Description

Fillet manufacturing method using sawdust

The present invention relates to a method for producing a fillet using sawdust, and in more detail, by adding starch instead of glue to sawdust and compression molding, it is possible to use the produced product as feed or compost for livestock.

Conventional products using sawdust have been used in many places to manufacture the necessary products around the living to effectively handle the sawdust, which is a float generated when processing wood.

As described above, the products used in living surroundings using sawdust include charcoal, which is frequently used in roasting houses and other fire-fighting businesses, as well as compressed plywood (MDF), partitions, and office equipment. Household goods are spread around us.

However, sawdust is a floating material that occurs while processing the wood, and contains a certain ratio (about 54%) of the water contained in the wood. This is too much moisture to manufacture products using sawdust, so compressing sawdust to remove moisture at the same time to heat about 200 ℃ to serve to increase the rigidity of sawdust and evaporation of moisture.

In addition, the compression of only sawdust did not have high strength, the utilization as a product was not high. In order to increase the cohesion of sawdust to have a suitable strength as a product to increase the strength by adding glue in the process of compressing sawdust.

However, when using the glue as described above is not possible to use for livestock feed or compost costs, the use of the industrial is limited. In addition, the sawdust does not decay due to microorganisms when discarded after the end of the life of the product, the sawdust does not rot no matter how much time has passed, causing another contamination. In addition, when incineration of waste, glue is a chemical reaction to generate toxic gas, which is also a major contributor to environmental pollution.

In addition, the range of use of sawdust is not a product having a certain shape as described above, but sawdust is also used in many places where compost is produced using manure while eliminating bad smells caused by the excretion of livestock generated in livestock farms. .

Sending wastes from livestock to rivers can cause serious pollution to the environment and can cause serious social problems. However, in order to prevent this, it is necessary to have a purification facility, which is very expensive, which causes a considerable burden on the farm.

In order to solve the above problems, by placing sawdust on the bottom of the barn, the excretion of livestock reacts with the sawdust to remove odors, and adds sawdust after fermentation for a certain period of time to produce compost instead of chemical fertilizer. In addition, when applied to the soil not only prevents the acidification of the soil, but also helps the growth of the crop has brought many advantages of the farm.

However, in spite of the above advantages, the reason for reluctant use in livestock farms is that the cost of transporting sawdust is difficult due to the difficulty of transporting sawdust, and the production cost is too high to produce sawdust as it is difficult to manage. There was a downside to falling.

In the present invention, the medium for fixing sawdust in the compression process of sawdust is solidified by using starch instead of glue, or by compressing only sawdust without adding additives so that sawdust can be used according to the purpose of use after transportation. In addition to reducing losses incurred, the wider range of uses has been achieved, allowing a wider range of resources to be recycled.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

In the manufacturing of the sawdust pellet 10 by adding starch at the same time to remove moisture by using heat in the process of compressing sawdust in order to recycle the sawdust generated by the processing of the wood;

Since the shape of the pellet 10 may have any shape of a polygonal column including a columnar, a square column, and the present invention will be described based on the hexagonal column.

The pellet 10 using the sawdust removes the water (about 54%) contained in the sawdust using heat (about 200 ° C.) after supplying sawdust generated from the wood to the compressor. In this process, starch is added to increase the cohesion of sawdust, thereby facilitating the solidification of sawdust, thereby facilitating manufacture.

In addition, by forming a hole 20 in the central portion of the pellet 10 to ensure that the same amount of water evaporates at the same time the inner portion and the outer portion at the same time during the removal of the moisture of the sawdust uniform water after the manufacture of the pellet 10 Let the distribution of.

Since the production of the pellet 10 using the high temperature as described above is also made with the action of sterilization when used as a feed for livestock there is no need to separate sterilization.

The wood used as the material of the pellet 10 should use miscellaneous goods of the non-transmissive series except Nawang. In addition, the imported wood is imported into the country by adding a large amount of preservatives, so when the livestock are ingested such trees cause a lot of problems, so the use of wood with preservatives is limited.

Referring to the preferred action of the prepared pellet 10 as follows.

When using the pellets 10 for livestock feed, when a certain amount of the pellets 10 are immersed in water, the sawdust, which is fixed by heat and starch, is decomposed and has the same shape as sawdust before processing. In addition, in order to be used for feed, it can be said to be valuable as a feed only after the decomposition is completed within 30 minutes of starting the decomposition in water.

According to the test value when the pellet 10 was decomposed in water, the volume change rate was 2 times after 10 minutes, 3 times after 30 minutes, and 4 times after 1 hour. Thus, when water penetrates, the pellet 10 is completely decomposed after about 30 minutes, so it is not only valuable as a feed, but also the volume of the pellet 10 increases several times when decomposed in water. Sawdust can be taken, so there are many economic benefits for the user.

In addition, when used in a livestock farm or a compost manufacturing company, by simply throwing the pellet 10 where the animal waste is accumulated, the pellet 10 reacts with the water contained in the animal waste to decompose and combine with the excrement. This not only eliminates bad odors, but also allows for easy post-treatment of feces, reducing waste of manpower in livestock farms, and the compost manufacturing company only needs to throw the pellets 10 into the composting process, so sawdust hoppers This does not require heavy equipment used to supply the equipment, thereby simplifying the equipment and equipment.

In the case of manufacturing the pellet using the sawdust prepared as described above, the freight cost is reduced compared to transporting sawdust due to the reduction of the volume, solidifying sawdust using starch or using only sawdust without adding additives As it solidifies, it is possible not only for industrial use but also for feed of livestock, and it is possible to be naturally decomposed, thus preventing environmental pollution, and there is various effects such as cost reduction due to the simplification of the facility because no separate sterilization process is required.
