Spray Dryer (Large Capacity)(DL411C)

FAQ:
Q1: What are the unique features of the Yamato DL411C? A: The DL411C represents Yamato's elite, Large Capacity Type spray dryer. Its defining unique feature is its massive scale and ability to efficiently recover highly elusive 40~100μm micro-particles, which are generally considered very difficult to obtain on standard laboratory spray dryers. It features a massive drying chamber specifically designed with a special cold air inlet to effectively prevent spray particles from refluxing and adhering upwards, ensuring massive yields for production preparatory experiments.

Q2: What are the internal size, external size, and capacity in Liters for the DL411C? A: Engineered for large-scale production prep, the DL411C boasts massive dimensions:

• Moisture Evaporation Capacity: A massive Max 3000 mL/h.

• Drying Chamber Size: Internal diameter 457 × height 975 mm (glass part).

• External Dimensions: W1080 × D850 × H1770 mm.

• Weight: Approx. 180 kg.

Q3: What are the maximum and minimum operating temperatures? A: Designed to handle massive volumes of liquid and provide sufficient time for drying large fine particles, the temperature regulator setting range is expanded:

• Inlet Temperature Range: 0°C up to a maximum of 300°C.

• Outlet Temperature Range: 0°C up to a maximum of 100°C.

Q4: What is the temperature distribution accuracy of the oven? A: Even at a massive 3000mL/h throughput and 300°C high heat, the DL411C utilizes an advanced multi-PID system to deliver elite thermal regulation. It provides a strict Temperature Adjusting Accuracy of ±1.0°C, ensuring that highly sensitive samples receive absolutely perfectly distributed radiant heat as they fall through the massive chamber.

Q5: How long does it take to reach the maximum temperature? A: Engineered with optimized, dual high-power 2.0kW × 2 heaters and temperature zoning control, the DL411C drastically reduces temperature reaching times. It guarantees instantaneous heating to the massive volume of sprayed droplets, easily maintaining its extreme 300°C inlet temperatures even under heavy continuous liquid loads.

Q6: What are the internal and exterior materials, and what are the advantages of the insulator? A: To ensure absolute zero contamination during massive powder yields, the massive drying chamber, cyclone unit, and product container are constructed from premium Ultra-hard glass. All other internal piping materials are strictly stainless steel and silicone. The major advantage of the ultra-hard glass structure at this massive scale is that it allows researchers to completely visually verify the spray status of large-batch runs, ensuring zero blockages or refluxing without needing to halt production.

Q7: What applications is this oven suitable for and what are its key features? A: The DL411C is the ultimate instrument for production preparatory experiments, high-value sample experiments, and capsule spray drying method application research. Because it can produce industry-standard 40~100μm particles, it serves as the perfect bridge instrument between small-scale lab R&D and massive industrial factory production in the ceramics, food, organic chemistry, and pharmaceutical sectors.

Q8: What are the built-in safety features? A: Safety is a paramount priority for Yamato, especially when operating massive 1770mm tall fluid vessels at 300°C. The DL411C is equipped with a highly comprehensive suite of safety mechanisms, including inlet and outlet temperature overheating protection, a liquid delivery pump reverse function, an overcurrent leakage protection switch, and importantly, an independent overheating preventer for the outside of the heater.

Q9: What is the shelf load weight capacity? A: Because this is an active, large-capacity Spray Dryer and not a static heating oven, it does not utilize traditional wire shelves for load bearing. Instead, its ''load capacity'' is defined by its massive fluid processing power. It features a highly efficient liquid feed pump (adjustable from 0 to 70 mL/min) that provides a massive maximum moisture evaporation capacity of 3000 mL/h alongside a massive drying air volume of 0.13~1.0 m³/min, allowing it to continuously process industrial-scale liquid volumes.

Q10: Is the price affordable while maintaining Japanese quality? A: Absolutely. Yamato is fiercely dedicated to providing incredibly cost-effective laboratory solutions. Even with its massive 3000mL/h capacity, ability to generate 100μm micro-particles, and elite 7-inch touch-screen architecture, the DL411C is deliberately NOT priced at a premium. This gives your facility direct access to an elite standard of Japanese manufacturing without breaking the budget. You receive an instrument built with over 130 years of Yamato’s strict quality control, rigorous testing, and rich engineering heritage.

Q11: When and why should we use this oven? A: You MUST choose the DL411C when standard lab spray dryers (which typically produce particles under 20μm) cannot meet your size requirements. If you are preparing for industrial production and specifically need to test yields of 40~100μm particles (common in ceramics and pharmaceuticals), or if your facility needs to continuously evaporate massive 3000mL/h batches, the DL411C is the definitive, uncompromised choice.

Q12: What standard ports and optional accessories are available? A: The DL411C comes standardly equipped with a 7-inch touch screen, a service socket for a stirrer (200-230V~1A), and an exhaust connection (Φ50mm). To maximize utility, you can customize the unit with an optional three-fluid nozzle system, the GAS510C Organic Solvent Recovery Unit (for flammable solvents), and external data recording/remote control software modules.

Q13: Can these ovens be customized to suit specific customer needs? A: Yes. Recognizing that every production preparatory facility has distinct workflows, Yamato can customize the DL411C to a certain level to suit specific customer needs. Whether you require specific 3-fluid nozzle integrations, unique hardware setups to handle aggressive solvents, or specialized centralized monitoring integrations for your production line, Yamato’s flexible manufacturing approach ensures your large-capacity spray dryer perfectly matches your operational requirements.
