Automated processes are standard apply in the food trade. Production efficiency isn’t the one motivation, hygiene also plays a key function within the food industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to satisfy these necessities and incorporate each these targets.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to ensure that the right drive is selected to fulfill the high necessities for hygiene within the food industry, we often advocate our ADVANCED LINE air vane motors. All their external parts are produced from stainless steel and are impervious to normal cleansing brokers. The smooth surface of those air motors is straightforward to scrub. The drives are so well sealed with sturdy 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 proof against water penetration from generally used cleansing spray methods. A moist environment is no 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 power discount of approx. 10-20% based mostly on the technical data said within the product catalog must be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor must boast other options for such applications?
Answer: Yes. In many purposes, condensation can type in air supply traces. It is therefore advisable that measures are taken to make certain that the motor isn’t located on the lowest point in 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 in their system, but in addition concerning using water separators or dryers in entrance of the drive. If all this isn’t possible, then we recommend a special coating for these parts inside the motor’s inside that are produced from stainless steel. This is because there is a restrict to using chrome steel for heavy responsibility, high-speed inner elements. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you might have any examples of the place your motors can be utilized in the meals industry?
Answer: Stirring dough, moving and slicing sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals business purposes are infinite. I’ll describe a few applications in additional element, such as using 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 at the velocity of 700 rpm.
We even have the best drive for high-torque necessities 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 velocity of 22 rpm overcomes a beginning torque of 585 Nm and has a most diameter of sixty three mm.
Another application may be found in grinding mills and conveying techniques for grain processing. In this case, the focus is on mud technology and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in potentially explosive environments. You will even discover 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 through items of meat, onion and pepper. Pressure on the skewer is 38 kg and due to this fact 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 principle advantages is its excessive 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 especially important when using a handheld device however of course additionally for robotic systems the place the drive strikes with the robotic arm.
Heat additionally leaves the air motor chilly. In critical settings, compressed air is an unproblematic source of power – it doesn’t compare to the dangers of electrical energy. The power output from the air motor over extensive torque ranges is nearly fixed. Air motors can therefore be optimally operated in a large area of fluctuating masses. There isn’t any drawback with load being utilized on the air motor until standstill, no damages are incurred. This means it is much less apt to stalling. After discount of the load, it will run again immediately and any variety of successive times. Air motor power could be adapted simply by adjusting the operating stress. The speed is decreased smoothly by throttling the air volume. Throttling supply air is beneficial when torque must also be considerably reduced. Exhaust air throttling ought to be chosen to scale back velocity without any critical affect on the torque.
Question: Air motors are often seen to be much less environment friendly compared to electric motors. Can you comment on this statement?
Answer: Air motors and electric motors cannot be compared on a one-to-one foundation. The efficiency of a drive all the time is decided by the situations of the applying. 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 a protracted time frame to secure the packaging tape. Electric motors cannot be loaded over a long period of time without working the risk of overheating. Therefore, for this packaging machine, an electric motor would need to resist high masses and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally completely different story with the air motor: Due to the beneficial torque characteristics of air motors, a lower-powered drive will suffice. You might choose 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 pace at 450 rpm beneath light 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 gentle when you suppose about that the air motor wanted for this packaging machine would only require a 3rd of the ability of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on many years of experience in the area of air motors. They have a wide range of prime of the range, globally in style industrial drive options. Are the ADVANCED LINE motors a special solution 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 satisfy the needs of our customers. pressure gauge ไท วัสดุ belong to our DEPRAG catalog program.
