A centrifugal thin film evaporator

Abstract

The invention belongs to the technical field of evaporation equipment, especially a centrifugal thin-film evaporator, aiming at the low working efficiency of the centrifugal thin-film evaporator in the prior art, and it is inconvenient to clean the inner wall of the body thoroughly, and residual materials are easy to appear, which affects the follow-up The quality of materials reduces the problem of its use effect. The following scheme is proposed, which includes an evaporator casing and a rotating drum. A motor is fixedly installed on one side of the evaporator casing, and a main shaft is fixedly connected to the output shaft of the motor. The outer fixed sleeve of the main shaft is connected with a spacer, and the outer fixed sleeve of the spacer is connected with an evaporation body. In the present invention, by connecting the spacer with the main shaft, the evaporator is carried by the spacer to rotate with the main shaft, so that the evaporation time of the material on the evaporator can be shortened and the liquid film is uniform, thereby helping to improve the evaporation efficiency and effect. It drives the material nozzle to rotate to achieve uniform material distribution, and drives the scraper to rotate and vibrate to efficiently clean the residual material.

Description

technical field [0001] The invention relates to the technical field of evaporation equipment, in particular to a centrifugal thin film evaporator. Background technique [0002] Centrifugal thin-film evaporator has the advantage of short evaporation time, and the evaporation process can be completed in only 1 second or even less than 1 second, so as to ensure that the extract remains unchanged in its original state. Due to the large amount of materials, some natural pigments such as wolfberry pigment, lycopene, carotene and other natural pigments are very heat-sensitive, and their properties will change when the temperature is high and the time is long, which will affect the quality if it is light, and cause the material to be scrapped if it is serious. Therefore, vacuuming is used to reduce the boiling point temperature of the solvent during extraction. Secondly, due to the fast flow rate of thin film evaporation and high heat transfer efficiency, it can reach about 5000 kca...
