Description

[Detailed description of the invention] (Industrial application field) This invention kneads the main raw materials with beef bone soup,
This relates to a dog food production method characterized by heating, granulation, and subsequent drying, and is used in the field of dog food production.

(Prior art) Traditionally, dog food has been made by kneading grain flour, meat flour, and meat and bone meal with water, heating it with steam, granulating it, and then adding flavor to it to give it an odor, or adding flavor to each grain after granulating it. The outside surface is coated with beef tallow.

(Problems to be solved by the invention) According to the conventional manufacturing method, after the dog food is granulated and dried, flavor is added to the atmosphere, so if the amount of flavor is small, the animal's palatability is poor. Since it does not penetrate to the inside, there is a risk that palatability may be impaired.

(Means for Solving the Problems) However, this invention uses beef bone soup instead of water for kneading raw material flour, etc., so not only is the drying efficiency good, but the taste is the same even inside the particles, making it possible to improve the taste of the animal. The above-mentioned conventional problems have been solved by improving palatability and evenly mixing beef tallow.

That is, in this invention, grain flour, rice bran, meat meal, and meat and bone meal are blended in a predetermined ratio, stirred, crushed, heated with steam while adding an appropriate amount of insulated beef bone soup, and then pressure-extruded and granulated. After that, the moisture content is 8%.
This dog food manufacturing method was completed by drying before and after.

The flour in the above is corn, wheat flour, etc., and the beef bone soup is made by boiling crushed beef bones and beef sinew with a large amount of water. and store it. The beef bone soup contains a large amount of beef tallow and protein, but since it is kept at a temperature of 40°C to 70°C, the beef tallow remains liquid and can be mixed uniformly with the raw materials.

(Function) According to this invention, since the beef bone soup is evenly mixed with the raw material, a dog food that is homogeneous and has an odor that stimulates the taste can be produced, and after granulation, the inside and outside are homogeneous, so it is suitable for the taste of animals. .

(Example) Next, the present invention will be described with reference to embodiments.

400Kg corn, 50Kg flour, 100Kg, bran
100Kg, meat powder, 100Kg of meat and bone powder, etc. are put into the mixer 1, thoroughly stirred to mix uniformly, and then sent to the crusher 2 to be finely pulverized.

This pulverized material is put into feeder 3 and fed.
Beef bone soup at a temperature of 40° C. to 70° C. is sprinkled on the ground material to make up about 20% of the ground material, and the grains are heated with steam while being humidified to gelatinize the grains. Next, the vaporized product is put into a granulator 4, extruded under pressure, and cut with a cutter 5 (for example, a diameter of
8mm, length about 6-10mm). In this case, the food grains have a moisture content of around 25%. The product is then placed in a dryer 6 to have a moisture content of around 8%, and then sent to a product hopper 7. The beef bone soup mentioned above is produced as follows.

Add 100 kg of beef sinew and 2,000 kg of water to 300 kg of crushed beef bones and boil for about 60 hours. The purpose of this boiling time is to ensure that the bone marrow is completely dissolved, and if the amount of water decreases, add as needed to make the final soup of 1,700 ml. The soup is then filtered to separate solids and the liquid is stored in a storage tank. In this case, the temperature is constant at around 80°C. This beef bone soup is pumped (for example, 2
Kg/cm ² ) to send the appropriate amount. The temperature of the pressure-fed soup should be around 40°C to 60°C in winter and 50°C to 70°C in summer.
The dog food produced according to the present invention has the advantage that it is homogeneous both inside and outside, is suitable for the palatability of animals, retains sufficient odor, and does not get tired even when fed for a long period of time. (Effects of the Invention) According to this invention, since the beef bone soup kept at a temperature of 40°C to 70°C is mixed, the taste and odor of the beef bone soup are evenly mixed, and the beef fat content is evenly distributed. It is highly palatable to dogs and has excellent feeding continuity.
