Description

Fried crumbs-based pellet manufacturing apparatus capable of recovering waste cooking oil and method using the same}

The present invention relates to a frying crumb-based pellet manufacturing apparatus capable of recovering waste cooking oil, and more specifically, to effectively form a frying crumb having a low initial moldability and very high initial content in pelletizing, and recycling waste cooking oil. The present invention relates to a frying crumb based pellet manufacturing apparatus and method capable of recovering waste cooking oil that can increase economic value.

Tempura crumbs are common ingredients in the general restaurant cooking process, especially in chicken frying and cooking and pork cutlet cooking. These fried crumbs contain waste cooking oil in the pores, and the amount of this cooking oil is more than 70% of the fried crumbs. The waste cooking oil in the fried crumbs flows out of the fried crumbs depending on the surrounding conditions and pollutes the environment. To dilute the waste cooking oil from the fried crumbs, it takes water equivalent to 200,000 times the amount of the used cooking oil. However, most companies that produce fried crumbs are not aware of the environmental pollution caused by the fried crumbs, so they are not properly collected.

In addition, the pellet means that wood is crushed and compressed to form a cylindrical pellet, and since the heat generation per unit volume is high and the shape and size are constant, quantitative supply is possible, so fossil fuels in thermal power plants and boilers It is widely used as a substitute material for.

Recently, due to the exhaustion of fossil fuels, efforts to produce renewable fuels using recycled products have been attempted. Biodiesel is one of the most widely used biofuels along with bioethanol, and refers to non-polluting fuels made from vegetable oils such as soybean oil, rapeseed oil, waste cooking oil, and seaweed oil. In addition, for the production of biodiesel, biomass pellets, which use food residues generated in the refining process for collecting and using waste cooking oil, are receiving attention.

The fuel using the biomass described above is easily produced during transportation, storage, and combustion, and is capable of increasing the amount of heat due to combustion, so that it is produced in the form of a pellet that also has economical efficiency as an energy source. Furnaces are used for forestry logging, organic wastes from agricultural and forest by-products such as waste wood, rice hulls, and plant stems among construction wastes and domestic wastes.

 Particularly, when the collected fried crumbs containing waste cooking oil are produced as pellets as raw materials, they can be used not only for fuel but also for feed. There is a disadvantage in that it requires a lot of production cost compared to the relatively low general wood.
