Anonymous users2024-02-16After the vegetable vacuum packaging machine is wrapped, it is stored at room temperature for a maximum of one week, generally 3-7 days.
Vegetables have been sterilized once before vacuum packaging (source high temperature sterilization, sterilization of sterilants, etc.), then they can be stored for 1-3 months, which depends on different vegetables. Due to the relevant regulations of the state, the pesticide residues of vegetables and so on. Usually non-processed vegetables are kept fresh at low temperatures.
Vegetables used within a week should be cleaned directly and kept fresh by vacuum (but you need to pay attention to the selection before vacuum).
If it is a processed vegetable, it is usually sterilized by high temperature and instantaneous sterilization, sterilized before packaging, and sterilized twice after vacuum packaging, so that it can be stored for half a year.

Anonymous users2024-02-10Summary. Hello, here for you to inquire If only vacuum packaging is used, there is no sterilization and other auxiliary methods, room temperature can generally only be stored for 1-3 days, if assisted by refrigeration, it can generally be stored for a week to a month or so. The main function of food vacuum packaging is to remove oxygen, in order to help prevent food deterioration, its principle is relatively simple, because food mold and deterioration is mainly caused by the activities of microorganisms, and most microorganisms (such as mold and yeast) need oxygen for survival, and vacuum packaging is the use of this principle, the oxygen in the packaging bag and food cells is pumped out, so that microorganisms lose the environment in which they live.

Do you mean that the pressure decrease is that the gauge hand is shifting in the direction of 0, it should be said that the pressure is rising, right? The reason may be that when the gas in the container is pumped out to negative pressure, the temperature of the container will decrease, and the surface of the container will absorb heat during the period of maintaining pressure, and the gas in the container will expand, and the watch hand will shift to the 0 direction.
Negative pressure can be pumped in 15 minutes, and it is clearly written on the manual that the air conditioner must be fully filled for 15 minutes before the air in the air conditioning pipe can be evacuated.
