Algae & Microalgae Dehydration Machine

Algae, Seaweed, Carrageenan dehydration is the process of removing water from algae, Seaweed, Carrageenan, typically for preservation, storage, or further processing. Algae, Seaweed, Carrageenan are photosynthetic organisms that can grow in a variety of environments, such as freshwater, saltwater, and even wastewater. They are used for a wide range of applications, including food and beverage production, biofuels, cosmetics, and pharmaceuticals.

Understanding Algae Dehydration:


Dehydration of algae is typically achieved by exposing the algae to heat or air, which causes the water to evaporate. Various methods of algae dehydration exist, including spray drying, freeze drying, sun drying, and oven drying, but this kind of method has some deduction on the product quality like nutrients, colour, and flavour and is, therefore, suitable for high-efficiency output using the Refractance Window Drying technology. The resulting dehydrated algae can be stored for extended periods of time and is easier to transport and handle than fresh algae. It also has a longer shelf life and is more stable, making it a more convenient form for further processing or use in various applications.

Gemtech Refractance Window Drying (RWD) has several benefits for drying algae, seaweed and carrageenan.

  • Gentle drying process: The Refractance Window Dryer uses low temperatures and infrared radiation to gently dry the algae, seaweed and carrageenan which helps preserve its quality and nutritional value.
  • Efficient drying: The Refractance Window Dryer is highly efficient and can dry algae, seaweed, and carrageenan quickly, which can help reduce energy costs and increase productivity.
  • Consistent drying: The Refractance Window Dryer provides consistent drying conditions, which helps ensure that the algae, seaweed, carrageenan is dried evenly and thoroughly.
  • Reduced risk of contamination: The closed system of the Refractance Window Dryer reduces the risk of contamination from external sources, such as dust or pests.
  • Environmentally friendly: The Refractance Window Dryer uses less energy than traditional drying methods, which can help reduce the carbon footprint of the drying process.
  • Versatile: The Refractance Window Dryer can be used to dry a variety of algae types, including microalgae and macro algae, and can produce dried algae in various forms, such as flakes or powders.
