3.3 IMPORTANT INFORMATION REGARDING

CLEANING AND SANITIZING

Soft serve machines require special consideration when it comes to food safety and proper cleaning and sanitizing.

The following information specifically covers issues for cleaning and sanitizing frozen dessert machines. This information is meant to supplement a comprehensive food safety program.

Figure 3-2 IntelliTec2 Control

SOIL MATERIALS ASSOCIATED WITH FROZEN

DESSERT MACHINES

MILKFAT/BUTTERFAT – As components of ice-cream/ frozen custard mix, these soils will accumulate on the interior surfaces of the machine and its parts. Fats are difficult to remove and help attribute to milkstone buildup.

MILKSTONE – Is a white/gray film that forms on equipment and utensils that are exposed to dairy products.

These films will accumulate slowly on surfaces because of ineffective cleaning, use of hard water, or both. Milkstone is usually a porous deposit, which will harbor microbial contaminants and eventually defy sanitizing efforts.

Once milkstone has formed, it is very difficult to remove.

Without using the correct product and procedure, it is nearly impossible to remove a thick layer of milkstone.

(NOTE: general-purpose cleaners DO NOT remove milkstone.) This can lead to high bacteria counts and a food safety dilemma.

IT IS BEST TO CONTROL MILKSTONE ON A DAILY

BASIS BEFORE IT CAN BECOME A SIGNIFICANT FOOD

SAFETY PROBLEM.

In addition to food safety, milkstone can cause premature wear to machine parts, which can add to costs for replacement parts or possibly more expensive repairs if worn machine parts are not replaced once they have become excessively worn.

IMPORTANT DIFFERENCES BETWEEN CLEANING AND

SANITIZING

CLEANING vs. SANITIZING

It is important to distinguish between cleaning and sanitizing. Although these terms may sound synonymous, they are not. BOTH are required for adequate food safety and proper machine maintenance.

6

·

·

CLEANING

Is the removal of soil materials from a surface.

Is a prerequisite for effective sanitizing.

NOTE

An UNCLEAN surface will harbor bacteria that can defy sanitizing efforts.

·

·

Bacteria can develop and resist sanitizing efforts within a layer of soil material (milkstone). Thorough cleaning procedures that involve milkstone removal are critical for operators of frozen dessert machines.

SANITIZING

Kills bacteria.

Can be effective on clean surfaces only.

NOTE

Using a SANITIZER on an unclean surface will not guarantee a clean and safe frozen dessert machine.

PROPER DAILY MAINTENANCE:

The Only Way to Assure Food Safety and Product Quality

Proper daily maintenance can involve a wide variety of products and procedures. Overall, the products and procedures fall into three separate categories. (Please note that this is a brief overview intended for informational purposes only.)

1.

CLEANING – This involves draining mix from the freezing cylinder and rinsing the machine with water. Next, a cleaner is run through the machine.

Then, the machine is disassembled and removable parts are taken to the sink for cleaning.

2.

3.

MILKSTONE REMOVAL – Since most cleaners do not have the ability to remove milkstone, the use of a delimer becomes necessary. Although this procedure may not be needed on a daily basis, it will usually follow the cleaning procedure. It requires letting a delimer solution soak in the machine for an extended period. Individual parts are also soaked in a deliming solution for an extended period of time

(more about delimers in Additional Information).

SANITIZING – After the machine has been cleaned and contains no milkstone, the machine is reassembled. Then a FDA-approved sanitizing solution is run through the machine to kill bacteria.

The machine is then ready for food preparation.

·

·

·

As a recommended cleaner and sanitizer for your frozen dessert machine, STERA-SHEEN has proven to be one of the best daily maintenance products for:

CLEANING – Thorough removal of all solids including butterfat and milk fat.

MILKSTONE REMOVAL – Complete removal of milkstone.

SANITIZING – FDA-approved no rinse sanitizer for food contact surfaces.

ADDITIONAL INFORMATION

THE USE OF DELIMERS

A delimer is a strong acid that has the ability to dissolve milkstone. This type of chemical may become necessary once high levels of milkstone have developed. While these products are very effective for removing HIGH levels of milkstone, they are not ideal for two reasons:

1.

2.

PRODUCT SAFETY – Strong acids are dangerous chemicals. Carefully follow safety instructions provided with delimer products.

MACHINE DAMAGE – Strong acids will attack metal and rubber causing premature wear of parts. The use of a delimer needs to be closely monitored to avoid damage to machine surfaces and parts.

With proper daily use of STERA-SHEEN or its equivalent, there is no need for the use of a DELIMER.

·

DO NOT USE BLEACH

BLEACH HAS ABSOLUTELY NO CLEANING

PROPERTIES.

· BLEACH IS CORROSIVE. It will damage components of the machine causing premature wear and metal corrosion.

GENERAL PURPOSE CLEANERS

General purpose cleaners do not have the ability to remove milkstone. Milkstone will become a problem if not remedied with additional products and procedures.

THE USE OF CHLORINE TEST STRIPS

“Test strips” are used to determine concentrations of active chlorine in sanitizing solutions. To use the strips, tear off a small portion and submerge it into the sanitizing solution.

Then, compare the color change to the color key on the side of the test strip dispenser to determine the approximate chlorine concentration.

The ideal concentration of chlorine needs to be 100 ppm (as stated by the FDA).

NOTE

Follow the directions on the container for proper concentration.

Two main factors contribute to falling chlorine concentrations in a sanitizing solution.

1.

PRODUCT USE – As the chlorine in the solution is being used, chlorine concentrations fall.

2.

TIME – As time passes, small amounts of chlorine

“evaporate” from the solution. (That is why you can smell it.)

Sanitizing solutions should not be allowed to fall below 100 ppm chlorine. New solutions should be mixed once old solutions become ineffective.

3.4 DISASSEMBLY OF MACHINE PARTS

Before using the machine for the first time, complete machine disassembly, cleaning and sanitizing procedures need to be followed. Routine cleaning intervals and procedures must comply with the local and state health codes.

Inspection for worn or broken parts should be made at every disassembly of the machine. All worn or broken parts should be replaced to ensure safety to both the operator and the customer and to maintain good machine performance and a quality product. Check the wear line on the auger flights on a regular basis (Fig. 3-3) and replace as needed.

Frequency of cleaning must comply with the local health regulations.

B. DISASSEMBLY OF AUGER

1.

2.

Remove the front auger support and bushing.

Figure 3-5 Rear Seal Assembly

3.5 CLEANING DISASSEMBLED PARTS

Disassembled machine parts require complete cleaning, sanitizing and air drying before assembling. Local and state health codes will dictate the procedure required. Some state health codes require a four sink process (pre-wash, wash, rinse, sanitize, air dry), while others require a three sink process (without the pre-wash step). The following procedures are a general guideline only. Consult your local and state health codes for the procedures required in your location.

A.

B.

Prepare detergent water by mixing 2 oz. of Palmolive detergent or equivalent in 2 gallons of 90° to 110°F

(32° to 43°C) water. Place all parts in the detergent solution and clean with provided brushes.

Rinse all parts with clean 90° to 110°F (32° to 43°C) water.

3.9 SANITIZING

Sanitizing must be done after the machine is clean and just before the machine is filled with mix. Sanitizing the night before is not effective. However, you should always clean the machine and parts after using it.

NOTE

The United States Department of Agriculture and the Food and Drug Administration require that all cleaning and sanitizing solutions used with food processing equipment be certified for this use.

When sanitizing the machine, refer to local sanitary regulations for applicable codes and recommended sanitizing products and procedures. The frequency of sanitizing must comply with local health regulations. Mix sanitizer according to manufacturer’s instructions to provide a 100 parts per million strength solution. Mix sanitizer in quantities of no less than 2 gallons of 90°F to 110°F (32°C to 43°C) water.

Allow sanitizer to contact the surfaces to be sanitized for 5 minutes. Any sanitizer must be used only in accordance with the manufacturer’s instructions.

A.

B.

Prepare 2 gallons of sanitizing solution following the manufacturer’s instructions.

Install the mix inlet regulator into the hopper.

C.

D.

Pour the sanitizing solution into the hopper.

Make sure the display shows the freezing cylinder is off. If it is not, press the On/Off Left or On/Off

B.

Sanitize immediately before use.

Make sure the display shows the freezing cylinder is off. If it is not, press the On/Off Left or On/Off

Right button to turn it off.

Fill the hopper with at least 2.5 gallons of mix.

C.

D.

Place a container under the spigot and open the spigot to allow the mix to flush out about 8 ounces

(0.23 liters) of sanitizing solution and liquid mix.

Press the On/Off button for the cylinder.

E.

F.

Press the PUSH TO FREEZE button.

NOTE

After the drive motor starts, there is a 3-second delay before the compressor starts.

G.

When the product is at 75% consistency, the display will read “SERVE”. Open the spigot to dispense product.

NOTE

If the product consistency needs to be adjusted, use the Technician passcode and go to the Basic

Settings menu. Adjust the CutOut Consistency higher to increase the consistency or lower to decrease the consistency. Make adjustments in increments of 5 for best results.

H.

I.

The machine dispenses product at a reasonable draw rate. If the machine is overdrawn, the result is a soft product or a product that will not dispense at all. If this occurs, allow the machine to run for approximately 30 seconds before dispensing more product. A dispense rate adjustor is located under the header panel, to the immediate right of the spigot handle. Turning the knob counterclockwise will decrease the dispense rate.

Do not operate the machine when the MIX LOW message is displayed. Refill the mix container immediately.

NOTE

The machine has a standby and sleep mode. After a preset number of freezing cycles, it will enter the standby mode (followed by sleep mode) and remain there until someone draws product or presses the

PUSH TO FREEZE button. In the sleep mode, the machine will keep the product below 41°F (5°C).

Sleep modes do not take the place of cleaning and sanitizing. Federal, State, and local regulatory agencies determine frequency of cleaning and sanitizing.

3.11 MIX INFORMATION

Mix can vary considerably from one manufacturer to another. Differences in the amount of butterfat content and quantity and quality of other ingredients have a direct bearing on the finished frozen product. A change in machine performance that cannot be explained by a technical problem may be related to the mix.

Proper product serving temperature varies from one manufacturer’s mix to another. Mixes should provide a satisfactory product in the 20°F to 24°F range. Diet and lowcarb mixes typically freeze to proper consistency at higher temperatures.

When checking the temperature, stir the thermometer in the frozen product to get an accurate reading.

Old mix, or mix that has been stored at too high a temperature, can result in a finished product that is unsatisfactory. To retard bacteria growth in dairy based mixes, the best storage temperature range is between 33° to 38°F

(0.5° to 3.3° C).

CONDENSER CLEANING

The O231 has two condensers. An air-cooled or watercooled condenser and a condensing unit for the hopper.

The air-cooled condenser (and hopper condenser) is a copper tube and aluminum fin type. Condensing is totally dependent upon airflow. A plugged condenser, or restrictions in the louvered panel will restrict airflow. This will lower the capacity of the system and damage the compressor.

The condenser must be kept clean of dirt and grease. The machine must have a minimum of 3” (7.6 cm) of ventilation at the back of the unit for free flow of air. Make sure the machine is not pulling over 100° F (37° C) air from other equipment in the area.

The water-cooled condenser is a tube and shell type. The condenser needs a cool, clean supply of water to properly cool the machine, inlet and discharge lines must be 3/8”

I.D. minimum.

The air-cooled condenser and hopper condenser require periodic cleaning. To clean, refer to the following procedures.

A.

Visually inspect the condenser for dirt.

B.

C.

If the condenser is dirty, place a wet towel over the condenser.3

Using compressed air or CO

2

tank, blow out the dirt from the back of the condenser. Most of the dirt will cling to the wet towel.

D.

An alternative method is to clean with a condenser brush and vacuum.

NOTE

If the condenser is not kept clean, refrigeration efficiency will be lost.

4.12

EXTENDED STORAGE

Refer to the following steps for storage of the machine over any long period of shutdown time:

A.

Clean all the parts that come in contact with mix thoroughly with a warm detergent water. Rinse in clear water and dry all parts. Do not sanitize.

NOTE

B.

Do not let cleaning solution stand in the freezing cylinder or hopper during the shutdown period.

Remove, disassemble, and clean the front door, and auger shaft. Leave disassembled during the shutdown period.

C.

D.

Place the auger flights and auger support bushing in a plastic bag with a moist paper towel. This will prevent them from becoming brittle if exposed to dry air over an extended period of time (over 30 days).

For water-cooled machines that are left in unheated buildings, or buildings subject to freezing, the water must be shut off and disconnected.

Disconnect the water inlet fitting. The fitting is located at the rear of the machine. Run the compressor for 2 - 3 minutes to open water valve

(the front door must be attached for the compressor to run). Blow out all water through water inlet. Drain the water supply line coming to the machine.

Disconnect the water outlet fitting.

E.

F.

Press the Main Power On/Off button to turn the machine off.

Disconnect the machine from the source of electrical supply.

PREVENTATIVE MAINTENANCE

It is recommended that a preventative maintenance schedule be followed to keep the machine clean and operating properly. The following steps are suggested as a preventative maintenance guide.

The United States department of agriculture and the food and drug administration require that lubricants used in food zones be certified for this use. Use lubricants only in accordance with the manufacturer’s instructions.

A.

Daily checks

Check for any unusual noise or condition and repair immediately.

B.

C.

Monthly checks

Check the condenser for dirt and clean if necessary.

Quarterly Checks

Check drive belts for wear and tighten belts if necessary.

To return the machine to normal operation, any error causing condition must be corrected and the power to the affected freezing cylinder must be cycled. Turn the power to the freezing cylinder off then back on using the On/Off button of the affected freezing cylinder.

5.2 TROUBLESHOOTING

Error Code 2 - High Torque

If the control panel displays a High Torque Error

(E2), the controller has sensed that the drive motor is running at a high load for 10 or more seconds.

This may be due to the product consistency adjustment being set too high. Press the On/Off button for the cylinder to turn it off, wait until the product in the freezing cylinder thaws and then turn the cylinder back on. Follow the instructions in

Section 3 to reduce the product consistency by a few levels. If the error persists, contact your

Authorized Stoelting Distributor for further assistance.

Error Code 3 - Run Time

The Run Time Error (E3) occurs when the compressor runs continuously for an extended period. This error is generally caused by very low mix levels in the hopper or from product breakdown.

Another common cause results from a restriction preventing mix from entering the freezing cylinder.

Check the mix in the hopper. If the level mix is low, add mix. If there is a possibility that the mix has broken down, clean and sanitize the machine and replace the mix with fresh product.

Ice crystals in the hopper can clog the mix inlet system and prevent mix from entering the freezing cylinder. Thoroughly thaw mix per manufacturer’s recommendations. To check for ice crystals, pour a small amount of product from the mix container through a clean and sanitized sieve or strainer. If ice crystals are in the mix, check temperature of the walk-in cooler where the mix is stored.

In air cooled machines, the Run Time Error may indicate that airflow within the machine has reduced or stopped. Check the sides and top of the machine for anything that would restrict airflow.

If the error persists after attempting to clear it, contact your Authorized Stoelting Distributor for further assistance.

Error Code 4 - Clean

If the machine is left in the Clean Mode for more than 20 minutes, the control panel will display a

Clean Error (E4). This condition does not reflect a problem with the machine itself. The Clean Error has been programmed into the controller as a safeguard to protect the machine from potential damage caused by the machine being accidentally left in "Clean Mode". To clear the Clean Error, press the On/Off button for the cylinder to turn if off then back on.

23

Error Code 5 - Freezing Cylinder Sensor

The Freezing Cylinder Sensor Error (E5) indicates a failure of the barrel sensor or if the sensor is out of range. If the control panel displays an E5, press the On/Off button for the cylinder to turn if off then back on. If the error persists, contact your

Authorized Stoelting Distributor for further assistance.

NOTE

When the machine encounters a Freezing Cylinder

Sensor Error, the machine will continue to run using preset timers. This mode will allow the operator to continue serving product until the machine can be serviced.

Error Code 6 - Hopper Sensor (single hopper machines)

The Hopper Sensor Error (E6) will not occur on the machine.

Error Code 7 - Drive Motor

If the control panel displays a Drive Motor Error

(E7), the control does not sense current coming from the drive motor. Press the On/Off button for the cylinder to turn if off then back on. If the error persists, contact your Authorized Stoelting

Distributor for further assistance.

Error Code 8 - Cab Sensor

A Cab Sensor Error (E8) will not occur on the machine.

Error Code 9 - High Pressure Cutout

High Pressure Cutout Errors (E9) are usually caused by a dirty or inefficient condenser. If the control panel displays an E9 on an air cooled machine, check for proper air clearance around the machine. If there is an E9 on a water cooled machine check for proper flow from the water supply or kinks in the hoses.

If the error persists, contact your Authorized

Stoelting Distributor for further assistance.

Error Code 10 - Auxiliary Sensor

An Auxiliary Temperature Sensor Error (R10) occurs if the temperature sensor on the control board fails. Press the On/Off button for the cylinder to turn if off then back on. If the error persists, contact your Authorized Stoelting Distributor for further assistance

Error Code 11 - Prime Error

The Prime Error (E11) will not occur on the machine.

Error Code 12 - Left Hopper Sensor

The Left Hopper Sensor Error (E12) indicates a failure of the hopper sensor or if the sensor is out of range. If the control panel displays an E12, press the On/Off button for the cylinder to turn if off then back on. If the error persists, contact your

Authorized Stoelting Distributor for further assistance.

Error Code 13 - Right Hopper Sensor

The Right Hopper Sensor Error (E13) indicates a failure of the hopper sensor or if the sensor is out of range. If the control panel displays an E12, press the On/Off button for the cylinder to turn if off then back on. If the error persists, contact your

Authorized Stoelting Distributor for further assistance.
