Should You Supersize Your Mogul?
Discussion Period (Q&A) Should You Supersize Your Mogul? Tim Murphy Ferrara Pan Candy Co. T he decision to purchase a “jumbo mogul,” as opposed to a standard size, is one that should be given serious consideration.This paper will compare the upscaling in size of three mogul systems: Makat, Winkler + Dünnebier, and NID. Information on the Makat was taken from the upscaling experiences of Charles Fox, director of engineering, Brach and Brock Confections. I will relate the experiences that Ferrara Pan Candy Company had with the upscaling of a NID mogul system. Finally, the manufacturer has provided information about the Winkler + Dünnebier mogul. The specific areas of comparison will be production, depositing systems, starch drying systems, staffing and the mogul itself. PRODUCTION There are few differences between the two sizes of moguls. The major change is simply the difference in the size of the depositing board. Specifically, the printable area of the depositing board has increased from 458 square inches to 763 square inches. This 66 percent increase in the area of the starch board does not necessarily represent an equal increase in production volume.The production increase will be based on three factors: the configuration of the mold pattern of the board, the quantity of cooked candy the cooking system can deliver and the board-per-minute speed of 53rd PMCA Production Conference, 1999 the starch mogul. For example, the increase in production for an individual board of starch jelly beans at Ferrara Pan Candy Company worked out to about 60 percent, based on the mold pattern. This represented a production increase from 4,200 pounds per hour to 7,500 pounds per hour. Space has to be the first consideration. Ferrara Pan found the change to a jumbo mogul a lesson in space consumption. The standard mogul, its oiler, sander, dry rooms and service area took up an area of 5,760 square feet.The jumbo mogul was designed with the same list of equipment to fit into an area of 6,336 square feet. Its predeposit mixing and cooking systems are significantly different in their square-footage requirements. The floor area requirement for the standard system is 1,778 square feet, but 2,880 square feet are required for the jumbo system. The predeposit equipment lists for both systems are the same. They include the following: • Powder starch feed hopper. • Dry sugar hopper. • Regular conversions corn syrup tank and feed system. • High DE corn syrup tank and feed system. • Batch mixing tank. • Colloid mixing tank and feed system. • A heated mixing tank prior to cooking. • Two buffer tanks. Murphy has held the position of vice president of quality control at Ferrara Pan since 1992. He began work there in 1981. Prior to this appointment he was employed at A.E. Staley Manufacturing Company. Murphy is an active member of the American Association of Candy Technologists and the National Confectioners Association. Tim Murphy 153 Should You Supersize Your Mogul?

THE STARCH BOARD Brach and Brock Confections was the first user of the jumbo-sized mogul in the United States and faced the problem of developing the starch board jointly with the starch-board manufacturing company. Charles Fox stated that he had reservations concerning the tray deflection. There were two issues. First was the exaggeration of the upward curve of the starch board due to the expanded width of the board, which would cause a poor print. This turned out not to be the case, as there was no noted print distortion. The second issue was that the starch board would sag if unsupported, causing instability of the stack. A center support was added to the Brach and Brock starch board and a support was added to the mogul. Ferrara Pan, in turn, went further by adding two more supports across the length and four bead supports across the width of the starch board. In comparison, the starch board of the standard-sized mogul has no supports but does have the slight upward bow. Ferrara Pan has experienced no significant difference in the life expectancy of the two sizes of boards. Although not in violation of OSHA regulations, a noted drawback to the expanded board width is that occasionally boards have to be removed from the mogul. The weight of the starch board, filled with starch and candy (approximately 27–30 pounds), coupled with the exaggerated width requires greater dexterity from the mogul operator than is experienced with the standard-sized board. 154 The costs for the two sizes of boards are in the $9–$10 range for the standard and the $14 range for the jumbo. THE COOKING SYSTEM For Ferrara Pan, the cooking system of the jumbo mogul presented some new innovations. Our standard system uses one cooker that contains two 108-foot copper coils. The maximum volume output for our standard mogul’s cooker is 7,500 pounds per hour.The jumbo system uses two cookers, each containing a single 128-foot stainless steel coil. The output for the larger system is 13,000 pounds per hour.The advantages with stainless steel are that it is easier to clean and it is resistant to attack from the acids that are in many of the formulas.The disadvantage of the stainless steel coil is that it requires more steam pressure to achieve the same cook. For starch jellies, we have found the stainless steel coil requires 110 psi, while the copper coil only requires 95 psi to achieve the same cook. The volume of steam directly relates to the quantity of candy that the steam is cooking.Another area of energy increase is that there are two 5-horsepower motors driving the pumps on the larger stainless steel coils of the jumbo system, in contrast to the two 3-horsepower motors operating the smaller standard system. THE JUMBO MOGUL It has been observed that the jumbo moguls tend to operate more quietly than the standard-sized moguls, which was not expected. Charles Fox attributed this decrease in noise to the heavier board weight and less angular displacement caused by slight differences from misaligned board pushers.At Ferrara Pan, we noticed that the larger mogul operates smoothly at 30 boards per minute. The standard-sized mogul can achieve this speed; however, it appears to run more smoothly at 28 boards per minute. Fox stated that the Makat operates quietly and efficiently at 30 boards per minute. Peter Lindner of W+D has stated 53rd PMCA Production Conference, 1999 Should You Supersize Your Mogul? that their jumbo mogul operates comfortably at 32 boards per minute. The jumbo mogul’s production is maximized when depositing one product at a time with minimum changeovers, since making changeovers has become a more difficult task. One of the problem areas is the difficulty in handling the increase in physical size of the nozzle plates and moldboards. The larger coils, tanks and color-flavor-acid systems have doubled the time required to clean and sanitize the candy mixing and cooking system. With the increased output it is necessary to use larger systems to handle the outflow of the candy. Ferrara Pan chose to go with a 10foot oiling drum and two standard sanders. The jumbo oiling drum is twice the size of the drum used on the standard mogul. The increase in size is necessary to achieve the required retention time for candy to be oiled properly. It is necessary to use two sanders as opposed to a single unit, like the oiler, because it is beneficial to reduce the amount of time the candy pieces tumble against one another, thereby rubbing off the sugar or sugar-acid coatings. In comparison, Brach and Brock custom-built their own oiling drum instead of using a commercial drum. Ferrara Pan uses a manual transfer of the stack of starch trays from the end of the mogul to the drying room. There are two stacks, 60 boards high, on the jumbo system. The standard system utilizes two stacks of 50 trays.The advantage of increasing the number of trays per stack is that less square footage of storage space is required in the drying rooms. The starch boards have been reduced by one-fourth of an inch in height for the jumbo system. This reduction has made the jumbo stack of starch boards only nine inches taller than the standard. The headspace in the dry rooms had to be adjusted to accommodate the nine-inch increase. 53rd PMCA Production Conference, 1999 THE DEPOSITING HEADS The most significant change Ferrara Pan encountered with the purchase of the jumbo mogul is the lateral deposit head. The standard-sized moguls that Ferrara Pan operates all have swinging-pendulum depositing heads in which the jacket of the depositing hopper is heated with hot water but the depositing head is not. The head on the depositor of the jumbo mogul can be heated, allowing for higher solids to be deposited. A second advantage of this depositing head is the synchronization with the starch mold to deposit directly into the center of the mold cavity. The older standard-system depositing head was also on a pendulum that followed the mold; however, it swung up and out, away from the starch mold. This system did not allow as precise targeting of the deposit. The lateral deposit head is available on all sizes of moguls from NID. W+D offers a similar type of depositing system with their moguls. Makat’s depositing system is stationary; the moldboard stops under the depositing head and is filled, all in one shot. The Makat also has a stainless steel rotary valve and is capable of a large array of color combinations with its programmable slides. The most signifiant change encountered with the purchase of the jumbo mogul is the lateral deposit head. STARCH DRYING It is recommended that 100 percent of the starch be conditioned and dried. With the increased board size and speed of the jumbo mogul, the starch drying systems have to handle 50 to 60 percent more starch than the standard-sized mogul. Ferrara Pan is using a system which allows the starch to be passed three times across an airflow for heating and also three times for cooling within two starch drying boxes. The difference between the jumbo-sized starch dryer and the standard-sized is the area of the starch bed.The standard-sized bed is 11 feet wide by 30 inches deep. The jumbo-sized box is 141⁄2 feet wide by 36 inches deep. The jumbo-sized mogul has a square footage 155 Should You Supersize Your Mogul? There are advantages and disadvantages to upscaling to the jumbo mogul. Production has increased with the jumbo system 60 percent. increase of 66 percent in board area; however, it is only a 60 percent increase in air volume due to the reduction in the board height. Therefore the jumbo mogul has a 60 percent increase in drying air volume to match the increase in the starch volume. The Makat system, utilized by Brach and Brock, uses a similar type of drying. However, instead of three passes in one box, they use six independent starch drying boxes: three independent boxes used for drying and three independent boxes used for cooling. Each of these boxes uses only a single pass of air. The Winkler + Dünnebier starch drying system is quite different from NID’s and Makat’s. Warm preconditioned air is mixed with the starch within a drying tube. From there, a multipocketed filter separates the starch from the moist air. The starch then goes to a cooler, which is different from NID’s and Makat’s cooling systems. The cooler is a water-jacketed trough housing two cooling conveyer screws. A water/glycol solution is used to cool the metal plate of the trough as well as the conveyers. An advantage of using the screw conveyers as the cooler is in eliminating the introduction of outside air, preventing the remoistening of the starch after it is dried. Following are two other features that differentiate the moguls: Starch Tray Tipper. The Makat and the W+D utilize a 180° board tipper. In comparison, the NID utilizes two sets of arms. One set turns over the starch board. The second set rights the board. The Destarching Systems in the Starch Buck. The NID and the Makat both use rotating drums to remove the candy.The NID uses a single drum.The Makat uses multiple drums to destarch the candy.The W+D uses a twotiered sieve to destarch the candy.The sieves are removable for cleaning. STAFFING To staff the jumbo mogul Ferrara Pan uses seven people, as opposed to five in the 156 standard mogul. The increase comes from the use of two individuals in the cooking area, as opposed to one in the standard, and two individuals filling the candy boards, with only one in the standard mogul. The mogul operation position and the palletmoving positions remain the same. CONCLUSION There are advantages and disadvantages to upscaling to the jumbo mogul. Production has increased with the jumbo system 60 percent. The design of the depositing systems has improved. However, these design improvements are available on all new moguls regardless of size. Starch drying systems, while innovative, remain energy neutral, showing no advantage with an increase in size. Staffing required a 40 percent increase in personnel to handle the 60 percent increase in production. And finally, the jumbo mogul, producing 60 percent more product, operates faster, and more smoothly than its standard counterpart. The jumbo requires almost twice as much time for cleaning and daily maintenance. WOULD WE DO IT AGAIN? When Charles Fox was asked, “Would his next purchase of a mogul be a jumbo?” he replied, “Given the increased productivity in terms of pounds per man-hour and the relatively small differential capital cost, I believe that any future mogul purchases would be jumbo-size machines.” He further explained that it was an economical way of acquiring future capacity because it is not necessary to operate the starch mogul at maximum speed. When Bernie Woziwodzki, chief of the engineering department at Ferrara Pan Candy Company, was asked the same question, he replied, “Yes, I would buy a jumbo. I am thinking about replacing a standard with a jumbo!” ■ 53rd PMCA Production Conference, 1999 The Pick SC7-3 Candy Cooker The Pick Pilot SC 3 Gerber Mexico Gerber Mexico REMOTE ELECTRONIC CONTROLLER TO DCS PREMIX KETTLE SCV PI I SEPARATOR FILTER P STEAM INLET TI 180°F T OPTIONAL STATIC MIXER PD PUMP PICK SANITARY HEATER RTD BPCV (TIED TO HI TEMP ALARM) DIVERT VALVE FLASH CHAMBER PUMP COLOR & FLAVOR POT MOGUL HOPPER MOGUL HOPPER MOGUL MOGUL HOPPER CONFECTIONERS G THIN-BOILING STARCH PRESSURE COOKED SUGARED JELLIES Ingredients: Sweetose® 4300 corn syrup (Staley)..........234.0 lb Granulated sugar.................................160 .0 STALEY® confectioners G starch................54.5 Water................................................ 58.0 Total............... 506.5 Procedure: 1.
