Handling and transportation of high‐fat cream needs to be done gently; otherwise, undesirable destabilisation of the fat emulsion is likely to occur. This study delves into the processing factors that cause the disruption of fat emulsion in high‐fat cream. The cream viscosity was 48.6 mPa.s at 7.2°C. Results revealed that pump screw pitches of 32 and 43 mm and rotational speeds of 264 and 464 LPM were the significant factors that caused the butter formation in the cream. There was significant emulsion breakdown, regardless of the degree of fat crystallisation at 6.5 ± 0.5°C for a minimum of 12 h.

“…The results indicate that when the number of grids ranges from 700,000 to 1,400,000, the change of the equivalent stress values of four points is small. Therefore, it can be proven that the number of grids has little effect on the results, and 782,792 grids can be selected as the calculation grid in this study [24].…”

To accommodate special applications where installation space is limited and noise and vibration requirements are high, a new triple screw pump structure was proposed, which was integrated into a servo motor. The design optimizes the profile of the master and slave screws of the embedded triple screw pump. The temperature and pressure fields of the embedded triple screw pump, as well as the heat transfer and pressure distribution between the fluid in the pump and the screw, were investigated through a thermal-fluid-structure approach. The deformation and stresses of the screw were compared for three operating conditions: temperature loading, pressure loading, and thermal-fluid-structure coupling. The results show that the deformation and stresses in the screw tended to increase with increasing pressure and temperature and the pressure load caused more significant deformation and stresses in the screw than the temperature load. The screw deformation caused by pressure loading was found to be the main factor affecting the thermal-fluid-structure coupling. The screw deformation after coupling was smaller than the sum of the screw deformation caused by individual temperature and pressure loads, and the stress values were the same. The results indicate that the coupling action weakens the deformation and stresses in the master and slave screws.
