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

Automated processes are normal practice within the meals business. Production efficiency just isn’t the one motivation, hygiene also performs a key position within 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 satisfy these necessities and incorporate both these targets.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to ensure that the best drive is chosen to fulfill the excessive necessities for hygiene within the food trade, we normally recommend our ADVANCED LINE air vane motors. All their exterior parts are created from stainless-steel and are impervious to regular cleaning brokers. The clean surface of these air motors is simple to clean. The drives are so properly sealed with sturdy long-life radial shaft seals that no air can escape and equally no dust, water or other solutions can penetrate the motor. The motors are even immune to water penetration from commonly used cleaning spray systems. A moist environment isn’t any concern for this motor. It may even be used underwater as within the case of many stirring applications. All our ADVANCED LINE stainless steel motors are lubricated with food grade USDA-H1 grease and can be operated oil-free. A power reduction of approx. 10-20% based mostly on the technical data acknowledged in the product catalog must be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor need to boast different features for such applications?
Answer: Yes. In many applications, condensation can kind in air provide lines. It is therefore advisable that measures are taken to ensure that the motor just isn’t positioned at the lowest level in the system and that it might be flushed out with water. Many customers take precautionary measures, not only relating to the format of the motor in their system, but also regarding the use of water separators or dryers in entrance of the drive. If all this isn’t potential, then we suggest a special coating for those parts inside the motor’s interior that are produced from chrome steel. This is as a outcome of there’s a limit to the utilization of chrome steel for heavy responsibility, high-speed inside parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you’ve any examples of where your motors can be used in the meals industry?
Answer: Stirring dough, shifting and cutting sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals trade functions are endless. I’ll describe a quantity of purposes in more element, similar to the use 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 at the speed of 700 rpm.
We even have the perfect drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power in the smallest of spaces. The 900W high-torque motor with a nominal pace of 22 rpm overcomes a beginning torque of 585 Nm and has a most diameter of sixty three mm.
Another utility may be found in grinding mills and conveying methods for grain processing. In this case, the main focus is on mud generation and explosion prevention. All our ADVANCED LINE motors are ATEX licensed for use in probably explosive environments. You will even discover our motors used in the processing of meat, for example in a semi-automatic assembly system for the manufacture of kebab skewers. In the skewer unit, two air motors are used to drive belts which pierce a wood skewer via items of meat, onion and pepper. Pressure on the skewer is 38 kg and due to this fact a high-power air motor with compact design is ideally suited to this software.
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 main advantages is its high power density. Depending on the design, an air motor has only a fifth of the mass of an electric motor, or a 3rd of its dimension. This is particularly vital when utilizing a handheld device but of course additionally for robotic systems where the drive moves with the robot arm.
Heat also leaves the air motor chilly. In critical settings, compressed air is an unproblematic supply of energy – it doesn’t compare to the dangers of electricity. The power output from the air motor over wide torque ranges is almost constant. Air motors can therefore be optimally operated in a wide area of fluctuating hundreds. There is not any downside with load being utilized on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After discount of the load, it’ll run once more immediately and any number of successive occasions. Air motor power may be adapted just by adjusting the working stress. The speed is lowered easily by throttling the air quantity. Throttling provide air is recommended when torque must also be considerably decreased. Exhaust air throttling ought to be chosen to reduce speed without any critical influence on the torque.
Question: Air motors are often seen to be less efficient compared to electrical motors. Can you comment on this statement?
Answer: Air motors and electric motors cannot be compared on a one-to-one foundation. The effectivity of a drive at all times depends on the conditions of the appliance. Let me use this example 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 an extended time period to secure the packaging tape. Electric motors can’t be loaded over a long time period with out running the danger of overheating. Therefore, for this packaging machine, an electrical motor would want to resist high masses and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally completely different story with the air motor: Due to the favourable torque traits of air motors, a lower-powered drive will suffice. You might select an air motor with a nominal torque of 15 Nm and nominal velocity of 275 rpm. Since the working torque is beneath that of the nominal torque, the air motor runs near idle pace at 450 rpm under mild load. The energy required for this air motor is therefore only 430W. The power balance of an air motor is seen in a very different mild when you consider that the air motor wanted for this packaging machine would solely require a 3rd of the power of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on many years of expertise in the area of air motors. They have a broad range of high quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a particular answer for meals trade 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 satisfy the needs of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers benefit from long-established reliable drive solutions for the meals industry and medical technology.
