1. Overview and Application Scope
The scraper thickener—also known as the scraper thickening tank, scraper evaporator, or vacuum scraper thickener—is suitable for the evaporation and concentration of liquid materials in pharmaceutical, chemical, food, and other industries. Specifically, it is particularly applicable to heat-sensitive materials and high-viscosity materials, as well as foaming and scaling-prone materials. Moreover, it features high evaporation and concentration efficiency. During operation, the scraper scrapes the material into an extremely thin and uniform film on the heating surface and pushes it downward for rapid evaporation, which in turn ensures a fast evaporation rate.
2. Equipment Material and Overall Configuration
2.1 Material Selection and Corrosion Resistance
We manufacture the entire equipment from stainless steel 304/316L, which provides excellent corrosion resistance and meets the hygiene and durability requirements of various industries.
2.2 Complete Set Configuration and Structure
The complete set of equipment includes an evaporator, condenser, cooler, liquid receiver, internal connecting pipes, valves, supporting instruments, and more. Additionally, it has an aesthetically pleasing and unique structure. We apply a matte finish to the equipment shell, and the production process strictly complies with the GMP quality standards for pharmaceutical production.
3. Core Functions and Applicability
The scraper thickener integrates stirring and evaporation functions, which together achieve good concentration results. Furthermore, it is especially suitable for the heat transfer, evaporation, and concentration of high-viscosity materials, addressing the challenges of processing such materials efficiently.
4. Key Components and Advantages
4.1 Defoaming Device
We equip the upper part of the equipment with a defoaming device, which effectively prevents foam entrainment and flooding phenomena. Moreover, the filter area of the defoamer is compression-molded, with smooth transitions and no dead corners, ensuring thorough defoaming and easy cleaning.
4.2 Structural and Hygiene Advantages
The equipment has a compact structure with a small footprint, making it suitable for factories with limited space. Additionally, we make all materials of stainless steel, and we polish both internal and external surfaces to comply with GMP requirements, ensuring hygiene and safety for material processing.
4.3 Motor Configuration
We adopt advanced domestic reduction motors for the equipment. These motors have the advantages of low energy consumption, excellent performance, and high efficiency. They also feature small vibration, low noise, and a compact and delicate design, which enhances the overall stability and service life of the equipment.
