Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a juicer, and relates to a structure in which a cutting blade cuts and crushes a material to be cooked, and a squeezing section squeezes the juice.

[Technical background of the invention and its problems]

Conventionally, this type of juicer is known as the Japanese Utility Model Publication No. 45-32604
A cutter with a cutting blade is disposed at the inner bottom of a centrifugal separation basket as described in the publication, and the material to be cooked that is input through the input port is cut and crushed by the rotating cutter.
A configuration was adopted in which the solid content of the dregs was centrifuged from the juice content at the rotation of the centrifugal separation corner. This conventional centrifugal juicer has drawbacks such as air bubbles entering the juice, which easily destroys vitamins, and the rise of air bubbles causing the juice to separate into two layers.

Furthermore, in conventional centrifugal juicers, the rotational speed of the centrifugal separation corner is increased to 10% in order to increase the juice extraction effect.
000 times per minute, it has the disadvantage that vibrations and noise are likely to occur due to imbalance due to adhesion of pomace residue.

For this purpose, for example, as described in Japanese Patent Application Laid-Open No. 56-72813, a case body surrounds a rotary body having a spiral cutting and crushing part and a pressing part continuous to the cutting and crushing part. The material to be cooked that is inputted from the input port of the case body is cut by the rotation of the rotary body, the material is cut and crushed in the crushing section, and sent to the pressing section. A juicer has been developed that is configured to squeeze With this type of compression juicer, air bubbles are not mixed into the juice, the juice does not separate, and the vibration and noise are small, but since the ingredients to be cooked are gradually crushed, Processing time is long,
A force is required to crush the ingredients, and in particular, if the area of the input port for the ingredients to be cooked is expanded to increase the amount of ingredients supplied and shorten the processing time, the torque of the electric motor needs to be increased, which can be expensive. It has some drawbacks.

[Purpose of the invention]

The present invention was made in view of the above-mentioned drawbacks, and the material to be cooked is cut and crushed by the cutting blade of the cutter provided on the upper surface of the rotating body, and the cut and crushed material is transferred to the squeezing part on the circumferential surface of the rotating body. To provide a juicer which extracts and separates juice by squeezing the material, applies pressure so that the maximum squeezing force is applied to the material especially at the lower part of a rotary body, prevents air bubbles from being mixed into the juice, and provides a juicer with low vibration and noise. It is something.
