First, pretreatment facilities are described.

Pretreatment facilities are those that pre-process animal and plant by-products before mixing them with functional feed ingredients.

Pretreatment facilities of the present embodiment is the input hopper 110, the crusher 120, the primary separator 130, the pressing press 140, the storage tank 150, the vacuum dryer 160, the secondary separator 170, It is made of a mill 180.

The input hopper 110 is for injecting animal and vegetable by-products, has a capacity of about 20 m ³ , and is made of stainless steel in a completely sealed type.

The shredder 120 automatically shreds the flora and fauna by-product supplied from the input hopper (110).

The primary separator 130 selects various foreign matters contained in the flora and fauna by-products passed through the shredder 120.

The pressing press 140 depresses and dehydrates the flora and fauna by-products passed through the primary sorter 130. Therefore, the liquid material is discharged and dehydrated from animal and vegetable by-products by the compression dehydration process of the pressing press 140, and the liquid material is transferred to a water treatment facility described later and treated.

Compression press 140 is maximized the efficiency of dehydration and desalination using the principle of the juicer as shown in FIG.

4A is a plan view of the pressing press, and FIG. 4B is a front view of the pressing press.

As shown in FIG. 4, the pressing press performs a pressing process by a pair of rotating rods 141 and 142 provided with screws 141a and 142a, respectively.

That is, each of the rotating rods 141 and 142 increases in diameter from right to left with reference to FIG. 4. Therefore, the animal and vegetable by-product injected from the upper right side is moved from the right to the left by the rotation of the pair of rotating rods (141, 142) provided with the screws (141a, 142a) to be rotated by the drive of the motor 143, the process Since the diameter of the rotating rods (141, 142) is increased by the rotating rods (141, 142).

A pair of rotating rods (141, 142) provided with screws (141a, 142a) is wrapped by a screen (not shown) formed with pores, the liquid material generated by the compression is passed down the screen (not shown) After that, it is sent to a water treatment facility.

The animal and vegetable by-products that have been pressed are crushed again by the crusher 144 provided at the rear of the apparatus. Shredder 144 is a belt coupled to the motor 145 is rotated.

As described above, the pressing press 140 may be operated automatically and continuously, and thus, easy to manage and minimize the number of working personnel.

Animal and animal by-products that pass through the pressing press 140 are stored in the storage tank 150.

To this end, this embodiment is to provide two storage tanks 150 having a storage capacity of 15m ³ .

Next, the animal and vegetable by-products are dried in a vacuum while passing through the vacuum dryer 150 to reduce the moisture contained therein.

The vacuum dryer 150 injects the flora and fauna by-products in a sealed space and then dries the flora and fauna by-products from the outside in a vacuum. Therefore, the vacuum dryer 150 is operated batchwise. In addition, in this embodiment, the vacuum dryer 150 is provided with two, each group has a processing capacity of 9m ³ .

The vacuum state above and below means a pressure state below atmospheric pressure.

Figure 5a is a conceptual diagram for showing the internal structure of the vacuum dryer, Figure 5b is a conceptual diagram for showing the state of the steam supply provided on the outer surface of the vacuum dryer.

The vacuum dryer 160 is a cylindrical container lying horizontally is a main body, the inside of the main body is provided with a rotatable rod 161 rotatably provided with a plurality of wings (161a). In addition, the outside of the vacuum dryer 160 is provided with a steam supply unit 162 made of a steam supply pipe and a heat insulating material surrounding the same, so that the heat generated from the steam supply unit 162 heats the interior of the vacuum dryer 160.

Therefore, when animal and vegetable by-products are introduced from the upper left of the vacuum dryer 160, the inside of the vacuum dryer 161 is made into a vacuum state, and then the rotating rod 161 of the vacuum dryer 160 repeats the forward and reverse rotations. Accordingly, the wings 161a provided on the rotating rod 161 are repeatedly rotated forward and reverse to be dried by heat supplied from the outside while repeating the right and left movements of the flora and fauna by-products.

When the vacuum drying is completed, the animal and vegetable by-products are moved to the right side by the forward rotation of the rotary rod 161 and discharged to the bottom to complete the vacuum drying of one batch.

At this time, the air containing the odor generated by the heat drying is sent to the heat exchanger 410 for cooling of the atmospheric treatment facility.

As such, the vacuum dryer 160 has a kind of secondary crushing effect while minimizing the destruction of nutrients through vacuum drying.

Animal and vegetable by-products that passed through the vacuum dryer 160 are removed from the secondary sorter 170, and the like.

Animal and vegetable by-products passed through the secondary sorter 170 is finely crushed by the mill 180, thereby maximizing the efficiency as a feed through the production of a raw material having a fine grinding and even particles.

The grinder 180 of this embodiment is demonstrated by FIG.

6A is a conceptual plan view of the present grinder, and FIG. 6B is a conceptual front view of the present grinder.

The basic structure of the pulverizer is composed of a rotating shaft 183 driven by a motor 181, and a plurality of disks 185 in which one end of a plurality of hammers 182 are rotatably coupled along an edge thereof. The disk 185 is coupled to the rotation shaft 183 side by side along the longitudinal direction of the rotation shaft 183. In addition, a semi-cylindrical screen net 184 is provided at the lower portion of the rotating part including the rotating shaft 183, the disk 185, and the hammer 182.

delete

Therefore, when animal and vegetable by-products are introduced from the top, the rotating shaft 183 and the disk 185 provided thereon are rotated by the driving of the motor 181, and one end of the disk 185 is rotatable in accordance with the rotation of the disk 185. The combined hammers 182 are rotated upright by centrifugal force, and thus, only the flora and fauna by-products are crushed to a predetermined size or less and passed through the screen net 184 to be discharged downward.

The animal and vegetable by-products completed by the grinding step are packaged and transferred to the feeder.

Next, the feed establishments will be described.

Feeding facility is a facility that mixes pre-processed animal and vegetable by-products with functional feed materials to be used as feed.

Functional feed materials are made from grains such as corn, sorghum, wheat, and barley, salts such as soybean meal with vegetable oil, lysine, fishmeal, fish juice, fats and oils, or a mixture of them according to the required feed function. Compound feeds and the like can be used.

In this example, about 10 kinds of feed materials were introduced as functional feed materials.

The pretreatment facility of this embodiment consists of an input hopper 210, a mixing dryer 220, a sorter 230, a grinder 240, a storage tank 250, an automatic packaging machine 260.

First, the pre-treatment of animal and vegetable by-products and functional feed material is added to the input hopper 210.

The materials introduced into the input hopper 210 are mixed with each other while drying in a vacuum while passing through the mixing dryer 220.

Like the vacuum dryer 150, the mixed dryer 220 is dried while uniformly mixing the animal and vegetable by-products and the functional feed material with heat supplied from the outside in a vacuum state after the animal and vegetable by-products and the functional feed material are put in a closed space. Therefore, the mixing dryer 220 is operated in a batch. The basic structure of the mixing dryer 220 is the same as the structure of the vacuum dryer 150 shown in FIG. However, the mixing dryer 220 also has a function of maximizing the mixing and adsorption of animal and vegetable by-products and functional feed materials.

The mixer dryer 220 is dried to have a moisture of about 10% as a whole.

The air containing the odor generated in the mixing dryer 220 is sent to the cooling heat exchanger 410 of the atmospheric treatment facility.

The mixed feed drying material in the mixer dryer 220 passes through the sorter 230, and the contaminants are sorted in the third and naturally cooled.

The feed material passed through the sorter 230 is pulverized to a size that can be actually used in the feed material grinder 240, and the ground feed material is stored in the storage tank 250 and then packaged and shipped from the automatic packing machine 260.

Next, the water treatment plant of the present embodiment will be described.

This water treatment facility is a facility for separating the solids from the liquid material generated by dehydration in the pressing press 140 and reprocessing the solids in the pretreatment facility.

This water treatment facility is largely composed of a storage tank 310, the decanter 320, the centrifuge 330, the storage tank 340.

Storage tank 310 is for storing the liquid material generated by the dehydration in the pressing press 140.

Decanter (320, Decanter) is for receiving the liquid material of the storage tank 310 to separate the solids and the separation liquid therefrom.

Decanter 320 allows processing of about 8 tons of liquid material per hour.

The basic structure of the decanter 320 is a kind of centrifugal separator. The centrifugal force is applied to a processed material introduced into a rotating cylinder that rotates at a high speed to quickly settle the solid by using a specific gravity difference between the liquid and the solid, thereby maintaining a constant speed difference with the rotating cylinder. While the solids settled on the inner surface of the rotating tube by the rotating screw conveyor while transporting to the solids discharge port is dehydrated and discharged from the conical inclined portion, the supernatant is discharged to the separation liquid outlet through the spiral channel of the screw conveyor.

As described above, when the solids and the separation liquid are separated from the decanter 320, the solids are sent to the storage tank 150 of the pretreatment facility and introduced into the vacuum dryer 160, and the separation liquid is again secondary in the centrifuge 330. Are separated.

The solids separated from the centrifuge 330 are also sent to the storage tank 150 to be introduced into the vacuum dryer 160, and the separated liquid separated in the second storage is stored in the storage tank 340.

Separation liquid stored in the storage tank 340 may be reused for the entire amount of consignment treatment or other uses.

As described above, this embodiment separates solids quickly and efficiently through two centrifugal separations, and in particular, maximizes efficiency by selecting primary centrifugation by decanter and secondary centrifugation by general centrifuge. I'm making it.

Next, the air processing facility of this example is demonstrated.

This atmospheric treatment facility is a facility for treating air containing odor generated from various devices.

The present air treatment facility is mainly composed of a heat exchanger 410 for cooling, a wet scrubber 420, a first bio tank 430, and a second bio tank 440.

Since the air containing the odor collected by the vacuum dryer 160 of the pretreatment facility and the mixing dryer 220 of the feeder facility has a high temperature, the air temperature is about 20 ° C. to 30 ° C. through the cooling heat exchanger 410 first. Lower to 占 폚.

As such, the air passing through the cooling heat exchanger 410 and the air generated from various devices are first subjected to a water scrubber 420.

In this way, the collection of air containing the odor is a technique generally performed by the arrangement of the duct and the pump, so a separate description is omitted.

The wet scrubber 420 sprays particulate water into a space through which the air containing the malodor passes, so that the water-soluble malodor is primarily removed.

Air passing through the wet scrubber 420 flows into the first bio tank 430.

The first bio tank 430 is provided with a detachable diaphragm 431, 433, 435 formed in a plurality of holes at a predetermined interval (about 1M in the present embodiment), the oyster on the upper portion of the diaphragm (431, 433, 435) Biofilters 432, 434, and 436, which are loaded by mixing shells, wood chips, and baked ocher grains, are provided, respectively. In addition, the biofilters 432, 434, and 436 may intentionally plant aerobic microorganisms.

Therefore, the air introduced into the first bio tank 430 passes through the biofilter 432, the diaphragm 431, the biofilter 434, the diaphragm 433, the biofilter 436, and the diaphragm 435 in this order. After it is discharged.

If there are no diaphragms 431, 433, 435, the loaded biofilters 432, 434, 436 are excessively pressed by its own load, and thus, smooth air flow is not possible. Thus, diaphragms 431, 433, 435 are provided to prevent this. It is also very easy to replace each biofilter 432, 434, 436 by diaphragms 431, 433, 435 when exchanging each biofilter.

The bio filter 432 located at the top was loaded by only half the height of the space separated by the diaphragm 431 to allow air to pass through the entire cross section of the filter 432.

Air passing through the first bio tank 430 flows into the second bio tank 440.

The second bio tank 440 is provided with a detachable diaphragm (441, 443) formed with a plurality of holes at a predetermined interval (about 3M in this embodiment), the bio on the upper portion of the diaphragm (441, 443) Filters 442 and 444 are provided.

The biofilter 442 is a biofilter loaded with a mixture of oyster shells, aerobic microorganisms, and baked ocher grains. The biofilter 444 is a biofilter loaded with a mixture of rice straw and wood chips.

Therefore, the air introduced into the second bio tank 440 passes through the diaphragm 441, the biofilter 442, the diaphragm 443, and the biofilter 444 and is discharged to the atmosphere.

On the other hand, at the bottom of the first bio tank 430 and the second bio tank 440, the liquid material generated as the air containing the odor passes through the biofilter falls, the liquid material is used as a raw material of the liquid fertilizer, The liquid material generated in the first bio tank 430 may be sprayed over the entire surface of the bio filter 444 at the upper portion of the second bio tank 440 to promote growth of microorganisms.

In addition, although only one first bio tank 430 and only one second bio tank 440 are illustrated in FIG. 7, this is only an example, and several bio tanks are connected in series. It may be used, and a fan or the like may be provided for the movement of air.

The above embodiments are merely preferred embodiments of the present invention, and the technical spirit of the present invention may be variously modified or adjusted by those skilled in the art. Such modifications and adjustments fall within the scope of the present invention if they use the technical idea of the present invention.

As described above, the present invention can provide a new system and method for feed-processing animal and vegetable by-products such as food waste to be reused as resources to prevent environmental pollution and promote recycling of resources.

In addition, the present invention, by completely treating the liquid residue and odor generated by the treatment of animal and vegetable by-products through a water treatment facility and an air treatment facility, it is possible to block secondary environmental pollution.
