This new type of tobacco material, made by meticulously rolling, flattening, and shredding tobacco leaf stems, offers a range of benefits for both manufacturers and consumers. Join us as we delve into the intricate process of creating Cut Rolled Expanded Stems and explore the myriad of advantages they bring to the table. Introduction to Cut Rolled Expanded Stems Cut Rolled Expanded Stems (CRES) represent a significant innovation in the tobacco industry. These are tobacco leaf stems that have been meticulously cut, rolled, and expanded to create a new type of tobacco material. Cutting the Stems The journey of a tobacco leaf stem to becoming a CRES begins with cutting. The stems are carefully cut to a width of 0.1 to 0.2 mm, ensuring uniformity and consistency. Rolling the Stems Next, the cut stems are rolled. This process flattens the stems to a thickness of 1 to 2 mm, preparing them for the next stage of the process. How do you properly dry rolled expanded stems before cutting? The process of properly drying rolled expanded stems before cutting involves several steps. Moisturizing the Stems The first step is to moisturize the stems. This is done to give the stems the elasticity required for cutting and to minimize the formation of tobacco dust during the technological process. The moisture content should be between 40 to 60% by weight. This can be achieved by soaking the stems in water or by steaming them . Rolling the Stems After moisturizing, the stems are rolled to a thickness of 0.1 to 0.5 mm. This process prepares the stems for the expansion process . Expanding the Stems The rolled stems are then expanded. This is done by heating the stems under pressure in the presence of superheated steam at a pressure of 3 to 10 kg/cm2 (gage), preferably 4 to 8 kg/cm2 (gage), and at a temperature of 150. to 300. C., preferably 190. to 260. C., for 1 to 30 seconds, preferably 2 to 15 seconds . Drying the Stems After the expansion process, the stems need to be dried. This can be done by adjusting the moisture content to about 24 to 60 percent by weight. The drying process is important to prevent the stems from acquiring a smell of scorching or a dark color. If the temperature is below 150. C., the original smell of the unexpanded stems will remain unchanged and so the smoking taste will not be sufficiently improved . Cutting the Stems Once the stems are properly dried, they can be cut to the desired width. The cut stems are then ready to be used in the production of tobacco products . What are some common mistakes to avoid when cutting rolled expanded stems? Inaccurate cutting angle: Cutting at an incorrect angle can result in uneven cuts and negatively impact the quality of the final tobacco product . Uneven cutting width: Consistency in cutting width is crucial for maintaining uniformity in the tobacco blend. Uneven cutting width can lead to an inconsistent smoking experience . Excessive moisture content: If the moisture content of the stems is too high, they may agglomerate and not shred properly. It is essential to maintain the right moisture content throughout the process. Using dull cutting tools: Dull cutting tools can result in jagged cuts and damage the stems, affecting the quality of the final tobacco product . Insufficient drying time: Proper drying is essential to prevent the stems from acquiring a smell of scorching or a dark color. Insufficient drying time can negatively impact the quality of the cut stems . What are the different methods for cutting rolled expanded stems? There are several methods for cutting rolled expanded stems, each involving specific machinery and processes designed to ensure the highest quality and industry standards. Here are some of the key methods: Shredding Machine One common method involves using a shredding machine to cut the expanded stems to a width of 0.15 mm. This results in cut stems with an apparent density of 0.40 g/cm3 . Stem Cutting Machines Stem cutting machines are specifically designed to cut tobacco stems. Once the stems are cut, they are passed through rolling machines that apply pressure on the cut stems, rolling them into a cylindrical shape. This rolling process is crucial as it prepares the stems for the expansion process by creating more surface area for heat penetration . Heat Treatment Systems After the stems are cut and rolled, they are subjected to a heat treatment process. This is achieved using heat treatment systems, which expose the stems to high temperatures, causing them to expand. These systems are designed to apply uniform heat, ensuring that all stems are evenly expanded . Microwave Expansion In some cases, microwave expansion is used to cut heavily rolled stems. This process is consistent with the traditional pneumatically dried cut stem process. However, in the process of pressing the stem and cutting the stem, smaller processing parameters of pressing stem roller gap and cutting stem width are adopted . Each of these methods has its own advantages and is chosen based on the specific requirements of the tobacco product being produced. It’s important to note that the quality of the cut stems affects the quality of the tobacco product, so it’s essential to cut the stems properly to ensure that the tobacco product is of high quality . How are Cut Rolled Expanded Stems made? Cut Rolled Expanded Stems (CRES) are produced through a multi-step process that involves cutting, rolling, and expanding tobacco leaf stems. Here is a detailed breakdown of the process: Preparation: The process begins with the preparation of tobacco stems. These stems are separated from tobacco leaves by threshing in a customary way . Shredding: The stems are then shredded to a suitable dimension . Moisturizing: The shredded stems are pre-conditioned by adding water to a water content of 7 to 22% (W/W), preferably 10 to 18% (W/W) . Rolling: The moisturized stems are passed between two rolling surfaces to produce a flattened stem . The rolling process prepares the stems for the expansion process by creating more surface area for heat penetration . Expansion: The rolled stems are then expanded. This is done by heating the stems under pressure in the presence of superheated steam at a pressure of 3 to 10 kg/cm2 (gage), preferably 4 to 8 kg/cm2 (gage), and at a temperature of 150. to 300. C., preferably 190. to 260. C., for 1 to 30 seconds, preferably 2 to 15 seconds . Drying and Cutting: After the expansion process, the stems are dried and then cut to the desired width. The cut stems are then ready to be used in the production of tobacco products . Expanding the Stems The final step in the creation of CRES is expansion. The rolled stems are rapidly heated and soaked in water, causing them to expand. This results in a tobacco material that is lighter and more voluminous than traditional tobacco stems. Benefits for Manufacturers For manufacturers, CRES offer several advantages. They are lighter and more voluminous than traditional tobacco stems, which can reduce shipping and storage costs. Additionally, their uniform size and shape can improve the consistency of tobacco blends. Benefits for Consumers For consumers, CRES can enhance the smoking experience. Their uniform size and shape can result in a more even burn, while their lighter weight can produce a smoother smoke.
