Problems solved by technology

[0003] 1) Taking edible oil as an example, since the oxygen in the air in the tank before nitrogen filling cannot be completely removed by vacuuming, if nitrogen is directly filled, there will be more residual oxygen, and the oxidation of edible oil in the tank can only be limited to suppress, resulting in poor oil quality. Continuous decline
[0004] 2) The traditional technology is aerobic nitrogen filling and driving away oxygen with inert gas. Because homogeneous and compatible, it belongs to limited dilution. After oxygen driving, the oxygen content in the container is still very high
[0005] 3) The traditional process of flattening the container to drive oxygen can be used for soft containers such as small plastic bags, but large and rigid metal cans and other containers cannot be used by the method of "container flattening and driving oxygen"
[0009] Due to the traditional technology of aerobic nitrogen filling and offline isolation, there is more residual oxygen-containing air in the packaging container

Embodiment

[0017] 200m 3 Fruit juice zero-oxygen liquid storage device and liquid storage process, such as figure 1 :

[0018] 1. Raw materials and equipment

[0019] Raw material: juice

[0020] Equipment: zero-oxygen liquid storage device, inert gas source, inert gas balance device (small inert gas bag).

[0021] 2. Process flow and implementation instructions (such as figure 1 )

[0022] The liquid storage device uses a large amount of inert gas, but the structure is simple and easy to use. The process is implemented as follows:

[0023] (1) The reversing valve is set to lead to the exhaust port 5, the liquid discharge port 6 is closed, and the infusion valve at the front end of the infusion catheter 1 is opened, so that the fruit juice enters the inner cavity 7 of the liquid storage tank through the 1 .

[0024] (2) The liquid / air interface in the tank rises with the input of juice from the infusion conduit 1, and the oxygen-containing air in the tank is discharged from the ex...

Abstract

A zero-oxygen packed liquid food features that its producing and packing procedure, a heterophase interface oxygen-expelling system is used for expelling all oxygen-contained air from liquid food and packing container. The heterophase interface oxygen-expelling system and its zero-oxygen liquid storage, zero-oxygen pouring machine and zero-oxygen packing container are also disclosed.

Description

technical field [0001] The invention discloses an interface deoxygenation process content for liquid food production and packaging. In particular, it discloses a zero-oxygen liquid storage device configured for an interface oxygen driving process. Background technique [0002] At present, in addition to the addition of antioxidants, the measures adopted in the process of processing, storage and transportation, and packaging of liquid food also adopt an inert gas (anoxic) protection method. The traditional technology specifically has the following deficiencies: [0003] 1) Taking edible oil as an example, since the oxygen in the air in the tank before nitrogen filling cannot be completely removed by vacuuming, if nitrogen is directly filled, there will be more residual oxygen, and the oxidation of edible oil in the tank can only be limited to suppress, resulting in oil quality Continuous decline. [0004] 2) The traditional technology is aerobic and nitrogen filling, and i...
