s2: then through a spiral steam channel in the form of a spiral blade between the outer steam pipe and the outer steam pipe; due to the fact that the mass fraction of the water vapor is large, the water vapor can be gathered and adhered to the outer steam pipe due to the centrifugal effect when the water vapor passes through the spiral steam channel;
s3: then, steam enters the steam inner pipe, the flow direction of the steam is changed for many times due to the blocking of the steam baffle, and water vapor with large mass adheres to the steam baffle;
s4: and finally, outputting the dry steam subjected to steam-water separation by a steam output pipeline, and entering the next working procedure.
Preferably, the outer steam pipe and the inner steam pipe are both seamless stainless steel pipes, and the helical blade is made of one of stainless steel metal materials or stainless steel metal materials and comprises a plurality of helical blades and a long baffle; the long baffle and the blades form a spiral steam channel.

Preferably, the method further comprises the following steps: after a certain amount of condensed water is collected, a valve of the water diversion hole is opened, so that the accumulated condensed water flows out.
The design of the steam baffle plate enables the fluid to change the flow direction in the separator for many times, and because suspended water drops have larger mass and inertia, when the flow direction of the baffle plate is changed, dry steam can bypass the baffle plate and continue to move forwards, and the water drops are accumulated on the baffle plate; the design of the helical blades enables fluid to flow at high speed in the separator to generate cyclone, and suspended water drops with large mass are adhered to the wall surface of the steam outer pipe under the action of centrifugal force; these accumulated water droplets eventually fall to the bottom of the separator and are drained through a drain valve.

Tests show that after the EPS packaging machine is used, the steam penetration time of the EPS packaging machine is saved by 6s, the steam quantity is saved by 21%, the production benefit is improved by 39%, the mold stripping rate is accelerated, and the product quality is improved.
