In the food and beverage industry, refrigeration chambers play an essential role. These cold storage spaces are indispensable for preserving the quality of perishable products and are fundamental to ensuring food safety. Therefore, the cleaning and disinfection of refrigeration chambers are priority processes to maintain high hygiene standards in these critical environments.
The importance of cleaning and disinfecting refrigeration chambers
Maintaining hygiene in a refrigeration chamber can be a challenging task, but its relevance for ensuring food preservation is undeniable. Preventing the accumulation of dirt and the proliferation of microorganisms in these spaces is unavoidable.
In environments with low temperatures and high humidity, characteristic of industrial refrigeration chambers, bacteria, fungi, and other microorganisms find ideal conditions for growth. If we add the presence of dirt and food residues, we create a breeding ground conducive to the proliferation of pathogens, threatening food safety and the quality of stored products.
While regular cleaning becomes an essential procedure to eliminate dirt buildup, the disinfection of chambers goes beyond that. It involves eradicating pathogenic microorganisms that may resist conventional cleaning methods. In effect, the combination of cleaning and disinfection not only ensures a safe storage environment but also safeguards the integrity of stored products, ensuring they reach consumers in optimal conditions.
What helps us prevent effective cleaning and disinfection of refrigeration chambers?
Proper cleaning and disinfection of refrigeration chambers, whether in industrial facilities or refrigerated transport storage, play a crucial role in preventing various risks. Among them, cross-contamination, one of the greatest dangers facing the food industry. This is the most significant factor that could compromise food safety, but cleaning and disinfection are key to preventing it. These processes eliminate residues that could act as contamination agents and eradicate harmful microorganisms, ensuring food safety.
Additionally, cleaning and disinfection contribute to allergen control, preventing fatal consequences resulting from a lack of control. Proper handling, supported by techniques such as color coding, prevents the mixing of allergens with food, thus reducing significant risks.
These processes also have a positive impact on workplace safety, minimizing risks such as slips caused by fallen products or other incidents resulting from a lack of cleanliness. Improving the working environment is a direct consequence of the attention dedicated to the cleaning and disinfection of refrigeration chambers.
Step-by-step cleaning and disinfection of refrigeration chambers
Although refrigeration chambers operate at extremely low temperatures, this does not exempt them from dirt and microorganism accumulation. In this regard, following specific procedures is critical to keeping these facilities clean and ready for use.
Establish a frequency for cleaning the refrigeration chamber
Certainly, the first essential step is to establish a frequency for cleaning and disinfecting the refrigeration chamber. By creating a document detailing who, when, and what tasks should be performed, mandatory maintenance deadlines are established. A visible table next to the door, marking days, responsible parties, and possible incidents detected, facilitates tracking and problem resolution. Maintaining the technical aspects, such as the refrigeration equipment, in optimal conditions is equally vital. Having the phone number of the maintenance service streamlines the resolution of detected problems, ensuring an efficient and long-lasting storage environment.
Remove frost and drain water
Certainly, the presence of frost in refrigeration chambers not only indicates malfunction but also increases energy consumption inappropriately. Consulting the refrigeration equipment manual is essential to determine if there is a predetermined defrosting procedure in the cooling systems used. It is important not to use aggressive methods and allow the ice to melt naturally. In recurring cases, contacting technical service is the best way to address and resolve underlying issues.
Proceed with cleaning
In the cleaning phase of refrigeration chambers, it is essential to follow meticulous steps to ensure a hygienic and safe environment. The choice of products suitable for the stored merchandise is crucial. Another logical precaution is to avoid direct contact of the cleaning agents with the merchandise. Reading the labels of soaps and disinfectants provides essential information about their compatibility with food.
During cleaning, it is also necessary to move the merchandise without breaking the cold chain. The use of appropriate clothing, considering both the duration of use and the products stored in the chamber, is essential to isolate the operator from low temperatures. This precaution not only ensures the effectiveness of cleaning but also the safety of personnel.
Disinfection of refrigeration chambers
Finally, disinfection, a stage following cleaning, becomes a critical step to eliminate microorganisms present on surfaces. This process is carried out by applying chemical substances known as sanitizers. Indeed, cleaning removes visible dirt, while disinfection acts on microorganisms, ensuring a truly sterile environment.
Among the most commonly used sanitizers in the market are compounds based on sodium hypochlorite, chlorine dioxide, or quaternary ammonium salts. The choice of the most suitable sanitizer should be based on the specific properties of each, considering their effectiveness for the desired result. It is important to seek advice from the usual supplier of chemicals and cleaning products, as their recommendations will align with specific needs.
On the other hand, rotating the type of sanitizer throughout the year is critical to avoid unwanted resistance by microorganisms. This strategic approach helps eliminate odor-causing microorganisms and ensures an environment free of pathogens. Attention to the quantity of product, its concentration, preparation, usage temperature, and water quality is fundamental to ensuring the effectiveness of the disinfection process.
Importance of operational maintenance
In parallel with the disinfection of refrigeration chambers, technical maintenance is essential. More than 80% of failures in these systems are attributed to a lack of maintenance. In this context, regular inspections and preventive maintenance tasks are essential to preserve the optimal functioning of the refrigeration chamber and extend its lifespan. Inadequate maintenance can lead to serious consequences, such as excessive condensation pressure, inefficient cooling performance, and very high energy consumption.
Consequently, a refrigeration chamber that does not receive proper maintenance will operate incorrectly and inefficiently, requiring frequent and costly repairs. Preventive maintenance is key to avoiding unfavorable scenarios and ensuring that the chamber operates efficiently and economically.
Refrigeration chamber maintenance tasks
Regular maintenance tasks are fundamental for the proper functioning of refrigeration chambers. These tasks include:
- Inspection of the insulation and seals to verify the tightness of doors and closures.
- Operation of pressure relief valves. This involves regularly inspecting these components to ensure their proper functioning.
- Evaluation of alarms, opening systems, and other safety elements.
- Review of ice formations and condensation, identifying and treating them in advance.
- Removal of accumulated ice around pressure relief valves, floor, and doors.
- Examination and cleaning of the evaporator and condenser to ensure efficient performance.
- Refrigeration panels. Maintaining these elements ensures proper hygiene and condition.
As we mentioned, the described tasks contribute to hygiene and food safety and are essential for the optimal performance of the refrigeration installation.
As a company dedicated to the design and development of industrial and commercial refrigeration systems for 28 years, at Intersam, we understand the importance of combining the cleaning and disinfection of refrigeration chambers with proper technical maintenance. Therefore, we believe it is pertinent to recommend assigning cleaning and sanitization tasks to properly trained operators. In the case of maintenance tasks, it is most convenient to hire specialized companies with qualified technicians.
