About once a week we clean out the refrigerator and throw away all the vegetables and fruits that are going bad, we fill up about two plastic bags per week. We have a very heavy duty blender (600 watts), I fill up the blender jar about 3/4 way and fill it up to about an inch below the top with water. The blender generally mixes up everything into very fine size in about 30 seconds. Every now and then, especially for carrots and tough roots, I need to run the blender for one minute. The secret is water, the more water and the less kitchen scraps, the better the blending. One thing about using a blender is that I can now blend corn cobs and they really do worms a world of good, and now they break down quickly. If it's not on the forbidden list I blend it.
If I am feeding my red wigglers I pour everything into a strainer, then I roll the mass that's left around inside the strainer behind to drain out more water... then I squeeze the mass between my gloved hands before I carry it all to the worm factory. I try to pull out little pieces and distribute all the pieces as much as possible, then I cover the whole thing with hand shredded newspapers and leaves. The biggest problem is keeping everything loose so that the air can circulate a bit so I don't get anaerobic bacteria. When I check on the red wigglers I check to see if any clumps are stuck together, I try to break them up now and then, once a week or so, just to keep it fresh.
I never said I had a worm factory for earthworms, they're in my lawn, that's how I have such a healthy green and thick lawn. After I've blended kitchen scraps like above I don't drain the mess, I walk to the front lawn and throw it right on the lawn. I do this until all the kitchen scraps are gone. Be CAREFUL to use a lot of water, otherwise you'll get this thick gooey mass on your lawn. After I'm finally done blending all the kitchen scraps I turn on the garden hose and rinse the blended kitchen scraps into the grass. Later, our brown friends come to the surface and munch away, drag it below ground, who knows, but it works. My idea is that the earthworms surface, primarily during the evenings and the nights and drag scraps of food down below. I'm not sure if they use the same tunnels, but the books all say they dig up and down in the soil beneath my lawn, this keeps the soil aerated and fertilized. The only thing I also add to my lawn is a soil conditioner called Rich Earth, it contains humic acide (humates) which provide trace materials not found in commercial fertilizers. ...and darn, my lawn is great! I've completely stopped using commercial fertilizers, my lawn is the greenest and healthiest around.
