Frequently Asked Questions - KPS-80DS Blodgett

What is the recommended steam pressure range for the KPS-80DS?

The recommended steam pressure is between 5 and 30 PSI (0.3-2.1 kg/cm²). If incoming pressure exceeds this, a pressure reducing valve must be installed.

How do I clean the kettle properly?

Clean the kettle immediately after each use. First, ensure the steam supply is OFF. Pre-rinse inside with warm water, then use a mild detergent and a nylon brush. Rinse thoroughly with clean water. Avoid steel wool, scouring powder, and any cleaners containing chlorides, acids, or salts as they can cause pitting and corrosion.

Why is the water not boiling quickly?

If the water or food does not boil at 2-3 gallons per minute, check that the incoming steam pressure and piping are adequate. Ensure the steam control valve is fully open (counterclockwise) and that a pressure gauge is installed to monitor supply pressure.

What are the installation requirements?

The kettle must be placed on a level floor with proper drainage. For the KPS-80DS (pedestal model), mark and drill holes for the pedestal base, insert expansion shields, and bolt down with 5/16" lag bolts. Seal around the pedestal with sealant to meet NSF requirements. Connect the 3/4" steam supply line with a strainer and the 1/2" condensate return line with a steam trap.

Can I use acidic or chlorine-based cleaners?

No. Do not use cleaning agents that are corrosive, such as those containing chlorides, acids, or salts. Over time, these will cause pitting and corrosion, which is not covered by warranty. Only use mild detergents and warm water.

How do I clean the draw-off valve?

Make sure the kettle is empty and the steam supply is OFF. Turn the large hex nut counterclockwise by hand until disengaged. Slowly pull out the valve stem and disc (avoid dropping the disc). Wash the stem, disc, and handle with mild detergent. Use a nylon brush to clean inside the valve body and tangent tube. Reassemble and tighten the hex nut fully by hand. Leave the valve open when not in use.

What is the purpose of the safety relief valve?

The safety relief valve is set to relieve excess pressure inside the kettle jacket. It must never be plugged or blocked, as it prevents dangerous pressure buildup.

What are the dimensions of the KPS-80DS?

The approximate overall dimensions are: Height 42.5" (1080mm), Width 33" (838mm), and Depth 28" (711mm). Refer to the manual's dimension table for exact measurements, including connection locations.

How do I level the kettle?

For pedestal models like the KPS-80DS, the base is bolted directly to the floor. Ensure the floor is level before installation. For tri-leg models, adjust the flanged feet to level the kettle.

What should I do if the steam line has water accumulation?

If large amounts of water accumulate in the steam line, install one or more ball float traps in the line to remove the water. This ensures efficient steam supply to the kettle.

DESCRIPTION

All direct connected steam jacketed kettles pertaining to this manual are direct steam operated pressure vessels of a double-wall stainless steel construction forming a steam chamber (jacket) enveloping the lower two thirds of the kettle bowl surface. Kettles included are tilting and stationary, floor mounted in fixed positions either on legs with adjustable flanged feet or pedestals. All kettles are equipped with a drain cock, safety relief valve and a steam control valve.

FUNCTIONING MODE

Blodgett direct connected steam jacketed kettles consist of a stainless steel bowl and a stainless steel jacket which envelopes two thirds of the lower surface of the bowl thus forming a sealed pressure vessel (chamber) into which steam is introduced by means of a manual control valve.

The kettle bowl is the container for the food product which ideally should be of a liquid or semi-liquid consistency to achieve complete contact with the bowl surface and thus fully absorb the heat transmitted through the surface.

The temperature required for the cooking process to function adequately must be greater than the boiling point of the liquid food product. Further, the greater the steam pressure used, the higher the temperature and consequently the quicker the cooking process. For example, steam pressurized at 30 PSI attains a temperature of 274^ F ( 135^ C).

1. Select a location to provide drainage for kettle pour path when tilted and for draw-off valve if so equipped.
2. Mark hole locations through flanged adjustable feet on tri-leg models and through pedestal base on pedestal models. Remove kettle.
3. On hole locations marked, drill holes and insert expansion shields to accommodate 5/16" size lag bolts.
4. Reposition kettle. On tri-leg models level kettle by making necessary adjustment on flanged foot.
5. Bolt down kettle and seal with Silastic or other equivalent sealing compound. Sealant must be applied not only to bolt heads but also around flanges or pedestal base making contact with floor surface to fulfil NSF requirements.

6. Connect steam line (3/4" pipe size) to the kettle, making sure there is a steam control valve strainer fairly convenient to the kettle.

7. Connect kettle condensate return line to a drain or to a boiler return line. Each kettle return line must have a suitable steam trap. Boiler return lines must have a check valve.

8. Safety relief valve on kettle must not be plugged as it is set to relieve excess pressure in the kettle.
9. If incoming steam pressure is greater than kettle maximum operation pressure then a pressure reducing valve must be installed in the line.
10. If large amounts of water accumulate in the steam line it will be necessary to install one or more ball float traps in the line to eliminate the water.
11. A steam line pressure gauge is also recommended to determine the actual amount of steam being supplied to the kettle.
12. Check for proper operation.

TILTING KETTLES

1. If kettle has draw-off valve, close it.
2. Fill kettle with product to desired level.
3. Slowly turn the steam control valve ON to full open position (counterclockwise).
4. The water or food should boil 2 to 3 gallons per minute. If it does not then incoming pressure and piping should be checked to determine that it is adequate to operate the kettle efficiently.
5. Regulate steam control valve depending on type of food being prepared.
6. When food is cooked, turn off steam, remove food and clean kettle immediately to prevent residue from drying on kettle bowl surface.

STATIONARY KETTLES

1. Ensure that draw-off valve is closed.
2. Fill kettle with product to desired level.
