Potato starch dryer manufacture

The working principle of the starch dryer is to send the granular wet material into the hot air flow and flow in parallel with it to obtain the granular dry product
The starch dryer is to mix the wet raw material with the high-temperature air flow, so as to separate the water from the raw material through the separator
Dryers are widely used in food, feed, chemical industry, medicine, mining and other industries
The working process of drying equipment is as follows: after the dehydrated wet materials are added to the dryer, they are thrown into the pipeline with a throwing elevator
The materials are evenly dispersed in the dryer and come into contact with hot air to accelerate drying heat and mass transfer

Starch dryer adopts the principle of instant drying by air flow, which has the characteristics of high drying intensity, short drying time, less energy consumption, simple Cao operation and good product quality
The starch dried by this equipment has the advantages of clean appearance, luster, high fineness, stable water content, low impurity pollution and so on
Starch dryer is an ideal equipment for drying powder, flake and heat sensitive materials in starch, rice flour, food, medicine, chemical industry and other industries
Using this equipment can achieve better economic benefits with less investment, lower energy consumption, less manpower and site, and faster speed

Function of starch dryer
  Starch dryer uses high-speed hot air flow to suspend wet starch and dry it in the process of air flow
It has the characteristics of high heat transfer coefficient, large heat transfer area and short drying time
The airflow drying device with a disperser is equipped with a throwing elevator under the drying pipe to disperse and throw materials
It is suitable for block materials with low water content and good looseness, such as filter cake of centrifuge and vacuum dehydrator
  Air drying is also called & ldquo; Instant drying & rdquo; It is the application of dilute phase transportation in drying in solid fluidization
The method is to make the heating medium directly contact with the solid particles to be dried and suspend the solid particles to be dried in the hot gas flow
Therefore, the two-phase contact area is large and the heat and mass transfer process is strengthened
It is widely used in the drying unit Cao of bulk materials

Advantages of starch dryer
1
Short drying time and large processing capacity
Due to the short gas-solid contact time, it is suitable for the drying of heat sensitive or low melting point materials

2
The drying rate is fast and the drying time is only a few seconds
With high drying intensity, automatic continuous production can be realized

3
Simple structure, small floor area and convenient manufacture

4
Wide adaptability
Larger particle size can reach 10-35μ M
for bulk granular materials, the moisture content can be between 10% - 25%

Precautions for use
1
All lubricating parts of the starch dryer shall be lubricated before use;
2
Before the starch dryer is officially put into use, the equipment shall be adjusted to make the starch dryer play a better drying role;
3
When using the starch dryer, pay attention to the sequence of opening and closing Cao, so as not to affect the drying effect;
4
Adjust the scraper centrifuge or vacuum Dehydrator in front of the starch dryer to make the moisture of wet materials low and stable and feed evenly in the feeder;
5
Pay attention to the Anquan property around the starch dryer and take Anquan measures
