With the advancement of organic agriculture development, fish protein liquid fertilizer has become an important choice in modern agriculture due to its rich organic nutrients and environmental friendly characteristics. Through efficient production process and professional equipment, fish farming waste is transformed into high value liquid fertilizer, which not only reduces environmental pollution, but also provides a high quality nutrient source for agricultural production. This article will provide you with a detailed analysis of the fish protein liquid fertilizer production machine and its process, to help enterprises optimize the production line.
The main raw materials of fish protein liquid fertilizer include:
Fish farming waste: such as fish viscera, fish scales, fish bones, sludge, etc.
Organic supplementary materials: such as molasses, whey, etc.
Microbial fermentation strains: such as lactic acid bacteria, yeast, Bacillus subtilis, etc.
These wastes can be efficiently transformed into liquid fertilizers rich in nitrogen, amino acids and a variety of trace elements after scientific treatment.
The production of fish protein liquid fertilizer is mainly divided into six major process steps:
1. Raw material processing
Core equipment: pulverizer, mixer.
Process description:
Collect fish waste and clean it to remove sediment and impurities.
Use the pulverizer to crush the waste into small pieces to increase the specific surface area and provide conditions for subsequent fermentation.
The mixer is used to mix the fish waste with water in proportion to prepare a homogeneous slurry.
2. Fermentation treatment
Core equipment: stainless steel fermenter, temperature control device.
Process description:
Add the mixed slurry into the fermenter, add microbial strains (or protease).
Control the temperature of the fermenter at 30-50℃ and set the fermentation time (7-15 days).
Stirring system ensures uniform fermentation and effective decomposition of protein into amino acids and other nutrients.
3. Filtration and separation
Core equipment: plate and frame filter or screen filter.
Process description:
After the fermentation is completed, the solid residue is separated from the liquid by filtering equipment.
The liquid part is used as the raw liquid of fish protein liquid fertilizer, and the solid residue can be further used as compost.
4. Blending and Finishing
Core equipment: liquid mixing tank, pH adjustment device.
Process description:
Add inorganic fertilizers such as nitrogen, phosphorus and potassium in the mixing tank to enhance the nutrient content of the fertilizer.
Adjust the pH to between 6-7 to ensure that it is suitable for crop absorption.
Add preservatives (such as potassium sorbate) to extend the shelf life of the product.
5. Filling and Packaging
Core equipment: liquid filling machine.
Process description:
Fill the mixed liquid fertilizer into plastic drums or bottles through the filling machine.
Sealing and labeling are done automatically for easy storage and transportation.
6. Waste gas and sewage treatment
Core equipment: exhaust gas treatment device, sewage treatment equipment.
Process description:
The gas produced in the fermentation process is passed through the exhaust gas treatment device to remove the odor.
Cleaning wastewater is discharged through sewage treatment equipment to ensure environmental protection.
1. High efficiency and environmental protection
The whole fish protein liquid fertilizer production machine is sealed to avoid odor leakage.
Waste resource utilization, reduce environmental pollution.
2. High degree of automation
From raw material processing to packaging can realize automatic control, reduce manual intervention.
PLC system can monitor the temperature, time, pH and other key parameters in real time.
3. Strong adaptability
The fish protein liquid fertilizer production machine configuration can be adjusted according to different raw materials and demands, with high flexibility.
The fish protein liquid fertilizer production machine production scale can be customized from small pilot line to large industrial line.
4. Excellent product quality
The fish protein liquid fertilizer production machine is made of food-grade stainless steel, which ensures the hygiene and safety of the production process.
The output of liquid fertilizer is rich in nutrients and has high absorption efficiency.
The application of fish protein liquid fertilizer in agriculture is becoming more and more extensive, mainly as follows:
Economic crops: such as fruits, vegetables, tea and other high value-added crops.
Field crops: such as rice, wheat, corn and other food crops.
Horticulture and greening: to provide high quality nutrition for garden plants and lawns.
The increase in global demand for green agriculture has made fish protein liquid fertilizer a hot spot in the market. Through efficient fish protein liquid fertilizer production machine, companies can not only improve production efficiency, but also seize the opportunity of green development.
The process of fish protein liquid fertilizer production machine not only realizes the resourcefulness of waste, but also provides an environmentally friendly and efficient solution for agriculture. In the context of the global agricultural transformation to green and sustainable development, investing in fish protein liquid fertilizer production equipment will be a wise choice.
