Description

[0001] The present invention relates to a drier of a food treatment system having a rotary screw,

[0001] The present invention relates to a drying furnace of a food processing machine having a rotating screw, and more particularly, to a drying furnace in which a rotating member having a rotating screw and a protruding portion formed therein is interlocked with the drying furnace, To a drying furnace of a food processor.

Generally, there are food waste processing methods such as a fermentation treatment method, an incineration treatment method, a method of recycling to feed and fertilizer (compost), a method of landfilling into soil, etc. However, the above- In addition, it poses serious social problems such as environmental pollution and various side effects such as odor and inconvenience due to collection, transportation or storage.

Accordingly, there is an urgent need for a method that can reduce environmental pollution caused by food waste, and can be recycled and used.

Meanwhile, despite the fact that the total number of households has exceeded 10 million households in Korea, countermeasures and results of food waste disposal related to environmental pollution are still insufficient. The main reason for this is the lack of awareness of waste of resources and environmental pollution by housewives.

Accordingly, in order to effectively suppress the generation and recycling of food waste, it is urgently required to develop a household food waste treatment apparatus capable of solving such problems.

In general, a device for treating food waste connected to a household sink can remove moisture from food waste through a series of processes such as dehydration, cutting and drying, and reduce the volume of the food waste, thereby greatly reducing the amount of the waste.

That is, stirring is performed only by the height of the blade of the rotating screw, which is responsible for stirring / crushing, in the drying furnace, so that the introduced foodstuffs can not be finely crushed as a whole.

In addition, when a light material such as starch or the like is injected, it may not be well pulverized and may be aggregated into agglomerates, resulting in an excessive load on the rotating screw and the motor.

On the other hand, in recent years, a freestanding type food processor, which is not installed in a conventional sink, is widely used among consumers, and food waste remains in the dryer without being finely crushed among consumers The satisfaction of the consumers tends to be lowered.
