Automated processes are commonplace apply within the food business. Production effectivity just isn’t the only motivation, hygiene also plays a key position in the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to meet these necessities and incorporate each these targets.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to make certain that the best drive is selected to fulfill the excessive necessities for hygiene in the food trade, we usually advocate our ADVANCED LINE air vane motors. All their external parts are created from stainless-steel and are impervious to normal cleaning agents. The clean floor of these air motors is simple to wash. The drives are so nicely sealed with sturdy 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 immune to water penetration from commonly used cleansing spray techniques. A wet surroundings isn’t any concern for this motor. It can even be used underwater as in the case of many stirring functions. All our ADVANCED LINE stainless-steel motors are lubricated with food grade USDA-H1 grease and may be operated oil-free. A power reduction of approx. 10-20% based on the technical information said in the product catalog must be taken into account when designing drives for oil-free operation.
Question: Does an air motor have to boast other options for such applications?
Answer: Yes. In many purposes, condensation can type in air provide strains. It is due to this fact advisable that measures are taken to ensure that the motor is not situated on the lowest level within the system and that it can be flushed out with water. Many users take precautionary measures, not solely referring to the layout of the motor of their system, but in addition regarding the utilization of water separators or dryers in entrance of the drive. If all this isn’t possible, then we recommend a particular coating for these components inside the motor’s interior that are made from chrome steel. This is as a outcome of there is a restrict to the use of stainless-steel for heavy responsibility, high-speed inner components. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you may have any examples of the place your motors can be utilized within the food industry?
Answer: Stirring dough, moving and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals business applications are infinite. I’ll describe a couple of applications in more detail, such as 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 on the velocity of seven-hundred rpm.
We even have the perfect drive for high-torque requirements 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 starting torque of 585 Nm and has a most diameter of sixty three mm.
Another application can be present in grinding mills and conveying methods for grain processing. In this case, the focus is on dust generation and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in probably explosive environments. You will even find our motors used within 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 pieces 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 software.
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 benefits is its excessive power density. Depending on the design, an air motor has only a fifth of the mass of an electrical motor, or a 3rd of its size. This is particularly vital when utilizing a handheld system however in fact also for robotic techniques where the drive moves with the robotic arm.
Heat also leaves the air motor cold. In crucial settings, compressed air is an unproblematic supply of energy – it doesn’t evaluate to the hazards of electrical energy. The power output from the air motor over wide torque ranges is nearly constant. Air motors can subsequently be optimally operated in a large field of fluctuating hundreds. There isn’t any problem with load being utilized 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 immediately and any variety of successive times. Air motor power may be adapted simply by adjusting the working pressure. The speed is decreased easily by throttling the air volume. Throttling provide air is beneficial when torque should also be significantly decreased. Exhaust air throttling must be chosen to reduce velocity with none serious affect on the torque.
Question: Air motors are often seen to be much less efficient compared to electric motors. Can you touch upon this statement?
Answer: Air motors and electrical motors cannot be in contrast on a one-to-one foundation. The effectivity of a drive all the time depends on the situations of the applying. 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 utilized at reduced speed over a protracted time frame to safe the packaging tape. Electric motors can’t be loaded over a long time period with out running the risk of overheating. Therefore, for this packaging machine, an electrical motor would need to withstand high hundreds and consequently would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very totally 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 pace of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs near idle speed at 450 rpm under mild load. The energy required for this air motor is therefore only 430W. The energy steadiness of an air motor is seen in a totally totally different gentle when you consider that the air motor needed for this packaging machine would only require a third of the power of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on decades of expertise in the field of air motors. They have a extensive range of prime quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a special resolution for meals industry 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 wants of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients benefit from long-established reliable drive options for the meals industry and medical know-how.
