Abstract
PURPOSE: To precool vegetables and fruits before refrigeration, uniformly, rapidly, without evaporation of water, and to prevent the loss of freshness, by changing the pressure of chilled air to refrigerate the green vegetables and fruits periodically within a range 200 mmHg above and below the atmospheric pressure.
CONSTITUTION: Harvested vegatables or fruits are packed in packing cases 11, and stacked in a refrigerating chamber 1. The chamber 1 and the pre-chamber 2 are cooled by putting the refrigerators 6 and 7 in motion. The blower 8 is rotated to the normal direction, and the blower 8' to the reverse direction, thereby increasing the pressure in the refrigerating chamber 1. After a temporary pause, the directions of the blowers 8 and 8' are reversed to decrease the pressure in the chamber 1. The refrigeration of vegetables is carried out by repeating the application and the reduction of pressure, thereby changing the pressure periodically and intermittently, within the range 200 mmHg (about 1/50 atm.) above and below the atmospheric pressure. The pressure fluctuation is effective to enhance the convection of chilled air in the chamber, and to maintain the freshness of the wegetables, etc.
