Abstract

Ultrasound has previously been proven to improve the efficiency of apricot kernels debitterizing process at the laboratory level, while the information on the industrial equipment is not available. In order to investigate the feasibility in industrial application, a continuous countercurrent pilot ultrasound equipment was developed. The mechanical structure and parameters of the prototype were designed by AutoCAD software, and the acoustic pressure distribution with different transducer arrangements and frequencies was simulated by COMSOL Multiphysics software. The pilot test was conducted on the prototype to optimize the conditions and verify the debitterizing effect. Overall, the equipment was consisted of five sections including crushing, conveying, ultrasonic, water circulation and control systems with the dimension of 6670 × 980 × 2850 mm. The optimal installation parameters for the transducers were frequency of 28 kHz, spacing 225 mm and angle 100°. Compared to the industrial debitterizing time for 48 h, it could be shortened to 2.5 h using the developed prototype and the loss of apricot kernel components could be effectively reduced. The eco-efficiency comparison indicated that the equipment is energy-saving and environmentally friendly for industrialized production. In conclusion, the equipment prototype might be used for the industrial debitterizing of apricot kernels so as to greatly reduce the time and the resource waste.

杏核快速脱臭中试超声设备的研制及其优化参数

在实验室水平上，超声波已被证明可以提高杏核脱臭过程的效率，而工业设备的信息则不可用。为了探讨工业应用的可行性，研制了一种连续逆流式中导超声设备。利用AutoCAD软件对样机的机械结构和参数进行了设计，并利用COMSOL Multiphysics软件对不同换能器布置和频率下的声压分布进行了仿真。在样机上进行了中试，优化了工艺条件，验证了脱臭效果。总体上，设备由破碎、输送、超声波、水循环和控制系统五部分组成，尺寸为6670 × 980 × 2850 mm。换能器的最佳安装参数为频率为28 kHz，间距为225 mm，角度为100°。与工业脱酸时间48h相比，该工艺可将脱酸时间缩短至2.5 h，有效降低了杏核成分的损失。生态效率对比表明，该装置节能环保，适合工业化生产。综上所述，该设备样机可用于杏核的工业脱臭，从而大大减少时间和资源浪费。
