Embodiment 1

[0037] Set a ventilation window on the cover of a fresh-keeping box with a volume of 25 liters, and its area is 0.04m 2 . Put 6kg of cherries into the fresh-keeping box and store and transport them at -1°C to 1°C. The cherries are picked before 11:00 a.m. and ripen at 8:00 a.m., soaked in cold water at 2°C for 10 minutes within 4 hours, and then drained for 1 hour at 1°C to 4°C. According to the calculation formula, it can be known that the air permeability of the required breathable membrane is 10000mL / 24h m 2 101kPa. Choose this type of breathable membrane to be placed on the vent window. Under these conditions, the cherries are stored for about 50 days, and the intact rate is over 98%.

Embodiment 2

[0039] Set 2 ventilation windows on the cover of the fresh-keeping box with a volume of 200 liters, the area of ​​which is 0.09m2 2 . Put 80kg of cherries into the fresh-keeping box and store and transport them at 4°C to 6°C. The cherries are picked before 10:00 a.m. and ripen by 9:00 a.m., soaked in cold water at 2°C for 10 minutes within 4 hours, and then drained for 1 hour at 1°C to 4°C. According to the calculation formula, it can be known that the air permeability of the required breathable membrane is 35000mL / 24h m 2 ·101kPa or so. Choose this type of breathable membrane to be placed on the vent window. Under these conditions, the cherries are stored for about 30 days, and the intact rate is over 98%.

Embodiment 3

[0041] Set 4 ventilation windows on the cover of the fresh-keeping box with a volume of 1000L, and the area is 0.36m 2 . Put 500kg of cherries into the fresh-keeping box and store and transport them at -1°C to 1°C. The cherries are picked before 8:00 a.m. and ripen by 8:00 a.m., soaked in cold water at a temperature of 2°C for 10 minutes within 3 hours, and then drained for 1 hour at 1°C to 4°C. According to the calculation formula, it can be known that the oxygen permeability of the breathable membrane is 12000mL / 24h m 2 ·101kPa or so. Choose this type of breathable membrane to be placed on the vent window. Under these conditions, the cherries are stored for about 40 days, and the intact rate is over 98%.

[0042]The invention provides a fresh-keeping box for transportation and storage. The box body and the box cover are sealed to prevent gas from exchanging with the outside world through the gap between the two. A ventilation window is arranged on the box cover, and a br...

Abstract

The invention relates to the technical field of fruits and vegetables preservation and discloses a storage preservation box. The storage preservation box includes a box body and a box cover fitted with the box body in a sealed mode. The box cover is provided with at least one ventilating window. Each ventilating window is provided with a ventilating film. The ventilating film is used for regulating and controlling the exchanging rate of air in the box body. The box body and the box cover are sealed to prevent the fact that the air passes through a gap between the box body and the box cover andis exchanged with the outside. The box cover is provided with ventilating windows and each ventilating window is internally provided with a ventilating film. By controlling the exchanging rate of oxygen and carbon dioxide in the preservation box and the outside, inhibition of respiration of fruits and vegetables can be achieved and respiration damages can be prevented, furthermore, self-controlling of the atmosphere inside the preservation box is achieved; and shelf lives of fruits and vegetables are prolonged and the good preservation effect is ensured.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, in particular to a transportation and storage fresh-keeping box. Background technique [0002] Low-temperature refrigeration is an effective means to extend the shelf life of harvested fruits and vegetables, and it is also the only means to preserve the freshness of most fruits and vegetables. It has been widely used in the fruit and vegetable industry, but its effect is difficult to meet the needs of fruit and vegetable circulation and sales. It needs to be combined with other means. Play a synergistic effect with better fresh-keeping effect. [0003] Postharvest respiration of fruits and vegetables is closely related to their shelf life. The stronger the respiration, the faster the quality of fruits and vegetables will deteriorate, and vice versa. The ambient atmosphere of fruits and vegetables has a significant impact on the respiration of fruits and vegetables...
