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

Automated processes are standard practice in the food trade. Production effectivity is not 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 fulfill these necessities and incorporate each these goals.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to guarantee that the best drive is chosen to meet the excessive requirements for hygiene in the food trade, we usually suggest our ADVANCED LINE air vane motors. All their exterior elements are produced from stainless steel and are impervious to normal cleansing agents. The easy surface of these air motors is simple to scrub. The drives are so well sealed with durable long-life radial shaft seals that no air can escape and equally no dirt, water or different solutions can penetrate the motor. The motors are even immune to 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 within the case of many stirring applications. All our ADVANCED LINE stainless steel motors are lubricated with food grade USDA-H1 grease and may be operated oil-free. A energy reduction of approx. 10-20% based mostly on the technical data stated within the product catalog must be taken into account when designing drives for oil-free operation.
Question: Does an air motor must boast different features for such applications?
Answer: Yes. In many applications, condensation can form in air supply traces. It is due to this fact advisable that measures are taken to make sure that the motor isn’t located on the lowest point in the system and that it could 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 using water separators or dryers in entrance of the drive. If all this is not potential, then we advocate a particular coating for these elements inside the motor’s inside that are produced from stainless steel. This is because there is a limit to the use of stainless-steel for heavy obligation, high-speed inside elements. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you might have any examples of where your motors can be utilized within the meals industry?
Answer: Stirring dough, transferring and cutting sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food industry purposes are countless. I’ll describe a number of purposes in additional 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 on the velocity of seven-hundred rpm.
เกจ์ออกซิเจนsumo have the perfect drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in the smallest of spaces. The 900W high-torque motor with a nominal velocity of 22 rpm overcomes a starting torque of 585 Nm and has a maximum diameter of sixty three mm.
Another software may be found in grinding mills and conveying methods for grain processing. In this case, the primary focus is on mud technology and explosion prevention. All our ADVANCED LINE motors are ATEX licensed for use in potentially explosive environments. You will even find our motors used in the processing of meat, for instance 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 through items of meat, onion and pepper. Pressure at 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 electric motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the primary advantages is its high energy density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a third of its measurement. This is especially significant when utilizing a handheld system however after all also for robotic methods where the drive strikes with the robot arm.
Heat additionally leaves the air motor cold. In critical settings, compressed air is an unproblematic source of energy – it doesn’t evaluate to the risks of electrical energy. The energy output from the air motor over wide torque ranges is nearly fixed. Air motors can therefore be optimally operated in a wide area of fluctuating hundreds. There isn’t any downside with load being applied on the air motor till standstill, no damages are incurred. This means it is much less apt to stalling. After discount of the load, it’s going to run once more instantly and any number of successive occasions. Air motor energy could be adapted just by adjusting the working pressure. The pace is reduced easily by throttling the air quantity. Throttling provide air is recommended when torque also wants to be significantly lowered. Exhaust air throttling must be chosen to scale back pace without any critical affect on the torque.
Question: Air motors are often seen to be less environment friendly in comparison with electrical motors. Can you touch upon this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one foundation. The effectivity of a drive always is decided by the circumstances 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 speed over a protracted period of time to safe the packaging tape. Electric motors can’t be loaded over an extended period of time without operating the risk of overheating. Therefore, for this packaging machine, an electric motor would wish to withstand excessive loads and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely completely different story with the air motor: Due to the favourable torque characteristics 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 below that of the nominal torque, the air motor runs close to idle pace at 450 rpm underneath mild load. The energy required for this air motor is due to this fact solely 430W. The vitality stability of an air motor is seen in a completely completely different light when you suppose about that the air motor needed for this packaging machine would only require a third of the ability of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on a long time of expertise in the subject of air motors. They have a variety of high of the range, globally popular industrial drive options. Are the ADVANCED LINE motors a particular answer 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 normal program has been adjusted to fulfill the wants of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects benefit from long-established reliable drive options for the food industry and medical technology. We are able to offer these motors in a wide energy range from 20 W to 1.6 kW combined with a selection of planetary gears from our own production with speeds of 7 to 24,000 rpm.
