Spices refer to natural plant materials that can be used to add flavor to food, giving it aromatic, spicy, and hot flavors. Spices are rich in volatile essential oils and plant alkaloids, which lose a significant amount of their active components during grinding; some spices, being roots, stems, and leaves of plants, are hard to grind; some spices are rich in fiber and high in oil content, making it difficult for traditional grinding equipment to produce fine powders.
To solve the above difficulties in spice powder manufacturing, Rushi empowers traditional powder processing with modern technology, independently developing ultra-fine grinding equipment that can grind spice powders to a mesh size of 80-120 or more. This successfully develops ultra-fine spice powder products while effectively reducing the loss of spice components and ensuring product quality.
Ultra-fine grinding technology uses mechanical or fluid dynamics methods, generally referring to the process of crushing particles larger than 3mm into micron-level or even nanometer-level fine powders.
Ultra-fine powder is the final product of ultra-fine grinding. There is currently no unified standard for the particle size limit of natural spice ultra-fine powder, and it can be determined based on the actual situation of natural plant grinding and processing.
Ultra-fine powder is currently mainly used in soft drink processing, fruit and vegetable processing, grain and oil processing, seasoning processing, frozen food processing, including popsicles, ice cream, and traditional Chinese medicine production.
Specifically for spices, ultra-fine grinding technology, as a new type of food processing technology, can finely grind traditional spices into excellent ultra-fine particles with uniform particle size and good dispersibility. This plays an important role in fully releasing the flavor of spices and improving product quality.
Currently, there are two commonly used ultra-fine grinding equipment on the market: liquid nitrogen ultra-fine grinders and universal dust-free ultra-fine grinders. The products produced by liquid nitrogen ultra-fine grinders tend to agglomerate severely after warming, and due to the use of liquid nitrogen, the production costs are high, which is hard to bear for some spice products. On the other hand, the universal dust-free ultra-fine grinder has lower costs but results in significant loss of active components in the final product and low yield, making it not very suitable for the production of ultra-fine spice powders.
Rushi's independently developed ultra-fine grinder has been modified and upgraded based on the two common types of equipment. It uses a closed-loop system where the airflow inside the grinder forms its own system and includes controllable ultra-low temperature equipment. The equipment frequently maintains a cold grinding state, solving the issues of high heat and high wind speed generated by the material friction due to high rotation speed during grinding. This significantly reduces the loss of active components, lowers dust hazards, and improves product yield.
Equipment controllable temperature can reach -25℃
Product material temperature tends to be between -5℃ and 5℃
Spice powder product mesh size: 80 mesh - 120 mesh
Fine and smooth product, without a granular feel, grind fineness is controllable
High retention of product active components, with volatile oil loss between 15%-20%, alkaloid content loss within 5%, and product yield of over 95%.
Rushi, established in 2019, focuses on the processing and manufacturing of high-quality spice powders. We believe that "good flavor comes from good raw materials," and we insist on using good raw materials and good technology to create excellent powders, providing safe, stable, and extremely cost-effective spice powder products.
Adhering to the principle of empowering traditional powder processing with technology, Rushi has established a fully intelligent spice powder production line, including five major crushing processes, eight powder processing steps, and dual steam sterilization technology. Throughout the process, Rushi uses self-developed patented grinding equipment combined with a patented closed-loop system, reducing the overall loss of active components to below 10%, increasing production yield to over 94%, and creatively solving technical difficulties in the traditional spice powder industry such as large flavor changes, unstable quality, and significant loss of active components.
Currently, Chengdu Rushi Spices Co., Ltd has established stable cooperative relationships with hundreds of well-known domestic and international companies. We will continue to promote the standardization and modernization of the spice powder industry, dedicated to creating delicious flavors with Rushi and using delicious flavors to create a better life.
