The low-temperature spray dryer uses a unique DACTS dry air system to achieve efficient drying of materials under low-temperature conditions (for example, the inlet air temperature can be as low as 35°C) by converting air into a solvent-carrying medium. This technology can effectively protect the active ingredients and physical properties of heat-sensitive materials, and is suitable for all types of materials that are sensitive to temperature.

Low temperature spray drying system
Applicable solvent: water
Processing capacity: The equipment can be customized from 50ml to 100L/H, and multiple units can be connected in parallel.
Temperature range: 35℃-200℃ (high and low temperature integrated design, one device can support two, and can also be used for dry heat sterilization)

Main advantages:
①The inlet air is 35°C and the outlet air is around 25°C. The material is always in a low temperature state and perfectly maintains activity.
②Continuous feeding and continuous discharging, the efficiency is about 10 times that of the freeze dryer
③High and low temperature integrated, one machine with multiple uses
④Dry instantly (1-2 seconds)
⑤ Save energy consumption. The unit output saves about 20 times more energy than the freeze dryer.

Application areas

Pharmaceutical industry?: Drying of heat-sensitive materials such as peptides, antibiotics, vaccines, and traditional Chinese medicine extracts.

Biotechnology?: Processing of active substances such as cell cultures and enzyme preparations.

Food industry?: production of dairy products, probiotic powder, fruit and vegetable powder, etc.

Chemical industry?: nanomaterials, catalysts and other fine chemical products.

Working principle of low temperature spray dryer:

Function of dry air system?:
This system converts air into a solvent-carrying medium, and through a specially designed air flow path, the air can efficiently carry solvent molecules (moisture or other volatile components) away from the material under low temperature conditions (for example, the inlet air temperature can be as low as 35°C).
Low temperature drying process?:
The liquid material is dispersed into micron-sized droplets through the atomization device to increase the surface area.
The low-temperature hot air and atomized droplets are fully contacted in the drying chamber, the solvent evaporates quickly, and the material is always in a low-temperature environment.
The dried particles are collected through a separation system, and the waste gas is discharged after treatment.
