The so-called vacuum spray dryer actually refers to a device capable of drying, which can meet the requirements of continuous feeding and discharging under vacuum, and the amount of feed can be set as needed. The operation is very flexible. In addition, the heating system of the vacuum spray dryer can use various forms such as steam, hot water or electric heating.

During the drying process, we can make any adjustments in the temperature range of 25 ° C - 80 ° C. Generally, after 20 minutes to 60 minutes, the vacuum spray dryer starts to discharge continuously until the drying task is completed. Since the track of the equipment is made of Teflon material, it can not only ensure smooth and reliable performance, but also make the heating area more uniform during operation.
Of course, its speed can also be adjusted according to actual needs. In addition, the vacuum spray dryer can also be used in combination with different distribution devices to meet the drying requirements of different materials, such as the ability to dry materials such as liquids, extracts and powders.
In addition, the vacuum spray dryer is specially equipped with an automatic pulverizing system under vacuum, so the user can select the dry granules as needed. The unit is also equipped with an in-place cleaning system that automatically cleans and saves a lot of time. In the process of operation, the equipment not only has low energy consumption, but also does not generate harmful substances, and the working noise is also small.
In short, the vacuum spray dryer has many advantages in practical applications, which enables it to actually help the users and friends in the drying operation to help complete the production task.
Experimental spray drying machine protection function
â— Shutdown protection function: After the instrument is finished, the working state of the fan should be kept, so that the glass is partially cooled. The machine is set by intelligent program. When the inlet temperature is lower than 30 degrees, the fan is automatically turned off, no manual manual shutdown of the fan is required; protection equipment Do not overheat the heating element due to misuse (forced shutdown of the fan)
â— Time setting function: The user can set the working time of the machine by himself, without manual guarding, and the working time ends the machine to stop working, which greatly saves the precious time for the customer to do the experiment.
â—The laboratory small spray dryer has a built-in oil-free air compressor. The air compressor is equipped with a stainless steel gas storage tank. The diameter of the powder spray is normally distributed, the fluidity is good, and the noise is very low, which meets the national laboratory noise standard.
â—The atomization structure of the two-fluid spray, the whole machine body is made of high-quality stainless steel material with precision design, compact design, no need for auxiliary equipment, convenient use, and lasting as new.
â—The spray, drying and collection system is made of transparent high-quality borosilicate heat-resistant glass material, so that the drying process can be carried out in a non-polluting environment; and the whole spray drying experiment process is transparent and intuitive, all the original glass parts are easy to be removed and washed;
◠In order to meet the requirements of the user to adjust various parameters in the experimental range, the real-time control PID constant temperature control technology is adopted in the design of the drying temperature control, so that the temperature control in the full temperature zone is accurate, and the heating temperature control precision is ±1 °C.
How the spray dryer works
Spray Dryer The spray dryer is a dryer that processes solutions, suspensions or slurry materials. The spray dryer uses a spray method to disperse the material into a hot gas stream, and the material and the hot air are in contact with each other in a cocurrent, countercurrent or mixed flow manner, so that the water is quickly evaporated to achieve the purpose of drying. By using this drying method, the chemical unit operation such as concentration or filtration can be omitted, and a granular product of 30-50up can be obtained, and the drying time is extremely short. Generally drying time is 5-30s, spray dryer is suitable for high thermal fog dryer. Only in production capacity greater than '100kg (water) / h
It is more economical when it is strong.
Spray-dried products are fine particles. In order to meet the requirements of the Environmental Protection Law, it is not enough to use a cyclone to separate products and purify exhaust gas. It is generally necessary to purify with a bag filter to make the dust in the exhaust gas. The quantity is lower than 50 gas (standard state), or the wet scrubber can reduce the dust content of the exhaust gas. The traditional LPG high-speed centrifugal spray dryer has maintained its best-selling trend in the chemical industry since the first half of the year. More demanding ZLPG type Chinese medicine extract spray dryer and TPG type intelligent seasoning spray dryer are increasingly prominent in the market, and are purchased for the majority of pharmaceutical companies and food factories.
The technical equipment for ceramic raw material processing has not had much breakthrough for many years. In the production process of the powder, the spray dryer realizes the unmanned monitoring system, which can analyze the key data of the inlet and outlet air temperature, the air volume, the mud pressure and the moisture in the spray dryer through the processing software, and analyze the system changes in real time. Factors, and can simulate the manual operation to adjust the temperature of the hot blast stove, the flow rate of the slurry, etc., and finally replace the human operation. In order to improve the utilization and quality of the powder, a spray tower powder cooler capable of rapidly cooling the powder temperature and controlling the humidity of the powder has been introduced.
The spray dryer of China's ceramic machinery enterprises has taken a leap step in the use of fuel in the past two years.
The original burning oil turned into a clean energy using coal-water slurry, which not only saved fuel costs, but also reduced pollution to the atmosphere.
. Spray dryer is one of the main process equipment of ceramic enterprises, the energy consumption of this link accounts for the total energy consumption of the production line.
Very large, the cost of using coal water slurry can reduce the cost by 20% compared with burning oil, so the promotion of coal water slurry is very fast, only one
The amount of time is much higher than the value of the power industry, becoming the leading industry for coal water slurry.
