AI Technical Summary
Problems solved by technology
 The main raw materials are water hyacinth, dehydrated sludge, microbial agents, rice bran or peanut shells, heavy metal deactivators, etc. Specific description of the processing process according to the process flow:
 After the water hyacinth is squeezed, dehydrated and crushed, it is mixed with dehydrated sludge, microbial inoculants, heavy metal deactivators, rice bran or peanut hulls for fermentation and aging (secondary fermentation), and the decomposed clinker after fermentation aging A certain amount of humic acid and urea are mixed and processed into commercial organic fertilizer.
 (1) Water hyacinth dehydration
 Extrusion dehydration reduces the moisture content from 95% to about 50%.
 (2) Water hyacinth crushed
 Due to the high water content of water hyacinth, a professional grinder must be used to avoid damage to the motor; the fineness is about 3cm, so it does not need to be too precise.
