Description

Technical Field

[0001] The utility model relates to an automatic material mixing and pressing device, in particular to a nutrition bar raw material mixing and forming device. Background Art

[0002] Nutrition bars are a very popular instant snack. The processing of nutrition bars requires a variety of raw materials such as soy protein powder, fiber powder, starch, etc. to be mixed in proportion. Some products also need to add some fruit and vegetable extracts or nutrients. In the processing of nutrition bars, the raw materials need to be screened to a certain particle size, and each part of the raw materials needs to be stirred and mixed evenly. The general steps are to put a variety of raw materials into a mixing bin, stir them evenly, extrude them into shape, and then cut them. In the existing nutrition bar production device, when the raw materials are stirred, the premixed powder needs to be directly poured into the mixing bin first, and then the premixed liquid needs to be directly poured into it for stirring.

[0003] For example, a Chinese utility model patent with authorization announcement number CN210382593U discloses a forming and cutting device for nutrition bars, including a mixing bin, an extrusion bin, a forming cylinder and a cutting and pushing mechanism; the raw materials in the mixing bin of the utility model are mixed and processed and then discharged into the extrusion bin under the drive of a first spiral conveying mechanism, and the raw materials are extruded into the forming bin to form long strips of semi-finished materials under the action of the first spiral conveying mechanism and the second spiral conveying mechanism at the outlet of the extrusion bin, and the cutting and pushing mechanism at the outlet periodically cuts a section of the long strip of semi-finished products into pieces of nutrition bars, and then pushes them to be transferred from the unloading port of the material plate to the conveyor belt in turn for the next step of processing. Although the utility model patent shapes and cuts the nutrition bars, the mixing bin of the utility model still has the following problems when mixing materials: if the material mixing time is short, some premixed powders directly contact a large area of ​​​​a large amount of liquid, while some powders cannot directly contact the liquid and can only be slowly contacted and mixed with the dough paste through the continuous rotation of the stirring paddle at the back, resulting in insufficient and uneven mixing; if the material mixing time is long, some materials cannot be stirred for a long time, otherwise it will affect the product quality, reduce production efficiency, and is not conducive to product quality and actual production.

[0004] At present, some nutrition bar production devices will spray the premixed liquid into the mixing bin in the form of a column to mix with the powder, but the contact point between the columnar fluid and the powder is fixed, and the liquid will soon accumulate at this position, resulting in poor mixing effect.
