Лабораторный пилотный аппарат для сушки порошка с небольшим

The spray dryer is a drying equipment for processing solutions, suspensions or slurry-like materials. It uses the spray method to make the materials become mist droplets and disperse in the hot air. The materials and the hot air contact each other in a co-current, counter-current or mixed flow manner, so that the moisture can quickly evaporate to achieve the purpose of drying. When this drying method is adopted, unit operations such as concentration, filtration, and pulverization can be omitted, and granular products of 30~500μm can be obtained. The drying time is very short, generally 5~30s. It is suitable for the drying of highly heat-sensitive materials and materials that are easily dispersed in the process of liquid concentration. The product has good fluidity and instant dissolution.

The experimental spray dryer (small spray dryer) has a compact design and can be independently placed in a laboratory or placed on a specially designed stainless steel frame. It is self-contained and can run without other facilities. One-button boot, large color LCD touch screen operation. It can adopt two operating modes, fully automatic or manual monitoring, which is convenient for operation and monitoring of the experimental process. It is currently the smallest spray dryer with the smallest noise and excellent drying effect.

1. Fast drying speed. After centrifugal spraying, the surface area of the material liquid is greatly increased. In the high-temperature air flow, 95%-98% of the water can be evaporated instantly, and the drying time is only a few seconds.

2. The co-current spray drying method can make the droplets flow in the same direction as the hot air. Although the temperature of the hot air is higher, the hot air will immediately contact the spray droplets when the hot air enters the drying room, the indoor temperature drops sharply, and the wet bulb temperature of the material Basically unchanged. Therefore, it is also suitable for drying heat-sensitive materials.

3. Wide range of application. According to the characteristics of the material, it can be used for hot air drying, centrifugal granulation and cold air granulation. Most products with very different characteristics can be produced by this machine.

4. Since the drying process is completed in an instant, the particles of the product can basically maintain the approximate spherical shape of the droplets. The product has good dispersibility, fluidity and solubility. 

5. Simplified production process and convenient operation and control. Spray drying is usually used for solutions with a solid content of less than 60%. After drying, there is no need to pulverize and screen. This reduces the production process and simplifies the production process. For the particle size, density, and moisture of the product, within a certain range, the operating conditions can be changed for adjustment, and the control and management are very convenient.

 6. In order to prevent the material from being polluted and prolong the life of the equipment, all parts in contact with the material are made of glass or stainless steel.

7. After the material liquid is sprayed, it is atomized into dispersed particles. The surface area is greatly increased, and the drying process can be completed in a very short time after contact with hot air.

Refined nozzle, high efficiency.
Color LCD touch screen parameter display: air inlet temperature / air outlet temperature / peristaltic pump speed / air volume / needle frequenc.
Fully automatic control: One-button boot. After setting the spray process parameters, the temperature reaches the predetermined temperature, and the peristaltic pump starts by itself. The running animation is displayed on the touch screen, and the running process is clearly displayed. Just press the stop button when shutting down, and the machine will automatically shut down safely.

Manual control: If you need to adjust the process parameters during the experiment, you can easily switch to the manual state, and the whole experiment process is dynamically displayed on the color touch screen (animation)

Equipped with nozzle cleaner (through needle), when the nozzle is blocked, it will be automatically cleared, and the frequency of the through needle can be automatically adjusted.
Shutdown protection function: just press the stop button when shutting down. Except the fan, the machine immediately stops running to ensure that the equipment will not burn out due to misoperation (forcibly turning off the fan).

The spraying, drying and collecting system is made of transparent high-quality borosilicate heat-resistant glass material, so that the drying process can be carried out in a pollution-free environment.

Built-in oil-free air compressor, the particle diameter of the powder is normally distributed, the fluidity is very good, and the noise is very low, less than 60db.
 Atomization structure of two-fluid spray. The whole machine is made of high-quality stainless steel materials, with compact design and no need for auxiliary equipment. 
The design of the drying temperature control adopts real-time regulation PID constant temperature control technology, so that the temperature control of the whole temperature zone is accurate, and the heating temperature control accuracy is ±1℃.

In order to maintain the purity of the sample, it is equipped with an air inlet filter.
(For benzene, methanol, ethanol and other materials, it is safer to add a nitrogen device)
The feed volume can be adjusted by the feed peristaltic pump, and the small sample volume can reach 50ml.
The finished dry powder after drying has a relatively uniform particle size, and more than 98% of the dry powder is in the same particle size range.

For viscous materials, there is a nozzle cleaner (through needle), which will be automatically cleared when the nozzle is blocked, and the frequency of the needle can be automatically adjusted.

Innovative tower wall purging device, higher material recovery rate.

With special protection function, the heating cannot be started when the fan is not started. The air volume of the fan is adjustable.

1.LCD Touch Screen:Dynamically display air inlet temper ture/air outlet temperature/peristaltio pump speed/air volume/needle frequency.

2.Borosilicate Glass:High quality borosilicate glass, easy to clean, the whole spray drying experiment process is transparent and intuitive.

3.Realiable Sealing:The tight sealing provides a good sealing environment for the whole working process.

4.304 Stainless Steel:The machine is made of high quality stainless steel, which will never rust or corrode.
