A precision spray dryer

Abstract

The invention relates to a precision spray dryer, comprising a drying tower, an atomizer, a diffusion mechanism, a jet pipeline, a cyclone separator, a material storage box and a bag filter. The tower body and the lower tower cone are connected up and down, the top of the upper tower body is provided with a guide chamber, the atomizer is installed in the guide chamber, and the atomizer is connected to the liquid storage through the liquid inlet pipe. The tank is connected to the tank, the feed pump is installed on the liquid inlet pipe, the diffusion mechanism is installed at the outlet of the diversion chamber, the injection pipe is arranged in the upper tower body, and one end of the injection pipe is connected to the inlet pipe. The cyclone separator is connected to the bottom of the lower tower cone, the storage box is arranged at the bottom of the discharge port of the cyclone separator, and the bag filter is connected to the outlet of the cyclone separator through the air outlet pipe. At the mouth. The design has the advantages of simple structure, easy manufacture, practicality and high efficiency.

Description

technical field [0001] The invention relates to a dryer, in particular to a precision spray dryer. Background technique [0002] Spray dryers are widely used in chemical fields such as dyes, pesticides, and ceramics. For drying high-viscosity heat-sensitive materials such as K30 and oligosaccharides, traditional spray drying equipment cannot be continuously produced, and the materials are easily adhered to the inner wall of the machine, making the work efficiency very low, and it takes a lot of manpower and material resources to clean, and K30 The material is very sensitive to the humidity in the air, and it is easy to absorb moisture and affect the quality of the product; in terms of exhaust emissions, most of the current equipment is directly discharged to the outside, which not only wastes a lot of energy, but also does not meet the national emission reduction regulations. Energy-saving standards. Traditional equipment has great defects in these aspects. Contents of t...
