"To do a good job, must first sharpen their tools", for different physical or chemical properties of the material, as well as experiments need to get the size and solubility of the powder or particles, etc., the researchers may need a different type of laboratory spray dryer, in order to get the most ideal experimental results.
If the sugar content is relatively high (such as fruit juice, herbal medicine or natural product extracts) or heat-sensitive materials (such as enzymes live bacteria, etc.), because most of the polysaccharide disaccharides, the melting point is relatively low, when heated, the sugar melting, and polysaccharide disaccharides themselves are more prone to moisture absorption, so ordinary spray dryer, it will be easy to appear sticky wall of the phenomenon, it is not easy to get good dry powder or granule. In addition, like enzyme preparation, live bacteria and some high molecular materials that are easy to be denatured under high temperature, etc., using ordinary spray dryer, the material is very easy to be inactivated or denatured, then, reduce the inlet temperature and outlet temperature of the spray dryer can get better experimental results, the laboratory spray dryer and the laboratory low-temperature spray dryer can be used to carry out experiments at a relatively low inlet temperature, for example, the inlet temperature of YC-1000 laboratory spray dryer is very low, and the inlet temperature is very low, so it is not easy to get good dry powder or granule. 1000 Laboratory Spray Dryer's air inlet temperature can be set to 110 , general materials with high sugar content, can get better particles. Some materials of sugar, may be lower melting point, and YC-2000 laboratory low-temperature spray dryer, a clever combination of spray drying and vacuum drying advantages, in the 60-80 air inlet temperature, you can complete the spray drying process, such as enzyme preparations, live bacteria, etc., in such a low temperature instantaneous drying, the activity is not affected at all.
Again, the solvent for organic solvents or easily oxidized materials, spray drying contains organic solvent materials drying difficult problem, generally organic solvents will be flammable and explosive properties, explosion-proof closed laboratory spray dryer so that the material can be circulated in a closed drying system, the entire system is full of inert gas (such as nitrogen or argon), to avoid the contact of organic solvent gases and the outside world of oxygen, to ensure the safety of production. YC-015A experimental organic solvent spray dryer adopts the safety of nitrogen (or other inert gases) closed circulation mode, the whole system is closed, containing oxygen concentration online monitoring, once the concentration of oxygen in the system reaches 2%, the system will automatically mandatory shutdown and alarm, it is a safe and easy to operate laboratory organic solvent special small spray dryer, through the nitrogen (or other inert gas) closed circulation mode and take solvent completely, it can avoid the contact of organic solvent gas with the outside oxygen, to ensure the safety of production. It is a small spray dryer special for organic solvents in laboratory with good safety and easy operation, and it can be used in combustibility and toxicity solvents by means of nitrogen closed circulation and complete solvent recovery, and it can also be used for drying easily oxidizable substances. In addition, since organic solvents have a low boiling point, it is possible to dry substances that are susceptible to thermal denaturation by means of low-temperature drying.
In some experimental process, researchers want to get some large particles of samples, such as catalyst industry, generally need about 100 micron particles to have a better catalytic effect, but ordinary spray dryer, can only get the particles of less than 30 microns, YC-1000 Laboratory Spray Drying and Granulating Machine, can be better to achieve the experimental purpose. yc-1000 spray drying and granulating machine, both can be used to dry the particles, and can also be used to dry the particles, and can be used to dry the particles. YC-1000 spray granulator can be used as a separate spray dryer to get particles of about 100 microns, but also can realize the granulation of small powder particles, and can get large particles of more than 100 microns.
The materials with very poor heat sensitivity or need to improve the solubility, some materials, basically can not be subjected to heat, the traditional freeze-drying time is very long, and after drying the material into a block, poor fluidity, solubility is not very good. Compared with the traditional freeze-drying technology, YC-3000 laboratory spray freeze-dryer has the following advantages: atomization of dispersed tiny droplets immersed in low temperature quickly frozen, can weaken the growth of ice crystals, reduce the damage of ice crystals on the liposome, to avoid the leakage of materials, such as drugs and the sudden release of the material; freezing samples after drying by vacuum to form a spherical particles with a microporous structure, good mobility and the size of the particles can be adjusted by changing the spraying process. YC-3000 Laboratory Spray Freeze Dryer is suitable for low-temperature drying of heat-sensitive, viscous, active materials and materials with high sugar content, such as extracts of natural products of Chinese herbal medicine, dairy products, biological agents, enzyme preparations, fruit juices, polymer materials and so on.
For materials that need to get nanometer material directly, YC-3000 type laboratory spray freeze dryer is also an excellent choice.
Some laboratories for the preparation of conventional powder or material drying, you can choose Shanghai Yacheng YC-015 laboratory spray dryer, YC-015 small size, fast speed, low noise, easy to operate, and 20ML of the material that can be completed an experiment, the drying out of the powder sphere degree is good, the particle size into the distribution of the positive and too, in particular, the machine with a spray head water-cooling device and the wall of the tower In particular, the machine has spray head water cooling device and tower wall blowing function, which greatly expands the application of laboratory spray dryer. For some special materials containing chlorine ions, the use of chlorine ion resistant special stainless steel carefully made for the applicable models, to meet the actual needs of special industries.
