Xinxiang Yinheng Machinery & Electrical Co., Ltd. is a leading manufacturer of bio-organic fertilizer equipment and TMR feed mixers. The Yinheng organic fertilizer fermentation tanks utilize complete aerobic reactions to process human and animal excrement (including cow dung, sheep dung, pig dung, chicken dung, etc.), kitchen waste, straw, rotten vegetables, plant waste, sludge, and more, making them suitable for a wide range of locations such as residential complexes, canteens, gardens, markets, and farms. They operate continuously with low environmental impact, no odor during production, high automation, low power consumption, and can completely kill worm eggs and pathogenic bacteria. They are climate-independent, allowing for 365-day continuous operation, offering significant economic benefits to manufacturers and farms. The fermentation tanks maintain a constant high temperature of 60 to 65 degrees Celsius, with continuous oxygen supply to sustain aerobic reactions. After a 72-hour high-temperature reaction, the organic matter in the cow dung is composted, and various pathogens are eliminated. The resulting powdered organic fertilizer is used for orchard, tea plantation, and vegetable farming, transforming waste into valuable resources and generating substantial economic returns while achieving complete pollution control. The fermentation tanks effectively mix raw materials in a closed space, adding 200 kg of wood chips (or an equivalent proportion of straw, garden waste, etc.) per ton of excrement for biological fermentation. The tanks integrate traditional composting processes like compost pits, fermentation, turning, and discharge, offering three to four times the efficiency of traditional fermentation methods, reducing processing time by five times, and are unaffected by temperature, making them applicable in cold regions. The fermentation tanks are made of 20# steel plates, with drum plates measuring 14mm thick and a diameter of 2.8*12m, powered by two 3KW motors. They can produce 8-10 tons of finished organic fertilizer per day. The entire equipment occupies approximately 1,000 square meters, allowing for cost recovery within the same year of investment.
