Choco Pie and Sandwich Cake Production Line Overview
A choco pie production line, also known as a sandwich cake production line, is designed for the continuous manufacturing of filled and sandwiched cake products. Using eggs and flour as primary raw materials, the line produces chocolate pies, strawberry pies, and similar snack cakes through a fully automated process that supports consistent structure, taste, and appearance.
Complete Processing Flow for Sandwich Cakes
The fully automatic sandwich cake production line integrates multiple processing stages into a synchronized workflow, reducing manual handling and improving production efficiency.
- Slurry mixing and depositing to form uniform cake batter portions
- Tunnel oven baking followed by controlled cooling
- Vertical stacking, cake turning, and horizontal stacking for accurate alignment
- Cream filling and sandwiching to form finished choco pie structures
- Final cooling and packing to support stable shelf life
Main Equipment Configuration
A standard choco pie production line consists of a slurry mixer, paper feeder, depositing and forming machine, tunnel oven, cooling conveyor, paper recycling unit, stacking machines, cake turnover machine, sandwiching machine for cream filling, and cooling equipment. For extended product varieties, a chocolate coating machine can be added to produce coated chocolate pies.
Automation Advantages in Industrial Production
With a high level of automation, sandwich cake production lines operate with stable performance and high output efficiency. Automated stacking, turning, and filling reduce labor dependence while improving product uniformity, making the line suitable for long-term continuous production.
