Design and test of steam-injected continuous scrambled egg device.

To solve the existing problems of low yield, uneven quality, and single form of industrially scrambled eggs, we have developed a continuous high-output steam scrambled egg device based on the principle of steam injected. By establishing calibration curves for egg, oil, and steam flow rates, determining the key parameters of the equipment, and simulating the heat transfer process between steam and egg by Computational Fluid Dynamics (CFD), we created the device and verified its production performance. The results show that the capacity of this device can reach 104.4 kg/h, which greatly improves production efficiency. By precisely adjusting the steam flow, this device can produce scrambled eggs in the form of blocks, thick slices, thin slices, and broken. Moreover, the differences between the scrambled eggs produced by this device and the traditional frying pan were not significant in terms of color, taste and sensory evaluation (p > 0.05). Most importantly, this device produces scrambled eggs with better elasticity, softer texture, and better overall uniformity of maturity to achieve consumer satisfaction. This study provides technical support for the industrialized continuous production of Chinese egg dishes.
