Step 5: chelating liquid is placed in cooling and stirring device, adds the wilkinite of predetermined dose 006; When in cooling and stirring device, induction module senses that weight >=preset value 002 put into by raw material, to PLC transmitting digital signals 102; PLC receives numerary signal 102, transmits executive signal 801 to refrigerating module, transmits executive signal 802 to stirring module simultaneously; Described refrigerating module receives executive signal 801, by chelating liquid refrigeration to predetermined temperature value 001; Described stirring module receives executive signal 802, by the raw material stirring scheduled time 001;
Step 6: after completing, is placed in drying installation by gained material, when the induction module in drying installation senses that weight >=preset value 003 put into by raw material, to PLC transmitting digital signals 103; PLC receives numerary signal 103, transmits executive signal 803 to irradiation modules, and described irradiation modules receives executive signal 803, opens the drying installation scheduled time 02, raw material is carried out drying;
Step 7: dried material is placed in shredding unit, when the induction module in shredding unit senses that weight >=preset value 004 put into by raw material, to PLC transmitting digital signals 104; Described PLC receives numerary signal 104, transmits executive signal 804 to shredding unit; Described pulverizing module receives executive signal 804, opens shredding unit, by the raw material pulverizing scheduled time 03.
