Automated processes are normal practice within the meals business. Production effectivity isn’t the only motivation, hygiene also plays a key function within 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 meet these necessities and incorporate each these objectives.
Question: How are high requirements of hygiene met by DEPRAG?

Answer: In order to make certain that the right drive is chosen to meet the excessive necessities for hygiene in the meals business, we usually suggest our ADVANCED LINE air vane motors. All their exterior elements are produced from stainless-steel and are impervious to regular cleansing brokers. The easy floor of these air motors is easy to wash. The drives are so nicely sealed with durable 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 generally used cleaning spray methods. A wet setting is no concern for this motor. It can even be used underwater as within the case of many stirring functions. All our ADVANCED LINE chrome steel motors are lubricated with meals grade USDA-H1 grease and may be operated oil-free. A energy reduction of approx. 10-20% based on the technical information said within the product catalog must be taken into account when designing drives for oil-free operation.
Question: Does an air motor must boast other features for such applications?

Answer: Yes. In many applications, condensation can kind in air supply lines. It is therefore advisable that measures are taken to ensure that the motor just isn’t situated at the lowest point in the system and that it can be flushed out with water. Many users take precautionary measures, not only referring to the format of the motor in their system, but in addition regarding the use of water separators or dryers in entrance of the drive. If all this is not attainable, then we recommend a particular coating for these parts within the motor’s inside that are produced from stainless steel. This is as a result of there’s a restrict to using stainless-steel for heavy obligation, high-speed internal parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you’ve any examples of the place your motors can be utilized in the meals industry?

Answer: Stirring dough, moving and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food business purposes are endless. I’ll describe a couple of applications in additional detail, similar to using 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 velocity of seven-hundred rpm.
We also have the ideal drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy within the smallest of spaces. The 900W high-torque motor with a nominal pace of twenty-two rpm overcomes a starting torque of 585 Nm and has a maximum diameter of 63 mm.
Another software may be present in grinding mills and conveying techniques for grain processing. In this case, the primary focus is on mud era and explosion prevention. All our ADVANCED LINE motors are ATEX licensed for use in doubtlessly explosive environments. You will even find our motors used within 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 wooden skewer via items of meat, onion and pepper. Pressure at the skewer is 38 kg and subsequently 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 principle benefits is its high energy density. Depending on the design, an air motor has solely a fifth of the mass of an electric motor, or a third of its size. This is especially vital when utilizing a handheld gadget but in fact also for robotic techniques the place the drive moves with the robotic arm.
Heat also leaves the air motor chilly. In crucial settings, compressed air is an unproblematic supply of power – it does not evaluate to the dangers 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 loads. There isn’t any downside with load being utilized on the air motor till standstill, no damages are incurred. This means it’s much less apt to stalling. After reduction of the load, it will run once more instantly and any number of successive times. Air motor power may be adapted simply by adjusting the working stress. The pace is decreased easily by throttling the air volume. Throttling provide air is really helpful when torque must also be significantly decreased. Exhaust air throttling ought to be chosen to scale back velocity with none critical affect on the torque.
Question: Air motors are often seen to be much 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 at all times depends on the circumstances of the appliance. Let me use this example to elucidate: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is utilized at decreased velocity over an extended time period to safe the packaging tape. Electric motors cannot be loaded over an extended time frame without operating the chance of overheating. Therefore, for this packaging machine, an electric motor would want to withstand high loads and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally totally different story with the air motor: Due to the favourable torque characteristics of air motors, a lower-powered drive will suffice. You may 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 near idle velocity at 450 rpm underneath mild load. The power required for this air motor is subsequently only 430W. The power steadiness of an air motor is seen in a very completely different mild when you suppose about that the air motor needed for this packaging machine would only require a 3rd of the facility of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on decades of expertise in the subject of air motors. They have a variety of top of the range, globally well-liked industrial drive options. 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 a long time and our normal program has been adjusted to fulfill the wants of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program.
