Description

Method of manufacturing wood chips for landscaping and gardening using waste twigs

1 is a process diagram of the present invention.

The present invention relates to a method of manufacturing wood chips for landscaping and gardening using waste residue. More specifically, the waste residue is processed into chips or sawdust, heated, pressurized, sterilized and pesticides are treated with chemicals and then dried to manufacture wood chips for landscaping, or the ground sawdust is pressed into spherical or pellets, It relates to a method of manufacturing a wood chip for landscape by molding.

Conventionally, the waste residue is simply crushed and used as a landscaping material, but the landscaping material itself is not only a medium for habitation, but also a decomposition method of the landscaping material is so long that it cannot be expected as a fertilizer. will be.

Conventionally, the waste residue is simply crushed to be used as a landscaping material, but the landscaping material itself is not only a medium for habitation, but also the decomposition period of the landscaping material of this landscaping material is so long that it can be expected to play a role as a fertilizer. There is a problem such as not.

Accordingly, the present application is to produce a wood chip for landscaping and horticulture using waste residue. In order to solve the above problems of the invention, the present inventors processed the waste residue into chips or sawdust, and put it in a chemical treatment tank, and sterilized it at about 120 ° C. with steam, and then killed it at a pressure of 40 to 100 mmHg, and then soiled it. A product obtained by infiltrating chips or sawdust into a chip or sawdust after dehydration of a treatment solution composed of microorganisms, decomposition accelerators, compound fertilizers (NPK), insect repellents, inorganic adsorption and moisturizers, penetrants (alcohol), coloring agents, water, etc. Sawdust is compressed and molded into a sphere, pellets, etc. to obtain a product by vacuum drying.

However, in the present invention, the sawdust refers to a diameter of 10mm or less.

As the processing liquid of the chip and sawdust,

Aerobic Soil Microorganisms 0.1 ~ 15.0wt%

Degradation accelerator 0.001 ~ 0.01wt%

Compound fertilizer (N.P.K) 0.1 ~ 10.0wt%

Insect Repellent 0.1 ~ 5.0wt%

Inorganic adsorption and moisturizer 20 ~ 40.0wt%

Penetrant (alcohol) 5.0 ~ 20.0wt%

Dye 0.01 ~ 1wt%

It is made as a residual amount of water.

As the aerobic soil microorganisms, there are about 100 species such as cellulose monas, bacillus, aerobacteria, rizobium, azotobacteria, pseudomonas, and clostridium, and these strains can be used as products or cultured. In particular, Pit (Peat), which is a kind of active sludge, is largely present in Yeongdong, Gangneung, and Hadong provinces in Korea, and is composed of dark brown powder of over 80mesh.

Most of them are fermented at a high temperature (60 ~ 70 ℃) to decompose wood in a short time, or the decomposition rate is slow at room temperature, so that degradation occurs slowly for about 3 months to a year.

Therefore, by using one or two or more types of soil microorganisms and adjusting the amount of addition, the rate of degradation can be adjusted to the environmental conditions. In particular, when it is necessary to accelerate the decomposition, one or two or more inorganic acid metal salts such as ZnSO ₄ · 7H ₂ O, FeSO ₄ · 7H ₂ O, CuSO ₄ · 5H ₂ O, MgSO ₄ · H ₂ O, etc. By adding 0.01wt%, the rate of decomposition can be easily controlled.

The compound fertilizer mainly uses N.P.K synthetic fertilizer or organic compound fertilizer which is commercially available.

N (nitrogen): 5 ~ 20wt%

P (phosphorus): 5 ~ 40wt%

K (Potassium): 5 ~ 20wt%

Anything within the range of may be used and shall be fully water soluble.

In particular, the use of a liquid organic compound fertilizer is preferred, and its content is preferably 0.1 to 10% by weight.

Inorganic adsorption fixative is composed of water-soluble starch, hydroxy ethercellulose, gelatin, CMC and other degradable adhesives such as zeolite or aluminum silicate, which is composed mainly of hydrous silicate alumina. It is used to maintain adhesion and moisturizing power. The amount is used in the range of 5 to 30% by weight in the case of inorganic adsorption fixing agent, and 0.1 to 5% in the case of organic adhesive.

Dyes are oily or aqueous dyes. Green, blue, yellow, and white are dissolved in alcohol and added to the treatment solution. The amount of dye is 0.01 ~ 1wt%.

In this case, alcohol is used to reduce the surface tension of the treatment solution and to increase penetration and moisture evaporation into the chip or sawdust. The amount of alcohol is 5 ~ 20wt%.

For example, it will be described in detail as follows.

Example 1

The waste residue was processed into chips, 100Kg was placed in a treatment tank, and under pressure, sterilized and killed at 120 ° C. for 30 minutes, and then decompressed to 60 mmHg, and then the treatment solution of the following adjustment was added so that the chip was sufficiently submerged.

Cellulomonas 15Kg

Clitrizium 4Kg

Azotobacteria 11Kg

Feet (Active sludge) 50Kg

ZnSO ₄ 7H ₂ O 10ppm

_{K 2 SO 4 · 7H 2 O} 10ppm

CuSO ₄ · 5H ₂ O 10ppm

50Kg Compound Fertilizer (N: 20, P: 10, K: 10)

Zeolite 100Kg

Water Soluble Starch 50Kg

Naphthalate 12Kg

Methyl Alcohol 150Kg

Dye (japon blue) 3Kg

Water 555Kg

A total of 1000 Kg was prepared by mixing in a treatment liquid mixer. PH of the process liquid at this time was the range of 6.0-7.0.

Then, the chip and the treatment liquid were pressurized in the treatment tank to reach 3Kg / cm ² and maintained for 30 minutes, and then the pressure was removed, the treatment liquid was sent to the recovery tank, and the treated chips were transferred to a centrifugal degreaser tank to remove the liquid. The liquid was transferred to the treatment liquid recovery tank, the chip was transferred to a vacuum dryer, and the remaining moisture was vacuum-dried for about 30 minutes under reduced pressure at 70 ° C. and 60 mmHg, and then sealed and packaged under heat to obtain landscaping and gardening chips.

The moisture content of the chip at this time was 30 wt%.

Example 2

In Example 1, after replacing sawdust instead of chips and vacuum drying the residual moisture for 15 minutes in the vacuum drying process (at this time, the moisture content of sawdust was 50wt%), the spherical shape (diameter 30nm) and pellet (diameter) 20 nm, 50 nm in length) was processed in the same manner as in Example 1 except that the sawdust was transferred to a vacuum dryer to obtain a spherical and pellet gardening chips.

The landscaping wood chips manufactured in this way are beautiful in color and shape, and are used as a landscaping and gardening material for grass, roadside trees, gardens, or orchards. It is effective and also has an excellent effect of insect repellent, insecticides.
