When anaerobic fermentation of food waste was used to produce biogas, it was found that if the cellulose content of the material was high and the degradability was small, reducing the particle volume of the material by chopping could increase its gas production, speed up the digestion rate and reduce the digestion volume. Typically, gas production can be increased by 10% to 20%.
Shredded kitchen waste
Although reducing the particle size of organic solids can significantly promote anaerobic digestion, it is not the smaller the better. Within a certain particle size range, the improvement of biogas potential has nothing to do with the smaller particle size of the material. When the particle size was between 5 and 20 mm, reducing the particle size could not significantly increase the gas production. Therefore, the crushed material size of the industrial food waste shredder biogas should be controlled within 5~20mm, so what shredder machine is used to produce biogas? Today I recommend such a device to everyone.
Food waste anaerobic fermentation to produce biogas crusher equipment recommendation
GDF food waste dual-shaft shredder is a shredder equipment specially developed and designed for the characteristics of food waste. The equipment has strong material adaptability and is not limited by moisture. Waste oils, raw meat residues, leftovers, bones, lunch boxes and other food wastes are pretreated by shearing and shredding, which lays the foundation for improving the disposal efficiency of the subsequent biogas production process. Let us see the advantages of GDF series food waste shredder:
- The bearing is designed with multiple seals to adapt to the wet and oily environment.
- Intelligent system control, multiple intelligent monitoring and protection, to ensure the smooth operation of the equipment.
- High-alloy tool with long service life and good interchangeability.
- The spindle has been heat treated for many times and processed with high precision, and has strong anti-fatigue and impact resistance.
- The key components are made of 304 stainless steel with long service life.
At present, the treatment methods of changing the particle size of materials by mechanical shredding and grinding almost exist in the pretreatment stage of many anaerobic digestion processes. In this way, choosing a suitable industrial food waste shredder biogas can greatly improve the efficiency of the entire production line. GEP ECOTECH has been focusing on the manufacture of food waste shredding equipment for many years. It has rich project experience and has been well received by domestic and foreign customers.
