The present invention relates to a spherical molding apparatus for molding a spherical material, such as pills, spherical food, spherical feed, and more particularly, to a spherical molding apparatus capable of improving the productivity of a spherical product quickly and precisely.

As is known, products that are widely known as spheres include pills, sphere foods, sphere feeds, etc. These spheres have the advantages of being convenient to take, easy to move and store, and moderate to absorption.

On the other hand, these spherical products are released into the product after the spherical shape is processed by a spherical molding apparatus known as the 'refiller'.

Such conventional recirculators are configured to extrude dough material into strand shapes, such as noodle strands, through an extruder and to pass the extruded extrudate between a pair of rotating forming rolls to form a sphere. In particular, the forming roll has a plurality of forming grooves formed on its outer circumferential surface, the forming groove is configured to press the strand-like extrudate to form a spherical shape.

On the other hand, such a conventional reversing machine is configured such that the extruder extrudes the rhythmically shaped extrudate vertically downward, and correspondingly, a pair of forming rolls are arranged on both left and right sides of the extrudate to form an extrudate into a spherical shape.

As described above, the conventional reversing machine has a complicated arrangement of the whole apparatus due to the arrangement of the extruder for extruding the dough material vertically downward, the arrangement of a pair of forming rolls on both the left and right sides of the extrudate extruded vertically downward, and the like. Not only that, but the size, volume, etc. has become large, took up a lot of work space.

In addition, the conventional reflow machine has a disadvantage in that the spherical shape of the spheres is reduced because the extrudate is not tightly adhered to the forming groove side of the forming roll due to the vertical downward extrusion structure of the extrudate.

That is, the spherical body molded by the conventional dehydrator has a disadvantage in that the shape accuracy is lowered, the defective rate of the spherical body is increased, and the productivity thereof is lowered. As a result, the waste of material is severe and the production cost and manufacturing cost of the spherical body are increased.

The present invention has been devised in view of the above, and by applying a structure in which the extrudate is hermetically adhered to the forming groove side of the forming roll, it is possible to improve the shape accuracy of the spherical body and to greatly improve the productivity of the spherical molding. The object is to provide a device.
