Description

Technical Field

[0001] The invention relates to the technical field of chocolate production, and in particular to a filling chocolate production and molding device and a production method. Background Art

[0002] With the improvement of living standards, people have more and more demands for snacks and higher requirements. Chocolate is a food that many people like. Chocolate is fragrant and delicious, sweet and delicious, and is loved by many children and adults. Chocolate also has the effect of relieving diarrhea and relieving stress.

[0003] In the prior art, chocolate with fillings that do not have special requirements for the shape is usually processed by first producing the filling and then pouring hot molten chocolate on the filling. When a special shape such as a spherical chocolate with fillings is required, a molding device is required, such as the fully automatic production line for punching shells and spherical shells mentioned in Chinese patent publication No. CN115152878B, which belongs to the technical field of food processing equipment. The production line includes a frame, a mold, a transmission component, a first heating component, a feeding component, a punching shell component, a spreading component, a second heating component, a mold clamping component, a freezing component and a demoulding component. The production line sends the fillings to the mold by the operation of the mold. The first heating component, the feeding component, the shell punching component, the material spreading component, the second heating component, the mold closing component, the freezing component and the demoulding component are distributed in the moving direction. The mold with the folding and mold closing function is used to produce spherical chocolate with fillings. The transmission component is installed on the frame and arranged along the length direction of the frame. The transmission component is used to transport the mold. The production line abandons the existing technology of generating hollow structures by shaking, and directly uses the shell punching component to shape the chocolate, making the shape of the chocolate more stable. At the same time, the filling is added through the material spreading component, making it more convenient to add the filling, making the process of the production line more stable and efficient. However, there are certain drawbacks when using the above-mentioned disclosed technology. When the mold is closed, the two groups of chocolate half shells cannot be bonded as described after the mold surfaces are fitted. This is because the contact surface of the chocolate half shells is highly consistent with the mold fitting surface, and there is a lack of extrusion force, resulting in poor bonding effect. The two groups of half shells can easily separate during the subsequent packaging process. Therefore, it is necessary to improve and optimize the production and molding equipment and production method of sandwich chocolate to solve the above-mentioned problems. Summary of the invention

The silicone ball 29 is squeezed and expanded by the compressed air, and the outer wall of the silicone ball 29 and the lower wall of the bottom bracket 28 are aligned with the lower shell molding cavity 23. The molding area of ​​the shell is formed between the inner walls of the cavity 23. The melted chocolate is drawn from the shell storage tank 2 by a feed pump and poured into the molding area through the first shell pouring pipe 31 and the first shell pouring port 30. After cooling, the air in the cavity 2901 of the silicone ball 29 is sucked away by a negative pressure pump, so that the silicone ball 29 loses its expansion state, and the outer wall of the silicone ball 29 is separated from the inner wall of the cooled shell and is tightly attached to the outer wall of the connecting rod 27. Then, the first electric telescopic rod 24 extends and retracts its shaft, driving the silicone ball 29 and the bottom bracket 28 to withdraw from the upper opening of the molded shell, completing the first shell pouring; S2, pouring of sandwich material, the sandwich material is heated and melted in the sandwich material storage tank 3.
