Automated processes are standard apply in the food trade. Production efficiency isn’t the only motivation, hygiene also plays a key role 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 satisfy these requirements and incorporate both these objectives.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to ensure that the best drive is chosen to meet the excessive requirements for hygiene within the meals trade, we normally advocate our ADVANCED LINE air vane motors. All their exterior components are created from chrome steel and are impervious to regular cleansing brokers. The easy surface of those air motors is straightforward to wash. The drives are so properly sealed with durable long-life radial shaft seals that no air can escape and equally no dirt, water or different options can penetrate the motor. The motors are even proof against water penetration from generally used cleansing spray methods. A moist setting is no concern for this motor. It may even be used underwater as in the case of many stirring applications. All our ADVANCED LINE chrome steel motors are lubricated with food grade USDA-H1 grease and can be operated oil-free. A energy discount of approx. 10-20% primarily based on the technical knowledge said in the product catalog should be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor must boast other features for such applications?
Answer: Yes. In many functions, condensation can form in air provide strains. It is therefore advisable that measures are taken to ensure that the motor is not situated at the lowest point in the system and that it may be flushed out with water. Many customers take precautionary measures, not only referring to the format of the motor of their system, but also regarding the use of water separators or dryers in front of the drive. If all this isn’t attainable, then we advocate a particular coating for those elements within the motor’s inside which are produced from chrome steel. This is as a end result of there’s a restrict to the use of stainless steel for heavy duty, high-speed internal elements. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you have any examples of where your motors can be utilized within the food industry?
Answer: Stirring dough, transferring and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals trade applications are countless. I’ll describe a couple of applications in additional detail, such as 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 at the speed of seven-hundred rpm.
We even have the best drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power in the smallest of spaces. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of sixty three mm.
Another utility can be found in grinding mills and conveying methods for grain processing. In this case, the focus is on dust era and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in doubtlessly explosive environments. You will even discover our motors used in the processing of meat, for example 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 wooden skewer through items of meat, onion and pepper. Pressure on 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 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 power density. Depending on the design, an air motor has solely a fifth of the mass of an electric motor, or a third of its measurement. This is especially important when using a handheld gadget however after all additionally for robotic systems the place the drive moves with the robotic arm.
Heat additionally leaves the air motor cold. In crucial settings, compressed air is an unproblematic source of power – it doesn’t examine to the dangers of electrical energy. The energy output from the air motor over extensive torque ranges is almost fixed. Air motors can due to this fact be optimally operated in a large area of fluctuating masses. 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 reduction of the load, it’s going to run once more immediately and any number of successive instances. Air motor energy could be tailored just by adjusting the operating strain. The velocity is lowered smoothly by throttling the air quantity. Throttling supply air is recommended when torque must also be significantly lowered. Exhaust air throttling must be chosen to minimize back speed with none critical affect on the torque.
Question: Air motors are often seen to be less efficient compared to electric motors. Can เพรสเชอร์เกจวัดแรงดันน้ำ comment on this statement?
Answer: Air motors and electrical motors cannot be in contrast on a one-to-one basis. The effectivity of a drive all the time depends on the circumstances of the application. 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 applied at lowered speed over a protracted time period to safe the packaging tape. Electric motors can’t be loaded over a protracted time period with out operating the danger of overheating. Therefore, for this packaging machine, an electric motor would need to withstand high masses and as a result would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally different story with the air motor: Due to the favourable torque traits of air motors, a lower-powered drive will suffice. You could select an air motor with a nominal torque of 15 Nm and nominal velocity of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs close to idle velocity at 450 rpm underneath light load. The power required for this air motor is due to this fact solely 430W. The energy steadiness of an air motor is seen in a completely completely different gentle when you think about that the air motor wanted for this packaging machine would solely require a 3rd of the power of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on decades of experience in the subject of air motors. They have a wide range of top of the range, globally in style industrial drive options. Are the ADVANCED LINE motors a special resolution for food trade 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 clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects profit from long-established reliable drive solutions for the food business and medical know-how. We are able to supply these motors in a large power vary from 20 W to 1.6 kW mixed with a selection of planetary gears from our own manufacturing with speeds of 7 to 24,000 rpm.
