[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 made by first sieving the weighed raw materials 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 mesh, 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 materials or mixed raw materials and auxiliary materials are easy to agglomerate, resulting in unstable product quality and in order to ensure the taste of the product, screening is required, but the problem of raw material agglomeration makes the screening effect and screening efficiency of traditional vibrating screening equipment poor.
