5 Elements to consider when cleaning your tank

5 Elements to consider when cleaning your tank


Employee safety should always come first and although the traditional method of cleaning tanks is done by hand, it can be very dangerous.  Today, tank cleaning nozzles have become very popular for cleaning tanks and for a good reason!  These devices can be mounted inside the tank where the process in now automated so that employees no longer have to climb inside tanks with a pressure washer and clean.  This avoids the risk of anyone falling and injuring themselves while inside the tank.  Tank cleaning nozzles require less time for cleaning and use less water and chemicals in the process.  More importantly, you can be assured that your cleaning results are accurate every time! 

2. Choosing the right nozzle

Static vs. Rotational

Should I go with a nozzle that is static or one that rotates? Static spray balls are typically installed by tank manufacturers and although they are economical; they are only good for light rinsing.  Static spray balls deliver a solid stream of spray and do not provide full coverage for cleaning.  Rotating nozzles, on the other hand, spray the entire surface of the tank and provide more penetration for removing stubborn soils.  There are three different types of rotational spray nozzles: Free spinning - This cleaning device is driven by the pressure of the water. The head of the nozzle rotates faster as the pressure increases.  These nozzles clean best at low pressures of 40 to 60 psi and are perfect for small to medium size tanks.

Below is an example of one of our free spinning nozzles removing chocolate sauce.

Controlled rotation – The rotation of this nozzle is controlled by an internal turbine and it contains no gears.  The slower rotation provides more impact and better spray coverage for removing very difficult soils like tannins and titrates.  These nozzles can also be run at higher pressures, which will not affect the speed of the rotation.

Below is an example of one of our controlled rotation nozzles removing chocolate sauce.

Gear-controlled – These types of nozzles provide the highest impact and are excellent for cleaning large fermentation and storage tanks.  The nozzle rotates on two axis points, which allows it to sweep the entire 360° circumference of the tank interior.  This assures every spot will be cleaned.

3. Chemicals, time and temperature - Less is more!

Chemicals, time and temperature all cost money, so the less you need and use will save you more money in the long run.  Choosing the correct nozzle for your cleaning process, will have a positive effect on all 3 of these.  The right temperature and chemicals being used with the nozzle will help reduce your cleaning cycle, which means less chemicals and downtime.  Not only does this save you money but now you can produce more wine.

4. Tank Obstructions

Debris can collect around and under agitators & baffles, if the residue is light to moderate the run off from the nozzle may be able to clean it. However, if your residue is thicker you may need to insert another nozzle within that area to clean it effectively.

5. Nozzle Placement

Installation and placement of your nozzle is critical for your cleaning process.  For nozzles mounted at the top of the tank, the rule of thumb is they should be placed 1/3 down from the overall height of the tank. For tanks with side or bottom entry ways, Lechler offers a cart which attaches to the nozzle.  The nozzle and cart are inserted into the center of the tank for quick and proper cleaning.
