Description

Technical Field

[0001] The utility model relates to the production of compressed biscuits, in particular to a material mixing device for the production of high-energy compressed biscuits. Background Art

[0002] High-energy compressed biscuits are made of wheat flour, sugar, oil, and dairy products as the main raw materials. They are mixed with cold powder, rolled, baked, cooled, crushed, and mixed. Other auxiliary materials such as dried fruits and meat floss can be added and compressed. Due to the characteristics of high-energy compressed biscuits, they are difficult to digest and are prone to constipation. Therefore, by adding an appropriate amount of lactic acid bacteria fermentation liquid to the raw materials of high-energy compressed biscuits and producing and eating them together, the problem of high-energy compressed biscuits being difficult to digest can be solved.

[0003] Compressed biscuits are prepared by first sieving the weighed raw and auxiliary materials, mixing and pressing them into biscuit blanks, and then putting the compressed biscuit blanks into an oven for baking at a temperature of 95-110°C, a residence time of 30-45 minutes, and a moisture content of no more than 3% to obtain finished biscuits; the finished biscuits are crushed to obtain puffed powder with a fineness requirement of 50-70 meshes, and lactic acid bacteria fermentation liquid is gradually added according to 20wt% of the weight of the puffed powder, mixed and then compressed to obtain finished compressed biscuits. In the production process, due to the characteristics of high-energy compressed biscuits, the raw and auxiliary materials are not fluffy and easy to stick. When using traditional stirring devices, the stirring position is horizontal and in the same plane, and it is impossible or difficult to stir the materials at the upper and lower ends, which is easy to cause unstable product quality due to uneven stirring.

[0004] Therefore, the research purpose of the utility model is to design a material mixing equipment for high-energy compressed biscuit production that can achieve comprehensive horizontal and vertical stirring of materials, improve the uniformity of material mixing, and is suitable for stirring and mixing heavy or easily sticky materials.
