Vertical Thin Film Dryer

The Vertical Thin Film Dryer is a state-of-the-art product that can effectively dry materials to their optimal condition quickly and efficiently. This high-tech machine is capable of achieving fast, homogeneous and gentle drying regardless of the materials’ characteristics or properties.

The Vertical Thin Film Dryer uses advanced drying technology that incorporates a special design of a vertical, conical-shaped dryer with a bottom driven agitator to promote continuous material flow, thus maximizing heat transfer and drying efficiency. This results in a reduced drying time, less energy consumption, and improved product quality, making it the perfect solution for any manufacturer looking to streamline their production.

The Vertical Thin Film Dryer is not limited to any specific materials. It can handle a wide range of products, including heat-sensitive materials and those that are prone to sticking or clumping during the drying process. This versatile machine can process everything from powders to solids, pastes, and suspensions, making it an ideal tool for the chemical, pharmaceutical, and food processing industries.

The Vertical Thin Film Dryer has several unique features that set it apart from conventional rim-type dryers. For instance, it has an all-welded construction with minimal contact points reducing the risk of contamination due to weld seams, and improving overall hygiene. This also makes it easy to clean, enhancing its use in applications requiring high levels of hygiene.

Furthermore, the machine’s agitator configuration and design prevent the accumulation of product on the drying surface, ensuring an even, consistent film of material on the walls of the dryer. This enables faster evaporation, maximizing the heat exchange efficiency. The dryer's compact design makes it easy to install and operate while requiring minimal floor space.

The Vertical Thin Film Dryer's operation is simple, yet impactful. The machine operates on the principle of evaporation, whereby the material to be dried is fed into the dryer by a feeding system or manually. The agitator, which is in direct contact with the material, rotates, creating a thin layer of material on the wall of the dryer.

The drying process begins with the application of heat to the dryer's shell. As the heat transfers through the thin film of material, moisture evaporates, turning into vapor that is then collected by the system's evaporator. The moisture-free material is then discharged from the dryer through a discharge system or valve.

The Vertical Thin Film Dryer comes in different sizes, ranging from laboratory-scale equipment to industrial-size machines that can handle large volumes of material while maintaining product quality. In addition, the equipment can be customized to meet specific manufacturer requirements, such as feed rates, effluent concentrations, drying times, and more.

Overall, the Vertical Thin Film Dryer is a game-changer for manufacturers looking to optimize their production process in terms of time and energy efficiency while still maintaining high standards of end-product quality. The equipment's state-of-the-art design, versatility, easy to clean, customisability, and high-quality manufacturing make it the perfect solution for any manufacturer looking to enhance their production capabilities.

Introduction

Vertical Thin Film Dryer consists of a cylindrically arranged body with a heating jacket and an internal rotor.The rotor is equipped with multiple rows of oscillating blades over the entire length of the dryer.The hinged blade spreads the wet feed product in a thin product layer on the heated wall and concentrates the product layer material in a concentrated manner.Thus,the volatile components are continuously evaporated from the product layer at a high evaporation rate.The hinged vane is designed with minimal clearance to prevent contamination of the heated surface by the product,but never in contact with the heated wall.

Working principle

The vertical film dryer consists of a cylindrical vertically arranged body with a heating jacket inside and a rotor.The rotor is equipped with rows of pendulum blades throughout the length of the dryer.The hinged blades spread the wet feed product on a heated wall as a thin layer of product and strongly mix the product layer material.Therefore,the volatile component is continuously evaporated from the material layer having a high evaporation rate.The hinge vanes are designed with minimal clearance to prevent the heated surface from being soiled by the product,but at the same time not in contact with the heated wall.The product enters the top of the dryer.Evaporation begins after heating to the boiling point.The initial solids form in the slurry zone,and as the volatiles evaporate and the hinged blades continue to shear,the paste material continues to decompose into powder.The final solid product is discharged by gravity at the bottom of the dryer by a suitable airlock
