The plasma is considered to be the fourth state of matter other than solid, liquid and gaseous, and simply the plasma can be considered to be a charged gas in which ions and air collide with each other, causing a series of reactions. The directional movement of energetic particles in the plasma can "break up" bacterial, cellular and viral proteins and destroy the integrity of the genes.
For example, patent application number CN201810412003.4 proposes a plasma sterilizing and packaging mechanism for food processing, which has the technical scheme that the plasma sterilizing and packaging mechanism comprises a frame, wherein a transmission belt is arranged on the top surface of the frame, a plurality of clamping strips are equidistantly arranged on the transmission belt, packaging boxes are arranged between the clamping strips, and food to be processed is placed in the packaging boxes; a sterilizing box, a sterilizing device and a sealing assembly are respectively arranged from the upper part to the left and the right of the transmission belt; the sterilizing device comprises a sterilizing box which is arranged on the upper part of the conveyor belt, a plasma generator is arranged in the sterilizing box, the plasma generator comprises a left generator and a right generator which are arranged in a mutually corresponding mode, the outer sides of the left generator and the right generator are respectively provided with a connector, the two connectors are connected with a power supply, a fan is arranged at the top of the sterilizing box, and an air outlet of the fan faces the plasma generator.

The following is a main body of the gravity index assembly 5 in this example:
the gravity transposition assemblies 5 capable of contacting the positioning seat 4 comprise a material barrel 56 in rolling contact with the positioning seat 4 (one end of the material barrel 56 far away from the sleeve 51 is provided with a friction sleeve 54 in rolling contact with the positioning seat 4), and the sleeve 51 is arranged at one side end of the material barrel 56 and is used for being rotatably connected with the rotating seat 2;
the sleeve 51 and the material bucket 56 are each provided with a plasma channel (the plasma channels in the sleeve 51 and the material bucket 56 are the sleeve inner circulation channel 57 and the material bucket inner circulation channel 53, respectively), and the plasma channels in the sleeve 51 and the material bucket 56 are communicated with each other;
a commutation cell 55 is rotatably arranged in the sleeve 51, wherein the commutation cell 55 is only rotated in a single direction in the sleeve 51 for guiding the plasma along a plasma channel in the sleeve 51 and in the material barrel 56 into the material barrel 56 or from within the commutation cell 55 into the material barrel 56 when the material barrel 56 is located above or below the sleeve 51.
Referring to fig. 1-7, in this embodiment, a food sterilization apparatus is provided, which is capable of comprehensively sterilizing food during rotation, and combines a speed-adjusting motor 1, a rotating base 2, a positioning base 4, a plurality of gravity transposition assemblies 5, a plasma generator 7 and other components, so as to place the food in the plurality of gravity transposition assemblies 5, and adjust the prescribed positions of the plurality of gravity transposition assemblies 5 during rotation of the speed-adjusting motor 1 driving the rotating base 2 compared with the positioning base 4, namely, the process of comprehensively sterilizing the food;
in the following, in connection with the subdivision structure of the gravity transposition assembly 5, a description is given of how the gravity transposition assembly 5 performs a complete sterilization:
(1) the combination of the material bucket 56 and the sleeve 51 can only rotate in the up-down direction relative to the rotary seat 2, so that the position of the combination at the rotary seat 2 is always in a conversion state;
(2) referring to fig. 6, when the material barrel 56 is located above the sleeve 51, the filled plasma in the rotating seat 2 is guided into the material barrel 56 along the plasma channels in the sleeve 51 and the material barrel 56 to sterilize the surface of the food far from the sleeve 51;
(3) referring to fig. 7, when the material barrel 56 is located below the sleeve 51, the plasma is directly introduced into the material barrel 56 from the inside of the converter unit 55, and the surface of one side of the food contacting the material barrel 56 is sterilized, so that the food is sterilized completely after one rotation.
Hereinafter, by providing a plurality of implementation processes, the impeller 52, the converter unit 55, and the remaining mating components in this example will be described in detail:
in particular, the sleeve 51 extends into the rotary seat 2, and the impeller 52 is mounted at the end of the sleeve 51 extending inwards, so that when the material barrel 56 is in rolling contact with the positioning seat 4, the plasma in the rotary seat 2 enters the sleeve 51, and it is required to be clear that the converter unit 55 is located between the material barrel 56 and the impeller 52.
As shown in the figure, the sleeve 51 and the material barrel 56 are combined, based on this, when the friction sleeve 54 at the material barrel 56 is in rolling contact with the positioning seat 4, the impeller 52 arranged at the extending end of the sleeve 51 can generate air flow flowing in the sleeve 51 from the inside of the rotating seat 2 when the friction sleeve 54 is in rolling contact with the positioning seat 4, namely, the air flow promotes plasma to enter the combined body, so that the food placed in the material barrel 56 is subjected to comprehensive sterilization treatment.

As shown in fig. 4, 6 and 7, the converter unit 55 is an adjusting device for adjusting the flow path of the plasma, and the adjusting mechanism of the adjusting device is gravity, that is, a counterweight 554 disposed in the spherical shell 553, so that the spherical shell 553 can always maintain the set position, that is, the spherical shell 553 rotates relative to the sleeve 51, which is understood as the sleeve 51 rotates relative to the spherical shell 553;
based on this, referring to fig. 4 and 6, when the material barrel 56 is located above the sleeve 51 (food is covered at the other port of the sleeve 51), the interface 551 is connected with the intra-sleeve flow channel 57 provided in the sleeve 51, and after the connection, plasma enters the material barrel 56 along the intra-sleeve flow channel of the sleeve 51 and the material barrel 56, and plasma sterilization treatment is performed on the surface which is not contacted with the barrel bottom of the material barrel 56;
referring to fig. 4 and 7, when the material barrel 56 is located below the sleeve 51 (the food is not covered on the other port of the sleeve 51), the interface 551 is dislocated and closed with the intra-sleeve flow channel 57 provided in the sleeve 51, and after the connection, the plasma directly enters the material barrel 56 from the straight discharge port 552, and the surface contacting the bottom of the material barrel 56 is subjected to plasma sterilization treatment;
in combination with the above, the relative position of the converter unit 55 can be in a changed state to adjust the plasma inlet path to perform the overall plasma sterilization treatment on the food.
In particular embodiments, a cover 3 is embedded in an end port of the material bucket 56 remote from the sleeve 51, the cover 3 being adapted to support material when the material bucket 56 is positioned below the sleeve 51.
As shown in fig. 7, when the material barrel 56 is located below the sleeve 51, the food is at risk of being separated outwards relative to the material barrel 56 under the action of gravity, so that the falling food is supported by installing the cover plate 6 at the port of the material barrel 56, and the separation phenomenon can be effectively avoided.
In a specific implementation, the cover plate 6 is installed at one end of the rotating seat 2 far away from the positioning seat 4, the cover plate 6 is a fixing part of the plasma generator 7, wherein the plasma generator 7 comprises a fan 71 fixed at the cover plate 6 and a shield 74 arranged in the rotating seat 2, a plurality of overflow grooves 72 are formed in the side wall of the shield 74, a plasma generating unit 73 is further installed in the shield 74, and the plasma generating unit 73 and the fan 71 are electrically connected with a power supply.
As shown in fig. 5, the plasma generating unit 73 generates plasma, and then the blower 71 allows the plasma to overflow from the overflow tank 72 by blowing air into the shield 74.
