Desktop Spray Drying Mechanism

The principle of small spray dryer:  

The spray dryer mechanism small scale may be described as a multi-purpose machine, which can not only dry the materials, but in addition perform granulation work. The machine has some nice advantages of quick drying speed, high uniformity, good fluidity and solubility, high drying purity of the product and sterilization operate. At present, spray dryer small scale have been broadly used to dry some heat-sensitive liquids, suspensions and viscous liquids, such as milk, egg liquid, medicinal materials, extracts, inorganic salts, and so forth. The drying quality of materials may be very ideal. The laboratory vacuum bench scale spray dryer for sale is specifically developed for heat-sensitive supplies. The whole machine is compact and self-contained, and could be operated without different amenities. One-button start-up, massive shade LCD touch screen operation, totally computerized or guide monitoring two working modes can be utilized, which is convenient for operation and monitoring of the experimental course of, especially the moment drying of supplies under low temperature situations, which is extremely handy for heat-sensitive supplies. Extremely secure drying methods, corresponding to biological merchandise corresponding to enzyme preparations and reside bacteria, pure product extracts of conventional Chinese medicine with high sugar content, heat-labile polymer materials, supplies that vaporize when heated, etc. 


The working principle of fog dryer: 

After filtering and heating, the air enters the air distributor at the high of the dryer, and the new air enters the drying chamber evenly in a spiral form. The feed liquid passes through the high-speed centrifugal atomizer at the top of the tower physique, (rotationally) sprays into extremely nice mist-like liquid droplets, which can be dried into finished merchandise in a very quick time frame in co-current contact with scorching air. The finished product is repeatedly output from the bottom of the drying tower and the cyclone separator, and the exhaust gasoline is evacuated by the fan. The working means of the spray dryer mechanism scale is that the fabric and liquid are input by way of the diaphragm pump at high strain, sprayed with mist droplets, and then circulate down with the new air. Most of the powder particles are collected by the discharge port on the bottom of the tower. The separator is separated, the exhaust gas is discharged by the exhaust fan, and the powder is collected by the pollination cylinder located on the lower end of the cyclone separator. When the fabric liquid is fed into the feeding pipe of the atomizer, after one or two distributions of the fabric and liquid, it's quickly despatched to the high-speed rotating atomizing disk. It stretches to kind a skinny film and moves to the sting of the disc at an increasing speed. When it leaves the edge of the disc, the material liquid is atomized, with drop-like, filamentous and film-like splits. Which split is the primary one is decided by the The speed of the atomizer, the amount of feed, the properties of the fabric and liquid, and the form and diameter of the atomizing disc are related to elements such as the shape and diameter of the atomizing disc, and the size of the droplet primarily is dependent upon the peripheral velocity of the atomizing disc. 

Composition of small spray dryer:

The small spray dryer on the market consists of fans, heaters, air compressors, peristaltic pumps and atomizers. It is mainly used in universities, research institutes and laboratories of food, medicine and chemical enterprises to provide micro-particle powders. It is suitable for all solutions corresponding to emulsions, Suspension has broad-spectrum applicability, and scale-up production wants to start from small test, so the use of laboratory spray drying tools is a crucial step to discover data in the early stage. The loss and waste of materials caused by means of production gear for experiments. Using a menu-type microprocessor controller, it's potential to immediately set the inlet temperature, air circulate, computerized needle penetration frequency, and peristaltic pump speed to comprehend knowledge acquisition and process monitoring and management. The self-priming peristaltic pump sends the pattern liquid from the container via the nozzle into the drying chamber, whereas the compressed air enters the drying chamber from the outer sleeve to make the liquid micronized, and the hot air enters from the upper layer to satisfy the sprayed liquid particles, and the items begin to dry, dry The latter particles are separated from the waste gasoline by the cyclone separator after which enter the collection bottle, and the waste fuel is immediately discharged to the ambiance or air filter device via a diameter hose. 


Advantages of small spray dryer:

The complete machine of the spray dryer mechanism small scale is treated with anti-corrosion. It adopts double-stage heating, and the set temperature is reached in one or two minutes, which is handy and faster to begin the experiment. Compared with different bench scale spray dryer on the market available on the market, it has a lower moisture content within the powder output; the nozzle adopts a concentric nozzle. Design, steady uniform atomization during the experiment, and the fabric does not stick to the wall; the user-friendly primary interface setting does not require frequent switching in the course of the experiment, and the experimental parameters may be saved for next use; the interface is sealed with a gasket and a totally enclosed clamp , do not leak. 

The strategy of using the spray dryer: 

In fact, there are tons of advantages that may be loved through the use of a small spray dryer to dry totally different materials. It can dry the material into powder in a brief time, which not solely successfully improves the drying effectivity, but additionally saves some processing hyperlinks and simplifies the processing process. In addition, using a small spray dryer for drying, it may also be flexibly adjusted based on precise needs to meet completely different drying wants. From the evaluation of the actual work state of affairs, the drying process of the spray dryer may be divided into 5 steps. 

The first stage is material preparation, which is definitely to arrange the materials that have to be dried upfront. 

The second stage is to atomize the material, in order that the drying area of the fabric may be increased and the drying course of may be accelerated. 

The third stage is drying, which means that the bench scale spray dryer for sale dries the material according to the set process circumstances, in order that the moisture can shortly evaporate from the surface of the material. 

The fourth stage belongs to the separation of moist gas powder. 

The fifth stage is cooling and packaging. 

From the content launched above, we can really know that within the means of working the small spray dryer, cheap parameters should be set according to its own course of circumstances and material properties, so as to make sure the drying impact.
