The packaging workshop is the decisive area for production, and it is the lifeline of food hygiene and safety. Many packaging involves materials that can easily generate static electricity. This is also a tricky issue during the disinfection process. The workshop environment is dry, and such charged packaging articles and packaging equipment are often placed directly. If chlorine dioxide disinfection spray is encountered to dry them into powder fog, even if the probability is small, there will be the possibility of electrostatic ignition.

Once such a disaster occurs, the scrap of the entire production process, not only raw materials, but also the manpower and material resources spent in many work links will turn into a foam, causing considerable economic losses. But please don't panic! The problem of static electricity is easy to avoid, and there is no need to worry too much about disinfection operations. Below is a disinfection trick for you to point out. To avoid some small hidden dangers in food production, it is to put a safety lock on the production.

The first step of prevention: equipment grounding and anti-static design

As the saying goes, in order to do a good job, one must first sharpen their tools. Anti static spray equipment shall be arranged first. By controlling the droplets below 40 μ m, these small particles can reduce the friction and electricity generation between droplets, and also improve the utilization rate of the medication.

Disinfection equipment can be equipped with grounding devices to introduce static electricity into the ground and avoid static interference. Those conductive spray pipelines and nozzles can also be replaced with ordinary anti-static plastic materials. It is better to build and design an equipotential system connection according to the anti-static standard for the application in the whole spray system, so as to prevent trouble before it happens.

There are also some professional devices on the market specifically designed for waterproof electrical control, which have short-circuit, overcurrent, and overload protection functions, which can firmly prevent safety. The prevention and defense intervention of static electricity are reasonable measures to avoid the generation of static electricity, and chlorine dioxide disinfection operations can be easily and worry free implemented.

Second tip for prevention: Optimize atomization parameters and processes

The quality of atomization is also crucial. The size of droplets is a major reason for electrostatic triggering, so it is necessary to ensure that the droplets are small enough, but also to ensure the effectiveness of disinfection. It is necessary to adjust the diameter of the atomized particles appropriately to avoid electrostatic reactions during the disinfection process.

Excessive spray pressure will intensify the friction between droplets and increase the generation of static electricity. Reasonably control the pressure and flow rate of spray. This requirement is based on the actual workshop area, packaging volume and other specific conditions. After selecting the appropriate anti-static equipment, set 10 μ m, 30 μ m, 50 μ m and other atomization modes for spray, subtly adjust the atomization according to the centralized electrostatic area, and select small diameter atomized particles for atomization, so that it can be flexibly handled. Even if the spray lasts for a long time, some electrostatic concentration areas can avoid charge accumulation. Remember to adopt the habit of intermittent spray to fully release the accumulated charge for a period of time before supplementary disinfection.

The third measure of prevention: environmental humidity control and process isolation

Static electricity is difficult to generate in high humidity environments. So the humidity in the packaging workshop can be adjusted to at least 60%, and the items will avoid friction due to surface water mist, which prevents the generation of static electricity.

What should we do if the humidity cannot be directly adjusted in the highly sensitive static areas of the packaging workshop? The direct method is to isolate other movable packaging materials and flammable materials. And standardize the anti-static clothing and footwear requirements for operators, and even standardize some daily work processes for electrostatic protection to avoid it.

The disinfection time should also be planned reasonably, and the intervals during which the production line is suspended should be selected. At this stage, there is no electrical threat to the packaging materials when they are left standing, and disinfection atomization can be quickly released through intermittent operation of the system even if it is rubbed.

The fourth preventive measure: monitoring and emergency response plan

Attention should also be paid to spray in electrostatic sensitive areas: it is necessary to equip electrostatic monitoring equipment. The machine can accurately and timely capture whether the electrostatic potential exceeds the safety threshold, effectively and timely stop spray, and more accurately control the early warning of electrostatic removal in advance.

This operation process requires detailed operating procedures and emergency plans to be designed, and personnel training and operation must meet standardized requirements. Establish a regular awareness of anti-static production, and be able to promptly initiate emergency prevention and control measures when encountering frequent discharges or sparks.

Establishing inspection records for disinfection effectiveness and a review mechanism for safety monitoring not only optimizes the process, but also creates work feedback and enhances production responsibility.

A small reminder:

Before the spray operation, let the equipment spray empty for a few seconds to let the electrostatic ions fall to the ground wire for release, so that by driving away the charge, it will be safer for the formal atomization disinfection.

To summarize:

Chlorine dioxide spray disinfection is a powerful weapon to ensure food safety, but we cannot let it become an "arrow with Mars". Remember the mnemonic: grounding must be present, material must be conductive, environment must be moist, and movements must be meticulous. Although it is a minor hazard, it should be taken seriously enough, which is the cornerstone of stability for production enterprises.
