Abstract

The present invention relates to a method for manufacturing coffee grounds having uniform components, and in particular, to a method for manufacturing coffee grounds in which various types of coffee grounds (coffee waste) with different components are made into uniform components. This is a drying process that dries the moisture contained in the coffee grounds collected from each store using hot air drying, after the coffee is brewed and discarded at each store: A grinding process in which the dried coffee grounds, from which moisture has been removed during the above drying process, are ground into fine particles using a mesh net; The invention is characterized by completing the ECO coffee grounds through a mixing process in which fine powder particles, ground during the above-mentioned grinding process, are fed into a mixer in equal proportions for each store and mixed.

Description

Coffee bean pulp manufacturing method for having the uniform component The present invention relates to a method for manufacturing coffee grounds having uniform components, and in particular, to a method for manufacturing coffee grounds in which the different chemical reactions of coffee beans during the roasting process are made into uniform components. Coffee bean imports are increasing rapidly every year, and the importing countries are also changing. Since most of the imported coffee beans (about 98%) are coffee grounds, the majority of the imported beans are processed as coffee grounds, with only a portion being recycled and the rest being disposed of as household waste. According to recent data, the amount of coffee grounds generated in Korea is confirmed to be 149,088 tons per year, and as the import volume of coffee beans continues to increase, it is expected that the amount of discarded coffee grounds will increase even further. Coffee grounds are classified as household waste and disposed of by incineration followed by landfilling; however, since the Ministry of Environment amended the Enforcement Rules of the Waste Management Act to allow for the recycling of coffee grounds, research and efforts to recycle them for various purposes are underway across all sectors. With the cessation of combustible waste landfilling scheduled for 2030, resource recovery is absolutely necessary. Current domestic uses of coffee grounds include air fresheners, deodorizers, eco-friendly fertilizers, bricks, flower pots, plastic additives, finishing agents, and fuel; however, the amount recycled is very small, and the reality is that most are disposed of through incineration followed by landfilling. Regarding examples of coffee grounds recycling, Korean Patent Registration No. 10-1740347 presents a method of hydrolyzing coffee grounds, mixing them with a fluid binder, and using them as a shoe sole component. Another method presented in Korean Patent Registration No. 10-2117196 involves extracting coffee oil remaining in coffee grounds using an oil press, grinding and drying the oil, and then mixing it with a fluid binder to manufacture a shoe sole component. Despite such extensive research and implementation, product utilization remains sluggish, and the consumption of coffee grounds used for recycling is very low. Korean Patent Registration No. 10-1740347, introduced above, states that in order to remove various fatty acids, residues, and oils remaining in coffee grounds, the coffee grounds undergo a hydrolysis process using an aqueous solution of sulfuric acid and sodium hydroxide, are dried and ground, mixed with a fluid binder (adhesive), and injected into a shoe sole mold to be used as a shoe sole after the binder hardens. In addition, Patent Registration No. 10-2117196 presents a method of providing a shoe sole by using an oil press to extract the coffee oil remaining in the coffee grounds, drying it, grinding it, mixing it with a fluid binder (adhesive), and then introducing it into a shoe mold to cure the binder, instead of the hydrolysis process using sulfuric acid and sodium hydroxide aqueous solution to remove fatty acids, various residues, and oils remaining in the coffee grounds as presented in the prior art patent. This is because the coffee oil remaining in the coffee grounds interferes with mixing and binding with the fluid binder. The prior art provided in this way utilizes physical bonding by mixing coffee grounds with a fluid binder and utilizing the adhesive effect of the fluid binder. Shoe soles manufactured through such physical bonding fail to provide sufficient physical properties required for shoe soles, such as tensile strength, elongation, wear index, and lightness, and do not meet consumer needs; consequently, their effectiveness in use is very poor compared to the technological development. Another Korean patent registration, No. 10-2510150, provides patent technology for an eco-friendly shoe insole utilizing coffee grounds waste and a method for manufacturing the same. According to the presented technology, it is an application of the commonly referred to liquid urethane foaming method, in which a liquid polyol resin, a liquid curing agent, a catalyst, and solid coffee powder are sufficiently mixed, and the mixed solution is poured into a foam block to induce natural foaming, thereby providing a shoe insole using a plate-shaped foam. Insoles manufactured in this way have the softness and elasticity of urethane, but hydrolysis, which is a disadvantage of urethane, occurs, and when urethane is incinerated, a carcinogenic substance called dioxin is produced, so its use is banned in Europe and other regions and is treated as a pollutant, and its usage is also rapidly decreasing in Korea. In addition, coffee oil remains in the coffee grounds, requiring careful attention during polymer stirring. All three of the conventional technologies introduced use a liquid fluid binder and urethane foaming
