Whether it's the silky center of a sandwich cookie, the glossy glaze on a donut, or the rich chocolate coating on a candy bar, consumers notice when bakery and confectionery products are just right. They also notice when they're not.
A filling that's too thick won't deposit correctly. A glaze that's too thin won't coat evenly. Chocolate that isn't cooled properly can lose its shine, and fondant that isn't processed consistently can become grainy or difficult to work with.
For bakery and confectionery manufacturers, consistency isn't just about appearance—it's about protecting product quality, reducing waste, and keeping production lines operating efficiently.
That's one reason Votators®, or scraped surface heat exchangers (SSHEs), have become indispensable pieces of equipment throughout the industry. They're specifically designed to process products that are too viscous, sticky, or temperature-sensitive for conventional heat exchangers, helping manufacturers achieve the smooth textures and precise temperature control today's production demands require.

When Texture Sells the Product
Walk through the bakery aisle or candy section of any grocery store, and you'll find products competing for attention based on how they look and how they feel.
Consumers expect:
- A donut glaze that's glossy and smooth.
- A chocolate filling that's creamy and rich.
- A cookie center that's soft and consistent.
- An icing that spreads evenly every time.
Those qualities don't happen by accident.
Many bakery ingredients change dramatically with even slight temperature variations. Sugars crystallize, fats solidify, chocolate becomes unstable, and creams can separate if they're not handled carefully throughout production.
Maintaining those ideal conditions requires equipment capable of delivering precise, consistent heat transfer without damaging the product.
Why Conventional Heat Exchangers Aren't Always Enough
Traditional heat exchangers perform exceptionally well with low-viscosity liquids that flow easily.
Bakery and confectionery products are different.
Many formulations are thick, sticky, sugar-rich, or contain fats that become increasingly difficult to process as temperatures change.
As product clings to the heat transfer surface, several problems can occur:
- Ingredients begin to scorch.
- Sugars caramelize unevenly.
- Product temperatures become inconsistent.
- Heat transfer efficiency decreases.
- Production slows for cleaning and maintenance.
Scraped surface heat exchangers overcome these challenges by using rotating scraper blades that continuously remove product from the heat transfer surface while gently mixing it throughout the process.
Instead of allowing product to remain in one place long enough to burn or stick, fresh product is constantly moving through the system.
The result is more efficient processing and more consistent finished products.
Bakery & Confectionery Products That Benefit from Scraped Surface Heat Exchangers
Throughout the bakery and confectionery industry, scraped surface heat exchangers help process a wide range of products, including:
- Icings
- Fillings
- Fondant
- Chocolate compounds
- Cookie fillings
- Donut glazes
- Cream fillings
These products often require careful heating, cooling, or crystallization to achieve the desired consistency before they are deposited, coated, or packaged.
For example:
A chocolate compound must cool uniformly to maintain a smooth texture and attractive appearance.
A cream filling needs consistent viscosity to ensure every pastry receives the same amount during depositing.
A donut glaze must remain fluid enough to coat evenly while setting quickly once applied.
Even small variations can affect production efficiency, finished product quality, and customer satisfaction.
Precision That Extends Beyond Temperature
One of the biggest advantages of scraped surface heat exchangers is that they don't simply heat or cool product—they help maintain product integrity throughout processing.
By continuously scraping the heat transfer surface, manufacturers benefit from:
- Uniform product consistency
- Improved heat transfer efficiency
- Reduced fouling and buildup
- Gentle handling of delicate formulations
- Better control of crystallization
- Longer production runs between cleaning cycles
- More consistent depositing and filling performance
For operations producing thousands of cookies, pastries, cakes, donuts, or confectionery items every hour, that consistency translates directly into reduced waste and improved productivity.
Production Deadlines Don't Wait for New Equipment
Bakery and confectionery production is often driven by tight schedules, seasonal demand, and retailer delivery commitments.
If a scraped surface heat exchanger unexpectedly goes offline, production can't simply pause for several months while waiting for replacement equipment.
Orders still need to ship.
Ingredients continue arriving.
Customers still expect full shelves.
When lead times for new equipment stretch longer than production schedules allow, processors need practical options that keep operations moving without compromising quality.
Helping OEMs Strengthen Customer Relationships
At Genemco, we view OEMs as partners—not competitors.
If you've sold a customer a brand-new scraped surface heat exchanger, that's exactly how it should be. Our role isn't to replace that purchase.
Instead, we help fill the gap when manufacturing lead times create operational challenges.
If your customer's new equipment won't arrive for several months, Genemco can often provide a quality pre-owned unit that keeps production running until installation day.
Think of it as temporary support during a critical period.
Just as a temporary oven can keep a bakery operating after an unexpected breakdown, a pre-owned Votator or scraped surface heat exchanger can help your customer maintain production while waiting for their permanent solution.
Your customer continues meeting production goals.
Your equipment sale stays in place.
And you become the trusted partner who delivered an answer instead of asking your customer to simply wait.
Sometimes the strongest customer relationships are built during the moments when challenges arise—and we're proud to help OEMs turn those moments into opportunities to exceed expectations.
