BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view for explaining a soil used for seedling growth. FIG.

As shown in Fig. 1, the soil 100 is used for seedling cultivation. The topsheet 100 is divided into a topsheet 110 and a topsheet 120. In order to grow seedlings, the topsheet 100 is first loaded on the topsheet, and the seeds 150 are sprayed onto the topsheet 100 for the topsheet. Then, the seed 150 is covered with the soil cover 120. The topsheet 110 and the topsoil 120 are the same in that the seeds 150 serve to supply nutrients until they grow to some extent. However, as the seeds 150 germinate and grow, (110) plays a major role in root growth, and the soil layer (120) plays a main role in allowing seeds to germinate and grow stalks. Conventionally, the same soil is used for the soil base soil 110 and the soil base soil 120. In order to grow more excellent seed grains, the soil base soil 110 and the soil base soil 120, .

FIG. 2 is a flowchart illustrating a method of manufacturing a granular soil for a slab and a granular soil for a soil according to an embodiment of the present invention.

Referring to FIG. 2, one embodiment of a method for producing a granular soil for a slab and a granular soil for a soil according to the present invention comprises a raw material preparing step (S210), a mixing raw material generating step (S220) (S230), a coating and hot air drying step (S240), and a particle size separation step (S250).

The preparation of the raw material (S210) is a step of preparing zeolite and diatomaceous earth to be the raw materials of the granular soils.

Zeolites are alkaline and alkaline earth metal silicates of aluminum hydrate. It is white or translucent in color. Zeolite is also called zeolite, meaning 'boiling stone'. The zeolite makes a three-dimensional skeletal structure and has pores inside, which contain water molecules and exchangeable cations. The water molecules are easily removed by heating at a relatively low temperature, but the skeleton of the structure does not change, so it absorbs water vapor in the air and replenishes the water again. Zeolite has cation exchange properties, adsorption and molecular sieve properties, catalytic properties, dehydration and reabsorption properties, and when used as a soil for seedlings, it does not leach easily and does not leach out slowly, so there is no nutrient deficiency and it helps strengthen the soil after migration. .

Diatomaceous earth is mainly composed of silicic acid, white or grayish white. Diatomaceous earth is mostly amorphous silica, physicochemically stable inorganic, porous, light, absorbent and water-holding.

In order to prepare a zeolite raw material, zeolite raw material is firstly pulverized in a pulverizer. The primary pulverization is performed so that the diameter of the zeolite ores is 100 mm or less. Next, the zeolite raw material on which the primary pulverization has been carried out is put into a pulverizer and then subjected to secondary pulverization. The second milling is carried out so that the diameter of the zeolite ore is 15 mm or less. The zeolite raw material having a particle size of 3 mm or less and a moisture content of 10% or less and a pH of 6.0 to 8.0 is stored in a silo. Prepare diatomaceous earth materials in a similar way. First, the diatomaceous earth ore is put into a pulverizer and firstly pulverized. The primary pulverization is performed so that the diameter of the diatomite ore is 100 mm or less. Next, the diatomite raw material subjected to the first pulverization is put into a pulverizer and is secondly pulverized. The secondary pulverization is performed so that the diameter of the diatomite ore is 15 mm or less. Secondly, diatomaceous earth ore is sieved to store diatomaceous earth materials having a particle size of 3 mm or less, a moisture content of 20% or less, and a pH of 3.5 to 4.5 in another silo.

The use of zeolite and diatomaceous earth as pH regulated zeolite as raw materials makes it possible to easily produce granular soils having pH suitable for germination of seedlings. In addition, if only zeolite and diatomaceous earth are used as raw materials and a material such as vermiculite is not used as a raw material, the process is reduced, and there is no dust generation, and the working efficiency is increased. In addition, since no separate organic material is used as a raw material, the storage period is significantly increased compared to the conventional soil.

The mixed raw material generating step (S220) is a step of mixing the zeolite raw material prepared in the raw material preparing step (S210) with the diatomaceous earth raw material. The mixed raw material is produced by mixing 70 to 80% by volume of a zeolite raw material having a particle size of 3 mm or less and a pH of 6.0 to 8.0 and 20 to 30% by volume of a diatomaceous earth raw material having a particle size of 3 mm or less and a pH of 3.5 to 4.5 in a pedal mixer.

The granular soil preparation step S230 is a step of preparing the granular soil by injecting the mixed raw material produced in the mixed raw material generating step S220 into the fan granulator together with the nutrient solution and water. The fan granulator is a pan type granular granulation granulator which generates centrifugal force while the fan rotates to mix the raw material, nutrient solution, and water injected into the fan granulator to form granular soil. At this time, step S230 is performed so that the prepared granular soils have a particle size of 0.5 to 8 mm and a pH of 4.5 to 6.0. The granular soils prepared contain about 30% of water. The nutrient solution is a liquid containing various nutrients for growth of seedlings, and may contain ammonia nitrogen (NH 4 -N), effective phosphoric acid (P 2 O 5 ), and the like.

The coating and hot air drying step S240 is a step of coating the surface of the granular soil prepared in the granular soil preparation step S230 with zeolite powder and drying with hot air. The coating and hot air drying step S240 may be performed in a facility in which a drum assembly and a rotary drying function are combined as a granulator in which a drum is rotated. The granular soils and the zeolite powder produced in the granular soil preparation step (S230) are introduced into a facility having a combination of a drum granulator and a rotary drying function, and the granular soil and the zeolite powder are mixed by using hot air of 300 to 400 ° C When the granular soils are dried for about 10 minutes, the granular soils are coated with zeolite and dried. At this time, the zeolite powder may have a particle diameter of 150 to 200 mesh. 'Mesh' is a unit of the number of sieves in a sieve having a size of 1 inch and 100 meshes indicates a size of particles having a size equivalent to 100 sieves in 1 inch 2 . When the coating and the hot air drying step (S240) are performed in this manner, the moisture content of the granular soils containing about 30% of water can be adjusted to 20 to 22%, and the coating and the hot air drying process The surface coating improves the strength of the granular soils as well as sterilizing and disinfecting the granular soils by hot air. At this time, the grain size of the granular soils is about 0.1 to 8 mm.

The granule separation step S250 is a step of granulating the granular soils obtained by coating the surface with zeolite and drying with hot air in the coating and hot air drying step S240 with granular soils for ground cover having a particle size of 1 to 2.5 mm and granite soils having a particle size of 2.5 to 5.5 mm And separating into granular soils. That is, the granule separation step S250 is a step of separating the granular soils having a size of 0.1 to 8 mm into granular soils suitable for use as a soil for grounding and granular soils suitable for use as a mat for a mat, One granularity sorting step (S260) and a second granularity sorting step (S270).

The first granularity selection step S260 is a step of selecting a granular soot having a particle size of 1 mm or less among the granular soils having a particle size of 0.1 to 8 mm and having a surface coated with zeolite in a coating and hot air drying step S240, And removing the granular soils. That is, the first particle size selection step S260 is a step of separating the granular soils having a particle size of 0.1 mm to 8 mm and the granular soils having a particle size of not less than 1 mm and the granular soil having a particle size of 5.5 mm or more, Is the step of leaving only the granular soils. At this time, the granular soils having a particle size of 1 mm or less removed are transferred to the belt conveyor and re-introduced into the raw material. The granular soils having a particle size of 5.5 mm or more removed are transferred to a pulverizer and re-pulverized. The first grain size selection step S260 may be repeated one or more times so that only granular soils having a grain size of 1 to 5.5 mm remain.

The second granularity selection step S270 is a step of selecting granular soils having a particle size of 1 to 5.5 mm selected through the first granularity selection step S260 to a granular ground for a ground having a granularity of 1 to 2.5 mm and a granular ground having a granularity of 2.5 to 5.5 lt; RTI ID = 0.0 > mm. < / RTI > When a granular soot having a small particle size (1 to 2.5 mm) is used as a soil sole, a granular soot having a large particle size (2.5 mm) is used as a soil sole, or a granular soot having a small particle size (1 to 5.5 mm) Is superior in water permeability as compared with the case of using as a soil for soil, and there is little occurrence of excavated seedlings, so that the defective rate of the matrix can be remarkably reduced. (1 ~ 2.5mm) granular soils can be used as a soil for a mat or a variety of granular materials (1.5 ~ 5.5mm) can be obtained by using granular soils having a large particle size (2.5 ~ 5.5mm) As compared with the case where the granular soils are used as the soil for the soaking, it is possible to provide a homogeneous soil for the soaking of the soaking basin. In addition, it is possible to manufacture both the granular soils for soil and the granular soils for a mat through the same particle size separation step, thereby reducing manufacturing costs.

The granular soils for soil and the granular soil for the soils separated through the granularity separation step (S250) are respectively stored in different silos. The granular soils for soil and the granular soils for the mat can pass through the particle size uniform device before being stored in the silo. The particle size uniforming apparatus is intended to have uniform particle size distribution and uniform pH and EC (electric conductivity) of granular soils for ground and granular soils for mat.
