Automated processes are commonplace apply in the food trade. Production efficiency isn’t the one motivation, hygiene also performs a key function in the meals trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss how to design a drive to satisfy these requirements and incorporate both these targets.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to guarantee that the proper drive is chosen to fulfill the high necessities for hygiene within the food industry, we often recommend our ADVANCED LINE air vane motors. All their external elements are created from chrome steel and are impervious to regular cleansing brokers. The clean surface of these air motors is easy to clean. The drives are so nicely sealed with durable long-life radial shaft seals that no air can escape and equally no filth, water or different options can penetrate the motor. The motors are even resistant to water penetration from commonly used cleaning spray methods. A wet environment isn’t any concern for this motor. It can even be used underwater as within the case of many stirring applications. All our ADVANCED LINE stainless-steel motors are lubricated with meals grade USDA-H1 grease and may be operated oil-free. A power reduction of approx. 10-20% based mostly 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 have to boast other options for such applications?
Answer: Yes. In many functions, condensation can type in air supply traces. It is subsequently advisable that measures are taken to guarantee that the motor isn’t located at the lowest level within the system and that it can be flushed out with water. Many users take precautionary measures, not solely referring to the structure of the motor in their system, but in addition regarding using water separators or dryers in front of the drive. If all this is not potential, then we recommend a special coating for those elements inside the motor’s interior which are made from stainless-steel. This is because there is a limit to the usage of chrome steel for heavy obligation, high-speed inner parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you might have any examples of where your motors can be used in the food industry?
Answer: Stirring dough, moving and cutting sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals industry functions are endless. I’ll describe a couple of functions in additional element, corresponding 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 700 rpm.
We even have the ideal drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in the smallest of areas. The 900W high-torque motor with a nominal pace of twenty-two rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of sixty three mm.
Another software can be found in grinding mills and conveying systems for grain processing. In this case, the major target is on mud generation and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in doubtlessly explosive environments. You will even find our motors used within the processing of meat, for instance 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 pieces 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 software.
Question: What advantages 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 power density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a third of its size. This is especially vital when using a handheld device but after all additionally for robotic techniques where the drive strikes with the robot arm.
Heat also leaves the air motor cold. In critical settings, compressed air is an unproblematic source of vitality – it doesn’t evaluate to the hazards of electricity. The energy output from the air motor over wide torque ranges is nearly constant. Air motors can due to this fact be optimally operated in a large subject of fluctuating hundreds. There is เกจวัดแรงดันน้ำไทวัสดุ with load being utilized 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’ll run once more immediately and any variety of successive occasions. Air motor power may be adapted simply by adjusting the working stress. The speed is lowered easily by throttling the air quantity. Throttling supply air is beneficial when torque should also be considerably reduced. Exhaust air throttling should be chosen to reduce velocity without any critical affect on the torque.
Question: Air motors are often seen to be less efficient compared to electrical motors. Can you touch upon this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one foundation. The effectivity of a drive all the time is determined by the circumstances of the appliance. 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 velocity over a long time period to safe the packaging tape. Electric motors can’t be loaded over a protracted period of time without operating the chance of overheating. Therefore, for this packaging machine, an electrical motor would want to resist excessive loads and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally totally different story with the air motor: Due to the beneficial torque characteristics of air motors, a lower-powered drive will suffice. You might 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 underneath gentle 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 totally different mild when you consider that the air motor needed for this packaging machine would only require a third of the facility 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 broad range of top of the range, globally well-liked industrial drive options. Are the ADVANCED LINE motors a particular solution for food 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 satisfy the wants of our prospects.
