- quadruple effect evaporator is most commonly in use evaporators at the present time ⟨sugar manufacturing⟩
At the present time the quadruple effect, or four-cell evaporator, is most commonly in use
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage with the exact quote: 'At the present time the quadruple effect, or four-cell evaporator, is most commonly in use.' All elements of the claim—subject, predicate, and object—are explicitly supported without requiring outside knowledge or generalization.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself makes this assertion without naming a source). The stance is 'asserts' which matches the declarative statement in the passage. The sentiment is neutral, reflecting the objective tone of the technical description. The time qualifier correctly uses 'at the present time' as stated in the passage with null for valid_from and valid_to, which is appropriate since no specific dates are given. The context 'sugar manufacturing' is appropriate given the passage discusses sugar juice evaporation. The quote is verbatim and directly supports the claim.
although sextuple effects are not rare
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'although sextuple effects are not rare.' The quote matches the text exactly and is presented in the context of discussing multiple-effect evaporators in sugar manufacturing.
- qualifier_fidelity 0.90 pass — The quote is accurate and all qualifiers are faithful to the passage. The viewpoint, stance, and sentiment are correct. The time qualifier appropriately references 'at the present time' as stated in the passage. The context of sugar manufacturing is implicit in the passage. Minor deduction: the quote should ideally include surrounding context ('The ordinary practice is as follows: The quadruple effect, or four-cell evaporator, is most commonly in use, although sextuple effects are not rare') to fully capture the comparative framing, though the quoted fragment is still faithful.
it is sent to the evaporators for concentration
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'following which it is sent to the evaporators for concentration.' The passage explicitly confirms that juice is sent to the evaporators after the third filtration for concentration purposes.
- qualifier_fidelity 0.95 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (omniscient narrative voice describing the process). The stance 'asserts' matches the passage's definitive statement. Sentiment is neutral as appropriate for technical description. Time qualifiers are correctly null since the passage provides no temporal information. Context 'following third filtration' accurately reflects the passage's statement 'following which it is sent to the evaporators.' The quote is verbatim and directly supports the claim. Minor deduction (0.05) only for the quote being slightly truncated from the full clause 'following which it is sent to the evaporators for concentration,' though the quoted portion is accurate.
