Description

DETAILED DESCRIPTION OF THE INVENTION A. OBJECTIVES OF THE INVENTION A-1 Industrial Application Field The present invention relates to a cheese centrifugal dewatering apparatus for centrifugally dehydrating cheese, which is formed by rolling a processing system into a cylindrical shape.

E-2 Prior Art Conventionally, the centrifugal dehydrator for cheese as described above is
A rotating shaft is provided at the center of a fixed dehydration tank, cheese is attached to a cheese holder provided on the rotating shaft, and the rotation of the rotating shaft causes the cheese to revolve without rotating on its own axis, and the cheese is coated. Generally, cheese is dehydrated by centrifugal force.

E-3 Problems to be Solved by the Present Invention When cheese revolves in a centrifugal dehydration device, a compressive force toward the center of the cheese acts on the part of the cheese on the side of the revolution center axis, and conversely, the part on the opposite side An outward pulling force acts on the cheese, causing it to deform. Therefore, in the case where the cheese only revolves without rotating, as in the conventional case, the part of the cheese on the side of the revolution center axis is compressed from beginning to end, and the part on the opposite side is stretched from beginning to end. There are problems in that the threads of the cheese become intertwined with each other, making it easy to break the threads when the threads are pulled out later, and making it difficult to make the texture uniform. Therefore, an object of the present invention is to solve the above-mentioned problems by rotating cheese during centrifugal dewatering by revolution of the cheese.

B. Structure of the Invention RO-1 Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has the following features:
In the invention, a dehydration tank is provided to be rotatable in the circumferential direction thereof, and a means for driving the rotation thereof is provided, and a cheese holding means is provided in the dehydration tank for revolving the cheese with its circumferential surface in contact with the inner surface of the dehydration tank. At the same time, a means for driving the rotation of the cheese holding means is provided, and means for imparting a rotational difference between the number of rotations of the dehydration tank and the number of revolutions of the cheese is provided in both the rotational driving means, and this rotational difference causes the cheese to undergo rotational movement. The second invention is characterized in that the cheese holding means is further provided with means for causing the cheese held upright by the cheese holding means to tilt forward by centrifugal force. It is characterized by:

R-2 Effect Moisture inside the cheese is dehydrated by the centrifugal force caused by the revolution of the cheese. Further, due to the rotational difference between the rotation speed of the dehydration tank and the revolution speed of the cheese, the cheese causes rotational movement, and the direction of centrifugal force acting on each part of the cheese changes sequentially.

RO-3 Embodiment Next, an embodiment of the present invention shown in the drawings will be described.

In FIG. 1, reference numeral 1 denotes an outer wall, inside of which a cylindrical dehydration tank 2 made of a perforated plate is rotatably provided. Reference numeral 3 denotes a dehydration tank rotating shaft fixed to the center of the dehydration tank 2, and rotatably supported at the center of the outer wall 1. Reference numeral 4 denotes a cheese holder whose rotating shaft 5 is provided concentrically with the dehydration tank rotating shaft 3. As shown in FIG. 4, a plurality of cheese holding arms 6 are provided on the outer periphery of the cheese holder 4 to protrude radially. A long hole 7 is formed in the cheese holding arm 6 in the direction of the arm. A sliding body 10 consisting of an upper piece 8 and a lower piece 9 as shown in FIG. 6 is held at the tip of the cheese holding arm 6 so as to be slidable in the direction of the elongated hole 7. The sliding body 10 includes an upper piece 8 having an engagement surface 8a that engages and slides on the upper surface of the cheese holding arm 6, and a guide portion 8b that fits loosely into the elongated hole 7 on the lower surface thereof, and an upper piece 8 of the cheese holding arm 6. An engaging surface 9a that engages and slides on the lower surface, and a guide portion 9b that loosely fits into the elongated hole 7.
and a lower piece 9 formed on the upper surface, respectively, and by connecting these with bolts and nuts 11 so as to sandwich the cheese holding arm 6, the sliding body 1
0 is attached to the cheese holding arm 6 so that it can move along the elongated hole 7. In addition, the engagement surface 9 of the lower piece 9
a is formed in a tapered surface where the base side of the cheese holding arm 6 descends, and the sliding body 1 consists of a lower piece 9 and an upper piece 8.
0 (base side of the cheese holding arm 6) is designed to move up and down. Reference numeral 12 denotes a return spring installed between the rear lower part of the lower piece 9 and the base of the cheese holding arm 6. Reference numeral 13 denotes a support shaft formed by extending the upper part of the front bolt 11 provided on the sliding body 10, and a cheese holder 14 is rotatably fitted onto this support shaft. The cheese 15 is attached to the outer periphery of the cheese holder 14 by fitting a bobbin 16 for the cheese 15. The dehydration tank rotation shaft 3 and the rotation shaft 5 of the cheese holder are both rotated in the same direction by a drive motor 17, and the dehydration tank rotation shaft 3 is rotated by the transmission gear 1.
8, 19 and a belt 20, and the rotating shaft 5 of the cheese holder is transmitted through transmission gears 21, 22 and a belt 23. Furthermore, the reduction ratio of the transmission gear is set so as to create a difference in the rotation speeds of both rotating shafts 3 and 5.

Next, the dehydration work in this example will be explained. In a non-drying operation state in which the cheese holding arm 6 is stopped, the sliding body 10 is positioned toward the base of the cheese holding arm 6 as shown in FIG. 2 by the pulling force of the spring 12. In this stopped state, cheese 15 is attached to each cheese holder 14 provided on the sliding body 10 of each cheese holding arm 6. Thereafter, the drive motor 17 is driven to rotate the dehydration tank 2 in one direction, and at the same time, the cheese holding arm 6 is rotated in the same direction to cause the cheese 15 to revolve. Due to the centrifugal force caused by the rotation of the cheese holding arm 6, the sliding body 10 is moved against the cheese holding body 6 against the spring 12, as shown in FIG.
The outer peripheral surface of the cheese 15 comes into contact with the inner surface of the dehydration tank 2. At this time, if the cheese 15 is a tapered cheese as shown in the figure, the sliding body 10
The rear part moves upward until the tapered engagement surface 9a comes into contact with the lower surface of the cheese holding arm 6, and the tapered cheese assumes a forward-leaning posture, and the entire length of the outer circumference of the cheese 15 is brought into contact with the inner surface of the dehydration tank 2. Contact. Note that the cheese 15 is not brought into pressure contact with the dehydration tank 2 transiently due to the contact of the engagement surface 9a. Due to the revolution of this cheese 15,
The water in the cheese 15 is centrifugally dehydrated. Moreover, since there is a difference between the rotation speed of the dehydration tank 2 and the revolution speed of the cheese 15, the cheese 15 causes rotation. When the cheese 15 revolves and rotates in this way, the direction of centrifugal force acting on each part of the cheese 15 changes sequentially, and compressive force and tensile force alternately and regularly act on each part. When this dehydration work is completed and the drive motor 17 is stopped, the cheese holding arm 6 is stopped and the sliding body 10 is moved by the spring 12.
The force returns to the original state shown in FIG. Then, the cheese 15 is taken out of the dehydration tank. still,
The above embodiment is for a tapered cheese, but in the case of a straight cheese whose upper and lower overall lengths are the same diameter, the sliding body 10 does not need to move its rear part up and down so that the cheese tilts forward, but simply moves back and forth. A structure that allows

(C) Effects of the Invention As described above, according to the present invention, compressive force and tensile force are alternately and regularly applied to each part of the cheese due to the rotation of the cheese, and the same compression force is applied to each part. Force and tension act. Therefore, as in the conventional case,
Compared to cheese where one part is compressed all the time and the opposite part is pulled all the time, the threads in the cheese are less entangled, the threads are prevented from breaking when pulled out, and the texture is uniform throughout. There are some features that make it easier to use. Furthermore, by providing a means for tilting the cheese forward by centrifugal force, even a tapered cheese can bring its entire outer periphery into contact with the inner surface of the dehydration tank, thereby achieving the same effect as described above.
