Question

Process scheduling helps in finding

• A. The number of persons to be employed
• B. Locating the equipment in a section
• C. Peak hourly handling rate in each operation
• D. Area of the each section

Hint:

Dairy Process Engineering: PROCESS SCHEDULING determines the PEAK HOURLY HANDLING RATE in each section to correctly size equipment and utilities.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Operations research and process scheduling in dairy plants: process scheduling maps the temporal sequence and duration of plant operations (milk reception, standardization, pasteurization, packaging, CIP), calculating the peak hourly throughput handling rate ($L/ ext{h}$ or $ ext{kg/h}$) required to size processing equipment and utility boilers.
Key Formula or Approach:
\[ \mathbf{Process \text{ } Scheduling} \implies \text{Time-Volume Bar Chart} \longrightarrow \mathbf{\text{Identifies Peak Hourly Handling Rate } (L/\text{h}) \& Utility Loads} \]

Step 2: Detailed Explanation:
In dairy plant design, capacity sizing, and production planning:
- Process Scheduling is the systematic time-motion planning and graphical synchronization (Gantt charts sequence diagrams) of all sequential dairy operations over a 24-hour manufacturing cycle:
1. It maps when milk reception, raw milk cooling, pasteurization, cheese making, butter churning, packaging, and CIP sanitation occur across equipment units.
2. Primary Engineering Outcome (C): It identifies the Peak hourly handling rate in each operation (e.g., maximum milk flow rate requiring pasteurization at 09:00 AM or maximum peak steam demand during simultaneous pasteurization and evaporation).
3. Equipment capacities (pasteurizers, homogenizers, pumps) and utility sizes (boilers, refrigeration compressors) are sized specifically to match this peak hourly load.

Step 3: Final Answer:
Therefore, process scheduling helps in finding Peak hourly handling rate in each operation, corresponding to option (C).
