The working principle of the cow small row box type air lock lock fresh packaging machine:

Fresh raw steaks will lose nutrients and taste will change. How to extend the shelf life of the steaks without losing nutrients, the taste will not change, this requires a modified atmosphere packaging machine, Meikang vacuum The packaging machine solves the problem that the raw meat is not refrigerated and stored, and the shelf life of the product itself is prolonged, and the taste does not change. Next, we will introduce how the box-type modified atmosphere packaging machine can extend the product shelf life and the nutrients are not lost.

Meikang cattle small row box type air lock lock fresh packaging machine works:

The box type air conditioning fresh-keeping packaging machine is a brand-new food and vegetable fresh-keeping packaging equipment developed on the basis of vacuum packaging machine and nitrogen filling packaging machine. The biggest feature is that it solves the problem that the taste of food is greatly damaged after vacuum packaging and high temperature sterilization, and the nitrogen-filled packaging requires aseptic packaging and the investment is large. Through the combination of modified atmosphere packaging, it can ensure the original nutrition, taste and taste of the food, and ensure the original taste and original appearance of the food. The box type vacuum inflatable packaging machine comprises a frame, a box conveying mechanism arranged on the frame, a film cutting mechanism, a film conveying mechanism and a heat sealing mechanism, and the box type vacuum packaging machine further comprises a vacuum chamber and a vacuum on the frame A vacuum pump connected to the chamber, the vacuum pump being located below the vacuum chamber. The vacuum chamber includes an upper vacuum chamber and a lower vacuum chamber. The upper vacuum chamber and the lower vacuum chamber are axially and relatively movable on the guide post. The heat sealing mechanism is disposed in the upper vacuum chamber, and the storage mechanism is disposed in the lower vacuum chamber. . The whole frame body is made of SUS304 stainless steel, which is hygienic and environmentally friendly. Does not rust, does not oxidize.

The working principle of the cow small row box type air-conditioning lock fresh packaging machine: qualified air-conditioning fresh-keeping packaging machine, there are two key technical indicators must meet the corresponding requirements, the two major indicators are: First, the gas replacement rate is high, Second, the gas mixing accuracy error rate is low. Whether the quality of the composite gas-conditioning fresh-keeping packaging equipment is qualified or not needs to be judged by these two key indicators. Modified atmosphere gas is generally composed of carbon dioxide (CO2), nitrogen (N2), oxygen (O2) and a small amount of special gases. Carbon dioxide has the effect of inhibiting the growth and reproduction of most bacteria and molds, slowing down the metabolism of fresh fruits and vegetables, and is the main antibacterial component in fresh-keeping gas. Oxygen inhibits the growth of most anaerobic bacteria, maintains fresh color and maintains aerobic respiration of fresh fruits and vegetables. It maintains the freshness; nitrogen is an inert gas that does not work with food. As a filling gas, it is a composite gas with carbon dioxide, oxygen and special gases. The composition and proportion of fresh food gas required for different foods, fruits and vegetables are also different.
