Why Choose Spray Drying? Key Benefits for Your Process
From Liquid to Powder in Seconds: Achieve instantaneous drying (5-15 seconds) with minimal thermal exposure, perfect for heat-sensitive APIs, probiotics, and food flavors.
Precision Particle Engineering: Control key powder properties—particle size, density, morphology, and moisture content—to optimize flowability, dissolution, and final product performance.
Process Simplification & Scalability: Eliminate multiple batch steps (evaporation, grinding, mixing). Our systems offer seamless scaling from lab trials to continuous production.
GMP-Centric Design: With 316L stainless steel contact parts, clean-in-place (CIP) options, and validation support, our dryers are built for regulated industries.

FAQ
-
What materials are suitable for spray drying?
Ideal for a wide range: Pharmaceutical (antibiotic extracts, vitamin preparations), Food (milk/egg powder, coffee extracts), Chemical (catalysts, ceramics). The key is pumpable liquid form.
-
How is particle size controlled in a spray dryer?
Primarily through atomization. Our LTPG series uses a centrifugal atomizer where wheel speed and feed rate precisely determine droplet size, which directly defines final powder particle size.
-
Can spray drying handle organic solvents?
Yes, with a closed-loop system and inert gas (like N₂) circulation. This is crucial for pharmaceutical processing and flammable solvents. Discuss your solvent with our engineers.
-
How long does it take to turn milk into powder using a centrifugal spray dryer?
The duration depends on the machine model. For example, the LPG-100 model takes approximately 1 hour per batch. Other models may have different processing times based on their capacity and specifications.
-
What are the differences between a pressure spray dryer and a centrifugal spray dryer?
The key differences are based on the type of material and production requirements:
For emulsified and homogenized materials containing oil, a pressure spray dryer is more suitable, as it handles higher production volumes. For example, the smallest HaiJiang machine has a water evaporation capacity of 50kg per hour, but it is more expensive.
For oil-free materials, a centrifugal spray dryer is preferred, especially for lower production volumes. For example, the LPG-5 model has a water evaporation capacity of 5kg per hour and is more affordable. -
What are the heating methods for a pressure spray dryer, and is electric heating suitable for the smallest model?
There are three heating methods: electric heating, thermal oil heating, and steam heating. For the smallest model, electric heating is recommended due to its efficiency and suitability for lower production capacities.
-
How much milk powder can the LPG-5 spray dryer produce in one day if the material is milk?
Given that milk has an 85% water content, the LPG-5 spray dryer can produce approximately 0.9 kg of milk powder per hour. Over a 24-hour period, this translates to around 21.6 kg of milk powder, depending on continuous operation conditions.
