Automated processes are normal apply within the meals business. Production effectivity is not the only motivation, hygiene additionally plays a key position within the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to satisfy 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 best 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 normal cleansing agents. The easy surface of these air motors is easy to clean. The drives are so nicely sealed with sturdy long-life radial shaft seals that no air can escape and equally no filth, water or other options can penetrate the motor. เกจวัดแรงดันลมคือ are even proof against water penetration from generally used cleaning spray techniques. A moist environment is not any concern for this motor. It can even be used underwater as in the case of many stirring purposes. All our ADVANCED LINE chrome steel motors are lubricated with meals grade USDA-H1 grease and can be operated oil-free. A power discount of approx. 10-20% based mostly on the technical information stated within the product catalog must be taken into account when designing drives for oil-free operation.
Question: Does an air motor need to boast different options for such applications?
Answer: Yes. In many purposes, condensation can form in air supply strains. It is due to this fact advisable that measures are taken to make certain that the motor isn’t located at the lowest point in the system and that it may be flushed out with water. Many customers take precautionary measures, not solely referring to the layout of the motor in their system, but also concerning using water separators or dryers in front of the drive. If all this is not possible, then we advocate a particular coating for those parts inside the motor’s inside that are produced from chrome steel. This is as a end result of there is a limit to the use of stainless-steel for heavy responsibility, high-speed internal elements. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you may have any examples of where your motors can be used within the food industry?
Answer: Stirring dough, shifting and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals business applications are endless. I’ll describe a few functions in more detail, corresponding to the utilization of our ADVANCED LINE air motor in an agitator for the manufacturing of fruit juice. Our 300W air motor drives a propeller stirrer in a magnetic agitator on the speed of 700 rpm.
We also have the ideal drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy within the smallest of areas. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a beginning torque of 585 Nm and has a most diameter of sixty three mm.
Another software may be found in grinding mills and conveying systems for grain processing. In this case, the major target is on dust technology 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 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 through 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 utility.
Question: What advantages 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 excessive energy density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a third of its dimension. This is particularly significant when using a handheld system but after all additionally for robotic techniques the place the drive strikes with the robotic arm.
Heat additionally leaves the air motor chilly. In เกจวัดแรงดันไทวัสดุ , compressed air is an unproblematic supply of power – it doesn’t evaluate to the hazards of electricity. The power output from the air motor over wide torque ranges is nearly constant. Air motors can therefore be optimally operated in a wide area of fluctuating hundreds. There isn’t any downside with load being applied on the air motor till standstill, no damages are incurred. This means it is much less apt to stalling. After reduction of the load, it’ll run again instantly and any variety of successive times. Air motor energy may be tailored simply by adjusting the operating stress. The speed is reduced smoothly by throttling the air quantity. Throttling provide air is really helpful when torque also wants to be considerably lowered. Exhaust air throttling should be chosen to cut back pace with none severe influence 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 can’t be compared on a one-to-one basis. The effectivity of a drive always depends on the circumstances of the appliance. Let me use this example to clarify: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at decreased pace over a protracted time period to safe the packaging tape. Electric motors cannot be loaded over a long time frame without operating the chance of overheating. Therefore, for this packaging machine, an electrical motor would wish to withstand high hundreds and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely completely 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 speed at 450 rpm under light load. The energy required for this air motor is subsequently solely 430W. The power steadiness of an air motor is seen in a completely different light when you assume about that the air motor needed for this packaging machine would solely require a third of the ability of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on many years of experience within the subject of air motors. They have a variety of top of the range, globally well-liked industrial drive solutions. Are the ADVANCED LINE motors a special answer for meals trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our commonplace program has been adjusted to meet the needs of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects benefit from long-established reliable drive solutions for the meals trade and medical know-how.
