Automated processes are commonplace follow in the meals trade. Production efficiency just isn’t the only motivation, hygiene additionally performs a key position in the food trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss tips on how to design a drive to meet these necessities and incorporate both these goals.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to guarantee that the proper drive is chosen to meet the excessive necessities for hygiene within the food trade, we often suggest our ADVANCED LINE air vane motors. All their external parts are created from chrome steel and are impervious to normal cleaning brokers. The easy floor of these air motors is straightforward to wash. The drives are so nicely sealed with durable long-life radial shaft seals that no air can escape and equally no dirt, water or other options can penetrate the motor. The motors are even proof against water penetration from generally used cleaning spray techniques. A wet environment isn’t any concern for this motor. It can even be used underwater as in the case of many stirring applications. All our ADVANCED LINE stainless steel motors are lubricated with food grade USDA-H1 grease and could be operated oil-free. A power reduction of approx. 10-20% primarily based on the technical knowledge acknowledged in the product catalog should be taken into account when designing drives for oil-free operation.
Question: Does an air motor have to boast different features for such applications?
Answer: Yes. In many applications, condensation can kind in air provide lines. It is subsequently advisable that measures are taken to ensure that the motor is not located at the lowest point within the system and that it can be flushed out with water. Many customers take precautionary measures, not only referring to the layout of the motor of their system, but also regarding using water separators or dryers in front of the drive. If all this isn’t possible, then we suggest a particular coating for these parts within the motor’s inside which are created from stainless-steel. This is as a end result of there is a limit to using stainless-steel for heavy responsibility, high-speed inside elements. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you might have any examples of the place your motors can be utilized within the food industry?
Answer: Stirring dough, moving and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food trade functions are endless. I’ll describe a few purposes in more detail, corresponding to the usage of our ADVANCED LINE air motor in an agitator for the manufacturing of fruit juice. Our 300W air motor drives a propeller stirrer in a magnetic agitator on the speed of seven-hundred rpm.
We even have the ideal drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in the smallest of areas. The 900W high-torque motor with a nominal pace of 22 rpm overcomes a starting torque of 585 Nm and has a most diameter of sixty three mm.
Another utility could be found in grinding mills and conveying methods for grain processing. In this case, the major target is on mud generation and explosion prevention. All our ADVANCED LINE motors are ATEX certified to be used in potentially explosive environments. You will even find our motors used within the processing of meat, for example in a semi-automatic meeting system for the manufacture of kebab skewers. In the skewer unit, two air motors are used to drive belts which pierce a picket skewer by way of pieces of meat, onion and pepper. Pressure on the skewer is 38 kg and therefore a high-power air motor with compact design is ideally suited to this utility.
Question: What benefits does an air motor have over an electric motor in such applications?
Answer: There are many arguments in favour of utilizing an air motor: One of the principle advantages is its high energy density. Depending on the design, an air motor has only a fifth of the mass of an electric motor, or a third of its size. This is particularly significant when using a handheld system however in fact additionally for robotic methods the place the drive strikes with the robotic arm.
Heat additionally leaves the air motor cold. In critical settings, compressed air is an unproblematic supply of power – it doesn’t evaluate to the hazards of electricity. The power output from the air motor over broad torque ranges is nearly constant. Air motors can due to this fact be optimally operated in a wide field of fluctuating masses. There is no downside with load being applied on the air motor till standstill, no damages are incurred. This means it is less apt to stalling. After reduction of the load, it will run once more instantly and any variety of successive occasions. Air motor energy could be tailored simply by adjusting the operating strain. The pace is reduced smoothly by throttling the air quantity. Throttling supply air is really helpful when torque must also be significantly reduced. Exhaust air throttling must be chosen to minimize back pace without any severe affect on the torque.
Question: Air motors are sometimes seen to be less environment friendly compared to electric motors. Can you touch upon this statement?
Answer: Air motors and electrical motors can’t be compared on a one-to-one basis. The effectivity of a drive at all times is dependent upon the conditions of the appliance. Let me use this example to clarify: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is utilized at lowered pace over an extended period of time to secure the packaging tape. Electric motors can’t be loaded over a protracted period of time with out working the chance of overheating. Therefore, for this packaging machine, an electrical motor would want to withstand high loads and as a result would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a very completely different story with the air motor: Due to the beneficial torque traits of air motors, a lower-powered drive will suffice. You may select an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since เกจวัดแรงดันออกซิเจนราคา working torque is under that of the nominal torque, the air motor runs near idle velocity at 450 rpm under gentle load. The energy required for this air motor is therefore solely 430W. The power stability of an air motor is seen in a very totally different gentle when you think about that the air motor wanted for this packaging machine would only require a 3rd of the facility of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on a long time of experience within the field of air motors. They have a variety of high of the range, globally in style industrial drive solutions. Are the ADVANCED LINE motors a particular resolution for meals business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the decades and our commonplace program has been adjusted to fulfill the needs of our customers.
