Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and more specifically, to a device for spraying chocolate onto wafers. Background Technology

[0002] Wafer biscuits are a type of dessert made primarily from wheat flour and starch, with the addition of emulsifiers, leavening agents, and other auxiliary materials. The process involves mixing the powder, pouring it into a container, and baking it to create a porous sheet or shape. Two or more layers of biscuits are then filled with sugar, fat, or other fillings between the sheets or in the shapes. To further enhance the flavor of wafer biscuits, a layer of chocolate is often coated on the outside. However, wafer biscuits have a rectangular structure, and a single-direction chocolate spraying device is not suitable for completely coating the wafer, affecting the quality of the coating and making it difficult to ensure the uniformity of the chocolate coating. Therefore, we have proposed a chocolate spraying device for wafer biscuits. Utility Model Content

Example 2

[0022] Based on Embodiment 1, as shown in Figures 1 to 5, the striking mechanism 2 includes a movable box 16 fixedly connected to the outside of the coating box 1 and a rotating rod 15 rotatably connected to the inner cavity of the coating box 1 via bearings. Multiple striking rods 22 are fixedly connected to the side of the rotating rod 15. The ends of two rotating rods 15 extend to the outside of the coating box 1 and are fixedly fitted with gears 23. A reciprocating lead screw 17 is rotatably connected to the inner cavity of the movable box 16 via bearings. A servo motor 20 is fixedly installed at the end of the movable box 16.

Example 3

[0023] Based on Embodiment 1 and Embodiment 2, as shown in Figures 1 to 5, a control panel 26 is fixedly installed on the outside of the coating box 1.

[0024] It should be noted that this utility model is a device for coating wafers with chocolate. In use, firstly, chocolate syrup is added to the inner cavity of the coating box 1. The chocolate syrup is heated using an electric heating element 27, ensuring the top of the syrup submerges the area between the two limiting sprockets 5 on the conveyor rack 7. Then, a reduction motor 24 is started, driving a drive shaft 3 and two drive sprockets 4 to rotate clockwise. Through the transmission of the drive sprockets 4, limiting sprockets 5, and chain 6, the conveyor rack 7 rotates clockwise. At this time, the wafer to be coated with chocolate is placed on the conveyor rack 7 for transport. Then, the diaphragm pump 9 is started to guide the chocolate syrup from the inner cavity of the coating box 1 through the guide hose 10, dispensing pipe 11, and discharge pipe 28 into the inner cavity of the dispensing box 12. The conical groove 14 on the conical box 13 sprays the chocolate syrup from the inner cavity of the dispensing box 12 out from four directions. The chocolate syrup sprayed from the four directions coats the top and four sides of the wafer biscuit. At the same time, the bottom of the wafer biscuit moves with the conveyor 7 to the chocolate syrup inside the coating box 1, thus achieving chocolate coating on the wafer biscuit. Finally, the conveyor 7 continues to transport the coated wafer biscuit. The servo motor 20 is started to drive the reciprocating screw 17 to rotate. Through the transmission between the reciprocating screw 17 and the moving seat 19, the moving seat 19 and the rack 21 move laterally back and forth. The meshing transmission between the rack 21 and the two gears 23 drives the rotating rod 15 and the striking rod 22 to rotate back and forth. The striking rod 22 strikes the bottom of the conveyor 7, causing the wafer biscuit being transported on the conveyor 7 to vibrate, so that the excess chocolate syrup on the wafer biscuit falls off, ensuring that the chocolate syrup on the wafer biscuit becomes uniform.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
