Problems solved by technology

[0003] During the concentration process of this standard external circulation evaporator, after the material liquid enters the evaporation tank from the heating tank, the gas-liquid separation is not complete, and part of the secondary steam is wrapped in the material and enters the bottom of the heating tank, especially when the material concentration reaches more than 20%. Especially in the end, the evaporation efficiency is obviously reduced, and the equipment efficiency is very low; at the same time, the standard evaporator liquid collector generally adopts double-pass or two parallel connections.
The operating procedures are cumbersome, and operators are prone to misoperations that cause materials to run out and equipment to run abnormally

Abstract

The invention discloses an outer circulating evaporator. The outer circulating evaporator comprises a heating tank and an evaporating tank, wherein the upper part of the heating tank is connected to the middle part of the evaporating tank through an upper circulating pipe; the lower part of the heating tank is connected to the lower part of the evaporating tank through a lower circulating pipe; areinforced evaporating device is arranged in the evaporating tank. The outer circulating evaporator solves the problem that the evaporating efficiency gradually decreases based on the concentration; in addition, the discharging operation is convenient, quick and safe.

Description

technical field [0001] The invention relates to the field of food processing machinery, in particular to an external circulation evaporator. Background technique [0002] The basic working principle of the external circulation evaporator: After the material liquid is heated to boiling in the tube of the heater, the solution is vaporized, and the heat energy is converted into kinetic energy of upward movement, rising from the lower part of the heater to the upper part and entering the evaporator; due to the heating tank There is a large gravity difference between the internal vapor-liquid mixture and the unheated feed liquid in the circulation pipe, and the natural circulation of the feed liquid is produced under the action of the expansion kinetic energy and the gravity difference. Due to the evaporation under the action of vacuum, the boiling point of the feed liquid decreases, and the vapor-liquid mixture from the heating tank enters the evaporation tank for vapor-liquid s...
