Maintenance free plastic fired board dust collector: preferred for hygiene grade dust removal in food factories
Sep 18,2025
For overseas food factories, dust removal equipment not only needs to "remove dust", but also needs to meet the three core requirements of "hygiene without residue, minimal downtime for maintenance, and compliance with food grade standards" - traditional bag filters require frequent bag replacement, are difficult to clean, are prone to residual dust pollution of products, and may also affect production due to maintenance downtime.
1、 Maintenance free design: adapted to the "continuous production without interruption" needs of food factories
Most food factories operate continuously 24 hours a day. Traditional bag filters require 1-2 maintenance shutdowns per month due to clogged and aged filter bags, resulting in losses of over $15000 per shutdown. The maintenance free feature of the plastic fired plate dust collector solves the problem of downtime from the root:
1. Long life filters reduce replacement frequency
The core filter element "plastic fired plate" is made of polymer composite resin material, with a rigid structure that is not easily damaged. The surface is treated with PTFE coating, making it difficult for dust to adhere. The service life is as long as 3-5 years, which is more than 6 times that of traditional food grade filter bags. No need to frequently replace filter materials, only simple quarterly inspections are required, with maintenance time of less than 8 hours per year, far lower than the 100+hours of bag filters, completely avoiding production interruptions caused by bag replacement.
2. Strong self-cleaning ability, no need to disassemble and clean
The surface of the plastic fired board is smooth and hydrophobic. When cleaning, the dust can be completely removed by low-pressure pulse blowing, and there will be no residual "dust dead corners" like cloth bags; At the same time, the rigid structure does not require disassembly and cleaning, avoiding the introduction of impurities that can contaminate the interior of the equipment during the cleaning process - for dust such as milk powder and chocolate powder that are prone to moisture absorption and clumping, it can also maintain the dryness of the filter surface through high-frequency and low-pressure dust cleaning, without the need for manual intervention in cleaning, truly achieving "maintenance free operation".
2、 Hygiene grade characteristics: meet the "no residue, anti pollution" standards of food factories
The core bottom line of dust removal in food factories is "non polluting products". The hygienic design of plastic fired plate dust collectors fully meets the strict requirements of the global food industry
1. Material compliance, no migration risk
The equipment and dust contact parts are made of food grade materials: the shell is made of 304/316L stainless steel, which is acid and alkali resistant and has no metal ion migration; The body of the plastic fired board does not contain harmful substances such as bisphenol A and plasticizers, and complies with the EU 10/2011 and US FDA 21 CFR § 177.2600 standards. Even if it comes into direct contact with dust such as flour and milk powder, it will not produce pollution, avoiding the product from being rejected by overseas markets due to non compliant materials.
2. The structure has no dead corners and is easy to clean and disinfect
The interior of the plastic fired plate dust collector adopts a "circular arc transition+seamless welding" design, with no dead corners of dust residue such as bolts and grooves; The equipment is equipped with a reserved CIP interface, which can be regularly disinfected with food grade disinfectant high-pressure spray to meet the hygiene and disinfection needs of baking and dairy factories. Compared to traditional bag dust collectors, the fiber gaps are prone to accumulate dirt and grime. The rigid and smooth surface of the plastic fired board can completely prevent bacterial growth, and the total bacterial count is controlled below 10CFU/g, which meets the EU food hygiene standards.
3. Sealed to prevent leakage and eliminate cross contamination
Adopting dual silicone rubber gaskets, the overall sealing level of the equipment reaches IP65, which not only prevents external air from carrying impurities into the dust removal system and polluting dust, but also avoids dust leakage to the production workshop, ensuring a clean food processing environment.
For overseas food factories, the "maintenance free+hygiene grade" of plastic fired board dust collectors is not a technical gimmick, but a core capability to solve production pain points and ensure compliance. It not only reduces maintenance costs and downtime losses, but also easily passes global food grade certification, helping foreign trade food factories break through environmental barriers and enhance product competitiveness in the international market. It can be called the "ideal solution" for food factory hygiene grade dust removal.
