Automated processes are normal follow in the food industry. Production efficiency just isn’t the one motivation, hygiene also performs a key role 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 requirements and incorporate both these goals.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to make certain that the proper drive is chosen to satisfy the high necessities for hygiene within the food business, we usually suggest our ADVANCED LINE air vane motors. All their external elements are created from stainless-steel and are impervious to regular cleansing brokers. The smooth surface of those air motors is straightforward to scrub. The drives are so nicely sealed with durable 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 commonly used cleansing spray systems. A moist surroundings is not any concern for this motor. เพรสเชอร์เกจ may even be used underwater as in the case of many stirring applications. All our ADVANCED LINE stainless steel motors are lubricated with food grade USDA-H1 grease and can be operated oil-free. A energy discount of approx. 10-20% primarily based on the technical information said within the product catalog must be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor must boast different features for such applications?
Answer: Yes. In many applications, condensation can form in air provide strains. It is due to this fact advisable that measures are taken to ensure that the motor is not positioned on the lowest level within the system and that it can be flushed out with water. Many customers take precautionary measures, not only relating to the format of the motor in their system, but also regarding using water separators or dryers in entrance of the drive. If all this isn’t possible, then we advocate a particular coating for these elements throughout the motor’s interior which are created from stainless-steel. This is as a end result of there is a limit to using stainless-steel for heavy duty, high-speed inside parts. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you have any examples of the place your motors can be used in the food industry?
Answer: Stirring dough, shifting and cutting sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals trade purposes are countless. I’ll describe a couple of functions in additional detail, 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 on the pace of seven hundred rpm.
We even have the perfect drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in 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 application can be present in grinding mills and conveying methods for grain processing. In this case, the major focus is on dust era and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in probably explosive environments. You will even discover 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 wood skewer via items of meat, onion and pepper. Pressure at the skewer is 38 kg and therefore a high-power air motor with compact design is ideally suited to this utility.
Question: What benefits 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 main benefits is its high 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 dimension. This is particularly significant when utilizing a handheld device however in fact also for robotic methods the place the drive strikes with the robot 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 nearly constant. Air motors can due to this fact be optimally operated in a wide subject of fluctuating loads. There is not any drawback with load being utilized 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 may be tailored simply by adjusting the working strain. The pace is decreased smoothly by throttling the air quantity. Throttling provide air is really helpful when torque also needs to be significantly lowered. Exhaust air throttling ought to be chosen to reduce velocity without any serious 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 can’t be in contrast on a one-to-one basis. The efficiency of a drive always is decided by the circumstances of the appliance. Let me use this instance to explain: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at lowered speed over a protracted time period to secure the packaging tape. Electric motors cannot be loaded over a long time period without running the chance of overheating. Therefore, for this packaging machine, an electrical motor would need to withstand excessive loads and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely different story with the air motor: Due to the favourable torque traits of air motors, a lower-powered drive will suffice. You may choose an air motor with a nominal torque of 15 Nm and nominal velocity of 275 rpm. Since the working torque is below that of the nominal torque, the air motor runs close to idle speed at 450 rpm underneath gentle load. The power required for this air motor is due to this fact only 430W. The energy balance of an air motor is seen in a completely different light when you assume about that the air motor wanted for this packaging machine would solely require a 3rd of the ability of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on decades of experience in the field of air motors. They have a variety of prime of the range, globally in style industrial drive options. Are the ADVANCED LINE motors a particular solution for meals 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 fulfill the wants of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers profit from long-established reliable drive solutions for the food business and medical technology.
