Mini Plastic Dryer for Filament Extruder

This is first version, I did it after having some problems with filament made from Filament Extruder of my (designed by Sr. Hugh Lyman)
My goals: It solves two major problems (in my opinion):

Extrusion speed of filament is too slow (about <20”/per minute).
Water bubbles exist in filament fiber (plastic pellets is always moist water ,slightly wet)
The second reason makes bubbles on fiber, it appears on: extruding high speed or high temperature (from 190°C to 195°C). Can not extrusion high speed while using low temperatures: about 175°C -185°C, this case I called unripe extrusion, Plastic fibers are hard, slightly grainy if we look carefully. (Plastic tested: ABS, TPU)

Results after drying:

Extrusion speed has increased, in my extruder machine is > 60”/per minute (maximum in my extruder, I think that there may be higher)
Filament fiber: slick, smooth and especially no bubbles.

An important, all thing above is only my personal opinion, I hope and I will listen to the opinions of people, thanks.
