(1) The automatic batch pre-expander has a PLC and touching screen and panel which enables fully automatic production cycle of material filling, electronic weighing, chamber temperature, pressure and material position measuring by a sensor.
(2) It uses an electronic weigh system and position sensor to control raw material volumes and expanded density, while ensuring density tolerances within 3%.
(3) With the adoption of German comparison valve (installed additionally according to the customer's demands) and Japanese decompression valve to control the temperature and steam pressure in the chamber, which can guarantee the stability of the pressure in the decompression valve exit, thus the temperature tolerance is controlled within 1%; also guaranteed the consistency of the emanated material of EPS and prevent becoming agglomeration because of the temperature.
(4) Adoptions of automatic material filling by pressurizing and electronic weighing system combining with material position switch enlarge the productivity and save labor.
(5) Closed chamber keeps a constant pressure that brings about efficient heating so as to save up by 50% steam compared to continuous pre-expander.
(6) With a closed efficient drying system in the expansion chamber, material can be dried in the chamber rather than going through a long fluidized bed.
(7) The machine has a fully automatic production cycle which concludes filling, expansion, sieving, de-lumping and transportation to silo.
(8) Electric appliance, power components, the valves etc. are local well-known brands, thus guarantee the machine operating stability, reliable and longevity.
(9) Expanded material is discharged fast with a back pressure from compressed air.
(10) The computer has a memory function that can memorize the former EPS material producing factory, its number, specification, expanding process and all the parameters. When the EPS material is needed in the production, the only work needed is pointing the touching screen.
(11) The electronic scale is installed above the chamber, and the drying process is done in the chamber, so it occupies a smaller area.
(12) The machine is suitable in the plateau area, too, which indicates the superior of batch pre-expander (under the same condition, the continuous pre-expander has a extremely low efficiency).
