2. Background technology:

my country is a large agricultural country, and the output of grain is huge. If it is not stored well, it will deteriorate. Among them, the safe long-term high-quality storage of grain requires three elements: 1. Reasonable and safe moisture: the general moisture content is 14% (depending on the variety and region) There are some differences), higher than this safe moisture content, grains are prone to mildew, and the lower the moisture content, the better for long-term storage. Every 1% reduction in moisture content can prolong the storage life by 1-3 years. 2. Appropriate storage temperature: the lower the temperature, the better, because the oxidation of grains will be accelerated under high temperature, and the pests and diseases will also intensify. 3. Appropriate oxygen partial pressure: The lower the oxygen partial pressure, the better the effect of killing insect pests and inhibiting the growth of microorganisms, which can slow down the oxidation and decomposition of grain nutrients and maintain the original quality of grain. In response to this situation, people need to dry the grain before storing it, so that the grain reaches a certain moisture level before storing it. Under high ambient temperature, artificial low-temperature ventilation and cooling are used to keep the stored grain at a suitable temperature. For pests and diseases, use drug fumigation to eliminate pests, mainly chemical substances such as phosphine (or aluminum phosphide) and methyl bromide. The control effect is poor, and it will bring 3R problems (increased resistance, drug residue, rampant growth), food safety and ecological environment problems.

Chinese patent (authorized announcement number is CN1316880C, and patent number is 200410053958.3) discloses a kind of " disinfestation device and using method thereof for storing food service ", and its device comprises: A, pressure-resistant container W (made by metal or plastics ), a material inlet and outlet and an additional sealing door cover 2 are respectively arranged at its top and bottom; B. the pipe connection J1 of the pressure-relief valve 1 is arranged on the top of the pressure-resistant container W and the gas transmission and pressurization gas source mechanism (by the compressor or nitrogen cylinder constitutes) the pipe connection J2 of the air supply valve 5; its method of use steps include: A, before the grain enters the warehouse for storage, they are put into the pressure-resistant container by the upper conveyor belt mechanism 3 in batches to carry out pressure-changing extinguishing Insect treatment (pressurization through a high-pressure air source and then rapid depressurization) forces the soft tissues inside the shells of insects (including eggs and pupae) to burst or swell to death. B. Afterwards, take out the deinsectized grains from the pressure-resistant container W and transport them through the lower conveyor belt mechanism 3 and store them in the grain warehouse. It adopts pressure-changing deinsectization, has no drug residues, and is environmentally friendly, but it is only An extermination measure before grain storage cannot guarantee other conditions of grain storage, and the pressure-resistant container is used, the manufacturing cost is relatively high, and the long-term high-quality storage of grain cannot be achieved.
