Main Raw Materials In Liquid Organic Fertilizer Production

More importantly, the raw materials for liquid water-soluble fertilizer fermentation is water (raw liquid). Additionally, liquid organic fertilizer production process relies primarily on the following raw materials after a certain treatment.

  • Firstly, you ought to pay attention to use deep well water or purified water in making liquid fertilizers, and not tap water. Because urban tap water contains disinfectants (such as chlorine) that can inhibit the activity of beneficial microorganisms.

  • Secondly, you need to make solid-liquid separation and filtration from human urine, animal manure (chicken, cow & pig dung), sewage and sludge, industrial wastewater, biogas slurry and other materials.

  • Thirdly, for agricultural production residues, such as soybean meal, soybean residue, rapeseed cake, peanut cake, these need to experience a period of fermentation by compost machines to convert into liquid fertilizer.

  • Furthermore, you can use bone meal, fish meal, animal blood, slaughterhouse leftovers, etc. After harmless treatment, you may need a fermentation enzymatic hydrolysis device to make organic liquid water-soluble fertilizer.

How To Make High-quality Organic Liquid Fertilizer?

If you want to produce high-quality liquid organic fertilizer, the first step is to collect organic raw materials, such as livestock manure and other high moisture organic waste. Secondly, you should carry out pre-treatment, including solid-liquid separation, crushing, and mixing, followed by filtering and disinfecting these liquids. Then, through anaerobic or aerobic fermentation, organic matter can be decomposed  into nutrient rich liquid fertilizers under the action of microorganisms. Finally, after certain blending and packaging, you will get the finished organic liquid fertilizer. Besides, the entire manufacturing process requires strict control of temperature, humidity, and pH values to ensure product quality and fertilizer efficiency. Thus, here are complete liquid organic water-soluble fertilizer manufacturing steps.

Primarily, whether you purchase or use organic matter or wastewater generated by your own farm or factory, it is up to you to choose. For the purchase of powder microbial agents (Bacillus), it costs $15-50 per kilograms for industrial and commercial liquid bio fertilizer production. However, if you determine to make liquid fertilizer from soybean meal, rapeseed cake, peanut cake, animal protein, etc., you have to grind the raw materials by appropriate shredders. Besides, if you want to add nutrient elements like NPK or minerals, you may need our Raymond mill to get super fine powders – the finest size of 0.038mm.

Secondly, you may require a dewatering machine that can separate the original waste like livestock manure and sludge into liquid and solid organic fertilizer. These wastes usually contain high moisture, even more than 85%. Additionally, you can choose to further extract these organic wastewater to obtain liquids with higher purity and concentration. Then, you should build a sedimentation tank to store these high-purity organic liquids. Then, anaerobic fermentation of these raw materials lasts for 2-3 days at normal temperature. When it smells like a sour, alcoholic, and slightly unpleasant odor, anaerobic fermentation process is finished. Of course, if you want to save on the cost of subsequent filtration equipment, you can build a secondary or tertiary sedimentation tank that can settle 10% of the filtered materials.

Thirdly, you need to use filtering equipment to remove suspended solids from the liquid and ensure the purity of the liquid organic fertilizers. This is because liquid fertilizer requires pipeline irrigation to prevent impurities from clogging the nozzle. To be honest, you’s better use water purification devices to remove chlorine from tap water. In addition, if necessary, you need to perform high-temperature or ultraviolet sterilization to kill Escherichia coli and diseased eggs in the organic liquid. Thus, you can extend the shelf life of organic liquid fertilizer. What’s more, at every step of organic liquid fertilizer production, it may be necessary to add such filtering equipment and disinfectors.

More importantly, if you make liquid amino acid fertilizer, you need to first add the composite enzyme preparations to the reactor and heat it up to a constant temperature of 50-60℃ for enzymatic hydrolysis for 3-5 days. Then, the liquid enters fermentation pot for aerobic fermentation. Here, you need to connect an auxiliary material addition tank in parallel. In the later stage of fermentation, you can add liquid or powder microbial agents, molasses, and NPK to add energy to liquid organic fertilizers or make formula fertilizers. Also, you ought to add TE or ETTA chelating agents to make these elemental molecules combine.

In the organic fertilizer fermentation tank, at a constant temperature of 30-50℃, these microorganisms undergo bacterial hydrolysis. If there is no heating device, it takes 4-5 days to complete the fermentation of one tank of liquid fertilizer. However, using our built-in heating fermentation tank, it only takes 3-5 hours. Then, the liquid fertilizer enters the sterilizer, and the highest temperature can reach 70 ℃. Moreover, you need a cooling pot to lower the temperature of the organic liquid fertilizer to room temperature.

Finally, after a series of reactions and adjustments, the organic fertilizer liquid is ultimately transported to the finished product pot for storage. Then, you must avoid light and high temperatures to maintain its activity. Here, you should construct your own lab. After the final quality testing, liquid fertilizer need to meet market standards. Then, due to your budget, you can choose to use directly an automatic filling machine for lower investment. Perhaps, with the sufficient money, you can buy an fully-automatic filling packing production line for bottling, sealing covering and labelling.
