Ensure top-notch reliability with the right drive for the job

Automated processes are commonplace follow within the food business. Production effectivity just isn’t the only motivation, hygiene additionally plays a key function within the meals business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss how to design a drive to fulfill these necessities and incorporate each these targets.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to make sure that the proper drive is chosen to fulfill the excessive necessities for hygiene in the meals trade, we normally suggest our ADVANCED LINE air vane motors. All their external parts are made from chrome steel and are impervious to normal cleansing agents. The smooth floor of these air motors is straightforward to clean. The drives are so nicely sealed with sturdy long-life radial shaft seals that no air can escape and equally no filth, water or other solutions can penetrate the motor. The motors are even resistant to water penetration from generally used cleansing spray techniques. A wet setting is no concern for this motor. It may even be used underwater as in the case of many stirring purposes. All our ADVANCED LINE stainless steel motors are lubricated with food 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 must be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor need to boast different features for such applications?
Answer: Yes. In many functions, condensation can kind in air provide lines. It is due to this fact advisable that measures are taken to ensure that the motor just isn’t situated at the lowest point within the system and that it could be flushed out with water. Many users take precautionary measures, not solely relating to the structure of the motor of their system, but in addition regarding the utilization of water separators or dryers in front of the drive. If all this isn’t potential, then we advocate a special coating for these parts throughout the motor’s inside that are made from stainless steel. This is because there is a limit to the utilization of chrome steel for heavy obligation, high-speed inner parts. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you might have any examples of where your motors can be utilized within the food industry?
Answer: Stirring dough, moving and slicing sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food trade functions are infinite. I’ll describe a few purposes in additional element, corresponding to 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 velocity 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 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 63 mm.
Another software could be found in grinding mills and conveying systems for grain processing. In this case, the main focus is on dust technology and explosion prevention. All our ADVANCED LINE motors are ATEX licensed for use in probably explosive environments. You will even find our motors used within 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 wood skewer via pieces of meat, onion and pepper. Pressure at 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 benefits does an air motor have over an electric motor in such applications?
Answer: There are many arguments in favour of utilizing an air motor: One of the principle benefits is its excessive energy density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a third of its measurement. This is especially significant when utilizing a handheld device however after all also for robotic techniques where the drive moves with the robotic arm.
Heat also leaves the air motor chilly. In crucial settings, compressed air is an unproblematic supply of vitality – it does not examine to the risks of electricity. The power output from the air motor over wide torque ranges is kind of constant. Air motors can therefore be optimally operated in a large field of fluctuating masses. There is no problem with load being applied on the air motor until standstill, no damages are incurred. This means it is less apt to stalling. After discount of the load, it will run again instantly and any number of successive occasions. Air motor energy can be tailored simply by adjusting the operating pressure. The speed is reduced smoothly by throttling the air volume. Throttling provide air is recommended when torque must also be significantly lowered. Exhaust air throttling should be chosen to minimize back velocity with none severe affect on the torque.
Question: Air motors are often seen to be less environment friendly compared to electric motors. Can you comment on this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one foundation. The efficiency of a drive all the time depends on the circumstances of the application. Let me use this instance to explain: 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 can’t be loaded over a protracted time period with out operating the chance of overheating. Therefore, for this packaging machine, an electrical motor would wish to resist high masses and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). xp2i is a very different story with the air motor: Due to the beneficial torque characteristics of air motors, a lower-powered drive will suffice. You may select 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 underneath gentle load. The power required for this air motor is subsequently only 430W. The power stability of an air motor is seen in a completely totally different mild when you suppose about that the air motor needed for this packaging machine would only require a 3rd of the facility of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on a long time of expertise in the area of air motors. They have a variety of top of the range, globally in style industrial drive solutions. Are the ADVANCED LINE motors a special answer for meals business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our standard program has been adjusted to fulfill the wants of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers profit from long-established dependable drive solutions for the food trade and medical expertise. We are able to offer these motors in a large power range from 20 W to 1.6 kW combined with quite a lot of planetary gears from our personal production with speeds of 7 to 24,000 rpm.
