"Workers must first sharpen their tools if they want to do something good." Scientists may need different types of laboratory sprays for the physical or chemical properties of different materials, as well as the size and solubility of the powder or particles that the experiment requires. Dryer, in order to get the best experimental results.

Spray drying is a drying method for rapidly drying liquid materials. After the liquid material is atomized in the drying chamber, the moisture is instantaneously vaporized in contact with hot air to obtain a dried product, which can directly make the solution and the milk. The turbid liquid is dried into a powdery or granular product, which can eliminate the steps of evaporation, concentration, pulverization, etc., and the obtained particles are evenly distributed. The spray drying has the characteristics of fast heat transfer, rapid evaporation of water, instant drying time, and good product quality. , solubility properties are also good, can improve the dissolution rate of some formulations, in addition, spray drying can also be used to prepare microcapsules.

If it is high in sugar (if juice, Chinese herbal medicine or natural product extract) or heat sensitive material (such as enzyme preparation live bacteria, etc.), because most polysaccharide disaccharides have a lower melting point, when heated, sugar occurs. Melting, and the polysaccharide disaccharide itself is relatively easy to absorb moisture, so the ordinary spray dryer will easily appear sticky wall phenomenon, it is not easy to get good dry powder or granules. In addition, like enzyme preparations, live bacteria and some at high temperatures In the case of polymer materials that are more susceptible to denaturation, the material is easily deactivated or denatured by using a common spray dryer. At this time, by reducing the inlet and outlet temperatures of the spray dryer, a better experimental result can be obtained. Room spray dryers and laboratory low temperature spray dryers can be tested at relatively low inlet air temperatures. For example, the inlet air temperature of the YMANLAB-W2L-304P laboratory spray dryer can be set to 110, which is generally high in sugar content. The materials can get better particles. Some materials have lower sugar content and may have lower melting point. YMANLAB-W2L-304P laboratory low temperature spray dryer combines the advantages of spray drying and vacuum drying in 60-80. Enter At the temperature of the wind, the spray drying process, such as enzyme preparations, live bacteria, etc., can be instantaneously dried at such low temperatures, and the activity is completely unaffected.

Furthermore, the solvent is an organic solvent or an easily oxidizable material. In the spray drying, the solvent of the organic solvent is difficult to dry. Generally, the organic solvent is inflammable and explosive. The explosion-proof closed laboratory spray dryer enables the material to be Circulating in a closed drying system, the whole system is filled with inert gas (such as nitrogen or argon), which can avoid the contact of organic solvent gas with external oxygen, ensuring safe production. YMANLAB-W5L-304S experimental organic solvent spray dryer adopts The safety of nitrogen (or other inert gas) closed circulation mode, the whole system is closed, the oxygen concentration is monitored online, once the oxygen concentration in the system reaches 2%, the system will automatically stop and alarm, it is safe. The small-sized spray dryer for laboratory organic solvents, which is easy to operate, can be used to treat flammable and toxic solvents by using a closed nitrogen circulation method and a complete solvent recovery method, and can perform drying of easily oxidizable substances. Since the boiling point of the organic solvent is low, it is possible to dry the material which is susceptible to heat denaturation by means of low temperature drying.

In some experiments, researchers hope to get some samples of large particles, such as the catalyst industry, generally need about 100 microns of particles to have better catalytic effect, but ordinary spray dryer can only get particles below 30 microns. , MANLAB-W2L-304P laboratory spray drying granulator, can be better to achieve the purpose of the experiment. MANLAB-W2L-304P spray granulator, can be used as a separate spray dryer to get about 100 microns of particles, It can also realize the granulation of small particle powder, and can get large particles of more than 100 microns.

YMANLAB-W2L-304P small laboratory freeze spray dryer is also an excellent choice for materials that require direct access to nanomaterials.

Some laboratories are used for the preparation of conventional powders or for drying materials. You can use Shanghai Yacheng YMANLAB-W2L-304P laboratory spray dryer. YMANLAB-W2L-304P is small in size, fast in speed, low in noise, easy to operate, and 20ML. The material can be completed in one experiment. The dried powder has good sphericity and the particle size is too distributed. Especially the machine has a spray head water cooling device and a tower wall purging function, which greatly expands the application of the laboratory spray dryer. For some special materials containing chloride ions, the suitable models made of special stainless steel resistant to chloride ions can meet the actual needs of special industries.
