摘要:本文按照产品类型,对近年来国内企业申请的关于加热烟草芯材制备工艺和技术相关的专利进行了统计、分析、梳理归纳,重点从专利的角度对国内加热烟草芯材制备工艺和技术的研究进展进行了综述。分析表明,基于造纸法、稠浆法、辊压法、干法4种工艺进行加热烟草芯材制备的专利数量共52件,其中辊压法数量最多,造纸法、干法数量相近,稠浆法最少,烟草行业申请数量占92.3%。
Abstract:In this paper, according to the type of products, the patents applied by domestic enterprises in recent years on the process technology of heated tobacco core material preparation were counted, analyzed, sorted out and summarized, focusing on the research progress of domestic heated tobacco core material preparation process technology from the perspective of patents. The analysis indicated that the number of patents for the preparation of heated tobacco core material based on four processes including papermaking method, thick pulp method, roller pressing method and dry method, totaled 52 patents, among which the roller pressing method had the largest number, papermaking method and dry method had similar numbers, and thick pulp method had the smallest number, and the applications from the tobacco industry accounted for 92.3%.
