DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic diagram showing one embodiment of the present invention.

As shown in FIG. 1, the present invention uses residual food (including waste edible oil) discarded from restaurants, schools, hotels, general hospitals, food processing facilities, dismantling and processing facilities for livestock, fish and the like. Collect and use for each occurrence location. The residual rice is processed in a mixing / kneading step (which may include a compression step), an extrusion step, a cutting step, and an emptying step to become a product. As will be described later, these steps may be performed alone or in a plurality of steps by one apparatus.

[0010] The generated leftovers are temporarily stored or transferred to a mixing / kneading step in a collected state. mixture/
Before the kneading step, it is also possible to remove water adhering to the residual rice by draining as a pretreatment or by centrifugation. At this time, the moisture contained in the residual rice is squeezed out by squeezing, and the shape stability of the processed product from the extrusion process in the subsequent process may be enhanced. It is also possible to use the kneader as a mixing / kneading device in the mixing / kneading step.

In the extruding step, the mixture is uniformly mixed in the mixing and kneading step, and if necessary, is extruded into a rod shape in a predetermined shape by a press in a state where the amount of water contained is adjusted by pressing.

Ectruders are more preferably used because they also serve as mixing / kneading and extrusion steps. The remaining food in the extruder was mixed, kneaded, and water was squeezed out during the extrusion process.At the same time, the temperature rose, and a considerable amount of the remaining water contained in the waste was discharged from the vent as steam and pushed out into a rod shape. Shape stability of the processed material can be improved.

[0013] The water content contained in the garbage is adjusted by squeezing or by changing the pressure and time in an extruder. When a kneader is used in the mixing / kneading process, the extruder is not used by pressing before and after the mixing / kneading process, adjusting the amount of water contained in the residual rice, and then sending it to a press machine which is an extrusion process. Has the same effect. In this case, since the temperature does not rise as in the case of the extruder, it is not possible to kill various germs contained in the leftovers. The squeezed water is separately treated.

In particular, when an extruder is used,
Since a large shear force acts on the leftovers, foreign substances such as toothpicks contained in the leftovers are crushed. Feeding the products thus obtained to livestock, poultry or pets as feed or feed does not damage them.

The remaining food from the extrusion step is extruded in a shape suitable for the intended use by changing the shape of the die of the extruder.

The extruded residue is cut into pellets by a cutter into a predetermined length. When the cutter is small, a reciprocating cutter can be used, and when the scale is large, a rotary cutter is used.

The pellets obtained in the cutting step are fried in deteriorated cooking oil in the fry step. Deteriorated hot water may be used after simple filtration. The conditions for fried foods such as normal tempura can be applied to the conditions for fried food. By frying, some of the degraded cooking oil migrates into the pellets. Degraded edible oil can be reduced, and moisture remaining in the pellets can be further reduced. The amount of remaining water can be arbitrarily adjusted by adjusting the time of the temperature at which the liquid is fried, and can be suitable for storage.

The remaining rice obtained from the frying step can be used as it is or as a part of feed or bait. Furthermore, spices contained in the leftovers are broken down during frying. Spices have different decomposition temperatures depending on their types. Therefore, the type of the remaining spices can be changed by changing the fry conditions.

For example, pepper, tabasco, pepper, etc.
At a temperature of 80 ° C or higher, wasabi, garlic, ginger, etc. are at a temperature of 150 ° C or higher, and green onions, leek, onions, etc. are 12
It can be reduced by frying at temperatures above 0 ° C. By changing the fry conditions, appropriate feed and feed can be obtained according to the types of poultry, fish, and pets.

By fried, the water in the pellets evaporates, and the pellets become rich in voids by foaming. Furthermore, since it contains oil, it has water repellency and can float on the water surface for a long time.

When used as fish feed, the position in the water where the feed is eaten differs depending on the habit of the fish. From the management point of view, foods floating on the water surface are important for maintaining good water quality. The feed obtained by the present invention is particularly excellent as a fish feed.

[0022]

The present invention has the following effects because it is processed in a mixing / kneading step (which may include a pressing step), an extruding step, a cutting step, and an emptying step. (1) By going through the kneading, extrusion step and emptying step, it is possible to adjust the water content of the leftovers and to change the form into a form suitable for storage. (2) By using an extruder in the mixing / imitation process, foreign substances such as toothpicks contained in the remaining food can be evenly mixed by grinding, and when used as feed for livestock, livestock Do not harm. (3) By changing the fry temperature, the type and amount of spices contained in the garbage can be changed, and foods according to the types of livestock, poultry, and pets can be provided. (4) Since it floats on the water surface for a long time, it is particularly suitable as a feed for fish.
