Preparation device of leaf surface blocking and controlling agent

The utility model relates to a preparation device for a leaf surface blocking and controlling agent, and belongs to the technical field of blocking and controlling agent preparation equipment. Comprising a fermentation tank, an elevator, a batching tank, a filtering partition plate and a sealing plate, different raw materials are mixed in the fermentation tank and then fermented, fermentation obtained after fermentation is filtered through the filtering partition plate and then guided into the bottom of the fermentation tank to be temporarily stored, then quantitative fermentation liquor is guided into the batching tank to be subjected to batching again, and therefore the blocking and controlling agent is prepared. Biological fermentation and configuration are connected into a whole, so that the processes of production, re-drying, packaging, transportation, re-dissolution and the like of a biological fermentation product are shortened, the production cost of the leaf surface blocking and controlling agent is
