Scraper Evaporator

Among the specific types of evaporators, one that needs to be contacted is the scraper evaporator, which is also a commonly used type. Therefore, from a professional perspective, scraper evaporator is a new type of evaporator with strong adaptability, suitable for materials with high viscosity, heat sensitivity, easy crystallization and scaling, and has high usage effects.

Introduction

1. The basic structure and operation of a scraper evaporator
The scraper evaporator is made up of two major parts: a heating clamp and a scraper. The jacket is also heated with steam, and the scraper is mounted on a rotational shaft. Furthermore, there is a gap between the scraper and the inner wall of the heating tube clamp, which is normally between 0.5mm and 1.5mm.
The evaporator works by preheating the source material liquid and adding it along the tangent direction. It is evenly spread on the inner wall by gravity and a spinning scraper to make a thin layer. During the descent, it continues to evaporate and concentrate until being ejected from the evaporator's bottom. The secondary steam produced is vented from the top.
2. Scraper evaporator performance and features
1) The scraper evaporator has a high heat transfer coefficient, a big evaporation capacity, and an evaporation intensity of 200kg/m2, resulting in a high heat efficiency.

2) The material's heating time is short, about 5 to 10 seconds. Furthermore, it is ideal for thermosensitive materials under vacuum circumstances. Furthermore, numerous components can be retained intact during the evaporation process, ensuring product quality.
3) The adaptation range of material viscosity is very broad. Furthermore, diverse usage requirements can be addressed by altering the rotation direction of the scraper groove.
4) The evaporator's general functioning is simple, it takes up little space, and it is simple to clean and maintain. Automatic and continuous production can be done in a locked condition.

5) The appropriate materials can be thermosensitive materials, materials with consistent evaporation needs, high viscosity materials, materials with increased viscosity as concentration increases, and materials with a very smooth evaporation process. As a result, it has a very broad range of applications.
3. Scraper evaporator operation principle
When the scraper evaporator material reaches the evaporator, it is accelerated and spread, generating a thin flowing film on the heating surface. The light components then travel downstream into the separator, where they are treated before entering the external condenser or the following operation. The recombination component creeps along the heating wall and exits through the tiny port.
