First, the working principle of the trough mixer
The moving parts of the mechanical agitator also shear the liquid when it is rotated. The liquid is also subjected to shearing action when flowing through the wall and various fixing members installed in the container. These shearing actions will cause many Local eddy current diffusion. The convection diffusion and eddy current diffusion caused by stirring increase the surface area of ​​molecular diffusion between different liquids and reduce the diffusion distance, thereby shortening the time of molecular diffusion. If the viscosity of the liquid to be mixed is not high, it can be brought to a random mixing state within a short stirring time; if the viscosity is high, a longer mixing time is required.
Second, the application of the trough mixer
The utility model has the advantages of compact structure, simple operation, beautiful appearance, small occupied area, convenient cleaning and good mixing effect. The mixer unit rotates the S-type stirring paddle by mechanical rotation, pushes the material to reciprocate and rotates evenly, and uses electric control during operation. The mixing time can be set and the machine can be automatically stopped at that time, thereby improving the mixing quality of each batch of materials. The trough mixer is connected to the power supply, sets the mixing time, presses the switch, and reciprocates the material through mechanical transmission to obtain a uniform product. The whole machine is made of all stainless steel, which is simple and convenient to use, and is suitable for pharmaceutical, chemical and food factories. Wait.
Third, the characteristics of the trough mixer
The mixing of the liquid mainly relies on a mechanical agitator, a gas stream and a jet of the liquid to be mixed, etc., so that the material to be mixed is agitated to achieve uniform mixing. The agitation causes a portion of the liquid to flow, which in turn pushes the liquid around it, with the result that a circulating liquid flow is formed within the solution, and the resulting diffusion between the liquids is referred to as bulk convection diffusion. For liquids of different density, composition, and incompatibility, the shearing action caused by the agitation and the strong turbulence shred the dense liquid into small droplets and uniformly disperse it into the main liquid. The flow rate of the liquid produced by the agitation must be greater than the settling velocity of the droplets.
