A pass through dishwasher is a staple in many commercial kitchens, from bustling restaurants to large catering services. As a trusted supplier of these efficient machines, I'm excited to delve into how they work and why they're such a game - changer in the world of dishwashing.
The Basics of a Pass Through Dishwasher
At its core, a pass through dishwasher is designed to streamline the dishwashing process in high - volume settings. It gets its name from the way dishes "pass through" the machine from one end to the other. This continuous - flow operation allows for a much higher throughput compared to traditional dishwashers.
Loading Station
The process begins at the loading station. Here, soiled dishes, glasses, and utensils are placed onto racks. These racks are carefully designed to hold items securely in place during the washing process. They are usually made of sturdy materials like stainless steel to withstand the high - pressure water and harsh detergents used in the dishwasher.
The loading area is often equipped with a pre - rinse system. This preliminary step helps to remove large food particles and debris from the dishes. The pre - rinse can be either manual or automated, depending on the model of the dishwasher. Manual pre - rinses require an operator to use a handheld sprayer to rinse the items, while automated pre - rinses use a series of nozzles to spray water over the dishes as they are loaded onto the rack.
Washing Zone
Once the racks are loaded, they are moved into the washing zone. This is where the real cleaning action takes place. Inside the washing zone, there are multiple levels of spray arms. These spray arms are connected to a powerful water pump that circulates hot water and detergent throughout the chamber.
The water used in the washing process is typically heated to a high temperature, usually between 140°F and 160°F (60°C - 71°C). The high temperature helps to break down grease, oil, and food residues on the dishes. The detergent, which is added to the water, further enhances the cleaning power by lowering the surface tension of the water and helping to lift dirt and grime from the surfaces of the items.
The spray arms rotate at high speeds, ensuring that every part of the dishes in the rack is thoroughly cleaned. Some advanced models of pass through dishwashers use a combination of high - pressure and low - pressure sprays. The high - pressure sprays are used to target stubborn stains, while the low - pressure sprays are used to gently clean more delicate items like glassware.
Rinse Zone
After the washing cycle is complete, the racks move into the rinse zone. The purpose of the rinse zone is to remove any remaining detergent and loosened debris from the dishes. In this zone, fresh, clean water is sprayed over the items.
There are two main types of rinse systems used in pass through dishwashers: chemical rinse and hot water rinse. Chemical rinse systems use a small amount of rinse aid, which is a chemical agent that helps to reduce water spotting and improve drying. The rinse aid is added to the rinse water, and as the water sprays over the dishes, it leaves a thin film that helps the water to sheet off the items.
Hot water rinse systems, on the other hand, rely on high - temperature water (usually around 180°F - 195°F or 82°C - 91°C) to sanitize the dishes. The high - temperature water kills bacteria and other microorganisms on the surface of the items, ensuring that they are safe for reuse.
Drying Zone
Once the rinsing is done, the racks enter the drying zone. In this zone, hot air is circulated around the dishes to remove any remaining moisture. The drying process can be achieved through different methods.
Some dishwashers use a forced - air drying system, where a fan blows hot air over the dishes. The hot air evaporates the water on the surface of the items, leaving them dry and ready for use. Other models use a combination of residual heat from the rinse water and natural air circulation to dry the dishes.
Unloading Station
Finally, the clean and dry dishes reach the unloading station. Here, an operator removes the racks from the dishwasher and empties the clean items onto a storage area or directly back into service.
Advantages of Pass Through Dishwashers
One of the main advantages of pass through dishwashers is their high capacity. They can handle a large number of dishes in a relatively short period of time, making them ideal for busy commercial kitchens. For example, a well - designed Commercial Pass Through Dishwasher can wash and dry hundreds of dishes per hour.
Another advantage is their efficiency. The continuous - flow design reduces the amount of time and energy wasted on loading and unloading individual items. Additionally, the high - temperature water and powerful cleaning agents used in these dishwashers ensure a thorough and hygienic clean.
