Environmentally friendly paper making method using coffee grounds as materials

The invention relates to an environmentally friendly paper making method using coffee slag as a material, in particular to a paper making method capable of reducing the consumption of earth resources.

Due to the progress of society, the increase of garbage and environmental pollution have accelerated the disappearance of the global village. In order to save the earth's natural resources, many advanced countries in the world have established resource recycling systems. The benefits of resource recycling are the best use of resources. Decaying is magical, reducing the destruction of nature.

Resource recovery can effectively use recycled materials, such as kitchen waste, PET bottles, glassware, plastics, metal products and paper, to reclaim the recycled items into daily necessities such as recycled paper, fertilizer, fuel, etc.

Modern people are influenced by Western culture, and the demand for coffee is getting bigger and bigger. Whether it is to cook a cup of strong coffee or a convenience store and beverage store everywhere, the freshly brewed mellow Coffee, after careful tasting, not only enjoys the sense of smell and taste buds, but also refreshes the mind and provides many people with a full day of vitality.

However, after drinking coffee, it is always inevitable to leave coffee grounds. The amount is quite amazing after a long period of time. It is prone to mildew after a long time. Therefore, some people use the concept of resource recycling to start using it. It can be applied to home maintenance, deodorization and composting. In the daily necessities, even with coffee grounds to raise cattle to produce milk.

However, the actual situation is indeed, regardless of the above method, although it can be returned Part of the coffee grounds, but still can not be compared with the speed of coffee grounds, the application of coffee residue recycling is still insufficient, the industry will still have processing problems.

In view of this, how to provide a solution to the problem of insufficient recovery of coffee grounds, so that coffee slag can be applied more quickly and in large quantities, and the coffee slag can be practically applied, so that the industry is willing to apply the environmentally-friendly paper method using coffee slag as a material. This is a subject to be improved by the present invention.

Among them, through the application of this method, a good coffee slag (1) recycling method is provided, which enables the coffee slag (1) to be quickly applied in daily life, which can not only solve the problem of insufficient application of coffee slag (1). And it can also reduce the amount of pulp (6) used. In the long run, the amount of felling in the woods can be reduced, and it can also achieve an environmental protection effect. Also, because the entire method does not produce additional waste water and waste materials. It is environmentally friendly, and the paper (8) that is finally produced can be decomposed by the environment and is very environmentally friendly.

Secondly, through the use of the water circulation device (10), the grease in the coffee grounds (1) is removed, and the filling material (5) and the pulp (6) are mixed perfectly, and the paper (8) formed after processing is not caused. The problem of separation occurs, and most importantly, water can be recycled many times, without adding water all the time, it can reduce the consumption of water resources, and can effectively achieve the effect of reducing the consumption of earth resources.

Furthermore, through the application of coffee grounds (1), the application amount of the coffee grounds (1) can be utilized to achieve different pulp (6) saving effects, and at the same time, more diverse papers (8) can be provided, providing different The paper (8) is selected, and most importantly, the overall cost of the method of the present invention is not high, which is advantageous for popularization and application, and has good industrial applicability.

In addition, the ground coffee grounds (1) can also emit a slight coffee fragrance, making the paper (8) more popular with consumers.

In the above, the predetermined particle diameter is from 0.5 to 50 μm. Among them, the coffee grounds (1) is processed to a particle size of 0.5 to 50 μm, so that the filling material (5) can be sufficiently mixed with the pulp (6) without affecting the use, so that the paper (8) can be safe and secure. It is used in everyday life.

In the above, the steps of the papermaking process include, in order, a slurrying step (a), a refining step (b), a mixing step (c), a papermaking step (d), a forming step (e), and a pressing Step (f), primary drying step (g), coating step (h), secondary drying step (i), calendering step (j), and coiling step (k) are as shown in FIG.

Among them, through the cooperation of the papermaking process, it is possible to provide quality and environmentally friendly paper (8) without increasing the excessive cost of the paper without any excessive papermaking process, so that the industry does not have to worry about the production. Paper (8) will be overpriced, causing unrealistic problems.

In the above, the proportion of the coffee grounds (1) [solid content] is 25 to 30%, and the proportion of the dispersant (4) [solid content] is 0.1%.

Among them, with the standard of paper (8), adjust the proportion of coffee grounds (1) to match Pulp (6), producing paper (8) that meets the needs.

Secondly, by the application of the dispersing agent (4), the coffee grounds (1) can be sufficiently mixed with the pulp (6) without being excessively dispersed and kept in a proper dispersed state.

In the above, the pulp (6) includes natural fibers and water, and the natural fibers include a proportion of [solid content] of 10 to 20% of long fiber [NBKP], a proportion [solid content] 20 to 25% of staple fiber [LBKP], proportion [solids] of 25 to 30% of ground fiber [BCTMP]; said additive (7), which includes a proportion [solids] of 5.5 % of dry strength agent, the proportion [solid content] is 0.7 to 0.8% of wet strength agent, the proportion of [solid content] is 0.04% of sizing agent, and the proportion [solid content] is 0.08%. The agent and the proportion [solid content] are 4 to 5% calcium carbonate.

Among them, for different application needs, fill the adjustment of the proportion of the pulp (6), with coffee slag (1), to produce the corresponding paper (8), expand the application range of the paper (8), provide different types of users Paper (8).

In the above, the washing machine (100) further comprises a disinfecting device (20); and the step of cleaning (B) further comprises: drying the coffee grounds (1) after washing, and simultaneously The step of sterilization.

Among them, through the application of the disinfection equipment (20), with the steps of drying and sterilizing, the coffee grounds (1) can be smoothly ground, and the problem that it is difficult to mix with the pulp (6) can be avoided, and the smoothness can be smoothly The pulp (6) is mixed, and at the same time, the coffee grounds (1) can be prevented from being moldy, which affects the application of the paper (8).

In the above, in the recovery step, the coffee grounds (1) can be one of the following: dried coffee grounds (1), undried coffee grounds (1).

Among them, for different coffee slag (1) application requirements, when recycling, can be dried or not dried, the difference between the two is, coffee slag (1) after drying, It can be easily managed centrally and is suitable for mass production. Because there is no other liquid mixed in, the water circulation equipment (10) has a lower burden, but the storage management cost is higher, while the coffee grounds (1) are not dried and can be quickly produced. In medium and small quantities, because of the incorporation of other liquids, the water circulation equipment (10) has a higher burden, but has no storage burden.

The structure, features and effects of the present invention are described in detail above with reference to the embodiments shown in the drawings. However, the above description is only the preferred embodiment of the present invention, but the present invention does not limit the scope of implementation as shown in the drawings. Modifications in accordance with the meaning of the present invention are intended to fall within the scope of the invention as long as they are within the scope of the invention.
