Automated processes are commonplace follow within the meals trade. Production efficiency just isn’t the one motivation, hygiene also performs a key position in 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 goals.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to ensure that the proper drive is selected to satisfy the excessive necessities for hygiene within the food trade, we often suggest our ADVANCED LINE air vane motors. All their external parts are created from chrome steel and are impervious to normal cleansing agents. The smooth floor of these 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 dirt, water or different solutions can penetrate the motor. The motors are even resistant to water penetration from generally used cleansing spray methods. A wet surroundings is no 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 may be operated oil-free. A energy discount of approx. 10-20% primarily based on the technical information said in the product catalog ought to be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor need to boast other options for such applications?
Answer: Yes. In many purposes, condensation can type in air supply lines. It is due to this fact advisable that measures are taken to make certain that the motor is not positioned on the lowest point in the system and that it can be flushed out with water. Many customers take precautionary measures, not solely referring to the layout of the motor in their system, but in addition concerning the usage of water separators or dryers in entrance of the drive. If all this isn’t possible, then we suggest a particular coating for those components inside the motor’s interior which are made from stainless-steel. This is because there is a restrict to the use of stainless steel for heavy duty, high-speed inner elements. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you have any examples of the place your motors can be used within 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 business applications are countless. I’ll describe a few applications in more element, such as 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 speed of seven hundred rpm.
We also have the best drive for high-torque requirements 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 speed of 22 rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of sixty three mm.
Another software could be found in grinding mills and conveying systems for grain processing. In this case, the focus is on mud generation and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in potentially 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 wood skewer through items 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 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 primary 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 3rd of its measurement. This is particularly vital when utilizing a handheld gadget but after all additionally for robotic systems where the drive moves with the robot arm.
Heat also leaves the air motor cold. In important settings, compressed air is an unproblematic supply of power – it does not compare to the risks of electricity. The energy output from the air motor over wide torque ranges is almost constant. Air motors can due to this fact be optimally operated in a large field of fluctuating masses. There isn’t any problem with load being applied on the air motor till standstill, no damages are incurred. เกจวัดแรงดันแก๊สco2 means it’s much less apt to stalling. After reduction of the load, it will run once more instantly and any number of successive times. Air motor energy could be adapted simply by adjusting the working strain. The pace is decreased easily by throttling the air volume. Throttling supply air is beneficial when torque should also be significantly reduced. Exhaust air throttling should be chosen to minimize back speed with none critical affect on the torque.
Question: Air motors are sometimes seen to be much less environment friendly in comparability with electrical motors. Can you comment on this statement?
Answer: Air motors and electrical motors cannot be in contrast on a one-to-one foundation. The efficiency of a drive always depends on the conditions of the application. Let me use this instance to clarify: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is utilized at decreased pace over a long time frame to safe the packaging tape. Electric motors can’t be loaded over a long time frame without running the chance of overheating. Therefore, for this packaging machine, an electrical motor would want to withstand excessive masses and in consequence 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 might choose 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 near idle velocity at 450 rpm beneath light load. The energy required for this air motor is therefore solely 430W. The power stability of an air motor is seen in a very completely different mild when you consider that the air motor needed for this packaging machine would only require a third of the power of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on a long time of expertise in the subject 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 particular resolution for food 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 fulfill the needs of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects benefit from long-established reliable drive solutions for the food business and medical technology. We are able to offer these motors in a wide power range from 20 W to 1.6 kW mixed with quite lots of planetary gears from our personal production with speeds of 7 to 24,000 rpm.
