Automated processes are normal follow within the meals industry. Production effectivity isn’t the only motivation, hygiene also performs a key function within 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 fulfill these necessities and incorporate both these targets.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to ensure that the right drive is selected to satisfy the excessive requirements for hygiene within the meals trade, we often advocate our ADVANCED LINE air vane motors. All their external parts are produced from chrome steel and are impervious to regular cleansing agents. The smooth floor of these air motors is simple to scrub. The drives are so well sealed with durable 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 methods. A moist setting is no concern for this motor. It may 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 energy discount of approx. 10-20% primarily based on the technical knowledge acknowledged within the product catalog must be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor must boast other options for such applications?
Answer: Yes. In many functions, condensation can kind in air provide strains. It is due to this fact advisable that measures are taken to make certain that the motor just isn’t located at the lowest level in the system and that it can be flushed out with water. Many users take precautionary measures, not only regarding the format of the motor of their system, but in addition concerning the use of water separators or dryers in front of the drive. If all this is not potential, then we recommend a particular coating for those parts inside the motor’s inside which are made from chrome steel. This is as a result of there is a limit to the use of stainless steel for heavy obligation, high-speed internal parts. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you’ve any examples of the place your motors can be used in the meals industry?
Answer: Stirring dough, transferring and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food industry applications are countless. I’ll describe a couple of purposes in additional element, such as the utilization 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 on the pace of seven-hundred rpm.
We also have the ideal drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power within the smallest of areas. The 900W high-torque motor with a nominal velocity of 22 rpm overcomes a starting torque of 585 Nm and has a most diameter of 63 mm.
Another software may be present in grinding mills and conveying methods for grain processing. In this case, the focus is on mud technology and explosion prevention. All our ADVANCED LINE motors are ATEX licensed for use in doubtlessly explosive environments. You will even discover 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 picket skewer through 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 software.
Question: What benefits 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 principle benefits is its high power density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a 3rd of its dimension. This is especially important when utilizing a handheld gadget but after all also for robotic techniques the place the drive moves with the robot arm.
Heat also leaves the air motor cold. In crucial settings, compressed air is an unproblematic supply of energy – it does not compare to the risks of electrical energy. The power output from the air motor over extensive torque ranges is nearly constant. Air motors can subsequently be optimally operated in a large subject of fluctuating hundreds. There is no problem with load being utilized on the air motor until standstill, no damages are incurred. This means it is much less apt to stalling. After discount of the load, it will run once more immediately and any number of successive instances. Air motor energy could be adapted simply by adjusting the operating strain. The pace is reduced smoothly by throttling the air volume. Throttling supply air is recommended when torque also needs to be significantly lowered. Exhaust air throttling should be chosen to reduce pace without any severe affect on the torque.
Question: Air motors are sometimes seen to be much less environment friendly compared to electrical motors. Can you touch upon this statement?
Answer: Air motors and electrical motors cannot be compared on a one-to-one foundation. The efficiency of a drive always is determined by the conditions of the application. 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 lowered velocity over a long time period to secure the packaging tape. Electric motors cannot be loaded over a long period of time without working the chance of overheating. Therefore, for this packaging machine, an electric motor would wish to withstand high loads and as a result 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 favourable 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 speed of 275 rpm. Since Effortless 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 therefore solely 430W. The energy stability of an air motor is seen in a totally completely different gentle when you consider that the air motor wanted 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 experience in the area of air motors. They have a broad range of high quality, globally well-liked industrial drive options. Are the ADVANCED LINE motors a special solution for food industry applications?
