Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a fat powder production system. Background Technology

[0002] The proper addition of oils and fats to livestock and poultry feed has several important implications. Firstly, it can significantly improve the energy level of livestock and poultry feed. Livestock and poultry require sufficient energy to maintain normal life activities at various physiological stages, including growth, development, and reproduction. Oils and fats are rich in energy, and adding them to feed can effectively meet the energy needs of animals at different growth stages. Secondly, oils and fats can also provide animals with essential fatty acids. Essential fatty acids are important nutrients that animals cannot synthesize themselves and must obtain from food; they participate in various physiological processes within the animal body.

[0003] However, oils have a certain viscosity and are prone to oxidative rancidity. Therefore, oils are processed into fat powder. Furthermore, fat powder greatly improves the convenience of adding oils to compound feeds and during transportation. Compared to liquid oils, fat powder is a solid powder, making it easier to weigh, mix, and store. It is also less prone to leakage during transportation, reducing transportation costs and risks.

[0004] However, the mainstream fat powder on the market is mainly adsorbent fat powder, which has relatively large oil particles. Larger particles require more time and digestive enzymes to break down during animal digestion, potentially affecting the animal's digestion and absorption efficiency, leading to some fat not being fully utilized and resulting in nutrient waste. There are also certain shortcomings in the fat powder production process. Freshly formed fat powder is produced at a high temperature, and prolonged exposure to high temperatures has a significant negative impact on its quality. High temperatures accelerate the oxidation reaction of oils, making fat powder more prone to oxidative rancidity. Once fat powder becomes oxidatively rancid, not only will its nutrients be significantly lost, but it will also produce toxic and harmful substances, seriously affecting product quality and consequently adversely impacting the health and growth performance of livestock and poultry. Utility Model Content

[0005] The purpose of this invention is to provide a fat powder production system that reduces fat powder particle size, improves fat coating effect, improves fat powder quality, increases fat utilization rate, and saves resources; moreover, it can avoid the impact of high temperature on fat powder.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Fat powder production system, including:

[0008] The oil mixing unit includes an oil mixing tank and several oil storage tanks. The top of the oil mixing tank is provided with a first micro-jet nozzle, and the several oil storage tanks are all connected to the first micro-jet nozzle through their respective first delivery pipes.

[0009] The batching unit includes a wall material batching tank and a stirring mechanism, wherein the stirring mechanism is disposed inside the wall material batching tank;

[0010] The homogenization unit includes a homogenization tower, the top of which is provided with a second micro-jet nozzle, the oil mixing tank is connected to the second micro-jet nozzle through a second conveying pipe, and the wall material mixing tank is connected to the second micro-jet nozzle through a third conveying pipe.

[0011] The powder-making unit includes a spray tower, an air inlet pipe, and a refrigeration component with an elliptical heat exchange surface. The refrigeration component is located at the bottom of the spray tower, and an atomizing nozzle is located at the top of the spray tower. One end of the air inlet pipe is connected to an air compressor, and the other end of the air inlet pipe is connected to the atomizing nozzle. The homogenizing tower is connected to the atomizing nozzle through a fourth conveying pipe.

[0012] As an optional solution for the fat powder production system, the powder-making unit further includes:

[0013] Cyclone separators are connected to the lower ends of both sides of the spray tower.

[0014] As an optional solution for the fat powder production system, an air dryer is installed on the air intake pipe.

[0015] As an optional solution for the fat powder production system, the first conveying pipeline is equipped with a first switching valve, a first pump body, and a first metering device.

[0016] As an optional solution for the fat powder production system, the second conveying pipeline is equipped with a second switching valve, a second pump body, and a second metering device.

[0017] As an optional solution for the fat powder production system, the third conveying pipeline is equipped with a third switching valve, a third pump body, and a third metering device.

[0018] As an optional solution for the fat powder production system, the fourth conveying pipeline is equipped with a fourth switching valve and a fourth pump body.

[0019] As an optional solution for the fat powder production system, the homogenization unit further includes:

[0020] A multi-stage centrifugal pump is provided, wherein the bottom of the homogenizing tower is connected to the inlet of the multi-stage centrifugal pump through a first circulation pipe, and the outlet of the multi-stage centrifugal pump is connected to the top of the homogenizing tower through a second circulation pipe.

[0021] As an alternative to the fat powder production system, a fifth switching valve and a flow controller are installed on the first circulation pipeline.

[0022] As an optional solution for the fat powder production system, the stirring mechanism includes a stirring shaft and stirring blades. The stirring shaft is rotatably connected to the top of the wall material mixing tank, and a plurality of stirring blades are circumferentially spaced on the stirring shaft.

[0023] The beneficial effects of this utility model are:

[0024] The fat powder production system provided by this utility model connects multiple oil storage tanks to the first micro-jet nozzles of the oil mixing tank via their respective first conveying pipes. The required wall material is added to the wall material mixing tank and mixed by a stirring mechanism. The wall material in the mixing tank and the mixed oil in the oil mixing tank are sprayed through a second micro-jet nozzle, converging and fusing in a homogenizing tower to form a mixture. Different oils can be passed through the first micro-jet nozzle, while oil and wall material solution are passed through the second micro-jet nozzle, enabling rapid mixing and improving mixing efficiency. Furthermore, the material particles are smaller after passing through the micro-jet nozzles, effectively improving the homogenization effect. Then, the mixture and high-pressure gas from the inlet pipe are simultaneously conveyed to the atomizing nozzles of the spray tower. After atomization, the mixture effectively disperses the material into micro-droplets. Under gravity, these micro-droplets fall onto the elliptical heat exchange surface of the refrigeration component, where they are rapidly cooled into solid powder. Utilizing low-temperature cold spray technology, the formed solid powder slides along the elliptical heat exchange surface of the refrigeration component to the bottom of the spray tower. Not only are the fat powder particles produced smaller, which can be fully absorbed by animals, improving fat utilization and saving resources; but the use of low-temperature cold spraying technology also makes the fat powder particles distinct, avoiding high temperatures that could cause fat deterioration and affect the quality of the fat powder.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] To achieve integrated production of fat powder, avoid the impact of high temperatures on fat powder, and improve production efficiency; moreover, the produced fat powder particles are smaller, which can be fully absorbed by animals, improving fat utilization and saving resources, this embodiment provides a fat powder production system, which is described below in conjunction with... Figure 1 The specific content of this embodiment will be described in detail.

[0038] The fat powder production system in this embodiment includes an oil blending unit 1, a batching unit 2, a homogenization unit 3, and a powdering unit 4. The oil blending unit 1, as the starting point of the entire production system, plays a crucial role in precisely blending the oils. The oil blending unit 1 includes an oil blending tank 12 and several oil storage tanks 11. A first micro-jet nozzle 121 is installed on the top of the oil blending tank 12, and the several oil storage tanks 11 are all connected to the first micro-jet nozzle 121 through their respective first conveying pipes 13. This arrangement allows different types and properties of oils to be simultaneously gathered at the first micro-jet nozzle 121 according to production needs and in precise proportions. Under the high-speed jetting action of the first micro-jet nozzle 121, various oils achieve efficient mixing instantly, resulting in not only fast mixing speed but also extremely high mixing uniformity. This precise oil blending method can meet the diverse needs of different livestock breeds and different growth stages for oil composition, laying a solid foundation for the production of high-quality fat powder. The oil mixing is carried out by the first micro-jet nozzle 121, which greatly improves the efficiency and uniformity of oil mixing and avoids problems such as insufficient mixing and uneven local concentration that may occur in traditional mixing methods, thus ensuring the stability and consistency of oil components in each batch of fat powder produced.

[0039] The batching unit 2 is primarily responsible for the preparation and mixing of wall material materials. The batching unit 2 includes a wall material batching tank 21 and a stirring mechanism 22, which is located inside the batching tank 21. During production, the required wall material materials, such as carbohydrates and proteins with good coating properties and stability, are added to the batching tank 21 according to a precise formula ratio. Subsequently, the stirring mechanism 22 is activated, and it thoroughly mixes the wall material materials at an appropriate speed and stirring method. This stirring process not only ensures the uniform dispersion of various wall material materials but also promotes their interaction, forming a uniform and stable wall material solution. A uniform wall material solution is crucial for subsequent mixing with oils and the formation of fat powder. It ensures that the wall material uniformly coats the surface of oil particles, forming a stable structure, thereby improving the stability and shelf life of the fat powder. Simultaneously, a uniform wall material solution also provides the fat powder with good physical properties, such as suitable particle size and flowability, facilitating subsequent production, processing, storage, and transportation.

[0040] The homogenization unit 3 is a crucial link in the entire production system for achieving deep integration of grease and wall material. The homogenization unit 3 includes a homogenization tower 31, with a second micro-jet nozzle 311 at its top. The oil mixing tank 12 is connected to the second micro-jet nozzle 311 via a second conveying pipe 14, and the wall material mixing tank 21 is connected to the second micro-jet nozzle 311 via a third conveying pipe 23. During production, the uniformly mixed grease in the oil mixing tank 12 and the wall material solution in the wall material mixing tank 21 are simultaneously conveyed to the second micro-jet nozzle 311 through their respective conveying pipes. Under the high-speed jetting action of the second micro-jet nozzle 311, the grease and wall material solution instantly impact and mix at extremely high speeds, rapidly converging and deeply integrating within the homogenization tower 31 to form a homogeneous mixture. This method of mixing using micro-jet nozzles, on the one hand, further refines the material particles under high-speed shearing and impact after passing through the micro-jet nozzles, effectively improving the homogenization effect and allowing the grease and wall material to bond more tightly, forming a more stable structure. On the other hand, this rapid mixing method significantly shortens mixing time, improves production efficiency, and can meet the needs of large-scale industrial production. The mixture processed by homogenization unit 3 has finer and more uniform particles and higher stability, providing a strong guarantee for the subsequent formation of high-quality fat powder.

[0041] The powder preparation unit 4 is the final process in the fat powder production system, determining the final form and quality of the fat powder. The powder preparation unit 4 includes a spray tower 41, an air inlet pipe 42, and a refrigeration assembly 43 with an elliptical heat exchange surface 431. The refrigeration assembly 43 is located at the bottom of the spray tower 41, and an atomizing nozzle 411 is located at the top of the spray tower 41. One end of the air inlet pipe 42 is connected to an air compressor 421, and the other end is connected to the atomizing nozzle 411. The homogenizing tower 31 is connected to the atomizing nozzle 411 via a fourth conveying pipe 32. During production, the mixture in the homogenizing tower 31 and the high-pressure gas in the air inlet pipe 42 are simultaneously conveyed to the atomizing nozzle 411 of the spray tower 41. Under the action of the high-pressure gas, the mixture is effectively dispersed into a large number of tiny droplets after passing through the atomizing nozzle 411. These micro-droplets fall freely under gravity and land on the elliptical heat exchange surface 431 of the refrigeration assembly 43. The elliptical heat exchange surface 431 possesses a unique geometry and excellent heat exchange performance, enabling it to rapidly absorb and dissipate the heat from microdroplets, quickly cooling them into solid powder within a very short time. This improves fat coating and enhances fat powder quality. Utilizing this low-temperature cold spray technology, firstly, because the microdroplets are less affected by external interference during cooling, the resulting solid powder particles are smaller. These smaller fat particles are more easily digested and absorbed by animals, significantly improving fat utilization and conserving feed resources. Secondly, the low-temperature cold spray technology prevents fat powder particles from sticking together, resulting in distinct particles with good flowability and dispersibility, facilitating uniform addition and use in feed. Furthermore, the low-temperature environment effectively inhibits oxidative rancidity of the fat powder during production, extending its shelf life and ensuring product quality stability.

[0042] For example, the first micro-jet nozzle 121 and the second micro-jet nozzle 311 employ the same structure, which can be a Y-type homogenizing valve. The internal channels of the Y-type homogenizing valve are arranged in a Y-shape. This special structure allows the fluid to generate strong shear forces and turbulence as it passes through. When grease or mixtures pass through the Y-type homogenizing valve, the material is subjected to multi-directional compression, shearing, and impact under the action of the narrow channels and special angles within the valve. This strong force effectively breaks down large particles in the material into finer particles, greatly improving the homogenization of the material.

[0043] Furthermore, the powder-making unit 4 also includes cyclone separators 44, which are connected to the lower ends of both sides of the spray tower 41. The product is collected from the discharge port at the lower end of the cyclone separator 44. Specifically, cyclone separators 44 are connected to the lower ends of both sides of the spray tower 41. The cyclone separator 44 is a high-efficiency device that uses centrifugal force for gas-solid separation. When the airflow containing fat powder particles enters the cyclone separator 44 from the spray tower 41, due to the special conical structure and rotating airflow design inside the cyclone separator 44, the airflow will rotate at high speed inside the cyclone separator 44. During the rotation, the fat powder particles are subjected to centrifugal force and move downwards along the wall of the cyclone separator 44, eventually settling at the bottom of the cyclone separator 44. The clean gas is discharged from the exhaust port at the top of the cyclone separator 44. In this way, the cyclone separator 44 can efficiently separate fat powder from the airflow. Adding a cyclone separator 44 can significantly improve the collection efficiency and purity of fat powder. It avoids problems such as agglomeration and adhesion caused by prolonged residence of fat powder in the airflow, ensuring that the collected fat powder particles are evenly dispersed and of stable quality. At the same time, the use of the cyclone separator 44 reduces the loss of fat powder during production, improves the utilization rate of raw materials, and lowers production costs. The product is finally collected from the discharge port at the lower end of the cyclone separator 44. This collection method is convenient and quick, and facilitates continuous and automated production.

[0044] Furthermore, an air dryer 422 is installed on the air intake pipe 42. The air dryer 422 is a device capable of removing moisture from the air. It reduces the moisture content of the air to an extremely low level through specific adsorption, condensation, or membrane separation technologies. During the production of fat powder, if the air in the air intake pipe 42 contains a large amount of moisture, it will have several adverse effects on the formation of the fat powder. For example, moisture may hydrolyze with the oil, leading to a decline in the quality of the oil; moisture may also form a water film on the surface of the fat powder, affecting its drying and setting, making the fat powder particles prone to adhesion, and reducing the product's flowability and dispersibility. By adding the air dryer 422, the negative impact of moisture in the air on the formation of fat powder can be effectively eliminated. After the dry air enters the spray tower 41, it ensures that the fat powder is not disturbed by moisture during the cooling and setting process, keeping the fat powder particles in a dry and loose state, improving the quality and stability of the fat powder. At the same time, the dry air also helps to improve the atomization effect, allowing the mixture to be more evenly dispersed into microdroplets, further optimizing the particle size and distribution of the fat powder.

[0045] In order to achieve precise control and efficient management of the material conveying process in the fat powder production process, a meticulous and scientific layout was carried out in the system pipeline design.

[0046] Specifically, a first switching valve 131, a first pump body 132, and a first metering device 133 are installed on the first conveying pipeline 13. The first switching valve 131 can quickly open or close the pipeline passage according to production instructions, realizing flexible start and stop control of the oil conveying operation from the storage tank 11 to the distribution tank 12. When producing different types of fat powder or adjusting the production formula, the first switching valve 131 can accurately control when to start conveying which type of oil, avoiding unnecessary material waste and cross-contamination. The first pump body 132 acts as the power engine for oil conveying, providing stable and adjustable pressure to ensure that the oil in the storage tank 11 is smoothly conveyed to the distribution tank 12 through the first conveying pipeline 13 at a suitable flow rate and volume. According to the viscosity of different oils and the conveying distance, the operating parameters of the first pump body 132 can be flexibly adjusted to ensure the stability and efficiency of oil conveying. The first metering device 133 can measure the amount of oil passing through the first conveying pipeline 13 in real time and accurately, and feed the data back to the production control system. Through the first metering device 133, production personnel can accurately control the delivery volume of each type of oil, ensuring that the various oils in the oil mixing tank 12 are mixed according to the predetermined formula ratio, providing key data support for the production of stable quality fat powder.

[0047] Specifically, a second switching valve 141, a second pump body 142, and a second metering device 143 are also installed on the second conveying pipeline 14. The second switching valve 141 controls the on / off flow of mixed oil from the oil mixing tank 12 to the homogenizing tower 31. During production, when it is necessary to adjust the timing of mixed oil delivery or perform equipment maintenance, the second switching valve 141 can quickly cut off or connect the pipeline to ensure the continuity and safety of production. The second pump body 142 provides power for the delivery of mixed oil from the oil mixing tank 12 to the homogenizing tower 31, ensuring that the mixed oil enters the homogenizing tower 31 with a stable pressure and flow rate, and is fully mixed with the wall material. The second metering device 143 accurately measures the delivery volume of mixed oil, enabling production personnel to monitor the usage of mixed oil in real time and adjust the delivery volume in a timely manner according to production needs, ensuring the accuracy of the proportion of the mixed materials in the homogenizing tower 31, thereby improving the quality consistency of the fat powder.

[0048] Specifically, a third switching valve 231, a third pump body 232, and a third metering device 233 are installed on the third conveying pipeline 23. The third switching valve 231 controls the flow of wall material solution from the wall material mixing tank 21 to the homogenizing tower 31. During the production preparation stage or when the wall material formula needs to be changed, the third switching valve 231 can conveniently control the start and stop of the wall material solution delivery. The third pump body 232 provides power for the delivery of the wall material solution, ensuring that the wall material solution can reach the homogenizing tower 31 smoothly and quickly and blend with the mixed oil. The third metering device 233 accurately measures the delivery volume of the wall material solution, providing production personnel with accurate wall material usage data, ensuring that the ratio of wall material to oil meets production requirements, and thus producing high-performance fat powder.

[0049] Specifically, a fourth switching valve 321 and a fourth pump body 322 are installed on the fourth conveying pipeline 32. The fourth switching valve 321 controls the on / off flow of the mixture from the homogenizing tower 31 to the spray tower 41. When the spray tower 41 is undergoing equipment debugging, maintenance, or when the conveying time is adjusted according to the production schedule, the fourth switching valve 321 can be operated flexibly to ensure the smooth operation of the production process. The fourth pump body 322 provides power for the conveying of the mixture from the homogenizing tower 31 to the spray tower 41, ensuring that the mixture can enter the spray tower 41 at a stable flow rate for atomization, laying the foundation for the subsequent formation of high-quality fat powder.

[0050] These on / off valves, pumps, and metering devices installed on each conveying pipeline form an organic control system. They work together in concert to achieve precise control of the material conveying process during fat powder production. The flexible operation of the on / off valves allows for timely adjustments to the material conveying status according to production needs; the stable power provided by the pumps ensures the continuity and efficiency of material conveying; and the accurate data provided by the metering devices provides strong support for production process optimization and quality control. This precise control method not only improves the stability and reliability of fat powder production and reduces fluctuations and errors in the production process, but also enables rapid adjustment of production parameters according to different production requirements, producing a variety of high-quality fat powder products.

[0051] Furthermore, to significantly improve the homogenization of the mixture during the fat powder production process and ensure the final product has a highly uniform and stable quality, the homogenization unit 3 also includes a multi-stage centrifugal pump 33. In terms of system layout, a carefully designed circulation path is employed. Specifically, the bottom of the homogenizing tower 31 is connected to the inlet of the multi-stage centrifugal pump 33 via a first circulation pipe 34, while the outlet of the multi-stage centrifugal pump 33 is connected to the top of the homogenizing tower 31 via a second circulation pipe 35. The mixture within the homogenizing tower 31 is circulated into the multi-stage centrifugal pump 33. The multi-stage centrifugal pump 33, with its unique working principle, plays a crucial role in the mixture circulation process. It has multiple impellers inside. When the mixture enters the multi-stage centrifugal pump 33 from the bottom of the homogenizing tower 31 through the first circulation pipe 34, it gains significant kinetic energy under the action of the high-speed rotating impellers. Each impeller stage accelerates and pressurizes the mixture, causing it to undergo multiple energy conversions and velocity increases within the pump. This multi-stage acceleration and pressurization process generates extremely strong shear forces and turbulence. When the mixture returns from the outlet of the multistage centrifugal pump 33 to the top of the homogenizing tower 31 via the second circulation pipe 35, the large particles, uneven oil clumps, and wall material aggregates inside will be further broken down and dispersed under strong shear force and turbulence. This method of circulating the mixture back into the multistage centrifugal pump 33 greatly improves the homogenization of the mixture, allowing the oil and wall material to be more fully and uniformly integrated, providing a solid guarantee for the subsequent powdering unit 4 to produce uniformly sized and stable fat powder.

[0052] Furthermore, to achieve precise control and optimized adjustment of the mixture circulation process, a fifth switching valve 341 and a flow controller 342 are installed on the first circulation pipeline 34. The fifth switching valve 341 acts as a control switch, capable of rapidly opening or closing the first circulation pipeline 34 according to production needs, thereby controlling whether the mixture enters the multi-stage centrifugal pump 33 for circulation homogenization. When equipment maintenance, repair, or when the circulation homogenization operation needs to be paused according to production conditions, the fifth switching valve 341 can promptly cut off the pipeline passage, ensuring the safety of the equipment and the production process. The flow controller 342 precisely regulates the flow rate of the mixture passing through the first circulation pipeline 34. Through the flow controller 342, the amount of mixture entering the multi-stage centrifugal pump 33 can be flexibly adjusted according to the actual situation of the mixture in the homogenizing tower 31 and the required degree of homogenization. When the mixture contains a large amount of large particles and has poor homogenization, the flow rate can be appropriately increased to allow more mixture to participate in circulation homogenization and accelerate the homogenization process; when the mixture has reached a good homogenization state, the flow rate can be reduced to avoid excessive circulation that would lead to energy waste and equipment damage. The synergistic effect of the fifth switching valve 341 and the flow controller 342 makes the mixture circulation homogenization process more flexible, efficient, and controllable. This not only ensures that the mixture is homogenized in its optimal state, improving the quality stability of the fat powder, but also allows for dynamic adjustments based on actual production conditions, optimizing the production process and reducing production costs.

[0053] For example, the stirring mechanism 22 includes a stirring shaft and stirring blades. The stirring shaft is rotatably connected to the top of the wall material mixing tank 21, and several stirring blades are circumferentially spaced on the stirring shaft. In the wall material mixing stage of fat powder production, to ensure that the various components of the wall material can be fully and uniformly mixed, thereby ensuring the quality stability of the final fat powder product, the stirring mechanism 22 mainly consists of two key components: the stirring shaft and the stirring blades. As the core support and transmission component of the entire stirring mechanism 22, the stirring shaft is stably and flexibly rotatably connected to the top of the wall material mixing tank 21. This rotatable connection is usually achieved using high-precision bearings. The bearings can not only withstand the various loads generated by the stirring shaft during operation, but also ensure that the stirring shaft can rotate smoothly and stably under the drive of the motor, providing a reliable power transmission basis for the operation of the stirring blades. Meanwhile, the stirring shaft is typically made of high-strength, corrosion-resistant alloy steel to ensure structural integrity and performance stability during long-term use, even under various chemical substances and mechanical stresses present in the wall material preparation. This prevents deformation or breakage, ensuring continuous and normal stirring operations. Several stirring blades are circumferentially spaced on the stirring shaft. The blades are usually designed with a specific streamlined shape to reduce resistance between the blades and the wall material during stirring, allowing for more efficient material movement. Each blade is appropriately sized and angled to cover a sufficient area of ​​the wall material, while a suitable angle generates appropriate thrust and shear force during rotation. When the stirring shaft rotates under the drive of the motor, the stirring blades also move in a circular motion. Due to the circumferential spacing of the blades, they can stir the material in the wall material preparation tank 21 from different directions and positions during stirring. This multi-directional stirring action can break down potential localized concentration differences and agglomeration in the wall material, allowing for more thorough contact and mixing of various components. For example, for some highly viscous wall material components, the shear force generated by the stirring blades can disperse them into smaller particles, promoting their integration with other components; for wall material substances with different densities, the pushing action of the stirring blades can ensure their uniform distribution within the container, preventing stratification. This stirring mechanism 22 design significantly improves the mixing uniformity of the wall material formulation. The uniformly mixed wall material formulation provides a good foundation for subsequent integration with oils in the homogenization unit 3, resulting in a more uniform distribution of components and more stable product quality in the final fat powder product. Simultaneously, the efficient stirring action can also shorten stirring time, improve production efficiency, and reduce energy consumption.In addition, due to the reasonable design of the stirring mechanism 22, the residue and accumulation of materials during the stirring process are reduced, which facilitates the cleaning and maintenance of the wall material batching tank 21, further ensuring the hygiene standards of production and the long-term stable operation of the equipment.
