Embodiment

[0011] When the harvest season of lychee and longan comes, drive the car with the integrated box to the field. Connect the power supply and start blowing on the spot in the box. First, put the PET preform into the hole oven for heating. Control the bottom temperature to 104°C, the middle temperature to 106°C, and the upper temperature to 108°C. After heating, it enters the blow molding machine. Blow the bottle under the condition of kilogram air pressure, pour the blown bottle into clean water and cover the lid, put it in the quick freezer for quick freezing, put it in the freezer after the water freezes, put the polyethylene plastic bag into the foam packaging box, put The purchased lychee or longan is picked clean, packed in a plastic bag, put into an ice bottle, put into a box, and then evacuated by a vacuum machine to a vacuum degree of -500mmHg, and then injected into a nitrogen machine while evacuating. Nitrogen gas is injected into 0.23m3 nitrogen once per box containin...

Abstract

An antistaling method for the container of fruit, vegetables, fresh flower and agricultural by-products includes such steps as blowing bottles, filling water in the bottles, quickly freezing to become ice bottles, loading the products and said ice bottles in bags, vacuumizing it while filling nitrogen gas, sealing and loading the bags in container. Its advantages are long antistaling time (30-60 days), and easy operation.

Description

Technical field: [0001] The invention relates to a method for preserving fruits, vegetables, fresh flowers, agricultural and sideline products, etc., in particular to a method for preserving freshness of an integrated box under a nitrogen-containing vacuum state. Background technique: [0002] At present, the fresh-keeping technology market adopts the method of refrigeration in the process of circulation and storage. Although it can achieve a certain degree of fresh-keeping, it has many shortcomings. Faster transportation such as air transportation cannot achieve the goal of satisfactory fresh-keeping. However, for various agricultural and sideline products that cannot be refrigerated (they will go bad once frozen), there is a lack of good fresh-keeping methods, so that a large amount of agricultural and sideline products cannot be transported over long distances, which not only affects the enthusiasm of farmers for production, but also cannot satisfy the market. demand. I...
