Scraped-Wall Mixing Tank

Heat transfer efficiency and anti-sticking walls

In processes that require rapid temperature rises or constant temperature reactions, if the materials adhere to the tank walls, an insulating layer will form, significantly reducing heat transfer efficiency and leading to increased energy consumption, uneven reactions, or localized overheating. The Kinding scraper-type stirred tank directly addresses this issue. Our spring or hydraulic scraper system maintains elastic contact with the inner wall of the tank throughout rotation, ensuring that 100% of the wall surface is immediately scraped clean. This enables the heat transfer medium in the jacket to be directly and efficiently transferred to all the materials, increasing the heat transfer coefficient by several times. When you evaluate the mixing equipment, this performance directly relates to your operating costs and product consistency.

Gentle Mixing and High Adaptability

Apart from efficient heat transfer, this equipment has unique advantages in the mixing method. It usually employs anchor-type, frame-type or helical-type main mixers, combined with a scraper, to generate a gentle but overall bulk movement, which is highly suitable for processing products that are sensitive to shear force, such as jams containing large fruit pulp and those that need to maintain their shape; chocolate slurries that require a slow induction in the crystallization process. In polymerization reactions, uniform heat dissipation and avoidance of excessive shearing are required for the resin prepolymer.

FAQ

Q: Can corrosive materials be processed?

A: Yes. The inner liner and the scraper can be custom-made using special materials such as Hastelloy alloy or titanium. Please provide detailed parameters regarding the corrosiveness of the materials.

Q: What is the maximum viscosity of materials that can be processed?

A: The standard model is suitable for materials with a viscosity of less than 500, 000 cP. For higher viscosities (such as over 1, 000, 000 cP), we can customize an enhanced drive system and a specially designed scraper-stirring paddle.

Q: Is there support for automated control?

A: Absolutely. It can integrate fully automatic temperature control, timing control, batch recording and report printing functions, and can be easily integrated into the intelligent factory system.
