Description

Food waste processing system {System of dealing food dregs}

The present invention relates to a food waste treatment system.

The present invention was devised to collect various kinds of food waste generated at home or catering establishments to be useful for composting, and in particular, to efficiently organize each process for composting food waste to separate foreign matters contained in food waste. And to effectively overcome the obstacles caused by the complete dehydration of water and food waste fermentation, it is possible to reduce the processing time of food waste as well as economical recycling of food waste.

In general, food waste generated at home or a restaurant is collected separately from ordinary household waste, and microorganisms are added to the collected food waste together with an appropriate amount of sawdust and fermented for a predetermined period of time. As part of the aging process, it is partially recycled and used as farm compost.

However, the known food waste treatment device is mostly small in size, which limits the treatment of food waste, and the food waste collected with the pretreatment process excluded is stored in one place with a mixture such as sawdust, and is completely dependent on the microorganisms supplied with it. By maturation, the associated costs of food waste recycling are increased.

In addition, it is not easy to take only pure food waste by separating food waste collected in a state that is contained in a standardized bag.

In addition, it is not only limited to sorting the wastes contained in the food waste, but also in the dehydration of the food waste containing a large amount of water, it is simply discharged to the outside of the processing apparatus. Fermentation disorders are caused by the salts they have, which leads to a delay in the ripening period. Food waste is aged together with impurities, so the quality of the recycled compost is not good and it is inevitable to use in a very limited range. It is true.

By the operation of the opening and closing plate 11, the necessary amount for regeneration to compost is easily taken out and used.

Of course, since the food waste is collected in a state in which food waste is accommodated inside a normal food waste bag, it is preferable to install a leachate discharge pipe at the bottom for discharging the leachate flowing out of some broken bags and separately collecting them. Do.

Since the food waste stored in this way contains a large amount of moisture, the bags are packaged in multiple layers. The present invention provides a means for reducing the volume of food waste and bags by refining such bags together with food waste. The shredder 20 is provided with a shredding drum 21 is provided so that the volume of the bag containing the food waste is significantly reduced in the process of passing between the shredding drum 21 and any one side of the bag is opened by the internal pressure of the bag It is supplied to the inner side of the bag opener 30 in the next state.

The bag opener 30 has one end of the feed screw 31 rolled up to the outer motor M so as to transport the food waste supplied from the crusher 20 to the inside thereof and is supplied by driving of the motor M.
