It is widely used for applications in industries like food processing, pharmaceuticals, chemicals, and biotechnology. Below are the key specifications for the APV Anhydro Spray Dryer Compact EL (MicroSpray):

Key Specifications of the APV Anhydro Spray Dryer Compact EL, MicroSpray

1. Design and Size

• Compact and Modular: The MicroSpray is designed to be space-efficient with a small footprint, ideal for laboratory and small-scale production environments.
• Space Requirements: Compact enough to be installed in laboratory spaces or small production areas.
• Material Contact Parts: Typically constructed of stainless steel (AISI 316L) for corrosion resistance and ease of cleaning.

2. Atomization System

• Atomizer Type: High-performance atomization through a rotary atomizer or pressure nozzle.
  • The rotary atomizer uses centrifugal force to break up the liquid feed into fine droplets.
  • Pressure nozzles can also be used, depending on the feed material and application.
• Droplet Size: The atomization process ensures uniform droplet size, which directly affects particle size distribution in the final powder.

3. Drying Process

• Inlet Temperature: Typically adjustable from 150°C to 250°C depending on the application and product sensitivity.
• Outlet Temperature: Adjustable based on the process conditions but typically ranges from 80°C to 120°C.
• Feed Rate: Adjustable, depending on the material and required output. Typical feed rates are in the range of 0.5 to 5 L/h, though this can vary based on atomization method and inlet temperature.

4. Airflow and Drying Capacity

• Airflow Capacity: Designed to handle moderate airflow rates suitable for small batches.
• Drying Capacity: While specific capacities can vary depending on the setup and feed characteristics, the MicroSpray is ideal for small to medium-scale pilot applications with drying capacities typically in the range of 0.5 to 3 kg/h of dried product, depending on the material being processed.

5. Particle Size Control

• Particle Size Distribution: The system allows control over particle size by adjusting key process parameters such as feed rate, atomization pressure, inlet temperature, and airflow. This is critical in industries where uniformity of powder is important, such as pharmaceuticals and food.

6. Powder Recovery System

• Cyclone Separator: Includes an integrated cyclone separator for efficient powder recovery from the exhaust air.
• Bag Filter Option: Some versions may include a bag filter or other fine powder collection systems to capture ultra-fine powders.

7. Control and Monitoring

• Digital Control Panel: The system features an intuitive control panel that allows easy setting and monitoring of process parameters such as:
  • Air temperature (inlet and outlet)
  • Feed rate
  • Atomization pressure
  • Airflow
• Automated Process Control: Advanced models may include automated feedback systems to continuously adjust parameters for optimal drying conditions.
• Data Logging: Some systems may have options for logging process data for quality control and traceability.

8. Material Feed System

• Liquid Feed Type: Suitable for a wide range of feed types, including solutions, suspensions, and emulsions.
• Feed Pump: Typically uses peristaltic pumps or gear pumps to control the flow rate of the feed material.

9. Energy Efficiency

• Low Energy Consumption: Designed to be energy-efficient, especially for small-scale or research applications.
• Heat Recovery Options: Features like heat recovery can be integrated into the system to improve energy efficiency by reusing some of the hot air.

10. Safety and Environmental Features

• Explosion-Proof Design: For some processes, explosion-proof or inert gas options may be available for safety when working with flammable materials.
• Dust Collection: The recovery system ensures efficient collection of fine powders to reduce product loss and minimize airborne particles.
• Material Handling: The system is designed with ease of cleaning and maintenance in mind, ensuring that cross-contamination is minimized and cleaning procedures are straightforward.

11. Applications

• Pharmaceuticals: Drying of active pharmaceutical ingredients (APIs), excipients, and other formulations for tablet production, encapsulation, or powder formulations.
• Food and Beverages: Production of powdered products like milk powder, fruit powders, flavorings, and instant coffee.
• Chemicals: Drying fine chemicals, pigments, or detergents, particularly when precise particle size control is required.
• Biotechnology: Drying of enzymes, probiotics, and other bio-based products in a way that preserves their activity and efficacy.

Benefits of the APV Anhydro Spray Dryer Compact EL, MicroSpray:

• High-Quality Product: Produces uniform, high-quality powders with a consistent particle size, making it ideal for pharmaceutical, food, and chemical applications.
• Versatile Applications: Suitable for a wide range of applications, from R&D to pilot-scale production.
• Compact and Easy to Operate: Small footprint and user-friendly controls make it perfect for laboratories and small-scale production.
• Scalable: Can be used in pilot plants for small-scale batches, and the process can be scaled up with minimal changes to the drying parameters.

Conclusion:

The APV Anhydro Spray Dryer Compact EL (MicroSpray) is an excellent choice for small-scale and laboratory applications, offering flexibility, precise control over drying parameters, and efficient operation. It is particularly well-suited for industries such as pharmaceuticals, food processing, chemicals, and biotechnology, where high-quality, consistent powders are required, and space is at a premium.
