Description

Residue treatment device having preliminary cleaning function {Apparatus for treating leftover food having preliminary cleansing function}

The present invention relates to a residual material treatment apparatus having a preliminary washing function, and more particularly, by forming a water flow on the dish with the inserted residual material, removing the residual material from the surface of the dish, and removing salt contained in the removed residual material. It relates to a residual material treatment apparatus having a pre-washing function.

Recently, with the development of industry and the improvement of people's living standards, the amount of household waste has increased rapidly, and the cost of disposing of the waste is enormous, as well as causing various environmental problems when the waste is incinerated and landfilled.

In particular, in the case of food waste, since the waste contains a lot of moisture, incineration is difficult, it is easy to decay, and it causes many problems such as polluting the surroundings during landfill.

However, group catering centers and restaurants, such as company restaurants where a lot of leftovers are generated, suffer a lot of difficulties because there is no proper leftover processing device.

In order to solve the above problems, the residual material is conventionally inserted into a centrifugal separator-type cylinder with a hole in the cylinder and rotated at high speed to remove moisture, or hot air is blown at the same time while rotating the centrifuge at high speed. An apparatus for drying residue treatment was provided.

However, such a conventional residual material treatment device does not completely remove the moisture in the residual material, so a separate device such as reprocessing or a hot air dryer is required to remove moisture, and since only the moisture is removed, the salt in the residual material is not properly removed, resulting in waste. There were problems that caused secondary environmental pollution during treatment.

Therefore, in removing the residuals from the tableware in the related art, a method that can be recycled as feed or fertilizer through the residuals by removing salt remaining on the residuals through moisture must be devised.
