The included angle of the thrown particles is small, the particles are almost thrown off right above the crackling of the product, the particles are not easily combined at the bottom and below the product, and the appearance effect of the product is poor.
Example 8
The embodiment provides a frozen drink with chocolate-coated particles and a preparation method thereof, the frozen drink with chocolate-coated particles comprises a frozen drink cake body and a frozen drink bonding layer arranged on the surface of the frozen drink cake body, wherein the formula of the frozen drink cake body is the same as that of the embodiment 4; the formula of the bonding layer of the frozen drink is the same as that of example 4; the recipe of the chocolate crackling is the same as that in example 4;
the preparation method of the chocolate-coated particle frozen drink is the same as the preparation method of the chocolate-coated particle frozen drink in the embodiment 4, and the only difference is that: the grain throwing direction of the grain throwing coating is obliquely above the chocolate crackling, the acute included angle between the grain throwing coating and the chocolate crackling is 85 degrees, and the grain throwing included angle is large, so that the effect of crackling combined particles on the uppermost part of the product is poor, and the appearance quality of the product is poor.
Example 9
The embodiment provides a frozen drink with chocolate-coated particles and a preparation method thereof, the frozen drink with chocolate-coated particles comprises a frozen drink cake body and a frozen drink bonding layer arranged on the surface of the frozen drink cake body, wherein the formula of the frozen drink cake body is the same as that of the embodiment 4; the formula of the bonding layer of the frozen drink is the same as that of example 4; the recipe of the chocolate crackling is the same as that in example 4;
the preparation method of the chocolate-coated particle frozen drink is the same as the preparation method of the chocolate-coated particle frozen drink in the embodiment 4, and the only difference is that: in the comparative example, the surface temperature of the frozen drink is maintained at-6 ℃, and the ice cream cake body is easy to melt when chocolate coating is carried out due to the high temperature of the outer layer of the ice cream cake body, so that the chocolate coating liquid is continuously viscous.
Example 10
The embodiment provides a frozen drink with chocolate-coated particles and a preparation method thereof, the frozen drink with chocolate-coated particles comprises a frozen drink cake body and a frozen drink bonding layer arranged on the surface of the frozen drink cake body, wherein the formula of the frozen drink cake body is the same as that of the embodiment 4; the formula of the bonding layer of the frozen drink is the same as that of example 4; the recipe of the chocolate crackling is the same as that in example 4;
the preparation method of the chocolate-coated particle frozen drink is the same as the preparation method of the chocolate-coated particle frozen drink in the embodiment 4, and the only difference is that: in the comparative example, the surface temperature of the frozen drink is maintained at-20 ℃, and the temperature of the outer layer of the ice cream cake body is low, so that the temperature difference between the ice cream cake body and the chocolate crackling is large when chocolate is coated, the drying time of the chocolate crackling is shortened, and the subsequent particle coating process effect is influenced. In addition, the temperature of the outer layer of the ice cream cake body is low, the required refrigerating capacity is large, and the manufacturing cost is increased.
Comparative example 1
