisture and contamination levels, making controlled pre-processing important for reliable downstream conversion.
Quality Management and Compliance
Company and commercial equipment listings associate Xinggan with ISO 9001 quality-management certification and GMP-related manufacturing or application requirements. ISO 9001 provides a framework for documented quality processes, while GMP requirements are particularly relevant to pharmaceutical and selected food-processing installations.
Depending on the application, equipment qualification may involve:
- Material certificates and traceability
- Weld inspection and surface-finish control
- Factory acceptance testing
- Temperature and airflow verification
- Cleaning and maintenance assessment
- Control-system documentation
- Hygienic design review
- Installation and operational qualification for regulated production
Specific compliance obligations vary according to the customer’s jurisdiction, product category, pressure classification, electrical environment, and use of solvents or combustible powders. Certification claims should therefore be evaluated against the particular project scope and the current certificates supplied for the relevant equipment.
Innovations and Future Outlook
Xinggan’s future development is likely to be influenced by several structural changes in process industries:
- Growing demand for energy-efficient drying and heat recovery
- Greater use of automation, sensors, and process monitoring
- Increased processing of recycled materials and secondary raw materials
- More stringent controls on dust, volatile organic compounds, and workplace exposure
- Demand for flexible equipment capable of handling multiple products
- Expansion of pharmaceutical, specialty chemical, food-ingredient, and advanced-materials manufacturing
- Greater emphasis on hygienic design, traceability, and validated processing
Digital monitoring can improve control over inlet and outlet temperatures, humidity, airflow, pressure, feed rate, and product moisture. In more advanced installations, these variables can be connected to supervisory control systems and production records, supporting predictive maintenance and more consistent product quality.
The company’s broad equipment portfolio gives it opportunities to serve customers seeking integrated systems rather than stand-alone dryers. Its longer-term competitiveness will depend on demonstrating measurable performance in energy use, throughput, product uniformity, cleaning time, reliability, and total cost of ownership.
