High Efficiency Pilot Centrifugal Spray Dryer 6l/h

Brief Introduction Of our Pilot centrifugal spray dryer

SD-6L centrifugal spray dryer is constructed from high-quality and food-grade SS304 and features a precision-finished surface treatment. It is operated via a 10-inch high-definition touchscreen interface, integrated with a dedicated intelligent control system and a high-efficiency spiral cyclone separator. This configuration ensures excellent drying performance and a high material recovery rate during pilot-scale trials.

Working principle and advantages of our Pilot centrifugal spray dryer

The filtered air enters an air heater, Once heated to a specified temperature, the air enters a hot air distributor tangentially. Conditioned by the distributor, the air flows uniformly and spirally into the drying chamber. 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 carried along with the airflow into a cyclone separator for separation; finally, the exhaust gas is discharged through the fan outlet or directed into a dust collector before being expelled.

The centrifugal spray dryer employs a co-current spray drying method, wherein the liquid droplets flow in the same direction as the hot air. Although the hot air temperature is high, the drying material is prevented from overheating because the hot air comes into immediate contact with the sprayed droplets the moment it enters the drying chamber, while the simultaneous evaporation of the droplets absorbs heat. Furthermore, the airflow path within the piping has been optimized and paired with a high-efficiency cyclone separator, enabling a material recovery rate of over 94% for certain materials. The entire body of the equipment-including the internal piping and all components that come into contact with the material-is constructed from SUS304 stainless steel, thereby guaranteeing that the product remains free from contamination.

Application Of our Pilot centrifugal spray dryer

It suitable for the production of trace particulate powders in laboratories of universities, research institutes, and food, pharmaceutical, and chemical enterprises. It has broad applicability to all solutions, such as emulsions and suspensions, and is suitable for drying heat-sensitive materials such as biological products, biopesticides, and enzyme preparations. Because the sprayed material is only exposed to high temperatures and instantaneously when atomized, these active materials retain their active components after drying.

Common application fields:
   Beverage flavorings and colorings
   Milk and egg products, plant and vegetable extracts
   Pharmaceutical synthesis of heat-sensitive substance
   Plastic polymers and resins, aromatants
   Blood products
   Ceramics and superconductors
   Biochemical products, dyes
   Soaps and detergents
   Food adhesives, oxides, bone meal and tooth powder, etc.

Why Choose Our our Pilot centrifugal spray dryer?

.Precision Control: These units usually feature PLC touchscreens to monitor inlet temperature (often up to 250°C or higher) and outlet temperature.

.Material Integrity: Because the evaporation is so fast, the core of the droplet stays relatively cool. This makes it perfect for heat-sensitive materials like enzymes, proteins, or herbal extracts that would otherwise degrade.

.Uniformity: The centrifugal disc produces a very consistent particle size compared to pressure nozzles, which is critical for "flowability" in powders.

.Compact Footprint: Unlike industrial towers that stand stories high, a 5L/h unit is typically a "plug-and-play" machine that fits in a standard laboratory or cleanroom.
