  • The evaporator has been widely used in the amino acid industry, including the evaporation and concentration of lysine, threonine and monosodium glutamate. Evaporative concentration is the key production process in many industries. However, the evaporator is not a universal evaporation concentration system. Design, material selection, manufacture and use of high efficient evaporator should be compatible with the properties and technological requirements of the concentrated materials. Only in this way, the evaporator can give full performance and play an increasingly important role in the production of the amino acid industry.

    Multi effect evaporator main features:

    • The heat pump can be used reasonably, to reduce the steam consumption and cooling water consumption;
    • The production capacity is developed to large, continuous and automatic. Simple structure, convenient cleaning, operation and maintenance;
    • multi effect evaporation is carried out under the vacuum condition with lower evaporation temperature, which can retain the original color, smell, etc. of the processed material to the maximum.

    Lysine dehydration multi effect evaporator

    Take three effect evaporator working process as an example:

    1. The material preheating by condensate water in first plate heat exchanger, then preheating by steam in second plate heat exchanger to more than 50 DEG c;
    2. The material enters the Striped distillation and deamination tower, which is placed above the three effect separator, and takes off the ammonia in the production process and reclaims it;
    3. The material enter third effect evaporation, then enter to first effect evaporation; finally enter to second effect evaporation and discharged out of evaporator;

    20-50 lysine concentration multi effect evaporator

    The type 20-50 lysine is about 20% of the feed concentration before evaporation, and the concentration of the discharge is about 50%. The concentration of feeding and discharging is higher.

    Take four effect evaporator working process as an example: The first and second effects were evaporated by central forced circulation, and the third and fourth effect was evaporated by falling film evaporation.

    The evaporation sequence of the material is: The material enters the fourth evaporator evaporation, then enter into the third evaporator evaporation, then enter into the first effect of central forced circulation evaporation; finally enter into the second evaporator central forced circulation evaporation.

    Threonine multi effect evaporator

    Threonine is accompanied by crystallization in the concentrated production, so its multi - effect evaporator is also more complex.

    Threonine has an extremely important physiological function in animals. The addition of threonine to the feed has the following characteristics:

    • The amino acid balance of the feed is adjusted to promote the growth of livestock, and the meat quality can be improved.
    • To improve the nutritive value of the feed with low amino acid digestibility;
    • Reduce the cost of feed raw materials.
