GDF28 Dispenser

INTRODUCTION

The Dispenser is a compact automated system that replaces manual basketing of frozen french fries. The Dispenser automatically weighs 12 ounce (350 gm), 16 ounce (450 gm) or 24 ounce (700 gm) loads of frozen fries and dispenses them into custom fry baskets.

The Dispenser's Hopper holds 42 lbs. (19 kg) of frozen french fries prior to basket loading. A rotating Dispenser Drum inside the Hopper transfers the frozen fries onto the Accumulator Doors where a weight sensor accurately weighs the fries.

Empty baskets are manually placed on the Upper Guide. The baskets slide under the Accumulator Doors where fries are dispensed into them. The Basket Lift then lowers the filled baskets onto the Lower Guide where the baskets wait to be picked up by a crew person.

INTENDED USE

The GDF28 Dispenser is intended to dispense only frozen french fries. All food should be stored and handled according to industry recommendations. The GDF28 Dispenser is not intended to be used for storage of food and should be cleaned regularly as described in the manual in order to avoid spoilage and contamination.

HAZARD COMMUNICATION STANDARD (HCS) The procedures in this manual may include the use of chemical products. These chemical products will be highlighted with boldface letters followed by the abbreviation (HCS) in the text portion of the procedure. See the HCS Manual for the appropriate Material Safety Data Sheets (MSDS).

NOTE: This equipment is manufactured in the

U.S., therefore all hardware measurements are in English, and the metric conversions stated are approximate.

ADAPTIVE WEIGHT TECHNOLOGY

This Dispenser utilizes adaptive weight technology. This allows the optimal parameters used in weighing to be learned for the product being dispensed. It varies the Drum rotation speed to keep the rate of weight gain constant. It takes between 10-20 cycles for the Dispenser to learn the product. The settings will not be changed when the Dispenser is turned OFF, only when the food properties change.

DAILY SET-UP

1. Verify that the Power Switch is in the OFF position.

2. Plug the Power Cord into a wall outlet.

3. Load the Hopper with frozen french fries. DO NOT SHAKE OR DROP the fries into the Hopper (refer to "LOADING THE HOPPER", page 8).

4. Turn the Load Select Switch to the desired load weight.

5. Fill the Upper Guide with empty Custom Baskets.

6. Turn the Power Switch to the ON position (illuminated). Electric motors will orient themselves to starting positions and the dispenser will initiate the filling process.

7. Use filled Baskets from the Lower Guide for Fry production.

8. Return empty Baskets to the Upper Guide for refilling after the cooking cycle is complete.

LOADING THE HOPPER

To achieve optimum fry yield and the most consistent basket loads, it is important to use the following technique for loading frozen fries into the hopper. Depending on your fry supplier, you will receive your french fries packaged in boxes of six pounds each, or bags of six pounds each. These bags or boxes will be packed six to a case. The hopper will accept one full case plus one bag or box of french fries (42 lbs. or 19 kg).

For each bag or box of french fries:

1. Remove the bag or box of french fries from the case. Be careful not to crush the fries.

2. Open the top of the bag or box completely. NOTE: If your supplier uses bags, be careful that the top is

fully open. If it is partially open, the bag may retain fries.

3. Hold the opened end of the box or bag closed with your hand and lay it in the hopper with the opening toward the side opposite of the diverter.

4. Release the opened end of the bag or box.

5. Empty the bag or box into the hopper by pulling it evenly toward the Diverter. When adding multiple bags of fries, alternate the placement of the bag or box in the hopper opposite of the previous bag or box. The second bag of fries should be emptied into the Hopper with the opening toward the Diverter, and pulling it evenly toward the Hopper Wall opposite the Diverter.

NOTE: This criss-cross loading method assures an even distribution of fry lengths in the Hopper and the Baskets.

NOTE: Do NOT shake or drop fries from the bag or box into the Hopper.

NOTE: If the loading is done correctly, you should be able to leave a uniform layer of fries in the hopper by simply pulling the bag or box across the hopper and then out of the hopper.

6. Repeat steps 1 through 5 until the hopper is full.

NOTE: Do NOT fill the hopper past the top.

7. Close the lid on the hopper by engaging the hook at the

back of the hopper, and setting the lid down

DAILY CLOSING

1. Turn the Power Switch to the OFF position.

2. Remove all Baskets from the upper and Lower Guides. Discard and record the uncooked fries.

NOTE: During the last few hours of the day, you may want to keep only two or three bags of french fries in the hopper and run the dispenser in SINGLE mode, to minimize waste.

3. Remove the Hopper Lid by lifting it UP and BACK to unhook the tab.

4. Hang the hopper lid on the front of the hopper, by hooking the tab on the lip of the hopper.

5. Discard and record any fries remaining in the Hopper at closing.

6. Check that the Accumulator Doors are empty of fries.

7. Disconnect the Power Cord from the electrical outlet

8. Remove the Diverter by grasping it and pulling it UP.

9. Slide the Locking Pins outward to release the Hopper.

10. Remove the Hopper (and the Dispenser Drum inside) by pulling the Hopper OUT and AWAY from the Hopper Support Bars.

11. Remove the Upper Guide assembly by lifting the RIGHT end and sliding it to the LEFT.

12. Remove the Lower Guide by lifting it straight UP.

13. Remove the Drip Tray by lifting it from the Basket Stop end and sliding it from under the saddle.

14. Take the hardware removed from the Dispenser to the back sink. Wash it in a hot solution of McD APSC (HCS), rinse with clear water, sanitize and allow to air dry.

15. Roll the dispenser out from the wall, so that you can clean behind it and underneath it.

NOTE: Do NOT roll the dispenser to the back sink for cleaning, this will cause unnecessary wear on the dispenser and possible premature failure.

16. Wipe down the dispenser with a hot solution of McD APSC (HCS) and water. Repeat wipe-down with clear water, sanitize and allow to air dry. NOTE: DO NOT SPRAY DOWN THE DISPENSER. It is not sealed against jetting water and contamination may get into sensitive components. SPRAYING MAY VOID THE WARRANTY!

17. Reassemble the dispenser.

18. Roll the dispenser back into place.
