Automated processes are normal follow within the food trade. Production effectivity just isn’t the only motivation, hygiene additionally performs a key function in the meals business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate tips on how to design a drive to meet these requirements and incorporate each these targets.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to make certain that the proper drive is selected to meet the excessive requirements for hygiene within the food industry, we usually suggest our ADVANCED LINE air vane motors. All their exterior parts are produced from chrome steel and are impervious to normal cleansing brokers. The easy surface of these air motors is straightforward to clean. The drives are so nicely sealed with durable long-life radial shaft seals that no air can escape and equally no dust, water or different options can penetrate the motor. The motors are even resistant to water penetration from commonly used cleansing spray systems. A moist setting 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 may be operated oil-free. A energy discount of approx. 10-20% based mostly on the technical knowledge acknowledged within the product catalog ought to be taken under 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 applications, condensation can kind in air provide lines. It is subsequently advisable that measures are taken to ensure that the motor isn’t positioned at the lowest point within the system and that it can be flushed out with water. Many users take precautionary measures, not solely referring to the format of the motor in their system, but additionally concerning the utilization of water separators or dryers in entrance of the drive. If all this is not possible, then we recommend a special coating for these components inside the motor’s interior that are created from stainless steel. This is because there is a restrict to using chrome steel for heavy responsibility, high-speed inside elements. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you could have any examples of where your motors can be utilized in the food industry?
Answer: Stirring dough, shifting and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals trade applications are countless. I’ll describe a couple of applications in additional detail, corresponding 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 best 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 pace of twenty-two rpm overcomes a beginning torque of 585 Nm and has a most diameter of sixty three mm.
Another application could be present in grinding mills and conveying methods for grain processing. In this case, the primary focus is on mud generation and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in potentially 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 by way of 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 application.
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 main 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 3rd of its measurement. This is particularly significant when utilizing a handheld gadget but after all also for robotic systems the place the drive moves with the robotic arm.
Heat also leaves the air motor cold. In important settings, compressed air is an unproblematic source of power – it does not compare to the dangers of electricity. The power output from the air motor over extensive torque ranges is nearly constant. pressure gauge ด้าน ดูด can subsequently be optimally operated in a wide subject of fluctuating loads. There is not any drawback 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’s going to run again immediately and any variety of successive instances. Air motor power can be adapted simply by adjusting the operating strain. The velocity is lowered easily by throttling the air quantity. Throttling provide air is beneficial when torque should also be considerably reduced. Exhaust air throttling should be chosen to scale back velocity with none serious influence on the torque.
Question: Air motors are often seen to be much less efficient compared to electrical motors. Can you comment on this statement?
Answer: Air motors and electrical motors can’t be compared on a one-to-one foundation. The efficiency of a drive all the time is determined by the circumstances of the application. Let me use this example to explain: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is utilized at decreased speed over an extended period of time to secure the packaging tape. Electric motors can’t be loaded over a long time period with out working the risk of overheating. Therefore, for this packaging machine, an electrical motor would wish to face up to excessive hundreds and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely different story with the air motor: Due to the favourable torque traits of air motors, a lower-powered drive will suffice. You may 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 close to idle pace at 450 rpm beneath gentle load. The energy required for this air motor is therefore only 430W. The power steadiness of an air motor is seen in a completely different mild when you consider that the air motor wanted for this packaging machine would only require a 3rd of the power of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on decades of expertise in the field of air motors. They have a variety of prime of the range, globally in style industrial drive options. Are the ADVANCED LINE motors a special resolution for meals industry applications?
