Definitions

  • Powder raw material and liquid raw material mixing apparatus and method for producing a mixture using the mixing apparatus
  • the present invention relates to a continuous mixing technique of a powder raw material and a liquid raw material.
  • the ideal final state of mixing is that each flour particle retains moisture at an even rate.
  • several phenomena have occurred in the process of mixing, preventing the ideal state from being reached.
  • One of the inhibiting factors is a phenomenon in which water does not easily penetrate into flour.
  • Flour particles have a strong affinity with air. Therefore, mixing does not occur easily because the air surrounding the flour particles prevents the water and flour particles from approaching. In this phenomenon, even if water is poured into a container containing flour and left for a while, the mixing of the two does not proceed! / You will also realize by observing the child.
  • Another phenomenon that hinders the reaction is the change of the state of flour by the reaction of flour and water. Assume that the required amount of moisture has been given to the flour particles. Then, gliadin and glutenin, which are the main components of the protein contained in wheat flour at 6% to 15%, react with water. As a result, a protein called dulten that has both stickiness and elasticity is produced.
  • the above numerical value (ratio of the weight of water to wheat flour) is referred to as a water addition rate.
  • the reason for lowering the water content at the time of koji making is to prevent the dough from sticking to a koji roll for forming koji.
  • the dough for koji has problems such as the destruction of the dartene structure and the disappearance of the so-called “koshi” immediately after the bread dough is made.
  • Patent Document 1 As another mixing technique, there is a “continuous high-speed stirring and mixing mixer” (Patent Document 1). When mixing flour and water with this device, water atomized by the action of a paddle rotating in the casing comes into contact with the flour that flows in the axial direction while rotating, and continues to bow. Kneading is performed downstream. [0020] However, since water has a structure in which water is injected at a single location outside the casing with a water pipe, there is no guarantee that a uniform dough will be produced at the first contact between water and flour. In order to cover this, a kneading process is provided in the subsequent stage to achieve a certain level of uniformity, but this is insufficient.
  • the kneading also destroys the network structure of Dalten, and is discharged out of the apparatus with poor quality.
  • the mixture becomes a so-called rag and can be used as it is as a dough for baking or baking!
  • Patent Document 2 a thin film is supplied that is quantitatively supplied to the center of a rotating disk and flows radially onto the disk surface after contact with the disk, and the inner surface of the cylindrical wall drops onto the disk due to overflow.
  • a mixing device that is brought into contact with a liquid to obtain a continuous mixture.
  • the mixture discharged from the mixing device has a so-called rag shape in which dough with insufficient moisture surrounds dough with excess moisture. Therefore, the raw dough cannot be used for bread making or koji making.
  • Patent Document 3 “Method of hydrolysis and maturation in the production of wheat flour kneaded products” aims at bringing flour and water into a fine particle state and bringing them into direct contact with each other.
  • Patent Document 3 prevents re-spraying onto particles that have been combined with fine water droplets. Therefore, it is difficult to achieve uniform mixing as intended without a mechanism for selectively spraying particles with delayed bonding. It is the same in that it is difficult to expect a sufficient effect in other examples in Patent Document 3. In other words, the specific method of ideal blending that we are aiming for is presented as a fool.
  • the problem of the prior art in mixing powder and liquid is the problem to be solved by the present invention.
  • the fundamental problem of the prior art is that in order to achieve complete mixing, it is necessary to knead after mixing V, just.
  • the present invention aims to provide a method for realizing complete mixing without a kneading step.
  • the reaction between the two products generated after mixing is an important substance, such as the mixing of flour and water.
  • the importance of the subject of the present invention is extremely large.

Abstract

L'invention consiste à injecter un matériau poudreux à un débit prédéfini au centre d'un disque, tournant à une vitesse modérée, pour constituer une mince couche de poudre près de la périphérie du disque. D'autre part, un pulvérisateur rotatif à grande vitesse est installé sur le même axe que le disque rotatif et un matériau liquide, qui est injecté à un débit prédéfini, est pulvérisé de manière continue et ainsi irradié. Ainsi, le matériau liquide est pulvérisé à grande vitesse de derrière vers l'écoulement de couche de poudre ayant été pulvérisé sur le disque rotatif. Ainsi, une liaison homogène et instantanée est formée de manière continue au niveau microscopique entre ces matériaux de sorte que l'on peut obtenir de manière continue un mélange homogène du matériau poudreux et du matériau liquide. En mélangeant de façon homogène le matériau poudreux et le matériau liquide dès le départ, l'agitation devient superflue, ce qui permet de protéger le mélange de toute perte de qualité. De plus, il devient possible de raccourcir remarquable le traitement et de simplifier l'appareil. En cas d'utilisation dans le mélange d'un matériau poudreux consistant principalement en farine de froment avec un matériau liquide composé principalement d'eau, en particulier, l'appareil ou le procédé tel que décrit plus haut permet de fabriquer du pain ou des pâtes d'excellente qualité grâce à un procédé raccourci et simplifié.
