Centrifugal film evaporator

Abstract

The invention belongs to the technical field of evaporation equipment, particularly relates to a centrifugal film evaporator, and provides the following scheme aiming at the problems that a centrifugal film evaporator in the prior art is low in working efficiency, the inner wall of a machine body is inconvenient to thoroughly clean, residual materials are easy to appear, the subsequent material quality is influenced, and the use effect is reduced: the centrifugal film evaporator comprises an evaporator shell and a rotary drum; a motor is fixedly installed on one side of the evaporator shell; a main shaft is fixedly connected to an output shaft of the motor; a spacer bush is fixedly connected to the outer side of the main shaft in a sleeving mode; and an evaporation body is fixedly connected to the outer side of the spacer bush in a sleeving mode. The spacer bush is connected with the main shaft, so that the spacer bush and the evaporation body rotate along with the main shaft, the evaporation time of materials on the evaporation body can be shortened, a liquid film is uniform, and the evaporation efficiency and effect can be improved; and the materials are uniformly distributed by driving the material spray pipe to rotate, and the scraper blade is driven to rotate and vibrate to efficiently clean residual materials.

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...
