shelves, mixers, dough dividers, moulders, conveyor belts, packaging machines and internal oven surfaces. Industrial vacuum cleaning allows residues to be removed without redistributing them throughout the environment using brooms or compressed air, helping make cleaning operations faster and more controlled. Cleaning inside ovens, however, requires a specific configuration defined according to the actual material temperature, filter type, thermal resistance of the hose and accessories and the absence of embers or incandescent residues.
FEVI solutions suitable for ovens, bakeries and food-processing facilities
The compatibility shown below is application-based. The final configuration must be confirmed case by case according to the type of residue, temperature, quantity generated, operating frequency, hygiene requirements and any ATEX classification of the environment.
Criteria for selecting the extraction system
The correct industrial vacuum-cleaner configuration must be defined by analysing three fundamental areas of the cleaning process:
1. Nature and Temperature of the Residue
Assessment of the material to be collected: flour, sugar, fine dust, crumbs, crusts, dried dough, damp residues or material that is still warm from inside the oven.
2. Cleaning and Filtration Requirements
Verification of cleaning frequency, quantity generated, area to be cleaned, hose length, filtration class and any requirement for automatic filter cleaning.
3. Safety, Hygiene and ATEX Risk
Assessment of food-dust combustibility, area classification, HACCP procedures, allergen management and the thermal compatibility of the entire configuration.
Ovens and bakeries generate different types of residue
Flour, sugar and fine food dust: Weighing, dosing, transfer, mixing, dusting and packaging operations can generate lightweight dust prone to caking. Flour, semolina, starch, icing sugar, cocoa and food preparations tend to settle on surfaces and can rapidly clog conventional filters. For frequent cleaning, an adequate filter surface area and cleaning systems capable of maintaining more stable extraction performance should be used.
Crumbs, breadcrumbs and solid residues: Cutting, handling, baking and packaging generate crumbs, bread fragments, seeds, cereals, crusts, dried-dough residues and small solid waste. These materials can be collected from floors, tables, machinery, conveyor belts and areas beneath production lines using industrial vacuum cleaners with vacuum pressure and collection capacity proportionate to the volume generated.
Adhering residues or residues inside ovens: Baked flour, crusts, sugar, grease, crumbs and carbonised residues may adhere to the oven floor, walls, trays or baking chambers. When the material is not loose, vacuum cleaning must be combined with mechanical action using lances, brushes or compatible accessories. The actual residue temperature at the time of cleaning must be verified before starting the industrial vacuum cleaner.
IMPORTANT NOTICE: The presence of a filter with Nomex properties and high-temperature resistance does not permit the collection of flames, embers, incandescent residues or burning materials. The filter temperature rating does not automatically correspond to the maximum temperature permitted for the complete machine. The hose, connections, seals, accessories, container, extracted-air temperature and duration of the operation must also be verified. The oven must be switched off and the material must be in a condition compatible with the configuration being used.
Applications in bakeries and food-production departments
Floors, work surfaces and shelving
The industrial vacuum cleaner allows flour, crumbs, seeds, dust and small residues deposited on floors, tables, shelves, racking and production structures to be collected. Vacuum cleaning avoids resuspending the material using brooms or compressed air and allows operators to reach corners, gaps and difficult-to-access areas.
Mixers, hoppers and production lines
Flour, semolina and dry ingredients can accumulate around loading openings, beneath mixers, in dosing areas and along conveying systems. Localised vacuum cleaning can be used to clean the external surfaces of machinery, machine bases and underlying areas, in accordance with the shutdown and safety procedures specified by the equipment manufacturer.
Dough dividers, moulders and packaging machines
These machines generate crumbs, flour, product fragments and residues that can settle on guards, beneath conveyor belts or around processing components. The selection of lances, nozzles and hoses must take the machine geometry, residue size and the need to reach narrow spaces without damaging components or surfaces into account.
Cleaning inside professional ovens
Cleaning baking chambers requires an industrial vacuum cleaner configured for compatible warm dry residues, equipped with a temperature-resistant filter and suitable accessories. Before cleaning, the oven shutdown, cooling time, material temperature, absence of embers and compatibility of the entire vacuum line must be verified.
Technology classification: Industrial Vacuum Cleaner, Dust Collector or Centralised System
To identify the most appropriate system, FEVI distinguishes three principal technologies:
- Industrial Vacuum Cleaner (High Vacuum): The appropriate solution for collecting flour, crumbs, dust and residues already deposited on floors, machinery and surfaces. It uses relatively small-diameter hoses and is also the technology normally used for localised cleaning inside ovens through a dedicated thermal configuration.
- Dust Collector (High Airflow / Low Vacuum): Suitable when dust becomes airborne during dosing, transfer, mixing, sieving or ingredient loading. It is connected to hoods, enclosures, hoppers or capture points and moves a greater volume of air than a conventional industrial vacuum cleaner.
- Centralised System: The solution to consider when several departments, floors or workstations must be served. It includes a central vacuum unit, piping network, distributed extraction points and a collection system sized according to simultaneous use, line length and the characteristics of the food dust.
Key parameters to verify before configuration
Before recommending the final model, we assess the following factors together: type of business, including bakery, pastry shop, oven, biscuit factory or food-processing facility; nature of the residue, including flour, sugar, crumbs, crusts, dried dough, fine dust or damp material; oven temperature and actual residue temperature at the time of cleaning; time elapsed since shutdown; presence of embers, incandescent points or burning material; daily quantity generated; frequency and duration of cleaning operations; area to be cleaned; piping length and diameter; thermal compatibility of the filter, hose, connections, seals and accessories; requirement for HEPA filtration, automatic ICLEAN cleaning or Longopac collection; HACCP requirements and allergen management; dust-combustibility values; ATEX classification of the department; and container-emptying method.

Oven and Bakery Solutions FAQ
Which industrial vacuum cleaner is required to clean inside a professional oven?
Read more
A model specifically configured for compatible warm dry residues must be used for this application. FEVI WM 220 BASIC OVEN is equipped with a filter with Nomex properties and is designed for internal oven cleaning after shutdown and verification of the material temperature and condition.
Why is a Nomex filter important when cleaning ovens?
Read more
Nomex provides greater thermal resistance than a conventional polyester filter and allows the industrial vacuum cleaner to be configured for collecting compatible warm residues. The filter resistance must nevertheless be assessed together with that of the hose, accessories, seals and other machine components.
Does a Nomex filter rated at 200 °C permit the collection of any material at 200 °C?
Read more
No. The 200 °C value refers to the properties of the filter material and does not automatically represent the maximum temperature permitted for the complete machine. The actual residue temperature, duration of the operation and thermal compatibility of all components exposed to the extracted airflow must be verified.
Can embers or incandescent residues inside the oven be collected?
Read more
No. Flames, embers, incandescent points, burning materials or residues capable of causing ignition must not be collected. The oven must be switched off and the material must be in a condition compatible with the industrial vacuum cleaner and accessories used.
Can the same industrial vacuum cleaner be used for the oven and the floors?
Read more
Only when the configuration, accessories and hygiene procedures permit it. In food-production departments, dedicating the machine, hose and tools to a specific area or process may be preferable to reduce the risk of cross-contamination and allergen transfer.
Which industrial vacuum cleaner is suitable for collecting flour and fine food dust?
Read more
In non-classified areas, industrial vacuum cleaners with HEPA + PTFE filtration and automatic ICLEAN cleaning can be considered, including FEVI 220 ICLEAN, FEVI 350 ICLEAN and FEVI TDC30 ICLEAN. The selection depends on quantity, operating frequency, particle size and piping length.
Are all bakeries required to use an ATEX industrial vacuum cleaner?
Read more
No. The presence of flour or sugar alone does not automatically determine the model to be used. The need for an ATEX configuration depends on the risk assessment, dust characteristics, foreseeable concentration, ignition sources and official classification of the area.
Can flour and sugar create an explosion risk?
Read more
Yes. When finely divided and dispersed in air at sufficient concentrations, they can form potentially explosive atmospheres. The assessment must consider the actual product, particle size, moisture content, quantities, process and department classification.
What is the difference between an industrial vacuum cleaner and a dust collector in a bakery?
Read more
An industrial vacuum cleaner operates at high vacuum pressure and is suitable for collecting residues already deposited on floors, surfaces and machinery. A dust collector instead operates at high airflow and is used to capture suspended dust directly from hoppers, mixers, dosing systems, sieves or hoods.
Is a HEPA filter always necessary for food dust?
Read more
No. The need for a HEPA filter depends on particle size, hygiene requirements, material hazards and internal procedures. In high-temperature applications, the thermal compatibility of any secondary filter must also be assessed separately.
Does vacuum cleaning replace washing and sanitising surfaces?
Read more
No. Vacuum cleaning removes dust, crumbs and solid residues but does not automatically perform a cleaning, disinfecting or sanitising function. After mechanical removal, the procedures specified by the cleaning plan and the company HACCP system must be applied.
How can the risk of cross-contamination during vacuum cleaning be reduced?
Read more
Dedicated or clearly identified accessories should be used, equipment used for different allergens should be separated, container-emptying and cleaning procedures should be defined, and filters, hoses and the filter chamber should be inspected periodically. In more sensitive applications, dedicating one industrial vacuum cleaner to a single production area may be appropriate.
Can liquids, grease or damp residues inside the oven be collected?
Read more
Only with an industrial vacuum cleaner specifically configured for compatible liquids and after verifying the temperature, viscosity and composition of the material. FEVI WM 220 BASIC OVEN should be considered mainly for collecting dust, crumbs and compatible warm dry residues.
Can a centralised extraction system be installed in a large bakery?
Read more
Yes. Large facilities can be equipped with a system comprising a central vacuum unit, piping network and distributed extraction points throughout the departments. Airflow, vacuum pressure, pipe diameters, simultaneous use, filtration and ATEX classification must be sized according to the layout and residue characteristics.
