Zhejiang Meibao Industrial Technology Co., Ltd. is one of the leading manufacturers and suppliers of high tower spray-dried laundry detergent powder in China. With abundant experience, we warmly welcome you to buy custom made high tower spray-dried laundry detergent powder from our factory. For price consultation, contact us.
Product Overview
High Tower Spray-Dried Detergent Powder is produced through a classic slurry preparation + spray drying process. The slurry is atomized at the top of a spray drying tower and forms porous granules with strong water absorption and fast dissolution. This product type is widely used for mainstream laundry powders and premium low bulk density powders.
At Meibao, we don't only supply detergent powder-we also provide the complete high tower detergent powder plant solution, so customers can start from product requirements and move directly into turnkey factory planning.

FAQs
Q1: What's the difference between high tower spray-dried powder and post-blended powder?
High tower spray-dried powder is formed inside the tower and has a porous structure (often lower bulk density). Post-blended powder is mainly mixed externally and usually has higher bulk density. The best choice depends on your product positioning, cost, and market habits.
Q2: Can you provide both detergent powder product and the production line?
Yes. We can start from product targets (density, appearance, performance) and develop the matching turnkey plant solution-including tower, slurry, dedusting, post-addition, packaging, and automation.
Q3: Can the plant be upgraded from an existing line?
Yes. We support renovation, capacity expansion, and section upgrades (e.g., tower revamp, dedusting improvement, post-addition system, packaging automation).
Q4: Can you match local fuels and utilities?
Yes. Hot air and energy systems can be designed based on available fuels/utilities and emission requirements.
