A Drier of Food Treatment System}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a food waste disposal apparatus, and more particularly, to a food waste disposal apparatus for disposing food waste, which is pulverized and dried in a vertical type drying furnace, through an inner space of a drum portion constituting the drying furnace, Drying furnace.

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.

A device for treating food waste attached to a conventional sink includes a feeding port into which food waste is fed, a dehydration / cutting section for cutting and chopping the food waste by dewatering by compressing the food waste, a feeding section for moving the dehydrated and cut food waste to one side, And a drying unit for drying the food waste by removing moisture by high heat while uniformly turning over and dispersing the food waste dewatered and cut by the rotary blade rotated in one direction by the rotary blade.

In recent years, free standing food processing machines that can be freely installed in the home as well as a sink-mounted type are becoming popular. The free-standing type food processing apparatus is also processed through the steps of input, cutting, stirring, crushing, drying, and the like as in the case of a sink attaching type.

The process of agitation, grinding, and drying is mainly carried out in the drying furnace of the food processor. After the series of processes such as grinding are performed, the drying must be performed. Especially, in the case of the conventional drying furnace, And after the grinding and drying operation is performed to some extent, the user operates the door leading to the discharge port to induce the discharge.

The above-described conventional structure requires a separate additional structure at the lower side of the drum unit since the drying and pulverizing food is freely dropped from the inside of the drum unit constituting the drying path to induce the discharge. In addition, there is a limitation in terms of the fact that the pulverizing materials remaining in the drum portion can be neatly removed. In addition, since the user can process the emission only after a predetermined amount of food is processed, it is difficult to estimate the processing time in terms of the user.

In addition, since the user requires a system capable of processing the food in the real-time drying oven, the necessity of the drying oven to smoothly perform the operation even if the user does not pay extra attention in the process of operating the drying oven after the food is inserted It is getting bigger.

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.

An object of the present invention is to provide a drying furnace of a food processor in which food waste put into a vertical type drying furnace can be discharged onto the outer peripheral surface of the drying furnace through a space inside the drying furnace in real time by rotation of an agitating screw disposed therein will be.

Molybdenum is used as an anode, grid and supports of electronic tubes, contacts of electric circuits, high temperature parts of heat resistant materials, special alloys, heating wires and coatings. It is very strong mechanically from cryogenic temperature to high temperature. It is a popular trend.

The drum unit 110 includes an inner drum 114 and an inner drum 114. The inner drum 114 is disposed inside the outer drum 112 and the outer drum 112 with a predetermined interval therebetween, Respectively. At least one discharge hole 116 formed to pass through the upper and lower surfaces of the inner drum 114 is formed on the discharge portion 115. Preferably, the discharge hole 116 may be formed in a bottom edge portion of the inner drum 114.

The pulverizing material pulverized by the stirring screw 130 after entering through the upper loading port 118 of the drum unit 110 is discharged through the discharge hole 116 and the outer drum 112 formed on the lower surface of the inner drum 114, And is discharged to the outside of the drum portion 110 through a space between the drums 114.

2, a blocking plate 128 is installed between the outer drum 112 and the inner drum 114 of the upper surface portion of the drum unit 110. The blocking plate 128 is provided with a discharge port 126 Is formed and finally the food processing material to be conveyed to the discharge passage side is finally discharged. The discharge port 126 may be connected to a storage box 180 through which the processed food waste can be collected.

A spiral rib 120 is formed in a space between the outer drum 112 and the inner drum 114 in a coil or spring shape while contacting the inner surface of the outer drum 112 and the outer surface of the inner drum 114, And the discharge passage 113 is formed on the space between the outer drums 112 and 114. [ That is, when the rib 120 is formed along the space between the drums 112 and 114, a spiral passage that is formed naturally occurs. The spiral passage is directly connected to the discharge passage 113 of the pulverized material do. The discharge passage 113 may be formed to extend from the discharge hole 116 to the upper surface side of the drum 110 through the lower edge of the drum 110.

It is preferable that the drum portion 110 has a structure in which the center portion protrudes further upward than the outer circumferential portion in order to smoothly discharge the pulverizing material through the discharge hole 116 in the drum portion 110. [ Here, the discharge hole 116 is formed so as to be further away from the rotating body 132 from the upper portion to the lower portion. That is, a structure is formed in which the pulverizing material can move to the lower outer circumferential surface side of the drum portion naturally by gravity during operation of the drying furnace.

The blower 140 may be additionally disposed in the space between the outer drum 112 and the inner drum 114 so as to move the pulverizing material discharged from the discharge hole 116 to the discharge passage. And the rotary shaft 162 so as to blow air toward the outer peripheral portion of the drum portion 110. The blower 140 receives power from an external power source 170.

A cylindrical boss 102 is rigidly installed at the center of the drum 110 and the rotating shaft 162 is inserted into the boss 102 so as to be rotatable. A rotating body 132 is connected and fixed to the rotating shaft 162. The rotating shaft 162 is connected to the driving unit 160 to receive power.

The stirring screw 130 is provided with a rotating body 132 rotating along a vertical axis of rotation and at least one blade 134 extending along the radial direction from the center of the rotating body 132. The blades 134 may be formed with a predetermined gap so as not to be interfered with the surface of the inner drum 114, and may have a structure capable of forming a flow of air from the upper side to the lower side. That is, the air above the blade 134 is pressurized by the rotation of the blade 134, so that the pulverized food waste can flow toward the discharge hole 116 side.

The blade 134 operates between the inner circumferential surface of the inner drum 114 and the rotating body 132. For example, the shape from the inner circumferential surface of the inner drum 114 to the rotating body 132 is formed in a " . The cutting edge on the outer side of the blade 134 proceeds by a crossing with the grinding rib 117 having a constant thickness formed inside the inner drum 114.

The drying furnace 100 of the food waste disposal apparatus according to the present invention finely crushes the food waste put into the drum unit 110 by using the rotating screw 130. The drum 100 further includes a drying heater 150 So that drying can be performed simultaneously.

Hereinafter, the operation of the drying furnace 100 of the food treatment apparatus according to the present invention will be described. First, the food is supplied to the inside of the drum unit 110 through the inlet 118, and the operation of the drying furnace 100 is started. The rotary screw 130 is rotated by providing a rotational force along a driving line that connects to the driving unit 160, the rotating shaft 162, and the rotating body 132 so that the charged foodstuff is crushed and agitated. A pressure difference is generated in the upper and lower portions of the rotary screw 130 during the rotation so that the pulverized food inside the drum 110 is naturally introduced into the discharge hole 116 side. That is, for example, the shape of the blade can be made to be similar to the shape of a blade of an electric fan, thereby enabling air to move.

Since the discharge hole 116 is formed so as to move away from the rotating body toward the lower surface, the dropped material naturally moves to the outer peripheral surface side of the drum portion 110. The processed material moves in the upward direction of the drum portion 110 along the spiral-shaped discharge passage. In this process, the blower 140 blows air into the discharge passage side to smooth the moving food. The food waste treated along the discharge passage is discharged to the outside through the discharge port 126.
