21 Reasons Why E-Cigarettes Flavor Has A Pasty Burnt Taste

January 02, 2024

E-cigarettes have experienced many years of development, we have slowly built up a certain perception of the taste, the paste/scorch/odor problem is increasingly being concerned by customers or consumers, after analysis, paste/scorch/odor problems are generally caused by the following reasons:

1. Battery rod/microphone head output voltage is too high, in the case of smooth oil conduction, the heating wire and oil-absorbing cotton is burnt;
2. Battery discharge rate is too high, in the case of poor oil conduction, the heating wire and oil-absorbing cotton is burnt;
3. Insufficient standing time after oil filling, the smoke oil is not fully transferred to the heating wire and oil absorbing cotton, and the suction will scorch the heating wire and oil absorbing cotton;
4. Oil and power mismatch, smoking to the late, the first oil depletion, the battery is still electric, the heating wire and oil absorbing cotton was burnt;

5. High viscosity and fluidity of the oil is not good, causing the oil absorbing cotton oil conduction is not smooth, suction will be the heating wire and oil absorbing cotton is burnt;

6. Oil-absorbing cotton density or not fluffy enough, caused by the oil-absorbing cotton oil guide is not smooth, suction will be the heating wire and oil-absorbing cotton was burnt;
7. Small diameter or small number of oil inlet holes, causing the oil-conducting cotton is not smooth, suction will be the heating wire and oil-absorbing cotton is burnt;
8. High sugar/sweetener content in the oil, causing carbon buildup on the wicking cotton, resulting in a mushy draw;
9. The oil inlet hole is designed too high, when the amount of oil in the oil cup is less than 1/3, the suction cotton can't absorb the smoke oil, and the suction will burn the heating wire and the suction cotton;
10. The oil inlet hole and the oil absorbing cotton surplus is not reasonably designed, causing the oil absorbing cotton to guide the oil is not smooth, suction will be the heating wire and the oil absorbing cotton is burnt;
11. Improper storage of cigarette oil or shelf life, causing flavor variations;
12.Mixing two or more kinds of oils accidentally for various reasons, causing flavor variations;

13. Failure to wake up the oil before injection, causing the oil to be layered, resulting in a large difference in taste;

14.Atomizer structure design is used to glue, the heating device will glue evaporation, resulting in glue odor;
15. Insulating ring/silicone sleeve/seal ring surface with oil stains such as stripper, contact with smoke oil causing taste variation;
16. Iron Chromium Aluminum heating wire has a chemical reaction with the tobacco oil, causing a rusty taste in vaping;
17. Plastic/silicone/glass fiber tubes are too close to the heating wire, and the heating wire will be scorched when it works, resulting in a bad taste;
18. Structural design defects, condensate flow back into the absorbent cotton, resulting in suction odor;
19. The airway is not smooth, the condensate gathered less into more, gathered around the heating wire, suction fried oil, resulting in hot mouth and odor;
20. The density of the oil storage cotton, some of the ingredients within the tobacco oil locked, the original formula failed to fully release the tobacco oil and play out, resulting in off-flavors;
21. Improper process layout or operation, the PCBA or microphone is activated before oil injection to start the work of the heating wire and oil absorbing cotton burnt.
