Jackson Flight Type Dishwashers
While a conveyor dishwasher that can wash nearly 300 racks per hour meets the needs of even the largest restaurants, institutional kitchens in hospitals, schools, and correctional facilities often need more throughput. A flight-type dishwasher is made for high-volume kitchens and, with the exception of flatware, does not require the use of warewashing racks.
These dish machines use conveyor belts to move dishes through compartments, each of which completes one part of the wash cycle. Because of that segmentation, these take up a lot of floor space at a minimum of 181⁄2 feet long. But, their ability to wash tens of thousands of pieces per hour and highly customizable nature enable them to meet a wide range of needs for those industrial-volume operations.
JFT Standard Features
The JFT line of flight-type warewashers is constructed from 16-gauge 304 stainless steel, which is durable and corrosion resistant. The 29-inch-wide peg belt carries dishes through the warewasher without the need for a rack, though more delicate items and flatware should be sent through in a covered open rack. The belt can move at two speeds and has an overload safety interlock and automatic shutdown to prevent damage to the unit if something jams the belt. Each section, also called a tank, has its own door for easy access for maintenance, and each door has a safety switch that will shut down the wash cycle if it’s opened while the machine is running to prevent injuries. These doors, like the panels and hoods, are insulated to reduce the amount of heat and noise that escapes into the surrounding area.
The water tanks in the JFT are filled automatically, with incoming water entering through the final rinse section, which ensures the final rinse is done with the cleanest water in the system. As water drains from each tank, it is used in the next one down the line, until it is used for the last time in the pre-wash tank and drained at the loading end of the machine. Each section's tank is sloped for easy and complete draining, with pumps that are easily accessible for service. Scrap screens are used in each section to capture debris and should be emptied regularly to help keep water as clean as possible as it progresses through the tanks. To help ensure proper water temperatures are reached for cleaning and sanitizing, the control panel features a series of digital readouts that display those levels for each section when it is in use.
The JFT Flight Machine includes a built-in vent, which uses a 0.19 horsepower exhaust fan and requires an indirect vent connection for removing condensate and complying with building codes. The cross duct that houses the fan is easily accessible for cleaning. The Jackson JFT will always be assembled and installed by Jackson factory-authorized personnel, and will be set up with a minimum of 3 inches of clearance from the nearest wall. An electrician and a plumber will be required to make the relevant utility connections; then, the factory-authorized installers will also run a performance test and conduct operator training after the unit is installed.
JFT Flight Machine Sections
The standard Jackson JFT flight machine has two speeds, 6.8 feet per minute and 8.6 feet per minute, allowing users to wash from 11,832 to 14,964 dishes per hour. These units are highly customizable, with options that can affect the length of the machine by adding sections for additional washes and rinses or features like blower dryers. Because of their customizable nature, these can be made to operate in the direction that best fits your workflow.
Below are the sections available in the JFT flight machine:
1. Loading Section
The loading area of the JFT flight type dishwasher has a section of the conveyor belt, which is made to hold dishes without needing racks, exposed to make loading dishes simple. The platform is made of 12-gauge stainless steel for a durable loading surface and includes a start/stop button for convenience. An additional load section can be added to give operators more time to add dishes to the conveyor belt.
2. Pre-wash Tank
The pre-wash tank has water jets that are optimized with a 3-horsepower motor for removing food from dishes. A removable stainless steel strainer allows for easy discarding of large debris removed from dishes and prevents clogs of the drain water system.
3. Wash Tank
This section uses a 3-horsepower motor to remove any remaining soil and clean dishes thoroughly. A strainer is also used to prevent clogs in this tank, and the wash tank operates on a slope to aid in draining and prevent soil buildup. If the system will be used to clean heavily-soiled items like pots and pans with baked-on residue, an additional wash tank can be added to ensure wares are thoroughly cleaned.
4. Power Rinse Tank
Clog-free water jets in this section are powered by a 2-horsepower pump motor to ensure complete rinsing of wash detergent. The rinse arms can easily be removed for cleaning. The onboard booster heater is rated to heat 155 gallons per hour of 110 degree F water to the 180 degrees F necessary to ensure full sanitization of wares.
5. Final Rinse Tank
This is where the water actually comes into the washer, meaning the last rinse water that touches the dishes is entirely free of detergent. This section also houses the control cabinet, where the control panel and power connection are located.
6. Blower Dryer
This is an optional section that uses a 0.6-horsepower motor to power an industrial squirrel-cage-style fan that dries dishes as they exit the warewasher. This section also prevents personnel from removing dishes before they get to the end of the unloading section.
7. Unload Section
This is where dishes are removed from the machine after being rinsed or dried, depending on your machine's configuration. This is also where the drive shaft that powers the conveyor belt is located, as well as another start/stop button for safety and convenience. This area can be extended by specifying an additional unload section, giving operators more time to unload dishes before they reach the end of the conveyor.
The Jackson LoH2O flight-type warewasher is part of the JFT line, but it is made to optimize water usage to support conservation efforts. The LoH2O uses less than half the water of the standard JFT, at only 58 gallons per hour. To make the best use of its water, the LoH2O model uses Jackson’s unique Rainbow Rinse™ design. This design features an arched upper rinse arm that ensures superior rinsing while reducing water usage. Because of the lower water consumption, however, this model’s belt operates at slower speeds from the standard JFT, which results in lowered dish capacities.
|Feet Per Minute||Dishes Per Hour|
|JFT High Speed||8.6||14,964|
|LoH2O High Speed||6.7||11,094|
|JFT Low Speed||6.8||11,832|
|LoH2O Low Speed||5.3||8,772|
