Food cleaning: how to remove Hotmelt glue?

Among the many services in dry ice cleaning, dry ice blasting in food industry offers a wide variety of applications. Learn in this video how to remove glue on surfaces with complex geometry.

Why use dry ice cleaning in the agri-food sector?

  • Sector : Food glue manufacturing
  • Treatment object : hotmelt glue manufacturing process
  • Equipment used : ATX25-E

Keeping food surfaces clean is the main concern of the production manager. The elimination of food residues, fats, and other residues related to the use of production equipment are essential to prevent the development of bacteria and to ensure safe and high-quality food products.

As sanitation regulations become stricter, labor costs rise, and the industry becomes more environmentally conscious, food businesses are looking for new cleaning processes and solutions.

Unfortunately, traditional cleaning processes, such as steam, water, and manual washing with detergents, are slow, time-consuming, and sometimes inefficient.

How to remove glue on production processes in this case? The answer is: by the cryogenic cleaning process.

The dry ice spray cleanliness solution is similar in its operation to sandblasting, but the comparison stops there.

Safe for food processing environments, cheaper, cryogenic cleaning more efficiently and ecologically!

How does dry ice cleaning work?

How to remove glue in food processing

Dry ice blaster units, or Cryoblaster, are fully mobile and autonomous systems. Dry ice pellets or mini-cylinders with a diameter of 3 mm, comparable to the size of a grain of rice, are routed from the blaster tank to a stream of compressed air.

The pellets move along a flexible pipe and are projected by a nozzle at very high speed at a speed close to that of sound.

The operator directs the flow of dry ice under pressure on the surface to be cleaned.

The treatment is gentle because the hardness of dry ice is comparable to that of chalk.

3 phenomena in action:

  • The first action of this process is the creation of cracks on dirt: dry ice charged with kinetic energy weakens pollution. In some cases, such as abduction sticker or adhesive, the gluing process is instantaneous.

  • The second action is the thermal differential generated by the low temperature of the carboglace -80 °C, which facilitates the detachment of the pollution and in the case of the glue, it is hardening.
  • The third action is the sublimation of dry ice or in other words the transition from the solid-state to the gas state of dry ice.

The answer to the question“how to remove glue?” is simple with cryogenics:

  • you can remove adhesives without damaging surfaces on glass, plastic, stainless steel, PVC
  • no solvent or diluent only dry ice
  • walls, machine tools, tiles can be cleaned to remove food glue, neoprene glue, cyanoacrylate, tape, etc.

Examples of applications to remove glue in food processing

Thanks to Cryoblaster, material® you can clean

  • labellers and packers,
  • production and processing equipment,
  • Glue nozzles,
  • ancillary equipment: forklift, pallet truck, electric motors, control panels
