The important bottleneck that restriction organic resources are utilized.Especially for China in face of the present situation of energy shortage, efficiently it is dehydrated into urgently
A big technical barrier to be solved.Most of high-moisture percentage organic matters are all the residues that discarded object and fermentation leave, and are dehydrated
Organic matter afterwards can not only reduce the foul smell produced after discarded object fermentation to the discharge capacity of environment, can also effectively be used
Turn waste into wealth, but simple utilization heat dried biomass does not only result in the waste of the energy, also results in high-moisture percentage organic
The thing loss of energy and the inside physical property material modification in itself.
Because high-moisture percentage organic matter often contains a large amount of cytoplasm and colloidal substance, these materials have firm water holding
Structure, thus results in organics dehydration difficulty, and being dehydrated by common mechanical can only be down to 80% or so by moisture content.Further drop
Low-water-content generally uses heating power desiccation method, i.e., its moisture evaporation is reduced moisture content by heating high-moisture percentage organic matter.
Although the characteristics of heating power desiccation method has technique and ripe equipment, can consume mass energy, operating cost in this way
It is higher.In order to solve these problems, hydro-thermal desiccation method treatment technology is increasingly paid close attention to by people.The core of the method is to make
The organic matter of high-moisture percentage is heated with hydro-thermal reaction device, and destroys the water holding structure of organic matter at a certain temperature, so as to carry
The dehydration rate of high-moisture percentage organic matter high.But the high-pressure hydrothermal reaction kettle for using at present is difficult in liquid form to High water cut
