Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cake production, and in particular to a Bobo milk tea cake making method and cake coring equipment. Background Art
[0002] Bobo Milk Tea Cake is an innovative product that combines Bobo milk tea with cake. Its main components are cake base, milk tea flavored cream and milk tea Bobo.
[0003] The structure of Bobo milk tea cake is: add milk tea flavored cream into the cake base with grooves on the top, and decorate it with milk tea Bobo. When carrying out industrial production, the following issues need to be considered: 1. As a sealed packaged product, how to prevent the cream from sticking to the packaging bag after adding; 2. How to prevent the cream from changing its shape significantly during transportation, and the Bobo will not fall out; 3. How to ensure that the part of the cake that contacts the cream will not become soggy due to long-term immersion; 4. How to industrially and continuously produce cake bases with grooves.
[0004] There are two solutions to the fourth point. One is to inject cake slurry into a cake mold with a top post and bake it. Although this method can directly shape the cake, the moisture and heat of the cake in contact with the top post are unevenly distributed after forming, which will make the middle part softer and deformed, and the taste will also deteriorate. The other method is to dig out the middle part of the top after producing the cake embryo. This method is generally done manually, which is inefficient and the shape of the dug-out part will lose a lot of utilization value because it becomes broken, resulting in a certain amount of waste.
