As the mixing of particles and solvents is an important part of the pharmaceutical process, the mixing equipment plays an important role in the pharmaceutical industry. It is understood that the gravityless mixer makes full use of the principle of convection mixing, that is, the use of materials in the mixer to throw up the movement of the formation of a fluid layer, resulting in instantaneous weightlessness, so that it achieves the best mixed-effect state. Non-gravity mixers can be roughly divided into two types: one is an ordinary gravityless mixer, and the other is a flying blade type gravityless mixer. The latter is mainly aimed at a type in which the material contains fibers and is cut after the cutting of the flight knife.
The non-gravity mixer horizontal cylinder body is equipped with two-axis rotating reversed blades, and the blades are rotated at a certain angle to rotate the material in the axial and radial directions so that the materials can be quickly and uniformly mixed; in order to reduce the replacement of wearing parts of the equipment The cost, paddle blade can be made into two-piece type, a small movable blade can be placed on the blade base, and the worn small blade can be replaced directly, which is economic and efficient; the discharge form is generally a pneumatic flap valve, and the arc valve is closely embedded The inside of the cylinder is flush with the inner wall of the cylinder, and there is no material accumulation and mixed dead angle phenomenon; the standard type has the points of large opening and small opening of the door, and the large opening door is opened to the side of the cylinder, and the discharging is clean and fast, and the residue is small.
The rotation speed of the shaft driven by the reducer and the structure of the blade will reduce the gravity of the material. With the lack of gravity, the difference in the particle size and specific gravity of each material is ignored in the mixing process. The intense mixing motion shortens the time for one mixing, faster and more efficient. Even if the material has a difference in specific gravity and particle size, a good mixing effect can be achieved even if the stirring blades of the staggered arrangement are quickly and violently tossed and thrown.
With the continuous development of the pharmaceutical industry, the prospects for the development of hybrid equipment in the pharmaceutical field are even more unpredictable. Only by continuously advancing, can companies achieve long-term development. Therefore, relevant manufacturers must develop toward automation and sterility.
In recent years, with the continuous development of the requirements for the development of the pharmaceutical machinery industry, all equipment is undergoing upgrades and transformations, and technologies are constantly being improved. The gravityless mixer is a device that is produced under high demand.
