Description

food waste disposal device

The embodiment relates to a food waste disposal apparatus.

In general, food waste discharged from homes or restaurants is collected in a separate public collection box to remove moisture and landfilled, or processed separately and then used as feed or compost for livestock.

Most of the food waste is collected in a wet state. Therefore, it is true that food waste has a high moisture content and is bulky.

As such, if the waste has a lot of moisture, it may easily decompose, and if the volume is large, the weight also increases, so there is a problem in handling and handling in transport and processing.

On the other hand, since it is most desirable to minimize the amount of food waste consumed and left behind, the ordered diet system is being widely implemented as a social enlightenment as part of an effort to reduce the amount of food left behind, but its effectiveness is very insufficient. am.

Therefore, it is desirable to actively reduce food waste at the waste generation site, and a food waste treatment apparatus has been developed for this purpose.

The conventional food waste treatment apparatus not only reduces the weight by drying wet food waste by heating, but also finely pulverizes the food waste so that the volume can be reduced at the same time.

However, in most of the conventional food waste treatment apparatuses, numerous devices for implementing a plurality of processes in order to pulverize and heat food waste to remove moisture and then send the treated waste to a separate collection box are structurally complicated, so manufacturing costs are high and frequent It is becoming an obstacle to commercialization due to failure.

Also, in the related art, most food waste treatment devices installed in kitchens have a problem in that they cannot completely remove odors generated during food processing. That is, since odors generated during food waste treatment are often leaked to the outside and pollute indoor air, there is a problem that not only causes discomfort to users, but also exposes them to various polluting sources for hygiene.

In order to solve this problem, the applicant's registered Patent Publication No. 10-1306679 "food waste treatment apparatus" simplifies the structure of the food waste treatment apparatus and includes a condenser that circulates the refrigerant to the cooling coil to provide the food waste By removing moisture from the exhaust from the food waste disposal system, it is possible to significantly reduce the manufacturing cost, lower the product defect rate, and effectively remove odors generated during food processing.

However, in order to implement a cooling method using a cooling coil and a condenser that circulates the refrigerant in the food waste treatment apparatus, there is a problem in that the maintenance cost increases because the refrigerant is periodically replenished, and the cooling coil and the refrigerant are circulated. Since a condenser is required for this purpose, the cost to purchase it is high, which is a cause of increasing the manufacturing cost. During installation, there is a complicated configuration and there is a risk of refrigerant leaking when the cooling coil is damaged, making installation difficult.

On the other hand, since most of the conventional food waste treatment apparatuses are fixedly installed at a certain place in the kitchen, there is a big problem in terms of space that cannot be used in a kitchen of a narrow space where it is difficult to install the food waste treatment apparatus.

Therefore, a practical and applicable technology for a food waste treatment device capable of quickly and easily treating food waste in the case of food waste, lowering manufacturing and maintenance costs, and realizing a minimal space design with a simple configuration This is an urgent need.
