Automated processes are normal follow within the meals business. Production efficiency just isn’t the only motivation, hygiene also performs a key position within the food business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate the means to design a drive to fulfill these requirements and incorporate each these objectives.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to make sure that the proper drive is selected to satisfy the excessive requirements for hygiene within the meals industry, we often suggest our ADVANCED LINE air vane motors. All their exterior elements are created from stainless steel and are impervious to regular cleansing brokers. The easy floor of these air motors is easy to clean. The drives are so well 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 proof against water penetration from commonly used cleaning spray systems. A moist environment is not any concern for this motor. It can even be used underwater as within the case of many stirring functions. All our ADVANCED LINE stainless-steel motors are lubricated with meals grade USDA-H1 grease and can be operated oil-free. A power discount of approx. 10-20% based on the technical knowledge acknowledged in the product catalog ought to be taken into account when designing drives for oil-free operation.
Question: Does an air motor need to boast different options for such applications?
Answer: Yes. In many functions, condensation can form in air supply strains. It is due to this fact advisable that measures are taken to guarantee that the motor just isn’t situated on the lowest point in the system and that it can be flushed out with water. Many users take precautionary measures, not only relating to the structure of the motor in their system, but also concerning the use of water separators or dryers in entrance of the drive. If all this is not potential, then we recommend a special coating for these components inside the motor’s inside which are created from stainless steel. This is as a result of there’s a restrict to the use of chrome steel for heavy responsibility, high-speed inside components. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you have any examples of the place your motors can be utilized within the meals industry?
Answer: Stirring dough, transferring and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals business applications are countless. I’ll describe a few purposes in additional element, similar 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 even have the perfect drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power within 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 63 mm.
Another utility could be found in grinding mills and conveying systems for grain processing. In this case, the major focus is on mud era and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in probably explosive environments. You will even find our motors used within the processing of meat, for instance 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 wooden skewer via 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 utility.
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 solely a fifth of the mass of an electric motor, or a 3rd of its size. This is particularly significant when using a handheld device but in fact additionally for robotic systems the place the drive moves with the robotic arm.
Heat additionally leaves the air motor cold. In important settings, compressed air is an unproblematic supply of power – it doesn’t evaluate to the risks of electricity. The power output from the air motor over extensive torque ranges is kind of fixed. Air motors can due to this fact be optimally operated in a large subject of fluctuating masses. There is no problem with load being utilized on the air motor until standstill, no damages are incurred. This means it’s less apt to stalling. After reduction of the load, it will run again instantly and any number of successive times. Air motor energy could be tailored simply by adjusting the operating strain. The pace is lowered smoothly by throttling the air volume. Throttling supply air is beneficial when torque also needs to be considerably reduced. Exhaust air throttling ought to be chosen to minimize back velocity without any critical influence on the torque.
Question: Air motors are sometimes seen to be much less environment friendly compared to electrical motors. Can you touch upon this statement?
Answer: Air motors and electric motors can’t be in contrast on a one-to-one basis. The effectivity of a drive always is dependent upon 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 utilized at decreased pace over a long time frame to secure the packaging tape. Electric motors cannot be loaded over an extended time period without running the chance of overheating. Therefore, for this packaging machine, an electrical motor would want to face up to high masses and consequently would have to be 1170W (25 Nm x 450 rpm divided by 9550). pressure gauge ราคา is a completely different story with the air motor: Due to the beneficial torque characteristics 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 beneath that of the nominal torque, the air motor runs close to idle velocity at 450 rpm under mild load. The energy required for this air motor is due to this fact solely 430W. The vitality stability of an air motor is seen in a totally completely different gentle when you suppose about that the air motor needed for this packaging machine would solely require a third of the power of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on many years of experience within the area of air motors. They have a wide range of excessive quality, globally popular industrial drive options. Are the ADVANCED LINE motors a special solution for food industry applications?
Answer: It is true that our engineers have continued to optimise our air motors over the decades and our commonplace program has been adjusted to satisfy the wants of our clients.
