An Introduction to CIP & RML Retractable CIP Nozzles

Written by Jo on May 2nd, 2017.      0 comments

What is CIP?
CIP is “Clean In Place”. It is the process used for the hygienic cleaning of equipment using an automated system, without theRML Engineering CIP Nozzle Blog-174 need for disassembly of parts.
The automated system is used to deliver water and a range of cleaning fluids to CIP Nozzles mounted throughout the equipment. There are several aspects to the CIP process including:
  • Duration
  • Fluid flow rate
  • Fluid pressure
  • Fluid temperature
  • Fluid type / Chemical composition


What advantages does CIP have over alternative methods?


The alternative methods to CIP are COP (Clean Out of Place) and Manual Cleaning.


COP involves the disassembly and removal of the equipment to be taken to a designated cleaning area for a combination of manual cleaning and immersion cleaning.


Manual Cleaning involves training cleaning staff and conducting an assessment on completion.


Both COP and Manual Cleaning methods are labor intensive and time consuming. They introduce additional Health & Safety risks due to a high level of staff involvement. Additionally, manual cleaning methods can have varying results, which may lead to re-cleaning and further lost time.


The advantages that CIP has over the other methods are:


  • Time efficient
  • Very low staff involvement
  • More control over the above listed CIP process aspects
  • Reliability and Repeatability

Creative Finance Solutions

One way that RML are developing, is by offering innovative financing solutions that provide:

  • Off-balance sheet funding    RML-c402-Two-Flap-Sealer
  • Tax effectiveness
  • Improved timeliness of solutions and benefits
  • Entry to machines that would otherwise be capital prohibitive                                    
  • Avoid locking in to solutions that might be quickly outgrown
  • Full service provision during the lease term

We are keen to discuss how we might find ways to assist with funding. We often see projects with impressive paybacks that stall because of capital constraints. A lease machine could deliver real benefits in a matter of months.

Bottom Load Case Packer Delivers Labour Savings For Pampas

Written by Jo on October 10th, 2016.      0 comments

Popular baking brand Pampas has recently taken delivery of an Blog Post 1 Image-7automated pastry packing line from RML for its Melbourne plant.
The solution, aimed at reducing repetitive manual packing tasks, delivered on promised labour reduction by converting manual case erecting and packing tasks to a fully automated line.  The bottom load case packer was specifically configured for the range of pastry products which included both flow wrapped and cartoned products.
As the product rate was significant, a bottom load packing approach was adopted which in this instance was faster than the equivalent top load solution.
The customer also has peace of mind with machine servicing provided by our Australian support team.
