Step 1: Understanding the Concept:
Dairy plant layout and design involve planning the space required for various operations, including reception, processing, storage, and utility services.
Accurate estimation of space is vital for operational efficiency and safety.
Step 2: Detailed Explanation:
Let us evaluate each statement for its factual correctness:
Statement 1 (Incorrect): It claims that space requirement *cannot* be estimated based on storage vessels. In reality, this is precisely how space is estimated. If a plant uses vertical silos, the footprint is small but height is high. If it uses horizontal tanks, the floor area requirement is much larger. Designers calculate the diameter and length/height of vessels to determine the exact room dimensions. Therefore, this statement is not true.
Statement 2 (True): Layouts must adapt to the plot. A long, narrow plot might require a "U-shaped" or "L-shaped" flow, while a square plot might favor a "Straight-line" flow.
Statement 3 (True): Congestion is a major safety hazard in industrial settings. Narrow aisles and cramped machine placements lead to forklift accidents and operator errors.
Statement 4 (True): A dairy plant is more than just the processing hall. It must account for milk tankers (movement and parking), administrative buildings, and the Effluent Treatment Plant (ETP), which often requires a significant area.
Step 3: Final Answer:
Statement 1 is the incorrect (not true) statement.
