Product introduction

Rising film evaporator is a natural cycle, it is mainly the evaporation chamber (or separator), a heater and a circulating pipeline, a non-return valve, hydraulic ejector, water tank, centrifugal pump, water pump and discharge operation table etc.
The feed liquid is heated by the bottom of the heating tube, and the steam is transferred to the liquid in the pipe outside the tube. Tube material heating and evaporation of liquid is divided into three parts:
The bottom is completely filled with liquid and the heat is mainly transmitted by convection.
Intermediate part begins to produce steam bubble, make material fluid produce rising force.
The highest of two due to the expansion of the evaporation to produce a strong upward force, material liquid is thin in the tube in tube upward, the top is a spray, into a vapor liquid separator with high speed, under the action of centrifugal force and two steam separation, two steam discharged from the top of the separator. A portion of the concentrate is heated by evaporation from the lower end of the pipe to a concentration of concentrated liquid from the bottom of the separator. Rising film evaporator is generally a single flow pattern, that is, the feed can be discharged at a concentration to achieve the concentration of finished products.
Basically the same as the structure of falling film evaporator, the main difference is that the material liquid is entered from the bottom of the heating chamber, the liquid enters the heating pipe, heating rapidly boiling vaporization; steam rises quickly in the tube, the liquid is to speed up the steam driven along the tube wall to form a film and continues to rise, evaporation. The separation chamber of steam and liquid phase generated into the evaporator, vapor liquid after full separation, a low temperature steam compressed by the compressor, the temperature, the pressure increases, the enthalpy increase, and then enter the heat exchanger condensation, in order to make full use of the latent heat of steam and liquid by the separation chamber.

Product features

1, Small area, low space height, compact structure, low cost, less investment;
2, Often for continuous operation, or intermittent operation;
3, Convenient cleaning, low labor intensity, and can be used cleaning liquid circulation cleaning;
4, Material circulation is good, normal operation is not easy coking.

Product use

The rising film evaporator is suitable for vacuum concentrating of liquid foods such as milk, juice, syrup, honey, whey and vegetable protein liquid. It is also used for vacuum concentration of biological, pharmaceutical and herbal extracts.
