Laser cleaning technology ensures that most of the dirt evaporates and the remaining residues fall loose. Not only does the laser cleaning machine clean more thoroughly than traditional methods, but the heat generated by the laser beam also has antibacterial properties, which can effectively remove bacteria and microorganisms from the surface of the substrate. In addition, laser cleaning machines reduce harm to the environment and human health, making them an indispensable innovative technology in the development of the food industry.

Today, we will explore some basic knowledge about laser cleaning machines. In addition, we will also discuss the application of laser cleaning machines in the food industry. We hope that this article will help you choose a laser cleaning machine that suits your needs.

What is laser cleaning technology?

Laser cleaning technology uses high-intensity laser beams to remove oil, rust, oxides and other residues from the surface of metals and other materials.

Thermal decomposition: When the laser beam is irradiated to the surface of the target material, the temperature rises rapidly due to the energy of the beam, accelerating the heating and evaporation of the contaminants. This process is similar to breaking down dirt with high temperatures and is particularly suitable for removing stubborn grease and coatings.

Photolysis: High-energy laser photons interact with contaminant molecules and break molecular bonds. This photolysis effectively removes complex chemical contaminants such as paint and oxide layers.

What are the benefits of laser deep cleaning?

1. Extend equipment life

One of the main advantages of laser cleaning machines is the contactless cleaning process. Contactless means that when dealing with grease and other contaminants, no mechanical tools are required to remove them, and no chemical cleaners or abrasive grinding is required, because the cleaning medium is a high-energy laser beam. The laser beam only acts on surface contaminants without applying friction or pressure to the substrate. Therefore, using a laser cleaning machine will not cause wear and tear on your production equipment.

2. Achieve precise cleaning

The laser beam in the laser cleaning machine can be focused into an extremely small spot with a diameter as small as a few microns. This concentrated energy enables the laser cleaning machine to work in very small areas, such as grooves and narrow spaces that are difficult to clean. In addition, the laser cleaning machine can adjust the pulse width and frequency of the laser according to your cleaning needs. For example, short pulse widths are suitable for removing thin layers of contaminants, while high frequencies can be used for large-scale cleaning. Finally, the laser power can be precisely adjusted according to the complexity of the cleaning task. Lower power is suitable for removing light dirt, while higher power can be used to remove stubborn oxide layers or rust.

3. More hygienic and safer

In the food industry, keeping workbenches and equipment clean is essential for food safety control. Generally, the temperature generated by lasers can reach hundreds or even thousands of degrees Celsius, which is enough to denature bacterial proteins, damage DNA, cause cell death, and effectively clean biofilms. Therefore, the use of laser cleaning machines can not only avoid chemical cleaning agent residues, but also eliminate microorganisms and bacteria, ensure the hygienic safety of food production, and greatly reduce food safety risks.

At the same time, laser cleaning machines effectively prevent workers from contacting corrosive chemical solvents or inhaling fine particles generated during abrasive grinding, ensuring the health and safety of workers.

4. Save time and labor

When cleaning various equipment such as mixers and ovens, laser cleaning machines do not need to use chemical cleaning agents for pretreatment, cleaning, drying, etc., which saves cleaning time, and when the equipment is large or the number is large, it greatly reduces the labor intensity of workers.

5. Environmental protection

Laser cleaning machines avoid the use of chemical cleaning agents, reduce wastewater discharge, protect the environment, and promote worker health. In addition, if the chemical cleaning agent is not rinsed thoroughly, the solvent residue can easily contaminate the food and affect food safety.

Application of laser cleaning machine in food industry

In all links of the food industry, pollutants such as oil, carbide, gel, oxide, rust, etc. will accumulate during daily production. Laser cleaning machine can efficiently and thoroughly clean the equipment and tools used in food processing, ensuring a non-contact cleaning process, without chemical solvents, and no pollution to the food production environment.

1. Degreasing

Laser cleaning machine can effectively remove grease and oil stains on food processing equipment. In the food industry, most departments will produce oil stains during the production process. Regular cleaning and thorough degreasing are related to the taste and safety of food, and will affect the operation of equipment and safety hazards.

What can laser cleaning machine clean?

Frying equipment: used in fried food industry, catering industry, such as fryers, ventilation ducts, walls, floors, etc.

Dairy equipment: mixers, filling equipment and conveyors required for the production of cream and cheese in the dairy industry.

Baking equipment: ovens, baking trays, pans, molds, etc. commonly used in the baking industry.

2. Remove carbides

During the high-temperature cooking and baking process of food, organic matter is easily decomposed into black or dark brown residues. These residues adhere to the surface of the equipment. If they are not completely removed for a long time, they will affect the efficiency and life of the machine and endanger food safety and hygiene. Where do common carbonizations appear?

Baking industry: Residues of flour, sugar, butter, etc. may carbonize, leaving black carbides on the furnace walls, trays and molds.

Fast food industry: Frequent frying and high-temperature cooking will leave carbides on stoves, grills, ovens and exhaust pipes.

3. Makeup remover gel

In the process of food production and processing, if the raw materials contain viscous substances such as sugars, proteins, lipids, thickeners, etc., it is easy for a large amount of viscous substances to accumulate on the surface of production equipment or the inner wall of filling machinery. For example, in the beverage and dairy processing industry, the continuous use of filling equipment will form a thick layer of gel in the pipeline.

Laser cleaning machines can completely remove these gel deposits, ensuring safe food production and the smooth operation of the entire production line.

4. Remove oxides and rust

In the food industry, liquids and metal equipment are used in almost all links during the production and processing, which can easily lead to the formation of oxides and rust, which not only affect the normal operation and service life of the equipment, but also endanger the quality and safety of food.

For example, factories producing alcohol often use large metal fermentation tanks and storage containers. Due to frequent contact with large amounts of liquids and high humidity during the production process, the metal surface is prone to oxidation and rust.

Laser cleaning technology effectively solves these problems, improves the efficiency of the production line, and ensures the quality and safety of the product.

Summary

As an advanced cleaning technology, laser cleaning equipment adheres to the concept of "machines make work easier" to reduce the labor intensity and safety risks of the food industry. If you are looking for a cleaning solution that can meet thorough, precise and efficient requirements while ensuring environmental responsibility and personnel safety during operation, laser cleaning machine is your ideal choice!
