How to make dry starch/flour in the best way?

Normally the moisture content of the starch/flour after dehydration is 35% - 45%. Because it is easily deteriorate, after dehydration it must be dried. The current ways to dry starch/flour mainly include sun drying, drying room and automatic flash dryer. So how to make dry starch/flour in the best way? Which is the best way?

At first, i will introduce the different way to make dry starch/flour briefly.

Make dry starch/flour by sun drying

Advantages:

Small investment, simple method, suitable for small-scale starch/flour processing.

Disadvantages:

1. Long time, large labor input and high cost.

2. Greatly affected by weather changes.

3. Dust and bacteria cannot be isolated, and sanitary conditions are not guaranteed.

Making dry starch/flour by sun drying is only suitable for small-scale users. Once the processing capacity is large, the drying method will not work; or the weather is bad, and the drying is impossible at all which will cause starch/flour deterioration and serious losses.

Make dry starch/flour by drying room

Advantages:

Small investment, unaffected by the weather and relatively hygienic.

Disadvantages:

1. The quality is not easy to control, and the product is easy to dry outside and wet inside.

2. The temperature is not easy to control, and easy to be pasted.

3. Low drying efficiency, long time consuming and high labor intensity.

Make dry starch/flour by automatic flash dryer

The hot wind of automatic flash dryer is around 20m/s. It can ensure the moisture of dried starch/flour is around 13.5% ~14% within 2 seconds. If the capacity is larger, it is essential to match a automatic flash dryer.

Advantages:

1. It is suitable for large-scale industrial production.

2. The automatic flash dryer has high drying intensity and large evaporation capacity.

3. The drying time is short, and the finished starch/flour does not contact the outside world, effectively avoiding secondary pollution.

4. Energy saving and high efficiency, not affected by natural.

Disadvantages:

The price is relatively expensive.

After knowing the 3 different way to make dry starch/flour. We can clearly realize the biggest difference between the way to make dry starch/flour by sun drying and drying room and by automatic flash dryer is that they are dried at low temperature, and the finished starch/flour is granular powder with high moisture content. Besides, the first two drying ways require a special drying shed or drying field, which is inefficient. Although the cost of automatic flash dryer is relatively expensive, but in the subsequent production process, it shows unique advantages: automatic control, high processing efficiency, good starch/flour quality; short time, labor and space saving, and long service life.

Now i believe you probably have an idea of your own about how to make dry starch/flour in the best way. If you have a large capacity to make dry starch/flour, making dry starch/flour by automatic flash dryer must be the best choice for you. Surely it is best to choose the right one for yourself.
