Description

A system which makes provenders for food wastes}

The present invention relates to a food waste feeding system, and in particular, the food waste introduced into the plastic bag is collected and decompressed, compressed and dehydrated, and then injected into the fertilizer, mixed with sterilized and crushed while drying in the order of hot and cold air, and then pulverized. The present invention relates to a food waste feed system that minimizes the destruction of nutrients in food by the molding process and can be used as a feed for producing high quality animal feed.

In general, leftover foods discharged from homes, restaurants, and catering establishments cause pollution due to leachate during landfill, and nowadays, food waste is recycled into animal feed.

Food waste recycling technology can be classified into natural drying method, dehydration reduction method, hot air drying method, anaerobic fermentation method and liquid feed method. In particular, the dehydration reduction method and the hot air drying method are treated as single equipment.

However, the natural drying method is a method of mixing the leftover food with moisture control agent (sawdust, etc.) and drying it naturally to use as compost. This method takes a lot of processing time and causes further environmental pollution due to the propagation of odor and various germs. .

Hot air drying method is to dry food with a lot of moisture by high temperature hot air, which destroys the nutrients of food and composting due to carbonization, but it is hard to use as feed.

Anaerobic fermentation is a method of composting food and fermentation agents or microorganisms left in a large-capacity tank. Secondary pollution due to odors and curing of microorganisms or fermenters require advanced techniques and are difficult to operate without experts.

The liquid feed method is a method of putting food left in a large container to boil at a high temperature to make it difficult to sort out foreign substances contained in the food, and in particular, if it is not consumed immediately due to the contamination of various harmful microorganisms in summer, there is a risk of deterioration.

In addition, such a conventional food waste recycling method has a disadvantage in that it is not effective because it does not remove the salt in common or the devices and processes for removing the salt is too difficult and expensive, and the food waste itself is used as feed for animals. There is a drawback of too much nutrient deficiency.

The present invention was devised to solve the disadvantages of the prior art, and its purpose is to separate and collect food waste flowing into the plastic bag, and then squeeze it, compress and dehydrate it, and then mix it by adding a fertilizer and drying in order of hot and cold air. The present invention provides a food waste feed system that produces high quality animal feed by minimizing nutrient destruction by sterilization, pulverization and pellet molding.

In addition, these processes can contribute to income growth by supplying livestock farms at low prices by recycling them with high quality animal feed.

1 is an overall process of the food waste feed system according to the invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a general process of the food waste feed system according to the present invention.

Food waste is introduced through a separately provided food waste collection container or transported in a state in which it is put in a separate plastic bag, so the first bagging device 10 is necessary.

The wave breaking device 10 has a structure in which a transfer screw 12 is installed at a lower portion of the input hopper 11, and a plurality of wave rods 13 are formed at one side in a direction in which the transfer screw 12 rotates. In addition, a discharge port is installed at one side of the input hopper 11 so that food waste is transported, and a plastic bag separation device 14 for automatically separating the broken plastic bag is installed at one upper part.

The food waste put into the apparatus is broken by the piercing blade 13 and transported by the conveying screw 12, and the crushed plastic bag is separated and discharged by the plastic bag separating device 14. In addition, when the plastic bag is selected, an automatic plastic bag separator 14 may be used, and an operator may directly separate and separate the plastic bag.

In addition, the rear side of the shredding device 10 is provided with a shredder 20 for shredding food waste finely. And a conveyor 15 for transporting food waste is installed between the breaking device 10 and the crusher 20. At this time, the upper portion of the conveyor 15 is provided with a metal sorting device 16 using magnetic force to separate the metal contained in the food waste.

Food waste from which metal is separated while passing through the metal sorting device 16 is introduced into the crusher 20 and crushed finely.

Finely crushed food waste through the crusher 20 is introduced into the pressure dewatering device 30 through a conveyor (screw conveyor). Food waste contains a lot of water, so it must be removed to process it into feed. Therefore, dehydration is performed by the pressurized dehydration apparatus 30 and the sewage is drained to the sewage tank 31 installed at the lower portion of the pressurized dehydration apparatus 30. When pressurized dehydration, the salt contained in the food waste is dehydrated with water, so the salt concentration is lowered to some extent. The sewage collected in the sewage tank 31 is drained and purified by a separate sewage treatment device.

On the other hand, the pressurized dehydrated food waste is introduced into the mixer 40 through the conveyor. When kneading the pressurized dehydrated food waste with the mixer 40, a feed material such as rice bran is added from the feed material input device 41 installed on one side and mixed evenly. In this mixing process, the concentration of salt in food waste is diluted to a degree that is harmless even if animals eat it. Food waste, in particular, lacks nutrients for animals to eat, but as the forages are mixed, they can have enough nutrients. In addition, the forage may vary depending on the type of animal being eaten.

Mixed food waste mixed with forage is transferred to a drying apparatus 50 through a conveyor.

The drying apparatus 50 is divided into cold air drying and hot air drying sections. That is, the conveyor 15 is installed inside the cylindrical drying chamber, and the heat shielding film 53 is provided inside to form two drying chambers 51a and 51b, and one drying chamber 51a uses the cold air blower 54. In order to supply cold air by the apparatus, the other side drying chamber 51b is provided with a hot air fan 55 to dry in order of cold air and warm air. When supplying hot air and cold air from the hot air fan 55 and the cold air fan 54, a plurality of injection holes are formed to supply the air evenly, thereby increasing drying efficiency.

When it is dried by applying heat, many nutrients are destroyed, so it is dried by cold air drying and then by warm air drying. In addition, it will perform a function to sterilize various germs of mixed food waste during drying.

In addition, the dried mixed food waste is introduced into the gear mill grinder 60 through the conveyor 15.

The gear mill 60 has a splined inner tooth housing 61 therein, and a sun gear 62 rotating therein with a shaft in the center thereof, and a sun gear 62 and an inner tooth housing 61 around the gear grinder 60. It is composed of a planetary gear 63 is rotated in engagement with the spline of, the planetary gear 63 is rotated to crush the mixed food waste located between the inner tooth housing 61 and the sun gear 62.

When the mixed food waste is crushed as described above, the pellets are molded into particles of a suitable size through a pellet molding machine 70 so as to be convenient for animals to eat.

The molded feed is packaged using a packing machine 80.

As described above, the present invention separates and collects the food waste flowing into the plastic bag, compresses and dehydrates it, and compresses and dehydrates it. By minimizing the destruction of nutrients has the effect of obtaining a high quality animal feed. In addition, these processes can contribute to income growth by recycling them to quality animal feed and feeding them to livestock farms at low prices.
