Walk through almost any food manufacturing facility, and you'll find products that most people enjoy every day—creamy peanut butter, rich chocolate, smooth caramel, hearty soups, savory sauces, and perfectly whipped frostings. While each product has its own recipe, many of them share one common challenge: they're difficult to heat or cool without affecting quality.
For food manufacturers, temperature control isn't just about reaching a target number on a gauge. It's about protecting flavor, preserving texture, maintaining consistency, and delivering the same product every single time.
That's why so many processors rely on Votators®, or scraped surface heat exchangers (SSHEs). These specialized machines are engineered to handle products that traditional heat exchangers simply weren't designed to process.
Whether you're producing a few thousand pounds a day or operating around the clock, scraped surface heat exchangers help solve one of the biggest challenges in food manufacturing—moving thick, sticky, and delicate products through the production process without compromising quality.

Why Some Foods Need a Different Kind of Heat Exchanger
Not every food behaves like water or milk.
As products become thicker, contain more sugars or fats, or begin cooling, they often stick to heat transfer surfaces. Once that happens, efficiency drops, product quality suffers, and cleaning becomes more frequent.
Imagine trying to gently warm a pot of caramel on the stove. If you stop stirring, it quickly begins sticking to the bottom and can scorch before the rest of the batch reaches the proper temperature.
Now imagine doing that with thousands of pounds of product every hour.
That's essentially the challenge food manufacturers face every day.
Scraped surface heat exchangers solve this problem by continuously rotating scraper blades along the inside of the heat transfer cylinder. These blades gently remove product from the heated or cooled surface while simultaneously mixing it, ensuring fresh product is always in contact with the heat transfer area.
The result is faster, more uniform heating and cooling with significantly less fouling, scorching, or product degradation.
Food Products That Depend on Scraped Surface Heat Exchangers
Many of the foods lining grocery store shelves owe their consistency and texture to scraped surface heat exchanger technology.
Food manufacturers process thousands of high-viscosity products every day, including:
- Peanut butter
- Chocolate
- Caramel
- Sauces
- Gravies
- Salsa
- Pudding
- Custards
- Frostings
- Fillings
- Mashed potatoes
- Baby food
- Soup concentrates
These products may look very different from one another, but they share a common characteristic—they're challenging to process using conventional heat exchangers.
Without continuous scraping and mixing, many of these products can:
- Burn or scorch against hot surfaces
- Separate as ingredients settle or fats migrate
- Develop inconsistent textures
- Experience uneven heating or cooling
- Lose product quality before reaching packaging
Scraped surface heat exchangers help manufacturers avoid these issues while producing a more consistent product from batch to batch.
Why Texture Is Just as Important as Temperature
Consumers may never think about the engineering behind their favorite foods—but they certainly notice when something feels different.
A chocolate filling that's grainy.
A peanut butter that's too stiff.
A gravy that separates.
A pudding that's lumpy.
A frosting that doesn't spread properly.
Texture often determines how consumers perceive product quality, and maintaining that texture begins during processing.
By continuously scraping and gently agitating the product throughout the heating or cooling cycle, Votators help manufacturers create the smooth, uniform consistency customers expect.
The process also improves heat transfer efficiency, allowing processors to spend less time fighting equipment limitations and more time producing quality products.
Improving Efficiency Without Sacrificing Quality
Modern food manufacturers are constantly balancing production demands with quality expectations.
Scraped surface heat exchangers help support both objectives by offering several operational advantages, including:
- Consistent product temperatures throughout processing
- Reduced fouling and product buildup
- Improved heat transfer efficiency
- Gentle handling of delicate food products
- Better texture and product uniformity
- Longer production runs between cleaning cycles
- Reduced product waste
- Increased production reliability
For facilities running multiple shifts or continuous production, even small improvements in uptime and efficiency can translate into meaningful cost savings over the course of a year.
When Production Stops, the Clock Starts Ticking
Equipment doesn't always fail at a convenient time.
A processor may have customer orders scheduled, trucks waiting to load, and raw ingredients arriving daily. Every hour a production line sits idle creates additional pressure throughout the operation.
Unfortunately, replacing specialized processing equipment isn't always as simple as placing an order.
Many new scraped surface heat exchangers can have manufacturing lead times measured in months rather than weeks.
For food manufacturers, that's often time they simply don't have.
Sometimes the priority isn't replacing equipment forever.
It's finding a dependable solution that keeps production moving until the permanent replacement arrives.

Helping OEMs Deliver Solutions, Not Delays
At Genemco, we understand the relationships OEMs build with their customers.
If you've earned the opportunity to supply a new scraped surface heat exchanger, that's your business—and we're not interested in taking it away.
Instead, think of Genemco as an extension of your customer support strategy.
When long manufacturing lead times threaten your customer's production schedule, a quality pre-owned unit from Genemco can provide the bridge they need until their new equipment is ready.
It's less about replacing new equipment and more about protecting your customer's operation during an unexpected gap.
Your customer avoids prolonged downtime.
Your new equipment order remains intact.
And instead of having to tell your customer, "You'll have to wait several months," you're able to offer a practical solution that keeps their facility operating in the meantime.
Those are the moments customers remember.
Sometimes being the hero isn't delivering the equipment first—it's delivering the solution when your customer needs it most.
Why Food Processors Choose Genemco
For more than 37 years, Genemco has helped food manufacturers source quality pre-owned processing equipment that keeps facilities operating efficiently.
Whether you're responding to an unexpected equipment failure, increasing production capacity, or looking for a temporary solution while waiting on new equipment, our team understands the urgency behind every project.
When you partner with Genemco, you gain access to:
- A large inventory of quality pre-owned food processing equipment
- Faster availability compared to many new equipment lead times

- Equipment sourcing support for hard-to-find machinery
- Worldwide shipping capabilities
- A family-owned company committed to responsive customer service and long-term relationships
We know that every production facility has unique requirements, and our goal is to help you find equipment that fits your operation—not simply sell what's available.
The Right Equipment Can Keep Your Entire Operation Moving
Food processing is built on consistency.
Consumers expect every jar, carton, pouch, or container to taste and perform exactly like the last one they purchased. Delivering that level of consistency starts long before packaging—it begins with the equipment behind the process.
Scraped surface heat exchangers have become indispensable for manufacturers producing thick, temperature-sensitive, and high-viscosity foods because they help protect product quality while improving operational efficiency.
Whether you're a food manufacturer looking for a replacement Votator, expanding production capacity, or an OEM searching for a way to support a customer through extended lead times, Genemco is ready to help.
Because sometimes the most valuable piece of equipment isn't the newest one—it's the one that keeps your production line running when every minute counts.
