The present invention is a fertilizer by using a large amount of organic waste containing a large amount of water from the livestock waste and livestock slaughter waste generated during livestock raising and slaughter waste including livestock slaughter, or food processing related to leftover food and agricultural products Or a method for producing a raw material of a feed, a method for producing a fertilizer or a feed using the raw material prepared by the method, and a method for producing a liquid fertilizer and a microbial medium liquid from a high moisture content organic waste.

The treatment of the remaining food and livestock manure and waste from slaughter of livestock or organic waste from the distribution and processing of various food factories and agricultural products is carried out by ocean dumping, landfill or microbial fermentation. Through the drying process through evaporation of water using energy or heat, it is selectively used as a raw material for feed or fertilizer.

However, these methods incur a lot of energy costs in common, and at the same time, the occurrence of odor problems during drying or fermentation of microorganisms, secondary pollution or environmental problems is inevitable. Therefore, there was a problem of cost generation at the same time as the movement route was contaminated.

In addition, when the livestock's blood or livestock manure was resourceized as fertilizer and compost without high temperature sterilization process, harmful insects (flies, mosquitoes, etc.) occurred extensively and serious disease transmission problems related to them occurred. In particular, if manure or livestock manure is composted or fertilized without sterilization, contamination or transmission of parasites or infectious pathogens could be a problem.

In addition, in the case of the organic wastes mentioned above, a considerable amount of leachate is generated during the treatment process due to the high water content, and during drying, more than 70% of the dehydrated filtrate by the dehydration device is generated. Economic burden such as facility investment or construction was very large. In particular, when the dehydration liquid is evaporated by high temperature heat, the smell of water vapor is severely generated, and air pollution due to secondary pollution such as dust and dioxin generated by high temperature heat treatment occurs.

In addition, when the remaining food or food residues contain a lot of starch-containing ingredients (rice), the moisture is not easily separated or evaporated due to the properties of the starch during the drying process. Tangle and clinging to internal screws or conveying devices can cause dryer failures. Therefore, such starch-rich organic wastes or remnants have been inconvenient to be separated and reprocessed separately.

In the case of the dried or composted treatments at such a high cost and time, due to the large amount of water and the effects of unsterilized decayed or pathogenic microorganisms during storage, decay occurs with severe odor, resulting in storage. There were various problems on the screen. Due to these problems, composting or liquid fertilization using livestock manure, which is a feces of livestock, has not been made well.
