Features of spray dryer for Chinese medicine extract:

      1. Design in strict accordance with GMP requirements

       The air is purified by primary, intermediate and secondary filters, and the treated air can reach 100,000 to 300,000 levels; the materials in contact with the internal air and materials are all made of high-quality stainless steel, and the surface is finely polished; avoid all pipes. There is a blind spot, the star discharge device and the main elbow can be easily disassembled and cleaned. In order to achieve corrosion resistance, no foreign matter falling off, no accumulation of materials, easy cleaning, no cross-contamination requirements, and full compliance with GMP standards.

Common problems and solutions of spray dryer for Chinese medicine extract:

High powder collection rate, reducing material loss

       A two-stage cyclone is used to select a suitable two-stage combination according to the characteristics of high-viscosity materials such as Chinese medicine extracts and seasonings. The first stage selects a high-processing cyclone separator, and the second stage uses a diffusion cyclone separator. The collection rate is as high as 99.5%.

Common problems and solutions of spray dryer for Chinese medicine extract

Effectively avoid adhesion, scorching and accumulation

        According to the characteristics of different materials, a gas cleaning device can be added to the tower to effectively remove the material adsorbed on the tower wall. The diameter of the tower body is scientifically and carefully calculated, which is larger than the diameter of an ordinary spray dryer, which increases the distance from the atomizer to the tower wall, prolongs the process time and reduces the droplets reaching the tower wall. Viscosity; The angle of the cone under the tower body is reduced to 52 degrees, and the number of pulsating vibrating hammers on the tower wall is increased, which greatly reduces the possibility of material adhesion on the tower wall; at the same time, the tower wall is provided. The air-cooled interlayer keeps the temperature of the inner wall within a certain range to avoid material coking; all elbows of the pipeline adopt an excessively large radius arc, and the pipe wall is effectively polished to make the material in the pipe very smooth and avoid accumulation.
