Chocolate Pump

" Keep the heat away! "

One of the main problems that confectionery manufacturers constantly face is temperature.

Pumping chocolate is a delicate process, and production can easily get clogged, literally.

Pumps that operate too fast or under excessive pressure can result in heating a product that is quite sensitive to temperature.

We can explain the challenges of working with chocolate as follows:

"Anyone who has ever tried making chocolate on a stove knows that overheating the chocolate results in caramelization or a coarse, flaky end product. This is not at all conducive to keeping the pumps spinning properly. In a chocolate factory, temperature is literally the enemy."

Different types of chocolate—dark, milk, white, and other blends—require different processing methods and have varying sensitivity to temperature due to their different sugar content. The higher the sugar content, the greater the sensitivity to temperature and the greater the likelihood of the pumps jamming.

Different types of chocolate (dark, milk, white) require different processing parameters due to their sugar content and thermal sensitivity.

  • Dark chocolate is relatively easier to pump because it contains less sugar.
  • White chocolate , being almost entirely composed of sugar and cocoa butter, is the most delicate type and must be processed at very slow speeds .

Therefore, a smooth, uninterrupted, and heat-free flow in the pump is a critical requirement.

Leakproof Design

Since chocolate is an expensive product, a leaking pump literally means siphoning off money. We can explain it like this...

"If a pump product is leaking, it's essentially like you're picking up snow from the ground and throwing it out."

Knife-Edge Hygienic Mechanical Seal ensures leak-free pumping of the product.

  • It keeps the temperature under control.
  • It prevents crystallization and stratification in the mill region.
  • Easy to clean.

Older pumps would leave controlled leaks in the shaft-neck area. Packo pumps with Lobe Knife Edge seals are designed to operate leak-free. If there is a leak, it means it's time for maintenance.

More Pressure, More Problems

Many confectionery manufacturers operate factories that have been in place for decades. In many cases, the production equipment may be almost antique, and the compatible infrastructure is in need of updating.

"Often, our customers want us to not only sell pumps but also provide consulting services regarding their applications. We typically advise them on how to install the pump to ensure the best reliability and performance."

The pumps recommended by Arpon improve production results in most setups, but the best performance comes from removing unwanted forces—such as pressure—from the pump. Ultimately, more pressure creates more friction. Friction generates heat. And heat is the enemy of chocolate production.

The world absolutely loves chocolate. Chocolate manufacturers keep their factories running 24/7 to meet demand, even during times of economic downturn. This means that it is extremely important for confectionery manufacturers not to experience interruptions. That's why the reliability of their pumps is so crucial for the world's largest producers.
