Embodiment Construction
[0024] The invention provides a method for reducing the standard deviation of the cigarette density to achieve the purpose of improving the consistency and uniformity of the cigarette density, reducing the reject rate and reducing waste.
[0025] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] A method for reducing the standard deviation of cigarette density provided by an embodiment of the present invention comprises the steps of:
[0027] S1: Silk drying process, determine a set of suitable parameters for the wall temperature of the silk drying machine, the temperature of the h...

The invention discloses a method for reducing the standard deviation of cigarette density, which comprises the following steps: 1) a shred drying process, determining a group of suitable dryer drum wall temperature, hot air temperature, hot air door opening degree, moisture discharge opening degree parameters, so as to reduce the standard deviation of cigarette density; 2) a on-site air separationstep for lowering the temperature of tobacco shred to 0 DEG C to 40 DEG C so as to rapidly shape the tobacco shreds; 3) determining a group of optimum ambient temperature and humidity values, and keeping the ambient temperature and humidity uniform in the process of storing tobacco shreds, so as to avoid the influence of the variation of ambient temperature and humidity on the physical indexes oftobacco shreds in the process of storing tobacco shreds; 4) a heat preservation step of tobacco shreds to ensure that temperature difference between 0 DEG C and 2 DEG C from the air in the shreds storage room to the cigarette set. The method can improve the uniformity and consistency of the cigarette density in a certain range, reduce the standard deviation of the cigarette density, so as to makethe cigarette meet the national standard, reduce the reject rate, save raw materials and reduce the consumption of auxiliary materials.
Description
technical field [0001] The invention relates to the technical field of cigarette production, in particular to a method for reducing the standard deviation of cigarette density. Background technique [0002] As we all know, under the condition of a certain volume filled with shredded tobacco, the density of cigarettes is linearly related to the weight of cigarettes. The weight of cigarettes directly affects the smoke indicators such as tar, nicotine, and CO of cigarettes, and then affects the intrinsic quality of cigarettes. The uniformity of cigarette density distribution can better reflect the inner quality of cigarettes. [0003] In the prior art, due to the influence of the production process, the controllability of the cigarette density is poor, and it is difficult to meet the national cigarette standard, resulting in a large amount of waste cigarettes, resulting in waste of raw materials and auxiliary materials. [0004] Therefore, how to provide a method for reducing ...
