By using the liquid biofertilizer production technology, you can efficiently make liquid biofertilizer from fish waste. It needs to crush, sterilize, chelation filtration, adding microbial agent. You can get more details below. YUSHUNXIN has the fish waste bio liquid fertilizer making line, welcome to consult!
Step1: Crushing fish waste into fine powder for liquid biofertilizer production
First, use a double-shaft shredder to crush fish bones, fish meal, and fish slaughterhouse scraps into fine powder. This makes it easier to fully contact with water and other additives. It can accelerate the enzymatic hydrolysis and fermentation process. YUSHUNXIN equips the double-shaft crusher with high-strength stainless steel blades. It can easily crush hard materials.
Step2:Adding water and sterilizing for getting safety bio liquid fertilizer:
Then, add water to the crushed fish paste in proportion. The amount of water is preferably 5 times that of the fish paste. At the same time, in order to ensure the quality of the liquid biological fertilizer, it must be sterilized to eliminate harmful microorganisms contained in the liquid. Sterilization and disinfection are mostly in high-temperature. So you need to temporary storage and cooling.
Step3: Chelation filtration to obtain high-quality liquid biological fertilizer
Then there is an enzymatic hydrolysis and fermentation process that lasts for 3-5 days. Enzymatic hydrolysis can effectively reduce the difficult-to-decompose organic matter in the raw materials, which is beneficial to improve the purity and quality of fish protein liquid fertilizer. Then filter out the impurities to obtain a pure liquid. YUSHUNXIN‘s chelating tank integrates fermentation and filtration, which can increase its speed.
Step4 : Cooling and adding microbial agents:
You still need to cool the liquid after enzymatic hydrolysis. Then, please add microbial strains and elements with different functions according to your needs to make fish protein liquid biofertilizer with different effects. Common microbial agents include compound Bacillus, compound enzyme preparations and other beneficial microbial flora.
Finally, use a fully automatic filling machine to package it into fish protein biofertilizer of different specifications for sale.
Tips :
If the liquid biofertilizer after enzymatic hydrolysis has foam or is not viscous enough, you can add honey, maltose, brown sugar, and emulsifier to increase the viscosity of the liquid.
The above is the whole process to make liquid biofertilizer from fish waste. In addition, you can also make animal manure liquid biofertilizer or liquid NPK biological fertilizer. If you need it, please consult us!
