In the present invention, the method for manufacturing dry food for companion animals using the nano-technology and protein binder includes the step of nano-izing the raw material containing the raw meat containing 90% or more of the protein binder after adding the raw material.

At this time, the protein binder is 25 to 35% by weight of soy protein isolate, 15 to 25% by weight of egg protein powder, 25 to 25% by weight of alginate, Calcium phosphate 3-7% by weight, mixed phosphate 3-7% by weight potato starch 8-12% by weight, guar gum 3-7% by weight, transglutaminase 3-7% by weight, more preferably separated Soybean protein powder 30% by weight, egg protein powder 2% by weight 0%, alginate 20% by weight, 5 wt% of calcium phosphate, 5 wt% of mixed phosphate, 10 wt% of potato starch, 5 wt% of guar gum, and 5 wt% of transglutaminase.

Nanotechnology can be carried out in an impeller-structured dispersion emulsifier that can continuously inject minced raw meat with 30 to 60% mineral water. More preferably, by passing through a nano-emulsification grinder equipped with an impeller structure equipped with a cooling and heating system capable of circulating cold and hot water to the outside, the nano-sized raw material particles are pulverized to a size of ^{10 -2} to 10 ^{-3 μm.} It may be a method of manufacturing dry food for companion animals.

Most preferably, it can be carried out in a dispersion emulsifier having a rotor-rotor type impeller structure equipped with a cooling and heating system that can prevent deterioration of raw meat due to an excessive increase in the temperature of the raw meat during the nano-pulverization process.

At this time, if raw meat is pulverized into nano particles, it is possible to increase the palatability according to the enhancement of rich flavor, increase the digestibility of pepsin, reduce the amount of defecation and the smell of stool, and prevent allergies by reducing the protein molecular weight.

At this time, the nano-izing step of step (S1) is passed through a nano-emulsification grinder equipped with a rotor-rotor type impeller structure equipped with a cooling system, and the nano-ization of raw material particles is 10 ^-2 to 10 ^-3 ㎛ size Companion animal dry food It may be a feed manufacturing method.

The nanoized mixed raw material is extruded in an extruder, then cooled, cut, dried, and packaged.

In addition, step (S1) provides a method for manufacturing dry food for companion animals by adding 1 to 10% by weight of a protein binder to a raw material containing 90% or more of raw meat.

In the protein binder composition, calcium phosphate and metaphosphate, polyphosphate, pyrophosphate, etc. are mixed as the phosphate as the phosphate, which is used for the purpose of increasing the water holding capacity of the protein and increasing the binding property.

As emulsifying aids, soy protein and egg protein improve the emulsification power of the product and are used as an alternative protein when protein is insufficient. , Egg yolk powder contains protein and lecithin, so it is used as an effective emulsifier.

Alginates and gums act as thickening and tissue-strengthening agents, which increase their ability to retain water 20-30 times, and fix the meat gel to improve the tissue so that it can be sliced neatly. In addition to the function of providing viscosity and gelling products, gum can withstand high temperatures during commercial sterilization and also withstand freezing and mechanical processing.

In addition, CMC (carboxy methyl cellulose:) is used as a carbohydrate. CMC is carboxymethylated of more than 40% of hydroxyl groups in cellulose, which dissolves well in cold water and becomes a stable colloidal solution with high viscosity. Such CMC is used as a thickener or emulsion stabilizer to increase viscosity, absorbs moisture without being absorbed in the intestine and plays an important role in molding, but should be used in less than 2% of the total feed.

Potato starch is used for starch, and starch absorbs water during gelatinization to help molding and is used for the purpose of increasing the volume.

Calcium oxide uses eggshell calcium, and when dissolved in water, it dissolves the protein on the surface of the meat and creates conditions for phosphate and protein to adhere well.

Transglutaminase plays an important role in the protein binding technology of real meat of the present invention. It is an enzyme that promotes cross-linking polymerization between protein molecules, and cross-linking between glutamine and lysine residues of protein molecules. It is an enzyme that promotes binding and polymerization.

After creating a mixture of the size, it may perform a function of transferring it to the extrusion unit 130 .

Here, the bottled water supplies 30 to 60% of the weight of the raw meat in addition to the moisture on the raw meat on the nanoemulsifier 120 , thereby preventing deterioration of the raw meat.

The extrusion unit 130 is heated to a preset temperature range (90 to 150 ° C.) while re-mixing with respect to the mixture provided by the nano-emulsification unit 120, and at the same time as a cold/hot supply stage composed of a Peltier element module formed along the outer periphery. By adjusting the internal temperature under the control of the controller, it is possible not only to perform the cooking process in a stable temperature range, but also to perform a function in which the binder in the mixture and the ground meat are primarily mutually bound.

The cooling unit 140 performs cooling in a preset cooling temperature range (15 to 35° C.) for the pulverized material that has passed through the extrusion unit 130, and at the same time, along the outer periphery of the control unit for the cold and hot supply stage composed of the Peltier element module According to the control, not only can the stable cold air be preserved in the temperature range (5 to 10° C.) differentiated from the internal temperature, but also it is possible to provide a function of circulating the internal temperature of the cooling unit 140 to the outside.

In addition, the cooling unit 140 may perform a secondary binding function through solidification of the mixture by strengthening the binding function of the primary binding agent and the ground meat on the extrusion unit 130 .

The cutting unit 150 performs molding through cutting into a particle size of a preset particle size for the completely binding and solidified mixture through the cooling unit 140, preferably 3 mm to 10 mm, and then the drying unit 160 The function to transfer to
