Scraping and soaking heavily soiled tableware by hand can take up a surprising amount of time in a busy restaurant kitchen. When plates, bowls or other washable items arrive with grease and dried food residue, sending them straight to the next washing stage may not be the most efficient workflow.
The Hengze HZ-GP1500 Commercial Bubble Washer is designed to add an active pre-cleaning stage before the main washing process. Instead of leaving items in still water, the machine uses vortex-style bubble agitation to keep water moving around the load, helping loosen food residue and grease during soaking.
Its 250 L tank provides the capacity required for busy foodservice operations. Water temperature can be adjusted between 40°C and 55°C, while a 6 kW heating system keeps the washing water heated during operation. A 0.55 kW blower generates the airflow needed for the vortex bubble action.
The HZ-GP1500 Bubble Washer also helps deal with the residue removed during pre-cleaning. An overflow oil-separation and debris filter collects floating grease and larger food particles, reducing the amount of solid residue flowing toward the drain.
Practical details are built around everyday kitchen use. Water-level detection helps protect the heating system against dry operation, a rotatable stainless steel faucet makes water handling more convenient, and the stainless steel body provides a durable structure for commercial working environments.
For restaurants planning their washing area, this machine can be used alongside dishwashers, sinks, worktables and other Restaurant Kitchen Equipment to create a more organized flow from dirty tableware to final washing.

The HZ-GP1500 keeps water moving through vortex-style bubble agitation rather than simply leaving heavily soiled items in a stationary soaking tank.
This movement helps loosen grease and attached food residue before the next washing stage.
A 250 L tank gives restaurants and canteens more room for batch pre-cleaning during busy service periods.
Temperature can be adjusted between 40°C and 55°C according to the actual cleaning requirement.
Heated soaking works together with bubble agitation to help tackle greasy and stubborn soils.
The machine is equipped with a 6 kW stainless steel heating tube for heating the washing water.
A 0.55 kW blower generates airflow for the vortex washing action, creating continuous movement inside the tank.
Floating oil can be separated through the overflow design instead of remaining entirely mixed with food debris in the washing area.
The integrated filter catches larger food particles removed during washing, helping reduce solid residue entering the drainage system.
The machine monitors water level and automatically cuts power when insufficient water is detected, helping prevent dry heating.
The stainless steel body and supporting feet provide a strong structure for repeated use in commercial washing areas.
The stainless steel faucet can be rotated as needed, making water filling and cleaning around the tank more convenient.
The control panel is designed around the main operating functions, making temperature setting and everyday use straightforward for kitchen staff.

The HZ-GP1500 is suitable for foodservice operations where heavily soiled items need soaking or auxiliary cleaning before entering the main washing process.
Typical users include restaurants, hotel kitchens, banquet operations, school dining halls, factory canteens, employee cafeterias, catering kitchens and central kitchens.
For restaurants handling oily dishes or large quantities of used tableware during peak periods, the commercial bubble washer can provide a dedicated pre-cleaning area instead of relying entirely on manual sink soaking.
It can also form part of a larger restaurant kitchen equipment layout, working alongside dirty-dish tables, sinks, commercial dishwashers and tableware conveying equipment.
Hengze can help customers determine how the HZ-GP1500 should fit into their existing dishwashing workflow.
Before quotation, customers can provide information about the items being washed, expected washing volume, kitchen layout, available space, electrical supply and existing dishwashing equipment.
For new restaurant projects, Hengze can also discuss the bubble washer together with other restaurant kitchen equipment to help coordinate the pre-washing and dishwashing area.
Support includes installation guidance, operating instructions, remote troubleshooting, maintenance guidance and long-term spare-parts supply.
OEM requirements can also be discussed for distributors and commercial kitchen project customers.
The HZ-GP1500 is prepared for export with suitable protection around the machine body, control area and key components to reduce the risk of damage during transportation.
The machine dimensions are:
1500 × 800 × 850 mm
Before shipment, customers should confirm that the installation site can support the standard electrical specification of 380V / 3N / 50Hz and the rated power of 6.55 kW.
Final packing dimensions and weight are confirmed according to the actual export packing and order configuration.
For complete restaurant kitchen projects, the bubble washer can also be arranged for shipment together with commercial dishwashers and other kitchen equipment.
The HZ-GP1500 is designed for auxiliary washing and pre-cleaning. It uses heated water and vortex bubble agitation to help loosen grease and food residue before the next washing stage.
Restaurants handling large amounts of greasy or heavily soiled tableware may need a dedicated pre-cleaning stage. A commercial bubble washer provides active soaking and agitation rather than relying only on manual soaking in a sink.
The machine is specified for auxiliary cleaning, so it should not automatically be considered a replacement for a commercial dishwasher. It is better positioned as part of the pre-washing process.
A conventional sink mainly provides stationary soaking. The HZ-GP1500 adds air-driven vortex agitation and adjustable heated water, creating more movement around the items during pre-cleaning.
The bubble and heated soaking action can help loosen grease and attached food residue, which may reduce the amount of manual pre-scrubbing required. Actual results depend on the type and condition of the soil.
The washing tank has a capacity of 250 L.
