Automated processes are commonplace apply within the food trade. Production efficiency isn’t the only motivation, hygiene also plays a key function in the food industry. 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 each these targets.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to ensure that the proper drive is selected to meet the excessive necessities for hygiene within the meals business, we often advocate our ADVANCED LINE air vane motors. All their external components are produced from stainless steel and are impervious to regular cleansing agents. The smooth floor of those air motors is straightforward to scrub. The drives are so well sealed with durable long-life radial shaft seals that no air can escape and equally no filth, water or different options can penetrate the motor. The motors are even proof against water penetration from commonly used cleansing spray methods. A wet setting is not any concern for this motor. It can even be used underwater as within the case of many stirring purposes. All our ADVANCED LINE stainless-steel motors are lubricated with meals grade USDA-H1 grease and could be operated oil-free. A power reduction of approx. 10-20% based on the technical information stated within the product catalog ought to be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor need to boast different options for such applications?
Answer: Yes. In ไดอะแฟรม ซีล , condensation can type in air provide traces. It is therefore advisable that measures are taken to guarantee that the motor is not positioned at the lowest point in the system and that it could be flushed out with water. Many users take precautionary measures, not solely referring to the format of the motor of their system, but also regarding using water separators or dryers in entrance of the drive. If all this is not attainable, then we advocate a particular coating for these components throughout the motor’s inside that are made from stainless steel. This is as a end result of there’s a limit to the use of chrome 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 used 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 meals trade functions are countless. I’ll describe a few purposes in additional detail, corresponding to the use of our ADVANCED LINE air motor in an agitator for the manufacturing of fruit juice. Our 300W air motor drives a propeller stirrer in a magnetic agitator on the pace of seven hundred rpm.
We also 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 pace of 22 rpm overcomes a starting torque of 585 Nm and has a most diameter of sixty three mm.
Another utility may be found in grinding mills and conveying methods for grain processing. In this case, the primary focus is on dust technology and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in doubtlessly 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 picket skewer by way of 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 benefits 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 only a fifth of the mass of an electric motor, or a third of its dimension. This is particularly significant when using a handheld device however after all additionally for robotic techniques where the drive strikes with the robot arm.
Heat additionally leaves the air motor chilly. In critical settings, compressed air is an unproblematic supply of power – it does not evaluate to the dangers of electrical energy. The power output from the air motor over wide torque ranges is nearly fixed. Air motors can due to this fact be optimally operated in a large subject of fluctuating hundreds. There isn’t any problem with load being utilized on the air motor until standstill, no damages are incurred. This means it’s less apt to stalling. After discount of the load, it’ll run once more immediately and any variety of successive times. Air motor energy may be tailored just by adjusting the operating stress. The velocity is reduced smoothly by throttling the air volume. Throttling supply air is really helpful when torque should also be considerably lowered. Exhaust air throttling ought to be chosen to reduce pace without any serious influence on the torque.
Question: Air motors are often seen to be much less environment friendly compared to electrical motors. Can you comment on this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one basis. The effectivity of a drive always depends on the conditions of the application. Let me use this example to explain: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at lowered pace over a protracted time frame to safe the packaging tape. Electric motors cannot be loaded over a protracted period of time with out operating the chance of overheating. Therefore, for this packaging machine, an electric motor would want to withstand excessive 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 beneficial torque traits 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 beneath gentle load. The power required for this air motor is subsequently only 430W. The power stability of an air motor is seen in a totally completely different mild when you consider that the air motor wanted for this packaging machine would only require a third of the facility of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on a long time of experience within the field of air motors. They have a broad range of excessive quality, globally popular industrial drive options. Are the ADVANCED LINE motors a special answer for meals industry applications?
Answer: It is true that our engineers have continued to optimise our air motors over the decades and our standard program has been adjusted to satisfy the wants of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers benefit from long-established dependable drive solutions for the food industry and medical technology.
