In the past, crop straws were usually piled up randomly in the fields or in front of houses, which was not only unsanitary, but also a great potential safety hazard. In recent years, due to the high-pressure situation of straw burning ban policy and the support of government departments at all levels to encourage straw returning to the field, most farmers are “forced” to simply crush straw and directly return it to the field. Through years of practice, the drawbacks of straw returning to the field have already begun to emerge: the residual pest sources on the straw cause the outbreak of pests and diseases in the next crop, the straw decomposes slowly in the soil, and the decomposition process competes with the crops for fertilizer and oxygen, resulting in grain yield reduction, etc., which are frequently reported in newspapers.

In the process of building new countryside, straw also needs new treatment methods, and the emergence of straw briquette machine has solved this problem. The straw briquette machine(or we call it straw briquetting machine) is used to process the straw into high-density blocks, and its compression ratio can reach 1/5-1/15, which can greatly reduce the transportation and storage space. If used with drying equipment, fresh straw can be pressed.

The emergence of straw briquetting machine has greatly improved the utilization rate of straw, and promoted the energy and feed utilization of straw.

1.Straw energy conversion

Energy utilization of straw Energy utilization of straw is an important starting point to improve the comprehensive utilization rate of straw, an important way to supply clean energy in rural areas, and an effective means to solve outstanding environmental problems. In recent years, our government attaches great importance to and actively promotes the rapid development of biomass energy utilization and related industries. The Guiding Opinions on the Construction of Straw Gasification Clean Energy Utilization Project issued at the end of 2017 pointed out that by 2020, a number of straw gasification clean energy utilization implementation counties will be built, and the comprehensive utilization rate of straw in the implementation areas will reach more than 85%, effectively replacing loose coal in rural areas, and supplying clean gas for cooking, heating and other public facilities such as rural schools, hospitals and nursing homes for farmers. Biomass briquettes produced by straw briquetting machine has the characteristics of high calorific value and less harmful gas emissions. The briquetting produced by biomass briquetting machine can relieve the energy pressure and reduce the consumption of non-renewable energy such as coal, oil and natural gas.

2.Straw feed conversion

Straw has high nutritional value, and the organic matter in the body accounts for half of crops, so it can be used as livestock feed. However, there are a lot of indigestible lignin, cellulose, hemicellulose and other substances in the straw. Eating it directly as feed will not only produce a serious rough feeling, but also be detrimental to livestock digestion. In order to meet the growth needs of livestock, people can treat straw by physical treatment, chemical treatment and microbial fermentation. Straw briquetting machine uses physical treatment to treat straw. Straw and forage are pressed into high-density cakes by straw briquetting machine, and the compression ratio can reach 1:5 or even 1:15. This can greatly reduce the transportation and storage space. If it is used with drying equipment, it can suppress fresh grass, keep its nutritional components unchanged and prevent mildew. High-density feeding cake can achieve great economic benefits in daily feeding and commercial feed production.

Biomass briquetting machine is a good equipment to turn straw into energy, which can effectively solve the problems of straw waste and secondary pollution. With the help of biomass briquetting equipment, turning straw into energy is a good way to get rich with low cost, economic benefits, social benefits and environmental benefits.
