In addition, the present invention can be applied to the field regardless of mass production or small-volume production by arranging several equipment in parallel in the transverse direction. possible effects can be obtained.

In addition, according to the present invention, since the supply hopper part is configured in a screw transfer method, it is possible to obtain the effect of supplying a certain amount of processed food materials without agglomeration or damage.

In addition, the present invention can obtain the effect of thoroughly maintaining hygiene management by separating the multi-stage conveyor as necessary to clean or sterilize after work.

In addition, the present invention is an excellent device developed by the on-site demand of producers in the reality that 100% of the production of sliced fruit, which has been in high demand due to government measures, etc. depends on manpower.

The scope of the present invention is not limited to the above-described embodiments and modifications, but may be implemented in various forms of embodiments within the appended claims. Without departing from the gist of the present invention claimed in the claims, it is considered to be within the scope of the claims of the present invention to various extents that can be modified by any person skilled in the art to which the invention pertains. In particular, in the present invention, sliced fruits include various fruit foods such as apples and packaged in dices, individual fruits such as cherry tomatoes, candies, chocolates, Korean sweets, and powdered raw materials such as flour. It should be understood as a broad concept. do.
