ZLSIL™ & ZLCSIL™ Series:
Premium Food Grade Silica Solutions for the Global Food Industry
As global demand for high-quality, convenient food products continues to surge, powdered ingredients have become the core building blocks of modern food manufacturing. However, most fine powdered raw materials—due to their micro particle size, inherent viscosity, or high hygroscopicity—frequently suffer from poor flowability, caking, and agglomeration during storage, transportation, and production. These issues not only increase operational difficulties, compromise the accuracy of automated dosing, but also directly undermine the consistency and quality of final food products.
To address this widespread industry pain point, Zhongqi (Shandong) Silicon Materials Co., Ltd. has developed the ZLSIL™ precipitated silica and ZLCSIL™ fumed silica series: high-efficiency, cost-effective, and food-grade functional additives that deliver systematic solutions for the food industry. As core processing aids for powdered food ingredients, our products empower manufacturers to boost production efficiency, elevate product quality, and gain a competitive edge in the global market.
Our ZLSIL™ and ZLCSIL™ food grade silica series deliver tangible, bottom-line benefits for food manufacturers worldwide:
• Dramatically improves powder flowability and minimizes material adhesion, caking, and agglomeration
• Enables precision dosing in automated production systems, ensuring consistent batch-to-batch quality of end products
• Manufactured to premium food-grade standards, fully compliant with food additive regulations in all major global markets
• Enhances storage stability of raw materials, withstanding extreme temperature and humidity fluctuations during global transportation and warehousing
• Streamlines production processes, reduces equipment downtime and cleaning frequency, significantly boosts operational efficiency and cuts overall production costs
• Ultra-high purity formulation that does not alter the original color, flavor, or nutritional profile of food raw materials
In modern industrial food manufacturing, powdered raw materials such as spice blends, fruit powders, and edible salt are almost exclusively dosed via automated feeding systems. Accurate and consistent dosing is the cornerstone of stable food quality, while poor powder flowability directly causes uneven feeding, dosing deviations, and non-conforming end products.
ZLSIL™ precipitated silica and ZLCSIL™ fumed silica form a high-efficiency flow-assist layer on the surface of powder particles, increasing inter-particle spacing to fundamentally improve powder flow performance. Meanwhile, with their ultra-high adsorption capacity, they rapidly absorb free moisture and oil on the powder surface, significantly reducing material viscosity and eliminating common issues such as powder bridging and uneven feeding. Notably, ZLCSIL™ fumed silica features exceptional purity, ensuring no alteration to the original appearance of raw materials, making it ideal for food ingredients with strict visual requirements.
Spray drying is a core manufacturing process for a wide range of food ingredients, including plant powders, whey powder, egg powder, and coffee creamer. During production, material caking and wall build-up inside the spray drying tower are persistent challenges, requiring frequent downtime for cleaning. This not only drastically reduces production efficiency but also incurs high equipment maintenance costs.
Our solution: inject ZLSIL™ precipitated silica or ZLCSIL™ fumed silica into the spray drying tower separately from the raw material slurry. This method eliminates tower wall caking and build-up at the source, minimizes equipment downtime for cleaning, and removes the need for post-drying powder blending steps. It directly increases output per unit time, representing the most efficient application method for silica as a flow aid and anti-caking agent in spray drying processes.
Grinding processes are widely used in the production of spices, seasonings, low-melting point powdered foods, and more. These materials typically contain moisture and oil, which frequently cause equipment adhesion, material caking, and equipment blockage during grinding. This prevents manufacturers from producing free-flowing finished powders and severely disrupts continuous production.
ZLSIL™ specialty silica and ZLCSIL™ fumed silica act as high-performance grinding aids for food processing. They not only improve the flowability and reduce caking tendency of ground materials, but also instantly adsorb liquid components released during grinding, maintaining a clean internal equipment environment. This drastically reduces cleaning frequency, extends continuous production cycles, and delivers significant cost savings. Our products are compatible with all mainstream grinding equipment, including hammer mills and pin mills, and support flexible dosing methods: pre-mixing before grinding, in-line dosing during grinding, and post-blending after grinding.
Food ingredient manufacturers supply products worldwide, facing highly variable temperature and humidity conditions during long-distance transportation and long-term storage. Fluctuations in environmental conditions often lead to powder caking and agglomeration, which degrade product performance and increase processing difficulties for downstream customers.
Incorporating ZLSIL™ or ZLCSIL™ series products into raw material formulations effectively inhibits powder agglomeration and caking. Even in harsh high-temperature, high-humidity environments, the materials maintain stable flowability, enabling manufacturers to deliver consistent, high-quality products to customers across the globe.
Instant beverages, instant soup powders, and other powdered food products have become mainstream in the global consumer market. The core consumer demands for these products are excellent flowability, anti-caking performance, and cold water dispersibility. This is especially critical for powdered beverages in vending machines, which are constantly exposed to steam and high humidity, making them extremely prone to moisture absorption and caking, resulting in uneven dispensing.
ZLSIL™ precipitated silica and ZLCSIL™ fumed silica significantly improve the flowability, anti-caking performance, and cold water dispersibility of powdered food products. With their superior adsorption capacity, they maintain the powder in a loose, free-flowing state even under long-term exposure to steam and harsh humid environments, ensuring a consistent, hassle-free consumer experience.
