Embodiment 1

[0023] (1) Cut and crush the rice into uniform particles;

[0024] (2) According to weight percentage, mix 88% of the chopped rice with 4% cyclodextrin and 8% gelatin thoroughly;

[0025] (3) In the above mixture, add water at 83°C accounting for 10% of the total weight of the mixture, stir and mix for 24 minutes to obtain an expanded material, and pour it into the feeding port of the extruder;

[0026] (4) Under the conditions of an extrusion temperature of 120°C and a screw speed of 500r / min, extrude the puffed material into pellets and cool to room temperature to obtain the puffed filter element of the cigarette filter rod;

[0027] (5) According to the conventional method, using the puffed filter element and the conventional cellulose acetate tow as materials, prepare a binary or ternary composite filter rod.

Embodiment 2

[0029] (1) Cut and crush the corn into uniform particles;

[0030] (2) According to weight percentage, mix 65% chopped corn with 23% cyclodextrin and 12% gelatin thoroughly;

[0031] (3) In the above mixture, add water at 85°C accounting for 18% of the total weight of the mixture, stir and mix for 25 minutes to obtain an expanded material, and pour it into the feeding port of the extruder;

[0032] (4) Under the conditions of an extrusion temperature of 180°C and a screw speed of 240r / min, extrude the expanded material into a cylindrical shape with a diameter of 7.0mm, and cool it to room temperature to obtain an expanded filter element for a cigarette filter rod;

Abstract

The invention discloses a degradable type composite filter rod for cigarette and a preparation method thereof. The preparation method comprises the following steps: edible raw materials such as grain, tubers, pulses or starchy are cut and smashed into uniform particles; 65-90% of cut and smashed raw materials are fully mixed with 3-30% of cyclodextrin and 5-15% of gelatin; 80-90 DEG C water with a weight of 10-30% of the total weight of the mixture are added, and a puffed material is obtained after stirring and mixing for 20-30 min; the puffed material are extruded and formed to obtain a puffed filter of a cigarette; a composite filter rod for cigarette is obtained by using the puffed filter and convention cellulose acetate fibers. According to the invention, the degradable type composite filter rod allows a cigarette filter to be novel and variable in structure without changing the physical property and the smoking quality of a cigarette, and is safe, nontoxic and environment-friendly; the degradation time of the degradable type composite filter rod is shortened; the environmental pollution is reduced.

Description

Technical field [0001] The invention relates to a method for preparing cigarette auxiliary materials, in particular to a method for preparing a degradable composite filter rod for cigarettes. Background technique [0002] Currently, the filter rod material used in cigarettes is mainly acetate filter rod. In the presence of sunlight and water, cellulose acetate (referred to as "cellulose acetate") will be inactivated and produce water-soluble cellulose acetate, which can be biodegraded. However, this degradation process is slow and time-consuming. In addition, during the forming process of the cigarette filter rod, the mutual adhesion of plasticizers and the wrapping of the tipping paper during the rolling process will degrade the acetate fiber in the cigarette filter. More difficult. [0003] With the continuous increase in the production and sales of filter cigarettes, the environmental pollution problem of non-degradable ordinary filter rods has become increasingly prominent. ...
