Method for preparing biomass fuel by utilizing processing residua of cassava

Abstract

The invention belongs to the field of the preparation of biomass fuel, and in particular relates to a method for preparing biomass fuel by utilizing processing residua of cassava. The method comprises the following steps of: dehydrating the processing residua of the cassava until the content of moisture is between 50 and 70 percent, and drying until the content of the moisture is below 45 percent to obtain the biomass fuel. According to method, the processing residua of the cassava can be used as the biomass fuel, and a technical path for realizing the purpose, namely the processing residua of the cassava can be used as the biomass fuel, industrially on a large scale is provided to point out a direction for solving the problem of pollution regulation of the processing residua of the cassava fundamentally, so by the method, environmental pollution can be avoided effectively, the resource development and utilization of waste residues are realized, and obvious economic and social benefits are produced.

Description

technical field [0001] The invention belongs to the technical field of biomass fuel preparation, and in particular relates to a method for preparing biomass fuel by using cassava processing residues. Background technique [0002] In the south of my country and South Asia and ASEAN countries, cassava is one of the most important raw materials for the production of starch and alcohol. After processing cassava to produce starch or (and) alcohol, there are still a lot of residues. A medium-sized or larger scale uses cassava as raw material to produce starch. Or (and) alcohol companies will produce tens of thousands of tons or even hundreds of thousands of tons of processing residues every year. According to preliminary estimates released by relevant departments, the total amount of cassava processing residues produced in my country every year is at least seven to eight million tons, and it is still increasing at a relatively rapid rate. [0003] Cassava processing residues also ...

AI Technical Summary

Problems solved by technology

But because cassava starch or (and) alcohol production enterprise produces the cassava processing residue moisture content is higher, generally all can be between 85-90%, even higher, can't be directly used as fuel combustion at all, and there is not comparatively mature yet in addition at present It is feasible and can be industrialized and scaled to process it into other economical products or raw materials. Only a small part of cassava starch residue and distiller's residue in all cassava processing residues are transported away by farmers near the enterprise during the production season As fresh feed, most of them cannot be processed and utilized in time, not to mention synchronous processing with starch or alcohol production, resulting in processing residues such as cassava starch residues or (and) distiller’s grains residues that can only be discharged to storage If it is stored in the pool or piled up in the yard, if it is stored for a long time, it will deteriorate and give off a foul smell, and at the same time breed a large number of mosquitoes and flies, which will not only seriously pollute the environment, but also cause a great waste of resources.
