Pressure Spray Drying Machine Composition

1. Feeding System

The peristaltic pump adopts the step speed regulation, and the feeding volume matches the discharge air temperature to precisely control the discharge air temperature.

2. Media Circulation System

This system is composed of supply fan, induced draft fan, air regulating butterfly valve, air duct, and so on. The matching of air volume, air pressure and airspeed in this system is the key.

3. Air Heating And Purification System

This system consists of primary and secondary air filters, fans, coil fin radiators, etc.
The heat source is electric heating, and the heating tube is made of stainless steel with finned radiator, which has high thermal efficiency and greatly extended service life.

4. Drying Tower System

This system is the core system, consisting of the main drying tower, hot air distributor, atomizer, observation manhole, lighting device in the tower, pneumatic hammer, etc.

5. Receiving System

The receiving system of the spray drying unit is formed by the combination of cyclone separator + cloth bag dust collector. The cyclone adopts high air volume and high-efficiency cyclone for collection, and its collection rate can reach about 95%, while the cloth bag dust collector is specially designed for protein powder dust removal optimization equipment, which can make the material and wind completely separated and settled, and the filter mesh can reach more than 500 mesh.

6. Control System

It is composed of the main control element, programmable touch screen, fuzzy controller, etc.

The system color touch screen animation display process flow, control set the relevant parameters.

PLC programmable control, touch screen animation display process flow; according to the discharge air temperature automatically adjust the feed volume speed; digital display temperature, pressure, differential pressure, frequency conversion to adjust the atomization speed, etc.

7. Cool Air Centralized Material Collection System

It is composed of air filter, refrigerated dehumidifier, clean duct, fan, etc.

Filtered fresh air after passing through the refrigerated dehumidifier, it quickly becomes dry and low temperature, and forcibly sent into the material-filled cyclone separator under the collection bin, so that the material cools, which has two advantages:

Maximum reduction of the relative humidity in the aggregate bin, to prevent the material from being returned to moisture in the natural cooling process in the aggregate bin, thus avoiding the phenomenon of moisture absorption and caking of materials.
25℃ dehumidifying wind controls the temperature in the aggregate bin at about 40℃, which is a good solution to the problem of protein powder being softened by high temperature and ensures the fluidity of the product.
