What are the characteristics of stainless steel ventilation pipes installed in food processing workshops?

Installation characteristics of stainless steel ventilation pipe in food processing workshop

Combined with the core requirements of sanitation, anti-corrosion, mildew prevention, safety compliance and easy cleaning in food workshops, the installation and use of stainless steel air ducts (commonly made of 304/316L material) have the following key features:

I. Material and Hygienic Characteristics

Corrosion resistance and easy bacteriostasis

The food workshop is full of moisture, acid-base cleaning solution, salt, oil fume/water vapor. The 304/316L stainless steel is acid-and alkali-resistant, corrosion-resistant, and it is not easy to breed bacteria, molds and biofilms, so as to prevent the air duct from rusting and chipping to pollute the food.

The surface is smooth and not easy to accumulate dust.

The inner wall is smooth and seamless, and oil, dust and food scraps are not easy to adhere, which reduces the residual dead angle and meets the requirements of clean food production.

Non-toxic and environmental protection

The material is stable, free from volatilization and harmful substances precipitation, and will not cause secondary pollution to raw materials, semi-finished products and finished products, thus meeting the food-grade production standards.

Second, the structure and installation process characteristics

The sealing requirement is extremely high

Full welding, seamless welding or special sanitary flange sealing shall be adopted to prevent air leakage and condensed water leakage, and to prevent cross-odor in workshops and invasion of mosquitoes and microorganisms from gaps.

Non-sanitary dead angle design

Minimize internal bolts, rivets and raised structures; Elbow, tee joint and reducer adopt circular arc transition to avoid material accumulation and pollution and facilitate disinfection and washing.

Anti-condensation and anti-dripping

The temperature difference in the food workshop is large, and the air duct should be installed with insulation and moisture-proof layer to prevent the condensate dripping from the outer wall from polluting the production line and raw material table.

Specification for hoisting layout

Avoid directly above the key areas of food processing; Brackets shall be treated with anticorrosion, and the spacing shall be in compliance, so as to avoid pipeline shaking and dust accumulation, and at the same time, clean maintenance space shall be reserved.

Third, the advantages of use and operation and maintenance

Resistant to high-frequency cleaning and disinfection

It can withstand repeated washing and wiping with hot water, disinfectant and acid-base cleaner, and can withstand high temperature and humidity environment, which is suitable for daily disinfection process in food workshop.

Durable and long life

Compared with galvanized air duct and composite air duct, it has oxidation resistance and aging resistance, is not easy to be damaged and peeled off, reduces the replacement and maintenance cost, and is suitable for long-term continuous production in the workshop.

Convenient for cleaning and maintenance

Sanitary manhole and detachable pipe section can be set up as required, which is convenient for regular internal cleaning, disinfection and colony detection.

IV. Compliance and safety features

Meet the food industry norms

It conforms to SC certification of food production and clean workshop standards, and can be used in workshops with high clean requirements such as cooked food, baking, meat products and aquatic products.

Good fireproof and explosion-proof performance.

Stainless steel is a non-combustible material, which has no risk of flame-retardant coating falling off, and is suitable for open flame processing in food workshops and ventilation and smoke exhaust in high-temperature cooking areas.

Anti-odor crosstalk

Strong airtightness, effective isolation of odor, oil fume and waste gas, and guarantee the air circulation between clean production area and rough machining area.
