Embodiment 1
[0040] Embodiment 1, production biological fermentation nitrogen and potassium compound fertilizer (N15-K5)
[0041] Concentrate the glutamic acid fermentation waste liquid after extracting bacterial protein to more than 27 Baume with four-effect evaporation concentration equipment, and the solid content is about 40%. Dissolve 48kg of potassium chloride in 107kg of unconcentrated extracted bacterial protein A saturated solution was prepared from glutamic acid fermentation waste liquid, and the saturated solution was mixed with 1000 kg of concentrated fermentation waste liquid to obtain a mixed solution. The solution is sprayed into the spray fluidized granulation equipment through high-pressure air and a spray gun installed in an appropriate position. The air inlet temperature of the main machine of the granulation equipment is 175°C, the temperature of the fluidized bed material layer is 94°C~98°C, and the pressure of the spray gun is 0.22MPa. By adjusting the frequency of th...
