Fully Enclosed Drum Flakers and Steel-Belt Cooling Flakers
Tianjin Huabang provides engineered flaking and cooling systems to continuously solidify molten products into stable, free-flowing solids for conveying, screening, storage, and packaging. This equipment family is developed for demanding chemical service, especially where the product is high-melting, sublimating, oxidation-sensitive, moisture-sensitive, or requires enclosed downstream handling.
Fully Enclosed Heavy-Duty Water-Channel Drum Flaker
Product Description
A continuous drum-based flaking system designed for high heat flux removal, stable flake thickness, and enclosed operation. The core feature is Huabang’s heavy-duty internal water-channel cooling structure, developed to maximize turbulent coolant flow and heat-transfer performance. The fully enclosed, heavy-duty drum flaker is a continuous solidification system that converts molten feed into thin, uniform flakes through controlled deposition on a cooled, rotating drum, followed by precision scraping and discharge. It is specifically engineered for products that require rapid and stable heat removal, strict enclosure, and repeatable flake geometry.
Huabang’s heavy-duty design adopts a patented internal water-channel structure inside the drum. The coolant flow path is engineered to maintain high turbulence within the cooling channels, thereby increasing Reynolds number, reducing the thermal boundary layer, and significantly improving convective heat transfer. The result is faster heat removal, more uniform drum surface temperature, and more stable production under industrial operating conditions. This design approach has been developed through long-term simulation work, thermal optimization, and field operating experience.
Standard Flaker Package
A conventional equipment supply including the flaker body, cooling drum, scraper system, drive assembly, enclosure, local instruments, and utility/process interfaces. This arrangement is suitable where field piping and hook-up are completed within the broader plant installation scope.
Skid-Mounted Integrated Flaker System
A higher-integration package in which the flaker is mounted on a unified skid together with process piping, valves, instruments, utility manifolds, a local control cabinet, and a structural base. This arrangement improves installation quality, reduces field work, shortens commissioning time, and provides clearer battery limits for export and EPC projects. The skid-mounted concept is illustrated in the attached flaker comparison sheet.
Typical skid-mounted scopes include:
· Flaker main machine
· Cooling-water inlet and outlet manifold
· Feed inlet and overflow/return piping
· Drain and vent piping
· Temperature, pressure, flow, and level instruments
· Pneumatic and manual valves
· Local control panel or junction box
· Integrated base frame and maintenance access provisions
Drum Flaker Model Selection
Common design basis for the series
Flake thickness: 0.05-3.00 mm, adjustable according to process requirement
Cooling medium: cooling water, chilled water, or glycol solution, depending on thermal duty
Heat-preserving medium: steam, hot water, or thermal oil, depending on product characteristics
Construction: heavy-duty enclosed water-channel drum design
Supply format: standard package or skid-mounted integrated package
Flange standard: available to ASME, ISO, or project-specific requirements.
Actual capacity depends on melt viscosity, feed temperature, latent heat load, required flake thickness, coolant conditions, and final discharge temperature. Final equipment sizing is confirmed by process calculation.
Steel-Belt Cooling Flaker
A continuous belt-based flaking system in which molten product is distributed as a controlled layer onto a moving stainless-steel belt, rapidly cooled, solidified, and discharged as flakes or broken sheet product. This configuration is well-suited to wider product beds, longer cooling paths, and large-capacity continuous production.
Together, these systems provide a coherent downstream solution for molten-product finishing in anhydride, sulfur, wax, resin, and specialty chemical applications.
Product Description
The steel-belt cooling flaker is a continuous cooling and solidification system for molten products that benefit from sheet-form deposition and controlled residence time on a moving belt. In this system, molten material is delivered through a heated feed system and evenly distributed as a thin layer across a stainless-steel cooling belt. The layer is cooled from below by recirculating cooling water and, where required, from above by controlled air cooling. After solidification, the product is discharged as flakes, broken sheets, or cut solids suitable for downstream transfer and packaging.
Compared with drum-based systems, the steel-belt cooling flaker offers a longer, more visible cooling path, a wider effective product bed, and is particularly well-suited to products that require gentle solidification, a wide distribution width, or larger production capacities. It is well-suited to the continuous finishing of sulfur, waxes, resins, hot-melt products, and selected anhydride services.
Steel-Belt Cooling Flaker Model Selection
Common design basis for the series
Belt speed: adjustable according to thermal load and capacity
Cooling medium: recirculating cooling water, with optional chilled water section
Product form: flakes, broken sheet, or strip-like solids, depending on distributor and discharge design
Supply format: open or enclosed frame, with optional integrated cutting/breaking device
Construction: stainless-steel belt with engineered support, tracking, and cooling system
Actual capacity depends on product melting point, viscosity, layer thickness, belt speed, feed-temperature stability, cooling-water temperature, and discharge specification.
Engineering Considerations for Model Selection
Selection of a steel-belt cooling flaker is typically based on:
- Required throughput
- Product melting point and viscosity
- Allowable product residence time
- Target product thickness and discharge form
- Belt width utilization
- Cooling-water availability
- Enclosure and vapor-control requirement
- Downstream breaker, screener, and packaging interface
For products with higher viscosity or narrow processing windows, attention is paid to distributor design, heated-feed stability, and cooling-zone balance. For larger-capacity duty, wider belts and longer effective cooling areas are generally favored to maintain a manageable layer thickness and reliable release.
