Abstract

The invention discloses a packaging bag evaporator for vacuum evaporation of compressed food. The evaporator comprises a heating medium outlet, a material outlet, a scraper, an evaporation cylinder, a heating medium inlet, a heating steam sleeve, a material inlet, a demister, a conduit, a condenser, a vacuum pump, an air outlet, a liquid storage tank and a liquid conveying pump. Structures of the evaporator are firmly connected, after a feed liquid is heated by steam and demisted by the demister, gas is converted into a liquid under cooling of the condenser, and the liquid is stored and can be recycled, so that a large amount of water is saved, and energy-saving and environment-friendly effects are realized; heating media enter the evaporator through the heating medium inlet, the heating speed is effectively increased, evaporation time is saved, and the production rate is increased; the vacuum pump pumps air in the evaporator out to create a vacuum environment, and the evaporator is applicable to non-direct contact evaporation; the scraper is arranged on the heating steam sleeve, the liquid is evaporated and concentrated quickly under the actions of gravity, centrifugal force and rotation of the scraper, and the practicality is guaranteed; the evaporator is high in evaporation speed, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to an evaporator, more precisely, a packaging bag evaporator for vacuum evaporating compressed food. Background technique [0002] The evaporator is a very important part of the four major components of refrigeration. The low-temperature condensed liquid passes through the evaporator, exchanges heat with the outside air, vaporizes and absorbs heat, and achieves the effect of refrigeration. It is mainly composed of two parts: heating chamber and evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid, which promotes the boiling and vaporization of the liquid; the evaporation chamber completely separates the gas-liquid two phases. The steam generated in the heating chamber contains a large amount of liquid foam, and after reaching the larger space of the evaporation chamber, these liquids can be separated from the vapor by self-condensation or the function of a demister. Usually the demist...
