One of Brakes’ many specialty divisions, Creative Foods Ltd., makes prepared frozen meals, sauces, soups and desserts for the U.K.’s foodservice and catering market. This includes restaurants, pubs, hotels, schools, hospitals, automotive service stations and travel and leisure facilities. It provides its foods in a variety of formats for caterers to cover different options, like individual- and multi-portion meals, in-pouch and foil-tray varieties. The company also produces a range of individual sauce pouches for serving with meat, fish, pasta or vegetables. Quick and easy to use, caterers re-heat, pour and serve.
All of Creative Foods’ products are frozen immediately after production, the freezing process acts as a natural preservative, allowing the company to increase the amount of fresh ingredients in its products.
Many of the company’s entrees include cooked pasta, a culinary trend that is gaining momentum in the U.K. Recently, the company made the move to upgrade its process line for cooking pasta. It was looking for equipment that was diverse enough to handle all types and shapes of pasta - particularly long pastas such as fettuccine, linguine, tagliatelle and spaghetti. These long pastas typically are difficult to process because they tend to stick together, damaging the product quality and increasing waste.
This is a common problem for several U.K. processors cooking long pastas because most food manufacturing facilities use the batch system for cooking, quenching and chilling.
Using the batch system involves a basket of pasta being dropped into a tank of hot water where it stays until it is cooked. The basket then is lifted out and the cooked pasta is put into another tank with cold water where it is quenched to take the heat out of it - but the temperature reduction in this tank does not reach the desired chilled temperature for the pasta. So, the pasta is then put into a third tank of chilled water which brings the pasta down to below 41 degrees F, the desired range.
“We do quite a wide range of products incorporating different pastas,” says Howard Batey, factory general manager at Creative Foods. “Ninety percent of the time we are running pasta. The remaining 10 percent is vegetables, like carrots and potatoes, and a small amount of rice.
“An increasing part of our business is in the long pastas like spaghetti, linguine and tagliatelle,” continues Batey. “We could not find a system that could adequately cook and cool these pastas at the volumes we were processing without it sticking together. So, we resorted to buying-in our long pasta, precooked and chilled.
“We were cooking our shaped pasta in steam-jacketed vessels,” Batey explains. “We were aware that this method did not give us as much control in terms of timing of the cooking and cooling because it was being done manually.
“Additionally, our batch cooking and cooling had limitations on how much pasta we could process at any one time,” says Batey. “We were struggling to keep up with our production demands, trying to keep all of our lines fed with cooked pasta.
“We were looking for equipment that could not only cook, but that could also cool, so we could maintain better control over the entire process,” Batey continues. “We needed very fast cooling, so we could get more consistent product quality. We could not find any equipment that could cook the long pastas without the strands sticking together. That was the single biggest factor we were looking at resolving with automation.”
The pasta cooking/cooling solution that Creative Foods eventually selected is called Clean-Flow, developed by Lyco Manufacturing, Columbus, Wis. The system utilizes a rotary drum that provides water injection for agitation to keep the product in uniform suspension while moving through the unit.
The Clean-Flow design incorporates an accurately made screw that is encapsulated by a stationary wedge-wire screen. The tolerance between the screw and the screen is less than a grain of rice. The water agitation injected through the screen keeps the product off the floor of the screen, where it is maintained in total suspension. Damage to fragile product is a fraction of one percent, even less than in a conventional rotary drum set-up.
Clean-up time is dramatically reduced in the Clean-Flow design because the screw is totally exposed for cleaning. During clean-up, the screen is released from its fixed position, and is continually rotated 360 degrees around the screw, alternately exposing the interior and exterior of the screen to clean-in-place manifolds located in the cover of the machine. The screw can be rotated at the same time as the screen, again exposing all surfaces to the cleansing water sprays. Clean-up times are reduced as much as 75 percent compared to conventional rotary drum blanchers.
Clean-Flow significantly has minimized the cleaning changeover time on short runs to as low as 20 minutes. This allows for an increased number of changeovers per shift, giving maximum flexibility and efficiency to food processors.
Having a truly continuous process is something that is a somewhat new in the U.K. The flexibility of running multiple products throughout the production day at different temperatures and at different retention times is a unique feature to processors worldwide.
Consistent process parameters for temperatures and recipes automatically controlling the pasta cooking and cooling hour after hour has completely out-performed the batch method Creative Foods formerly used.
Food processors are leaning toward shorter runs and wider product selections with increasing concern about quick change-over, faster clean-up and turn-around times. On a standard commercial cooker/cooler rotary drum, it would typically take two hours to complete the cleaning for a line transition. That makes it impractical to execute more than one transition per eight-hour shift. Creative Foods’ cooking and cooling line meets the needs of quick change-over by speeding up the sanitation process, which provides the flexibility to run a variety of different products daily on the same line.
“The attraction to Clean-Flow, for us, was the flexibility,” Batey says. “The internal parts can be cleaned much more easily, which means changing between different products within the same day could be done more quickly. Our plans were to process relatively short runs of different types of product. This meant putting through different shapes and types of pastas, and even completely different products within the same day, such as switching from processing vegetables to pasta.
“The quality of our pasta products has improved dramatically - in part because we now have absolutely consistent cooking times, and are not relying on manual intervention - and also because the cooling cycle is now immediate,” explains Batey. “We have almost totally eliminated product damage, and we are running our long pasta through the system as well, no longer buying it out. The line is much gentler on the handling of the pasta, particularly with the more delicate varieties. We are processing approximately 2,640 pounds of pasta per hour through the Clean-Flow line, and some days we run the line for 16 hours continuously. It is running very smoothly.”
In the U.S. alone, the frozen entree market is a $6 billion dollar a year industry, with the average American cooking and eating a frozen meal about six times each month. New and healthier frozen food products, touting the addition of whole grains, the removal of trans-fats and the use of organic ingredients, are continuing to keep consumers interested. Complementing this is the growing trend in ethnic frozen entrée variations.
Internationally, the desire among consumers for convenience and wholesome, home-cooked meals, especially with families, is at an all-time high and shows no signs of waning. The U.K. is no exception here, proving to be a leading market for ready meals, both chilled and frozen. Smart food manufacturers, such as Brake Brothers, quickly are realizing that the switch to more efficient automated systems for processing these entrees is critical to capturing and maintaining market share in this category.
