An Discussion of Vegetables Freezing Rates of Vacuum Cooling and Refrigerator Cooling

Advanced Materials Research, 2013
Vegetables are perishable agricultural products. In order to prolong the fresh-keeping period of agricultural products, vegetables should be cooled rapidly soon after harvest. The pre-cooling of vegetables after harvest is the first link of cold chain; therefore, its especially important.

Factor affecting the cooling rate of lettuce in vacuum cooling installations

International Journal of Refrigeration, 1987
Abstract Commercial-scale experiments carried out during the last five years have shown that the cooling time of a head of lettuce, wrapped in PVC film and packed in a carton, can vary from 25 to 65 min, depending on the design of the vacuum installation.

Vacuum Cooling Technology for Pre-cooling of Cherry Fruits

2019
The scientific and experimental analysis of vacuum cooling of fruit cherries is shown in this article. Fruit and vegetable products that contain enough of water can be cooled by the vacuum cooling process, which increases the efficiency of evaporation by reducing the pressure and boiling water temperature.

Vacuum cooling of liquids: mathematical model

Journal of Food Engineering, 2004
Abstract Vacuum cooling is very often used when a fast temperature decrease of products is required. Particularly food, pharmaceutical and other industrial areas take advantage of a fast cooling process which reduces high temperature effects and minimizes the time during which, for example, an increased growth of microorganisms can occur.

Vacuum cooling combined with hydrocooling and vacuum drying on bamboo shoots

Applied Thermal Engineering, 2006
Vacuum cooling technology is a proven technology widely applied on post-processing of harvested agricultural products. However, there are few researches on its application on root/stem vegetables. Bamboo shoot is a type of root/stem vegetables with high economic value in Taiwan. It is also enjoyed by Taiwanese and Asian people.

Effect of vacuum cooling on mushroom browning

International Journal of Food Science & Technology, 1987
SummaryThe effects of two cooling methods and two storage temperatures on mushroom quality, anatomy and weight loss were compared. Mushroom quality was assessed as a function of cap browning and hyphal structure. Storage of mushrooms at 5°C conserved quality and reduced weight loss as compared with those stored at 18°C.
