Description

  The present invention relates to a mixer cutter provided in a mixer for mixing food, beverages, and the like, and a mixer food production machine provided with the mixer cutter.

  Traditionally, mixers are used to make ingredients, mixtures of ingredients and liquids, shaved ice, and the like. Generally, a mixer has at least a mixer container and a mixer cutter provided in the lower part of the mixer container. Originally, the method of using a mixer was supposed to set and use a mixer container having an optimal capacity.

  However, it is difficult to always prepare mixer containers and mixer bodies having different capacities. As a result, when a mixer having a large capacity with respect to the target amount was used, the created viscous fluid vigorously moved upward, making mixing difficult. That is, the blade in the upper region of the blade fixing part winds the viscous fluid upward, and the food solid that must be broken and mixed remains. (For example, Patent Document 1)

Japanese Patent Laid-Open No. 2003-14956

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a mixer cutter capable of mixing an object while mucus fluid does not move upward and remains in the vicinity of the mixer cutter even when a mixer having a capacity larger than the target amount is used. .

In order to achieve the above object, the present invention uses the following means.

(Invention of Claim 1)
According to the first aspect of the present invention, a mixer food is produced by providing a mixer cutter at the bottom of the mixer container, setting the rotation speed of the mixer cutter to 15,000 to 25,000 revolutions per minute , and pulverizing rice cakes , rice or rice with the mixer body. The mixer cutter has a rotation shaft, a shaft support portion, and a blade portion, and the rotation shaft is provided with a blade fixing portion that fixes a blade center of the blade portion. The blade fixing portion upper region and the blade fixing portion lower region are set with a substantially horizontal plane where the blade fixing portion is present as a boundary, and the outside of the shaft support portion is formed in a truncated cone shape, The height of the frustum-shaped shaft support portion is set to 20 mm to 40 mm, and the shaft support portion is provided with a bearing and a space for the rotating shaft. Heat from the rotating shaft is insulated, and the blade portion has a horizontal blade and a blade with an inverted corner that move only in the substantially horizontal plane and the lower portion of the fixed portion. The lower angled blade is substantially horizontal and has a shape along the frustoconical shape and is provided at an interval, and the tip of the lower angled blade moves in the vicinity of the flange. It is characterized by that.

(Invention of Claim 2)
The invention according to claim 2 is the mixer food manufacturing machine according to claim 1 , wherein the distance between the outer surface of the shaft support portion and the tip of the blade with the angle bevel is 1.5 mm to 5.5 mm, The height from the top of the support portion to the center of the blade is 4 mm to 7 mm.

(Effect of the Invention of Claim 1)
According to the first aspect of the present invention, the blade of the blade portion does not exist in the upper region of the blade fixing portion as in the prior art, and the blade portion moves only in the lower region of the fixing portion. Therefore, the force to wind up the viscous fluid in the mixer container is small, and the food and fluid can be broken and mixed even if the capacity is smaller than that of the mixer container.
Further, according to the present invention, the outer side of the shaft support portion is formed in a truncated cone shape, and the blade with an inverted corner is along the shape. As a result, a phenomenon in which the behavior of the fluid is locally disturbed does not occur, and mixing is not hindered by a vortex such as a puddle.

When the frustum-shaped shaft support part is used, the object existing at the bottom of the mixer moves to the cutting and mixing position of the lower angled blade, and even a small amount of objects (food, beverages, etc.) can be uniformly broken and mixed. .
In nursing care and childcare of infants, food is often crushed with a mixer in advance to improve digestion.
For example, whole rice bran is a non-uniform food with large changes in starch quality over time. This is not suitable for people with severe dysphagia. On the other hand, cocoons made using a mixer (commonly called mixer cocoons) are not sticky and are easy to swallow infants, sick people, and elderly people, and have attracted attention in recent years. Under such circumstances, mixer food making machines have been developed. A mixer food making machine using this mixer cutter is optimal for providing the above-mentioned mixer bowl and the like.
Furthermore, this mixer food manufacturing machine can solve the problem of the bearing being burnt by the heat of the rotating shaft by the cooling action of the space, and can enable the blade portion to rotate at high speed.

(Effect of invention of Claim 2)
  The distance between the outer surface of the shaft support portion and the blade with the inverted corner is preferably set to a numerical value according to claim 2.
  With this setting, the amount of food that stays in the vicinity of the tip of the lower angled blade during rotation is reduced, and the space between the apex of the support part and the blade mounting part makes it difficult for the processed material to accumulate and easy to mix. Easy to clean after use.
