[0014] Preferably, the core density is 1.30-1.70 g / cm³.
[0015] The present invention also provides a method for preparing a multi-layer sugar-coated food, which specifically comprises the following steps: S1: Wash and cut the lemon and green plum, remove the core, add them to water with dried tangerine peel and sugar in appropriate proportions, boil them together, continue to simmer and crush them, and then grind them into a puree; S2: Wash the hawthorn, cut it into pieces, remove the core, dry it separately, mix it with the dried tangerine peel according to a certain proportion, and then grind it to obtain fruit powder; S3: Fruit puree and fruit powder are weighed in proportion and placed in a mixing pot for stirring. The obtained powder-pure mixture is formed into preformed cores by a granulator, and the cores are dried with low-temperature hot air to a moisture content of 5-20%; S4: The core is placed in a sugar coating pan and rotated at a low speed. A small amount of thin syrup mixture is intermittently sprayed on its surface while blowing with cold / hot air alternately. After each spraying, the core is rolled for a period of time and sprayed again. After repeating several times, the isolation layer is coated. The isolation layer is dried with low-temperature hot air until it is in a slightly sticky state that is not completely dry. S5: Sprinkle enough powdered sugar into the icing pan to allow it to adhere to the surface of the isolation layer and continuously roll it to achieve uniform coating. During the rolling process, spray a small amount of sugar mixture on the isolation layer and sprinkle more powdered sugar to increase the thickness of the powdered sugar layer. Repeat several times to complete the coating of the powdered sugar layer. Blow the powdered sugar layer with low-temperature hot air until it is fixed on the surface of the isolation layer. S6: Spray the preheated concentrated syrup mixture evenly, in small amounts, and multiple times on the surface of the powdered sugar layer in a fine mist form, supplemented by low-temperature hot air blowing.

[0019] Preferably, in step S4, the spraying of the dilute syrup mixture can be repeated 2-4 times, and the isolation layer is dried with low-temperature hot air at 30-50°C after coating.
[0020] Preferably, in step S5, the spraying of the sugar liquid mixture and the addition of powdered sugar can be repeated for at least 15 rounds, and after the powdered sugar layer is formed, it is blown with low-temperature hot air at 30-50°C.
[0021] Preferably, in step S6, the spraying of the concentrated syrup mixture and the subsequent tumbling can be repeated for 20-25 rounds, and the crispy layer is dried with low-temperature hot air at 30-50°C after being coated.
[0022] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The sugar coating has a multi-layer structure, which can effectively cover the core. The multiple drying processes during the coating process can effectively reduce the moisture in the core and prevent the core components from being released. Since the sugar coating has a low moisture content, it has a high crispness and can give the food a good crisp taste. 2. The core is made of sticky fruit puree mixed with fruit powder. After it is made, the temperature difference between the inside and outside is large. Drying it with low-temperature hot air can reduce its surface roughness and avoid affecting the effect of the isolation layer being too thick or too thin, which will cause the food to have a poor taste. 3. The coating of the powdered sugar layer is achieved by multiple rounds of "wet powder addition". The powdered sugar on the outer layer can also effectively adhere to the core, thereby increasing the thickness of the powdered sugar layer. At the same time, the low-temperature hot air blowing can further shape the powdered sugar layer and prevent the powdered sugar from disintegrating. 4. The crispy layer is coated with multiple rounds of spraying and rolling of a concentrated syrup mixture, resulting in a smoother surface without any noticeable bumps. 5. The size and amount of the core and multi-layer sugar coating are controlled within a reasonable range. They can be easily crushed or dissolved in the mouth without the need for the consumer to crush them significantly. They are not easy to stick to the teeth and are suitable for consumers of all ages. 6. The particle size of the fruit powder is moderate. When the core is melted, the eater can feel the fine particles, but there will be no obvious foreign body sensation, which enriches the flavor of the food. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Table 1 Component input table of multi-layer sugar-coated fruit pills
[0028] The preparation methods of the multi-layered sugar-coated fruit pills in Examples 1-3 above all adopt the following processing steps to produce the products: S1: Wash and cut the lemon and green plum, remove the core, add them to water with dried tangerine peel and sugar in appropriate proportions, boil them together, continue to simmer for 20-30 minutes, grind them, and then grind them into a puree; S2: Wash the hawthorn, cut it into pieces, remove the core, dry it with dried tangerine peel at 60-70° C. for 11-12 hours, mix them in proportion, and then grind them to obtain a fruit powder with a particle size of 60-120 mesh; S3: Fruit puree and fruit powder are weighed in proportion and placed in a mixing pot for stirring. The obtained puree mixture is formed into pre-formed fruit dan cores with a diameter of 4-8 mm by a granulator, and then dried with hot air at 40-50°C to a moisture content of 5-20%; S4: Place the fruit dan core in a preheated (approximately 30-35°C) sugar coating pan and rotate it at a low speed (10-15 rpm). Use a spray gun or manually to intermittently spray a small amount of thin syrup mixture on its surface. At the same time, use alternating cold and hot air (primarily cold air) to help the thin syrup mixture spread, penetrate, and initially dry. After each spraying, roll it for a while to allow the thin syrup mixture to be evenly distributed and partially dried, then spray it again. Repeat 2-4 times to complete the coating of the isolation layer. Dry the isolation layer with low-temperature hot air at 30-50°C until it is slightly sticky but not completely dry. S5: Sprinkle enough powdered sugar into the icing pan to allow it to adhere to the surface of the isolation layer and continuously roll it to achieve uniform coating. During the rolling process, spray a small amount of sugar mixture on the isolation layer and sprinkle more powdered sugar to increase the thickness of the powdered sugar layer. Repeat this process for at least 15 times to complete the coating of the powdered sugar layer. Blow the powdered sugar layer with low-temperature hot air at 30-50°C until it is fixed on the surface of the isolation layer. S6: appropriately increase the speed of the sugar coating pan (20-25 rpm), use a spray gun to spray the preheated (about 50-60 ° C) concentrated syrup mixture evenly, in small amounts, and multiple times on the surface of the powdered sugar layer in a fine mist, supplemented by blowing with low-temperature hot air at 40-50 ° C. After drying, roll it through the sugar coating pan to polish it, repeat 20-25 rounds to complete the coating of the crispy layer, and dry the crispy layer with low-temperature hot air at 30-40 ° C until the multi-layer sugar coating is completely solidified and hardened, thereby preparing the multi-layer sugar-coated fruit pills described in Examples 1-3.
