WEIGHT REDUCTION METHOD OF FOOD WASTE IN WEIGHT RATING SYSTEM

摘要

The present invention relates to a method for reducing the amount of food waste which supports pay-as-you-go basis, and is provided to discharge food waste in a powder form by measuring the amount of food waste in a pay-as-you-go basis food waste collection device and crushing the food waste. For the purpose, the present invention provides a method for processing pay-as-you-go basis food waste by including: a food waste insertion step for inserting food waste by recognizing a user card using a card recognition unit (20) and opening a cover (14); a weight measurement step for measuring the weight of the food waste; a transmission step for transmitting user information and the weight of the food waste to a management server, and further includes: a reduction processing step (ST30) for crushing the inserted food waste and stirring into a powder shape; and a condensed water processing step (ST50) for sterilizing and deodorizing condensed water which is formed by cooling vapor generated when drying the food waste, wherein the reduction processing step (ST30) comprises: a crushing step for crushing the food waste inserted through an inlet (12) in a crush unit (42); a drying step (ST310) for stirring and drying the crushed food waste in a stirring (44) and a heating unit (46), respectively, and converting into a powder shape; a cooling step (ST320) for cooling the vapor generated when drying the food waste in a heat exchange unit (50); and a discharge step (ST330) for discharging the food waste dried in a power shape through a discharge unit (60).
