Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a kitchen waste processing machine that dries and processes kitchen waste.

<Prior art and problems to be solved by the invention> In Europe and America, disposers are often used as household kitchen waste disposal machines. The reality is that the use of seeds is prohibited. In Japan, various kitchen waste processing machines have been proposed as alternatives to this. A typical example of this is a type of disposer system equipped with a solid content recovery device, but the drainage is extremely dirty, clogging the drain pipes, and cleaning the filters of the equipment is time-consuming. In addition, since the recovered solid content contains a large amount of water, it rots quickly and generates a bad odor, so it has not yet been put to practical use.

The present invention has been made to solve the above-mentioned problems, and by adopting a drying method in which kitchen waste is inserted into a sealed container and heated by warm air, the weight and bulk of processed kitchen waste can be reduced. Moreover, it does not generate any odor and is easy to handle.
It is an object of the present invention to provide a kitchen waste processing machine that improves the reliability of the device by interposing a filter in the kitchen waste input port and that can be easily maintained.

<Means for Solving the Problems> For this reason, the present invention includes a cylindrical drying chamber,
a partition plate disposed within the drying chamber to divide the interior space of the drying chamber into approximately two halves in the axial direction of the chamber, and freely rotatable about the rotation axis in the axial direction;
a rotational drive device for the partition plate, a cylindrical kitchen waste inlet communicating with the drying chamber, an inlet opened in a peripheral wall of the kitchen waste inlet, and an inlet located upstream of the inlet of the kitchen waste inlet. a filter fixed to the opening/closing lid of the kitchen waste inlet, and a discharge side of a blower whose suction side is communicated with the inlet through an inlet pipe is connected to the drying chamber, A heating device for heating the air is provided, and a drain pipe is connected to the introduction pipe.

<Function> Remove the opening/closing lid and put the kitchen waste into the drying chamber. The thrown kitchen waste is placed on a partition plate whose rotation is stopped. After installing the opening/closing lid, start operating the blower and heating device. Air through the filter is introduced by a blower and heated by a heating device. This air is discharged into the drying chamber and blown into the kitchen waste to heat the kitchen waste and remove moisture from the kitchen waste. The internal pressure in the drying room increases due to the temperature expansion of the water vapor and air in the kitchen waste, and due to the pressure difference with the open end of the drain pipe, the increased pressure water vapor and air flow into the drain pipe and are naturally cooled. The water vapor is liquefied and discharged. When the temperature inside the drying chamber reaches a predetermined temperature due to progress of evaporation (drying) due to continuous circulating heating, almost no air is left, and only water is discharged from the drain pipe.

Further, dust scattered during drying is removed by a filter, thereby preventing clogging of the air passage. During the drying operation, the blower and heating device are stopped as appropriate, and the partition plate is rotated by the rotary drive device, and the kitchen waste is repeatedly turned over and evenly stirred, allowing the drying operation to be restarted. Therefore, the kitchen waste is dried uniformly and efficiently down to a low moisture content.

According to this kitchen waste processing machine, the kitchen waste is dried by circulating heating, so there is very little dirt in the waste water, and the thermal efficiency is excellent. It is repeatedly stirred and dried evenly to a low moisture content, reducing the weight and volume of kitchen waste to a fraction of what it used to be, making it easier to process. Furthermore, the filter prevents clogging of the air passage, and since the filter is integrally attached to the opening/closing lid, maintenance is easy.

One end of the bypass air passage 14 communicates with the discharge hole 11a, and the other end is connected to a sewer pipe (not shown) or the like. A drain pipe, 15 is an opening/closing lid of the outlet 2a, 16 is a gasket of this opening/closing lid 15, 17 is a take-out pipe that surrounds the opening/closing lid 15 and is fixed to the drying chamber 2, and 18 is connected to the opening/closing lid 15 and is connected to the outlet 2a. operating lever for opening and closing, 19
is the fulcrum shaft of this operating lever 18, and 20 is the extraction pipe 1.
This is a storage box installed under 7.

Next, the operation of this device will be explained.

The kitchen waste is put into the drying chamber 2 by removing the opening/closing lid 7. As shown in FIG. 2, the input kitchen waste is stacked on the partition plate 4, which is in a non-rotating state. After the opening/closing lid 7 is attached to the drying chamber 2, the operation of the blower fan 10 and the heater 12 is started. Air that has passed through the filter 8 is taken into the introduction pipe 11 by the blower fan 10, passes through the casing 9, and is heated by the heater 12. The air is then discharged into the drying chamber 2 from the outlet 2b and blown into the kitchen waste through the small holes 4a of the partition plate 4, applying heat to the kitchen waste and removing moisture from the kitchen waste. The internal pressure inside the drying room 2 rises due to the temperature expansion of the air after evaporation of the water in the kitchen waste, and due to the pressure difference with the open end of the drain pipe 14, the increased pressure water vapor and air flow into the drain pipe 14, and naturally The cooling liquefies the water vapor and discharges it into the sewer. When the temperature inside the drying chamber 2 reaches a predetermined temperature as evaporation (drying) progresses due to continuous circulating heating, almost no air is present, and only water is discharged from the drain pipe 14.

Also, filter 8 removes dust that is scattered during drying.
to prevent clogging of the air passages. During the drying operation, as shown in FIG. 3, the blower fan 10 and heater 12 are stopped and the motor 5 is driven to rotate the partition plate 4, so that the kitchen waste is repeatedly reversed and evenly stirred. By restarting the drying operation in the state shown in FIG. 2, the kitchen waste is efficiently dried uniformly and down to a low moisture content. When the drying process is completed, the operating lever 18 is pulled up as shown in FIG. 4, the discharge port 2a is opened, and the motor 5 is driven, so that the kitchen waste is pushed out from the discharge port 2a by the partition plate 4, and the food waste is pushed out from the discharge port 2a by the partition plate 4. After that, it is discharged to the storage box 20.

According to this wastewater kitchen waste processing machine, the structure is such that the kitchen waste is dried by circulating heating, so the wastewater is extremely less contaminated and has excellent thermal efficiency.
The kitchen waste is repeatedly turned over and stirred by a partition plate 4 driven by a motor 5, and can be dried uniformly to a low moisture content, and the weight and bulk of the kitchen waste is reduced to a fraction, making processing easier. Furthermore, the filter 8 prevents clogging of the air passage, and since the filter 8 is integrally attached to the opening/closing lid 7, maintenance etc. are easy. In addition, the discharge port 2a is opened using the operating lever 18 provided at the bottom of the drying chamber 2, and kitchen waste can be automatically discharged into the storage box 20 by rotating the partition plate 4, thereby saving the user's time and effort. The advantage is that it is not necessary.

<Effects of the Invention> As described above, according to the present invention, the weight and bulk of processed kitchen waste can be reduced, no odor is generated, the handling is excellent, and a filter is interposed in the kitchen waste input port. This has the advantage of improving the reliability of the equipment and making maintenance easier.
