Uniform impingement cooking increases safety & profits

As demand grows for higher production rates and a greater variety of fully cooked prepared foods, so does the concern over safety. Each and every piece of product must be fully cooked to ensure it is free of harmful micro-organisms. The speed and versatility of impingement ovens have helped processors meet these demands. Unfortunately, most ovens do not apply heat evenly, forcing processors to sacrifice yield for safety by "overcooking" to ensure all product reaches a safe core temperature.
Illustration of Airforce Plenums
Only AirForce has fans in plenums above and below the product for completely uniform cooking.

Heat and Control's AirForce is the only impingement oven that cooks uniformly across the entire product conveyor width. Air circulation fans located in plenums above and below the product belt develop completely uniform airflow to the product so each piece is cooked equally. Air velocities up to 9,000 fpm and precise control of temperature and moisture deliver short cook times, high yields, and excellent product browning.

PLC control provides ready access to multiple cooking recipes, ensuring repeatable settings, consistently uniform product, and fast changeovers. Oven cleaning, troubleshooting, and security levels are also controlled by the PLC.

Try using the AirForce oven at our Technical Centers. They are a great place to experiment with different cooking parameters. And we can combine the AirForce oven with our batter and breading applicators, fryers, flame searing, and grill mark branding equipment to give you greater production versatility and safety.  More Info   VideoVideos

New high capacity kettle chip fryer

MasterTherm Fryer batch frying potato chipsConsistently produce up to 500 finished pounds per hour of batch fried potato chips of almost any style with our new MasterTherm kettle Fryer (MTKF).

Cooking oil is heated gently and uniformly throughout the fryer by a thermal fluid heat exchanger which is immersed in the oil. Generous spacing between the heating tubes facilitates cleaning and eliminates areas where fines can accumulate. Each tube expands independently, greatly reducing damage caused by thermal stress. Tubes are electro-polished to simplify cleaning.

A full-length hood covers the kettle for safety and additional benefits: Heat is retained for high energy efficiency; steam blanketing the oil purges oxygen to prolong oil life; exhaust volume is far less than fryers using area hoods; a clean-in-place system reduces sanitation labor. An Oil Mist Eliminator is included to remove oil droplets from exhaust emissions.

Our proven screw jack hoist system safely raises the hood and heat exchanger for complete access inside the fryer. Potato slices are automatically agitated and removed from the fryer by our reliable Chip-Stirr paddle system. PLC control maintains a consistent temperature profile from batch to batch, and stores multiple product profiles for quick changeovers and repeatable product quality.

Single and multiple MKTF fryers are available with potato unloading, storage, washing, and peeling equipment, slice feeders, de-oiling centrifuges, seasoning applicators, conveying, inspection and packaging systems.   More Info   

C.J. Vitner boosts productivity 20% with new Ishida bagmakers!

Vitners, The Chicago Style Snacks Packaging over 2.5 million bags of snacks every week, C.J. Vitner Co. planned to increase efficiency of its busy packaging lines by replacing some of its older model bagmakers.

"In 2010 we purchased eight Ishida Atlas-222 baggers because of their proven capability and strong customer support from Heat and Control," explained Jerry Macrito, VP of Manufacturing. C.J. Vitner manufactures potato, corn, and tortilla chips, popcorn, and extruded snacks under the Vitner brand and for private label customers at their 135,000 sq. foot manufacturing plant in Freeport, IL.

Ishida Atlas Snack Bagmakers at Vitner's Snacks"The Atlas-222 baggers have helped us gain an average increase of 20% in productivity," says Macrito. "We have seen less downtime with an increase in speed and efficiencies." C.J. Vitner produces a variety of bag sizes, from 1/2 ounce up to 12 ounces, in polypropylene and foil films. Although packaging speeds with the Atlas baggers are now faster, Macrito says average product over-fill has been kept to less than 1 gram beyond declared weight. "Regardless of the product density, the baggers have performed favorably: scrap is less than 1% with film yields improving by 6%," says Macrito.

Capable of speeds up to 250 bags/minute, the Ishida Atlas-222 features unique rotary motion sealing jaws that produce tight end seals with all snack bag films. Back sealing is synchronized with film speed to create wrinkle-free vertical seals. Precise film tension, which is critical to trouble-free high-speed operation, is maintained using Ishida's real-time load cell tensioning system. To prevent product from entering seals, Atlas uses a unique stripping and bag inflating system. All functions are controlled from a simple color touch screen. "The user-friendly program and easy-to-read display have proven to make this an easy operation for our machine operators," says Macrito. "One operator is now able to run three baggers at once without reducing productivity."

"Installation and start-up was faster than we expected. The actual installation only took one day," notes Macrito. "Heat and Control was always available to answer questions and lend support if needed," he adds. All things considered, the new Ishida Atlas-222 bagmakers have improved packaging efficiency so well for C.J. Vitner, concludes Macrito, "they will completely pay for themselves in less than three years." More info   VideoVideos
