Along with the change of air temperature, the frozen cold chain product is not only a frozen cold chain product, but also the external packages of fresh livestock meat, aquatic products and raw materials become natural cold chains under the natural air temperature, and the assembly line, the consignment of luggage cases and the sorting of express items all need to be disinfected and sterilized.

Currently, common methods for sterilizing the surface of the box include: ultraviolet sterilization, ozone sterilization, chemical agent sterilization, and the like, while for large batches of food, goods, and packaging flows, a rapid and efficient sterilization mode is required.

As for the mode of disinfection and sterilization by chemical disinfection liquid, the mode of spraying is usually adopted, and the method has the advantages of high speed and short time for realizing disinfection and sterilization, but also has the following disadvantages:

first, this method can not accomplish six disinfection and sterilization completely, the form of spraying, and the bottom of cold chain goods does not accomplish to spray evenly, and therefore the disinfection and sterilization that brings is not enough, and adopts tilting mechanism to carry out 180 degrees upset disinfection and sterilization, and the disinfection and sterilization of upper and lower two sides can be guaranteed, but the disinfection and sterilization of its side is not enough, and adopts six upset disinfection and sterilization, and the time overlength of single disinfection and sterilization influences disinfection and sterilization efficiency.

Second, icing easily occurs. The temperature of the cold chain commodity is very low, and the disinfection and sterilization substance sprayed on the surface is easy to freeze, so that the effectiveness of the disinfection and sterilization substance is influenced.

And thirdly, the spray nozzle is blocked, and the spray type disinfection and sterilization is realized by the principle that a high-pressure pump is matched with the spray nozzle with a tiny hole to generate tiny water drops. Therefore, the head is very easily clogged. And further cause damage to the pump head and even accidents.

The work flow of the scheme comprises the following steps:

when the box just enters the irradiation area of the downward electron beam emitter, the middle electron beams which are not shielded by the upper surface of the box perform irradiation disinfection and sterilization treatment on the front surface and the upper surface of the box, and the electron beams at the two ends are deflected by the deflection magnets at the two sides to perform irradiation disinfection and sterilization treatment on the front surface and the side surface of the box. After the front surface of the box passes through the irradiation area, the electron beams in the middle part irradiate the upper surface of the box for sterilization, and the electron beams at the two ends are deflected by the deflection magnet and then irradiate the side surface of the box to treat the side surface. When the side surface of the box leaves the irradiation area, the electron beams deflected at the two ends start to irradiate the back surface of the box, and the electron beams which are not shielded by the box in the middle simultaneously irradiate the back surface until the back surface completely leaves the irradiation area.

a fourth electrical or pneumatic push rod (not shown) is provided within the exit shield to push the cassette away from the exit shield. With this configuration, the cassette is moved into and out of the irradiation chamber: when the box runs to a preset position away from the first shielding door at the inlet of the irradiation cavity, the two shielding doors are in a completely closed state, then the shielding doors are quickly opened, the box is quickly pushed to the preset position between the two shielding doors by a push rod mechanism, the speed of pushing the box by the push rod is far faster than the normal running speed of the box, then the first shielding door is quickly closed, the second shielding door is opened, then the box is quickly pushed to the preset position of the irradiation cavity by the other push rod, and at the moment, the second shielding door is quickly closed to prepare for the next box to enter; the box which enters the irradiation cavity is transported by the transmission roller to enter the irradiation area, and all surfaces are irradiated. After the irradiation treatment is finished, the same process as that of the inlet is finished through the same double-shielding door channel of the outlet of the irradiation cavity, the irradiation cavity is reached to the outside of the irradiation cavity and is transmitted to the next procedure by an external transmission mechanism, the electric or pneumatic push rod adopting the scheme is only used for ensuring the transmission rate of the electric or pneumatic push rod, the mode of a roller or a conveyor belt on the transmission assembly is directly adopted instead of the mode, the input and output effects can be achieved as well, and only the transmission rate is influenced by the rate of the transmission assembly.

In the scheme, the box is quickly pushed to pass through the double-shielding door channel through the electric or pneumatic push rod, so that the duty ratio of the box in an irradiation area is effectively increased, the utilization rate of electron beams is improved, and the productivity is improved. (for example: if the same speed as the irradiation area is adopted, it is assumed that 12 m/min, 1 s advances 0.2 m, the box passes through the double screen door at the constant speed, the screen door is opened, the time consumption is set to be 1 s, the screen door is closed for 1 s, the length of the box is 1 m, the space between the boxes is at least 1.8 m, the duty ratio is 1/2.8 is 35.7%, the mode of a quick push rod is adopted, it is assumed that the box is pushed to the preset position, the time consumption is 1 s for one time, the box needs to be pushed twice through the double screen door channel, the time consumption is 2s, the time consumption is 1 s for opening the first screen door, the time consumption is 1 s for closing, the time consumption is 2s for opening and closing the second screen door, the time consumption is 6 s for the box to pass through the double screen door channel at a constant speed, which is equivalent to the length of 1.2 m, the box space only needs 0.2 m to realize the continuous pass through the double screen door channel, the duty ratio is 1/1.2 ═ 83%, improved by 2.33 times compared with the constant speed operation).

In another example, the electron beam emitter is configured to adopt any one of a scanning mode or a long filament mode, and the deflection magnet is configured to adopt any one of a permanent magnet or an electromagnet, in which the scheme can be selected according to different application scenes and application requirements, so that the scheme has better adaptability.

In another example, as shown in fig. 6, the length of the ribbon beam is configured to be the width required by two boxes side by side plus the spacing between the deflection magnet and the transmission assembly, in this arrangement, the length of the ribbon beam emitted by the electron beam emitter exceeds the width of two square boxes side by side plus the predetermined spacing between the boxes and the predetermined distance left outside the two boxes respectively, the excess beam exceeding the upper surface portion of the boxes continues to fly downward, and passes through the deflection magnets disposed on both sides of each box, and is pushed toward the side surface of the respective box by the magnetic field of the deflection magnets, thereby performing radiation sterilization on the side surface of each box. The magnetic field distribution of the deflection magnets enables the electron beam deflection angles on both sides to cover at least the majority of the area of the lateral surface of the box that exceeds the midline, and after the box is turned over, the lower half of this lateral surface becomes the upper half, so that six surfaces of the whole box can be completely covered by two times of irradiation.

In another example, each deflection magnet is installed on two sides of the transmission assembly through matched telescopic pieces (not shown) in space, the telescopic machine can fix the motor on the installation frame of the transmission assembly through the installation piece, then the horizontal distance between the deflection magnet and the box is adjusted by matching with the screw rod and the sleeve, so that the irradiation requirements of boxes with different widths can be met, another motor can be fixed on the ground of the irradiation chamber through the installation seat, the other set of screw rod and the sleeve which are matched with each other are connected with the installation piece, and the longitudinal position adjustment is further achieved, so that the irradiation requirements of different heights can be met. In this solution, the relative position of the side and the deflection magnet is kept constant, with reference to a predetermined position in the middle of the electron beam emitter, for boxes with non-uniform lateral dimensions. The deflecting magnets at both ends of the electron beam emitter are designed to be movable to a position spaced apart from the side surface of the cartridge by a predetermined distance according to the width of the cartridge, thereby ensuring that the deflecting electron beams can effectively irradiate the side surface of the cartridge.

Of course, for the boxes with different heights, the height of the box is preferably adjusted (the height of the electron beam emitter can also be adjusted), and the distance between the surface of the box and the lead-out window of the electron beam emitter is kept consistent.
