Description

Food waste fermentation storage device

The present invention solves the storage problems such as odor diffusion and aesthetic damage until transported to the outside in the processing of food waste generated in a residential area, a restaurant, a market, a food processing plant, etc. To solve the problem,

By increasing the convenience of handling food waste, it is possible to separate and collect only high-quality food waste that is not mixed with foreign substances more efficiently, which promotes recycling, ie, feed and composting, resulting in saturation, bad smell, leachate problems, and incineration efficiency at incineration sites. It can solve the problems, and can be stored and taken out without spreading odor, so that the surrounding environment is not contaminated and the collection time is not limited, which not only increases the operation efficiency of the vacuum suction vehicle for collection but also reduces the manpower for handling. It relates to a food waste fermentation storage device that can reduce the amount to be taken out and increase feed rate and composting rate by fermenting food waste until launch.

In the treatment of conventional food waste, in general, by treating with general household waste, odor spreads around, and insects such as flies and cockroaches are generated, which pollutes the surrounding environment and damages aesthetics. Incinerators have also contributed to extremely low incineration efficiency. Due to these problems, the government even enacted separate collection of food waste as a way to recycle food waste. In addition, some restaurants may install food waste freezers in order to prevent the spread of odors caused by food waste and freeze them until they are taken out. Inefficient operation and processing manpower was required separately. In addition, there is a case in which a separate food waste fermenter is disposed, but there is a problem in that odor occurs during fermentation and a problem of separately treating residues left after fermentation.

The present invention has been invented to solve the social, environmental, and technical problems as described above and to maximize the recycling of food waste, and to conveniently place food waste at any place where the food waste occurs, the device is convenient to use. It is an object of the present invention to provide a food waste fermentation and storage device that is not spread odor, do not cause pests, and is stored while being fermented and then sucked out by a vacuum suction vehicle to be taken out to the outside.

A deodorizer 15 and an exhaust fan 16 connected to an exhaust pipe passage 13 equipped with a reverse flow prevention valve 14 are installed at an upper portion thereof, and a knife gate valve 25 and a rotary blade 22 at the lower portion thereof have the same rotating shaft. A pump 21 mounted on the 23, a heater 30 mounted on the pump inlet pipe 26, a knife gate valve 24, a pipe line 26 equipped with a discharge port 33, and also a fermentation container at the top. A storage tank 2 equipped with a 27 and a metering pump 28 and equipped with a temperature sensor switch 29 and a pressure sensor switch 31 therein;

It is characterized in that the discharge operation switch 41, the various operation indicator lamps 42, and the electrical components constitute a circuit so that the built-in control box 4 is interconnected.

Hereinafter, the operation state of the apparatus will be described, that is, the initial state, that is, the lid 11 is closed, that is, the micro switch 12 CLOSE, the exhaust fan 17 is stopped, the valves 24 and 25 are closed, the pump 21 is stopped, and the metering pump (2) Stopping, heater 30 OFF, temperature sensor switch 29 and pressure sensor switch 31 are preset to appropriate values, fermentation vessel 27 is filled with fermenter, and outlet 33 is The discharge hose 51 is not connected and is closed by the lid.

When the lid 11 is opened to inject food waste in the initial state, the micro switch 12 is 'open'. At this time, the exhaust fan 16 connected to the contact B of the micro switch 12 is operated so that the air flow at the inlet is directed into the inlet apparatus 1 so that odors do not diffuse out of the inlet apparatus. That is, the air sucked from the inlet by the exhaust fan 16 is filtered through the deodorizer 15 through the exhaust pipe passage 13 and then discharged to the outside. The end of the exhaust pipe may be connected to a separate exhaust pipe or to an air purifying device.

When food waste is put in and the lid 11 is closed, the micro switch 12 is 'CLOSE' so that the exhaust fan 16 is stopped, the timer T1 is started, the valve 24 is opened, and the pump 21 is operated. do. That is, the injected food waste is finely pulverized by the rotary blade 22 installed at the end of the rotary shaft 23 of the pump 21 and transferred to the pump through the pipeline, and the storage tank 2 through the pipeline 26 by the pump 21. ) It is transferred and stored inside the upper part. When the set time of the timer T1 ends, the valve 24 is closed and the pump 21 stops.

The food waste stored in the storage tank 2 is circulated and homogenized by a timer (T2) that can set the 'ON' and 'OFF' times several times a day, and the foot efficiency is improved, and food waste is fixed in the storage tank. Prevent problems. That is, when the timer T2 is 'ON', the valves 24 and 25 are opened and the pump 21 is operated so that the food waste in the storage tank is continuously operated by the time set in the timer T2 through the lower part and the conduit 26. Circulated. When the OFF time of the timer T2 is reached, the valves 24 and 25 are closed and the pump 21 stops.

In the circulation process, the metering pump 28 mounted on the top of the storage tank may be operated to inject a fermentation agent of a predetermined amount, and the temperature in the storage tank is automatically lower than the set temperature of the temperature sensor switch 29 when the heater 30 is in operation. ) Can increase the efficiency of food waste by increasing the temperature of food waste that is circulated.

In addition, the gas generated during fermentation is filtered through the deodorizer (15) through the exhaust pipe to the odor is discharged to the outside. At this time, the reverse flow prevention valve 14 is installed on the exhaust pipe 13 between the storage tank and the input device in order to prevent odors from flowing back to the input device 1.

When all the operations are stopped, open the lid of the outlet 33, connect the discharge hose 51 of the vacuum suction vehicle 5, start the vacuum suction vehicle 5 and press the discharge operation switch 41, the timer At the same time as T3 is operated, the valve 25 is opened and the pump 21 is operated so that the food waste in the storage tank 2 is sucked into the tank of the vacuum suction vehicle 5 through the discharge hose 51. . At the end of the preset timer T3 the valve 25 is closed and the pump 21 stops. Thereafter, the suction hose 51 may be separated from the discharge port 33 and the discharge process may be ended by locking the lid.

In addition, the outlet 33 is installed at a position where the vacuum suction vehicle 5 is convenient to enter and is installed by connecting the pipe long so that the vacuum suction vehicle 5 does not necessarily have to enter the position where the device is installed. There is no need to be restricted and users can install the unit in the most convenient location.

By connecting the pressure sensor switch 31 and the transmitter in the above process, the pressure signal can be linearly transformed into an electrical signal to display the amount of food waste in the storage tank. There is a way to stop automatically, but it will increase production costs.
