An AI sales agent's GYRoCOMPACT 60 spiral freezer, checked before it goes out

An AI sales agent sizes a Frigoscandia GYRoCOMPACT 60 spiral freezer for a food producer: the variant (60/2, 60/2B or 60/3), the number of tiers, the belt link height and product height, the belt mesh, the defrost method, the electrical supply, and the normal power and base load it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures in the public JBT brochure and returns a verdict, every reason and the figures it computed.

Scope: GYRoCOMPACT 60 spiral freezers in the 60/2, 60/2B and 60/3 variants: tiers, belt link height and product clearance, mesh, defrost, supply and stated power. See everything this validator covers

This validator models one GYRoCOMPACT 60 spiral freezer at a time, based on the public JBT brochure "Frigoscandia GYRoCOMPACT 60" (B 3221-EN 2403), not just the scenarios shown below.

  • Tiers — the brochure lists 16 to 48 tiers for the 60/2 and 16 to 42 tiers for the 60/3; the 60/2B is listed with no tier range of its own, so a 60/2B quote goes to a person to confirm the tier count.
  • Belt link height and product clearance — link heights of 65, 80, 100, 120 and 150 mm give 50, 65, 85, 105 and 135 mm of vertical clearance, and the product must fit within it.
  • Defrost — hot gas or potable water; water defrost needs water at 15 to 25 C and at least 1 bar (3 bar nominal).
  • Supply and stated power — three-phase 380 to 480 V or 575 V at 50 or 60 Hz; the normal power and base load the quote states must equal the brochure figures for the variant (28 and 31 kW for the 60/2, 14 and 16 kW for the 60/2B, 39 and 50 kW for the 60/3). A refrigerant other than R717 (ammonia) goes to a person.

Any GYRoCOMPACT 60 quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none are modeled), freezing capacity and product-specific freezing times, building and installation layout, and other JBT freezer models.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Tier limits that differ by variant (48 and 42)Only with care
The allowed tier range is different for each variant, so a rules-based CPQ needs a rule or table row per variant.		The variant and tier count arrive in one request and are compared with the limits for that variant on every call.
Product clearance that depends on the belt link heightOnly with workarounds
The clearance is a function of the chosen link height, so a lookup has to be maintained and compared with the product height.		The clearance is derived from the link height and compared with the product height on every call.
Water defrost limits that apply only to water defrostOnly with care
Temperature, pressure and potable-water rules apply only when water is the defrost medium, so each needs a condition.		The conditions are part of the model and are checked together with the other rules.
Stated power and base load that must match the variantOnly with care
The stated figures have to be compared with the variant's figures after every change of variant.		The stated figures are fields in the request, compared with the variant's figures on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent sizes a Frigoscandia GYRoCOMPACT 60 spiral freezer for a food producer: the variant (60/2, 60/2B or 60/3), the number of tiers, the belt link height and product height, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures in the public JBT brochure and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a GYRoCOMPACT 60 spiral freezer, variant 60/2, with 36 tiers, 100 mm belt link height and 70 mm high product. The supply is 500 V at 50 Hz and the refrigerant is R717 (ammonia). The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The defrost water is at 12 C; the brochure lists a minimum of 15 C and a maximum of 25 C. The defrost water pressure is 0.8 bar; the brochure lists a minimum of 1 bar (3 bar nominal). A supply of 500 V is not listed; the brochure lists three-phase 380 to 480 V and 575 V.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for water defrost limits that apply only to water defrost, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the defrost water temperature to 18 C, the defrost water pressure to 2.5 bar and the supply to 480 V.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    14.
