Frequently Asked Questions - KLS-30DS Blodgett

What steam pressure is required for the KLS-30DS?

The standard operating pressure is 5-30 PSI (0.3-2.1 kg/cm²). An optional range of 5-45 PSI (0.3-3.1 kg/cm²) is available, but a pressure reducing valve is required if incoming pressure exceeds the kettle's rating.

How often should I clean the kettle?

Clean the kettle immediately after each use. Use a mild detergent and warm water with a nylon brush. Avoid steel wool or scouring powders as they scratch stainless steel. Rinse thoroughly and leave the draw-off valve open when not in use.

What safety features does the kettle have?

The kettle is equipped with a safety relief valve to relieve excess steam pressure. Do not plug or modify this valve. Also, the installation instructions warn against storing flammable vapors or liquids near the appliance.

Can I use corrosive cleaning agents?

No. Cleaning agents containing chloride, acids, or salts are corrosive and may cause pitting and corrosion, which is not covered by warranty. Use only mild detergents.

What should I do if the water does not boil?

If the water or food does not boil at a rate of 2-3 gallons per minute, check the incoming steam pressure and piping. Ensure the steam control valve is fully open (counterclockwise). The supply must be adequate for efficient operation.

How do I clean the draw-off valve?

Ensure the kettle is empty. Unscrew the large hex nut counterclockwise, slowly pull out the valve stem and disc, being careful not to damage the disc. Wash the stem, disc, and handle with mild detergent. Use a nylon brush inside the valve body and tangent tube. Reassemble and flush with clean water.

Is the kettle NSF certified?

The manual indicates that the kettle must be sealed to the floor with silicone or equivalent sealant to fulfill NSF requirements. Proper installation is necessary for compliance.

What are the dimensions of the KLS-30DS?

Key dimensions: A (width) = 24 in (610 mm), B (depth) = 20 in (508 mm), C (height to top of legs) = 37 in (940 mm), overall height (J) = 62.88 in (1597 mm). For complete dimensions refer to the manual.

Can I replace the safety relief valve?

Only qualified personnel should service the safety relief valve. It is set to relieve excess pressure and should not be altered. If replacement is needed, contact Blodgett service.

What type of food products are suitable?

The kettle is designed for liquid or semi-liquid foods to ensure complete contact with the heated bowl surface. Ideal for soups, sauces, stews, and similar products. The high steam pressure allows faster cooking at higher temperatures (e.g., 30 PSI = 274°F / 135°C).

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.
3. Slowly turn the steam control valve ON to full open position (counter clockwise).
4. The water or food should boil 2 - 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.
