Overview of small spray dryer machine 

The SDG-2L Laboratory Spray Dryer represents the culmination of our company's meticulous development efforts in this field. The unit features a compact, self-contained design that requires no external auxiliary facilities to operate. It is controlled via a large, full-color LCD touchscreen interface; the outer casing is high-grade SS304, and the drying chamber and cyclone separator are made of quartz glass. The system utilizes fully sealed clamp connections and is equipped with a dedicated intelligent control system, as well as a three-stage adjustable heating system. This configuration provides a broader range of thermal power coverage, enabling the unit to effectively handle the spray drying requirements of the vast majority of materials.

Working principle：

Spray dryers are primarily used to transform solutions, emulsions, suspensions, and paste-like materials into dry powders via spray drying. They offer numerous advantages, including rapid drying speeds, high efficiency, and a streamlined processing workflow. For heat-sensitive materials, the process effectively preserves their original color, aroma, and flavor; furthermore, the resulting dry powders exhibit excellent solubility and high purity. This series of spray dryers is widely applicable across various sectors, including chemical engineering, petrochemicals, light industry, food processing, pharmaceuticals, building materials, ceramics, and forest chemical industries.

Heated air enters the drying chamber after passing through a heater. Simultaneously, the liquid feedstock is atomized by an atomizer into micron-sized droplets. Upon contact with the hot air, these droplets rapidly vaporize and dry, transforming into a powder or granular product. The dried powder or granules are then carried by the airflow into a cyclone separator for separation, where they settle into a collection bottle; finally, the exhaust gas is discharged.

Application:

The laboratory spray dryer is designed for use in universities, research institutes, and the laboratories of food, pharmaceutical, and chemical enterprises for the production of small-scale particulate powders. It offers broad applicability across a wide range of liquid formulations—including emulsions and suspensions—and is particularly well-suited for drying heat-sensitive substances, such as biological products, biopesticides, and enzyme preparations. Because the sprayed material is exposed to high temperatures only during the brief, instantaneous moment it exists in an atomized state, these active substances retain their original biological activity and integrity after drying.

Specifically, this equipment is utilized in the following fields: beverages, flavorings, and pigments; milk and egg products; plant and vegetable extracts; pharmaceutical synthesis; heat-sensitive materials; plastics, polymers, and resins; fragrances; blood products; ceramics and superconductors; biochemical products; dyes; soaps and detergents; food additives; oxides; bone meal; dental powders; and many others.

Advantages:

1. It is made of high-quality 304 stainless steel, the unit features a dual-stage heating system that rapidly reaches the set temperature within one minute, enabling faster experiment initiation. It demonstrates excellent long-term heating stability, compared to other spray dryers currently on the market, yields a product powder with a significantly lower moisture content.

2. The atomizing nozzle utilizes a concentric design with adjustable particle size, ensuring continuous and uniform atomization throughout the experiment while preventing material from adhering to the chamber walls.

3. Equipped with a built-in bilingual (Chinese/English) interface, the system offers an intuitive human-machine interaction experience that eliminates the need for frequent switching during experiments; furthermore, experimental parameters can be saved for convenient recall and reuse.

4. All pipeline connection points are sealed using silicone gaskets secured by full-circumference clamps, ensuring a completely leak-free operation.

5.Prior to shipment, every unit undergoes a rigorous series of quality control tests to guarantee long-term operational stability and reliability for the customer.
