Abstract

PURPOSE:To surely prevent the emission of the smells in a treating chamber to the outside by successively providing a charging chamber having a crude refuse charging port which can be opened and closed by an opening/closing cap to the upper part of the treating chamber via an aperture and constituting this aperture in such a manner that the aperture can be opened and closed by a shielding body. CONSTITUTION:The opening/closing cap 45 is opened while the aperture 3 is held closed by the shielding body 23 and the crude refuse 60 is charged into the charging chamber 5. The cap 45 is then closed and the shielding body 23 is operated to be drawn out or turned to open the aperture 3. The crude refuse 60 on the shielding body 23 is then dropped from the aperture 3 into the treating chamber 2. The aperture 3 is thereafter held closed by the shielding body 23 by reverse actuating the body 23 so as to be ready for the next charging of the crude refuse. As a result, the possibility that the smells in the treating chamber 2 are emitted from the treating chamber 2 is eliminated. The crude refuse housed into the treating chamber 2 is subjected to a fermentation decomposition treatment under agitation.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for processing food waste that makes it possible to carry out fermentation and decomposition treatment of food waste while ensuring hygiene and cleanliness at the time of inputting the food waste, and a method for processing food waste. It relates to a processing device.

(Prior Art and Problems to be Solved by the Invention) Processing food waste from homes, offices, and factories not only requires a large amount of money to collect and incinerate, but also the food waste that is thrown out can be used for birds, dogs, etc. There is also the problem of the living environment being damaged by cats, and how to deal with the ever-increasing amount of food waste has become a major social issue.

In order to deal with this situation, several types of garbage processing equipment have been proposed in recent years that use microorganisms to ferment garbage, but none of them are suitable for processing bags! It was also a large one for commercial use. Since the garbage fermentation processing apparatus itself has very excellent performance, it is desired to expand its use not only to business use but also to home use and office use.

However, conventional processing equipment cannot be used as is for home or office use, and there are specific problems associated with installing this type of equipment in kitchens, washing areas, etc. ) problems) must be resolved. In addition, in order to popularize it for home and office use, it is necessary to simplify the structure of the VI to reduce manufacturing costs, make it easier to handle, and create a structure that reduces maintenance costs. It is also necessary to consider the following.

(B) Hygiene issues If a method is adopted in which the lid of the treatment tank is opened and garbage is directly thrown into the treatment tank, as in conventional commercial processing equipment, the first problem is that the lid cannot be opened or closed. The odor inside the treatment tank will be drawn out of the tank by the rising airflow generated by opening the tank, and secondly, when food waste is put into the treatment tank, an amount equivalent to or more than the volume of garbage will be removed. The air inside the tank (containing odor) will be exhausted outside the tank. As a result of this, the odor wafts into the kitchen etc., causing a problem of impairing the hygiene of the kitchen etc.

(b) Problems with cleanliness If a system is adopted in which food waste is directly thrown into the treatment tank by opening the lid of the treatment tank, as in conventional commercial treatment equipment, the user will have to open and close the lid. Every time you open the tank and put food waste in, the fermented products in the tank become visible.
You will feel extremely unclean.

The present invention was completed as a result of careful consideration of the various problems mentioned above.

(Means for Solving the Problems) In the food waste processing method (hereinafter referred to as the method) according to the present invention, an opening communicating between a processing chamber located at the lower side and a charging chamber located at the upper side is closed by a shielding member. In this state, feed garbage into the input chamber from the garbage input port of the input chamber, place it on the shield, close the garbage input port of the input chamber, and then remove the garbage from the shield. The garbage in the input chamber is dropped into the processing chamber by pulling out or rotating the feeder, and the garbage is fermented and decomposed while being stirred in the processing chamber.

In addition, the food waste processing device (hereinafter referred to as the device) 1 according to the present invention has a food waste input port that can be opened and closed by an opening/closing mechanism 145 in the upper side of the processing chamber 2, which ferments and decomposes input food waste while stirring it. 43 are connected via the opening 3, and the opening 3 can be opened and closed by a pull-out or rotating shield 23, which closes the opening 3. In this state, the food waste thrown into the input chamber 21 is received, and the food waste on the shield 23 is removed from the opening 3 by opening the opening 3 by pulling out or rotating the shield 23. It is characterized by being made to fall inside.

In the apparatus, the processing chamber 2 and the input chamber 21 are preferably detachable, and the shield 23 is preferably formed into a plate shape and can be pulled up diagonally upward.

In addition, it is preferable to form a gutter-like part 37 in the upper part of the processing chamber 2 at a part where the inner surface of the side wall passes through, for guiding and discharging condensed water adhering to the inner surface of the side wall or the inner surface of the shield and flowing down. It is preferable to provide a deodorizing chamber 20 that communicates with the garbage processing chamber 2 throughout.

(Function) Therefore, in the device 1 according to the present invention, raw garbage (vegetable scraps from the kitchen, fish scraps, chicken bones, tea scraps, etc.)
In order to accommodate the inside of the processing chamber 2, first, the opening 3 is closed to the shield 2.
3, the opening/closing lid 45 is opened and the garbage 60 is thrown into the charging chamber 5. Thereafter, when the opening/closing M45 is closed and the shielding body 23 is pulled out or rotated to open the opening 3, the garbage 60 on the shielding body 23 flows from the opening 3 into the processing chamber 2.
It will fall inside. Thereafter, in preparation for the next input of garbage, the shield 23 is operated in reverse to close the opening 3 with the shield 23. When the food waste 60 is accommodated in the processing chamber 2 through such a procedure, since the opening 3 is closed by the shield 23 when the opening/closing lid 45 is opened, the food waste may not enter the processing chamber 2. Since the loading chamber 5 is closed by the opening/closing lid 45 during the fall, there is no risk that the odor inside the processing chamber 2 will come out from the processing chamber 2.

The garbage stored in the processing chamber 2 is fermented and decomposed while being stirred.

(Effects of the Invention) ■ When using the method and apparatus according to the present invention, when the food waste is stored in the processing chamber where food waste is fermented and decomposed, when the food waste inlet of the input chamber is opened, the charging chamber and the processing chamber are communicated. Since the opening is closed and the garbage inlet is open when the opening is opened, the odor inside the processing chamber is reliably prevented from coming out, and the installation location of the equipment is For example, the hygiene of kitchens, office washing areas, etc. can be ensured. In addition, when storing raw garbage, the fermented product in the processing chamber is not visible and does not look unclean.

Further, according to the present invention, the structure of the device can be simplified and manufacturing costs can be reduced. By the way, to solve the problem of odor when food waste is stored in the processing room, a ventilation fan is activated at the same time as the food waste input port of the processing room is opened, and the ventilation fan is configured to prevent odors from escaping outside. Although this could be solved by configuring the device in this way, it would not only increase the cost of the device but also increase maintenance costs, making it difficult to popularize it for home and office use. This makes it difficult to achieve the essential purpose of the present invention.

Further, the main operations when carrying out the present invention are two simple operations: opening and closing the garbage inlet of the input chamber and opening and closing the communication opening between the input chamber and the processing chamber.

■ In the device of the present invention, by configuring the shield to be able to be pulled up diagonally upward, it is possible to open and close the opening using the shield naturally and effortlessly, and the amount by which the shield can be pulled up can be increased by a relatively large amount. The garbage in the input chamber can be quickly dropped even if the device is not used, and the handling of the device can be further improved.

■ In the apparatus of the present invention, by providing a gutter-like part on the inner surface of the side wall in the upper part of the processing chamber, excess water in the processing chamber can be collected and guided to be discharged, thereby increasing the efficiency of fermentation and decomposition of food waste in the processing chamber. As a result, the capacity of the heater in the processing chamber can be reduced, reducing equipment maintenance costs and improving economic efficiency.

In addition, in the case where a gutter-like part is provided in this way, if the shield can be pulled up obliquely, the condensed water adhering to the shield can also be collected, improving the efficiency of collecting condensed water by the gutter-like part. It will be a scale in anticipation.

■ In the case of the present invention, when a deodorizing chamber is provided in communication with the processing chamber, it is possible to remove the odor contained in the water vapor and gas in the processing chamber, thereby improving hygiene at the place where the device is installed. It's nice to be able to do it.
