Case Studies – Food Processing

Food Processing

Nowhere in California are the new regulations more aggressive than in the San Joaquin Valley. In this region agricultural food processing plants have already experienced multiple compliance deadlines. The case studies here examine customer applications and key challenges.

J.R. Simplot Company

SCR Project & Control Retrofit
Helm, CA
Boiler and gas train upgrades result in high efficiency and increased safety.
J. R. Simplot Company is one of the largest privately held food and agribusiness companies in the nation. The Lathrop-Helm facility produces high quality nitrogen and phosphate fertilizers for professionals in agriculture, the turf trade, nurseries, the feed business, and industrial applications.
The plant operated a 50kppm IWT auxiliary boiler to start their main boiler processes. Once the main boiler process generates enough heat to become self-sufficient, the auxiliary boiler goes off-line. The auxiliary boiler had been in use since the 1950s, and required emissions control improvement as well as upgrades to meet current code and safety requirements.
J.R. Simplot opted for a retrofit and upgrades to meet their requirements and contacted R.F. MacDonald Co. to assist with their equipment project. Read more

Boiler Case Study - Food Processing - Teasdale Foods

Teasdale Foods

70,000pph, 5ppm NOx BPS Steam Plant
Atwater, CA
New steam plant with SCR technology provides overall processing efficiency.
With roots traced back to the 1930s, Teasdale Quality Foods has been providing high quality, delicious products for more than 70 years. Located in the heart of California, they are recognized as a leader and innovator providing retail, food service, and industrial customers with a full line of Hominy and Dry Soak Beans.
Over time, their steam plant slowly deteriorated until they were running their entire operation on a single boiler with no economizer. As a result, the production process became inefficient and consumed high quantities of excess air. After entering negotiations with a private equity firm to sell their company, Teasdale Quality Foods set a goal to upgrade their boiler to meet current and future air quality regulations, but was unsure where to begin.

Boiler Case Study - Food Processing - JG Boswell

J.G. Boswell Tomato Retube

Boiler Retubing
Buttonwillow, CA
Retubing of tomato processing boiler maintains harvest schedule.
J.G. Boswell is a tomato processing company that uses two Cleaver-Brooks industrial water tube boilers to process approximately 4,800 tons of fresh tomatoes per day. When the tomatoes are brought in from the field, they’re flash steam cooked and mashed into a paste. The paste is then packed into large wooden crates and shipped to the end user customer.
The boilers used for the flash steaming process are constantly exposed to the elements, so over time moisture can soak through the insulation and oxidize the tube sidings. Eventually, one of the deteriorated tubes ruptured, leaving the boiler inoperable just weeks before the harvest season. J.G. Boswell needed the whole side of their boiler retubed in less than two weeks, or they’d fall behind schedule and miss crucial deadlines. Read more

Boiler Case Study - Food Processing - Leprino Foods West

Leprino Foods Lemoore West

Install SCR System
Lemoore, CA
New boiler using selective catalytic reduction (SCR) to meet requirements.
Leprino Foods, is a world leader in premium-quality cheese manufacturing and the largest U.S. exporter of whey products. Leprino mozzarella cheese, cheese blends, and pizza cheese are made especially for pizzeria and foodservice operators, frozen food manufacturers and private label cheese packagers.
The Lemoore facility was planning a large expansion to a 500,000 sq. ft. cheese-making and whey-processing facility that is one of the world’s largest cheese plants today. This expanded plant would require additional steam for processing. R.F. MacDonald Co. worked in conjunction with the facility engineers to deliver and install a boiler system that would meet the plant’s production demands as well as the new Ultra-Low NOx requirements of the San Joaquin Valley Air Pollution Control district.

Boiler Case Study - Food Processing - Hilmar Cheese

Hilmar Cheese Company

Boiler Retrofit and Replacement
Hilmar, CA
Retrofit and replace existing boilers to meet low NOx emissions requirements.
The Hilmar Cheese Company site in California annually produces more cheese from one site than any other manufacturer in the world. The production facility converts over 20,000,000 lbs per day of high-quality milk into a variety of cheese products. They specialize in the production of cheddar and natural American cheeses utilized by private label and national brand companies, producing more than 1.9 million pounds of cheese each day.
The plant was required to lower their NOx emissions to comply with the San Joaquin Valley District regulations. In addition, the customer wanted to use this opportunity to also increase their existing steam capacity. Read more

Food Processing Boiler

ConAgra Foods

Boiler Replacement
Modesto, CA
Replace existing boiler to meet low NOx emissions requirements.
ConAgra Foods is one of North America’s largest packaged foods companies with products available in supermarkets as well as restaurants and food service establishments. One process involves a DL68 Watertube Boiler that supplies steam to a frozen vegetable facility for the Flash Carrot Peeler. For this specific process, carrots are loaded into a bin that rotates slowly while being quickly pressurized to 200 PSI and then vented to explode the skin off the carrot. The carrot peeler would require 20,000 PPH for 10 seconds every minute and a half. This cycle is repeated 24hrs a day.
The DL68 Watertube Boiler was 30 years old and had trouble handling the drastic change in load. In addition, new regulations imposed by the Air District retrofit rule would now require NOx emission levels of 9ppm. Read more

Boiler Case Study - Food Processing - JG Boswell Tomato

J.G. Boswell Tomato Company

Boiler Retrofit
Buttonwillow, CA
Retrofit existing boilers to meet low NOx emissions requirements.
Two Cleaver Brooks Industrial Watertube boilers are responsible for plant operations that include processing approximately 4,800 tons/day of fresh tomatoes with a 240,000 pph peak steam demand at 350 psig saturated conditions. The boilers were originally supplied in the year 2000 with burners designed to meet the then current San Joaquin Unified Air Pollution Control District Rule 4306 requiring units over 20 mmbtu/hr to operate at less than 9 ppm NOx.
In 2007, the Air District began workshops with the intent to further limit NOx emissions. With this new rule pending, J.G. Boswell approached R.F. MacDonald Co requesting a solution that would allow the boilers to operate below the new limits of 6 ppm NOx and 50 ppm CO and to review energy saving options related to this upgrade. Read more
