And (3) comparison test:
the invention adopts a mode of independently combining polyethylene glycol, acetate fiber tows, a smoke agent and a solid spice. The aim is that when the polyethylene glycol, the smoke agent and the solid spice are mixed according to a certain mass proportion, the mixture cannot form a filter stick structure, namely, cannot be formed, and naturally cannot judge the forming effect, the smoke increment and the aroma increment.
Namely comparative example 1: when 150g of polyethylene glycol (molecular weight 4000) is placed in a water bath kettle at 70 ℃ and heated to be dissolved, 250g of a smoke agent (propylene glycol: glycerol = 2) is added and mixed uniformly, 300g of solid perfume is added and stirred uniformly to form a mixed system, and then the mixed system is injected into an acetate tow to manufacture a filter stick, so that the filter stick cannot be formed. Examples of shaping are based on other mass ratios of the mixed system, such as:
example 1
500g of polyethylene glycol (molecular weight 4000) is placed in a water bath kettle at 70 ℃ and heated to be dissolved, then 200g of smoke agent (propylene glycol: glycerol = 2). And then the mixed system is injected into the acetate fiber tow to prepare the fuming gel filter stick.
Example 2
400g of polyethylene glycol (molecular weight of 5000) is placed in a water bath kettle at 75 ℃ and heated to be dissolved, then 400g of smoke agent (propylene glycol: glycerol = 4). And then the mixed system is injected into the acetate fiber tow to prepare the fuming gel filter stick.
Example 3
300g of polyethylene glycol (molecular weight of 6000) is placed in a water bath kettle at 78 ℃ to be heated and dissolved, then 500g of smoke agent (propylene glycol: glycerol = 2). And then the mixed system is injected into the acetate fiber tow to prepare the fuming gel filter stick.
Comparative example 2
500g of polyethylene glycol (molecular weight 4000) is placed in a water bath kettle at 70 ℃ and heated to be dissolved, then 150g of smoke agent (propylene glycol: glycerol = 2). And then injecting the mixed system into a cellulose acetate tow to prepare the fuming gel filter stick.
Comparative example 3
450g of polyethylene glycol (molecular weight 4000) is placed in a water bath kettle at 70 ℃ and heated to be dissolved, 450g of smoke agent (propylene glycol: glycerol = 2). And then the mixed system is injected into the acetate fiber tow to prepare the fuming gel filter stick.
Comparative example 4
500g of polyethylene glycol (molecular weight 4000) is placed in a water bath kettle at 70 ℃ and heated to be dissolved, then 200g of smoke agent (propylene glycol: glycerol = 2). And then injecting the mixed system into a cellulose acetate tow to prepare the fuming gel filter stick.
All the above examples were reviewed by a 10-person professional review panel, and the following review forms were summarized.
Evaluation form of embodiment
| Example of the embodiment | Effect of formation | Increase in smoke | Increase in fragrance |
| Example 1 | Good taste | Rich | The dried orange peel has obvious characteristic fragrance and improved taste |
| Example 2 | Good taste | Sufficient (sufficient) | The characteristic fragrance of cocoa is obvious and the fragrance is improved |
| |
Good taste | Is full | Rich tobacco fragrance of flue-cured tobacco |
| Comparative example 1 | Can not be molded | Can not evaluate the smoking | Can not evaluate the smoking |
| Comparative example 2 | Good taste | Deficiency of | The characteristic fragrance of the dried orange peel is obvious |
| Comparative example 3 | Good taste | Sufficient for | The characteristic fragrance of the dried orange peel is not obvious |
| Comparative example 4 | Good taste | Rich | Pericarpium Citri Reticulatae with no obvious fragrance |
Based on the evaluation of the above embodiment, although there is a better embodiment, the ratio does not clearly show the clear characteristic parameters of the forming structure, so the invention adopts a split independent structure to ensure the practicability and effect of the structure.
According to actual detection, the mass ratio of the polyethylene glycol, the smoke agent and the solid spice is 20-50:20-50:20-60 parts of; the mass ratio of the propylene glycol to the glycerol in the smoke agent is 2-5:5-8; the molecular weight of the polyethylene glycol is 3000-6000. The present invention cannot perform all parameter tests within the above-mentioned interval. Only the following test parameters were used. The setting of the parameters can realize the effects of stable forming, more than full smoke increasing level and rich fragrance increasing.
