Description

Emergency survival tank and packaging method thereof Technical Field The invention relates to the technical field of food storage, in particular to an emergency survival tank and a packaging method thereof. Background Emergency survival equipment is a key material for dealing with natural disasters, wild quests and emergent public events, wherein the long-term reliable storage of compressed foods and survival tools is directly related to the life safety of users. An ideal emergency survival can would have the ability to keep food stable in quality, tool function intact for 3 to 5 years, and even longer, under harsh environments without the need for a cold chain, without power supply. However, the existing food storage tank technology has a remarkable technical bottleneck in achieving the long-period fresh-keeping aim, and is characterized in that most storage tanks at present adopt simple sealing structures, the fresh-keeping period of foods which are stable in materials and difficult to oxidize can reach 3 to 5 years, but the fresh-keeping effect of the structure is obviously reduced for foods which are rich in peanut oil, sunflower seed oil and other easily-oxidized components, and can be maintained for only 1 to 2 years generally. Although the prior art attempts to isolate oxygen by combining nitrogen filling with heat sealing of aluminum foil, this method only extends the shelf life by about 1 year compared to conventional sealing methods, and it is still difficult to meet the storage requirements for periods of 3 to 5 years or even longer. Disclosure of Invention The invention provides an emergency survival tank and a packaging method thereof, which are used for solving the problem that the existing food storage tank is isolated from oxygen by adopting a nitrogen filling and aluminum foil heat sealing mode, and the storage tank can not meet the requirement that the storage tank has a storage life of 3-5 years. In a first aspect, the present invention provides a method for packaging an emergency survival tank, the emergency survival tank including a tank body and a cover body adapted to an open end of the tank body, the method comprising the steps of: Placing the compressed food and survival tool assembly in the cavity of the tank body and placing the tank body in a vacuum chamber; performing vacuumizing operation on the cavity containing the compressed food and the survival tool component until the cavity reaches a preset negative pressure state; when the cavity reaches a preset negative pressure state, filling inert gas and/or protective gas into the cavity until the gas environment in the cavity is formed into a preset gas environment; the cover body is sealed at the opening end of the tank body, so that a closed space for maintaining the gas environment is formed in the cavity. Under the condition of adopting the technical scheme, the operation of vacuumizing and filling inert gas and/or protective gas into the vacuum chamber at least once can enable the gas environment in the cavity to reach the preset gas environment, so that the food fresh-keeping period in the preset gas environment can meet the requirement that the emergency survival tank needs 3-5 years. In an alternative embodiment, the preset negative pressure state includes a preset first air pressure threshold, and the step of performing a vacuum operation on the cavity containing the compressed food and survival tool assembly until the cavity reaches the preset negative pressure state includes: acquiring a first air pressure value in the cavity; and stopping the vacuumizing operation and maintaining the current negative pressure state of the cavity when the air pressure value is reduced to be equal to or lower than a preset first air pressure threshold value. In an alternative embodiment, the preset gas environment includes a preset second air pressure threshold value and a preset oxygen concentration threshold value, and when the cavity reaches a preset negative pressure state, inert gas and/or protective gas is filled into the cavity until the gas environment in the cavity is formed into the preset gas environment, the step of forming the preset gas environment includes: injecting inert gas and/or protective gas into the cavity; acquiring a second air pressure value in the cavity; when the second air pressure reaches a preset second air pressure threshold value, acquiring the oxygen concentration in the cavity; And if the oxygen concentration is higher than the preset concentration threshold, repeating the vacuumizing operation and the inert gas and/or protective gas filling operation in sequence until the oxygen concentration in the cavity is equal to or lower than the preset oxygen concentration threshold. In an alternative embodiment, the cover body is a primary-secondary cover, and the primary-secondary cover includes an outer cover and an inner cover, until after the step of forming the gas environment in the cavity into a preset g
