Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ceramic rotary blade for cutting food.

Traditionally, in the food sales industry that sells meat, ham, bread, etc., these foods are cut into predetermined thicknesses and sizes and displayed in stores, but recently they have been cut into predetermined thicknesses and sizes and displayed in stores. It has become common for products with a certain thickness to be cut immediately at the time of sale. In this way, a cutting device that cuts food to a desired thickness is one in which the food to be cut is placed in a predetermined position, and the cutting operation is automatically performed by specifying the thickness, etc. It has gradually become widely used. In this way, many disc-shaped rotary blades are used in devices that cut food, especially into a predetermined thickness, and these rotary blades are made of steel, stainless steel,
The mainstream is a disc-shaped rotating blade made of metal such as tungsten-molybdenum alloy.

However, when the rotating blades made of steel, stainless steel, etc. mentioned above rotate at high speed and cut food, the metal tools tend to transfer to the food. There is a growing tendency for people to shy away from it.

In addition, there is a risk of rusting due to direct contact with foods containing moisture, salt, etc., which not only deteriorates cutting characteristics but also makes it unhygienic.

In addition, because metal rotary blades have low hardness, their service life is short (about - months) even under normal usage conditions, and the degree of wear is high (and when cutting a large amount of food, they are often The rotary blade must be replaced every now and then, and maintaining the cutting device with good cutting characteristics requires manpower, and the cost of replacement blades is also high.

In view of the above-mentioned drawbacks of conventional food cutting rotary blades, the present invention has particularly excellent wear resistance, can maintain excellent cutting performance over a long period of time, and eliminates the risk of metallic odor transferring to food. The aim is to create a rotating blade that is unlike any other.

Embodiments of the present invention will be specifically described below with reference to the drawings.

Figure 1 shows the plane of the rotary blade 1. As a component of the rotary blade 1, 2 is a metal disc-shaped body made of stainless steel or the like, and the central part is fixed to a rotary drive shaft (not shown). For this purpose, a mounting hole 2a and a screw hole 2b are drilled, and a screw hole 2c is provided at the periphery for screwing and fixing a plurality of blade parts jA3.
It's the top.

Among these, the blade member 3 is composed of a ceramic body such as alumina (81λo3) and zirconia (Zr02), and its cross-sectional shape is sharp to form a blade on the outer peripheral end surface as shown in Fig. 2. Grinding and polishing are done.

In this case, a multi-blade member 3 made of a ceramic body is attached to the metal disc-shaped body 2 by inserting a screw 4 into a screw hole 2c provided in the metal disc-shaped body 2 so as to form an outer peripheral edge thereof. .

The rotary blade 1 of the present invention is constructed as described above, and is made of an alumina ceramic containing 99% M of alumina and a partially stabilized zirconia ceramic, each of which has the following components:
As in the embodiment shown in FIG. 1, a blade member 3 equipped with blades having a cutting edge angle θ at intervals of 5 degrees in the range of 5 to 55 degrees is provided with the same cutting edge angle on the outer periphery of the same metal disc-shaped body 2. Alumina,
Four blade members each made of zirconia ceramic are screwed and fixed to form an integrated rotary blade 1. In this way, the rotary blades 1 each having a semicircular blade member made of alumina or zirconia ceramic and having different edge angles θ were attached to a general-purpose cutting device (not shown), and the blades were rotated at 550 revolutions per minute. Table 1 shows the results of experiments in which various foods such as meat, ham, and white bread were cut under the same conditions. Note that the rotary blade 1 used in this experiment was subjected to a cutting experiment of five pieces at each angle, and the judgment was made based on the overall results.

As is clear from the results shown in Table 1. Therefore, it is thought that a blade with a large edge angle is suitable for cutting relatively hard J-cut objects.

From the experimental results described in Section 2, it is clear that the cutting edge angle of a rotary blade used for cutting food, especially to form alumina or zirconia ceramic body with a minimum of the parts that make up the blade, is 10.
It has been found that a temperature of about ~45 degrees, preferably between 25 and 35 degrees, is best.

As described above, according to the present invention, the rotary blade is constructed by attaching a plurality of ceramic bodies each having a blade part formed on the outer periphery of a metal disc-shaped body, so it has extremely excellent cutting characteristics and great durability. Its abrasive properties allow it to retain its cutting properties over a long period of time, and there is no risk of rusting, making it extremely hygienic and does not transfer metal odors to food.Furthermore, the blade member is split. Therefore, it is possible to provide a rotary blade for cutting food that has good productivity, is inexpensive, and can withstand long-term use.
