Description

Food waste treatment equipment

The present invention relates to a food waste treating apparatus, and more particularly, to a food waste treating apparatus capable of increasing the processing efficiency of food waste through a linkage process such as compression, grinding, stirring, and drying.

In modern times, the consumption of large quantities of materials due to changes in the living environment, resulting in the generation of garbage is increasing.

In particular, the food waste discharged from homes and restaurants contains a large amount of water, so when it is left for a long time, it becomes easy to decay. It damages the water quality of the environment and seriously pollutes the air during incineration.

Generally, food waste is treated by fermentation, incineration, feed and fertilizer, and landfilling. However, these methods require large-scale facilities. In addition, it causes various side effects such as odor or discomfort associated with collection, transportation or storage and serious social problems such as environmental pollution.

For example, food waste discarded in the kitchen pollutes the surrounding environment due to odors caused by corruption and breeding of various insects and bacteria, and is a factor of stress for housewives.

In addition, in the case of public housing complexes, such as apartment townhouses, garbage collected at home is collected in a separate container, and then collected by a food waste collection vehicle, where places where containers for collecting food waste are temporarily contaminated, Odor is generated from the container to pollute the environment of the public housing complex.

Food waste generated in each household is different seasonally, but a large amount of 30-50% of the total waste is discharged and disposed of by landfill, incineration or composting.

Recently, efforts to reduce food waste at homes and restaurants have been activated by the implementation of a waste-based waste system, and a food waste treatment device is used as a method to solve this problem.

In general, the food waste treatment device removes moisture from food waste through drying, deodorization, and the like, thereby reducing its volume and drastically reducing its emissions.

The food waste treatment apparatus includes a main body, a drying unit accommodating food waste, a hot air fan for circulating hot air inside the main body, an exhaust device for discharging the circulated air, and a deodorizing means for purifying and discharging the air of the exhaust device. Some food waste disposal units are equipped with stirrers to mix food waste.

However, the conventional food waste treatment devices as described above are forced to circulate only hot air to evaporate the moisture of the food waste, so that the food waste treatment efficiency is low, and the size of the facility is also uneconomical in terms of operation or handling. There is a face.

Thus, the conventional food waste treatment apparatus has a problem that it is difficult to use on a small scale, such as homes and businesses due to the high cost at the time of installation, odor problems during fermentation (corruption) process.

Therefore, there is an urgent need for the development of a food waste treatment apparatus capable of efficiently and economically treating food waste in a situation where there is an urgent need for reducing and recycling environmental pollution caused by food waste.

Accordingly, the present invention has been made in view of such a point, and an object of the present invention is to provide a new type in which a process of compressing, crushing, stirring, and drying a food waste is linked through a continuous automation process. By implementing the food waste treatment means, it is possible to improve the food waste treatment efficiency, and to operate the scale of the equipment in small scale. In particular, the food waste can be dried with low power and high efficiency by shortening the drying time of the food waste as much as possible. To provide a food waste treatment apparatus.

Food waste treatment apparatus provided in the present invention to achieve the above object has the following features.

In addition, a rod-shaped heater 34 to which power is connected is installed in the heater housing 33, and a spiral heater 36 to which power is connected is also installed in the blower pipe 35.

In addition, the heater housing 33 and the mixing room 26 communicate with each other through the perforations 32 having a diameter of about 10 mm formed in the room wall, so that the hot air provided by the heater housing 33 is mixed with the mixing room ( 26) can be sent inside.

In the heating unit 29, the spiral heater 36 is attached to the blower tube 35 so that hot air, not cold air, is introduced into the mixing room 26, and the rod heater 34 is also provided in the heater housing 33. ), It is a system that puts into the mixing room 26 without any heat loss, there is an advantage that can exhibit high thermal efficiency compared to other products.

In addition, the hot air inlet is made of a perforation 32 of about 10mm, the strength of the hot air injected into the mixing room is strong, there is an advantage that there is no clogging phenomenon.

Finally, the storage 38 is provided as a means for recovering the food waste that has been stirred and dried.

The storage 38 is positioned below the mixing unit 28 inside the apparatus main body 11, and a storage gate 37 is provided on the upper portion thereof, so that the storage gate 37 is opened when the drying process is completed. Together, the food waste, which has been stirred and dried, can be recovered into the storage 38.

At this time, the storage 38 may be formed of a drawer type structure, and thus, when a predetermined amount of food waste is collected, the storage 38 may be taken out of the apparatus main body 11 and collected.

In the case of the storage gate 37, the storage gate 37 may be installed in a hinged manner on a duct member extending downward from the mixing room 26, and the opening and closing operation may be performed by an actuator (not shown) such as a motor. It can be made by a conventional manner using.

Therefore, looking at the operating state of the food waste treatment apparatus is configured as follows.

5a to 5g are cross-sectional views showing the use state of the food waste treatment apparatus according to an embodiment of the present invention.

5A to 5G, first, the insert door 39 and the press door 12 on the upper portion of the apparatus main body 11 are opened to feed food waste.

When the amount of food waste injected reaches the display line "A", the press door 12 is closed by a sensing signal of a sensor (not shown), and from this time, the press board 17 is driven by the operation of the press cylinder 16. do.

Subsequently, while pushing up the press board 17 to the press door 12, the food waste is compressed to remove moisture, and the water generated from the food waste compressed in the press room 15 is press housing 14. ) And then exit through the drain 13.

When the compression process is finished, the press door 12 is opened again, and when the press board 17 is further raised to raise the compressed food waste in the press room 15 to the area of the conveying part 21, the conveying part 21 is conveyed. By the operation of the motor 19, the transfer 20 pushes the compressed food waste to the upper part of the crushing unit 25.

The food waste transferred to the upper part of the crushing unit 25 is dropped into the inside of the grind room 22, and the grinder 24 is operated by the grind motor 23 to grind the food waste.

The crushed food waste is dropped into the mixing room 26 of the mixing unit 28 as the mixing room gate 41 is opened, and the mixing blade 27 is driven to stir in the mixing room 26. In this case, the mixing pin 31 prevents food from sticking to the mixing blade 27.

While stirring is being performed in the mixing room 28, hot air supplied from the blower tube 35 and the heater housing 33 of the heating unit 29 is supplied into the mixing room 28 and dried by a hot air drying method. Will be made.

After all processes are completed, the storage gate 37 is opened, and the dried food waste falls to the storage 38.
