Types of Worm Bins
Continuous flow bins are relatively deep containers with raised floors
made from widely spaced welded wires. The system is generally bedded
by laying several sheets of newspaper over the wire floor , on top
of which is spread roughly six inches of damp bedding. The newspaper
sheets, which eventually decompose, serve to prevent bedding from initially
falling through the floor until the worms have had an opportunity to
work through it. Worms are added to the system and food waste is added
gradually, layered with bedding material, just the same as in the top-feeding
method of system management. The system is continually fed until the
bin is nearly full. The worms move upward through the feedstock/bedding
layers.
When fed at the appropriate rate, they concentrate some four inches
below the surface, where microbial activity is highest. If the system
is overfed,
the worms will spread throughout the bin material, reducing the efficiency
of the system. Once the bin is nearly full of material, vermicompost
is removed by pulling the bar across the floor, which causes a thin
layer of vermicompost to fall through. Some systems suggest scraping
a small
rake across the bottom of the floor to dislodge the vermicompost.
