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

Automated processes are commonplace follow in the food trade. Production effectivity is not the one motivation, hygiene additionally plays a key position in the meals business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss tips on how to design a drive to fulfill these necessities and incorporate both these targets.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to ensure that the proper drive is selected to fulfill the high necessities for hygiene in the food trade, we often advocate our ADVANCED LINE air vane motors. All their exterior parts are created from stainless steel and are impervious to regular cleansing brokers. The smooth floor of these air motors is easy to scrub. 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 solutions can penetrate the motor. The motors are even resistant to water penetration from generally used cleansing spray techniques. A wet surroundings is no concern for this motor. It may even be used underwater as in the case of many stirring functions. 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 knowledge said within the product catalog must be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor need to boast different options for such applications?
Answer: Yes. In many functions, condensation can type in air provide lines. It is therefore advisable that measures are taken to ensure that the motor is not situated on the lowest point in 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 concerning the use of water separators or dryers in front of the drive. If all this isn’t possible, then we recommend a particular coating for these elements within the motor’s inside that are made from stainless-steel. This is as a end result of there is a restrict to using stainless-steel for heavy responsibility, high-speed inner parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you have any examples of where your motors can be used within the food industry?
Answer: Stirring dough, shifting and cutting sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals industry purposes are countless. I’ll describe a number of applications in additional 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 at the velocity of seven-hundred rpm.
We even have the ideal drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy within the smallest of areas. 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 63 mm.
Another software may be found in grinding mills and conveying methods for grain processing. In this case, the major focus is on dust era and explosion prevention. All our ADVANCED LINE motors are ATEX certified to be used in doubtlessly explosive environments. You will even find 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 through items 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 advantages does an air motor have over an electrical motor in such applications?
Answer: There are many arguments in favour of utilizing an air motor: One of the principle advantages is its excessive 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 measurement. This is especially vital when using a handheld device however after all also for robotic methods the place the drive strikes with the robot arm.
Heat additionally leaves the air motor cold. In crucial settings, compressed air is an unproblematic supply of energy – it does not examine to the dangers of electrical energy. The energy output from the air motor over wide torque ranges is almost fixed. Air motors can due to this fact be optimally operated in a large subject of fluctuating hundreds. There is no downside with load being utilized on the air motor until 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 times. Air motor power may be tailored just by adjusting the operating stress. The speed is lowered easily by throttling the air quantity. Throttling provide air is really helpful when torque should also be considerably lowered. Exhaust air throttling must be chosen to reduce back velocity 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 basis. The effectivity of a drive at all times is dependent upon the circumstances of the applying. Let me use this instance to explain: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is applied at decreased velocity over an extended time period to secure the packaging tape. Electric motors cannot be loaded over a long time frame without running the chance of overheating. Therefore, for this packaging machine, an electric motor would wish to resist excessive hundreds and as a result would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very different story with the air motor: Due to the beneficial torque characteristics of air motors, a lower-powered drive will suffice. You might choose an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since the working torque is below that of the nominal torque, the air motor runs close to idle velocity at 450 rpm underneath gentle load. The energy required for this air motor is therefore only 430W. The power balance of an air motor is seen in a very completely different mild when you consider that the air motor wanted for this packaging machine would solely require a third of the ability of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on decades of experience in the field of air motors. They have a wide range of top of the range, globally in style industrial drive solutions. Are the ADVANCED LINE motors a particular solution for food business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our standard program has been adjusted to meet the needs of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects benefit from long-established reliable drive solutions for the food business and medical technology.
