Abstract

The invention discloses a vacuum concentrator. The vacuum concentrator comprises a heater and an evaporator, wherein a gas outlet of the heater is communicated with a steam inlet of the evaporator; a condensing passage is arranged inside a condenser; a steam outlet of the evaporator is communicated with an inlet of the condensing passage; a liquid collector is arranged below the condenser; the condensing passage stretches into the liquid collector from the top of the liquid collector; a vacuum tube is arranged on the liquid collector; the distance between the vacuum tube and an outlet of the condensing passage is proper when condensate flows out of the outlet of the condensing passage and is not brought out of the liquid collector by a vacuum system; a liquid draining port is connected with a water draining pump; and the outlet of the condensing passage is positioned above the liquid surface of the condensate inside the liquid collector. The vacuum concentrator can be used for concentrating liquid materials in chemical, pharmaceutical and food industries and the like.

Description

technical field [0001] The invention relates to a vacuum concentrator, which belongs to the technical field of evaporation equipment. Background technique [0002] In the chemical, pharmaceutical and food technical fields, it is often necessary to concentrate the feed liquid. The concentrator is just the equipment used to evaporate the solvent in the feed liquid and extract high-purity feed liquid. Concentrators are divided into atmospheric concentrators and high-pressure concentrators according to their pressures. For atmospheric concentrators, in order to improve their concentration efficiency, a higher concentration temperature is required, which also increases energy consumption accordingly; When the material contains heat-sensitive substances, the heat-sensitive substances are easily denatured at high temperature, which affects the stability of the concentrated product quality. [0003] In order to overcome the above shortcomings of atmospheric concentrators, the resea...
