In the production lines of industries such as chemical, food, and environmental protection, baking soda has become the core raw material for deacidification agents, leavening agents, and adsorption materials due to its weak alkalinity, adsorption properties, and stability. However, the moisture content of baking soda on a wet basis can reach 25% to 35%, and traditional drying methods can easily lead to particle aggregation and loss of activity. The baking soda pulse airflow dryer utilizes the "instantaneous high temperature, strong turbulence dispersion" technology to compress the baking soda drying time to 3-5 seconds, reducing the moisture content to below 0.5% and maintaining a particle activity retention rate of over 95%. This article focuses on four major application areas to reveal how this "dry black technology" is reshaping the value of the baking soda industry.

　　1、 Food grade baking soda: the "quality guardian" of leavening agents and preservatives

In the production of baked goods and beverage additives, the purity and particle uniformity of baking soda directly affect the taste and safety of the product. The pulse airflow dryer achieves quality upgrades through the following technological breakthroughs:

1. Low temperature drying process: using hot air at 120-140 ℃ to avoid high-temperature decomposition (baking soda decomposition temperature>150 ℃), ensuring the retention of effective ingredients;

2. Classification and crushing system: Integrating a turbine pulverizer in the drying tube to refine particles to 20-50 μ m and improve swelling efficiency by 30%;

3. Aseptic design: The entire pipeline is made of 316L stainless steel material, combined with online ozone sterilization, to meet food grade GMP standards.

After being applied by a baking raw material enterprise, the dissolution rate of baking soda increased by 40%, and the error in swelling volume decreased from ± 15% to ± 5%.

　　2、 Industrial deacidification agent: the "green engine" for flue gas treatment

In the flue gas desulfurization and denitrification of coal-fired power plants and waste incineration plants, baking soda, as a dry deacidification agent, needs to meet the requirements of high specific surface area and rapid reaction characteristics. The pulse airflow dryer passes through:

1. Ultra fine crushing technology: Crush baking soda particles to D50=10 μ m, with a specific surface area of 5m2/g, and increase reaction efficiency by 2 times;

2. Anti sticking wall design: The inner wall of the pipeline is coated with PTFE coating to avoid material agglomeration caused by high humidity exhaust gas;

3. Precise measurement system: linked with PLC, real-time adjustment of feed quantity (deviation<0.5%) to ensure optimal use of deacidification agent.

After the use of a certain garbage incineration plant, the SO2 emission concentration decreased from 150mg/m3 to 35mg/m3, saving 1.8 million yuan in annual cost of deacidification agents.

　　3、 Environmentally friendly adsorbent materials: molecular catchers for VOCs treatment

In the treatment of chemical waste gas and VOCs in printing workshops, modified baking soda adsorbents need to have high porosity and regeneration ability. The pulse airflow dryer passes through:

1. Porking process: Inject water vapor during the drying process to form 0.1-1 μ m micropores in the particles, increasing the adsorption capacity by 50%;

2. Hot air circulation system: recovers exhaust waste heat (80-100 ℃) for pre drying, reducing energy consumption by 40%;

3. Explosion proof design: Using nitrogen protection and electrostatic grounding to ensure safe operation in flammable gas environments.

After being applied by a printing enterprise, the VOCs removal rate increased from 70% to 92%, and the adsorbent regeneration cycle was extended to 30 days.

The "cross-border" application of baking soda pulse airflow dryer is essentially a deep adaptation of material characteristics: avoiding thermal sensitive decomposition through instantaneous high temperature (3-5 seconds), breaking agglomeration through strong turbulence, and combining modular design to achieve multi scene switching in food, industry, and environmental protection. Data shows that this technology can reduce the energy consumption of baking soda drying by 60% and increase production efficiency by more than 10 times. Driven by the "dual carbon" target, this "dry black technology" is driving the transition of the baking soda industry from extensive processing to high-value utilization with millisecond precision. When baking soda particles trace a golden path in the pipeline, what we see is not only the evaporation of water, but also a synergistic evolution of green manufacturing and circular economy.
