GB series scraper film evaporatorScope and working principle

The GB type rotating scraper thin film evaporator is a new type of high-efficiency evaporator that uses a rotating scraper to force film formation and can perform falling film evaporation under vacuum conditions It has a high heat transfer coefficient, high evaporation intensity, and short overcurrent time Great operational flexibility Especially suitable for evaporation concentration, degassing and desolvation, and distillation purification of heat sensitive materials, high viscosity materials, and easily crystallized granular materials. Therefore, in the chemical and pharmaceutical industries The food and fine chemical industries have been widely used.

GB series scraper film evaporatorPerformance and Features
This evaporator adopts a centrifugal sliding groove rotor, which is currently a foreign structural evaporator that can form a thin film even at low flow rates. The sediment in the treatment liquid attached to the inner wall surface of the evaporation section of the cylinder can be quickly removed by a movable scraper Compared to fixed gap scraper evaporators The evaporation rate can be increased by 40-69.

Has the following performance and characteristics:

1. High heat transfer coefficient and high evaporation capacity The evaporation intensity can reach 200kg/m2.hr, and the thermal sensitivity efficiency is high,

2. The shaking heating time is short Between about 5 seconds and 10 seconds, working under vacuum conditions is more advantageous for thermosensitive materials, ensuring product quality.

3. It can adapt to a wide range of viscosity changes and handle both high and low viscosity substances The viscosity of the material can reach up to 100000 centipoise (cp).

4. Change the rotation direction of the scraper groove The maintenance time of materials in the evaporator can be adjusted.

The inner wall of the simplified evaporation section has been precision filed and polished, making the surface less prone to coking Scaling up.

6. Easy to operate Product indicators are easy to adjust Under closed conditions, continuous production can be achieved through self-control.

The evaporator has a small footprint The structure is simple Easy to maintain Easy to clean.
