GZ-S series centrifugal granulation spray dryer

Centrifugal spray dryerHigh degree of automation, easy operation, good product quality, suitable for solutions, lotion, suspensions, and even liquid materials with viscosity.

so-calledCentrifugal spray dryingThe machine utilizes centrifugal technologynebulizerDrying certain liquid materials is one of the widely used drying machines in industrial production. Spray drying is widely used in liquid forming and drying industries. It is used to generate powdery and granular products in solutions, lotion, suspensions and pumpable lake liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape meet the standard, spray drying is a very ideal process.

centrifugationSpray dryerCharacteristics:

1. Fast drying speed, greatly increased surface area of the material after atomization, and instant evaporation of 95% -98% of moisture in hot air flow. It only takes 5-15 seconds to complete the drying process and has the characteristic of instantaneous drying.

Two special air distribution devices reduce equipment resistance and effectively provide the air conditioning system for the dryer.

Simplify the production process and make it suitable for continuous control of production. Liquid with a moisture content of 40-90% can be dried into powder in one go, reducing the need for crushing, screening, and other processes to improve product purity.

The drying process of 4 materials can be completed in a short period of time, which is suitable for drying heat sensitive materials and can maintain the color, aroma, and taste of the materials.

5. The product has good dispersibility, fluidity, and solubility. The particle size, looseness, and moisture content of the product can be adjusted within a certain range.

process flow
　　Pressure spray granulation dryerIt mainly consists of a feeding system, a drying system, a dust removal system, a heating system, and an electrical system, each of which includes some related equipment.
The feeding system consists of a mixing tank, a filter, a diaphragm pump, and a spray gun. The secondary slurry that has been ball milled is transferred from the ball mill to the mixing tank, and is extracted and transported by a diaphragm pump through a filter, and then enters through a spray gundrying towerInside.
The slurry enters the drying tower from the spray gun nozzle and beginsSpray granulation dryingThe process is divided into three stages:
(1) Atomization of slurry.
The slurry is pumped into the drying tower from the nozzle by a diaphragm pump in the feeding system at a certain pressure. The energy of the pressure is converted into kinetic energy, and the slurry is sprayed from the nozzle from bottom to top, forming a high-speed liquid film. The liquid film then splits into droplets. The droplet size generated by atomization is inversely proportional to the pressure, and the production capacity of the nozzle is directly proportional to the square of the pressure.
(2) The mist particles dry into balls.
Mist particles and hot air work in a mixed flow. Hot air enters the tower through the hot air distributor on the top cover, and the hot air distributor generates a downward streamline airflow. Mist droplets are sprayed into the hot air flow from bottom to top. Droplets form spherical shapes due to surface tension, and due to their large surface area, water evaporates rapidly and dries, eventually shrinking to form dry spherical particle powders.
The spherical particle powder formed gradually settles in the drying tower and separates from the hot air. The funnel-shaped cavity at the bottom of the tower collects the particle material and discharges it from the outlet. Finer particles are extracted together with dry air by a suction fan connected to the upper part of the funnel and enter the dust removal system.
(3) Unload the granular powder material.
The air supply fan, drying tower, and exhaust fan that transport hot air to the drying tower form the drying system.
The dust removal system consists of an efficient cyclone separator, bag filter, centrifugal fan, etc. The exhaust fan sends finer particles together with dry air into the high-efficiency cyclone separator. After effective separation, finer particles are collected in the collection cylinder at the bottom of the separator. The remaining waste gas containing a small amount of fine particles is sucked into the bag filter by a centrifugal fan and collected again, achieving harmless treatment of the waste gas. The waste gas is discharged from the chimney.
In addition, the heating system composed of electric heaters and gas turbine hot air stoves provides hot air for the drying tower. The electrical system consisting of an electrical control cabinet and on-site sensors installed at the inlet and outlet to monitor temperature has a significant impact on the entire systemSpray granulation dryerMonitor and control all major aspects of the equipment to ensure its normal operation.
