What are the types of spray dryers? There are still many kinds of specific calculations. There are about 8 common types. Then let us share with you the common types of spray dryers.
The first type: spray dryer for small laboratory (experimental spray dryer)
It is mainly suitable for the production of micro-particulate powder in universities, research institutes and laboratories of food, pharmaceutical and chemical enterprises. It has broad-spectrum applicability to all solutions such as emulsions and suspensions, and is suitable for drying heat-sensitive substances such as biological products and biological products. Pesticides, enzyme preparations, etc., because the materials sprayed are only exposed to high temperatures when sprayed into mist-sized particles, so they are only heated instantaneously, which can keep these active materials from being damaged after drying. Can be customized according to materials.
The second kind: low temperature spray dryer
It can realize continuous 35°C low temperature spray dryer with high recovery rate. Keep material activity. Can be customized into high and low temperature integrated spray dryer (QFN-PWGD) series of high and low temperature spray dryer can achieve 35 degrees to 220 degrees range), can be spray dried. Typical materials: low temperature equipment such as protease, camel milk, enzyme preparations, plant extracts, etc. Our company specializes in the elaboration of heat-sensitive materials, which can maintain the activity of the original materials, such as macromolecules, microorganisms, sugar-containing materials, etc.) according to user requirements Custom high-low temperature integrated machine, can be used at low temperature, high temperature test, multi-purpose integrated equipment.
The third type: high-speed centrifugal spray dryer
Electric centrifugal atomizer, centrifugal atomizing spray head, the particle size distribution of the material is steeper, and the particle distribution is more uniform; the large color touch screen operation, the combination of automatic control and manual control, Chinese and English panels, parameter LCD display.
Real-time control PID constant温度control technology, accurate temperature control, heating temperature control accuracy ± 1 ℃. Drying speed is fast, generally only 1-1.5 seconds, with instant drying characteristics. Centrifugal spray dryer; the material completes the drying process in a short time, suitable for the drying of heat-sensitive materials, and can maintain the original characteristics of the materials. The production process is simplified, the intelligent operation touch screen program control is convenient, suitable for the experimental type, continuous control production type, please contact our company staff to customize the production type spray dryer.
The product has good dispersibility, fluidity and solubility.
Fourth: spray granulation dryer
The uniform spherical mist droplets can be directly transformed into particles by uniform heat, which can be used in experiments and small-scale production. The particle balls have good precision and uniform particles. Because the device is small, it can be installed in ordinary laboratories. The core accessories are all imported equipment, and the other accessories are all produced by well-known domestic manufacturers to ensure the stability and safety of the products.
Fifth type: closed circulation spray dryer (organic solvent spray dryer)
Closed cycle spray dryer (organic solvent spray dryer)
The device is particularly aimed at organic solvents, and the inert gas medium formed by using circulating nitrogen is used to replace the normal air medium for spray drying. In addition to recovering products, organic solvents can be recovered. In view of the low flash point or slightly toxic characteristics of organic solvents, and the characteristics of flammability and explosion, the closed circulation spray system is specially designed.
Sixth type: vacuum low temperature spray dryer
It is the most effective way to quickly dry heat-sensitive materials. It realizes the instant drying of materials at low temperature (minimum 80 ℃), providing extremely convenient and safe drying methods for heat-sensitive materials, such as biological products such as enzyme preparations and live bacteria, sugar content High natural medicine extracts of traditional Chinese medicine, heat-resistant polymer materials, materials that vaporize when heated, etc.
Seventh: Superfine powder spray dryer
采用气流雾化喷雾,角度是small, and it will not hit the wall; drying achieves 1-8 micron powder with small particle size; the particle size is normal and the normal is steeper, the particles are more uniform, the particle size is adjustable, and the scope of application of the material is more Wide, the entire atomization mechanism, without any plastic gasket, without any motor, has a longer service life, easy maintenance, can be upgraded to a steel-steel coating atomization mechanism, can use a variety of metal materials, atomization mechanism disassembly and cleaning Convenient且易于维护
Eighth: pressure airflow spray dryer
It is suitable for drying heat sensitive substances such as biological products, biological pesticides, enzyme preparations, etc. Because the sprayed material is only subjected to high temperature and instantaneous heat when sprayed into a mist, these active materials maintain their active ingredients unchanged after drying.
