Description

Using food waste for charcoal fire brown coal}

The present invention is one of the ways to efficiently recycle food waste discharged from homes, apartments, restaurants, hotels, etc., and then collected, sorted, dried and shredded, and then mixed with wood powder, ink, etc. It is about.

Food waste refers to fish guts, heads, food defects, etc. that are discarded when the food ingredients are trimmed before cooking at home or in a restaurant, and leftovers that have been left by eating food and discarded during the sale or distribution of food.

Since these food wastes contain 80 to 90% of moisture, when mixed with other wastes, the moisture permeates into other wastes and prevents the proper disposal of the whole wastes, and causes odors due to decay, etc. Due to the salt component contained in it, there is a problem of generating environmental hormones, such as dioxin, has emerged as a social problem.

In particular, in accordance with the London Convention, the government has established a 2006 comprehensive measure of land waste disposal at sea, and has phased out the allowable emissions of oceans. In other words, the construction of bans on dumping of marine sludges and sewage sludges in 2006 is prohibited, and manure and sewage sludges are banned from dumping at sea this year.

Accordingly, the present invention is to reduce the water content by 90 to 93% or more within 30 minutes through the process of processing in an environmentally friendly system for the recycling of food waste, general wood powder, juniper wood powder, palm wood powder and ink powder The mixture was carbonized to develop charcoal roasting charcoal, which is an alternative fuel of charcoal used in restaurants.

The amount of food waste generated in Korea is about 15,000 tons per day, and the amount of food waste generated per person is 0.35Kg, which is much higher than in developed countries such as Germany (0.27Kg) and the UK (0.26Kg). Most of the food waste was incinerated, landfilled or dumped at sea. However, since 2005, direct landfilling has been banned, and since 2013, the ban on marine dumping of effluents has been banned. In addition, the costs of incineration and the generation of environmentally harmful substances and odors such as dioxins generated during incineration have serious environmental problems and disadvantages in recycling useful waste resources.

Accordingly, research on composting and animal feed has been actively conducted as one of the food waste recycling methods, but it is also difficult to process each animal into a form suitable for the diet and taste of each animal. Due to the low demand of consumers, technology development for fueling food waste has been actively conducted in recent years.

As an example of fueling technology of these food wastes, Korean Patent Publication No. 10-2000-0012514, "Method of manufacturing solid fuel using food waste", and Korean Patent Publication No. 10-2005-0032057, "Food waste is charcoal raw material. Method ", Korean Patent Publication No. 10-2008-0042060 discloses" a method of manufacturing solid fuel using food waste ", etc., and Korean Patent Registration No. 10-0453878" charcoal manufacturing apparatus and method using food waste and Apparatus ", Korean Patent No. 10-0532624," Method of manufacturing solid fuel using food waste ", Domestic Patent No. 10-0557471," Method and apparatus for manufacturing charcoal using food waste ", Domestic Patent No. 10- No. 0729816, "Manufacturing Method of Solid Alternative Fuels and Garment Agents Using Food Waste", and Korean Patent Registration No. 10-0735543, "Food waste and solid synthetic resins are used to remove solid fuel.

Figure 2 is charcoal grilled lignite prepared using food waste according to the present invention.

The present invention collects food waste and sorts foreign substances such as metals and vinyls with a sorter, and then dilutes salts, removes odors, and sterilizes them for 30 minutes at a temperature of 180 to 200 ° C. such that water content is 8-10% by weight or less. The tea is dried and pretreated to get food waste solids. The pretreatment process was used in the food waste device and food recycling method of the domestic patent Nos. 10-1088014 and 10-1114315 owned by Food Energy. The dried food waste powder was mixed with ordinary wood powder, juniper wood powder, palm wood powder and ink in a rotary kiln reactor and carbonized by indirect heating. At this time, the carbonization temperature is maintained at 600 to 1000 ℃. The components and composition ratios of the carbonized mixtures are shown in Table 1.

Composition and Composition of Carbonized Mixture ingredient Composition ratio (part by weight) Food Waste Dry Grind 100 Common wood flour 80-150 Juniper wood powder 20-30 Palm tree flour 30-50 깻 10-20

In the above carbonized mixture, small amounts of organic rock edible molasses and kaolinite as inorganic binders and kaolinite as inorganic binders are mixed well with a small amount of a complexing agent commonly used in the art, and then put into a pellet extruder. By extrusion molding to produce lignite charcoal of the present invention. The charcoal roasted lignite has a combustion duration of 2 hours per kg, has a calorific value of 4,700 kcal / kg, and its composition and composition ratio are shown in Table 2.

Composition ratio of charcoal roasted lignite ingredient Composition ratio (part by weight) Carbonized horn 100 Elvan Stone Powder 3-8 Edible molasses 5 -10 china clay 5-10 Complexing agent 0.05-0.1

When the content of the above-mentioned elvan rock powder exceeds 8 parts by weight and the content of kaolin exceeds 10 parts by weight, combustion may be delayed and the calorific value may be lowered.

 If the content of elvan is less than 3 parts by weight and the content of kaolin is less than 5 parts by weight, the amount of far-infrared rays or anions is reduced and air purification is insufficient. Therefore, the content of elvan is 3 to 5 parts by weight, and the content of kaolin is 4 to 6 parts by weight. desirable.
