A small difference in texture, consistency, or temperature can make a big difference in how a product performs.
For consumers, the experience may seem simple—a lotion that spreads smoothly, a cream that absorbs evenly, or a toothpaste that dispenses with the right consistency. But behind these everyday products is a highly controlled manufacturing process where temperature, viscosity, and product stability must be carefully managed.
In the pharmaceutical and personal care industries, consistency is more than a quality goal—it is a requirement.
Many pharmaceutical and cosmetic products contain ingredients that are sensitive to temperature changes, require precise cooling profiles, or become increasingly difficult to process as viscosity increases. This is why manufacturers often rely on Votators®, also known as scraped surface heat exchangers (SSHEs), to help achieve the control and reliability their products demand.
Designed for thick, sticky, and temperature-sensitive materials, scraped surface heat exchangers provide a level of processing control that traditional heat exchangers may not be able to deliver.

Why Temperature Control Is Critical in Pharmaceutical & Personal Care Manufacturing
Manufacturing a pharmaceutical cream or a cosmetic lotion is not simply a matter of mixing ingredients together.
Many formulations require specific heating and cooling steps to:
- Maintain ingredient stability
- Achieve the desired viscosity
- Prevent separation
- Encourage proper crystallization
- Protect sensitive compounds
- Create a consistent finished product
A product that is overheated may lose important characteristics.
A product that cools too quickly may develop the wrong texture.
A product that experiences uneven temperature changes may separate or become inconsistent from batch to batch.
For manufacturers producing thousands of units per day, even small variations can lead to production challenges, quality concerns, and increased waste.
How Scraped Surface Heat Exchangers Work
A scraped surface heat exchanger is designed differently than a traditional heat exchanger.
Inside the unit, rotating scraper blades continuously move along the heat transfer surface. As product passes through the equipment, the blades gently remove material from the surface while maintaining constant movement and mixing.
This provides several advantages:
- Prevents product buildup on heat transfer surfaces
- Improves heat transfer efficiency
- Creates more uniform temperatures
- Helps process highly viscous products
- Reduces the risk of scorching or degradation
For pharmaceutical and personal care manufacturers, this gentle but consistent processing approach helps maintain the characteristics that make each formulation unique.
Common Pharmaceutical & Personal Care Applications
Many pharmaceutical and cosmetic products require extremely controlled heating and cooling throughout production.
Common applications for scraped surface heat exchangers include:
- Ointments
- Creams
- Lotions
- Gels
- Waxes
- Toothpaste
- Medical creams
Although these products serve different purposes, many share similar manufacturing challenges. They are often thick, temperature-sensitive, and dependent on precise consistency.
Ointments & Medical Creams
Pharmaceutical ointments and medical creams require exceptional consistency because they are designed for specific applications where dosage and coverage matter.
Temperature control during processing helps ensure:
- Uniform ingredient distribution
- Proper texture
- Consistent application characteristics
- Product stability
Scraped surface heat exchangers help manufacturers maintain controlled processing conditions while handling formulations that can be difficult to move through conventional equipment.
Lotions & Cosmetic Creams
Consumers expect lotions and creams to feel smooth, absorb evenly, and maintain the same quality every time they purchase them.
Behind that experience is careful control of:
- Viscosity
- Cooling rates
- Ingredient blending
- Emulsion stability
Scraped surface heat exchangers help prevent product separation while maintaining the smooth, consistent texture customers expect from personal care products.
Gels & Specialty Formulations
Gels are often highly viscous and can be challenging to heat or cool uniformly.
Whether used in personal care products, medical applications, or specialty formulations, gels require careful handling to maintain their structure and performance.
Scraped surface heat exchangers help manufacturers process these products while reducing the risk of uneven temperatures or unwanted changes in viscosity.
Waxes & Temperature-Sensitive Products
Many wax-based products rely on precise temperature management to achieve the right melting, cooling, and crystallization characteristics.
Improper cooling can affect hardness, appearance, and performance.
By providing consistent heat transfer and continuous product movement, scraped surface heat exchangers help manufacturers create repeatable results.
Toothpaste Manufacturing
Toothpaste is a perfect example of a product that appears simple but requires sophisticated processing.
Its thick consistency, abrasive ingredients, and strict texture requirements make temperature control and mixing essential.
Scraped surface heat exchangers assist manufacturers in maintaining uniform processing conditions and producing toothpaste with the smooth texture consumers expect.
The Advantage of Gentle, Consistent Processing
In pharmaceutical and personal care manufacturing, quality cannot be separated from consistency.
A scraped surface heat exchanger can help provide:
- Precise temperature control
- Improved product uniformity
- Reduced fouling and buildup
- Better handling of high-viscosity formulations
- Improved process reliability
- Reduced production interruptions
- Longer operating cycles between cleanings
For manufacturers producing sensitive formulations, the ability to repeat the same process successfully every time is invaluable.
When Manufacturing Timelines Meet Production Reality
Even the most carefully planned manufacturing operation can face unexpected challenges.
Equipment eventually requires replacement.
Production demands increase.
A critical component may fail at the worst possible time.
And when specialized processing equipment is needed, new equipment lead times can sometimes extend far beyond what production schedules can tolerate.
The reality is simple: customers still need products, orders still need to ship, and production teams still need solutions.
In those moments, having access to quality pre-owned equipment can provide an important bridge while a permanent solution is being built.

Helping OEMs Become the Solution Their Customers Need
At Genemco, we understand the importance of OEM relationships.
When you've earned a customer's trust and sold them a new scraped surface heat exchanger, we don't want to take that sale from you.
Your new equipment project is important.
Our goal is to support it—not compete with it.
If your customer is facing a long lead time before their new equipment arrives, Genemco can help provide a temporary solution to keep their operation running in the meantime.
Think of it as a short-term lifeline.
A bridge between today's production challenge and tomorrow's permanent installation.
A quality pre-owned scraped surface heat exchanger can help your customer avoid unnecessary downtime while protecting the new equipment purchase you've worked hard to secure.
Instead of your customer hearing, "You'll have to wait several months," they hear, "We have a plan."
And that's where you become the hero.
Because great partnerships aren't just built when everything goes according to plan—they're built when challenges happen and someone steps up with a solution.
