DAIRY INDUSTRY SELF CLEANING FILTERS
Our Spiroclean Filters are designed specifically for use in dairy applications, as they are built to sanitary design standards.
Hygienic
-
Spiroclean filters are designed in accordance with EHEDG (European Hygienic Engineering Design Group) hygienic design standards
-
All internal and external elements in contact with fluid are MOCA certified (European Regulation 1935/2004 for materials intended to come into contact with food)
Self Cleaning
-
The self cleaning feature means that plant operators do not need to carry out manual cleaning or change filter bags
-
There is no production downtime, production continues during the filter cleaning step
Modular
-
A range of flow capacities to suit any process.
-
Our self cleaning filters are often used to replace existing bag filters or screen filters, to reduce the need to periodically open and clean these existing filters.
-
Easily integrated into existing or new plant, with a small footprint.
Applications
Removal of particulate matter from liquid processing flows
This filter removes suspended solids from a liquid flow that are greater than the filtration grade/size. The resultant product has suspended solids removed, with a discharge of the solids portion to waste.
Pre-filtration before whey ultrafiltration
Removing larger particles before whey ultrafiltration results in greater flux rates and longer run times. Using a self cleaning filter means that this pre-filtration step can be carried out in line, and without imposing any stoppages on the feed flow for filter cleaning.
CIP solution re-use
CIP solution can pick up significant levels of TSS during a cleaning cycle. These can be removed by a self cleaning filter, allowing for subsequent re-use of the caustic solution. There is significant savings achieved through CIP re-use (chemicals, heat, CIP disposal costs, etc.).
Cheese Brine Filtration
Removal of the contaminants that build up in cheese brine will extend the useful life of the brine. Our self cleaning filters are often used in a 'kidney system' arrangement , filtering a portion of the brine. The microbial load will be reduced, and the consistency of the brine improved. A self cleaning filter followed by ultrafiltration is an even more complete treatment.
Upgrade of existing bag or cartridge filters
Where existing filters are in place, upgrading to a self cleaning filter has the advantage of not needing plant operators to change filter bags or cartridges. There is a safety aspect in some cases, self cleaning filters eliminating the risk when the product is hot or a chemical. Self cleaning filters require no process downtime for filter changes.
Technical Details
Mode of operation:
The feed flow enters a cylindrical filtration chamber, where particulate matter is deposited on the surface of the filter media.
Rotating scrapers remove the particulates, transferring them to a discharge chamber.
The self cleaning and discharge mechanism is automated, therefore not adding to the workload of plant operators
The Spiroclean filter is a compact unit, and is an easy addition in line to existing plant.
Flowrates
Up to 100 m3/hr with a single filter. Higher flowrates use multiple filters in parallel.
Degree of filtration
From 50 microns up to 2000 microns
Filter media
AISI316 stainless steel
Smaller apertures are laser micro-perforated
Filtration area
Spiroclean 20: 2000 cm2
Spiroclean 30: 3000 cm2
Spiroclean 45: 4500 cm2
Spiroclean 60: 6000 cm2
