Automated processes are commonplace apply within the meals trade. Production effectivity isn’t the only motivation, hygiene also performs a key function within the food industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss tips on how to design a drive to satisfy these requirements and incorporate each these objectives.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to make sure that the proper drive is chosen to meet the high requirements for hygiene within the food trade, we normally suggest our ADVANCED LINE air vane motors. All their exterior elements are created from stainless-steel and are impervious to normal cleaning brokers. The easy surface of these air motors is easy to wash. The drives are so properly sealed with sturdy long-life radial shaft seals that no air can escape and equally no dust, water or other solutions can penetrate the motor. The motors are even proof against water penetration from commonly used cleaning spray techniques. A wet setting is no concern for this motor. It can even be used underwater as within the case of many stirring functions. All our ADVANCED LINE chrome steel motors are lubricated with food grade USDA-H1 grease and may be operated oil-free. A energy reduction of approx. 10-20% primarily based on the technical information said in the product catalog must be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor have to boast other features for such applications?
Answer: Yes. In many purposes, condensation can type in air supply traces. It is therefore advisable that measures are taken to ensure that the motor is not located on the lowest level in the system and that it might be flushed out with water. Many customers take precautionary measures, not solely referring to the format of the motor in their system, but in addition concerning the use of water separators or dryers in front of the drive. If all this is not attainable, then we suggest a particular coating for those components inside the motor’s interior which are made from chrome steel. This is as a end result of there is a limit to the use of stainless-steel for heavy duty, high-speed inside components. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you have any examples of where your motors can be utilized within the meals industry?
Answer: Stirring dough, moving and cutting sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food trade purposes are endless. I’ll describe a few functions in additional element, corresponding to the usage 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 at the velocity of 700 rpm.
We also have the perfect drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power in the smallest of areas. The 900W high-torque motor with a nominal velocity of twenty-two rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of sixty three mm.
Another utility can be found in grinding mills and conveying systems for grain processing. In this case, the focus is on mud era and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in probably 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 picket skewer via pieces of meat, onion and pepper. Pressure on 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 principle benefits is its excessive energy density. Depending on the design, an air motor has solely a fifth of the mass of an electric motor, or a third of its measurement. This is particularly important when using a handheld device however after all additionally for robotic methods the place the drive strikes with the robotic arm.
Heat also leaves the air motor chilly. In important settings, compressed air is an unproblematic source of power – it doesn’t evaluate to the dangers of electricity. The energy output from the air motor over extensive torque ranges is nearly constant. Air motors can subsequently be optimally operated in a wide area of fluctuating loads. There is not any problem with load being applied on the air motor until standstill, no damages are incurred. This means it is much less apt to stalling. After reduction of the load, it’s going to run again immediately and any number of successive occasions. Air motor energy could be tailored just by adjusting the operating pressure. The pace is lowered smoothly by throttling the air volume. Throttling provide air is recommended when torque also wants to be significantly reduced. Exhaust air throttling must be chosen to scale back velocity without any critical affect on the torque.
Question: Air motors are often seen to be much less environment friendly in comparison with electrical 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 effectivity of a drive at all times is dependent upon the situations of the appliance. Let me use this example to elucidate: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at reduced speed over an extended period of time to secure the packaging tape. Electric motors cannot be loaded over a protracted time period with out running the chance of overheating. Therefore, for this packaging machine, an electric motor would wish to face up to excessive masses and as a result would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a very 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 pace of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs close to idle velocity at 450 rpm beneath mild load. The energy required for this air motor is therefore only 430W. The vitality stability of an air motor is seen in a completely totally different gentle when you consider that the air motor needed for this packaging machine would only require a third of the facility of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on decades of experience in the field of air motors. They have a extensive range of high of the range, globally in style industrial drive options. Are the ADVANCED LINE motors a special answer for food business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our normal program has been adjusted to satisfy the needs of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects benefit from long-established reliable drive options for the food industry and medical expertise.
