Baking soda, also known as sodium bicarbonate, is a versatile powdery material widely used in food processing, chemical manufacturing, flue gas treatment, water treatment, and many other industrial applications. Although it is relatively free-flowing when dry, baking soda can become cohesive, dusty, and moisture-sensitive during conveying, storage, and dosing. As a result, selecting a reliable pneumatic conveying solution is essential to maintain product quality, prevent blockages, and ensure accurate transfer from storage silos to process equipment. Our customized baking soda pneumatic conveying systems are engineered to handle these challenges with precision, safety, and long-term operational stability.

Sodium bicarbonate has a relatively small particle size and low bulk density, which makes it prone to dust generation and air retention. In a pneumatic conveying line, these properties can cause particle agglomeration, saltation, or blockage if the gas velocity and conveying pressure are not properly matched. Moisture is another critical factor. When baking soda absorbs humidity, it can form lumps, stick to pipe walls, and cause discharge problems in silos, hoppers, rotary valves, and filter receivers. Therefore, a successful conveying system must account for ambient humidity, particle size distribution, bulk density, flowability, and the required conveying distance. Our engineers evaluate these factors before recommending a suitable pneumatic conveying system and determine the optimal air velocity, solid loading ratio, and pipeline layout for every project.

We design two main types of pneumatic conveying systems for baking soda: dilute-phase pressure conveying and dense-phase conveying. In dilute-phase systems, baking soda is suspended in a high-velocity air stream and transferred through pipelines using positive displacement blowers or Roots blowers. This method is suitable for short to medium distances and for applications requiring moderate throughput. Dense-phase conveying operates at lower velocity and higher pressure, using compressed air to push plugs or slugs of material along the pipeline. This approach reduces particle degradation, minimizes pipeline wear, and is ideal for longer distances or fragile, abrasive, or very fine powders. For many baking soda applications, dense-phase conveying is preferred because it maintains the crystal structure and reduces dust generation. However, the final choice depends on site layout, capacity, and material characteristics.

Each custom baking soda pneumatic conveying system includes key components such as storage silos, discharge hoppers, rotary airlock feeders, screw conveyors, pick-up boxes, conveying pipelines, receiver filters, and process control panels. We also integrate dehumidified air supply, desiccant dryers, and moisture-proof storage solutions when the site environment is humid or when the product must remain ultra-dry. The pipeline design uses smooth bends with large radius or specially lined elbows to reduce material buildup and erosion. Additionally, our systems can be equipped with vibration aids, fluidizing pads, level sensors, and pressure transmitters to ensure continuous discharge and reliable operation. All contact parts are available in stainless steel or carbon steel with food-grade surface treatment, depending on the application. This modular approach makes it possible to adapt every system to existing plant layouts, production capacity, and future expansion.

Dust explosion safety is important in any pneumatic conveying system. Although baking soda is non-flammable, fine dust clouds can create explosive atmospheres if allowed to accumulate. Our systems include explosion venting, flame isolation, grounding, and static electricity prevention to keep dust emissions within limits. We offer nitrogen inerting and automatic interlocking. These safety features protect personnel and equipment while meeting international standards.
