Equipment Inspection and Maintenance Q&A for Dairy Processing: Multi-turn Dialogue and Prompt Engineering

This category covers full production processes for liquid milk, yogurt, powdered milk, and dairy ingredients. Daily documentation includes raw milk

What Data for This Category Includes

This category covers full production processes for liquid milk, yogurt, powdered milk, and dairy ingredients. Daily documentation includes raw milk acceptance records, standardized batching sheets, pasteurization or UHT heat treatment logs, CIP cleaning records, filling operation records, and sample retention and microbial test reports. Data comes from raw milk testing equipment, production MES systems, homogenization and heat treatment equipment, online temperature and flow sensors, CIP systems, and LIMS laboratory management systems. Updates occur in real time for each milk tank and production batch. Fields include raw milk antibiotic and physicochemical indicators, heat treatment time and temperature parameters, and aseptic filling verification data, among others.

Constraints for Multi-turn Dialogue and Prompt Engineering

The real-time, batch-bound data characteristics of dairy processing impose specific constraints. Multi-turn dialogue must associate context tied to the target production batch to avoid mixing data across batches. High-frequency real-time temperature, flow, and CIP cleaning parameters must be quickly called during dialogue. Prompts must limit the range of fields called in a single session to prevent context overload. Structured data from raw milk acceptance and microbial test reports must be explicitly linked to equipment numbers or batch numbers in dialogue. Multi-turn dialogue must retain chatId to bind the current session’s batch context. This ensures each question matches historical data from the corresponding production stage. Emergency response needs for perishable raw materials require dialogue responses to match real-time updated CIP records. Prompts must preset standardized workflow steps for equipment inspection. This restricts responses to valid data from the current batch only.

Configuration Settings

This configuration is based on FastGPT v4.17.0.

Configuration ItemRecommended SettingRationale
chatIdBind to the current production batch numberEnsures multi-turn dialogue context is tied to production data for the target batch, avoiding cross-batch data confusion
messages context organizationSort historical dialogue by production stageEnsures logical clarity of multi-turn dialogue historical context, enabling quick matching of current questions
Context window length800–1200 charactersMatches the average length of single-batch production records, covers core parameters for key equipment inspection and maintenance, prevents context overload
variables bound fieldsRaw milk antibiotic indicators, heat treatment time and temperature, CIP verification resultsLimits the range of called data sources, only uses valid batch data associated with the current session
Response timeout600 secondsMatches the average response waiting time for dairy processing equipment inspection, avoids session interruption due to timeout
Number of retained historical dialogue entries20Covers typical dialogue rounds for single-batch production, avoids excessive historical data occupying context space
Answer format controlDisable Markdown syntaxAdapts to the quick reading needs of equipment maintenance personnel, avoids format interference
Session reuse settingKeep current session without creating new onesSupports continuous multi-turn equipment inspection questions, aligns with on-site continuous troubleshooting operational habits

Three Common Mistakes

  • Phenomenon: Dialogue results only display in the side popup, with no visible output in the main dialog box. Cause: Rules for direct output to the main dialog box are not configured, and only side preview mode is enabled.
  • Phenomenon: A separate independent session window is automatically created each time a question is submitted. Cause: chatId is not bound to maintain the current session, and the default setting for automatic session creation is enabled.
  • Phenomenon: Answer content automatically uses Markdown syntax for formatting. Cause: The default Markdown rendering switch is not turned off, and the plain text output format is not specified.

How to Verify Proper Configuration

  • An equipment inspection question for the current production batch is submitted. The main dialog box is checked for direct display of the answer result to confirm the output position configuration is correct.
  • 3 consecutive equipment maintenance questions for the same batch are submitted. All interactions are checked to confirm they occur within the same session window, verifying session binding and reuse configurations are effective.
  • The answer content is reviewed. The absence of Markdown-formatted headings, lists, or other elements is confirmed to verify the format control configuration is correct.
  • The variables bound fields are called. The answer is checked to confirm it only references production data from the current batch, verifying the data source binding configuration is effective.
