Add the solvent to Coffee Bean Mush during the extraction stage, before completing the heating reaction. After Caffeine has formed, remove the remaining Water and Alcohol in the Evaporator before moving the prepared concentrate to the Chem Finisher. Adding solvent after evaporation makes the mixture wet again and does not replace the earlier extraction step.
Use a Composition Spectrometer to check the actual mixture at each transition. The important sequence is preparation, extraction, concentration and packaging. A container becoming smaller does not prove that Caffeine formed, and a Finisher rejecting a wet container does not mean you should add more solvent to the final concentrate.
Keep the four stages in the right order
| Stage | What you are trying to accomplish | Solvent's role |
|---|---|---|
| Blending | Turn Coffee Beans into a liquid mixture | Measure the resulting mush before dosing |
| Extraction and heating | Form Caffeine from the prepared mixture | Add the chosen solvent for this stage |
| Evaporation | Remove volatile liquid and concentrate the product | Remove remaining Water and Alcohol |
| Finishing | Package the prepared Caffeine | Do not add solvent simply to make the input wetter |
The machines perform different jobs. A Blender does not complete every reaction merely because it creates a liquid. An Evaporator does not manufacture Caffeine that never formed. The Chem Finisher packages the active ingredient; it is not a substitute for extraction.
This separation makes the timing question easier. Solvent belongs where you are using it to support extraction. Once the desired ingredient exists and you are drying the mix, adding more solvent is a deliberate return to an earlier stage, not a normal last-minute finishing step.
Blend and measure before dosing solvent
Attach a suitable liquid container to the Blender and process the Coffee Beans. Inspect the result with the Composition Spectrometer. The useful number is the amount of Coffee Bean Mush in the actual batch, together with any unwanted materials.
Do not dose from the number of beans alone if the resulting mixture can be measured. The scanner lets you work with what the container actually holds. This is especially helpful when you are trying to repeat a process and compare one batch with another.
Leave room for measured additions. Pouring directly from a large supply bottle can make a small adjustment difficult to control. Graduated cylinders or droppers help keep the addition deliberate, and another scan shows the resulting composition.
Keep this preparation container distinct from an already evaporated batch. Two coffee-related containers can be at different stages, and using the wrong one can make a correct solvent instruction appear to fail.
Add the extraction solvent before completing the reaction
Alcohol is the documented solvent for the alcohol-based Caffeine extraction route. Read the current recipe conditions and measure the actual Coffee Bean Mush before choosing the addition. Extraction has its own conditions and ceiling rather than converting every ingredient automatically.
The broader lesson is that heat and solvent are conditions of extraction, not decorations added after the product is ready. Add the measured solvent, inspect the mixture, then heat within the conditions of the route you are following.
Do not combine separate recipe instructions into an invented hybrid. An alcohol-based method and a water-based method have different temperature conditions and extraction behavior. Pick the intended route, check the current recipe information, and confirm that Caffeine appears in the mixture.
If you have already heated a batch without the planned solvent, inspect its composition before deciding what to do next. The scanner can distinguish an incomplete extraction from a batch that already contains usable Caffeine. Repeating every step blindly risks adding dilution without addressing the actual condition.
Monitor Caffeine formation with the scanner
The Composition Spectrometer is the useful feedback tool during extraction. Check for the active Caffeine rather than judging success only from the mixture's name, color or temperature.
A container can reach a temperature without containing the correct ingredients. Likewise, it can contain solvent without having completed the intended reaction. The result you want to see is the ingredient that the Caffeine Pill recipe actually consumes.
Once Caffeine has formed, note what else remains. Water, Alcohol, Fat and Oils, Protein and other material are not all addressed by the same step. The presence of active ingredient does not mean the rest of the mixture is ready for packaging.
Avoid chasing a final purity target by changing several inputs at once. Measure a small treatment, rescan and identify its effect before moving on. This makes a failed batch easier to diagnose and a successful batch easier to repeat.
Treat unwanted material as a separate problem
Coffee mixtures can contain Fat and Oils. Lipobond Agent can help settle fat, while Acid treatment can be relevant to Protein and other unwanted material. These treatments have their own consequences for the mixture and should be measured rather than poured in until the container looks different.
Do not call every liquid in the container solvent. Alcohol can serve the extraction route, while another chemical can serve a cleanup reaction. Adding either one changes the composition and can leave material that must be dealt with before finishing.
If you use filtering for suitable larger contamination, inspect what remains afterward. A filter is not a universal remover of every dissolved substance. The scanner, rather than the fact that you performed a filtering action, tells you whether the stage addressed the intended material.
Keep chemistry filtering equipment separate from drinking-water processing when practical. Residue from a chemical mixture is an avoidable complication when you later expect the same container or pitcher to hold saleable water.
Evaporate after extraction, not instead of it
The Evaporator removes Water, Alcohol and Lipobond Agent from a container overnight. Its job in this workflow is reducing the volatile liquid around the active ingredient. It does not create the missing Caffeine if the extraction step never succeeded.
Load the source mixture, confirm usable power and allow the overnight cycle to run. A large amount of removable liquid can need more than one cycle. Check the source composition afterward rather than assuming one night always finishes every batch.
An empty distillate container does not prove failure. At zero Quality, the Evaporator can remove liquid without catching any in the receiver. For Caffeine Pills, the relevant material is the concentrate left in the original container.
Remove volatile liquid after extraction rather than adding it at finishing.
Do not pour recovered Alcohol back into that source merely because it is available. If your goal is a dry concentrate, that transfer adds back the substance you were removing. Save recovered solvent separately for an appropriate future use.
Keep solvent out of the final packaging decision
After evaporation, inspect the original source container. Confirm that it contains Caffeine and that the unwanted volatile liquid has been removed sufficiently for finishing. Then move that container to the Chem Finisher and select Caffeine Pill.
A Caffeine Pill consumes five mL of Caffeine. Compare that requirement with the amount of active ingredient measured by the scanner, not the total volume of the mixed contents. A large container with little active ingredient does not necessarily produce many pills.
The Chem Finisher can introduce impurity of its own, and Chemical Equipment Modules improve that part of the process. That is a different issue from residual solvent. Upgrading the Finisher is not a reason to skip drying, and more evaporation is not a replacement for a desired Finisher upgrade.
If the machine rejects the concentrate, identify its unmet condition before returning to the solvent bottle. A wet input calls for addressing wetness. A wrong selected product calls for selecting the right recipe. An insufficient active ingredient amount is another separate limitation.
Diagnose a batch that was evaporated too early
If you put Coffee Bean Mush into the Evaporator before confirming extraction, scan the residue. The smaller volume alone cannot tell you what formed. You may have concentrated an unfinished mixture rather than prepared a Caffeine concentrate.
Return to the recipe's requirements using the actual remaining composition. Do not assume that adding an arbitrary amount of Alcohol after the fact recreates the proportions the original batch would have had. Measure what remains before making another change.
This is the point where careful batch identification pays off. Keep a note of whether the container has been blended, extracted or dried. A short stage label is more useful than remembering that a jar has been through one of the machines already.
If you cannot establish what the container holds, the scanner is the next tool. More overnight waiting cannot resolve uncertainty about which active ingredient exists in the mix.
Diagnose a batch that became wet again
A dry concentrate becomes wet again when you add Water, Alcohol or another removable volatile. If that happens, do not interpret the Finisher's rejection as proof that it needs still more solvent. Inspect the source and remove the newly added liquid as appropriate.
Separate the reason for the addition from the result. If you deliberately returned to extraction because the active ingredient was missing, you are revisiting an earlier stage. If you added solvent only because you thought every machine needed a liquid-looking input, the addition did not address a supported requirement.
Check the composition again before packaging. This confirms that the corrected process retained the desired Caffeine and did not merely produce another smaller but unsuitable mixture.
Use a repeatable handoff between machines
Before leaving the Blender, identify the mush. Before leaving extraction, identify Caffeine. Before leaving the Evaporator, identify a sufficiently dry source concentrate. Before pressing Output on the Chem Finisher, select Caffeine Pill and check the available active ingredient.
That handoff is more reliable than memorizing a long sequence without looking at results. It also tells you where to stop when something differs from expectations. You can fix the first unmet condition rather than repeatedly consuming solvent and power across the whole chain.
For the timing question, keep one rule visible: add solvent for extraction, then remove it for finishing. The scanner determines whether your current container is still at the extraction stage or ready to move forward. Following the contents rather than the appearance of the container prevents the same solvent mistake from recurring.
