Description

Technical Field

[0001] The present invention relates to the field of dairy products, and particularly to goat milk tablets. Background Art

[0002] Goat dairy products have attracted much attention for their unique flavor, easy digestion and absorption, promotion of cell growth, improvement of immunity and intelligence, etc. Goat milk tablets are a new type of snack in recent years and belong to milk-containing solid foods. They are deeply loved by consumers for their rich nutrition and unique taste. However, during the production and circulation of goat milk tablets, a large amount of dust is generated on the surface of the product or inside the package, affecting the consumption experience of consumers.

[0003] Patent application document CN114568532A discloses a preparation method of low-sticky milk tablets, which includes the following steps: a wet mixing step, including wet mixing whole milk powder and a first amount of granulated sugar, and then drying to obtain whole milk sweet powder; a dry mixing step, including dry mixing the whole milk sweet powder, a second amount of granulated sugar and additives; and a tabletting step, including tabletting the dry-mixed whole milk sweet powder to obtain the low-sticky milk tablets. The milk tablets obtained in this way avoid the problem of stickiness to the teeth, as well as large amounts of dust and sticking to the punch, and the weight fluctuation of the milk tablets is small, thus enabling stable continuous production. However, since this method uses both a wet mixing step and a dry mixing step, it requires multiple devices and increases the production cost.

[0004] Patent application document CN114568531A discloses a coated milk tablet and its preparation method, including: weighing the components of the milk tablet and mixing them evenly, and then pressing the milk tablet; and preparing a coating slurry, and coating the pressed milk tablet with the prepared coating slurry so that the milk tablet has corresponding colors and flavors. The milk tablets obtained in this way have a variety of colored appearances through coating, and the outer film coating corresponds to the content milk tablet in terms of taste, strengthening the taste and taste experience of the product and improving the product competitiveness. The film coating process can also prevent the phenomenon of slight dust on the surface of the milk tablets to a certain extent because the coating usually has a smooth surface. However, since this method uses a coating step, it requires additional equipment and increases the production cost. Summary of the Invention

[0005] [Technical Problems to be Solved]
