Spray-Dryer

Spray Dryer

spray dryer Equipment in which the material to be dried is sprayed as a fine mist into a hot‐air chamber and falls to the bottom as dry powder. The period of heating is very brief and so nutritional and functional damage are avoided. Dried powder consists of hollow particles of low density; widely applied to many foods (e.g. milk) and

Product description

A spray dryer takes a liquid stream and separates the solute or suspension as a solid and the solvent into a vapor. The solid is usually collected in a drum or cyclone. The liquid input stream is sprayed through a nozzle into a hot vapor stream and vaporized. Solids form as moisture quickly leaves the droplets. A nozzle is usually used to make the droplets as small as possible, maximizing heat transfer and the rate of water vaporization. Droplet sizes can range from 20 to 180 μm depending on the nozzle.[3] There are two main types of nozzles: high pressure single fluid nozzle (50 to 300 bars) and two-fluid nozzles: one fluid is the liquid to dry and the second is compressed gas (generally air at 1 to 7 bars).
Spray-Dryer

Spray dryers can dry a product very quickly compared to other methods of drying. They also turn a solution (or slurry) into a dried powder in a single step, which simplifies the process and improves profit margins.

In pharmaceutical manufacturing, spray drying is employed to manufacture Amorphous Solid Dispensation, by uniformly dispersing Active Pharmaceutical Ingredients into a polymer matrix. This state will put the active compounds (drug) in a higher state of energy which in turn facilitates diffusion of drug spices in patient body.

Features of  Spray dryer

  • Dedicated to laboratory research, complete a test with a minimum of 20-30ml of liquid.
  • Full borosilicate glass for easy and intuitive monitoring of process status.
  • Spray chamber, cyclone separator and receiving box are made of borosilicate glass, which can resist strong acid / strong alkali and high temperature.It can work in a pollution-free and stable environment.
  • easy to clean, assembly and disassembly are very simple.
  • The air compressor is oil-free and does not pollute the compressed air. The sound is below 50db.
  • Inlet and outlet temperature is precisely controlled by PID.
  • The device is self-sufficient, no supporting equipment is required, and it can be used immediately.
  • Touch screen face display operation is used to control temperature, air volume, air pressure, pump speed and frequency of deblocker.
  • The product adopts rotary pump to feed, the capacity is adjustable.
  • Automatic clogging device prevents nozzle clogging and variable control.

Application of Spray dryer

Spray dryer is mainly suitable for universities, research institutes, food, pharmaceutical and chemical enterprises, laboratories, etc.It can produce trace granular powders, and has a wide applicability to all solutions such as emulsions and suspensions.Suitable for drying heat-sensitive substances, such as biological products, biological pesticides, enzyme preparations, etc.Because the sprayed material is exposed to high temperature only when sprayed into mist-like particles, it is only heated instantaneously, which can keep these active materials from drying after the active ingredients are not damaged.

Spray dryer is suitable for various fields that need to produce free powder. The applicable fields include:Beverages, flavors and colors, milk and egg products, plant and vegetable extracts, pharmaceuticals, synthetic materials, heat-sensitive materials, plastic polymers and resins, perfumes, blood, ceramic and superconductor biochemicals, dyes, soaps and detergents, food , Adhesives, oxides, textiles, bones, teeth, etc.
