Deep corn processing machinery are crucial to produce newtol. It plays an important role in grinding and evaporation processes.

Hydrolysate goes to IX process after neutralization, decoloration, evaporation and concentration. Outwardly, evaporation only removes moisture to increase concentration of hydrolysate. In fact, it also purifies half finished products. 

Evaporators of deep corn processing machinery are central circulation tube evaporator, rising or falling film evaporator, scraper film evaporator. Rising or falling evaporation is more suitable for neutralization of decoloration solution. The film uses longer tubulation to get thinner liquid film, faster line speed and better heat transmission effect.
