Introduction: food factory safety challenges and explosion-proof indicator lamps inevitable choice<\/strong><\/strong><\/h2>\n\n\n\n

Food factory as involving raw materials processing, high temperature sterilization, cleaning and disinfection and other aspects of industrial scenarios, the long-term face of flour dust, alcohol vapors, ammonia leakage and other explosive environmental risks.<\/p>\n\n\n\n

Ordinary lighting equipment in the dust-rich or flammable gas environment, probably due to electric sparks or high temperature surface triggering serious accidents.<\/p>\n\n\n\n

Explosion proof led exit sign with its professional explosion-proof certification, corrosion-resistant design and emergency indication function, into a food factory lighting system core safety equipment.<\/p>\n\n\n\n

In this paper, we will start from the special risk of food factories, analysis of explosion-proof indicator application value, technical guidelines and implementation strategies for the supply of safe and efficient lighting for enterprises to handle the program.<\/p>\n\n\n\n

1. the primary safety hazards in food factories<\/strong><\/strong><\/h3>\n\n\n\n

Combustible dust environment: flour, starch processing area dust concentration \u2265 40g\/m\u00b3, when the ignition source [such as static spark] can trigger an explosion [MIT \u2265 380 \u2103]. Milk powder, powdered sugar packaging line dust cloud explosion lower limit [MEC] as low as 30g\/m\u00b3.<\/p>\n\n\n\n

Combustible gases and vapors: alcohol sterilization area [such as 75% ethanol] vapor explosion limit 3.3%-19%. Leakage of ammonia refrigerant in cold rooms [MEC 15%-28%].<\/p>\n\n\n\n

Corrosive cleaning environment: CIP [in-situ cleaning] system using strong acid [pH 1], strong alkali [pH 14] solution, accelerating the corrosion of ordinary lamps and lanterns.<\/p>\n\n\n\n

2. Explosion proof led exit sign safety protection mechanism<\/strong><\/strong><\/h3>\n\n\n\n

Explosion-proof indicator approved the following technologies to implement intrinsic safety:<\/strong><\/strong><\/h4>\n\n\n\n

Dust and gas double explosion-proof design:<\/p>\n\n\n\n

Ex tD certification [dust explosion-proof]: IP6X fully sealed shell, surface temperature \u2264 120 \u2103 [T5 group], to prevent dust intrusion and overheating ignition.<\/p>\n\n\n\n

Ex d certification [gas explosion-proof]: die-cast aluminum shell explosion-proof chamber, suitable for alcohol vapors and other Zone 1 areas.<\/p>\n\n\n\n

Corrosion-resistant and food-grade materials: 316 stainless steel housing or food-grade polycarbonate [FDA compliant], resistant to acid and alkali detergents.<\/p>\n\n\n\n

Intelligent emergency function: switch to lithium iron phosphate battery within 0.5 seconds after the main power supply is interrupted, supplying \u2265180 minutes of continuous lighting [in line with GB 17945-2010 guidelines].<\/p>\n\n\n\n

Second. <\/strong>Explosion proof led exit sign<\/strong> in the food factory core application scenarios<\/strong><\/strong><\/h2>\n\n\n\n

1. Raw material handling and processing area<\/strong><\/strong><\/h3>\n\n\n\n

Flour sieving and mixing equipment: install Explosion proof exit sign on the top of the sifter and mixing tank, and authorize red\/yellow lights to warn of excessive dust concentration or equipment overload.<\/p>\n\n\n\n

Frying and drying line: use T4 group Explosion proof exit sign [surface temperature \u2264135\u2103] in high temperature area [\u226580\u2103] to prevent flash explosion of grease vapor.<\/p>\n\n\n\n

2. cleaning and disinfection and packaging area<\/strong><\/strong><\/h3>\n\n\n\n

Alcohol sterilization workshop: Explosion proof led exit sign integrated gas sensor, alcohol vapor concentration \u2265 20% LEL triggered sound and light alarm and linkage exhaust system.<\/p>\n\n\n\n

Aseptic packaging line: IP69K protection level explosion-proof indicator, resistant to 80 \u2103 autoclave sterilization, to ensure that the clean room lighting without dead ends.<\/p>\n\n\n\n

3. Cold chain and storage area<\/strong><\/strong><\/h3>\n\n\n\n

Ammonia refrigeration plant room: Explosion proof led exit sign is equipped with ammonia detection module, which activates emergency evacuation guidelines and closes refrigeration valves synchronously when the concentration is \u226550ppm.<\/p>\n\n\n\n

Low-temperature cold storage: -40 \u2103 special explosion-proof indicator built-in battery heating module, to ensure that the extreme environment of the emergency function is normally activated.<\/p>\n\n\n\n

Third, the food factory explosion-proof indicator selection and technical guidelines<\/strong><\/strong><\/h2>\n\n\n\n

1. Certification and compliance requirements<\/strong><\/strong><\/h3>\n\n\n\n

Dual explosion-proof certification: ATEX [II 2D Ex tD A21 IP6X T135\u2103 \/ II 2G Ex d IIC T4 Gb] or IECEx certification<\/a> needs to be approved at the same time, to adapt to the dust and gas mixed hazardous environment.<\/p>\n\n\n\n

Food contact safety: The surface material of the luminaire should comply with EC1935\/2004 food grade guideline to avoid contamination by cleaning agent residue.<\/p>\n\n\n\n

2. Fundamental technical parameters<\/strong><\/strong><\/h3>\n\n\n\n

Light source performance: LED light source luminous efficiency \u2265 140lm \/ W, color temperature 4000K [natural white], color rendering index Ra> 90, accurate identification of food color and foreign matter.<\/p>\n\n\n\n

Protection level: clean area needs IP69K [high pressure and high temperature rinsing], general area at least IP66.<\/p>\n\n\n\n

3. Intelligent function upgrade<\/strong><\/strong><\/h3>\n\n\n\n

IoT Integration: RS485 or LoRaWAN protocol is approved to access the factory MES system to monitor the status of lamps, battery health and environmental data in real time.<\/p>\n\n\n\n

Human-computer interaction design: touch-screen control panel to hold help multi-language switching, a key to trigger the emergency drill mode.<\/p>\n\n\n\n

Fourth, Explosion proof led exit sign<\/strong> <\/strong>installation and maintenance specifications<\/strong><\/strong><\/h2>\n\n\n\n
