This invention discloses a high-temperature aerobic fermentation fertilizer made from livestock and poultry manure and straw suitable for saline-alkali land, and its preparation method, relating to the field of mixed fertilizer technology. The apparatus for preparing this high-temperature aerobic fermentation fertilizer made from livestock and poultry manure and straw suitable for saline-alkali land includes a fermentation drum. A feed cover is movably connected inside the fermentation drum, and a discharge cover is movably connected to the outer wall of the fermentation drum. A feed cover is fixedly connected to the right side of the fermentation drum. The method for preparing this high-temperature aerobic fermentation fertilizer made from livestock and poultry manure and straw suitable for saline-alkali land involves rotating the fermentation drum around a fixed axis, turning over the internal pile. An inner convex plate scoops up the bottom pile material and then throws the corresponding pile material downwards, dispersing the bottom pile material onto the top. This allows the pile to maintain a more even temperature during fermentation, resulting in higher microbial activity and significantly improved fermentation efficiency.

The utility model discloses a tomato juice evaporation concentration system, the outlet of tomato juice raw solution pipe is connected with the top feed inlet of primary falling film evaporator through feed pump, the cold side of condensate water preheater, and the bottom outlet of primary falling film evaporator and its separator is connected with the top feed inlet of primary falling film evaporator through primary falling film circulating pump, the inlet of primary falling film circulating pump still links through primary falling film discharge pump, TVR circulating pump, the pipe of secondary forced evaporator with the lateral wall inlet of secondary forced separator, and the bottom outlet of secondary forced separator is circulated through TVR circulating pump, still links through secondary discharge pump and tomato juice concentrated liquid discharge pipe, and the secondary steam export of primary falling film separator is connected with the shell course inlet of primary falling film evaporator through steam compressor, and the secondary steam export of secondary forced separator is connected with the shell course inlet of secondary forced evaporator through steam jet pump. The system has high heat utilization rate, and the capacity is big, reduces the density fluctuation of discharge while reducing energy consumption.
