Enzyme preparations refer to biological products with catalytic function after enzymes are purified and processed. Enzyme preparations are widely used and are mainly used as pharmaceutical intermediates, additives for food processing and growth promoters for livestock and poultry breeding. In addition, it is also used in textile, light industry, leather, paper, oil extraction, construction, environmental protection, military and other industries. Griffin drying engineering and technical personnel have been devoted to the research and development of special dryers for enzyme preparations for many years, and have targeted the characteristics of materials with high viscosity.

Enzyme preparation Dryer:

The special dryer for enzyme preparations developed by our company adopts a fully enclosed form, all parts are made of stainless steel, equipped with a three-stage purification device, and the filtered air reaches the requirements of 100,000 grades. The cylinder body and the top are equipped with a cold wall device to make the wall temperature <80℃, and the drying tower is equipped with an air brush sweeping tower device. The product dried by this machine will not appear coking and deterioration phenomenon, which greatly increases the powder collection rate (above 95%), and will not produce the phenomenon of drug mixing and sticking to the wall.

1. Production requirements:

1. The air entering the tower is filtered through three-effect filtration of primary effect, medium effect and high temperature and high efficiency.

2. The drying tower is operated under slightly positive pressure. Unpurified air will not enter the tower to contaminate materials.

3. The inside and outside of the equipment pipeline is polished, and some quick-opening cleaning holes are set on the pipeline.

2. Exhaust emissions meet environmental protection requirements:

1. It is composed of high-efficiency cyclone separator and water mist dust collector, and the recovery rate can reach more than 99%.

3. Solve the phenomenon of material adsorption and accumulation on the inner wall of the tower:

1. The material of the inner wall of the tower is made of SUS304 mirror panel, which minimizes the phenomenon of powder adsorption tower wall.

2. The tower diameter and tower height are correspondingly enlarged, and the taper is reduced to prevent material accumulation and coking.

3. Pneumatic percussion device is used for the straight cylinder and cone of the tower to prevent dust adsorption. The cone is cooled with jacketed cold air.

Spray dryers are now widely used in industry and have been adapted for liquid forming processes as well as in the drying industry. When the particle size distribution, residual moisture content and bulk density of the finished product meet the standards, a Spray Dryer can be used to achieve the drying process.

Regarding the characteristics of the enzyme preparation dryer, there are mainly:

Feature 1: The drying speed is very fast, and after the material liquid is atomized, its surface area can be increased. Therefore, the spray dryer can instantly evaporate most of the water in the process of contacting with hot air, and the drying time is only a few seconds, so it is especially suitable for drying heat-sensitive materials.

Feature 2: It has very good uniformity, and its fluidity and solubility are also good. The purity of the product is also very high, which can ensure high product quality.

Feature 3: The production process can be simplified and the operation is very convenient. With this kind of machine, the production process of the product can be reduced, and the operating conditions can be changed within a certain range, so as to achieve convenient control and management.
