137FoodProcessing.jpg Food Processing

Food processing industries move a variety of products – grain, sugar, flour, dairy, cocoa, cereal, spices and many more. Depending on the application, there may be concern with cross contamination, sanitary regulations, and/or food handling regulations.

Donaldson® has a wide variety of dust collectors that can be applied in the food processing industry ranging from small bin vents to large baghouses customised to meet the specific needs for each type of food product.

Dust collectors or “material separators” in the food industry keep the product in the process stream through use of a bin vent collector such as the PowerCore® CP unit, preventing the loss of valuable ingredients and removing a potential waste stream. PowerCore filters represent the latest technology in dust collection and outperform baghouse collectors in a smaller space.

Processes Involving Food Dust

Food processing applications produce dusts on both the upstream and downstream sides of the process. Upstream nuisance, pre-process, and out of plant sources can require dust collection. While downstream the production processes, and other internal process plant sources drive the need for dust collectors. The types of processes found in the food industry may include:

​Mixing

​Conveying

​Screening

​Packaging

​Drying

​Blending

​Extruding

​Weighing

Special considerations for Food dust

Many food dusts are combustible and those operations generating or handling food dusts can require special mitigation efforts to minimise fire and explosion risks. Standards such as TBC can provide guidance for those who generate and handle these types of dusts.

See the Donaldson Dust Collectors and Combustible Dust Strategies brochure

Although generally free flowing when dry, many dried food powders and additives are highly moisture sensitive or hygroscopic. Oils and fats also produce sticky, cohesive dust cakes with nodules adhering to the media surface. These dusts can have a tendency to pack and bridge between filter bags and inside element pleats, so special consideration when designing a dust collector is required to ensure the best type of filter media.

Designing ducting for easy and regular inspection, maintenance and cleaning with inspection doors and easy to dismantle joints.

Depending on the industry and type of food process, there may be additional specifications/guidelines covering the design of the dust collector. Types of standards that could be in place include:

  • 3A sanitary standards
  • Baking Industry Sanitation Standards
  • FDA/USDA
  • NSF/3A 14159 or ISO 14159
  • Company specific sanitary design standards

 

Equipment Options

  • Stainless steel contact surfaces
  • Wash down/clean out designs
  • FDA approved paint
