Study on heat and mass transfer of sugarcane stem during vacuum pre-cooling
Journal of Food Engineering, 2021Abstract Heat and mass transfer of fruit and vegetables is significantly affected by vacuum pre-cooling end temperature (VPET). The simulations and experiments on the heat and mass transfer of sugarcane stem were performed to investigate the trends of total system pressure, temperature distribution, the water evaporation rate, weight loss, and ...

Effect of Vacuum Pre-Cooling on Quality Changes of Spinach during Cold Storage
Advanced Materials Research, 2013Vacuum pre-cooling technique was used as a rapid cooling method for leafy vegetables such as lettuce, spinach and so on. Experiments were carried out to investigate the effect of vacuum pre-cooling on physiological activities during cold storage. The results revealed that the increase in weight loss and membrane permeability was inhibited, and the ...

Response of Spinach in Controlled Pressure Conditions during Vacuum Pre-Cooling
IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2001Abstract The decrease in pressure inside the enclosed chamber was controlled between 2.4 kPa and pre-set minimum pressure of 0.61 kPa to follow a linear and exponential decay functions during vacuum pre-cooling. The change in the pressure profiles, which reduces cooling rates, increased moisture loss and decreased temperature reduction per percent ...

Discussion on the Vacuum Pre-Cooling Rate of Vegetables
Applied Mechanics and Materials, 2010The cold chain in low temperature logistics is closely related to modern life. Temperature control is required when vegetables and fruits are collected, and pre-cooling is the first step of the cold chain, so it is very important. Vacuum pre-cooling decreases the temperature of vegetables and fruits rapidly and uniformly as the water on the vegetable ...
