Automatic Food Waste Organic Fertilizer Treatment Production Line

Product Description

Food waste, also known as drowning water, food residues, food and kitchen residues, etc. Now people's awareness of environmental protection has increased. The disposal of food waste has always been a concern for people. The content of organic matter in food waste is high, about more than 95% of dry matter. It is easy to corrupt and stink, and breed bacteria, causing the disease to spread. Especially in the summer, secondary pollution can easily occur during collection and transportation. However, in addition to the high content of organic matter in food and kitchen waste, it is also rich in protein, nitrogen, phosphorus, potassium, calcium, and various trace elements. It has the characteristics of complete nutrition elements and high recycling value. Jiutian Company's use of food waste as a comprehensive utilization of resources not only avoids resource waste but also makes the resources reused and turns waste into treasure.

There are three main paths for comprehensive utilization of kitchen waste resources. The first is protein feed made from kitchen waste. The kitchen waste is sorted, removes impurities, crushes, dehydrates, deoils, recovers oil, produces biomass diesel, and then adds yeast, probiotics and auxiliary materials, undergoes aerobic fermentation, drying, cooling, packaging, and waste water and waste gas pass through. The final products are protein feed and biomass diesel after treatment of up-to-standard emissions; the second is organic fertilizer made from kitchen waste. The kitchen waste is sorted, removes impurities, crushes, dehydrates, deoils, recovers oil, produces biomass diesel, and then adds yeast, enzyme preparations and auxiliary materials, undergoes aerobic fermentation, drying, cooling, packaging, and waste water and waste gas pass through The final products are organic fertilizer and biomass diesel; the third is to make biogas from kitchen waste. The kitchen waste is sorted to remove impurities, pulverize, deoil, recover oil, and then add anaerobic bacteria material. In a sealed tank, anaerobic fermentation is performed to produce biogas, which is used for power generation or combustion. The waste residue is dehydrated, Organic fertilizers are produced by drying, cooling and packaging. The wastewater is treated and discharged up to the standard. The final products are biogas, organic fertilizers and biomass diesel.

Project Feature

(1) Food waste treatment equipment innovation: The process of food waste to regenerate protein feed, regenerating fats, fermented biological feed, and organic fertilizer, which is based on the economic value of food waste. In the same production line, through the physical, Comprehensive technical classification, extraction and processing of machinery, biology, and other products with different economic values such as protein feeds, oils and fats, fermented biological feeds, biogas, and organic fertilizers, which is high economic efficiency, using the new ideas and processes of food waste to developing the new resources.

(2) Kitchen waste treatment equipment innovation: There are many sundries in the food waste, the components are complex and unstable, and the oil content is high. Therefore, the key equipment in the complete set of equipment is the special equipment after the innovation and transformation. The complete set of equipment is fully sealed and automatically system and the central program control system. It realizes the continuous, automated, and large-scale reprocessing and utilization of food waste.

(3) Renewed product innovation: The food and kitchen waste need to classification and extraction, and the simultaneous production of protein feeds, oils, fermented biological feeds, fermented organic fertilizers, biogas, etc. Now it is international mainstream. The protein content is 32-37% in renewable protein feed. Regenerative fat is a chemical raw material. Regeneration of fermented biological feed is made by changing the feed filling material to make various new types of feed, regenerating fermented organic fertilizer, nitrogen, phosphorus and potassium, and rich in plant nutritive elements. Anaerobic fermentation to produce the biogas, a full-depth use of food waste nutrients, this kitchen waste resources can be 100% recycling.

Working Principle

Material Flow: the raw material with 75-85% moisture will be sent into the dewatering machine, and then the moisture will be reduced to 60-65%, then feed into the dryer by screw conveyor, concurrent flow drying. Under the effect of the inner shoveling plate, materials are taken and scattered constantly, and move in the spiral forward method. Through three layers (inner, middle, and outer layer), heat exchange is realized between material and hot air medium. The materials that achieve the drying effect move forward fast and are discharged out of the roller. Wet materials that still don't achieve the drying effect couldn't move fast due to self-weight and are dried completely during the controlling route, thus achieving the drying effect. After the whole drying process is completed, materials are discharged by a screw conveyor. The final moisture will be reduced to 14-18% (can be adjusted according to the buyer's requirement). there is a special device inside the dryer, that can prevent the unequal drying of materials.
Air Flow: through the hot blast stove and air blower inflating, the air enters the hot blast stove for combustion heating. Its temperature reaches up to 600-850ºC, then it is inhaled by the dryer-induced draft fan to dry material and evaporate water. When the temperature decreases to 55-60ºC, it is discharged out of the dryer. Wet air containing dust is discharged on standard through dust remover purifying.
