The process described involves maintaining a consistent condition during and between batches of production, characteristic of a batch process.
Batch processes are executed in defined quantities or lots where the process starts, runs for a set time, and then stops or resets for the next batch. The fermentor's glycol jacket temperature must be carefully controlled throughout the batch to ensure product quality.
Continuous processes (A) run nonstop with steady-state conditions, typical in chemical refineries but not in batch fermentation.
Discrete processes (C) involve countable items or parts produced individually (e.g., manufacturing of assembled products).
Manual (B) refers to human-driven control rather than an automated process type.
Batch processing is common in brewing and food industries and is covered in GICSP’s ICS Fundamentals and Operations domain, which differentiates process types to tailor cybersecurity strategies for control systems.
