7. Cooling and Slicing
Once baked, bread must cool before slicing and packaging.
Cooling Process
Cooling mats or conveyors are utilized to allow bread to cool evenly, which prevents steam buildup and sogginess. Proper cooling is vital as slicing warm bread can lead to gummy textures.
Slicing Techniques
Automated slicing machines ensure uniform slices, which is vital for packaging and presentation.
8. Packaging and Distribution
The final step in the bread-making process is packaging and distribution, ensuring the bread remains fresh until it reaches consumers.
Packaging Methods
Modern factories often use:
- Plastic Bags: Common for preserving freshness, offering visibility of the product.
- Paper Wrappers: A traditional choice, often selected for artisan breads.
Automated packaging equipment completes this process, ensuring efficiency and speed.
Distribution Techniques
Once packaged, products are ready for distribution through various channels such as grocery stores, restaurants, and bakeries. Logistics play a crucial role in maintaining the freshness of the bread during transportation.
