Study on the Effect of Salt Modulation upon the Maize Drying Process
A maize drying method of salt modulation is presented in this paper.Based on the thin-layer drying experiment1,the effects of drying air temperature and salt amount on moisture removal rate is analyzed2,and mathematical model equation is established on relationship between maize moisture ratio and drying time3.The experiment result shows that:a reasonable choice of the amount of salt,air temperature and other process parameters is useful to improve drying rate of maize.Salt modulated drying curve is exponentially.The more salt is added in,the faster the moisture removal rate.However,in the case of excessive salt,there may be a critical point of moisture change in the amount of salt until this point the faster the higher the salt amount,whereas the slower; if the critical changing point is higher than the safety moisture point,generally it will conductive to the maize moisture removal process.
