where to buy horizontal spray dryer?
A spray dryer is a multi-purpose machine, which can not only dry the material, but also granulate it. This machine has the advantages of fast drying speed, high uniformity, good fluidity and solubility, high drying purity and strong sterilization function. At present, spray dryers have been widely used in the drying of some heat-sensitive liquids, suspensions and viscous liquids, such as milk, eggs, medicinal materials, extracts, inorganic salts, etc. The drying quality of the materials is very ideal spray dryer price.

Compared with traditional drying equipment, spray drying can solve the problems of long drying time, low efficiency and unstable quality. In the material drying process, the efficiency is usually improved by about 10 times compared with the traditional method. The dry quality of this material is very consistent. Perhaps because of this, spray dryers effectively play their role in the drying of food and traditional Chinese medicine with their many advantages.
So, in use, how do users know themselves and others, master the operation method of spray drying equipment, and achieve safe and high-quality production?
First of all, before the spray dryer is started, the user should prepare the necessary items for spray drying, clean the cooling barrel and the feeding barrel in advance, and check whether the feeding pump and feeding pipe are dripping. If possible, the user should also attempt to clean and dry the inside of the tank, powder collector, and piping. Then a certain amount of water is poured into the cooling bucket, and the feed solution to be spray-dried is poured into the feed bucket.
Second, further check and connect the dehumidifier, the collecting drum tube above the butterfly valve, and see if they are open. Additionally, the dampers on the spray tower should be fully open and the spray hatch doors should be closed. The quick installation clamps of each connecting pipe must be installed correctly, the outlet valve of the air compressor is opened, the exhaust valve is closed, and the air pressure pipe is well connected. The contact between the mist droplets and the hot air flow should be fully ensured so as to conduct sufficient heat exchange, thereby achieving the purpose of spray drying of the raw material liquid.
In addition, when the material enters the atomizer and starts spraying, the vibrator is turned on so that the user can observe the atomization and exhaust temperature. Because the atomization system must ensure the uniform distribution of the droplet size, in order to ensure the quality of spray-dried materials and improve the qualified rate of product quality. If the air temperature is higher than 90°C, the speed of the peristaltic pump can be adjusted slowly. The outlet air temperature dropped to about 86°C, which was the normal spray speed and remained stable. At the same time, the particle size, particle size, bulk density and moisture of the product can also be adjusted accordingly.
The spray dryer has good homogeneity, fluidity and solubility, so it has high purity and good quality. The production process is simplified and the operation control is convenient. Liquids with a moisture content of 40-60% (up to 90% for special materials) can be dried into powder products at one time. After drying, there is no need for crushing and screening, which reduces the production process and improves the product purity. By changing the operating conditions within a certain range, the particle size, bulk density and humidity of the product can be adjusted, which is very convenient for control and management. These advantages are widely used in the following industries:
According to the structure of the atomizer, drying equipment is divided into three types: centrifugal, pressure and air flow. It is suitable for drying solution, suspension or slurry material, especially suitable for drying materials with high heat sensitivity and easy dispersion during the concentration process. It adopts the spray method to make the material become water droplets and disperse in the hot air, and the material contacts with the hot air in the way of parallel flow, countercurrent or mixed flow, so that the water evaporates quickly and achieves the purpose of drying.
