Description

[Detailed description of the invention]

The present invention relates to a method for grinding beef bones into a smooth paste. Traditionally, edible animal bones such as beef, pig, and chicken bones are boiled to extract fat and gelatin, or used directly to make soup, or ground to form a paste and used as raw material for ham, hamburgers, etc. It has been reported to be used as For example, a method for making animal bones into a paste includes a first step of crushing the animal bones with a crusher into fine pieces, and a second step of grinding the obtained fine pieces while adding water; The first step is to cut the animal bone into flakes using a rotary cutting machine with a specific cutting edge angle, the second step is to shred the obtained flakes using a shredding machine, and the resulting fine pieces are further cut into thin pieces using a grooved roller. A method for obtaining fine viscous bone fragments is known, which comprises a third step of crushing the bone fragments into the shape of fine viscous bone fragments. However, when animal bones are ground using the above-mentioned conventional method, it is difficult to grind them into smooth fine particles (paste-like), especially in the case of hard bones such as cow bones. The present inventors have conducted various studies on a method of utilizing bovine bone, which contains large amounts of nutritional components such as bone protein and calcium, in the form of smooth fine particles, and have developed a chopper with a specific outlet hole diameter and a sliding grinder. The present invention was completed by discovering that even hard bones such as beef bones can be made into a smooth paste by using the above in combination. That is, the present invention includes a first step in which the beef bone is passed through a cutter having an outlet hole diameter of 5 to 10 mm, a second step in which the beef bone is passed through a cutter having an outlet hole diameter in the range of 1 to 5 mm, and then the beef bone obtained in the second step. The gist of the present invention is a method for producing a beef bone paste, which comprises the following steps: a third step of turning the chopped beef bone pieces into a paste using a sliding grinder. As the chopper used in the present invention, an apparatus as shown in FIG. 1 can be mentioned. That is, FIG. 1 is a partial cross-sectional view of the hopper used in the present invention, showing the hopper 5 for introducing the beef bones, and the helix 4 for transporting the introduced beef bones toward the outlet while rotating with the power given from the pulley 6. , consisting of a knife 3 that rotates together with a helix 4 and a plate plate 2 having an exit hole 1, and the beef bone transferred and compressed by the rotating helix 4 is crushed into small pieces by sliding between the knife 3 and the plate plate 2. In the chopper of the present invention, the diameter of the outlet hole 1 is 5 to 10 mm in the first step, and the chopper in the second step is used in two stages, with the diameter of the outlet hole 1 being 1 to 5 mm. It is necessary. In this case, if a chopper with an exit hole diameter of 1 to 5 mm is used in one stage, not only will the beef bones not be cut into pieces smoothly, but the resulting beef bone paste will not be smooth. In the method for producing beef bone paste of the present invention, a cutter having a specific outlet hole diameter as described above is used in two steps, and then it is further ground by a sliding grinder. An example is a grinder as shown in the figure. That is, FIG. 2 is a sectional view of a device showing an example of a sliding grinder used in the present invention, in which a grindstone 101 fixed to the device body and a separately installed motor (not shown) are connected to a pulley 105. The given rotation is mainly composed of a sliding grindstone 102 that rotates with a vertical axis 103. The beef bone fragments obtained in the first and second steps of the present invention are transferred from the hopper 106 to the grinding wheel 1 which rotates and slides.
01 and 102 and is discharged to the outside from the outlet 107. At this time, the vertical shaft 103 of the sliding grinder is pushed up by a suitable push-up means 104 applied to a part of the shaft from the outside by a spring or hydraulic pressure, and a suitable grinding force is applied between the grinding wheels 101 and 102. It is necessary that pressure be applied. In addition, the sliding whetstone 101
Examples of the grinding wheel 102 include a grindstone formed of caborundum, alundum, etc. using a thermosetting resin such as an epoxy resin as a binder. As described above, the present invention uses a chopper having a specific pore size in the first and second steps, and further in the third step.
A smooth beef bone paste can be produced by using a sliding grinder as a process. When operating the above-mentioned first, second, or third step of the present invention, by appropriately adding thin ice, ice water, or water onto the beef bone pieces, the chopper or sliding grinder can be rotated smoothly. can. Next, the present invention will be explained with reference to Examples and Comparative Examples. Example 1 Raw material beef bones extracted at a slaughterhouse were heated to -20℃
The beef bones were cooled to a fine powder using a chopper with an outlet hole diameter of 6.5 mm, which was further cut into fine pieces using a chopper with an outlet hole diameter of 2.5 mm.
MKZB15-40 (manufactured by Masuko Sangyo Co., Ltd.) was passed to obtain a beef bone paste. The obtained beef bone paste was a very smooth pink paste with almost no foreign substances. Examples 2 to 5 and Comparative Examples 1 to 3 Beef bone paste was produced in the same manner as in Example 1 except for the conditions shown in Table 1. The results are also shown in Table 1.
