Technical Parameters

The Thin Film Evaporator For Evaporation System is a highly efficient and reliable industrial equipment used in a wide array of applications. It is widely used for industrial and laboratory purposes in almost all industries, including the chemical, pharmaceutical, and food industries. It is specially designed for smooth and gentle evaporation of heat-sensitive products, and it provides an excellent solution for processing products that require a high level of purity, high viscosity, or high concentration.

The Thin Film Evaporator works by creating a thin, uniform film of the product on the heated wall of the evaporator. The heat applied to the wall vaporizes the product, which is then collected in a condenser. The evaporated product is almost completely free from contaminants and impurities, making it ideal for a wide range of applications. The Thin Film Evaporator boasts a very high evaporation rate, reducing the time required for processing, thus making it a cost-effective solution.

One of the most significant benefits of using the Thin Film Evaporator For Evaporation System is that it is energy-efficient since the high evaporative rate significantly reduces the energy required to evaporate a given volume of the product. This reduces the cost of operation and makes it a popular choice for most industries. The Thin Film Evaporator also requires minimal maintenance, which makes it easy to operate with little effort, thus increasing the overall efficiency of the machine.

Thermal sensitivity is a significant concern when it comes to the processing of temperature-sensitive products. Traditional evaporation techniques adversely affect the quality of the product. The Thin Film Evaporator For Evaporation System, on the other hand, is specially designed to handle low boiling point products by using a rotating wiper blade system that creates a thin film of the product. The heating medium is also distributed uniformly, ensuring that heat-sensitive products are processed without any loss of quality.

Another benefit of the Thin Film Evaporator For Evaporation System is the tight control it offers over the process parameters. The machine is equipped with sensors and controllers that monitor the temperature, pressure, flow rate, and other parameters, ensuring that the machine operates within the set limits. This results in consistent product quality, making it ideal for a range of applications.

Since the Thin Film Evaporator For Evaporation System is capable of processing a wide range of products, it is a versatile industrial equipment that offers numerous benefits. The machine can process products with high melting points, high viscosity, and high boiling points using a combination of high evaporation rates and low heat transfer rates.

In conclusion, the Thin Film Evaporator For Evaporation System is an excellent choice for any industry that requires the efficient and gentle processing of temperature-sensitive products. It is a versatile machine that offers numerous benefits, including energy efficiency, reduced maintenance, tight control over process parameters, and consistent product quality. Furthermore, the machine's ability to handle a wide range of products makes it an excellent investment for businesses looking for a reliable and versatile solution for their evaporation needs.

Introduction

The thin-film evaporator is a new type of high-efficiency evaporator that is forced to form a film by a rotating film wiper, flows at a high speed, has high heat transfer efficiency, and has a short residence time (about 10-50 seconds). It can perform falling film evaporation under vacuum conditions. It consists of one or more cylinders heated by a jacket and a film scraper rotating in the cylinder. The film wiper continuously scrapes the feed into a uniform thick liquid film on the heating surface and moves down; in this process, the low boiling point components are evaporated, and the residue is discharged from the bottom of the evaporator.

Performance characteristics

Small vacuum pressure drop: Material vaporized gas is sent from the heating surface to the external condenser, there is a certain pressure difference. In a general evaporator, this pressure drop (Δp) is usually relatively high, and sometimes even unacceptably high. The scraped film evaporator has a large space for gas to pass through, and the pressure in the evaporator can be regarded as almost equal to the pressure in the condenser. Therefore, the pressure drop is very small and the vacuum degree can reach 5mmHg. ·Low operating temperature: Due to the above characteristics, this allows the evaporation process to be maintained at a higher vacuum. Due to the increase in the degree of vacuum, the boiling point of the corresponding material drops rapidly. Therefore, the operation can be carried out at a lower temperature, which reduces the thermal decomposition of the product. Short heating time: Due to the unique structure of the wiper film evaporator, the film wiper has a pumping effect, which makes the residence time of the material in the evaporator very short; in addition, the high-speed turbulent flow of the film on the heated evaporator makes the product poor Will stay on the surface of the evaporator.

Application

The thin film evaporator is especially suitable for the evaporation of heat sensitive materials. High evaporation intensity: The lowering of the boiling point of the material increases the temperature difference with the heating medium; the function of the film wiper reduces the thickness of the liquid film in a turbulent state and reduces the thermal resistance. At the same time, in this process, the material is prevented from walling and scaling on the heating surface, and accompanied by good heat exchange, therefore, the overall heat transfer coefficient of the scraped film evaporator is improved. Large operating flexibility: It is precisely because of the unique performance of the scraped film evaporator that it is suitable for processing heat-sensitive and demanding smooth evaporation, high viscosity and sharply increased viscosity materials with increasing concentration. The evaporation process can also evaporate smoothly.

It can also be successfully applied to the evaporation and distillation of materials containing solid particles, crystallization, polymerization, and scaling.
