Ingredients:
The raw materials include rubber powder (also a special type of wood powder), wood powder, spice pigments, etc.
The main component of the fragrance is wood powder, which is required to have no odor, that is, no unpleasant smell; The fineness is generally around 80-100 mesh, with no other special requirements. Recently, other plant powders have also been used, such as various crops such as orange stalks and grass powder. Or a combination of them.
Traditional rubber powder is elm bark powder, which is used to bond wood powder together, making the resulting fragrant knots elastic and not easily broken. The quality of elm bark powder is also different. The core bark in the bark mainly works, while the old bark on the outside does not work. The common name for those without old skin is white elm powder, and for those with old skin, it is red elm powder. The ratio of elm bark powder to wood powder is approximately 1:1-1:2 by weight. Due to the limited quantity of elm bark powder, various binders are also added in modern times.
Spices can be various natural spices, such as sandalwood, agarwood, etc. There can also be various spices found in traditional Chinese medicine, such as star anise and fennel. In recent years, many kinds of essence are used most. Obviously, the cost difference of different spices is quite significant. Most of the essence in the market are used. The use of essence can produce a variety of flavor that people like, which is no less than or better than natural flavor and Chinese herbal medicine flavor. Because some essence is extracted from natural flavor. But when it comes to the benefits for the human body, compared to natural spices and herbal spices, they are probably far behind.
In addition to the above ingredients, nowadays fragrance making generally requires adding pigments to create colors that people like. There are no special requirements for pigments. Another reason is the addition of trace amounts of substances by producers in order to improve quality or reduce costs. These are all secrets from the producers, each with their own tricks. At the same time, precisely because they are confidential, it is unknown to what extent these tricks are scientific and fair.
The last thing we need is water. Strictly speaking, water cannot be considered as raw material, as it only plays a role in the fragrance making process. Only after drying and drying to remove moisture can the fragrance be considered as finished product. But in the process of making incense, water is indispensable. In good raw materials, the weight of water accounts for about 40% -60%, which varies greatly depending on the variety of fragrance, the fragrance making process, and the equipment used.
For many years, due to their respective interests, the fragrance industry has been relatively closed off, and each producer has kept their technology confidential. Therefore, the overall development of the fragrance industry has been hindered.
The process of making incense sticks:
1、 Stir. Put various raw materials and water in a certain proportion into the mixer. The structure of a general mixer is very simple, with blade claws inside the mixing drum. Through the rolling of the blade claws, the mixed raw materials are evenly mixed. The mixing of ingredients is crucial in the entire fragrance making process, which requires experience. First, dry the ingredients and mix them evenly, with appropriate proportions and moisture.
2、 Extrusion molding. This process is completed by a fragrance making machine. The current fragrance making machine is mainly composed of hydraulic system extrusion chute and mold. Put the mixed material into the material trough and press it downwards by the hydraulic system. The compressed material is extruded from the mold hole and becomes the desired shape. Nowadays, fully automatic incense machines with dual material slots are used, which can save the time waiting for the incense machine to be loaded. A mold is a strip steel plate with many holes arranged in rows, including one, two, or more rows. The most commonly used is the second row of holes. So the extruded incense sticks are also arranged in rows.
3、 Pick up the incense and tidy up. We need to use Xiangluo here. Xiangluo is usually made of wooden strips to form a rectangular frame, with plastic mesh stretched on top. Used to store incense sticks for easy drying and drying.
The molded incense sticks need to be dehydrated and dried before they can be packaged and sold. It is generally divided into two types: natural drying and oven drying. There are also heat pump dryers available now.
Drying rooms are mainly used by large fragrance factories. The commonly used one is the drying room. In a well insulated room, use methods such as a heated kang, heater, and stove to heat it up. Place the molded incense sticks on the incense rack in the drying room. The drying room has ventilation equipment to facilitate the removal of moisture. The temperature inside the room is about 40 degrees Celsius, and it usually takes a few hours to produce fragrance. First in, first out, cyclical production. Another option is to use a heat pump for drying, which usually costs tens of thousands of yuan per set of equipment, but is relatively labor-saving.
Small fragrance factories often use natural drying. It can be dried on the site or indoors in the shade. It depends on the specific situation. Drying out quickly, but easily deformed. When drying, the upper part of the incense stick loses moisture quickly and shrinks quickly, causing the ends of the stick to tilt upwards. After the upper part is dried and shaped, the shrinkage force of the lower part is not enough to pull the already shaped upper part, and in the end, the fragrance stick will bend. During the drying process, you can sprinkle some water on top of the incense sticks to control and reduce deformation. Yin dry is to place fragrant Luo on an indoor incense rack for natural ventilation. Long drying time and small deformation.
If the deformation is significant, the incense sticks can be removed in rows and stacked horizontally and vertically in a staggered manner. After a period of time, it can have a corrective effect.
The dried incense sticks can be packaged. There are also various types of packaging, usually relatively simple. It's just that the incense sticks tied up into bundles are a bit particular, here's a simple introduction. The cross-section of a typical incense stick is a symmetrical hexagon, and not a regular hexagon. The regular hexagon reduces two symmetrical sides. But this is not clearly defined, perhaps it's just a habit! So you can definitely tie it into a regular hexagon, or reduce the four sides, etc. After packaging, it is a complete product.
