FAQ:
Q1: What are the unique features of the Yamato GB211C-B? A: The GB211C-B is Yamato's highly specialized Powder Granulating, Drying, and Mixing Spray Dryer. Its defining unique feature is that it serves as ''one machine with multi-purposes.'' By combining the main unit with the GF200 glass accessory, it utilizes a highly controlled fluidized bed to dry wet powders, mix materials, and granulate particles directly. Furthermore, if you purchase the GF301 spray attachment later, it can instantly be converted back into a traditional liquid spray dryer, providing massive flexibility while saving valuable laboratory space.
Q2: What are the internal size, external size, and capacity in Liters for the GB211C-B? A: The GB211C-B is an incredibly space-efficient, multi-purpose unit designed to fit into active laboratory spaces:
External Dimensions: W760 × D420 × H1350 mm.
Weight: Approx. 110 kg.
Moisture Evaporation Capacity: Max 1500 mL/h.
Q3: What are the maximum and minimum operating temperatures? A: Designed to safely granulate and dry highly sensitive powders, the temperature regulator setting range is:
Inlet Temperature Range: 0°C up to a maximum of 240°C.
Outlet Temperature Range: 0°C up to a maximum of 100°C.
Q4: What is the temperature distribution accuracy of the oven? A: To ensure powders in the fluidized bed do not burn or degrade, the GB211C-B utilizes advanced Temperature Zoning Control and multi-PID regulation to deliver a strict Temperature Adjusting Accuracy of ±1.0°C, guaranteeing incredibly stable thermal application directly to the granular bed.
Q5: How long does it take to reach the maximum temperature? A: Engineered with an optimized, high-power heater and temperature zoning control, the GB211C-B significantly reduces the temperature reaching time. It provides highly responsive, stable heat to the fluidized bed, drastically minimizing waiting times during complex granulation protocols.
Q6: What are the internal and exterior materials, and what are the advantages of the insulator? A: To ensure absolute precision during powder mixing, the fluidized bed drying chamber is constructed from premium Ultra-hard glass. The exterior is robustly built from cold-rolled steel plate finished with a specialized chemical-proofing coating. The major advantage of the ultra-hard glass structure is that it allows researchers to perfectly observe the actual fluidized bed state and spray state in real-time, which is vital for monitoring powder flowability and adjusting binder spray rates.
Q7: What applications is this oven suitable for and what are its key features? A: The GB211C-B is uniquely suited for the granulation, drying, and mixing of wet powders for pharmaceuticals, food, catalysts, fuels, detergents, and ceramics. Through granulation and spheroidization processing, it significantly enhances the flowability of powders. It is specifically designed to handle high-value samples or research-level experiments in small batches ranging from 50g to 300g.
Q8: What are the built-in safety features? A: Safety is a paramount priority for Yamato. The GB211C-B comes fully equipped with a highly responsive suite of safety mechanisms, including overheating protection at inlet and outlet temperatures, a liquid feed pump reverse function, an overcurrent and leakage protection switch, and abnormal nozzle connection detection.
Q9: What is the shelf load weight capacity? A: Because this instrument utilizes a dynamic fluidized bed rather than static wire shelves, its load capacity is defined by the volume of powder it can suspend in the air stream. The GB211C-B is expertly engineered to securely accommodate and continuously process solid granular samples within the highly precise range of 50g to 300g per batch.
Q10: Is the price affordable while maintaining Japanese quality? A: Absolutely. Yamato is fiercely dedicated to providing incredibly cost-effective laboratory solutions. Instead of forcing a facility to purchase a separate granulator, a powder mixer, and a spray dryer, the multi-purpose GB211C-B saves massive capital costs by combining these features. It is deliberately NOT priced at a premium. This gives your laboratory 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 should specifically choose the GB211C-B when your primary research goal is the granulation and mixing of wet solid powders, rather than drying pure liquid solutions. If you need to enhance the flowability of specific high-value powders (like ceramics or precious metals) in small 50g-300g batches, and you want to save space by using one modular machine for multiple thermal tasks, the GB211C-B is the perfect choice.
Q12: What standard ports and optional accessories are available? A: The GB211C-B comes standardly equipped with the GF200 glass components required for granulation, an automatic lifting function, and a 7-inch touch screen. To maximize utility, you can customize it with the GF301 Spray Attachment (to convert it back to a standard liquid spray dryer), the GAS510C Organic Solvent Recovery Unit, and data recording/remote control software.
Q13: Can these ovens be customized to suit specific customer needs? A: Yes. Recognizing that every advanced materials laboratory has distinct workflows, Yamato can customize the GB211C-B to a certain level to suit specific customer needs. Whether you require specific hardware integrations, unique remote-control setups, or specialized data output terminals for your analytical monitoring systems, Yamato’s flexible manufacturing approach ensures your fluid-bed granulator perfectly matches your facility's operational requirements.
