Problems solved by technology

In addition, for different materials, sometimes some too simple single-effect evaporation can not complete the work task in one step, and the multi-effect evaporation with high cost is a waste of resources, which requires preheating of materials to improve work efficiency

Abstract

The invention relates to the technical field of chemical evaporation heating equipment, and provides a falling-film evaporator for preparing spices. The falling-film evaporator comprises an evaporation chamber, wherein a heat exchange tube bundle is arranged in the evaporation chamber; a gas-liquid separator is arranged at the lower part of the evaporation chamber. The falling-film evaporator is characterized in that a steam inlet, a condensate water and a condenser are arranged on the evaporation chamber; a material inlet is formed in the top part of the evaporation chamber; a material distributor is arranged at the lower part of the material inlet; the gas-liquid separator is connected with a separation chamber through two pipes which are parallel from top to bottom; a secondary steam outlet is formed in the top part of the separation chamber and is connected with a compressor; the compressor is connected with the two pipes; one pipe is connected with the steam inlet; and the other pipe is connected with a material inlet pipe. To-be-heated materials are preheated by the compressor and a secondary steam recovery needle; the compressed steam is fed into the evaporation chamber aiming at the materials which do not need to be preheated; available resources are effectively utilized; the energy consumption is reduced; and meanwhile, the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of chemical evaporation and heating equipment, in particular to a falling film evaporator for spice making. Background technique [0002] Falling film evaporation is to add the feed liquid from the upper tube box of the heating chamber of the falling film evaporator, and through the liquid distribution and film forming device, it is evenly distributed into each heat exchange tube, and flows down in a uniform film along the inner wall of the heat exchange tube. In the process of flowing down, it is heated and vaporized by the shell-side heating medium, and the generated steam and liquid phase enter the separation chamber of the evaporator together. After the vapor and liquid are fully separated, the steam enters the condenser for condensation (single-effect operation) or enters the next-effect evaporator As a heating medium to achieve multi-effect operation, the liquid phase is discharged from the separation ...
