DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a food crushing apparatus. In particular, the present invention mechanically crushes and disperses tissues such as living cells of the food sample by placing a food sample together with a diluent in a storage bag and repeatedly pressing the sample from the outside during the test for food microorganisms. It is suitably applied as a homogenizer used for suspension. Further, the present invention is applicable to food crushing apparatuses in general, and can be applied to, for example, a food mixer or juicer.

[0002]

2. Description of the Related Art As shown in FIG. 21, a conventional homogenizer includes a main body 2 having a driving mechanism (not shown) therein, and a paddle room 3 formed on the front side of the main body 2.
Two paddles 4a, 4a, 4a, 4b, which are provided in parallel on the left and right sides and alternately reciprocate by a driving mechanism in the main body 2.
b, and a door 5 that is provided to be openable and closable on the front opening surface of the paddle room 3 to seal and fix the open end of the sample storage bag 1.

In this conventional homogenizer, a storage bag 1 containing a sample together with a diluent is set between paddles 4a, 4b and a door 5 in a paddle room 3 on the front side of a main body 2. Then, the paddles 4a and 4b are alternately reciprocated as shown by arrows, and the storage bag 1 containing the sample is moved.
Was pressed against the back surface of the door 5 to crush and disperse the sample inside.

Further, the sample in the storage bag 1 is repeatedly subjected to rapid pressurization and decompression by the physical pressure and the water pressure acting at the same time. It was supposed to be possible.

[0005] However, depending on the configuration of such a conventional homogenizer, the sample may not be sufficiently crushed and dispersed.

That is, since the front sides of the two paddles 4a and 4b and the rear side of the door 5 are both formed in a flat shape, the storage bag 1 is pressed between the door 5 and one of the paddles 4a. Then, before the sample in the storage bag 1 receives a sufficient pressing force, the other paddle 4 which has not been pressed yet is operated.
It escapes to the b side together with the diluent. Thereafter, when the storage bag 1 is pressed by the other paddle 4b, before the sample in the storage bag 1 receives a sufficient pressing force by this, the diluting liquid is applied to the one paddle 4a side which has already been retracted at that time. Escape with. Thus, even if one paddle of the paddles 4a and 4b that alternately reciprocate tries to perform a compression operation, the sample moves to the other paddle side together with the diluent every time the paddles 4a and 4b try to press, and cannot receive a sufficient pressing force. Was repeatedly generated.

Therefore, in the homogenizer having the above structure, a sufficient pressing force cannot be applied to the sample in the storage bag 1, the crushing / dispersing efficiency is poor, and the sample cannot be suspended. Has the disadvantage of requiring a long time.

In order to eliminate such disadvantages, the present inventor has proposed, as an improvement of the above homogenizer, Japanese Patent Application No. 6-1.
01528, it was proposed to form irregularities 6a and 6b whose surfaces change in a smooth curve substantially over the front surface of a pair of paddles reciprocating alternately (FIG. 22).

In this case, the paddles 4a and 4b alternately repeat the stroke motion to move the storage bag 1 containing the sample into the door 5
When pressed against the back, the unevenness 6a, 6b on the front of the paddle
Thereby, resistance can be given to the movement of the sample in the storage bag 1 to the paddle side where the pressing operation is not performed, and the crushing dispersion and suspension of the sample are promoted.

On the other hand, a simple manual homogenizer has been conventionally known. This manual homogenizer is shown in FIG.
As shown in FIG.
The opening end of the storage bag 1 containing the sample is closed with a clip 9 or the like, and this is placed on a flat base, and the roller 8 is repeatedly moved in the direction of the arrow from above. This was used to grind the sample inside.

[0011]

However, in the homogenizer (FIG. 22) proposed in the above-mentioned Japanese Patent Application No. 6-101528, irregularities 6a and 6b are formed on the front side of a pair of paddles 4a and 4b. Thus, when the sample in the storage bag 1 is pressed by one paddle, the movement of trying to escape to the other paddle side can be restrained to some extent, but it is still insufficient.

Although the paddles 4a and 4b are formed with concave and convex shapes 6a and 6b on the front side, the paddle shape as a whole remains flat, and the sample in the storage bag 1 is put together with the diluent into the bag. Because you only hit it flat from the surface,
The pressing operation by the paddles 4a and 4b is weakened due to the great resistance of the diluent, and it has been difficult to apply sufficient pressure to the sample inside.

[0013] Accordingly, there has been a demand for the development of a homogenizer that can more efficiently and crush and disperse a sample in a short time.

In the homogenizer shown in FIGS. 21 and 22, a high water pressure is generated in the diluent in the storage bag 1 due to the impact force exerted when the paddles 4a and 4b press the storage bag. In order to prevent breakage of the storage bag 1, the storage bag 1 had to be thick and strong.

Further, a drive mechanism for causing the paddles 4a and 4b to perform a stroke movement must be provided in the main body 2, so that noise and vibration peculiar to the stroke movement engine are large. Further, in order to prevent the homogenizer from moving during operation due to this vibration, it was necessary to increase the overall weight. Furthermore, the main body 2 having a built-in drive mechanism for performing a stroke motion is forced to have a shape protruding rearward, and has been increased in size.

Further, in order to set the storage bag 1 between the paddles 4a, 4b and the door 5 or to remove the storage bag after the operation is completed, the door 5 must be opened and closed after stopping the movement of the paddle. The storage bag could not be automatically fed and ejected.

On the other hand, in the conventional manual homogenizer using a simple single roller (FIG. 23), the diluting liquid is hardly collected and removed in the forward direction of the roller, so that further advance of the roller is hindered, and It was not easy to uniformly apply the roller over the entire surface of the bag, and the sample in the storage bag could not be sufficiently crushed and dispersed to be suspended. In addition, manual operation of the roller requires a great deal of labor and time.

Therefore, the present invention solves the above-mentioned problems of the prior art, and provides a novel food which can sufficiently disperse and suspend a food sample in a storage bag by crushing and dispersing it in a sufficiently short time. It is an object to provide a crushing device.

It is another object of the present invention to reduce the noise and vibration of the food crushing apparatus and to reduce the weight and size of the apparatus.

Further, the present invention reduces the impact force applied to a storage bag for accommodating a food sample when crushing and dispersing the food sample, thereby reducing the cost of the storage bag without requiring an excessively thick or special material. The purpose is to enable the use of storage bags.

Still another object of the present invention is to provide a food crushing apparatus capable of automatically feeding and discharging a storage bag containing a food sample.

Another object of the present invention is to provide a manual food crusher having a large crushing force.

According to the present invention, when the pressing roller rotator rotates while moving relative to the storage bag and presses the storage bag, the free rotation roller provided on the pressing roller rotator stores the free roller. While eliminating the diluent in the bag, the sample inside can be sequentially crushed without being subjected to a large resistance due to the diluent, crushed thoroughly, and the sample can be finely crushed and dispersed to sufficiently suspend the sample. . Since the pressing roller rotating body is in contact with the side surface of the storage bag and presses while rotating,
The impact force applied to the storage bag is small, and the storage bag is not damaged. Therefore, no special strength is required for the material of the storage bag, and the thickness can be reduced, so that an inexpensive storage bag can be used. According to the present invention, since a member that reciprocates back and forth like a paddle used in a conventional homogenizer is not used, noise and vibration associated with operation of a drive mechanism are reduced and weight is reduced,
Further, the depth of the main body of the apparatus can be reduced to reduce the size. Further, by using a plurality of pressing roller rotating bodies to sequentially crush different portions of the storage bag simultaneously, it is possible to further increase the crushing force against the sample inside. In particular, by employing a configuration in which a plurality of pressing roller rotating bodies are orbitally moved, the storage bag can be sequentially and repeatedly crushed, the crushing force on the sample is dramatically increased, and the sample is finely crushed and dispersed. The suspension can be sufficiently suspended, and the operation time can be significantly reduced. Further, in the present invention, by automatically feeding and discharging the storage bag, the storage bag is supplied to the homogenizer, which is crushed and dispersed by the free rotating roller of the pressing roller rotating body, and then the storage bag is discharged. A series of processes can be fully automated. As a result, the process of microbial testing is unmanned, labor costs are reduced,
Secondary contamination of the sample due to manual intervention can be prevented, and the accuracy of the test can be ensured. The present invention is not limited to a homogenizer but can be widely applied to food crushers such as mixers and juicers.
