Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a wetsuit/gum candy for pet animals.

Breeding pet animals prevents the monotony of life and adds enrichment to life.Recently, as living standards have improved, more and more people are breeding pet animals such as dogs and cats. It has increased. At present, interest in pet animals is increasing, as it is now possible to keep dogs and cats indoors in condominiums and the like.

Dogs have a habit of chewing on things, and when indoors such as apartments, they often take out slippers and other items to hold them down with their front paws and chew on them. At this time, if you take away the slipper or do not give the dog something to chew on, such as a slipper, the dog may develop a nervous disorder or behave abnormally.

If given animal bones, dogs will happily gnaw on them and wilt, but animal bones themselves are difficult to use indoors because they can get dirty and cause a bad odor. There, the bones of animals are boiled and the meat removed and then sold as oshiyaburi. However, bones that have been boiled and the meat has been removed have a taste and odor that are far different from those of animal bones, and are suitable for feeding to pet animals indoors because they are clean and odorless.
Animals get tired of these things quickly and stop playing with them.

In view of the current situation, the present inventor conducted various studies and arrived at the present invention. The product obtained by the method for producing pet diapers and gum candies according to the present invention can be used as diapers for pet animals, or can be chewed and eaten, and can be used for dogs, etc. The object of the present invention is to provide something for pet animals to enjoy biting and playing with, and for preventing pet animals from developing neurosis.

In the present invention, a mixture of 90 to 20% by weight of bone meal and 10 to 80% by weight of milk casein, to which a desired amount of an alkaline additive and water is added, is continuously subjected to heating and pressure processing using an extruder. It is characterized by cutting the extruded material into desired lengths.

Bone meal and milk casein are both powders, and in order to make them into gum candies and diapers, they need to be molded into appropriate hardness and desired shapes. There is also a method of adding water and kneading bone meal or bone meal milk casein mixture with a sizing agent such as starch, natural gum, or kagainate sodium, then molding and drying.
Products made using the same method are brittle, and when given indoors, they contaminate the jutan, etc., and require a large amount of water for molding, making drying expensive and time-consuming, resulting in cracks and other drawbacks.

Adding appropriate amounts of alkaline additives and water facilitates the plasticization of casein, ensures complete and sufficient mixing and binding with bone powder, and at the same time imparts elasticity to the molded product and eliminates brittleness.

Bone meal includes bone meal from cows, pigs, mutton, birds, fish, etc., and any of them can be used in the present invention. However, among these, bone powder from animals such as cows and pigs is suitable, and dogs and the like jump on the wetsuit and gum candy for pet animals according to the present invention, gnaw on it, and do not let it go.

Milk casein includes acid casein such as lactic acid casein, hydrochloric acid casein, and sulfate casein, as well as rennet casein and soluble casein, and any of them can be used in the present invention. Examples of alkaline additives include bicarbonates such as sodium hydroxide, potassium hydroxide, or sodium bicarbonate, phosphates such as sodium phosphate, and carbonates. The amount of alkaline additive used may be an amount that makes part of the milk casein soluble, or may exceed an amount that makes all of the milk casein soluble. Normally, if 5% by weight of sodium bicarbonate is used with respect to milk casein, all milk casein can be solubilized. It is undesirable to use the alkaline additive in an amount that greatly exceeds the amount necessary to make milk casein soluble. In such a case, the pet wetsuit/gum candy according to the present invention will exhibit strong alkalinity, which may cause harm to the pet animal.

Note that it is difficult to make rennet casein, a type of milk casein, 100% soluble casein, so it can be produced by mixing acid casein if desired, or if 100% soluble casein is desired, acid casein etc. can be used. .

The alkaline additives may be used alone or in combination of two or more. When used, it can be dissolved or dispersed in water and mixed, or it can be added in the form of a powder.

Water is necessary to dissolve the alkaline additive and disperse it uniformly in the mixture, and it is also necessary to be absorbed by the milk casein and to plasticize and solidify the entire mixture by heating and pressurizing. It is. If the amount of water is too small, the alkaline additive will not be sufficiently dispersed, so that the solubilization of milk casein will not proceed uniformly, and the mixture will not be sufficiently plasticized and solidified, resulting in a fragile product. On the other hand, if there is too much water, the mixture tends to harden and cause caking, making it unsuitable for continuous whole mold processing in an extruder without falling smoothly from the hopper of the extruder. In addition, the pet wetsuit/gum candy obtained is soft and fragile, and in some cases, it takes a long time to dry afterwards.

Note that the pet wetsuit/gum candy according to the present invention uses bone meal as one of its components and limits the amounts of bone meal and milk casein, so the problem of stickiness due to soluble milk casein does not occur. The heating and pressurizing process may be performed intermittently or continuously, but continuous processing is easy and simple. For continuous processing, an extruder widely used in rubber processing and synthetic resin processing can be appropriately used.

The extruder used in the present invention rotates the screw in the cylinder to send the mixture input from the hopper forward, and the pitch of the screw becomes smaller as it goes forward, so that the mixture is pressurized at the same time as extrusion. It's summery. At the same time as it is pressurized, it is extruded while being kneaded by the mass in the cylinder. Attach two heatable caps to the front of the screw. The first nozzle has a narrow outlet for sufficient pressure and kneading, and the second, most advanced nozzle is interchangeable to mold the product into the desired shape.

Since the present invention is configured as described above, when you give the pet diaper/gum candy of the present invention to a dog etc., the dog will happily bite it.
Since the dog eats and plays with the dog, it does not chew slippers or the like, and the dog does not suffer from neurosis, making it easy to raise the dog. Furthermore, since the baby diaper and gum candy according to the present invention does not cause the problem of stickiness, there is no risk of staining the room even if it is given to a dog or the like indoors. Furthermore, since the manufacturing method according to the present invention uses an extruder to continuously manufacture, the wet towel and gum candy according to the present invention can be easily and easily manufactured.

As described above, the diaper and gum candy and the method for producing the same according to the present invention have many advantages.

Next, the present invention will be explained in more detail with reference to Examples.

Example 1 Lactic acid casein (20
~40 mesh mixture) 60 kg of milk casein, 10 kg of rennet casein, and 30 kg of beef bone meal (a mixture of 20 mesh to 120 mesh) were placed in a mixer at 240 revolutions per minute, and while rotating, sodium hydroxide 1.0
Gradually add a solution of Kg dissolved in 14Kg of water, mix and absorb evenly, and then powder sodium bicarbonate
Mix 1.4Kg. The total mixing time is completed in 3 to 4 minutes. If the mixture is mixed for a long time, it will generate heat and solidify, which will interfere with the next process. The mixture is divided into paper bags, taken out, and extruded using the next extruder. The extruder is a device with a rotating screw in a cylinder with an inner diameter of 87.6 mm and two electric heating caps with automatic temperature controllers of 600W and 200W attached to the tip of the screw, and the rotation speed of the screw of the extruder is 20 revolutions per minute. Set the temperature of the two caps at the tip to 95
The state-of-the-art molding nozzle has a hole diameter of 10 mm at temperatures ranging from 100℃ to 100℃.
The diameter of ^the extruded product is 15 mm to 18 mm.
Cut the extruded material into lengths of 10 to 13 cm.

In Example 1 above, when the mixture of acid casein and bone meal absorbs sodium hydroxide, the surface of the casein is solubilized by the alkaline solution and becomes paste-like, producing bean-like lumps, which are kneaded in the extruder. So there is no problem. The color of the molded product is almost constant, slightly yellow or yellowish white when casein is used alone.
Changes depending on the color of bone meal. The diameter of the pore of the molding nozzle at the tip and the diameter of the extruded molded product increase as the casein content increases, and decrease as the amount of water added increases.

Example 2 30Kg of milk casein hydrochloride and 70Kg of beef bone meal
Mix 1.5Kg of sodium bicarbonate in a mixer and then add a solution of 0.3Kg of 85% phosphoric acid in 12Kg of water to the mixture of acid casein, bone meal and sodium bicarbonate.
The mixture was gradually added while rotating the mixer, and the mixture was uniformly absorbed using the same extruder as in Example 1, at a nozzle temperature of 130° to 150°C, an extrusion pressure of approximately 6 kg/cm ^{2 ,} and a molding nozzle with a hole diameter of 20 mm at the extrusion tip. Extrude continuously. The diameter of the extruded material is 22 mm to 25 mm. The extruded product is cut into lengths of 10 to 13 cm and used as oshiyaburi and gum candy.
