In 2022, a Korean customer purchased a 1.5-2 ton abalone feed production line. Now the production line has been put into use. The returned 2-ton abalone feed production line has also arrived at the customer's factory, and the new production line is being installed and debugged. By the end of this year, it is expected to place an order for a 3-ton shrimp feed production line.

Expanded and precipitated granular feed is easy to absorb water and soften, suitable for gnawing, and can also reduce the loss of debris generated during gnawing, reducing feed waste and water pollution. Moreover, the expanded feed has a long water resistance time and a high degree of maturation. Twin screw wet puffing machines are commonly used for producing puffed feed.
