Embodiment 1

[0017] The packaging box is formed by sequentially connecting a box cover part, a drainage layer part and a water storage layer part, and each part is connected by a spiral detachable. Wherein the lid 1 is a hollow cylinder without the bottom surface, and the top surface of the lid 1 is provided with a storage box 2 with a cover and an air vent 3; A hollow cylindrical antistaling agent storage cavity 7 with a layer diameter and a height higher than that of the draining layer is removed. The side of the antistaling agent storage cavity 7 is provided with axially and radially evenly distributed small holes, and the outer wall of the preservative storage cavity 7 reaches the draining layer. Rectangular dividing plate A4, dividing plate B5 and dividing plate C6 are arranged between 8 side inner walls, the three spaces that three dividing plates form are identical, and several draining holes 9 are provided on the bottom surface of draining layer 8; Hollow cylindrical.

Embodiment 2

[0019] This embodiment provides a fresh-cut fruit and vegetable fresh-keeping packaging box, and the material of the packaging box is food-grade polypropylene. Lid 1 is spirally connected with drain layer 8. A circular ventilation hole 3 with a diameter of 5mm is provided on the box cover 1, and a plug is provided on the ventilation hole. The ventilation hole 3 is used to control the gas environment in the fresh-cut fruit and vegetable packaging box. The lid 1 is also provided with a storage box 2 with a lid, and a fruit fork or toothpick, paper towel, etc. can be placed in the storage box 2 with a lid, which is convenient for taking fresh-cut fruits and vegetables, and put them into the box after use to avoid fruit fork pollution.

[0020] Partition board A, partition board B and partition board C and the preservative storage chamber 7 divide the drainage layer 8 into four partitions, of which three larger partitions with the same area are used to hold three different fresh-...

Embodiment 3

[0022] First, add an appropriate amount of fruit-specific preservative to the dry preservative storage cavity 7, put the processed apples, cantaloupe, and dragon fruit into 8°C water for cleaning, and divide the three kinds of fruits into the three separate areas of the draining layer 8 Quickly connect the water storage layer 10 after draining too much water; cover the lid 1, put small forks, paper towels and salad dressing in the storage box with lid 2, and plug the air hole 3 plugs tightly; put the packaged fresh The temperature for cut fruits and vegetables to be stored is 0-4°C for cold chain transportation or direct sales. If the sales time is too long, the ventilation holes can be opened for 1-2 minutes.

Abstract

The invention discloses a fresh-cut fruit and vegetable fresh-keeping packaging box and a fresh-keeping method thereof, and belongs to the technical field of fruit and vegetable fresh-keeping. The fresh-keeping box is a cylinder-like body and is formed by sequentially connecting a box cover part, a draining layer part and a water storage layer part in a threaded manner, the top surface of the boxcover is provided with a storage box with a cover and a vent hole, a preservative storage cavity is formed in the center of the draining layer, small holes are formed in the surface of the storage cavity, the space between the draining layer side surface and the preservative storage cavity is averagely divided into three same areas by the partition board A, a partition board B and a partition board C, and draining holes are formed in the bottom surface of the draining layer. The fresh-keeping method comprises the following steps of putting the processed fresh-cut fruits and vegetables into water at 8 DEG C to be cleaned; then placing the mixture into the draining layer of the packaging box for standing for 5-7 minutes, and then connecting the draining layer with the water storage layer; covering the box cover, and enabling the packaged fresh-cut fruits and vegetables to enter a cold chain to be transported or directly sold. The fresh-cut fruit and vegetable fresh-keeping packaging boxcan be used for containing fruits and vegetables of different types, and the packaging box is attractive in appearance, simple in structure, safe and easy to obtain material and convenient to carry.

Description

technical field [0001] A fresh-cut fruit and vegetable fresh-keeping packaging box and a fresh-keeping method thereof belong to the technical field of fruit and vegetable fresh-keeping.
