DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for cutting or cleaving bulk fats and oils (hereinafter, referred to as frozen bulk fats and fats) such as frozen butter and margarine into frozen pieces. The bulk fats and oils are efficiently cut or cleaved into small pieces as they are.

[0002]

2. Description of the Related Art Some fats and oils foods such as butter and margarine are packaged in a lump of about 10 to 30 kg, further frozen and stored. The frozen bulk fats and oils are usually frozen at -20 ° C. or lower, and therefore have a high antioxidant effect during storage, and are effective means for maintaining quality. In particular, in the case of butter, the amount of butter produced in summer becomes the largest in summer, while the amount of consumption tends to increase in winter. It has been done to save. The lump butter frozen and preserved in this way is used as fat for kneading dough during confectionery and baking, or as raw material fat for processed food (hereinafter referred to as fat for business use),
Also, as tabletop fats and oils for cooking at home, for example, 5
It has been renovated to a weight of about 500 g.

[0003] In the case of using the above-mentioned fats and oils such as frozen bulk butter as commercial fats or oils, or remodeling them as household table fats or cooking fats and oils, they cannot be used directly in a frozen state. The frozen bulk oils and fats are put in a refrigerator, and the temperature is raised to about 5 ° C over about 30 days before use. It takes a long time to raise the temperature, because the thermal conductivity of the fats and oils is so low that the temperature does not easily rise to the center, and the frozen bulk fats and oils contain moisture (about 16% for butter). Phase change of water (change from solid phase to liquid phase)
It takes a long time, and if the temperature of the heating chamber is set to a high temperature, the surface melts and the quality deteriorates before the center heats up. It is listed as.

[0004] The work of raising the temperature of the frozen bulk oils and fats, which takes a long time, not only causes a decrease in work efficiency and productivity or an increase in energy cost, but also causes problems such as deterioration of the oils and fats and contamination by microorganisms. It also includes the danger of causing. For this reason, the present applicant has previously proposed a pulverizing and heating method and apparatus which directly pulverizes frozen bulk butter and does not require a heating period (Japanese Patent Application Laid-Open No. 7-23710). The method involves scraping the surface of frozen bulk butter at about -20 ° C with a cutting blade, and using frictional heat generated during scraping, raising the temperature at the same time as pulverization to form a particulate butter in the range of -7 ° C to + 3 ° C. Is generated.

In addition to the above-mentioned apparatus for crushing and heating frozen butter, a rotary cutting machine, a lifting / lowering cutting machine, a push-cutting cutting machine and the like are conventionally used as a general food cutting device. There are rotary cutters known as slicers and band saws.These cutters rotate circular round blades, saw blades, or band saw blades to produce fish, animal meat, vegetables, cereals, fruits, and more. For cutting or chopping breads, breads, processed foods and the like. An elevating type cutting machine includes a so-called guillotine type cutter, which raises and lowers a cutting blade for cutting and cuts or shreds food such as fish, bread and vegetables. Furthermore, the push-cut type cutting machine arranges a plurality of cutting blades at regular intervals or in a lattice, and presses foods such as bread against the cutting blades to cut them.

[0006]

SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Application Laid-Open No. Hei 7-23710.
The method of crushing and heating the frozen bulk butter described in Japanese Patent Application Publication No. 2000-214, is a method in which a frozen bulk butter is cut at a relatively high speed by a crushing device in which a cutting blade is arranged on the surface of a cylindrical carrier rotating in a circumferential direction. Since the temperature is increased while grinding, the frictional heat generated by the cutting blade rotating at a high speed is unnecessarily large, and there is a problem that the ground butter is melted. Furthermore, if the temperature of the butter to be crushed is -15 ° C or higher, the crushed butter is likely to adhere to each other, and the butter adheres to the cutting edge so that the crushing cannot be performed. There is also a problem that the temperature of the butter must be controlled, which causes an increase in the cost of the freezing treatment.

A conventional general food cutting device is
Many of the applied foods have low mechanical strength when cutting. In addition, even if the frozen food is applied to fish and animal meat having high mechanical strength at the time of cutting, fish and animal meat are generated by the cutting blade rotating at a relatively high speed. It is a food with a high moisture content that easily absorbs frictional heat during cutting and that can easily treat chips and the like generated by cutting. As described above, the conventional general food cutting apparatus is intended for foods that are relatively easy to cut. On the other hand, frozen bulk fats and oils, such as butter, are foods that contain only about 16% of water and have high mechanical strength at the time of cutting. Friction heat is generated at the time of cutting because the blade is rotating at a relatively high speed, and the friction heat is absorbed by fats and oils. There is a problem that cutting becomes difficult due to the adhesion of oils and fats to the surface, and furthermore, there is a problem that quality of a melted cut portion is deteriorated.

[0008] As an elevating type cutting machine, for example,
Japanese Unexamined Patent Publication No. 59-8517 and Japanese Patent Publication No. Sho 59-18196 are disclosed, but these lifting type cutting machines use sharp blades to cut generally soft foods such as meat, vegetables and processed foods. It is used for. However, if the lifting type cutting machine is simply used for cutting the frozen bulk oils and fats, as seen when cutting using a kitchen knife,
There is a problem that not only the direction of the crack is not constant, it is difficult to control the crack, but also the cutting blade is caught in oil and grease, making it difficult to cut, and the risk of damage to the cutting blade is high. Further, a push-cut type cutting machine is one in which a plurality of cutting blades are arranged at regular intervals or arranged in a lattice, and cut by pressing a soft food such as bread on the cutting blade. When cutting a lump of fat or oil, the cutting blade is sandwiched between the fats and oils, making it difficult to cut or damaging the cutting blade.

As described above, in the conventional method of crushing and heating frozen bulk oils and fats and the apparatus used therefor, or the apparatus generally used for cutting food, cutting is efficiently performed while maintaining the frozen state. Or, it was not possible to make a uniform piece-like fat by cutting. For this reason, the present inventors have studied a method and an apparatus for efficiently cutting or cleaving a frozen bulk oil or fat into small pieces. As a result, the present invention has been completed based on the finding that the object can be achieved by cutting or cleaving bulk oil and fat frozen by a single-edged cutting blade. That is, the method and the apparatus of the present invention are intended to efficiently cut or cut a bulk oil or fat in a frozen state into small pieces.

[0010]

In order to achieve the above object, the present invention provides the following method and apparatus for cutting or cleaving frozen bulk oils and fats. That is, the method of cutting or cutting the frozen bulk oil or fat of the present invention uses a horizontally long cutting blade having a single blade, and within 30 mm from the end surface of the frozen bulk oil or fat, the cutting edge of the horizontally long cutting blade having a single blade is used. It is placed outward and a load is applied to the cutting blade, and by a force that pushes and expands the width of the thickness of the cutting blade, a crack is simultaneously generated in the load direction and in a direction perpendicular to the cut surface to cut or cut into small pieces. Things. Further, in the method for cutting or cleaving the frozen bulk oil or fat, a plurality of short vertical blades are installed at a right angle to a horizontally long cutting blade composed of one blade, and the cutting blade is used for cutting vertically and horizontally at the same time. Direction, a direction perpendicular to the cut surface, and a load direction of the vertical blade are simultaneously cut or cut into smaller pieces at a certain angle or less. And these methods are 0
It cuts or splits frozen bulk oils and fats at a temperature of not more than ℃.

The present invention also provides the following suitable apparatus for carrying out the above-mentioned method for cutting or cleaving frozen fat and oil. That is, the apparatus for cutting or cleaving the frozen bulk fats and oils of the present invention is a horizontally long oblong composed of a pedestal for mounting the frozen bulk fats and oils, and a single blade for cutting the frozen bulk fats and oils mounted on the cradle. A cutting blade, a frame for fixing the cutting blade, a driving unit for raising and lowering the frame, and a position of the cutting blade from the end face of the frozen bulk oil and fat.
This is a configuration provided with a holding unit for frozen bulk oils and fats for holding within 30 mm. In addition, when a cutting blade is used in which a plurality of short vertical blades are installed at a right angle on the blade surface side with respect to the above-mentioned horizontally long cutting blade, the frozen bulk oils and fats are reduced to a certain angle or less. It is suitable.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail. The present invention is to cut or cut a lump of fat or oil such as butter or margarine that has been frozen, while keeping the frozen state without thawing. The fat or oil used for cutting or cleaving according to the present invention has been frozen at a weight of about 10 to 30 kg, and the frozen bulk oil or fat is cut or cleaved at a temperature of 0 ° C. or less at the time of cutting or cleaving. If the material is frozen at 0 ° C or less during cutting or cleaving, the adhesiveness inherent in fats and oils is almost lost and the adhesiveness is reduced. Become. At 0 ° C. or higher, the contained water (about 16% in butter) undergoes a phase change from a solid phase to a liquid phase, and the viscosity of fats and oils also increases, so that cutting and cleaving becomes difficult.
In the present invention, the bulk oil and fat which has been frozen as described above is cut from the end face (side surface) of the frozen bulk oil and fat by using a horizontally long cutting blade composed of a single blade having only one surface sharpened and inclined.
The cutting edge of the cutting blade is placed outward within mm and a load is applied to the cutting blade to cut or cut.

[0013] From the end face of the block fat thus frozen
By cutting the cutting edge within 30 mm and the cutting edge consisting of one edge outward, the cutting edge can be pushed and expanded by the width of the thickness by the cutting edge, so it can be simultaneously applied in the load direction and the direction perpendicular to the cutting surface. Cracks occur and are divided into small pieces by cutting or splitting. According to this cutting or cleaving method, there is no temperature change due to frictional heat at the time of cutting or cleaving, so that no melting of the cut surface or adhesion of fats and oils to the cutting blade occurs. The present invention relates to a method of preparing a frozen bulk oil and fat from an end face.
Cutting or cleaving with a single-edged cutting blade within mm limits the direction of cracking of massive fats and oils generated at the time of cutting or cleaving, stabilizes the size of cracks, and removes large cracks and large cutting fats and oils. It does not generate and further smoothes the cut surface of the oil and fat. The cutting direction of the frozen bulk oil or fat may be a vertical direction in which a load is applied from the upper side to the lower side, or may be a horizontal direction in which the cutting blade is oriented horizontally, but is cut or cut into small pieces. In consideration of the collection of the fats and oils, it is preferable to cut or cut in the vertical direction and drop and collect the cut or cut small pieces by their own weight. Cutting or cleaving within 30mm from the end face of the frozen bulk oil or fat means that the cutting surface is pushed and expanded by the thickness of the cutting blade at the time of cutting or cleaving, and simultaneously cracks in the direction of the load applied by the cutting blade and the direction perpendicular to the cutting surface. Is easily generated, and the cut or cut oil and fat pieces are obtained as relatively uniform small pieces, and the ease of use in the next process or the load on the device and the cutting edge is reduced, so that the cut or cut is efficiently performed. That is because

The shape of the cutting blade is such that only one side of the cutting blade is sharpened in order to simultaneously cut or cut the frozen bulk oil or fat by causing cracks in the load direction and the direction perpendicular to the cut surface at the same time. A single-edged blade. The length of the cutting blade is preferably a lateral length slightly longer than one side of the frozen bulk oil to be cut. The inclination angle of the single edge is 10 to 45 °, preferably 15 to 45 °, depending on the temperature of the frozen bulk oil or fat to be cut or cut or the size of the small oil or fat to be obtained.
30 °. If the tip angle of one edge is less than 10 °,
Since the spreading of the fat or oil to be cut or cut is not sufficiently performed, a uniform small piece cannot be obtained.On the other hand, when the inclination angle exceeds 45 °, the fat or oil to be cut or cut is rapidly spread. Therefore, also in this case, the direction of the crack is not constant, and a uniform small piece cannot be obtained. The material of the cutting blade may be any material that has sufficient strength and does not generate rust.For example, 5 to 10 mm that can sufficiently withstand the load applied when cutting or cleaving frozen bulk oils and fats. It is preferable to use a stainless steel cutting blade having a thickness of about the same and reinforced by appropriate means. By using the cutting blade as described above, the frozen bulk oil and fat can be easily cut or cut into small pieces, but in order to make the piece and fat as large as possible, It is preferable to use a blade that has a plurality of short vertical blades arranged in a direction perpendicular to the side of the blade surface with respect to the cutting direction and that cuts simultaneously in the vertical and horizontal directions. By disposing the vertical blade, it is possible to simultaneously cut or cut in the load direction of the cutting blade, the direction perpendicular to the cutting surface, and the load direction of the vertical blade, to reduce the size to a certain angle or less. The vertical blade may be a single blade or a double blade, but preferably a double blade.

[0015] The present invention relates to a method and an apparatus for cutting or breaking a lump of fat or oil which has been frozen as described above with a cutting blade comprising a single blade, and to a device therefor. Will be described. First, as shown in FIG. 1, when the frozen bulk oil and fat (A) is cut or cut using a double-edged cutting blade (a ′) such as a kitchen knife or the like, a large crack together with a practically preferable crack (x) is obtained. Cracks (y) and (z) are likely to occur, and the direction of the crack is not constant, and cutting or cleaving tends to be unstable. In addition, the obtained piece-like fats and oils are not uniform. In the method of the present invention, as shown in FIG. 2, only one side is sharpened, and the cutting width is cut from the end face of the frozen bulk fat (A) by using a single-sided cutting blade (a) having an inclination. Place the cutting edge (1) of the cutting blade (a) consisting of a single blade within 30 mm, and place it on (a) in FIG.
As shown in (b) and (c), a load is sequentially applied to stabilize the direction of the crack, and simultaneously the load direction (X) and the direction perpendicular to the cut surface (lateral direction) (Y) are simultaneously made. Crack (x)
To produce small pieces of fats and oils (A ′).
The fats and oils (A ′) flaked in this way are homogenized in an extruder or a butter homogenizer in a kneading process and used as raw fats and oils for confectionery and baking, or
Remodeled to a weight of about 5 to 500 g, it becomes table oil and cooking oil used at home.
