Our state-of-the-art manufacturing site is home to one of the most technically advanced extrusion facilities in the world.
Our investment in the world’s first thermal twin extruder allows GA to include extremely high levels of fresh meat in premium dry pet foods without the use of dry meat meals.
The improved palatability of a ‘Freshtrusion™’ diet is then further enhanced by the use of our new vacuum coater to evenly distribute fats, oils and palatants on and throughout each kibble.
With three extruders, GA has a production capacity of 100,000 tonnes of super premium pet food and the ability to make batches from 5 tonnes to 200 tonnes to suit all partner’s needs. GA delivers the same exceptional quality and consistency, no matter the batch size.
Innovation in action: The Wenger TT3630
The Wenger TT3630 Thermal Twin extruder is unlike any other twin-screw extruder in use today, in terms of design, capabilities and efficiency, it works in perfect harmony with the Wenger High-Intensity Pre-conditioner (HIP).
Ingredients are gently mixed in the HIP by two independently driven shafts, which allow steam to be ‘folded’ into the product. Angled steam injector ports in the extruder barrel orientated in the direction of material flow, along with a unique screw profile allow further steam to be mixed into the product.
This means TT3630 can utilize up to four times more thermal energy and a half to one-quarter of the mechanical energy than other twin-screw machines. The reduced mechanical energy ensures a much less aggressive cooking process when compared to more traditional high sheer cook conventional extruders. This helps to preserve the digestibility of proteins and survival of the natural vitamins and minerals within the food whilst still achieving over 90% cook.
This new patented process also means carbohydrates like potato or rice content can be processed without the stickiness previously encountered in other extruder designs. Starches may be fully cooked without damage to functional and organoleptic properties. The most exciting prospect, however, is the ability to produce dry foods and treats with up to 70 per cent fresh meat.
The cooking process is completed with a unique 2 stage pre drier and secondary drying, which enables us to remove the high levels of moisture present in High Fresh Meat Kibbles and a vacuum coating system, which delivers unparalleled consistency when applying fats and oils post extrusion.
All this means that GA has the most advanced production facility in the world for the production of Super Premium dry pet foods.
How does it work?
Ingredients are gently mixed in the High-Intensity Pre-Conditioner by two independently driven shafts, which allows steam to be ‘folded’ into the product.
Angled steam ports in the extruder barrel orientated in the direction of the material flow, along with a unique screw profile allow further steam to be mixed in.
Using 4x more thermal energy and half to one-quarter of the mechanical energy of other twin-screw machines, a much less aggressive cooking process preserves the digestibility of proteins.
We can independently control the temperature of each section, allowing us to perfect the bespoke cooking process of our recipes.
Packing at GA
At GA, we continue to invest in our packing teams and automated machinery. We are proud of our multi-cultural, talented, experienced and committed teams and we are also excited by our state-of-the-art machinery. We work tirelessly to improve our processes to benefit our valued partner brands.
Our nine packing lines package a range of products ranging from 50g to 25kg. Each packing line has its own computer that informs the Line Leader of the current and subsequent productions, providing full details of the product, packaging and stacking requirements. Each production run has its own unique works order traced by RFID (Radio Frequency Identification) preventing any unforeseen human error, and offering full traceability for the partner. Before the line is run, the Line Operator checks the product is correct as per the specification, using a reference photo on the screen and should the product not be the exact standard is it rejected and a quality investigation commences. The bags are also placed horizontally into the machine and passed through a camera that checks the imagery of the bag, confirming it is correct.
Next, the bags are laser coded prior to filling, with various information being etched onto the bag in exactly the same place every time offering a guarantee that nothing will be missing or unreadable.
Weighing System & Quality Control
Meanwhile, the product is fed onto a weighing system into an arrangement of small buckets. After the weighing system has calculated the desired weight it releases a number of the buckets, dispensing the desired weight. Should the machine calculate an incorrect weight, a bypass system operates and the product is diverted away from the filling tube. If the weight is correct the product travels down a feeding tube and on its journey will pass through a metal detector. Should the machine detect a foreign object the machine will sound an alarm and a quality system process will begin an investigation into the source of the object. Once removed, the machine will restart and filling will resume.
Sealing the bag
The bag travels past a Thermal Camera which is used to guarantee the bag has been sealed. The camera uses thermal imagery to inspect the seal integrity. If the bag seal is faulty, the machine automatically rejects the bag, removing it from the process.
On Line Weight Checking System
Every bag passes across an On Line Weight Checking System that weighs every single bag, guaranteeing the weight. The same system will automatically reject any bag found to be under or overweight.
The bag travels through an x-ray system to check for metal or foreign bodies. Every bag is photographed for reference and anything detected will result in the bag being automatically rejected with a full investigation taking place.
The bag enters a fully automated bailing machine that will first index the bags to the partner’s requirement, for example 2 x 2. Once indexing is complete the bundle will move forward and become vertically wrapped in stretch film before going through the same process to be horizontally wrapped. This is so the bundle is fully encased, secure and protected. As the completed bundle exits the bailing machine, it passes an automatic bail label applicator that places the partner label onto the outside of the bundle. The data on the label is automatically generated by the main control computer, eliminating any potential human error. The bags are then fed into the automated palletiser machine. This huge machine will do a variety of functions resulting in a completed pallet at the end of the process. Finally, we automatically apply a label to the pallet. Whilst this is done the roller conveyor the pallet stands on records the weight of the pallet. The pallet is now taken to our storage facility ready for the partner to order.
