Spray - Drying Tower For Milk Powder Manufacturing Processing Line
Turnkey project Complete milk powder Production Line, Milk Powder
Processing Line, Milk powder making machinery:
Working principle and configuration options
The solution, emulsion, suspension liquid or slurry are sprayed
into fine beads in the hot air, going down from the top of the
drying chamber to the bottom, the water will be evaporated to and
the product becomes powder or granular product.
Induce hot air from the top of drying tower, at the same time, pump
the material liquid to the top of the tower by screw pump or
peristaltic pump, the feeding solution becomes into fine beads or
small droplets through the atomizer. When the droplets meet the
high temperature hot air, the water will be evaporated immediately,
and the material liquid is dried into dry product in a very short
time, the product is discharged from the bottom of the drying
tower, or from the cyclone (depend on the configuration). When the
hot air contacts with the droplets, the temperature declines
significantly, and the humidity increases greatly, and then will be
exhausted by exhaust fan. The fine powder in the air will be
collected through different separating devices
There're different fine powder separation and recovery devices,
such as cyclone (the common type and various combination type), bag
filter, cyclone + bag filter, cyclone + wet scrubber, and bag
filter + wet scrubber etc. We should different fine powder
separation and recovery devices as per the characteristics of
product and requirements of customer.
Depend on the product features and requirements, we might install
secondary drying and cooling system (such as ZLG vibration fluid
bed or pneumatic transportation), formulation system or powder
sieving system etc after the spray dryer, or dehumidifier.
Notes for Inquiry:
1. Liquid material name and physical properties: Solid contents (or
moisture contents), viscosity, surface tension, pH value, etc. If
there's any other liquid, such as organic solvent, please specify
the name and percentage clearly.
2. Product characteristics: Final moisture content required, the
range of particle size, and heat sensitive temperature etc.
3. Special requirements (if any): Range of specific bulk density,
color, and flavor etc.
4. Working capacity (kg/h or ton/h). If the capacity is based on
per day, per month or per, please also indicate the working hours.
5. Heat source: It could be the pressure of steam, electricity,
coal, oil, natural gas, LPG and other combustible materials.
6. Control requirements: The way to control the air inlet
temperature, liquid supply system, pneumatic hammer etc, and the
type of the system control (normal push button type, PLC+HMI, and
PC system etc)
7. Fines collection type: Depending on the product characters and
environment protection requirements, we have following options,
cyclone, bag filter, wet scrubber and their combinations.
8. Other special requirements: Dimensions of the workshop, height
limit and special electricity requirements etc.
Our company can design customized milk production lines in
accordance to the customers' requirements. The production capacity
varies from 1000L/h to 10000L/h according to customer's need
Note: Jimei milk production lines can be widely used to produce
milk powder, UHT milk, pasteurized milk, setted milk, stirred milk,
milk drink, yogurt, ice cream, condensed milk, and so on.
