How long does it take to dry seaweed in a dryer

 
Drying kelp requires a well-designed time, temperature, and humidity. How long does it take for a kelp dryer to dry kelp?
 
1. Stage, heating stage: Place the tray filled with materials flat into the oven, without overlapping, to avoid unnecessary air leakage caused by poor placement of the tray. Close the box door and heat the temperature inside the box to 50 ° C;, Heat for 1.5-3 hours, and when there is moisture inside the box, start draining for about 2 minutes. After draining, the temperature inside the box will decrease slightly, and continue heating.

  2. The second stage. Constant speed drying and moisture removal stage: It should be divided into two stages: high humidity and low temperature, and medium humidity and medium temperature. In the high humidity and low temperature range, the temperature should be less than 60 degrees Celsius, with a range of 55 degrees Celsius to 60 degrees Celsius. To avoid color changes caused by high temperature and humidity, observe the changes in water vapor on the surface of the material and remove moisture at any time. This period should be between 3 to 3.5 hours. In the medium humidity and temperature range, with a temperature below 60 degrees and a range of 50 degrees to 60 degrees, the intake valve can be appropriately opened and the return valve can be appropriately closed for moisture removal. Adjustments can be made according to the amount of moisture.
 
  3. The third stage, the deceleration and shaping stage: also known as the low humidity and high temperature stage, this stage has a temperature of 70 ° C~80 ° C, which should not exceed 70 ° C in the early stage and 80 ° C in the later stage.
