technical field

The invention belongs to the technical field of meal waste treatment, and in particular relates to a meal waste treatment device.

Background technique

With the improvement of living standards, people’s daily life and food processing and catering service industries will generate a lot of garbage, including discarded vegetable leaves and leftovers. These garbage are collectively referred to as meal waste. Meal waste contains extremely high moisture and organic matter, which is easy to rot and produce stench. Therefore, kitchen waste needs to be properly treated and transformed into new resources. Organic matter can be used as fertilizer and feed.

Since kitchen waste contains extremely high moisture, up to 80%, it is very necessary to separate dry and wet food waste. The current kitchen waste treatment device will distinguish between dry and wet separation trash cans, and manually perform dry and wet separation operations on the garbage when dumping garbage. This traditional manual dry and wet separation trash can not only makes the size of the trash can larger, but also wastes the time of manual dry and wet separation. Moreover, the water in the kitchen waste also contains some oil stains.

The existing food waste treatment device has the situation of manual dry-wet separation, which cannot achieve the effect of automatic oil, water, and matter separation. The oil, water, and matter separated from dry-wet separation cannot be fully utilized, causing environmental damage and impact. For this reason, we propose a meal waste treatment device.
