screw freezer
Thread Content
How is the loading and unloading of the screw freezer implemented? Can you explain it in detail? Also, where is the slide valve?
The air volume is controlled through a slide valve, which is equivalent to a shell covering the rotor and moves along the axial direction of the rotor.
Do you see the part connected to the rod below? That is the slide valve, which can move in the axial direction.
Or look at this picture, the block above the rotor is the slide valve. When the slide valve moves left and right, adjust the length covering the rotor and adjust the effective suction volume of the screw. The gas in the uncovered area will be bypassed to the suction end, which is not the effective air volume.
At this position of the slide valve, is the load almost 100?
