Detailed description are as follows:
A method of lactic acid being produced using agriculture and forestry organic waste material, is included the steps that from agriculture and forestry organic waste material decomposition and separation cellulose
With the step of producing lactic acid as raw material using the cellulose that decomposites, the step of agriculture and forestry organic waste material decomposition and separation cellulose, passes through
Agriculture and forestry organic waste material skid module formula composition decomposition and separation equipment realizes, detailed process are as follows:
1) material primary breakup process, it is radial into material primary breakup device by the material simply cut, pass through crushing
Mechanism crushes, which is completed jointly by set of blades and the ridge on vertical cylinder inboard wall, and then material sinking reaches powder
The inclined-plane of broken room bottom, which enters, beats room, completes further being crushed for material, and material constantly passes through hammering, squeezes, broken to become smaller,
Then exit baffle, sieve are poured into, beats room until being less than screen size and being just discharged, into sonication chamber, ultrasonic vibration makes
