Ventilation Systems | Dust Collection & Aspiration | Atlas Yem

In modern feed manufacturing, air quality management is far more than a luxury; it is a critical necessity for operational efficiency, explosion prevention, and workplace health. Atlas Yem ventilation systems are engineered to capture dust and airborne particles from intake to packaging using high-velocity suction. Acting as the "lungs" of your facility, these systems utilize rational technology to minimize ATEX-related risks, extend machinery lifespan, and preserve the nutritional integrity of your final products.

Advanced Aspiration and Jet Filter Integration

Representing the pinnacle of industrial air filtration, our solutions combine jet filters, cyclones, and high-pressure radial fans tailored to your plant’s specific requirements. The system extracts dust-laden air from strategic points across the production line and processes it through micron-level filtration. While valuable particles are reclaimed and reintegrated into the production cycle to eliminate waste, the purified air is safely exhausted. Especially in pellet cooling and grinding stages, our units rapidly evacuate heat, maintaining optimal moisture balance and preventing mold growth.

The cooling phase is the most critical stage in preserving the shelf life and enhancing the physical durability of hot, moist pellets coming from the pellet mill. The Atlas Yem single deck cooler operates on an advanced counterflow principle, ensuring homogenous cooling from the core to the surface of the pellet. This rational engineering prevents thermal shock, thereby eliminating micro-cracks and ensuring the highest PDI (Pellet Durability Index) for your final product.

Counterflow Logic and Advanced Air Distribution

Often referred to in the industry as a counterflow pellet cooler, this system introduces cold air from the bottom while hot pellets descend from the top. This interaction ensures maximum energy efficiency while stabilizing the moisture content with millimetric precision. Atlas Yem’s cooling technology is equipped with a grid discharge mechanism to minimize fines and PLC-supported level sensors for automated flow control. With its stainless steel internal components and air-tight chassis, it eliminates contamination risks and upholds the highest facility hygiene standards.

Continuous Production and Advanced Counter-Flow Technology

The secret to quality in formulated feed production lies in extracting the heat and moisture from the core of the pellets gradually, without inducing thermal shock. The Double Deck Cooler operates on the globally recognized counter-flow principle. Cool air drawn from the bottom filters through the pellet beds on both decks and moves upwards.

The greatest advantage of this system is that while the product on the lower deck is being cooled and discharged, the upper deck continues to accumulate the new ration. As a result, the pellet mill never stops, and the production line runs continuously. The pneumatically and hydraulically controlled grate discharge system, developed by Atlas Yem engineering, gently evacuates the pellets without breaking them or creating dust fines. Thanks to the superior airlock design, the vacuum power in the system remains constant at all times. Preventing thermal shocks and enabling you to reach high PDI (Pellet Durability Index) values, this unit represents the digitized face of smart factories with its PLC-based intelligent automation.

Key Technical Advantages and Industry Variations

• Zero Contamination: Complete prevention of product mixing thanks to the independent operation of the upper and lower decks.

• Seamless Changeover: Flexible dual-hopper structure that eliminates the need to stop the pellet press during ration (recipe) changes.

• Maximum Space Saving: Efficient use of factory floor space with a vertical architecture in a single body, rather than using two separate coolers.

Aerodynamic Efficiency and Uninterrupted Extraction Power

Precise management of air flow and pressure in modern feed mills is absolutely mandatory both to balance the final moisture content of the product and to ensure strict environmental hygiene inside the plant. The Atlas Yem Industrial Aspirator series establishes this critical airflow with flawless thermodynamic equilibrium. Heavily dust-laden or high-temperature air emerging from various points of the production line (grinding, mixing, pelleting, and cooling) is suctioned by the powerful vacuum created by our high-speed aspirators and instantly directed to the filtration units.

The specialized aerodynamic angle of the rotor blades minimizes the friction resistance of the air within the housing; this innovative approach prevents motor overheating and yields a highly significant reduction in the facility's overall energy costs. Configurable as direct-coupled or belt-pulley driven, these centrifugal fans possess the flexibility to operate stably at varying rotational speeds based on the ambient temperature and dust density. The use of extra wear-resistant Hardox or equivalent reinforced steel in the inner casing significantly prolongs the unit's maintenance intervals, thereby safeguarding your operational profitability. Acoustic insulation options that minimize noise pollution and a vibration-damping heavy chassis structure elevate the occupational health and safety standards in your plant to the absolute peak. Atlas Yem aspirators are not just fans that direct air; they are rational technology centers that integrate industrial efficiency directly into your factory.

At the heart of industrial purity, Atlas Yem Cyclone units merge thermodynamic laws with rational design. The system receives dust-loaded air, drawn by aspirators, through a tangential inlet into the body. Here, a high-speed vortex is created, hurling dust particles heavier than air against the walls via centrifugal force. Under the influence of gravity, the particles slide down and collect at the bottom discharge due to the cyclone's conical shape, while the purified air is exhausted through the top to the atmosphere or filtration units.

Atlas Yem cyclones exhibit unique performance, especially in recovering fine dust generated in pelleting and grinding lines. This process not only prevents environmental pollution but also directly reduces production costs by minimizing raw material waste. Suitable for 24/7 continuous operation with wear-resistant internal surfaces and dust-tight body joints, these systems increase operational comfort with low maintenance requirements. With our custom designs optimized according to your facility's capacity and dust density, you get one step closer to your "zero waste" and "clean production" goals.

As the pinnacle of professional ventilation architecture, the Atlas Yem Jet Filter delivers 24/7 continuous performance based on the compressed air cleaning (Pulse-Jet) principle. When dust-laden air enters the filter body, it passes through high-efficiency specially woven bags; while particles are retained on the outer surface, the purified air is exhausted into the atmosphere. Solenoid valves, controlled by an electronic timer, send sudden and powerful pulses of compressed air into the bags to shake off the accumulated dust. This rational process prevents the filter bags from clogging, ensuring that the suction power remains stable at all times.

The raw material dust collected in the lower conical structure is reintegrated into the process via an airlock, minimizing material waste. Atlas Yem’s leak-proof body structure and explosion relief panels (ATEX compliant) provide the highest level of protection for your facility against the risks of dust explosions. With low compressed air consumption and extended bag life, these units are a technology center that lowers maintenance costs and guarantees operational fluidity.

In modern feed technologies, operational fluidity depends on the accurate processing of data. The Atlas Yem Electronic Jet Filter is equipped with differential pressure sensors that track the loading rate of filter bags with millimetric precision. Unlike classic timers, the system only sends high-pressure air pulses (pulse-jet) when necessary, thereby minimizing compressor load and energy consumption.

Operating in full integration with the airlock, this smart system reintegrates separated valuable dust into the process flawlessly while keeping cross-contamination risks under digital surveillance. Cleaning periods, valve opening times, and alarm history can be easily managed via the electronic timer and PLC touch screen. This electronic infrastructure, combined with Atlas Yem's rational design, proactively monitors dust explosion (ATEX) risks to maximize facility safety. This technology, which retains micron-level particles with 99.9% efficiency, is a long-lasting investment model that reduces maintenance costs.

In professional production processes, the flawless separation of air and raw material determines the stability of the process. The Atlas Yem Airlock Filter exhibits excellent sealing performance thanks to millimetric tolerances between the rotor blades and the housing. It discharges dust particles filtered from cyclones or jet filters without allowing pressurized air to escape or external air to leak in. This rational flow management prevents aspirators from being overloaded, thereby maximizing energy savings.

Available in cast iron or food-grade stainless steel housing options with high wear resistance, our airlock filters fully adapt to all material characteristics, including dust, granules, and pellets. Sealing life is taken to the highest level through replaceable sealing strips integrated into the tips of the rotor blades. Atlas Yem’s advanced engineering approach utilizes geared systems that generate high torque even at low speeds to prevent material clogging. Establishing a 24/7 secure operational foundation in your facility, these units are not just dischargers; they are the pressure guardians of the entire pneumatic system.
