Description

Technical Field

[0001] The present invention relates to the technical field of food processing equipment, and in particular to a rotary thawing and baking integrated device for frozen cake embryos and a thawing and baking method thereof. Background Art

[0002] Pastry production is a crucial area in the food processing industry, with its production process crucially impacting product quality and taste. Frozen pastry dough, a common semi-finished product in pastry production, is crucial for the quality of the final product, particularly in terms of how it is thawed and baked.

[0003] Traditionally, thawing and baking are separate operations. The frozen dough is first thawed in a thawing machine, then transferred to a baking machine for baking. This separate operation requires separate heating and operation of the thawing and baking equipment, and energy is lost during the material transfer process, increasing energy consumption by 30%-40% throughout the entire production process.

[0004] During the process of transferring the dough from the thawing equipment to the baking equipment, the dough is exposed to the external environment and is easily contaminated by microorganisms carried by the air, tools, personnel, etc., affecting product quality and safety, and does not meet the strict hygiene and safety requirements of the modern food processing industry.

[0005] Split operation requires more production equipment and space, and the production process is cumbersome, which increases production time and reduces production efficiency, making it difficult to meet the needs of large-scale, continuous production.

[0006] Because thawing and baking are carried out in different equipment, the temperature and humidity connection between the two is not precise enough, resulting in uneven heating of the dough during the thawing process, which in turn affects the baking effect and makes it difficult to maintain stable and consistent color, taste and quality of the product.

[0007] Furthermore, extensive experiments have confirmed that humidity control during the thawing phase has a crucial impact on the quality of the dough. When humidity fluctuations exceed ±15% RH during the thawing phase, the natural cracking rate of the dough after baking increases dramatically. However, using appropriate equipment for precise humidity control during production can significantly reduce the natural cracking rate to <0.7% (B / T20977-2007, "General Rules for Pastry"), while achieving color uniformity of >95% (Lab color difference ΔE ≤ 2.5). In comparison, the average natural cracking rate of the dough after baking using traditional thawing methods is as high as 2.3%.

[0008] Therefore, a rotary thawing and baking integrated device for frozen cake embryos and a thawing and baking method thereof are proposed. Summary of the Invention
