Hemoglobin spray dryer is a device used to dry hemoglobin solution into powder or granular products, which belongs to the application of spray dryer in hemoglobin processing field. The following is a detailed introduction:
After being filtered and heated, the air enters the air distributor at the top of the dryer, and the hot air enters the drying chamber uniformly in a spiral shape. The feed liquid is sprayed into extremely fine atomized liquid beads by the high-speed centrifugal atomizer at the top of the tower body, and is in parallel contact with hot air. In a very short time, the moisture in the liquid beads evaporates rapidly and is dried into finished products. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, while the exhaust gas is discharged by the fan.
Fast drying speedAfter atomization, the surface area of the material liquid is greatly increased. In the hot air flow, 95% -98% of the water can be evaporated instantly, and the drying time is only a few seconds. It is particularly suitable for drying heat sensitive hemoglobin.
The product quality is good.The dried hemoglobin product has good uniformity, fluidity, and solubility, and high purity.
Simplify the production processFor hemoglobin liquid with a moisture content of 40% -60% (special materials can reach 90%), it can be dried into powder products in one go, without the need for crushing and screening after drying, reducing production processes and improving product purity. At the same time, indicators such as product particle size, bulk density, and moisture can be adjusted within a certain range by changing operating conditions, making control and management very convenient.
The common hemoglobin spray dryer models are LPG -5, LPG -25, LPG -50, etc. Taking LPG 50 as an example, its inlet temperature is 150-250 ℃ (automatic control), its outlet temperature is about 80-90 ℃, its water evaporation capacity is 50kg/h, the rotational speed of centrifugal spray head is 18000r. p.m, and the diameter of spray disk is 120mm. The heat source can be steam+electricity, fuel oil, gas, etc.
