Problems solved by technology

[0004] 1. The protein powder production process adopts vacuum concentration and needs heating, spray drying requires high solid content, requires special equipment, is easy to stick to the wall and clogs, high energy consumption, and long production time
[0005] 2. The waste after extraction of animal biochemical products is only a single protein powder production and utilization, with backward technology, single product and low added value
[0006] 3. The waste liquid is not classified and treated, only the macromolecular protein is recovered, but the most valuable small molecular protein peptide is discharged, the utilization rate is low, and the economic benefit is poor
[0007] 4. The treated wastewater still contains a large amount of organic matter such as small molecular proteins and sodium chloride, which does not meet the requirements for water recycling and pollutes the environment. At the same time, the final water reuse has not been realized, wasting water resources
