Application of different types of Rubber Air Hose
We should know that if you are not using a food-grade hose now, please do not hesitate to replace it, because it causes harm to our body.Now, ORIENTFLEX will tell you what a food-grade hose is and how to clear it.
How To Choose Food Grade Hose
1.THE RIGHT DIAMETER
The diameter of the food grade hose depends on the stainless steel line and the tank or filling machine to which the hose has to be connected. The diameter of the couplings that are used for this determines the diameter of the hose. This should, of course, be the same. In some instances, the diameter of the stainless steel line and the diameter of the filling machine are not the same. In this case, an adapter will be installed on the food grade hose that is placed between the stainless steel line and the filling machine. This adapter can be welded or screwed in place. A screwed adapter is preferred because it is more hygienic. An adapter with a welded seam offers an easy place for bacteria to accumulate.
2.SANITARY COUPLING OR CLAMP
The coupling between the food grade hose and the stainless steel line, filling machine or tank can take the form of a sanitary coupling– also referred to as a dairy coupling – or a clamp. The advantage of a clamp is that it can be used more flexibly. The user can screw it on and off the hose by hand. A sanitary coupling is pushed onto the hose by a specialist.
The advantage of a sanitary coupling is that it is more hygienic. Bacteria cannot easily accumulate on it. They can do so more quickly on a clamp due to the use of screws. In addition, a sanitary coupling is safer because it is professionally pushed into place and thus connects firmly to the hose. A clamp is tightened by hand, can deform the hose and can pop off if not properly fastened.
Obviously, the clamp is cheaper to buy and is often used on hoses that transport unprocessed products at low pressure, such as raw milk that is pumped from the milk tank on the farm to the milk tanker and then from the tanker to the storage tank at the milk factory. In the food treatment process – i.e. in the factory – the preference is for sanitary couplings for reasons of hygiene and safety.
