The tank 110 has a space formed therein so that the by-products for removing water are temporarily stored therein, the inlet 111 through which the by-products are input, and the discharge part 112 through which the dried by-products from which moisture is removed are discharged. It is composed of a structure having a).

Tank 110 is installed spaced apart from the ground at a predetermined interval, it may be configured to be supported by the support (160).

In addition, the heat generating unit 120 includes a central shaft 121 rotatably installed in the horizontal direction of the tank 110, a connecting member 122 fixed to both ends of the central shaft 121, and a connecting member 122. It is configured to include a plurality of steam pipes 123 are installed at intervals of a predetermined angle at the edge of the.

The central shaft 121 is installed in the transverse direction in the center of the tank 110, rotates, made of a pipe structure so that the high temperature steam is injected therein, and is configured to rotate by the rotating means 130.

The connection member 122 is configured to communicate with the inside of the central shaft 121 in a hollow state.

The plurality of steam pipes 123 are fixed to the connection member 122 and are configured to communicate with the inside of the connection member 122.

Therefore, when hot steam is injected into the central shaft 121 through the inlet 140, it is supplied to the plurality of steam pipes 123 through the connecting member 122, and the central shaft, the connecting member, and the steam pipe. It is configured to generate heat.

That is, the steam injected into the central shaft 121 and the inside of the steam pipe 123 is deprived of heat while vaporizing moisture contained in the by-product and converted into condensed water to be discharged to the outside through the outlet 150. .

In addition, by the steam injected into the steam pipe 123 to rotate with the central axis 121 can be delivered to most of the by-products introduced into the tank 110.

The by-product heated in the heater 100 having the above configuration should be heated to a temperature at which moisture can evaporate, that is, at a high temperature of 100 ° C. or higher, which is the boiling point of water, and preferably heated to 110 ° C. to 140 ° C., more preferably. It is heated to about 120 ℃. Because, if the temperature to be heated is too low, the processing process in the heater 100 takes a long time, and also the moisture evaporation effect is reduced, it is impossible to completely remove the moisture contained in the by-products. If the heating temperature is too high, too much energy is consumed, and the produced product may be discolored, resulting in poor commerciality.

On the other hand, the by-product injected into the heater 100 is heated by the high temperature steam is evaporated moisture contained therein. As such, the by-product discharged in the evaporated state of the heater 100 is supplied to the separator 200 to be filtered by solids and oil.

The separator 200 is a first separator 210 for filtering relatively fine solids and oil from the solids and oil discharged from the heater 100, and again in the fine solids and oil filtered by the first separator (210) It comprises a second separator 220 for separating only the oil.

The first separator 210 has a screen structure in the form of a net so that solids and oil can be separated according to size.

On the other hand, a relatively fine solids and oil is filtered by the first separator 210, a relatively large solids are transported without filtering is provided with a storage unit 300 is temporarily stored.

That is, while solids and oils of various sizes discharged from the heater 100 pass through the first separator 210 of the screen structure, solids that are not large enough to pass through the screen are not filtered out of the first separator 210 as they are. The solid and oil that are fine enough to be transferred to the storage unit 300 and pass through the screen are filtered through the screen of the first separator 210 and filtered downward.

In addition, the fine solids and oil filtered down to the lower portion of the first separator 210 are separated into the solids and oil again in the second separator 220. To this end, the second separator 220 is configured to operate in a centrifugal separation method, and the fine solids and oil filtered by the first separator 210 are separated from each other by the centrifugal separation method in the second separator 220.

The storage unit 300 is a device in which relatively large solids not filtered out of the first separator 210 and relatively fine solids separated from the first separator 210 are temporarily collected and stored together. And, the solids are temporarily stored in the storage unit 300, because a certain amount of solids must be collected together and transferred to the extractor 400 to be introduced into the pressing process.

Thus, a certain amount of solids collected in the storage unit 300 is transferred to the extractor 400 to undergo a compression process, and the oil contained in the solid content is extracted through this compression process.

On the other hand, the solids separated from the first separator 210 and the second separator 220 are transferred directly to the extractor 400 without being transferred to the storage unit 300, and then the oil contained in the solids is extracted through a compression process. It can also be applied to the configuration.

The solids extracted from the oil through the pressing process in the extractor 400 are then pulverized into a powder form in the grinder 500 to complete the protein feed.

The feed production apparatus according to the present invention preferably further includes a mill cooler for cooling the solids using the sucked outside air before the solids discharged from the extractor 400 into the grinder 500. That is, the solids extracted from the oil during the compression process in the extractor 400 are transferred to the mill cooler, cooled by external air, and then transferred to the grinder 500 to be pulverized into a powder form.

A method of preparing a feed according to the present invention will be described with reference to FIG. 5.

First, the by-products are put in the heater 100 and heated by heat generated by the high temperature steam supplied to the heater 100 to evaporate the water contained in the by-products with water vapor. It is desirable to heat the added by-products so that most of the moisture contained in the by-products can be removed.

In addition, the water removed from the by-product is evaporated in the form of water vapor, and the vaporized water vapor is discharged to the outside by a fan that sucks the internal air to the outside, it is configured to be condensed by water at room temperature and discharged into the waste water desirable.

The by-product heated by the steam of high temperature is removed by the heat generating unit 120 of the heater 100, and then discharged as solids and oil of various sizes are transferred to the separator 200. And from the solids and oil of various sizes supplied to the first separator 210 of the separator 200, to filter out the relatively fine solids and oil, only a relatively large solids remain (S16).

As such, the first separator 210 for separating solids and oil according to size is made through a screen of a mesh structure. That is, solids and oils of various sizes that pass through the screen that are too large to pass through the screen remain unfiltered, and the fines and oil that are fine enough to pass through the screen are filtered down through the screen. do.

Thereafter, only the oil is separated from the fine solids and oil filtered through the screen again. For example, the oil is separated from the fine solids in the second separator 220 of the centrifugal separation method.

Then, the large solids not filtered through the screen and the fine solids caught from the screen and separated from the oil again are collected in the storage 300.

As such, solids of various sizes temporarily stored in the storage unit 300, that is, relatively large solids not filtered out by the screen, and fine solids filtered out of the screen and separated from oil again are pressed together in the extractor to be contained in the solids. Extract the oil (S22)

The solids extracted from the oil through the pressing process are cooled by the inhaled outside air (S24), and then pulverized into a powder form (S26) to complete the feed.

On the other hand, the solids separated from the first separator 210 and the second separator 220 may be applied to the configuration to move the extractor 400 immediately without going through the storage unit 300 to extract the oil. .

Only about 2% of the water remains in the feed produced through this process, and the remaining water contained in the by-product is evaporated and removed by steam during heating by steam. And because it is heated by high temperature steam, the by-product itself has a unique smell disappears, all the bacteria and parasitic parasitic by-products are sterilized.
