In the fast - paced world of the airline and aviation catering industry, maintaining high - quality and efficient dishwashing processes is of utmost importance. As a leading supplier of Flight Dishwashers, I often get asked about the cleaning cycle of these specialized appliances. In this blog, I'll delve deep into the cleaning cycle of a Flight Dishwasher, explaining each step in detail.
Understanding the Basics of a Flight Dishwasher
Before we jump into the cleaning cycle, it's essential to understand what a Flight Dishwasher is. A Flight Dishwasher, also known as a Flight Dish Machine, is a conveyor - type dishwasher specifically designed for high - volume dishwashing in the aviation catering sector. These machines are built to handle a large number of dishes, glasses, and utensils quickly and effectively, ensuring that they are thoroughly cleaned and sanitized for reuse.


The Cleaning Cycle of a Flight Dishwasher
1. Pre - Rinse Stage
The cleaning cycle of a Flight Dishwasher begins with the pre - rinse stage. In this initial phase, the dirty dishes are loaded onto the conveyor belt of the dishwasher. As they move through the machine, a high - pressure spray of warm water is directed at the dishes. This spray helps to remove large food particles, debris, and loose dirt from the surface of the dishes. The pre - rinse is crucial as it prevents the main wash section from getting clogged with large particles, which could reduce the efficiency of the cleaning process.
The water used in the pre - rinse stage is typically at a temperature of around 30 - 40°C (86 - 104°F). This warm water not only helps to loosen the dirt but also prepares the dishes for the more intensive cleaning that follows. The pre - rinse stage usually lasts for a short period, typically around 15 - 30 seconds, depending on the level of soiling on the dishes.
2. Main Wash Stage
After the pre - rinse, the dishes enter the main wash stage. This is the heart of the cleaning cycle, where the majority of the dirt and grease are removed from the dishes. In the main wash section, the dishes are exposed to a combination of hot water and a specially formulated detergent.
The water in the main wash stage is heated to a higher temperature, usually between 50 - 65°C (122 - 149°F). The high temperature, combined with the detergent, helps to break down and dissolve grease, oil, and stubborn food residues. The detergent used is designed to be highly effective in removing tough stains while being gentle on the dishes and the dishwasher components.
The main wash stage features multiple spray arms that distribute the hot, soapy water evenly over the dishes. These spray arms are strategically positioned to ensure that all surfaces of the dishes are thoroughly cleaned. The duration of the main wash stage can vary, but it typically lasts between 1 - 2 minutes, depending on the type and level of soiling on the dishes.
3. Intermediate Rinse Stage
Once the main wash is complete, the dishes move on to the intermediate rinse stage. In this stage, a fresh supply of clean water is used to rinse off the detergent and any remaining dirt from the dishes. The intermediate rinse helps to prevent the formation of detergent residues on the dishes, which could affect their appearance and taste.
The water in the intermediate rinse stage is at a temperature similar to that of the pre - rinse, around 30 - 40°C (86 - 104°F). This stage usually lasts for about 15 - 30 seconds, providing a quick but effective rinse to remove the soapy water from the dishes.
4. Sanitizing Stage
After the intermediate rinse, the dishes enter the sanitizing stage. Sanitization is a critical step in the cleaning cycle, as it ensures that the dishes are free from harmful bacteria, viruses, and other pathogens. In the sanitizing stage, the dishes are exposed to a high - temperature spray of water or a chemical sanitizer.
If using hot water sanitization, the water temperature is typically raised to at least 82°C (180°F). This high - temperature water kills most of the harmful microorganisms on the dishes. Some Flight Dishwashers also use chemical sanitizers, such as chlorine - based compounds, to achieve the same level of sanitization. The sanitizing stage usually lasts for about 15 - 30 seconds, ensuring that the dishes are properly sanitized for safe use.
5. Final Rinse Stage
The final rinse stage is the last step in the cleaning cycle. In this stage, a final spray of clean, cold water is used to cool down the dishes and remove any remaining sanitizer or debris. The cold water rinse helps to prevent the dishes from drying with streaks or spots, leaving them clean, shiny, and ready for use.
The cold water used in the final rinse is typically at a temperature of around 10 - 20°C (50 - 68°F). This stage usually lasts for about 10 - 15 seconds, providing a quick and refreshing finish to the cleaning process.
Factors Affecting the Cleaning Cycle
Several factors can affect the cleaning cycle of a Flight Dishwasher. These include:
1. Level of Soiling
The more soiled the dishes are, the longer the cleaning cycle may need to be. Dishes with heavy grease or stubborn food residues may require an extended main wash stage or additional pre - rinse cycles to ensure thorough cleaning.
2. Dish Material
Different types of dish materials may require different cleaning parameters. For example, delicate glassware may need a lower - pressure spray and a gentler detergent to avoid damage, while ceramic or stainless - steel dishes can withstand more intensive cleaning.
3. Dishwasher Capacity
The capacity of the Flight Dishwasher also plays a role in the cleaning cycle. A Dishwasher with A Capacity Of 8000 Dishes may have a faster conveyor speed and a more efficient cleaning process compared to a Dishwasher with A Capacity Of 3000 Dishes. This is because larger capacity dishwashers are designed to handle a higher volume of dishes in a shorter period of time.
Importance of a Proper Cleaning Cycle
A proper cleaning cycle is essential for several reasons. Firstly, it ensures that the dishes are thoroughly cleaned and sanitized, which is crucial for maintaining food safety standards in the aviation catering industry. Secondly, it helps to extend the lifespan of the dishes by preventing the buildup of dirt and grease, which can cause corrosion and damage over time. Finally, a well - executed cleaning cycle improves the overall efficiency of the dishwashing process, allowing airlines and catering companies to serve clean dishes to their passengers in a timely manner.
