Making commercial organic fertilizer with furfural residue

 As a waste generated in the process of biomass hydrolysis, furfural residue has high salt content and is acidic, and its massive accumulation will pollute the atmosphere, soil and river. As a kind of biomass waste, furfural residue contains a large amount of cellulose, hemicellulose and lignin, and has good recycling value. Therefore, how to rationally utilize the furfural slag to eliminate its environmental pollution, increase the economic added value of furfural slag, achieve the goal of zero emission of pollutants in the production process of furfural enterprises, and achieve the purpose of clean production and recycling. The problem of resource utilization of furfural slag needs to be solved.

Furfural slag has the effect of improving soil aggregate structure, improving saline-alkali land and increasing soil organic matter content, which can participate in the production of animal manure organic fertilizer.

The production process of furfural residue bio-organic fertilizer uses less steam, which can reduce the investment of water treatment system and steam. The main raw materials of this organic fertilizer production line are furfural residue and animal waste. These two sources are very extensive, we can obtain materials from local sources reduce the transportation cost of materials; the granulation by organic fertilizer granulator is also obvious to all, which can improve crop quality, improve fertilizer utilization, and improve soil environment.

In the organic fertilizer production line, the first step is fermenting compost, and it is necessary to ferment all raw materials such as furfural residue and animal manure.

First, the raw material moisture should be controlled at about 70%. If there is less water in the raw material, it should be poured and wetted with water to ensure proper water. At the end of the fermentation, other agricultural machinery and equipment, such as a pulverizer, a mixer, a granulator, etc., are used to produce organic fertilizer granules.

The composting process is mainly carried out by the action of microorganisms, which are the main body of composting fermentation. There are two sources of microbes involved in composting: one is the large number of microorganisms in the organic waste; the other is the artificially added microbial inoculants. These strains have strong decomposition ability to certain organic waste under certain conditions, and have the characteristics of strong activity, fast propagation, rapid decomposition of organic matter, etc., which can accelerate the progress of composting reaction and shorten the time of composting reaction.

Based on years of production experience, our company has developed a series of compost turning machines. During the fermentation process, the materials are turned over, the ventilation and oxygen volume are increased, and the fermentation time can be greatly shortened.
