Spirulina dryer

1、 Overview of Spirulina

Spirulina is a kind of lower plants, belonging to Cyanophyta, Oscillatoriaceae family. They, like bacteria, do not have a true nucleus in their cells, so they are also known as cyanobacteria. The cellular structure of blue-green algae is primitive and very simple, making them the earliest photosynthetic organisms to appear on Earth. They have lived on this planet for 3.5 billion years. It grows in water and can be seen under a microscope as a spiral filament, hence its name.

2、Advantages of Spirulina dryer

1) Using circulating hot water as a heat source to improve drying efficiency;

2) The drying conditions are mild, and the product temperature is relatively low, maintained at approximately 70 ℃;

3) Operating under low temperature and normal pressure conditions can effectively preserve the color and nutrients of the product, reducing the degree of oxidation of the product;

4) The drying time is about 3-5 minutes short;

5) Can dry most liquid materials without the need for non sugar carriers;

6) Adopting modular design, capable of continuous operation;

7) Low energy consumption.

3、 Applicable scope of spirulina dryer

After testing and production, the liquid paste material flash dryer is the most suitable for heat sensitive materials.

Mainly including:

Fruits: such as apples, pears, mangoes, etc;

Nutrients: Spirulina, seaweed, barley grass juice, yeast, etc

Beverages: coffee, tea, etc

Waste: soybean residue, muddy materials, etc

4、Spirulina dryer Drying conditions：

The factors that restrict dryness on Spirulina dryer include air inlet temperature, exhaust temperature, air humidity, dry air volume, material liquid treatment, water evaporation, dry room diameter, dry room volume, particle diameter.

When designing the above factors, according to the characteristics of dry materials, the particle size and processing of the required product are determined, especially the diameter and volume of the dry chamber. Because they are indispensable factors, it is not possible to make too many adjustments based on this. Therefore, before the design of the Refractive window dryer, it is very necessary to select appropriate drying conditions on a small test machine.
