Self-Cleaning Filter Eradicates Downtime for Sausage Co-Packer

Chances are the pork sausage on the breakfast plate came residence within the food market frozen-food items area. If it’s among the list of huge-identify models, chances are equally superior that it was not processed by the company whose identify is about the deal but by a co-packer – a company that makes a speciality of that particular merchandise.
One of several more substantial co-packers within the Midwest provides lots of frozen pork sausage everyday inside a steady procedure that features blending the meat and spices, stuffing the casings or forming the patties, cooking the sausages, and finally freezing the ready-to-consume products. That remaining significant move is completed in a complicated waterfall pouch chiller using a food stuff-quality propylene glycol/h2o combination at -5° F (-21° C).
Because the glycol/water mixture can arrive into Bodily connection with the product, and because very little is perfect – which include packaging – the chiller is equipped with bottom-mounted screens to capture any bits of sausage or packaging components which could get into your liquid and keep them outside of the warmth exchangers. This functionality is critical to the method because the glycol/drinking water mixture needs to be preserved in just a slim temperature vary to meet demanding food items-protection regulations.
Should the screens turn out to be clogged, the movement of glycol/drinking water with the heat exchangers is diminished, along with the temperature in the processing place rises. In the event the temperature exceeds foods-basic safety recommendations, then the whole batch of sausage and the potentially contaminated glycol/water mixture would need to be discarded or “reworked” if problems was minimal.
“That happened two or thrice a year on ordinary,” said Jeff Simpson, a fluid system and industrial wastewater engineer at Crane Engineering in Kimberly, Wisconsin. “The price of replacing the process fluid on your own was about $twenty,000 for every incident.
In addition, routine maintenance costs ended up jogging from the $forty,000 to $sixty,000 range a year, and so they still weren’t preventing the over-temperature incidents.
The client was walking a high-quality line in between the cost of labor and downtime to wash the screens and sumps, and the price of dropped output although the chiller was out of Procedure getting cleaned.
Whilst the specific situation Obviously referred to as for any simpler filtration technique, managing the one,000 GPM
(227 m³/h) movement of glycol/drinking water throughout the program offered an strange challenge. That challenge was made even more difficult by The client’s ask for for an answer that didn’t call for the method being shut down for filter routine maintenance.Check Head Protection equipments here
The conventional alternate options ended up both a multifilter system with sufficient added potential to take care of the flow while one of the filters was offline for routine maintenance or possibly a self-cleansing filter that didn’t require downtime for upkeep. Whilst the self-cleaning filter supplied important Value Added benefits, the amount of glycol/drinking water that had to be filtered was better compared to capability of then-available standard versions.

We decided to go after the self-cleaning substitute,” Simpson claimed, “and to verify the thought we mounted an Eaton DCF-800 self-cleansing filter over a facet stream. That exact filter is rated for sixty GPM (13.five m³/h), As well as in various months of Procedure at most circulation it under no circumstances clogged or expected any servicing.”
The DCF filter is made of a cylindrical stainless-steel housing that holds a filter aspect. Fluid enters In the component and flows as a result of it for the outlet, depositing any contaminants on The within wall in the element.
A spring-loaded cleaning disc moves up and down, wiping the filter element clean and depositing the contaminants at The underside of the housing, out of the stream route. This prevents a resuspension. Normal cleansing frequency could be depending on time, differential pressure, handbook choice, or every other application-certain requirements. Because it remains in provider although remaining cleaned, the DCF filter pleased The shopper’s no-servicing-downtime prerequisite.
“While using the thought demonstrated, another hurdle was locating a self-cleaning filter with enough ability to take care of the complete 1,000 GPM (227 m³/h) circulation of glycol/h2o inside the process,” Simpson stated. “Through our contacts with Eaton, we understood they were engaged on a bigger Model of your DCF series, and this application was an excellent fit for that device.”
Crane was in a position to obtain one of the 1st of the new Eaton DCF-3000 filters developed and put in it while in the co-packer’s chiller circuit. All components in contact with the merchandise are created of stainless-steel and the filter is rated at 1,100 GPM (250 m³/h) while filtering up to one hundred microns. It stands 8 ft (2.forty meters) tall and weighs around 720 lbs (325 kilograms) when absolutely flooded. It could be equipped with slotted wire strainer components ranging from fifty to one,140 microns to satisfy a wide array of software requirements.
