Automated processes are commonplace practice within the meals industry. Production efficiency isn’t the only motivation, hygiene also performs a key function in the food business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate tips on how to design a drive to satisfy these requirements and incorporate both these goals.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to guarantee that the best drive is selected to fulfill the excessive requirements for hygiene within the food industry, we normally recommend our ADVANCED LINE air vane motors. All their external parts are made from chrome steel and are impervious to normal cleaning agents. The easy floor of those air motors is straightforward to wash. The drives are so nicely sealed with durable long-life radial shaft seals that no air can escape and equally no dirt, water or different options can penetrate the motor. The motors are even resistant to water penetration from generally used cleaning spray techniques. A wet surroundings isn’t any concern for this motor. It can even be used underwater as in the case of many stirring applications. All our ADVANCED LINE chrome steel motors are lubricated with meals grade USDA-H1 grease and may be operated oil-free. A power reduction of approx. 10-20% primarily based on the technical knowledge 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 other options for such applications?
Answer: Yes. In many applications, condensation can kind in air supply strains. It is therefore advisable that measures are taken to make sure that the motor isn’t positioned on the lowest point in the system and that it may be flushed out with water. Many users take precautionary measures, not solely regarding the format of the motor of their system, but in addition concerning the usage of water separators or dryers in front of the drive. If all this is not potential, then we recommend a special coating for these elements throughout the motor’s inside that are created from chrome steel. This is because there’s a limit to using stainless-steel for heavy duty, high-speed inside components. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you may have any examples of the place your motors can be utilized within the meals industry?
Answer: Stirring dough, shifting and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food trade functions are infinite. I’ll describe a couple of purposes in more element, corresponding to the utilization of our ADVANCED LINE air motor in an agitator for the manufacturing of fruit juice. pressure gauge 10 bar drives a propeller stirrer in a magnetic agitator on 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 power in the smallest of spaces. The 900W high-torque motor with a nominal pace of twenty-two rpm overcomes a starting torque of 585 Nm and has a maximum diameter of sixty three mm.
Another software may be found in grinding mills and conveying methods for grain processing. In this case, the main target is on dust technology and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in doubtlessly 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 picket skewer via pieces of meat, onion and pepper. Pressure on the skewer is 38 kg and therefore 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 using an air motor: One of the primary benefits is its high energy density. Depending on pressure gauge 10 bar , an air motor has solely a fifth of the mass of an electric motor, or a third of its dimension. This is particularly significant when utilizing a handheld system however of course also for robotic techniques the place the drive moves with the robot arm.
Heat also leaves the air motor cold. In important settings, compressed air is an unproblematic supply of vitality – it doesn’t compare to the dangers of electricity. The energy output from the air motor over extensive torque ranges is nearly fixed. Air motors can therefore be optimally operated in a wide area of fluctuating masses. There isn’t any problem with load being applied on the air motor until standstill, no damages are incurred. This means it’s much less apt to stalling. After discount of the load, it’s going to run again instantly and any number of successive times. Air motor energy could be tailored simply by adjusting the working stress. The pace is reduced easily by throttling the air volume. Throttling supply air is really helpful when torque should also be considerably lowered. Exhaust air throttling must be chosen to scale back speed with none severe influence on the torque.
Question: Air motors are often seen to be much less efficient in comparison with electric motors. Can you comment on this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one basis. The efficiency of a drive always depends on the situations of the applying. Let me use this instance to elucidate: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at decreased speed over an extended time frame to secure the packaging tape. Electric motors cannot be loaded over a protracted period of time without running the risk of overheating. Therefore, for this packaging machine, an electric motor would need to withstand high hundreds and consequently would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very different story with the air motor: Due to the beneficial torque traits of air motors, a lower-powered drive will suffice. You could 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 beneath light load. The energy required for this air motor is therefore solely 430W. The power steadiness of an air motor is seen in a completely totally different mild when you suppose about that the air motor wanted for this packaging machine would solely require a third of the power of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on a long time of experience within the area of air motors. They have a variety of high quality, globally in style industrial drive options. Are the ADVANCED LINE motors a particular answer for food trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our commonplace program has been adjusted to meet the wants of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers benefit from long-established dependable drive solutions for the food business and medical expertise.
