Automated processes are standard practice in the meals trade. Production efficiency is not the one motivation, hygiene additionally plays a key position in the food business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss the means to design a drive to satisfy these necessities and incorporate each these objectives.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to ensure that the proper drive is chosen to satisfy the excessive requirements for hygiene within the meals industry, we often suggest our ADVANCED LINE air vane motors. All their external components are created from stainless steel and are impervious to normal cleansing agents. The clean surface of those air motors is simple to wash. The drives are so nicely sealed with sturdy long-life radial shaft seals that no air can escape and equally no dirt, water or other solutions can penetrate the motor. The motors are even immune to water penetration from generally used cleansing spray methods. A moist setting isn’t any concern for this motor. It may even be used underwater as in the case of many stirring applications. All our ADVANCED LINE stainless-steel motors are lubricated with food grade USDA-H1 grease and can be operated oil-free. A power discount of approx. 10-20% primarily based on the technical knowledge stated in the product catalog should be taken into account when designing drives for oil-free operation.
Question: Does an air motor must boast other features for such applications?
pressure gauge 10 bar : Yes. In many applications, condensation can form in air supply traces. It is therefore advisable that measures are taken to make sure that the motor is not located at the lowest point in the system and that it could be flushed out with water. Many customers take precautionary measures, not only relating to the layout of the motor of their system, but additionally concerning the use of water separators or dryers in front of the drive. If all this is not possible, then we suggest a special coating for these elements inside the motor’s inside which are made from chrome steel. This is because there’s a restrict to the use of chrome steel for heavy duty, high-speed inside components. pressure gauge 10 bar -called CWL coating supplies 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 belly skewers, mixing sausage meat or unwinding sausage skins, the meals industry functions are endless. I’ll describe a number of purposes in more element, such as 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 on the pace of 700 rpm.
We even have the perfect 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 application could be found in grinding mills and conveying techniques for grain processing. In this case, the major target is on dust generation and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in probably explosive environments. You will even discover our motors used within 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 wood 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 electric motor in such applications?
Answer: There are many arguments in favour of utilizing an air motor: One of the main advantages is its high power density. Depending on the design, an air motor has only a fifth of the mass of an electric motor, or a 3rd of its dimension. This is especially significant when using a handheld system but in fact additionally for robotic methods where the drive strikes with the robot arm.
Heat additionally leaves the air motor chilly. In critical settings, compressed air is an unproblematic source of power – it does not evaluate to the hazards of electricity. The energy output from the air motor over extensive torque ranges is type of constant. Air motors can subsequently be optimally operated in a wide subject of fluctuating loads. There is no downside with load being applied 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’ll run once more instantly and any number of successive times. Air motor energy may be tailored simply by adjusting the working strain. The pace is lowered easily by throttling the air quantity. Throttling provide pressure gauge octa is beneficial when torque must also be considerably lowered. Exhaust air throttling must be chosen to reduce pace with none critical influence on the torque.
Question: Air motors are sometimes seen to be less environment friendly in comparability with electrical motors. Can you comment on this statement?
Answer: Air motors and electric motors cannot be in contrast on a one-to-one basis. The effectivity of a drive at all times depends on the circumstances of the applying. 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 reduced velocity over an extended time frame to secure the packaging tape. Electric motors cannot be loaded over an extended time frame without running the danger of overheating. Therefore, for this packaging machine, an electric motor would want to resist excessive masses and consequently would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally different story with the air motor: Due to the beneficial 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 velocity 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 under mild load. The energy required for this air motor is therefore only 430W. The energy stability of an air motor is seen in a very different gentle when you suppose about 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 a long time of expertise in the area of air motors. They have a variety of high of the range, globally well-liked industrial drive options. Are the ADVANCED LINE motors a particular solution for meals industry applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our normal program has been adjusted to meet the wants of our prospects.
