Automated processes are commonplace apply within the food trade. Production effectivity is not the one motivation, hygiene additionally performs a key role within the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate the means to design a drive to fulfill these requirements and incorporate each these goals.
Question: How are high requirements of hygiene met by DEPRAG?
Answer: In order to make certain that the right drive is selected to satisfy the excessive requirements for hygiene within the meals trade, we normally recommend our ADVANCED LINE air vane motors. All their external elements are produced from stainless-steel and are impervious to normal cleansing agents. The smooth floor of those air motors is easy to wash. The drives are so nicely 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 generally used cleansing spray systems. A moist setting isn’t any concern for this motor. It may even be used underwater as in the case of many stirring functions. 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 on the technical knowledge acknowledged in the product catalog ought to be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor must boast different options for such applications?
Answer: Yes. In many functions, condensation can form in air supply traces. It is due to this fact advisable that measures are taken to make sure that the motor isn’t located on the lowest level within the system and that it can be flushed out with water. Many customers take precautionary measures, not only regarding the structure of the motor of their system, but additionally regarding the use of water separators or dryers in entrance of the drive. If all this isn’t possible, then we suggest a particular coating for these parts inside the motor’s inside which are made from chrome steel. This is as a result of there’s a restrict to the utilization of stainless steel for heavy responsibility, high-speed inner elements. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you might have any examples of where your motors can be utilized within the meals industry?
Answer: Stirring dough, moving and slicing sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food trade purposes are infinite. I’ll describe a quantity of purposes in more element, such as the use 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 speed of seven hundred rpm.
We even have the best drive for high-torque necessities 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 velocity of 22 rpm overcomes a starting torque of 585 Nm and has a most diameter of sixty three mm.
Another software can be found in grinding mills and conveying techniques for grain processing. In this case, the main target is on mud era and explosion prevention. All our ADVANCED LINE motors are ATEX licensed for use in potentially explosive environments. You will even find our motors used in 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 picket skewer via items 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 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 main advantages is its high 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 dimension. This is especially important when using a handheld system however in fact also for robotic methods where the drive strikes with the robot arm.
Heat additionally leaves the air motor cold. In important settings, compressed air is an unproblematic supply of power – it does not compare to the hazards of electrical energy. The energy output from the air motor over wide torque ranges is sort of constant. Air motors can due to this fact be optimally operated in a wide subject of fluctuating loads. There is no problem with load being utilized on the air motor until standstill, no damages are incurred. This means it’s much less apt to stalling. After reduction of the load, it will run once more instantly and any number of successive instances. Air motor energy could be adapted simply by adjusting the working pressure. The speed is lowered smoothly by throttling the air volume. Throttling supply air is recommended when torque should also be considerably reduced. Exhaust air throttling must be chosen to scale back velocity with none severe affect on the torque.
Question: Air motors are sometimes seen to be less efficient compared to electric motors. Can you comment on this statement?
Answer: Air motors and electrical motors cannot be in contrast on a one-to-one foundation. The effectivity of a drive all the time is dependent upon the conditions 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 pace over an extended period of time to safe the packaging tape. Electric motors can’t be loaded over a long time period with out running the danger of overheating. Therefore, for this packaging machine, an electrical motor would want to withstand high loads and in consequence would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely 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 velocity of 275 rpm. Since the working torque is beneath that of the nominal torque, the air motor runs close to idle pace at 450 rpm under mild load. The energy required for this air motor is due to this fact only 430W. The vitality balance of an air motor is seen in a very totally different gentle when you suppose about that the air motor needed for this packaging machine would solely require a 3rd of the ability of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on many years of experience in the field of air motors. They have a variety of high quality, globally popular industrial drive options. Are the ADVANCED LINE motors a particular resolution for food business 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 meet the needs of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients profit from long-established reliable drive options for the meals industry and medical technology.
