Shanghai Haozhuang Instrument Co., Ltd. has developed a small spray dryer of the brand Hao Zhuang (LNB), which is energy-saving and environmentally friendly, leading the country. Affordable quality assurance!
Spray drying has the characteristics of fast heat transfer, rapid evaporation of water, instant drying time, good product quality and good dissolution performance, which can improve the dissolution rate of certain formulations. In addition, spray drying can also be used to prepare microcapsules.
"Workers want to do their best, must first sharpen their tools", according to the physical or chemical properties of different materials, as well as the size and solubility of the powder or granules required by the experiment, researchers may need to type laboratory spray Only the dryer can get the best experimental effect. Shanghai Haozhuang Instrument Co., Ltd. Haozhuang (LNB) brand small spray dryer-spray drying is a method of systematic technology applied to material drying. After the liquid material is atomized in the drying chamber, it is in contact with hot air In the process, the water vaporizes instantly to obtain a dry product. This method can directly dry the solution and emulsion into a powder or granular product, which can save the steps of evaporation and crushing, and the particles are evenly distributed.
1) The sugar content is relatively high (if juice, Chinese herbal medicine or natural product extracts) or heat-sensitive materials because most polysaccharide disaccharides have a low melting point. When heated, the sugar melts, and the polysaccharide disaccharide itself is easier It absorbs moisture, so the ordinary spray dryer will easily stick to the wall, and it is not easy to get good dry powder or particles. In addition, like enzyme preparations, live bacteria, and some polymer materials that are more easily denatured at high temperatures, using ordinary spray dryers, the materials are very susceptible to inactivation or denaturation. Temperature, you can get better experimental results, Shanghai Haozhuang Instrument Co., Ltd. L-6000Y laboratory spray dryer and L-6000 laboratory low temperature spray dryer can be tested at a relatively low inlet air temperature, for example, L -The inlet air temperature of 6000Y laboratory spray dryer can be set to 110 ℃. Generally, the materials with high sugar content can get better particles. The sugar content of some materials may have a lower melting point, and the L-6000 laboratory low temperature spray dryer can complete the spray dryer process at an inlet air temperature of 60-80 ° C, such as enzyme preparations, live bacteria, etc. The temperature is instantaneous and the activity is not affected at all.
2) The solvent is an organic solvent or an easily oxidized material. The organic solvent is difficult to dry in spray drying. Generally, the organic solvent will be flammable and explosive. The explosion-proof closed laboratory spray dryer allows the material to be sealed The drying system is circulated, and the entire system is filled with inert gas (such as nitrogen or argon), which can avoid the contact between the organic solvent gas and the external oxygen air, ensuring safe production. Shanghai Haozhuang L-6000Y experimental organic solvent spray dryer uses a safe nitrogen (or other inert gas) closed circulation method, the entire system is fully closed, and the oxygen concentration is monitored online. Once the oxygen concentration in the system reaches 1.5% , The system will automatically shut down and alarm. It is a small spray dryer for laboratory organic solvents with good safety and easy operation. It can be used for flammable and toxic solvents through the use of nitrogen closed circulation and complete solvent recovery. It can be processed and can be easily dried. Moreover, since the boiling point of the organic solvent is low, it is possible to dry materials that are easily thermally denatured by low temperature drying.
3) Materials that need to obtain large particles of powder In some experimental processes, scientific researchers hope to obtain some samples of large particles, such as the catalyst industry, generally require particles of about 100 microns to have better catalytic effect, but ordinary spray dryers Only particles below 30 microns can be obtained. The L-6000 laboratory spray drying granulator can better achieve the experimental purpose. The L-6000 spray granulator can be used as a separate spray dryer to obtain particles of about 100 microns, and it can also achieve the granulation of small particle powders and can obtain large particles above 100 microns.
4) Materials with extremely poor heat sensitivity or requiring improved solubility. Some materials cannot be heated. The traditional freeze-drying time is very long, and the dried materials are lumpy, with poor fluidity and poor solubility. Compared with the traditional freeze-drying technology, the L-6000Y laboratory spray freeze dryer has the following advantages: (1) The atomized and dispersed small droplets are immersed in low temperature to freeze quickly, which can weaken the growth of ice crystals and reduce the lipid of ice crystals. The destruction of the body to avoid drug leakage and burst release; (2) The frozen sample was dried in vacuum to form spherical particles with a microporous structure, good fluidity, and the size of the particles can be adjusted by changing the spray process. L-6000Y laboratory spray freeze dryer is suitable for low temperature drying of heat sensitive, viscous, active materials and high sugar content materials, such as Chinese herbal medicine natural product extracts, dairy products, biological preparations, enzyme preparations, fruit juice , Polymer materials, etc.
5) Conventional materials Some laboratories are used for the preparation of conventional powders or the drying of materials. You can choose Haozhuang L series laboratory spray dryer, which is small in size, fast in speed, low in noise, easy to operate, and 20ML material can be completed In one experiment, the dried powder had good sphericity, and the particle size was distributed too positively. Especially, the machine has a spray head water cooling device and tower wall purge function, which greatly expanded the application of laboratory spray dryer.
