Saving Water in the CIP Process in the Brewing Industry A Comparison of Technologies Available Mark Murphy Global Industrial Sales Manager Butterworth, Inc.

What is CIP? • Clean-in-Place (CIP) is a method of cleaning the interior surfaces of pipes, vessels, process equipment, filters and associated fittings, without disassembly. • Depending on soil load and process geometry, the CIP design principle is one of the following: – deliver highly turbulent, high flow-rate solution to effect good cleaning (applies to pipe circuits and some filled equipment). – deliver solution as a low-energy spray to fully wet the surface (applies to lightly soiled vessels where a static sprayball may be used). – deliver a high energy impinging spray (applies to highly soiled or large diameter vessels where a dynamic spray device may be used). • Elevated temperature and chemical detergents are often employed to enhance cleaning effectiveness.

What Factors Effect a Good CIP? • Soil in the Vessel – Fat based soils – Protein based soils – Carbohydrate based soils – Mineral based soils • Environmental Factors – How clean is your surrounding environment? – Surface outside of the vessel? – Air conditioning / filtration system? – Ambient temperature of process area? – Nearby processes?

What Factors Effect a Good CIP? Continued • Good Piping Practices – Dead legs – Surface conditions – Materials • Good CIP Practices – Temperature Control – Cleaning Action – Chemical Control – GASKETS, LIDS and CAPS!!!!

What is Impingement? • Impingement is best described in a decontamination setting as the mechanical action of pressurized water forced through spray jets to remove debris. High impingement is achieved by means of forced water through water channels which are then directed to spray arm jets by utilizing highpressure water pumps. The relative efficiency of a washer mechanical impingement action is between 50 percent to 60 percent of forced water delivered by the spray arm’s jets. Impingement is not necessarily dependant on the volume of water, but the delivery of said water to the object being cleaned with force. • From home dishwashers to car washes, high impingement is employed in many ways by means of water, chemicals, solid material and air.

Real World Application • • • Customer estimated a savings of 2, 000 gallons per CIP. Water costs of $1. 92 per 750 gallons. Sewage costs of $0. 93 per 750 gallons. Electrical savings from not running a 10 Hp CIP pump for ½ hour per CIP at 0. 00259 Kwh. Water savings = $5. 12 Sewage savings = $2. 48 Electrical savings = $37. 23 Total savings per CIP = $44. 83 Now consider a fermentor is cleaned on average every 10 days, this is 36. 5 X $44. 83 = $1, 636. 30 per fermentor per year. • Insert the number of fermentors you have here X $1, 636. 30 = ?

Summary and Conclusions • Is it time to review the devices / methods used in your brewery for an update to save water, chemicals and time? • In almost every audit, small, inexpensive items are found that can have a significant impact on your bottom line. • Please consult your CIP equipment manufacturer AND your chemical supplier, both may have some very good ideas. In most cases, the audits are at little or no cost.
