Description

Sterilizing device for food waste dehydration sludge and food processing apparatus containing the same {A sterilizing device for food waste dehydration sludge and Food processing apparatus containing the same}

The present invention relates to a food waste processing device that processes food waste so that it can be used as feed, biogas, and compost.

In detail, it relates to a sterilization device for food dehydration sludge that sterilizes food dehydration sludge obtained by dehydrating food waste using a food dehydration device so that it can be safely used as insect and animal feed, and a food waste treatment device including the same.

With the development of industry, economic requirements become more abundant, and living environments improve, a large amount of waste is being discharged.

Among these wastes, there are recyclable wastes such as paper and metal, and food wastes, and these wastes are usually collected separately and then recycled, landfilled, or incinerated.

Recently, various technologies for food processing devices have been provided to recycle food waste into feed for insects, animals, etc. or compost.

For example, the technology in the patent document:

Do not bury or incinerate food waste, such as the method and plant for converting food waste into feed and compost under Publication Patent No. 1996-0004300, the method of converting food waste into feed under Registration Patent No. 0271906, or the feed maker using waste food under Publication Patent No. 1999-0030453. Instead, technology is provided to recycle it into animal and insect feed or plant compost.

In addition, technology for a food waste dehydration device has been provided to solve the problem of large amounts of moisture that arise when landfilling, incinerating, or recycling food waste.

For example, the technology in the patent document:

Food waste dehydrator under registered patent No. 0649518, food waste dehydrator under registered patent No. 0736699, food waste dehydrator under registered patent No. 1128192, and food waste with a dehydrating cylinder net buffer that protects the dehydrating cylinder net under registered patent No. 2198485. A variety of technologies are available, such as dehydrators.

When recycling food waste into insect or animal feed or compost using a conventional food waste disposal device, it is converted into feed or compost without sterilization, causing insects or animals that eat the food to get sick or become sick. In severe cases, death may occur and various problems may occur, such as plants becoming diseased due to compost.

In addition, when food waste is sterilized to prevent these problems, an economic burden arises due to the cost incurred during sterilization, resulting in problems such as decreased productivity.
