Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a method for dehydrating kitchen waste with a high water content such as cooking scraps and food residues generated in the kitchens of food factories, delicatessen factories, cafeterias, etc. and incinerating it. The present invention relates to a kitchen waste processing device for efficient and easy disposal.

[Prior art]

In recent years, as consumer lifestyles have become more popular, the amount of waste generated has also increased.In particular, kitchen waste containing a large amount of water, such as cooking waste and food waste, which is generated in large quantities at delicatessen factories and cafeterias, is becoming more and more popular. The waste is first separated from non-combustible garbage, collected in water-impermeable bags such as polyethylene, or plastic buckets, and then incinerated. There were also many hygienic problems, such as leakage of juice and foul odor during collection and transportation.

Furthermore, whether it is collected or incinerated, there are many problems in terms of processing efficiency when disposing of items that have a high moisture content or bulk, such as vegetable scraps and fish bones, in their original state. .

Therefore, it has been proposed that kitchen waste containing a large amount of water, such as cooking scraps and food scraps, be subjected to some kind of pretreatment and then collected and disposed of.

On the other hand, as a way to deal with this problem, a method of crushing the kitchen waste and discharging it into the sewage system along with a large amount of water has been considered, but in this case, the disadvantage is that depending on the amount of kitchen waste, the sewer pipes may become clogged, which increases the burden on sewage treatment. There was an inconvenience that it became large.

[Purpose of the invention]

The present invention was made in order to solve the above-mentioned problems in conventional kitchen waste processing, and it crushes kitchen waste containing a large amount of water into an appropriate size and immediately dehydrates it to facilitate subsequent handling. It is intended to.

[Structure of the invention]

In order to achieve the above object, the kitchen waste processing device of the present invention has the following features:
A rotary or other type of crusher is installed at the bottom of the hopper that receives kitchen waste such as cooking scraps or food scraps generated on the cooking table, etc., and a continuous process that receives and dehydrates the kitchen waste that has been crushed into an appropriate size by this crusher. It is constructed by connecting a dehydrator to the lower part of the crusher, and the compressed and dehydrated material is extracted by the rotation of the screw of this continuous dehydrator to the outside, thereby increasing the bulk density and making it easier to handle. This aims to eliminate leakage of juice during transportation and reduce fuel costs during incineration.

〔Example〕

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a longitudinal cross-sectional view of a kitchen waste processing apparatus in an embodiment of the present invention;
FIG. 2 is a perspective view of a cross section of the main part of FIG. 1.

First, as shown in Fig. 2, there is a rotating disk 2 horizontally at the bottom of the hopper 1, which is rotated by a motor 21 via a drive shaft 3. Together with the fixed blade 6, the pulverizer forms a pulverizer that pulverizes the kitchen waste received in the hopper 1 into an appropriate size.

As shown in FIG. 1, this flopper 1 has a water supply pipe 9, which is used for assisting in crushing kitchen waste and for cleaning after use.

Next, the kitchen waste pulverized by the pulverizer is introduced through the duct 7 through the input port 8 into a screw press type continuous dehydrator connected to the pulverizer.

This screw press type continuous dehydrator consists of a screw cylinder 11 with many drainage holes and a tapered screw 12.
It consists of a screw blade 13 provided on the outer periphery of the screw blade, both ends of which are supported by bearings 14 and 15, and a sprocket 16
It is driven by a separate motor (not shown).

A water tray 17 is provided at the bottom of the screw cylinder 11, which receives water droplets squeezed out by the screw 12, and takes them out through a drainage hole 18 for separate treatment.

In addition, the screw 12 has a tapered bottom.
As the space formed by the screw cylinder 11 and the screw 12 becomes smaller as it progresses toward the outlet due to rotation, the introduced crushed kitchen waste is compressed and dehydrated to lower its moisture content and then taken out from the discharge hole 24. Ru.

In addition, 19 in the figure is a presser ring, which is pressed by a spring 20, and is adjusted so that the pressure of the pressed kitchen waste is constant.

In addition, the volume ratio between the inlet side and the outlet side of this taper screw, that is, the compression ratio, needs to be changed appropriately depending on the components of the kitchen waste to be received. We have confirmed that it can be reached.

On the other hand, when crushing the received kitchen waste, the water supply pipe 9
Although it is necessary to supply water from the drain hole 18 to facilitate the flow of kitchen waste through the crusher and duct 7, the waste water from the drain hole 18 has almost no solid matter, so it can be discharged to the sewer pipe.

Moreover, the pressed kitchen waste taken out from the discharge hole 24 may be taken out by a method such as putting it into a bag made of polyethylene or the like, and then incinerated or otherwise processed.

In the above embodiment, a pulverizer with a set of hammer cutters is used, but the pulverizer is not limited to this type, and other types of pulverizers may be used.

〔Effect of the invention〕

The device of the present invention is not a so-called disposer, but rather crushes kitchen waste to an appropriate size and presses it to a moisture content of around 60%.
This is a device for dehydrating and making subsequent handling easier.
Its application area is not for household use, but can be effectively used for food factories and delicatessen factories that generate a larger amount of food waste, and is also suitable for places such as cafeterias where a large amount of food waste is generated.For example, the average moisture It is possible to compress and dehydrate 90% of the product to 60%, and the water it initially held is reduced to 1/6
If the water can be dehydrated to a certain extent, the juice will not leak during subsequent transportation, making it easier to handle and saving fuel when burning.

Furthermore, since the crusher and the continuous dehydrator are integrally connected, the apparatus of the present invention has the advantage of being compact and requiring less installation space.
