Bottle washing-foam (1) bottle washing machine
Foam is the enemy of effective bottle washing.
Foam is the number one enemy of bottle washing machine to wash bottles effectively.
foam
The pump pumps out air together with NaOH solution, and the bottle will not be cleaned internally.
The fluctuating pressure gauge shows the presence of air.
If the pumped lye is mixed with air, the inside of the bottle will not be thoroughly cleaned.
The fluctuation of the pressure pointer of the pressure gauge indicates that this has happened.
Excessive foam in the label extractor will bring NaOH out with the foam.
Resulting in high NaOH dosage and pollution.
The more foam the trademark extractor emits.
This will lead to an increase in lye consumption and environmental pollution.
The more lye is brought out.
Foam will increase the liquid on the bottle and carrier into the next compartment.
Contaminate the final rinse section with NaOH.
Foam will increase the amount of liquid in the bottle.
Finally, the phenomenon that the spray water after cleaning is polluted by alkali liquor appears.
And take the bottle into the next tank farm.

Foam is the number one enemy of bottle washing machine to wash bottles effectively.
foam
Foam will cause the label paper to break because there will be a delay in taking out the label from the washing machine.
The pulp label will block the filter screen and nozzle of the washing machine
When the trademark stays in the bottle washer for too long,
Foam will break the label paper.
Standard mud will block the filter screen and nozzle of the bottle washer.
The label will stay on top of the foam in the compartment and will not sink to allow the label extractor.
Tear the label off the washing machine.
The trademark will remain on top of the foam layer in each tank area.
Instead of sinking to the bottom, it was removed by the trademark extractor of the bottle washing machine.

Possible causes of foam formation:
Possible causes of foam formation
Clogged pump filters and/or clogged nozzles (high pump pressure) can produce foam.
Blocked pump screens and/or nozzles (too high pump pressure) will produce foam.
The leaked heat exchanger or steam condensate enters the main soaking chamber through the pipeline.
Heat exchanger leaks or steam condensate enters the main storage tank area.
When NaOH solution is & lt50±0°C, foam will be produced during preheating.
When the alkali liquor temperature is lower than 50 degrees.
Foam will be produced during heating.

Bottle washing scale
The problem of scale formation:
Scaling problem:
odd jobs
-Zoom
Scale will increase the amount of NaOH, because NaOH solution will stick to the bottle rack and bag.
Take it to the next tank.
Because lye will be left in the bottle barrel and bottle rack.
Move to the next tank farm, so the scaling phenomenon in the bottle barrel and the bottle truck will increase.
Alkali consumption
It will cycle.
Scale will promote the growth of bacteria in warm water and may lead to
The sour taste of bottled beer.
Scale will promote the growth of bacteria in warm water areas.
And may cause the sour taste of wine tasting.
Scale blocks the pump and nozzle.
Scaling will block the pump and nozzle.
The descaling of warm water parts and pumps is expensive and time-consuming, and there are potential safety hazards.
And damage the equipment.
The cost of descaling warm water area and water pump is very high.
Safety and easy to damage equipment and other hidden dangers.
And it takes a lot of time.
