Pet Food Producer Saves Over $20,000/yr in Energy Costs Alone By Replacing Old Jacketed Kettles and Sparge Systems

A major manufacturer of pet food wanted to replace a jacketed kettle and a live steam cooker with a Direct Steam Injection 3-A heater system to heat, mix and then cook meat slurry for dog food. They needed to maintain thorough cook and product quality as well as comply with governmental sanitary standards.

The pet food slurry needed to reach 195°F ± 1°F for a specified period of time. The aging equipment needed constant maintenance and the steam hammer produced by the equipment jeopardized other plant equipment and safety. It was also very inefficient and wasteful of time and energy.

The solution included replacing the sparged hot water tank and jacketed kettle with a Sanitary Hydroheater® model A210 to heat and cook the meat slurry to 195°F precisely and to within 1°F. The Sanitary Hydroheater is placed in-line and supplied with plant steam and air as the cold slurry is pumped through the heater where it mixes with steam and is cooked in one pass to 195°F. Because of the turbulent mixing with high velocity steam, the Hydroheater is selfcleaning and needs little maintenance. Meat slurry cook temperature stays to within ±1°F when flow rates are constant. This keeps product quality consistent and predictable.

The company is enjoying consistent product quality and is reaping the benefits of energy savings, maintenance savings and space savings. The heat load required in the old jacketed kettle process (based on 14 hour/day usage) was 90,126 BTU/min. Steam flow required was 95.1lbs/min. With the new Hydroheater, the steam flow required
is 79.9lbs/min. At a cost of $6.00 MBTU for energy, the company is saving $40,947/year in energy costs alone.
The company was also able to eliminate several pumps and mixers, saving them over $10,000/year as well as space savings. Even more dollar savings are realized because the maintenance of the current system is far less time consuming than the sparge tank, kettle set-up. More important to the company, however, is the fact that they are able to maintain the high quality of their product.

Operating Conditions:

Unlike heat exchangers or spargers, the Hydroheater is designed only for your process conditions and unique application. We need to know a few things about your conditions, such as temperature range, steam pressure, and flow rates to size a heater specifically for you. When you click on our application data sheet and fill in the information, we will contact you within one business day. After an initial conversation with a sales representative or one of our engineers, we will then provide you with a custom quote for the Hydroheater best suited for your process.
