The selection of low-value small fish, small shrimp, or processed fish fillets, fish heads, tails, clams, internal organs, etc. during the canned fish can be used as raw materials for processing fishmeal. However, salted raw materials should not be used.
Cooking removes dirt and impurities from the raw materials, rinses them with water, removes them, drains them, put them into a bag, put them in a steamer or cook with water for about 20 minutes.
Press out the cloth and add stones or other heavy objects to the water. If the quantity is large, mechanical pressing can be used, and the starting pressure is small. After most of the water is squeezed out, the pressure is gradually increased until it is dried.
When drying, often flip, let the water content below 12%, to avoid decay and deterioration.
Composite Geomembrane is a new type of anti-seepage material made by infrared ray heat with Geotextile(PET) and Geomembrane (PE .)
