Features: 1) Uses PLC programmable controller and touch screen to realize man-machine dialog 2) Uses charging device of automatic negative pressure, electric weighing, and level switch to realize automatic feeding and gauge 3) Uses auto-controller of temperature and pressure in the chamber and photoelectric level material to realize the uniform and light density of the beads 4) EPS beads is formed in the auto-cycle by shock sieve, crushing and transportation fan 5) Uses imported steam reducing valve and proportional valve (optional) to ensure the stable pressure of the reducing valve outlet, and the temperature tolerances within ?? in the chamber. If the block density is above 30kg/m? the proportional valve should be installed 6) Hot air drying system (patented) in the fluidized beds with temperature up to 75? ensures the EPS raw material drying and fast molding, speeds up the aging process and shortens the production cycle 7) Separation of auto-charging device and electric weighing with the machine avoids the inaccuracy and unreliability of electric weighing caused by operation 8) Four security devices on the machine ensure that it operates normally and safely 9) For production technical memory and quantity statistic, operator can find the foam parameter of manufacturer's used EPS raw material and simultaneously set the different foam parameter by themselves 10) For statistics and account of EPS production per day, week, month or year, the electric weighing can be installed with digital printer optionally 11) Remote communication system can be optionally used to monitor the machine and remedy its faults 12) Software system can be upgraded to improve its processing properties 13) Uses new EPS foam processing technology to improve its production efficiency, which ensures that EPS beads foam more accurately, lightly, fast and have low fault rate during its secure operation
