大気雰囲気のパッケージングの鍵
改良された雰囲気のパッケージを取得するための鍵:
ガス置換精度の高い包装機をお選びください
いわゆるガス交換は、梱包箱内のすべての空気を排出し、一定の割合で混合された新鮮なガスを再充填してガス交換を完了することです。現在、市場にある修飾された雰囲気のパッケージング装置のガス交換には、完全密閉の真空置換タイプと気流精練タイプの2つの方法があります。
The principle of fully enclosed vacuum replacement is to put the tray with food in an absolutely closed vacuum chamber, use a vacuum pump (or high oxygen vacuum pump) to evacuate the air in the vacuum chamber, so that the vacuum chamber reaches a certain degree of vacuum, and then fill and mix Keep the gas fresh and seal it to complete the process of gas replacement. This form of gas replacement can make the residual oxygen content in the vacuum chamber less than 1%, ensuring the highest accuracy of the fresh gas filled.
The principle of air flow scouring compensation gas replacement is to use the negative pressure generated by the vacuum generator to extract the air in the tray. While tracing the air, the tray container is continuously filled with a large amount of fresh gas and then sealed. This kind of gas replacement method has high residual oxygen content in the package (the original air in the package cannot always be cleaned), which makes the accuracy of the proportion of fresh gas in each package ununiform, resulting in a serious problem of uncontrolled shelf life of meat food. The equipment using the airflow scour compensation type consumes a large amount of gas during the gas replacement process, and the packaging cost is high.
結論:完全に密閉された直接空気置換技術は、何年にもわたる実験を繰り返した後、ヨーロッパとアメリカの関連する研究機関によって要約された最も効果的な構造形式です。このフォームは、混合されたフレッシュキーピングガスの高い交換率を保証し、食品保存の効果を真に達成することができます。
