BACKGROUND ART A manufacturing device and method for feedstuff made with food waste

The present invention relates to a single feed manufacturing apparatus capable of producing various types of single feed, and a method for manufacturing the same, wherein, in producing a single feed in which food waste is converted into animal feed, no leaching solution is discharged from one treatment tank A single feed manufacturing apparatus and a manufacturing method thereof, in which wet or dry high-nutrition single feed that is converted into a single feed in an untreated state can be manufactured, or a wet or dry low-nutritive feed that is converted into a single feed in a state in which the leaching liquid is discharged, and a manufacturing method thereof , It relates to a simple feed manufacturing apparatus and a method for manufacturing the same, which simplifies the apparatus, and furthermore exhibits energy saving and odor reduction effects, unlike the prior art in which a large number of devices must be provided in order to convert food waste into single feed.

Food waste has a bad odor and is difficult to treat, so if it is thrown away as it is, it has a serious adverse effect on the environment. Moreover, it was never desirable in terms of recycling waste resources as the nutrients of various components contained in the food waste were lost as they are. In this situation, as a method of recycling food waste in consideration of environmental pollution and economic value added, research on sweet feed in which food waste is used as feed for animals is emerging.

However, recently, a number of devices and methods for recycling such food wastes as single feed have emerged. However, when such food wastes are used as single feed, there is a problem in that the salt contained in the food waste must be removed. .

Korean Patent Registration No. 10-1074651, which is a prior art for converting food waste into single feed, will be reviewed. In the prior art, food waste is efficiently processed by collecting food waste and removing foreign substances mixed with food, and then continuously producing dry, wet, and liquid feed that can be fed to animals, etc. through an automated facility system. At the same time, it discloses technical features that can contribute to environmental conservation projects.

However, according to the prior art, it is necessary to go through a number of processes in converting food waste into a single feed, and furthermore, as the wet and dry feed is manufactured in separate processes, the process is complicated and requires a lot of facility investment. .

Furthermore, in recent years, a method of converting food waste into a simple feed for livestock such as pigs, as well as for dongae, which is strong in salt, has emerged. In other words, unlike the prior art in which the desorbent contained in the food waste is removed by dehydration in order to lower the salt level in the food waste, the nutrients of various components contained in the food waste are maintained without separating the desorbent. , a method of converting food waste into a simple feed for Dongae, etc., which is strong in salt, is emerging.

As food waste is converted into single feed in various forms and can be used as single feed for various animals, there is an urgent need for an apparatus or method for producing single feed that is efficient, energy-saving, and can simplify the process of making single feed.

2 is a flowchart schematically illustrating a method for manufacturing a single feed according to the present invention.

Hereinafter, preferred embodiments of the method according to the present invention will be described with reference to the accompanying drawings. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of the user or operator. Therefore, definitions of these terms should be made based on the contents throughout the present specification.

A simple feed manufacturing apparatus according to the present invention will be described with reference to FIG. 1 .

The apparatus for producing a single feed according to the present invention includes a food waste inlet pipe 100 , a treatment tank 200 , a desorbent solution outlet pipe 300 , and a vacuum pump 400 .

The magnetic separator 140 is positioned around the food waste inlet pipe 100 to filter out foreign substances such as metal contained in the food waste introduced therein. The food waste passing through the magnetic separator 140 is introduced into the treatment tank 200 through the inlet valve 120 .

While the food waste is introduced, the inlet valve 120 is in an open state. In the process in which the food waste is pulverized in the treatment tank 200 and heated and dried in a reduced pressure state, the inlet valve 120 is closed.

The food waste introduced into the treatment tank 200 is pulverized, stirred, or dried. Grinding, stirring, or drying may be processed in one treatment tank 200 .

The food waste introduced into the treatment tank 200 is pulverized by the pulverizer 220 . The crusher 220 is preferably located at the center of the bottom surface of the treatment tank 200 . The bottom surface of the treatment tank 200 is preferably formed with a central portion higher than the edge. In the case of separating the leaching liquid from the food waste, this is to allow the eliminative liquid to naturally flow to the edge. A desorbent outlet 240 is formed at the edge of the bottom surface of the treatment tank 200 , that is, at one lower side of the treatment tank 200 .

The grinder 220 may pulverize food waste while rotating at a high speed, but exhibits a function of stirring the food waste when rotating at a low speed. Therefore, food waste can be pulverized or stirred by adjusting the rotation speed of the grinder 220 according to the form of the prepared single feed.

The blade of the grinder 220 is preferably formed symmetrically with respect to the center of the grinder 220, and a pair of blades having different angles are positioned up and down, but the thickness of the blade may be different to be positioned. is of course Needless to say, various types of blades may be provided to increase the effect of grinding according to the rotation of the food waste, and further, to actively mix the food waste when it is stirred.

A desorbent outlet 240 is formed at a lower portion of the treatment tank 200 . The eliminator outlet 240 communicates with the eliminator discharge pipe 300 . A discharge valve 320 is located in the eliminator discharge pipe 300 , and in a state in which the discharge valve 320 is opened, the eliminant contained in the food waste is discharged to the eliminant discharge pipe 300 through the eliminant discharge port 240 .

A perforated plate 250 may be positioned on the eliminator outlet 240 . A plurality of holes formed in the perforated plate 240 pass through the leaching liquid contained in the food waste, and block the flow of the solid material in the food waste to the eliminative liquid discharge pipe 300 . The perforated plate 240 needs to be positioned when the discharge valve 320 is opened. However, when the discharge valve 320 is closed, the perforated plate 240 may be optional. Therefore, it is preferable that the perforated plate 240 is mounted and detachably mounted on the removal port 240 .

Food waste contains liquid desorbent. This talisman contains a lot of salt and various important nutrients. In the case of discharging this talismant to the outside through the eliminator discharge pipe 300, it is intended to lower the level of salt in the form of simple feed of food waste, but at the same time, many nutrients contained in the eliminator are also discharged together.

Prior to the method of converting food waste into single feed as feed for Dongae et al., food waste was dehydrated in order to lower salinity in the process of converting food waste into single feed, and then, in some cases, washing water was supplied to lower the salinity, and the feed was made into single feed. Accordingly, there is a problem in that the nutrients contained in the talismant are removed.

However, as it is known that food waste can be used as a feed for dongae, etc., which is strong in high salt, there is a method of converting the talized liquid into a single feed while maintaining the nutrients contained in the talized liquid without separating it from the food waste. is being discussed

Therefore, when food waste is used as a simple feed, it is possible to choose whether to convert it to a simple feed with high salt and high nutritional value or a simple feed with a low salt and low nutritional value. That is, when the food waste is converted into a simple feed in a state in which the talismant is separated from the food waste, the food waste is converted into a simple feed with low salt and low nutritive value. When the food waste is converted into a simple feed in a state where the talismant is not separated from the food waste, the food waste is converted into a simple feed with high salt and high nutritive value.

In the present invention, whether the food waste is prepared as a high-salt and high-nutrition simple feed or a low-salt and low-nutrition simple feed is determined whether the desorbent is discharged through the desorbent outlet 240 formed in the lower portion of the treatment tank 200. can be determined according to That is, in the case where the food waste is made into a simple feed without discharging the talismant, high-salt and high nutritive value food waste becomes a simple fodder, and in the case of discharging the talismant, the opposite is the case.

A single treatment tank 200 can convert low-nutrition food waste or high-nutrition food waste into simple feed, thereby simplifying the manufacturing process of simple feed.

When the low-salt and low-nutrition food waste is converted into a simple feed, the food waste from which the leaching liquid is separated may be washed. Such washing is performed by washing by washing water supplied to the washing water supply pipe 260 mounted on the upper portion of the treatment tank 200, or steam flowing into the steam pipe 230 mounted on the inner surface of the treatment tank 200 is transferred to the steam pipe ( As it flows out through the steam hole (not shown) formed in the 230 , and flows into the treatment tank 200 , it is of course possible to wash the food waste by steam. It is preferable that such a steam hole (not shown) can be opened and closed.

As food waste becomes a simple feed, it may be classified into a wet simple feed or a dry simple feed. In the case of not only livestock such as pigs but also dongae, etc., depending on the growth, there are times when wet-wet feed is appropriate during certain growing seasons, and sometimes dry-wet feed is appropriate during other growing seasons. That is, it is necessary to supply the simple feed in a wet or dry manner depending on the growth period.

In the present invention, one treatment tank 200 may be prepared as a wet feed, or it may be prepared as a dry feed.

In manufacturing wet united feed, wet united feed is prepared as food waste is pulverized and stirred in the treatment tank 200, and high nutritive food waste is pulverized and stirred as it is to produce wet united feed, low nutritive food The waste is produced as a wet-dried feed while discharging the desorbed liquid while the washing water is supplied through the washing water supply pipe 260 mounted on the upper portion of the treatment tank 200 to minimize salt.

In the production of dry simple feed, after the food waste is pulverized and stirred in the treatment tank 200 , steam flows into the steam pipe 230 mounted on the inner surface of the treatment tank 200 and the treatment tank 200 . As heat is supplied to the inside of the tub, the food waste located inside the treatment tank 200 is dried. These steam pipes 230 are mounted on the inner surface of the treatment tank 200 at regular intervals up and down. High nutritive value food waste is pulverized and stirred as it is, and then dried to produce dry simple feed, and low nutritive food waste is dried after discharging the desorbent to produce dry simple feed.

When the food waste is dried, heat may be supplied to the inside of the treatment tank 200 in a decompressed state to be dried. Even at 40°C under reduced pressure, moisture contained in food waste can be removed. That is, an experiment was conducted to demonstrate that moisture contained in food waste evaporates even at 40° C. in a reduced pressure state and is sucked into the pressure reducing pump 400 connected to the treatment tank 200, so that moisture contained in the food waste can be removed. was known through

In a state in which the inlet valve 120 and the outlet valve 320 are closed, the pressure reducing pump 400 is operated to depressurize the inside of the treatment tank 200 . When the food waste is dried at a low temperature under reduced pressure, the destruction of nutrients contained in the food waste is minimized due to the low temperature preferentially. Second, there is no need to raise the temperature to the boiling point of water under atmospheric pressure, thereby saving energy. Furthermore, the generation of odors generated as the food waste is dried is minimized. As it is dried at a low temperature, the movement of odor-causing substances contained in food waste is minimized, and as the movement of odor-causing substances is minimized, the amount of odor-causing substances discharged to the outside together with moisture is minimized, thereby minimizing the occurrence of odor. have.

Thereafter, as the washing water supplied through the washing water supply pipe 260 is supplied into the treatment tank 200 , the degree of salinity of the food waste may be reduced. While the washing water is supplied into the treatment tank 200 , the discharge valve 300 may be opened at the same time. At first, the leaching liquid is discharged to the eliminator discharge pipe 300 , but after that, water washing the food waste is discharged to the eliminant discharge pipe 300 .

In a state in which a certain amount of moisture is contained in the food waste, the food waste is pulverized or agitated by the grinder 220 to produce a wet sweetened feed.
