  • Internal Keg Washing

    1. Clean kegs are critical to the quality of draft beer.

    2. CIP processes similar to that used in cellar tank cleaning are normally used, but

    at elevated temperature.

    3. If not cleaned properly, beerstone/tannin deposits can develop inside kegs.

    This is especially true for kegs holding unfiltered beer, where yeast deposits

    can add to these issues. Beer-spoilers can hide underneath these layers.

  • Pre Rinsing & CO2 Exhaust

    Most critical step why?

    Option Expected goal Comment

    Water flush Removing gross soil Good and consider using reclaimed water to reduce water cost.

    Air blowing Blow out the CO2 This step is critical and need to be optimized as much as possible

    Sacrificial Caustic Pre-clean the keg and removing CO2 Very little benefit observed for CO2 reduction.

    Acid Rinsing Removing gross soil Very good practice especially if followed by a caustic wash without rinsing (over ride)

    Water filling Removing CO2 Very effective for CO2 removal but very high usage of water and time

    Conductivity does not indicate a problem

    Titration shows rapid loss of active alkalinity, and a rapid buildup of carbonate alkalinity

    Sodium Bicarbonate (not showed in graphic) will foamed and will make the cleaning solution hard to rinse

    Optimizing the CO2 blowout step will help to achieved sustainability of the cleaning performance and lowered your chemical cost.

    VorfhrenderPrsentationsnotizenIf you expand this view to a full day of cleaning and filling returned barrel kegs, we see the same trend in the morning of rapid hydroxide alkalinity degradation paired with an equally rapid accumulation of carbonate alkalinity. We also see that throughout the day, active alkalinity never recovers and by the end of the day we had no active hydroxide alkalinity in the wash solution.Now let me point out something very interesting here. This green line that hovers around 77 80 mS, as shown on the secondary y-axis on the right, represents the conductivity reading of the caustic wash solution throughout the day. You can see that it starts off high in the morning, and as active alkalinity is consumed, conductivity drops. At the point where carbonate alkalinity becomes the dominate species in the wash solution, the conductivity has reached the set point, and continues to maintain its set-point throughout the day by cyclically re-dosing every 7 10 kegs. Whats happening here is that the carbonate ion is also a very conductive ion. As hydroxide alkalinity is consumed, the conductivity lost is being replaced by the conductive carbonate ion. The conductivity meter can not differentiate between the two species, and only reads the conductivity of the entire wash solution.So, the key learning here is that conductivity does not tell the whole story. According to conductivity, weve maintained the set-point all day long and everything should be fine, but the titration results show a loss of active alkalinity, replaced with carbonate alkalinity! The next question is, why is this happening? Could it be reaction with excess CO2 coming in with the returned kegs?
  • Cleaning

    Most critical step why?

    Option Advantage Desavantage

    Caustic Best in class cleaning agent for beer soils residue

    CO2 residual in the kegs will reduce the effectiveness of the cleaning.

    If the additive in the blend do not controlled the mineral precipitation, scale and beer stone or foam will appear.

    Acid

    CO2 will not reduce the product performance.

    Prevent scaling and controlling beer stone.

    Good to moderate cleaning agent for organic soils. On a long time usage a combination of organic soils an

    Calcium Oxalate can appear.

    Caustic and Acid

    Providing all the advantage from both products and usually controlling soiled buildup.

    Need a more intensive equipment investement to performed both wash.

    Combine Premium Caustic

    Providing the same advantage of a Caustic / Acid cleaning in a single step wash.

    Can be used on a one step wash machine.

    Higher cost of Caustic product.

  • What is CIP Clean-in-Place

    The cleaning of a beer pipeline. filling machine or vessel with minimal disassembling of equipment components (hence the name Cleaning in Place)

    The process involves the jetting or spraying of solution through spray devices on a tank or vessel surface or by the controlled flow velocity through pipelines

    Preparation - Critical Disassemble, clean all surfaces NOT cleaned by CIP Brush wash dead areas

    Mechanical Force is the most common challenge

    Remove gross soils from surface

    Soil being lifted from surface and held, suspended or dissolved within the detergent solution

    Helps assure Food Safety

    Mechanical Force is the most common CIP challenge for keg filler and beer line circuits Different pipe sizes.

    Same flow but different velocity Dead legs

    Difficult or impossible to clean by CIP(micro harborage) Manual cleaning

    Split flows The flow will be split by pressure and not by pipe size or velocity (difficult to

    impossible to control) Equipment (Cooler, Flash pasteurizer, Holding tank)

    Equipment is engineered with a recommended flow / pressure. Verify the head loss pressure

    Long circuits Increases the head loss pressure and makes the CIP pump ineffective (pump

    curve)

    NO SPRAY DEVICE IS BAD. ITS ONLY INADEQUATE FOR THE JOB Spray Ball

    Properly sized spray ball will achieving tank cleaning in the shortness time and energy with a lower maintenance cost

    Operate to a lower pressure (25 PSI) 1 axle Rotary Spray

    Will required less water but will need longer step time With the exception of a visual inspection its impossible to

    validate to rotation. Multi axal Rotary Spray

    Usually required a higher pressure at the pump to operate Rotation can be monitor Longer time due to pattern. High maintenance
