Embodiment 1

[0061] (Manufacturing example of humidified powder of α-starch)

[0062] At the top of the mixing granulation chamber 12, spray 64cm continuously by the spray nozzle 14 3 / min of clear water, and at the same time, 3.63kg / min of gelatinized starch is supplied from the powder supply port 16, and then compressed air is supplied from the air supply nozzle 18. Simultaneously, at the bottom of the mixing and granulating chamber 12 , while rotating the rotary mixing and stirring disk 32 at 1000 rpm, the humidified powder of gelatinized starch was continuously produced. As a result, pregelatinized starch excellent in water solubility and composed of 10% to 13% humidified powder having a uniform particle size can be produced with a high yield of about 100%.

Embodiment 2

[0064] (Manufacturing example of polymer water-absorbing agent)

[0065] At the top of the mixing granulation chamber 12, spray 225cm continuously by the spray nozzle 14 3 / min of clear water, while supplying 4.5kg / min of polyvinyl alcohol powder from the powder supply port 16, and then supplying compressed air from the air supply nozzle 18. Simultaneously, at the bottom of the mixing and granulation chamber 12, a humidified powder of polyvinyl alcohol was continuously produced while the rotary mixing and stirring disk 32 was rotated at 1000 rpm. As a result, a high-molecular water-absorbing agent composed of 3% to 5% humidifying powder having a uniform particle size and excellent water-absorbing properties can be produced with a high yield of about 100%.

Abstract

The invention relates to a method of powder / liquid continuous mixing particle production. Wherein, said method comprises that sealing the top of hopper mixed particle producing room (12); the center at the top uses ejector (14) to continuously eject liquid downwards; the powder outlet (16) at the circumference of ejector disperses the atomized liquid to the powder; and the gas ejector (18) at the circumference of powder outlet feeds gas as the protective air film (Af) that avoiding dispersing the fed powder; therefore, the powder and liquid can continuously contact to form mixed particle (G); and the bottom of room (12) via the rotation of mixing disc (32) can make the air passive pressure, to generate eddy flow, to accelerate the particle (G) generation, and shear or mix the particle (G), to form and discharge uniform particles (G).

Description

technical field [0001] The present invention relates to a powder / liquid continuous mixing granulation method and device for continuously producing a powder / liquid continuous mixing granulation method and device for continuously producing a powder granule with an increased volume and excellent water solubility by humidifying the powder for granulation. Background technique [0002] In the past, because the water-soluble polysaccharide powder is a dried fine powder, it is easy to cause the fine powder to fly in the air when the powder is processed, which is the so-called dusting. There are also sanitary problems such as the workshop being polluted by dust. In addition, water-soluble polysaccharide powder has a disadvantage of causing foaming when dissolved in water due to its poor solubility. In order to solve the problem of such water-soluble polysaccharide powder, there are methods of increasing the particle size of the powder through a granulation process or the like, and ...
