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.
Fused Silica features high transmission from 200nm to 2.2μm with a low coefficient of thermal expansion, making it ideal for the most demanding ball lens applications in the ultraviolet, visible, and near infrared spectra. Ball lenses are commonly used for improving signal coupling between fibers, emitters, and detectors, as well as objective lenses in endoscopy and bar-code scanning applications. Half-ball lenses simplify handling and integration.Half ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy,microscopy,optical pick-up devices and laser interferometry and measurement.
