General plastics have hygroscopicity, can absorb the moisture in air, and different materials contains certain amount of moisture.Described plastics be by feed particulate material put into injection or single lead screw ex truding briquetting machine after hot briquetting be required plastic products.If during using injection or single lead screw ex truding briquetting machine to be shaped to finished product, plastic raw materials contained humidity is too much, then plastic raw materials is susceptible to hydrolysis, or raw material itself dies down and reduces plastic product intensity or toughness after shaping.
Therefore, the plastic raw materials putting into forming machine needs to be dried in advance so that it is moisture keeps below a certain amount of.
As it has been described above, by the mode that the conventional art of plastic raw materials drying process in advance is used be, bypass air through with dehydrating units such as rotating (Rotary) dehumidifier and dehumidify, put into synthetic resin after using heater heating and be dried.But, use the drying mode rotating dehumidifier to also need to other dehydrating unit, and possess the structure making the air of heating circulate, cause the defects such as apparatus structure is complicated, operation required electric power is bigger.
Plastic raw materials drying process unlike this is vacuum dried mode exactly.Be in vacuum cavity (Vacuum Chamber), put into synthetic resin raw material after dehumidifying structure.But, described vacuum drying mode is to operate with batch process form, therefore operating efficiency is far below the mode of raw material without interruption, and work production is the lowest.
A kind of mode that Fig. 1 is exactly the problem for being conventionally present described in solution and proposes.Utilize the moisture containing ratio nitrogen less than air, and possess, at the rear side of compressor 200 sucking air, the nitrogen gas generator 210 separated by nitrogen with air, its rear side possess heater 220 and to the loading hopper 230 supplying high temperature high pressure nitrogen equipped with plastic raw materials.
Then reclaiming a part of nitrogen from loading hopper to recirculate, and give loading hopper HTHP without interruption nitrogen, therefore need not dehumidifier can also make plastic raw materials be dried in loading hopper.
It is to utilize other transfer device 240 to be transplanted on forming machine 250 by the described plastic raw materials crossing range drying.
But, described conventional art needs the high price nitrogen gas generator 210 of a kind of separation of nitrogen and makes the mechanical device of nitrogen circulation, and the initial stage Meteorological needed for causing building device increases and impracticable.
