Step 1: Understanding the Concept:
The manufacturing of biscuits, like most baked goods, follows a logical sequence of operations from raw materials to the finished product. The task is to arrange the given steps in the correct chronological order.
Step 3: Detailed Explanation:
Let's trace the process flow:
1. The first step is to combine all the raw ingredients (flour, sugar, fat, water, etc.) to create a homogenous dough. This is (D) Mixing.
2. Once the dough is ready, it must be shaped into individual biscuit pieces. This can be done by sheeting and cutting, rotary moulding, or depositing. This is (B) Forming.
3. The formed dough pieces are then passed through an oven to remove moisture and develop the characteristic texture, color, and flavor. This is (C) Baking.
4. After baking, the biscuits are hot and fragile. They must be cooled down to ambient temperature to become firm and crisp before they can be packaged. This is (A) Cooling and packing.
Step 4: Final Answer:
The correct sequence of operations is Mixing \(\rightarrow\) Forming \(\rightarrow\) Baking \(\rightarrow\) Cooling and packing. This corresponds to the order (D), (B), (C), (A), which is option (A).
