On the stage of organic fertilizer production, the compost turning machine acts like a masterful “iron chef”, meticulously controlling each fermentation step to “cook” various organic wastes into nutrient-rich compost. Let’s explore this “chef’s” secret recipe.
Step 1: Meticulous Ingredient Preparation
Like a chef preparing ingredients, raw materials first undergo crushing and screening to remove impurities, achieving the “golden size” of 2-5 cm particles. The carbon-nitrogen ratio (25-30:1) and moisture content (50%-60%) are adjusted—the perfect formula for microbial activity. Too wet? Add straw “absorbent”. Too dry? Add water for “seasoning”.
Step 2: Scientific Layering in Trough
Pre-treated materials are evenly spread in fermentation troughs at 0.8-1.5m depth—this “fermentation bed” thickness ensures sufficient heat generation without compromising ventilation. Like baking a cake in the right pan, this thickness is the “gold standard” from years of practice.
Step 3: Precise Temperature-controlled Turning
When material temperature reaches 60-70°C, the “iron chef” begins work. Its turning teeth act like chef’s spoons, flipping and mixing materials so every part can “breathe”. This phase resembles slow cooking, with turning every 1-3 days over 15-30 days, allowing microbes to fully “cook” the organics.
Step 4: Maturity Assessment and Harvest
When temperature drops to ambient level and materials turn dark brown with earthy fragrance, this “organic feast” is ready. The material becomes loose, odor-free, with pathogens eliminated by heat, ready for further “processing”.
Why Choose This “Iron Chef”?
• High Efficiency: 30%-50% faster than manual methods
• Superior Quality: Even turning ensures perfect “doneness”
• Labor-saving: Automated operation reduces workforce
• Eco-friendly: Minimizes odor and energy consumption
• Versatile: Handles diverse “ingredients” from manure to straw
In the kitchen of circular agriculture, compost turning machines are using their “culinary art” to transform waste into “black gold”, providing continuous nutrition for green farming.
