China Jiangsu Shengman Drying Equipment Engineering Co., Ltd Company News

We attend the IE expo China 2015 from Apr 21st -23rd. Our hollow blade dryer attracts many customers. 

Welcome to visit our company. The man is quite interested in our spray drying machine. 

We attend the fair and show our hot product spray drying machine. 

Here are some key points to consider when discussing or designing a spray dryer: 1. Inlet Temperature: The temperature of the air entering the spray dryer affects the drying rate and the final product quality. Typically, it ranges from 150°C to 250°C, depending on the product being dried. 2. Outlet Temperature: The outlet temperature (air leaving the dryer) should be carefully controlled to avoid over-drying or burning the product. It usually ranges from 60°C to 100°C. 3. Feed Characteristics: The feed’s temperature, viscosity, solids content, and particle size are critical for determining the dryer’s efficiency and the quality of the end product. 4. Atomization Method: The method of atomizing the feed into fine droplets plays a significant role in the drying efficiency. Common methods include pressure nozzles, rotary atomizers, and twin-fluid nozzles. 5. Airflow Configuration: Co-current flow: The hot air and product travel in the same direction, which results in a higher outlet temperature and is suitable for heat-sensitive materials. Counter-current flow: The hot air and product travel in opposite directions, providing more efficient drying but often leading to a lower outlet temperature. Mixed flow: A combination of co-current and counter-current airflow, balancing the pros and cons of both. 6. Drying Time: The time the droplets spend in the drying chamber should be sufficient for drying but not so long that it causes product degradation. This is influenced by air temperature, airflow rate, and droplet size. 7. Particle Size: The particle size of the dried product can vary depending on the atomization technique and drying conditions. Smaller particles generally lead to quicker drying times but might need finer control of the drying parameters. 8. Residence Time: The residence time of droplets in the dryer should be optimized to ensure that the particles are adequately dried without excessive heat exposure. 9. Cyclone Separator: The cyclone separator is often used to collect fine particles from the exhaust air, separating them from the exhaust stream before discharge. 10. Moisture Content: The desired final moisture content of the dried product is a critical factor. Usually, spray dryers target a final moisture content of 2-5%, depending on the product. 11. Energy Efficiency: Spray dryers can be energy-intensive, so efficient heat recovery systems and optimal air handling (e.g., using waste heat) can improve overall energy efficiency. 12. Product Quality: Factors such as particle size distribution, color, and solubility are important product quality indicators. These can be influenced by drying conditions like inlet temperature, feed rate, and atomization method. 13. Feed Pump: The feed pump must be capable of delivering a consistent flow of slurry or liquid to the atomizer to ensure uniform drying. 14. Scale-Up Considerations: When scaling up from lab-scale to industrial-scale spray drying, factors such as heat transfer, atomization, and particle behavior should be thoroughly tested. 15. Cleaning and Maintenance: Regular cleaning of the spray dryer (especially the atomizer, cyclone separator, and chamber) is essential to prevent build-up and ensure consistent product quality. 16. Automation and Control Systems: Modern spray dryers often come with sophisticated control systems for monitoring and adjusting parameters like temperature, humidity, and airflow in real time for optimal performance. 17. Safety Considerations: Proper safety measures should be in place, including explosion protection (especially when drying flammable or combustible materials) and adequate ventilation to handle the exhaust.

Cost Efficiency Over 40% of factories prioritize our spray dryer for its proven 30-40% reduction in operational costs. By optimizing energy consumption (e.g., steam usage as low as 1,600kg/h per 500kg water evaporation) and minimizing heat loss in tropical climates, it delivers the lowest drying cost per ton in Southeast Asia – a critical factor for price-sensitive markets。   Technical Adaptability With humidity-control technology specifically engineered for Southeast Asia's high-temperature environments, our system maintains stable drying efficiency (inlet air: 160-165°C, outlet: 75°C) even at 85% ambient humidity. This eliminates powder caking – a top pain point for 72% of regional manufacturers.        

The powder spray dryer excels in reducing energy consumption while preserving nutrition. Its key feature is ultra-fast drying, where droplets remain in hot air for only a few seconds, minimizing energy use and preventing nutrient loss from prolonged heating. Equipped with high-efficiency heating and air filtration systems, it ensures clean hot air and optimal energy utilization, achieving average energy savings of over 30%. For producers of health foods and functional beverages, this drying method maintains protein, vitamin, and flavor integrity while cutting operating costs, making it vital for market competitiveness.

The powder making machine is highly competitive in export markets due to its quality certification and adaptability. Certified under ISO9001 and CE standards, it meets international entry requirements. Whether in Southeast Asia, South America, or Africa, customers can purchase and operate it with confidence. In terms of design, the equipment supports modular customization and allows flexible heating methods (electric, steam, gas, or oil) to suit local energy conditions. The manufacturer also provides remote technical support and overseas engineer services, addressing the biggest concern of export clients—after-sales service. With its efficiency, low energy consumption, and premium powder output, this dryer has become a preferred choice for international buyers in dairy and food processing industries.

The spray dryer is widely used in the food industry, with its key advantage being the ultra-fast conversion of liquid into powder. The high-speed centrifugal atomizer sprays coconut milk into fine droplets of 40-120 microns, where 95% of the water evaporates instantly in hot air, completing the drying process within seconds. This ensures excellent solubility and stability while preserving proteins, vitamins, and natural flavors in the coconut milk. To further enhance quality, the drying chamber is made of SUS304 stainless steel with mirror polishing and equipped with a pulse air hammer system to prevent powder sticking and accumulation, achieving a powder recovery rate ≥95%. The PLC control system precisely monitors inlet (140-350℃) and outlet (80-90℃) temperatures, ensuring batch-to-batch consistency. For customers, this results in uniform solubility, anti-caking storage stability, and strong competitiveness in the beverage powder market.

When purchasing the spray dryer machine, food companies typically focus on three main factors: drying efficiency, energy consumption, and powder quality. First, the dryer completes drying within seconds, offering much higher productivity than traditional methods. Second, with multiple heating options (electric, steam, gas, or oil), companies can select the most economical solution based on local energy availability, cutting energy consumption by over 30%. In terms of powder quality, the machine ensures uniform particle distribution (40-120 microns), excellent solubility, and a recovery rate of ≥95%. These features directly impact product competitiveness and customer acceptance. For food enterprises pursuing large-scale production, this equipment is not just a machine but a guarantee of consistency and brand reputation.
