Ensure top-notch reliability with the right drive for the job

Automated processes are commonplace apply within the meals industry. Production effectivity isn’t the one motivation, hygiene additionally plays a key role in the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to fulfill these necessities and incorporate both these objectives.
Question: How are high requirements of hygiene met by DEPRAG?
Answer: In order to guarantee that the best drive is selected to meet the excessive necessities for hygiene in the food business, we normally advocate our ADVANCED LINE air vane motors. All their exterior components are produced from stainless steel and are impervious to regular cleansing agents. The clean floor of those air motors is straightforward to scrub. The drives are so well sealed with durable long-life radial shaft seals that no air can escape and equally no dust, water or different solutions can penetrate the motor. The motors are even proof against water penetration from commonly used cleaning spray methods. A wet setting isn’t any concern for this motor. It can even be used underwater as in the case of many stirring purposes. All our ADVANCED LINE stainless steel motors are lubricated with meals grade USDA-H1 grease and may be operated oil-free. A energy discount of approx. 10-20% primarily based on the technical information stated within 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 type in air supply traces. It is subsequently advisable that measures are taken to ensure that the motor is not located on the lowest point within the system and that it can be flushed out with water. Many customers take precautionary measures, not solely regarding the layout of the motor in their system, but in addition regarding the use of water separators or dryers in front of the drive. If all this is not attainable, then we recommend a particular coating for these elements within the motor’s interior which are made from chrome steel. This is because there’s a restrict to using chrome steel for heavy obligation, high-speed internal parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you might have any examples of the place your motors can be used within the food industry?
Answer: Stirring dough, moving and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food trade functions are infinite. I’ll describe a quantity of functions in additional detail, similar to the utilization of our ADVANCED LINE air motor in an agitator for the production 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 best drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power within the smallest of areas. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a starting torque of 585 Nm and has a most diameter of sixty three mm.
Another software can be present in grinding mills and conveying techniques for grain processing. In this case, the primary focus is on dust generation and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in probably explosive environments. You will even discover our motors used in the processing of meat, for instance 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 wood skewer by way of pieces of meat, onion and pepper. Pressure on the skewer is 38 kg and subsequently 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 using an air motor: One of the principle benefits is its high energy density. Depending on the design, an air motor has only a fifth of the mass of an electrical motor, or a third of its size. This is especially important when using a handheld device but after all also for robotic systems where the drive moves with the robot arm.
Heat also leaves the air motor cold. In critical settings, compressed air is an unproblematic supply of power – it doesn’t evaluate to the risks of electricity. The energy output from the air motor over wide torque ranges is nearly constant. Air motors can due to this fact be optimally operated in a wide subject of fluctuating hundreds. There is not any problem with load being applied on the air motor until standstill, no damages are incurred. This means it’s less apt to stalling. After reduction of the load, it’s going to run once more instantly and any number of successive occasions. Air motor energy can be adapted simply by adjusting the working pressure. The velocity is lowered easily by throttling the air quantity. Throttling provide air is really helpful when torque should also be considerably reduced. Exhaust air throttling ought to be chosen to minimize back speed with none critical influence on the torque.
Question: Air motors are often seen to be less environment friendly compared to electric motors. Can you comment on this statement?
Answer: Air motors and electrical motors can’t be compared on a one-to-one foundation. The effectivity of a drive always is determined by the conditions of the applying. Let me use this instance to elucidate: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is applied at reduced velocity over a protracted period of time to secure the packaging tape. Electric motors cannot be loaded over a long time period without running the chance of overheating. Therefore, for this packaging machine, an electric motor would need to resist excessive masses and in consequence would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely completely different story with the air motor: Due to the beneficial torque traits of air motors, a lower-powered drive will suffice. You could select an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since the working torque is beneath that of the nominal torque, the air motor runs close to idle speed at 450 rpm underneath light load. The energy required for this air motor is subsequently solely 430W. The energy balance of an air motor is seen in a completely completely different gentle when you consider that the air motor wanted for this packaging machine would only require a third of the power of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on many years of experience within the subject of air motors. They have a variety of high quality, 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 many years and our standard program has been adjusted to meet the needs of our customers. Easy belong to our DEPRAG catalog program. Our prospects benefit from long-established reliable drive options for the food industry and medical know-how. We are in a position to offer these motors in a large energy range from 20 W to 1.6 kW combined with a big selection of planetary gears from our personal production with speeds of 7 to 24,000 rpm.
