Stainless Steel Milk Powder Making Machine Centrifugal Atomizer Spray Dryer
Detail
It is mainly used in universities, research institutes and laboratories of food, medicine and chemical enterprises to produce micro-particle powders. It has broad-spectrum applicability to all solutions such as emulsions and suspensions, and is suitable for drying of heat-sensitive substances such as biological products and biological pesticides. , enzyme preparations, etc., because the sprayed materials are only exposed to high temperature when they are sprayed into mist-shaped particles, so they are only heated instantaneously, which can keep these active materials from being damaged after drying.
Main features
The working principle of this machine is that after the air passes through the filter and the heating device, it enters the hot air distributor at the top of the drying chamber, and the hot air passing through the hot air distributor enters the drying chamber evenly, rotates in a spiral shape, and sends the material liquid to the device at the same time. At the centrifugal spray head at the top of the drying chamber, the material liquid is sprayed into high-performance mist droplets, which greatly increases the surface area of the material liquid and hot air contact, and the moisture evaporates quickly, drying the finished product in a very short time. The coarser finished product is recovered by the collection cylinder at the bottom of the dryer, and the exhaust gas is discharged by the centrifugal fan.
Feature
1. The drying speed is fast. After the material liquid is sprayed by centrifugal spray, the surface area is greatly increased. In the high temperature air flow, 95-98% of the water can be evaporated instantly, and it takes more than ten seconds to complete the drying time.
2. The co-current spray drying is adopted. During the drying process, the temperature of the droplets is not high, and the product quality is good. In the spray drying room, the droplets flow in the same direction as the hot air. Although the temperature of the hot air is high, the room temperature drops sharply because the hot air enters the drying room and immediately contacts the spray droplets, which will not cause the drying material to be overheated, which is suitable for the drying of heat-sensitive materials. For drying, the temperature of the discharged product depends on the exhaust air temperature and is lower than the exhaust air temperature.
3. Wide range of use. According to the physical properties of the material, it can be dried with hot air or molded with cold air. A large number of products with very different characteristics can be produced by this machine. Chang Yong has the following categories: polymers and resins, dyes, color pigments, ceramics, glass, herbicides, insecticides, carbohydrates Compounds, dairy and egg products, mixed acids, by-products of slaughterhouses, blood and fish products, detergents and surface stains, fertilizers, organic compounds, inorganic compounds.
4. Since the drying process is completed in an instant, the particles of the product can basically keep the spherical shape of droplets, and the product has good dispersibility, fluidity and solubility.
5. The production process is simplified and the operation control is convenient. Spray drying is usually used for solvents with a moisture content of 40-60%. Even if the moisture content of special materials is as high as 90%, it can be dried into powder products at one time. Most products do not need to be pulverized and screened after drying, which reduces the production process. The production process is simplified and the purity of the product is provided. The particle size, precision, and moisture of the product can be adjusted by changing the operating conditions within a certain range, and it is very convenient to control and manage.
6. In order to keep the material from being polluted and prolong the life of the equipment, all parts in contact with the material are made of 304 stainless steel. close the device.
