Sawdust for barn rugs containing disinfectant and its manufacturing method {Stable-rug Sawdust Containing Disinfectant And Manufacturing Process Thereof}

The present invention relates to a sawdust for barn carpet containing a disinfectant for viruses and various bacteria, including foot-and-mouth disease. More specifically, this is a sawdust rug made of sawdust containing disinfectant, and the disinfectant stall is made to maximize the disinfecting effect of the disinfectant-containing sawdust used as the yard by controlling the rate of release of the disinfectant. It relates to a sawdust for rugs and a method of manufacturing the same.

In recent years, livestock farmers have been affected by foot-and-mouth disease and avian influenza, and livestock farms are becoming more and more important. . Foot-and-mouth disease, which has been the most problematic in recent years, is an acute infectious disease of highly infectious cow products that are infected with the foot-and-mouth disease virus, which causes blisters around the mouth or hooves of two hoofs, pigs, etc. Is the first type of viral forensic infection. The incubation period for cows is 3-8 days, with a high fever (40-41 ℃) at the beginning, bleeding without sacrificing feed, swelling with mixed bubbles, blisters between acute stomatitis, canning and pain I get sick and die.

There is no special treatment, and if foot-and-mouth disease occurs, quarantine must be thorough and all cattle in contact with infected cattle must be incinerated or buried. On the other hand, the government has recently made a move to change the prevention strategy of foot-and-mouth disease from massive killing to active pre-vaccination along with killing. However, there is a possibility that antibodies will not form even if the vaccine is inoculated, and when the vaccine needs to be carried out twice, the importance of prevention activities such as self-disinfection of livestock farms is increasing. to be.

On the other hand, if foot-and-mouth disease occurs, the influx and outflow of feed, manure, etc., including sawdust for barn litter, which can easily spread the foot-and-mouth virus is completely blocked. During foot-and-mouth disease outbreaks, the supply of sawdust and the like becomes difficult, which makes it difficult to process livestock meal. In addition, livestock farms have used livestock rugs to protect livestock from cold floors, and have used livestock as organic compost. Not only do they protect their livestock from the cold, but they have no choice but to deal with livestock.

On the other hand, sawdust, rice husk, bark, rice straw and the like has been utilized as a livestock litter. By controlling moisture and carbon ratio, and supplying oxygen appropriately, aerobic fermentation process decomposes organic matter, eliminates bad smell and pathogens, and makes organic fertilizer that is easy to handle by reducing volume and weight. It becomes usable. The sawdust used for processing livestock is recommended to use pine sawdust from the National Livestock Research Institute. Pine sawdust has a high effect of soft fiber and antibacterial and deodorant by rosin and essential oils. This is because it has an excellent effect on stress relief (sedation). In particular, it is widely used in milking parlors, cattle, pigs, poultry and organic fertilizers. In addition, there are hundreds of thousands of pores per sawdust particle, so it has excellent absorption ability, and the pine's unique porous structure and many kinds of beneficial natural ingredients prevent the onset of parasites in livestock.

Considering that the outbreak of foot and mouth disease is usually cold winter, it is possible to protect the livestock house from the cold bottom cold and to be thoroughly sterilized to prevent the invasion of various viruses and bacteria including foot-and-mouth disease. There is a need for livestock rugs containing disinfectants.

Although it is possible to temporarily disinfect sawdust to be supplied to farmers using a disinfectant solution, a long-term disinfecting effect can be generated when most of the disinfectant is removed in the process of drying sawdust after disinfection. Since then, there is a need to supply disinfectant-containing sawdust, which can exert a certain degree of disinfection effect.

As related related arts, a livestock pallet composition and its pallet are disclosed in Korean Patent Publication No. 10-2006-0081473. The prior art is prepared by containing a disinfectant in the livestock pallet, but the disinfectant component contained in the pallet disappears in most of the distribution process such as transportation and storage after manufacturing, there is a disadvantage in that the lasting effect of the disinfecting pallet is very poor.

On the other hand, US Patent No. 5110785 (COMPOSITION OF MATTER AND METHOD OF MAKING) discloses that when the sawdust is treated at a high temperature, the structure in the sawdust is changed to a lipophilic structure and used for absorbing the oil floating on the water It is.

Hereinafter, a method for producing a sawdust for disinfectant barn carpet according to the present invention will be described in detail step by step.

1.Step 1: removing foreign substances in sawdust

Step 1 is a step of removing foreign matter remaining in sawdust which is a by-product generated during cutting and processing in logging or sawmill.

The sawdust is passed through a filter separator with a 10 to 100 mesh filter screen at 50 to 200 rpm to remove foreign substances such as bark and stones, sand and nails remaining in the sawdust.

Here, the sawdust is recommended as pine sawdust from the National Livestock Research Institute, the raw material of sawdust is used pine, the moisture content within 35 to 55%, the particle size of 0.1 to 3mm range. This size is best used for rugs.

On the other hand, the raw wood of sawdust can be used to select any one, regardless of the type of wood, it is preferable to use pine. In case of using imported sawdust, it is used to prevent the influx of external infectious diseases.

Whole chaff may be mixed with the sawdust added to the dryer in step 1. This is when the supply and demand of sawdust is insufficient to mix the whole rice husk into sawdust.

It further comprises 50 parts by weight of whole rice hulls with respect to 100 parts by weight of sawdust. At this time, the whole rice husk is bad in its natural state in the non-pulverized state, it is preferable to use the ground crushed because it gives a stimulus and wounds to the body and feet of the livestock when used for the rug of the barn.

The whole rice husk is obtained as a by-product from rice milling plant or rice grain processing plant. The whole rice husk is put into water and washed to remove foreign substances such as dust, and then picked up, dried, put into a grinder, and ground to 100 to 300 mesh.

2. Step 2: Drying Sawdust

Step 2 is a step of drying the sawdust of step 1.

The sawdust is put into a tumble dryer, dried by first applying heat of 500 to 600 ° C, and then dried by lowering the temperature to 80 to 120 ° C. And the rotary dryer is rotated at a speed of 10 to 100rpm, so that the heat is evenly supplied to sawdust.

Here, by drying the sawdust to a high temperature, it is expected that the structure of the sawdust will be changed to a structure that can contain a large amount of polymer and disinfectant components.

The rotary dryer operates until the moisture content of the sawdust is within 5 to 15%, the drying time depends on the moisture content of the sawdust.

On the other hand, the drying of the sawdust mixed with the whole rice husk of step 1 is made in the same manner as above, wherein the moisture content means the total moisture content of the whole rice husk and sawdust.

3. Step 3: Remove the Disinfectant Joe  step

Step 3 is to prepare a disinfectant to be stirred together with the sawdust of step 2. The disinfectant may be prepared in advance, and the preparation step may be omitted, and the disinfectant may be used immediately.

The effective iodine content in the iodine for disinfectant solution is varied, but the effective iodine content of 2.75% was used in the present invention.

Aldehyde fungicides include formaldehyde, glutaraldehyde and the like. Formaldehyde is a colorless irritant liquid used for the preparation of preservatives and tissue specimens. It is used for fumigation or spray disinfection. In the case of fumigation of buildings, it is usually used by mixing potassium permanganate and formaldehyde solution in a ratio of 3: 5. have. 40% aqueous formaldehyde solution is called formalin and it is used for apparatus and indoor disinfection because of its skin irritation and smell.

Glutaraldehyde is used as a disinfectant for foot-and-mouth disease due to its low irritation to skin and mucous membranes and susceptibility to a wide range of pathogenic microorganisms compared to formaldehyde. Sterilization is maintained even in the presence of protein (eg serum), and sterilization is strong in alkaline. In particular, it is most effective when used as a 2% buffer solution of ph7.5 ~ 8.5. In aldehyde-based fungicides, it is preferable to use glutaraldehyde which is less irritating to the skin of livestock.

The disinfectant of the quaternary ammonium-based surfactant according to the present invention is one in which four hydrogens present in ammonium (NH ₄ ) are repaired with organic molecular groups, which are white gels, and are soluble in water. Quaternary ammonium surfactants include cetridemide and benzalkonium chloride. Quaternary ammonium surfactants, especially benzalkonium chloride, are already widely used as disinfectants. The quaternary ammonium surfactant according to the present invention preferably uses benzalkonium chloride.

On the other hand, the water-soluble polymer means a polymer that can exist in a dissolved state in water, as well as a polymer that can be dissolved in water at room temperature, as well as a polymer that shows the dissolution stability to water at room temperature after being dissolved in high temperature water, used It is not well dissolved in water as a solvent, but includes all polymers that can be dissolved in water after dissolving the polymer in an intermediate solvent such as an appropriate amount of ethanol to dissolve in water. Preferably, it includes a polymer that can be dissolved in water at room temperature. The water-soluble polymer according to the present invention is sufficient if it can be dissolved in water and can form a film layer after mixing in sawdust. The content of the water-soluble polymer is sufficient to form a film as the water in the pesticide vaporizes, and preferably contains 10 to 20 parts by weight based on 100 parts by weight of sawdust.

As the water-soluble polymer, various kinds of water-soluble polymers such as natural polymers, semisynthetic polymers, and synthetic polymers may be used. Natural polymers include gelatin, pectin, dextran, hyaluronic acid or salts thereof, collagen, agar, arabia gum, residue rubber, Gums such as acacia rubber, Karaya gum, Tragacanth gum, Guar gum, starch, carrageic acid, alginic acid, sodium alginate ( Sodium alginate) and the like, but is not limited thereto. In particular, natural water-soluble polymers may additionally play a role as a nutrient for crops depending on the type of insecticide action. In addition, the semi-synthetic polymer is methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, sodium carboxy methyl cellulose, soluble starch, dextrin ( Dextrine), carboxymethyl starch (Carboxy methyl starch), dialdehyde starch (Dialdehyde starch) and the like can be used, but is not limited thereto.
