Composite filter rod with corncob particles

Abstract

The invention discloses a composite filter rod with corncob particles. The corncob particles are obtained by performing microwave expansion, grinding and pelleting, baking and modulating a corncob. The corncob particles are applied to a cigarette filter, the adding amount of the corncob particles is 15-50% of the total weight of the filter rod, and an obtained binary composite filter rod is applied to a cigarette. The actual application shows that ingredients in the cigarette smoke, such as tar, nicotine and phenol, can be effectively reduced. The composite filter rod with the corncob particles is convenient to operate, low in cost, and has a good application prospect.

Description

technical field

[0001] The invention belongs to the technical field of cigarette materials, and relates to a cigarette filter tip, in particular to a corn cob particle composite tip capable of reducing harmful components in cigarette smoke. Background technique

[0002] Corn is the main food crop in my country, and its total output and export volume both rank first in the world. The total annual output of corn in my country is about 150 million tons, and more than 20 million tons of corn cobs can be produced every year. According to reports, corncobs, like wood, belong to plant fiber raw materials, mainly composed of 35% to 40% hemicellulose, 32% to 36% cellulose, 17% to 20% lignin and 1.2% to 1.8% Composed of ash, and the corncob has uniform structure, suitable hardness, good toughness, strong water absorption, and is easy to process. In addition to being partially used as raw materials for furfural, xylitol and other products, a large part of corn cob is directly burned ...
