The present invention relates to a food waste crushing and drying apparatus, and in particular, when the food waste generated in a general home or a restaurant is introduced through a hopper, the large and hard food waste may be broken up during transportation by a crusher having a large blade. The drying is performed while rotating by the following stirrer. In the heating chamber located outside the stirrer, the drying is performed by heat by heat medium oil filled inside and heated to a high temperature, and includes the odor generated in the drying process. The present invention relates to a food waste crushing and drying apparatus for decomposing and removing odor components with cold water supplied at high pressure to air.

Generally, organic wastes such as food waste contain animal / vegetable fiber, protein, carbohydrates and calcium in large amounts, so when they are landfilled without being decomposed and extinguished, landfill extracts from organic wastes enter the ground and contaminate groundwater. Let's go.

It was designed to dissipate and destroy the conventional food waste by using microorganisms, which is disclosed in Korean Utility Model Publication No. 20-1994-12627, Korean Utility Model Publication No. 20-1994-12628, and Utility Model Utility Method or apparatus for fertilizing or feeding food waste or organic matter, such as Publication No. 20-1996-4300, Notification Utility Model Notification No. 20-1995-7395, Notification Utility Model Publication No. 20-1995-24804, etc. Known.

However, these methods and devices can have some effects in reducing organic waste, but it takes a lot of time to decompose, which leads to inefficiency. there is a problem.

In addition, stirring the "organic waste decomposing device" of Utility Model Registration No. 20-270982 and "Food waste extinction device" of Patent Publication No. 10-2006-19663 and "Food waste extinguishing device" of Patent Registration No. 10-535699 Rough structure "is known.

Utility Model Registration No. 20-270982, "Organic Waste Disposal Device," is equipped with a geared motor, a starting sprocket, an interlocking sprocket, and a chain by mounting a rotating shaft on which a plurality of arm blades are installed on the inner center horizontal line of the shell case installed inside the housing. It can be rotated by the rotary device using the inside of the shell case, by installing a steam pipe provided with a plurality of injection nozzles on the inside of the shell case to enable the injection of steam generated from the condenser into the shell case, shell case In order to control the internal temperature of the shell case by selectively supplying air generated from the chili equipped with a pre-heater.

Publication No. 10-2006-19663 "Food waste extinction device", the food waste introduced through the inlet formed on the upper side of the treatment tank is crushed and dropped while passing through the grinding mill, the crushed and dropped food waste is stirred It is extinguished by being agitated by the blades and discharged. The water is sprayed by the injection system installed on the upper side of the treatment tank to clean and discharge the inside.

Patent No. 10-535699, "Stirring tank structure of food waste extinction device", the inner side of the outer case is provided with a stirring blade inside, and the upper bottom is fixed to the drain hole in the bottom, the bottom of the upper floor The drainage port is fixed to the bottom bottom formed at the bottom of the body integrally, food waste that is introduced into the inside of the upper floor through the inlet of the outer case is stirred by the stirring blade, the discharged water discharged from the food waste is lower floor through the net After discharged to the outside through the drain will be discharged.

However, since the food waste extinction devices are operated by manual switch devices based on analog methods, they are not only inconvenient to operate, but also cannot be selectively operated by an automatic or manual mode. Since the hot water cannot be injected and supplied, there is a problem in that the waste disposal capacity of food waste falls, as well as the inside of the shell case (stirring barrel) cannot be cleanly treated, causing a bad smell.

In addition, since there is no device for cleaning the bottom of the bottom of the discharged water is collected, there is a problem that the bad odor occurs excessively, the shell case (stirring barrel) is not installed in the shell case (stirring barrel) There is a problem that the food waste dissipation device can not be smoothly operated because it is not easy to discharge the excess withdrawal water to the upper side of the).

In particular, the conventional food waste agitation (disassembly) processing apparatus has a problem that it can not be operated at a long distance by a personal computer using a network, and since the agitating tube installed inside the apparatus housing is integrally formed by welding, repair is performed. There is a problem that can not be easily performed, there is a problem that can not be beautifully maintained since the opening and closing door installed on the upper side of the device housing protrudes to the outside (upper side).

In addition, since there is no injecting device for odor removing material and decomposition material inside the food inlet, there is a problem that the smell of food waste is released to the outside when the door is opened, and the stirring blade installed on the rotating shaft is integrated. Because it is formed in the form of a problem that can not be easily assembled and repaired, and the upper surface of the support bar for supporting each stirring blade is not provided with a split blade, so when the stirring blade rotates, it is subjected to a lot of resistance by food waste. In addition, because the starting motor can not be reversely rotated because the food waste is rotated in the state caught on the support bar and the stirring blade, there is a problem that the starting motor is damaged due to strong resistance.

In addition, since cold water is sprayed from the cold water tank installed outside the divided assembly stirring barrel to wash the stirring barrel, there is a problem in that residual food waste attached to the inner surface cannot be easily separated and removed.

Accordingly, Patent Application No. 10-2006-0030465 dated April 4, 2006 (Food waste grinding drying device) was proposed.
