Waste Food Shredder Compost Maker Machine

Abstract

 Kitchen refused food items like vegetables, green leaves, eggshells, meat, boiled rice, all sorts of fruit peels, etc, (the list is endless) is known as kitchen waste or organic waste. A waste converter is machine used for the treatment and recycling of this wet organic material in a manner of cutting them in to a small piece using manual shredder and sterilizing the waste by heating the material at low temperature to kill the hazardous bacteria by which healthy compost will be produced which can be used as soil compost. A tool or machine which can be used for cutting above said materials in to small pieces, here manually operated mechanism is used as a separate device. After cutting the organic waste, it must be poured in to the separate container made of acrylic sheets. The idea of using clear acrylic sheets is to see through the process, for this purpose, hard sheets of 4mm thick are used. Not only kitchen waste, garden waste like green grass, flowers, leaves, etc, also can be converted in to compost. PIC 16F676 processor is used to measure the temperature through LCD. This IC is having built-in-with ADC such that additional ADC is not required for converting analog data produced by the temperature sensor in to digital. To prove the concept practically, one medium size container will be fabricated with Acrylic and metal angles structure. All sides of the container will be constructed with acrylic sheets to see through the process. With the help of a manually operated shredder, solid dry organic waste can be pulverized to make in to small pieces. Sterilization process is considered to kill the bacteria, for this purpose hot air blower is used and this device is energized and reenergized independently through relay wired with IC555 timer chip.
