Tank cleaning equipment

Regular tank cleaning is critical to product integrity, productivity and profitability for food, dairy and beverage producers.

What is tank cleaning

Tank cleaning refers to the thorough cleaning of the tank after each batch to prevent contamination and microbiological spoilage. For that the cleaning machines need to generate geometric reach of all interior surfaces (coverage) and sufficient impact force on the surfaces. The tank cleaning machines use a combination of mechanical cleaning (impact force), chemical cleaning action (caustic, acid, disinfectant), time and temperature.

Why is tank cleaning important

Your tank must be thoroughly cleaned after each batch to prevent contamination. That is why it is one of the most important operations to get right.

It is important to ensure that the tank cleaning machine itself is cleaned. Its hygienic self-cleaning construction ensures that the cleaning fluid reaches the external surfaces of the rotary jet head this reduces the risk of cross-contamination as well as the potential risk of product loss or product recalls.

What are tank cleaning machines

Different types of spray heads are used for tank cleaning. When tank cleaning machines are in place, it’s often hard to imagine making a switch.

Although the static spray ball is the most widely used permanently installed tank cleaning device, there are measurable benefits to upgrading to dynamic tank cleaning, especially when the risk of contamination is high and hygiene is a critical factor.

The dynamic movement and high impact force of the jets cut the costs associated with water, acid, caustic and disinfection by up to 70% and cleaning time by 50%.

  1. The Alfa Laval Static Spray Ball is the cleaning method of choice for low impact cleaning of water-soluble products. Cleaning requires long cycle times and large volumes of cleaning fluids and subsequently large volumes of wastewater.
  2. The Alfa Laval Rotary Spray Head uses the rotary motion and physical impact of the cleaning media to remove sticky residues from the tank interior.
  3. The Alfa Laval Rotary Jet Head provides a high-impact jet stream in a three-dimensional cleaning pattern to clean tough residues. The result is a thoroughly clean tank using a fraction of the time, energy, water and cleaning chemicals required for other tank cleaning solutions.

What is cleaning in place and how does it work

Cleaning in Place (CIP) enables cleaning of tanks without dismantling, manual cleaning processes, or man entry.

CIP typically consists of tank cleaning machines installed inside the tanks. The tank cleaning process involves cleaning stages using water and chemicals that circulate through the CIP system to the equipment for thorough cleaning and disinfection.

The CIP equipment proceeds through the entire sequence of cleaning steps without requiring human intervention. Irregularities such as a drop or increase in CIP supply pressure or cleaning nozzle blockage can be monitored through a sensor such as the Alfa Laval Rotacheck.

Pro Tip: Burst cleaning

Burst cleaning means applying the caustic directly to the tank without wetting first. Some or all of the caustic go to the drain (sacrificial caustic) however it is used in small amounts. When the caustic is running clear, the tank is clean and solids have been removed. This method reduces cleaning time and with that production downtime significantly.

How to optimize Cleaning in Place for water and energy savings

Most companies are looking for a reduction in energy use and water consumption but solutions are often costly and will actually increase the plant’s overall energy usage. Before looking at larger investments in wastewater treatment, optimizing essential CIP technologies is a proven way to increase profitability and sustainability in your processing plant.
