Application Cases Of Centrifugal Spray Drying Equipment

The following are some application cases of centrifugal spray drying equipment:

Chemical Industry Field
Drying of Lignosulfonates: Lignosulfonates are products obtained by sulfonation modification of papermaking industrial waste, including calcium lignosulfonate and sodium lignosulfonate. The centrifugal spray dryer can atomize the lignosulfonate feed liquid, fully contact it with hot air, complete the dehydration and drying in a short time, and obtain a powdery product. This equipment has strong adaptability to high-concentration and high-viscosity lignosulfonate feed liquids, and the products have good uniformity, fluidity and solubility.
Production of Chemical Fiber Grade Titanium Dioxide: In the chemical fiber industry, there are high requirements for the quality and performance of titanium dioxide. The ultra-high-speed centrifugal spray dryer, through measures such as optimizing the atomizer design and improving the drying process parameters, can produce chemical fiber grade titanium dioxide with uniform particle size distribution, good dispersibility and high purity, meeting the demand for high-quality raw materials in chemical fiber production, and can improve the extinction, whiteness and mechanical properties of chemical fiber products.

Food Industry Field
For example, in the production of fat-rich milk powder, casein, cocoa milk powder, substitute milk powder, pig blood powder, egg white (yolk), etc. Taking the production of fat-rich milk powder as an example, the centrifugal spray drying equipment can atomize the milk feed liquid containing fat, protein, minerals and other components, contact it with hot air, and quickly dry it into milk powder particles. The products have good solubility and fluidity, can retain the nutritional components in milk, and meet the requirements of consumers for the quality of milk powder.

Pharmaceutical Industry Field
In biopharmacy, the centrifugal spray dryer can be used to prepare concentrated Bacillus subtilis BSD – 2 bacterial powder. By adding a certain proportion of β – cyclodextrin as a filler in the fermentation liquid and controlling process conditions such as the inlet temperature, feed liquid temperature, hot air volume and feed flow rate, the spray powder collection rate and bacterial survival rate can reach certain indexes, providing a feasible method for the development of new dosage forms of biological pesticides.

Environmental Protection Field
In the coking desulfurization process, a company uses centrifugal spray drying technology to dry and dehydrate the elemental sulfur and by-salts in the desulfurization liquid together, converting them into solid substances, which can be used as raw materials for sulfuric acid production. This not only solves the environmental problems existing in the treatment process of sulfur foam and by-salts, but also realizes the recycling of waste.

New Energy Field
A company has launched a new type of centrifugal airflow multi-purpose spray dryer, which is widely used in the field of new energy materials. For example, in the production of lithium battery materials such as lithium iron phosphate and lithium iron manganese phosphate, through the unique design of the centrifugal airflow multi-purpose atomization system, the equipment can produce powders with uniform particle size and extremely fine particles, significantly improving the charge and discharge efficiency of the battery. At the same time, the advanced control system equipped with the equipment can accurately regulate the key parameters in the drying process, ensuring the stable and consistent quality of the materials and providing a guarantee for the consistency and reliability of the battery. In addition, the equipment can also meet the production requirements of emerging fields such as sodium ion battery materials and solid-state battery materials.
