SUS304 milk powder Centrifugal Atomizer Spray Dryer with steam heating and PLC and HIM control system

LPG Series milk powder  Centrifugal Atomizer Spray Dryer/Egg Powder Extracting Spray Drying Machine /Egg Powder Water Evaporating Dehydrator

Working principle and system description:

1,principle of operation

The unit for open cycle, and flow, centrifugal atomization, micro negative pressure operation. After air drying medium, medium efficiency air filters pre-filtered according to the operation instruction by the blower from using high efficient air filter purification after reaching one hundred thousand by steam heater and electric heater into hot air, and then enter the hot air distributor the main drying tower. The liquid material according to the operation instruction through the screw pump into the high-speed rotation of the centrifugal nozzle, under the action of centrifugal force is dispersed into small droplets. The main drying tower, small droplets and hot air in full contact, exchange heat along its path after being dried to become specific products, and then through the cyclone separator separated. The solid material was collected, filtered after gas is discharged.

The receiving system of the unit by the cold air cooling refrigeration dehumidification unique technology advanced material collecting device, which ensure the material from the instant high temperature region to avoid material is softened and cooled, and can avoid the material in high humidity environment such as moisture absorption phenomenon.

Performance description and characteristics of spray dryer

1,Feed system

It is composed of screw pump and feed pipe and valve.

The screw pump adopts frequency conversion speed regulation to effectively control the feed quantity. The main part of the pipeline valve is SUS304 stainless steel, and it is clean and sanitary

2,Medium circulation system

It is composed of blower, draft fan, muffler, air regulating butterfly valve and wind pipe

Draft fan and blower are high quality manufacturers supply, cooperation for many years, quality is stable; the blower for SUS304 stainless steel, to ensure clean air; fan with a silencer, effectively reduce the noise. The system volume, wind pressure, wind speed, is the key, based on years of experience, is now mature.

3,Air heating and cleaning system

It consists of early, medium and high temperature HEPA filters, fans, steam radiators, electric heaters, etc.

The heat source is a steam radiator and an electric heater. The material is made of stainless steel pipes and stainless steel fins. The utility model not only ensures the cleanness of the air inlet system, but also has high thermal efficiency and can guarantee the output heat

4,Drying tower system

It is composed of a dry main tower, a hot air distributor, an atomizer, an observation manhole, a tower lighting device, a pneumatic hammer, a lower bin, a cylinder body and a cone jacket, and a cooling system

This system is the core system

1, combined with the test experience, we in the design process of the main tower of the main tower: adjust the straight cylinder height to diameter ratio, adjusted by 0.9:1 routine to about 1.1:1; prolong the retention time of the material, the drying effect is ensured. The adjustment of the taper cone tower, consists of a conventional 60 degree angle adjustment to 54 degrees, fully considering the smooth material in the cone when feeding.

2, the atomizer atomizer using frequency converter to adjust the speed to achieve the best effect. The base will reduce the atomizing atomizer, the atomizing disk atomizer and increase the distance, the droplets in the air can not be returned under the spinning top, in order to ensure the normal operation of the system.

3, design a set of Taneiduo lighting devices and 1 doors, manholes.

4, hot air vortex shell tower by accelerating structure, the hot air in the tower when pressed material effectively, orderly and swirl decreased. Hot air distributor with the characteristics and requirements of the technology, do both sides distributor the wind guiding mechanism, and can adjust the angle, in order to control the hot air into the tower when the tangential angle.

5, the main tower design of jacket cooling cooling system: to avoid the main tower body wall temperature is too high and the receiving effect of the adsorption tower in the cone wall material by high temperature and coking softening phenomenon, ensure the quality of the materials.

5,Product collection system

The utility model is composed of a cyclone separator and a water film dust collector

6,Cold desiccant charging system

It is composed of air filter, freezing dehumidifier, cleaning pipe and so on. The system sends the fresh air to the clean area and collects the cooling air after the filtered fresh air passes through the refrigeration dehumidifier.

7,Other auxiliary system

Are well-known manufacturers of supply, reliable performance; some pipes take into account a certain angle design, the use of suppression stainless steel pipe, to avoid the end material, blocking material, and local resistance is too large, affecting the phenomenon of material delivery.
