For us to drink a cup of steaming coffee at home, we need to prepare a coffee machine, according to the taste of the production method is different, time-consuming and laborious, and instant coffee is to solve this popular demand. For instant coffee manufacturers, the mixing process is generally based on mixing equipment, but which mixing equipment will have a better mixing effect, and efficient mixing equipment will also directly affect its quality and taste.
Instant coffee has a high demand for taste, which requires efficient mixing equipment to achieve a more uniform mixing. Different taste of coffee, the formulation of different processes, will add some trace elements according to the taste. According to the proportion of good coffee powder need to be mixed after packaging, the same batch of coffee powder mixed more uniform taste consistency is better, if the mixing is not uniform, the same batch of coffee powder between different packages will appear taste deviation, affecting the quality of the product, which requires the mixing capacity of the mixing equipment is relatively high.
Traditional double-cone mixer, single-cone mixer, three-dimensional mixer, V-type mixer, all use the principle of force diffusion mixing, the advantage is that there is no dead Angle mixing, the disadvantage is that the added trace elements can not be effectively mixed evenly, the loading rate is low, generally only 40-50%; There is also a traditional forced shear mixing machine, such as a single screw mixer, screw belt mixer, the advantage is that there is a screw belt forced mixing inside the barrel, the micro local mixing is more uniform, the disadvantage is that the material has no macroscopic convection, mixing dead Angle, discharge residue. The above two types of mixers are traditional single-principle mixing equipment, which can be used for products with low uniformity requirements.
There is also a dual power mixing equipment with gravity diffusion mixing superimposed forced shear mixing on the market. The mixing principle is: the mixing equipment barrel is selected to perform gravity diffusion mixing on the material while also allowing the built-in full-size blade to rotate independently, forcing shear mixing on the material at different speeds in the same direction. The internal spiral belt continuously cuts and stirring the added trace elements, so that it and the main powder are fully dispersed, and the purpose of uniform mixing of trace elements is achieved. The mixing time is more than 50% shorter than the traditional mixing equipment, the effective loading rate is 85%, and the mixing uniformity is unprecedented.
Whether it is mixing coffee powder or other powder raw materials, dual-power mixing equipment is better than other mixing equipment in the industry of single gravity diffusion mixing and forced shear mixing, and is a dark horse in the mixing field.
