A gut washer installed by leading Australian wastewater treatment company, CST Wastewater Solutions at Thomas Foods International is helping the client achieve greater efficiency and cleaning results.
CST’s latest gut washer technology, which is broadly applicable to meat and agricultural industries across Australia, is configured to wash and then flush digested matter from cut paunch material, producing a better grade of tallow and added value for Thomas Foods of Murray Bridge, South Australia. A combination of mutton and beef is washed at a rate of approximately 10,600kg per hour from the abattoir’s daily processing.
Gut washing is a standard meat industry practice where 6-12mm trommel screens are commonly used to simply drain the cut gut with no consideration given to washing.
However, with the CST gut washer, the cut gut is fed via a transition chute to the rotary screen/gut washer consisting of an external entry swirl chamber with two off-set flanged recycled wash water inlets. The cut gut is then swirled with 10 times its volume of water.
On entry to the screen, this water is removed for further recycling before the solids are then sprayed via the product wash sparge arrangement with fresh water before final dewatering.
CST Wastewater Solutions’ gut washer utilises a 2.8mm wedgewire gap on the screen to optimise washing and flushing.
According to CST Wastewater Solutions Sales Manager, Mr Peter Bambridge, Thomas Foods International is very happy with the performance and efficiency of the unit. CST’s unit is made with guarding for safety and improves the downstream results, which is highly beneficial to Thomas Foods.
Mr Bambridge explains that that capture rate is much better, and the washing results in a cleaner, higher quality product leading to more easily sold by-products such as tallow and meat meal.
CST Wastewater Solutions has installed many screens throughout the meat industry with over 20 years of process and application knowledge.
