Solutions

Laidig is an industry leader in bulk storage and reclaim, specializing in systems for extracting hard-to-flow raw materials from conical and/or flat-bottom silos.

When materials stored in silos do not discharge properly, two types of actions are typically taken:

• For large silos: Workers enter to manually unload the material with shovels.
• For smaller silos: The walls or cone of the silo are struck to dislodge the material and enable flow.

In either case, these methods have significant drawbacks. In the first, there is a severe risk to human life, and in the second, long-term damage occurs due to dents in the silos. At Clivio Solutions, we offer the ideal solution to prevent workers from entering silos or striking their walls.

Key advantages of Laidig extractor systems include:

• Safety: Eliminates life-threatening risks for operators.
• Sanitation: Prevents rat holing and material buildup.
• Traceability: Ensures FIFO (First In, First Out) system compliance.
• Capacity: Enables complete filling and emptying of silos, maximizing their capacity.

In the following video, we can see a comparison between silos that do not have a Laidig system and silos that do. This clearly demonstrates the significant advantages mentioned earlier.

If you have a conical silo, the ideal equipment for your application is the Cone Bottom model (available in electric and hydraulic versions, depending on your requirements).

If you are looking for a solution for flat-bottom silos and low-flow materials, such as animal-derived flours or soy paste, the suitable reclaimer models are the X-tractor, Cantilever, or Track-Drive. For these applications, the silo can operate fully loaded, and discharge will be efficient and safe thanks to the reclaimer, which keeps the bottom 100% active during the unloading process.

If you need to sweep the bottom once the product stops flowing freely by gravity, the suitable model is the Clean Sweep. This silo bottom sweeper activates only for the final product discharge and cleaning, making it a very common solution for grains, legumes, or free-flowing products.

No matter the discharge issue with your silo, together with Laidig, we have the ideal solution to protect your company's team and prevent risks.

Many raw materials are received in big bags, and safely and automatically unloading the product can be a challenge. With Comav unloaders, you can make this process much more efficient and secure.

If the big bags are disposable, the opening blades will do their job by tearing the bottom of the big bag. On the other hand, if the big bag is reusable and features a sleeve or neck at the bottom, the appropriate equipment is one that allows manual intervention by the operator for opening. At Clivio Solutions, together with Comav, we offer both opening options.

The ideal equipment for your plant will be the one that matches the level of automation and unloading capacity you want to achieve, always prioritizing safety.

When a high unloading capacity is required, we must resort to a set of unloaders, which can work in parallel without any issues. An example of such installations is shown below, where the same feeding channel using conveyor rollers is used for both unloading systems.

Along with Comav, a wide range of systems for big bag opening, with or without unloading sleeves, is offered. For these applications, multiple accessories are available, such as:

• Cylinders for emptying the bottom residual of the big bag.
• Hoists with cable or battery (wireless).
• Rotary valves for pneumatic transport or other types of transport.
• Knife valves for sealing the big bag sleeve.
• Lump breakers.
• Systems for extracting and filtering the pollution generated and reinserting the dust into the transport system to maximize utilization.

The equipment has a flat hopper with a special gasket and a safety structure useful for disengaging the sleeve.

Depalletizers are automatic or semi-automatic machines that pick up the bags and use their blades to open them, unloading the material.

For cases requiring a semi-automatic application, the SVR NT model is ideal: The operator manually places the bags or uses a vacuum lifter, and the system guides the bag via an elevation belt to the opening area, where the bags are emptied individually.

If greater capacity and/or a higher level of automation is required, the SVR DEPA model is the perfect choice: The entire pallet is handled, and the system overturns the pallet with all the bags onto a small conveyor belt that feeds the cutting blade set, proceeding with the opening and emptying of the material.

No matter which equipment suits your needs, these depalletizers will help you achieve:

• High efficiency and automation in the bag-opening process.
• 99.9% emptying and utilization of materials.
• Excellent ergonomic and safety benefits for operators.

Single and/or double hopper scales for macro-dosing are designed and built to meet demand with optimal operational reliability in modern process industries. With the JesHopper scale, it is possible to dose large batches. Hopper scales are designed for fast, accurate, and reliable feeding and discharge of materials such as grains and flours.

All Jesma hopper scales are designed and supplied with a modular construction, ensuring easy transport and a high degree of flexibility, allowing for future expansions without the need for major reconstructions.

Our standard range offers capacities from 200 kg to 10,000 kg.

Single scales

Consist of a weighing hopper, load cells, support legs, and space for a lower conveyor. They provide great flexibility and various adjustment possibilities. The material is filled through dosing devices from the top, and once the desired amount of material/product is reached, the JesHopper Single empties via the chain conveyor located at the bottom of the weighing hopper.

Double scales

The JesHopper Double is equipped with two hoppers: one for weighing and one for loading/storage. This allows a new load to begin while the previous one is being emptied, as the weighed load is quickly transferred to the lower hopper. This significantly increases the number of batches per hour.

The main difference between a single hopper scale and a double hopper scale is the ability to start weighing a new load before the system is emptied. The JesHopper Double has a higher batch capacity per hour since its design allows the weighing container to be filled while the previous batch is being emptied.

Microdosing systems have been specially developed for the fine dosing of ingredients, additives, and raw materials, where overdosing of micro-ingredients can be costly.

A key condition for a high-quality final product is controlled and precise dosing of ingredients. Micro and nano dosing systems are specially developed for the accurate dosing of ingredients. At Jesma, each system is tailored to meet the customer's requirements, and by carefully considering the product's characteristics, it makes precise dosing possible even for low-flow products.

With our technology, you will achieve:

• Process safety: Avoid human errors such as placing a product in the wrong silo (silo opening system via barcode).
• Cylindrical silos: Prevent product sticking in corners and eliminate rat holing.
• Silo bottom scraper: Ensures a continuous and free flow for all raw materials.
• Propeller and pneumatic lid: Maximizes precision and stops the flow at the exact moment.
• Teflon-coated and cylindrical scales: Ensures complete and quick discharge.
• Dust aspiration filtration system.

Below is an installation featuring multiple micro and nano dosing units installed in Poland.

The system can be arranged in circular, semi-circular, square, or other required layouts depending on the available space and location. Jesma offers various types of micro scales for the dosing system, each tailored to meet client needs and designed to guarantee complete emptying of the weighing container. The silos are available with live bottoms featuring scrapers and stirring screws, ensuring complete discharge of low-flowability materials and uniform feeding of the dosing screw.

Nano dosing scales
The JesBatch Nano dosing scale is designed to eliminate cross-contamination and operate with very high static precision for dosing and weighing small quantities of ingredients. The scale consists of a Teflon-coated weighing container that empties by being pneumatically tilted and vibrated with a pneumatic hammer to ensure complete emptying between batches. These scales range from 2 kg (+/- 0.5 g) to 30 kg (+/- 7 g).

Micro dosing scales
The JesBatch Micro scale features a weighing container with pneumatically activated bottom flaps for emptying. The Teflon-coated flaps open 90° to ensure complete emptying between batches. These scales range from 50 kg (+/- 10 g) to 200 kg (+/- 40 g).

Medi dosing scales
Jesma completes the range of dosing scales with the JesBatch Medi, designed for medium-sized ingredient dosing. To prevent dust accumulation in the environment, a slight negative pressure must be maintained in the scale, requiring aspiration. Additionally, the air from the lower pneumatic transport system must not affect the weighing process. This is achieved by installing a valve above the transport system. These scales range from 400 kg (+/- 100 g) to 1000 kg (+/- 250 g).

All scales are supplied with completely smooth interiors to ensure optimal emptying and minimal cross-contamination, combined with a sturdy and rigid construction for the highest possible operational reliability.

The need for flow measurement and control is essential in many stages of the process. Together with Jesma, we are able to measure product flow reliably, with two very useful alternatives depending on the application.

If we have available height space, the recommended system is JesIntake. However, if height is limited, the JesBelt weighing belts are the ideal solution.

The JesIntake range of scales is specially designed for inline weighing of bulk materials such as powders, granules, grains, and more, focusing on operational reliability and high precision. The equipment series includes a standard range of 13 sizes, with capacities from 12 m³/h to 2500 m³/h, making them suitable for handling high flow rates while maintaining high accuracy.

If height is limited, the solution to apply is a JesBelt conveyor, which features an incremental encoder (tachometer) mounted on the roller to allow continuous monitoring of the belt and ensure an immediate alarm signal in case of irregularities in belt transmission. The belt is equipped with load cells that guarantee high precision even with irregular material flow. The weighing conveyor is designed and built for continuous weighing of material transported on a belt or for regulating a specific material flow.

If an immediate solution is required, the JesBelt F1 is our standard range of belt weighers. With 1% accuracy and versatile functionality, it ensures precise and efficient performance. Its user-friendly design simplifies maintenance with easy belt replacement and integrated cleaning features, minimizing downtime.

The JesBelt F1 range is available in three configurations: basic, standard, and complete.

The loss-in-weight feeder is a fully electronic weighing system, specially designed for the continuous dosing of additives with high dynamic accuracy, including the critical stage of refilling the weighing container, with flow rates from 2 tons/hour to 50 tons/hour.

The operating principle of an LIW system involves repeated static weighing of the product container to determine and regulate mass flow. The product container is gradually emptied, and the relationship between the weight loss and the discharge system speed provides the quantity signal, which adjusts the dosing rate to the required value.

The product container empties slowly, and once a preset value is reached, it needs to be refilled. The controller automatically switches the system to "filling mode". In filling mode, the control system uses historical values to maintain the correct relationship between the discharge speed, the required dosed amount, and the container's contents. Based on the acquired historical data, the correct discharge speed is determined in relation to the required dosed amount and the hopper content. Once the weighing container is refilled, the system returns to normal operation, ensuring accuracy even during the LIW filling phase.

Commonly, in pet food production processes, both dry and wet by-products are generated, each with different characteristics in terms of physicochemical parameters.

Most fines come from sieves, dryers, coolers, cyclones, and conveyors, with low moisture content and variable temperature. Another dry by-product, considered waste, is the rejected or defective final product that does not meet quality standards to be delivered to the end customer.

On the other hand, wet by-products originate during extruder stops and starts. Due to their high moisture content, these by-products are often very challenging to handle, as they decompose quickly and typically appear as sticky lumps.

The By-Product Recovery System (SRS) recovers solids generated at any point in the process, maximizing both products and production time. The recovery of by-products is done quickly, preventing material decomposition, especially when dealing with wet by-products from extruder startups and shutdowns.

Its most important advantages:

• Utilizes 99.9% of by-products.
• Saves costs and reprocessing time.
• Optimizes the manufacturing process.
• Improves traceability.
• Produces a highly homogeneous slurry.
• Easy to clean.
• Can be installed horizontally or vertically.

The addition of slurry replaces part of the water added to the preconditioner. Therefore, it is essential for this process to be carried out in a controlled manner using electronic signals, as the amount of water entering the preconditioner/extruder directly and through the SRS must be continuously monitored. This control system makes the process entirely automatic, with minimal human intervention.

With the SRS, we can not only recover by-products generated throughout the process but also add fresh meat to create super-premium recipes. The system can be easily adapted to add emulsified meat, or we can even provide a complete solution to process fresh and/or frozen meat, transforming it into an emulsion that can be injected in a controlled manner.

In the most comprehensive projects, the system includes:

• Reception of fresh and/or frozen meat
• Cutter or grinder
• Intermediate storage hopper
• Mixer with emulsifier
• Modified SRS for injecting by-products + emulsified meat.

Aerox is the manufacturer of the Aerox Injector, a device that eliminates bad odors produced in industrial processes and is recognized as "the best available technology." It uses non-thermal plasma to generate free oxygen radicals, which react with the odorous air and prevent them from being detectable by the human nose.

The main advantages of the Aerox Injector:

• Eliminates up to 95% of odors.
• Works in 0.5 seconds.
• Consumes minimal electrical energy.
• Has a compact size.
• Does not use fuels, chemicals, or water.
• Generates no waste.
• Easy to install and maintain.

The system includes a small fan that extracts air from the environment and pushes it through a set of filters and a heater. These components purify the air and reduce its relative humidity. Once clean and free from condensation risk, the air circulates through the cold plasma modules, where oxygen radicals are generated. These radicals are injected into the process duct and react quickly with odorous gases, making them imperceptible to the human nose.

The injection principle ensures that process air (with humidity, temperature, and dust) does not enter the plasma modules of the equipment, which can be considered the "heart" of the system. This scheme of injecting oxygen radicals generated from treated air can be represented as follows:

In addition to the injection principle, another very important advantage is the compact size of the equipment, which does not exceed 6.5 meters in length. It also allows for multiple configurations and the installation of separate parts connected by ducts.

Together with Aerox, we help our clients reduce emissions and comply with industrial and governmental regulations. Their innovative technique for eliminating odors in humid air processes has become the preferred solution for global market leaders.

Chain-Vey offers equipment for transporting products using discs and chains. The tubular conveyors are efficient, food-safe, low-maintenance, flexible, and can incorporate a cleaning system.

It is the ideal type of transport for delicate products that need to maintain their structure, as it moves them gently. This ensures a high-quality final product.

The systems can be found in different sizes, depending on the target capacity sought, and the wide variety of available diameters allows us to adjust very precisely to the requirement.

These systems offer the possibility of incorporating various cleaning systems, both dry and wet, which helps save a significant amount of downtime and labor.

• For dry cleaning: polyurethane discs, sponges, abrasive and/or metal-detectable discs, passive and/or motorized cleaning brushes.
• For wet cleaning, we offer CIP systems of different grades.

Additionally, certain greasy or oily products tend to react with the iron present in carbon steel or even with the iron found in stainless steel. For this reason, it is possible to pigment the internal wall of the tubes with an acid film, which creates a passivation layer on the material, providing a non-reactive surface for the product. This ensures the transported product retains its integrity and original color, without undergoing alterations.

The system is capable of reversing its rotation direction, making it highly efficient when filling a large set of silos positioned in two rows. This means simply pressing a button, and the system reverses its rotation by 180°.

All our tubular conveyor systems are robust, hygienic, gentle, and quiet. The durable, low-friction discs are designed to reduce maintenance costs and energy consumption.

It is possible to perform an internal visual inspection of the system thanks to its easily attachable integrated camera. This allows you to check the system's cleanliness and prevent potential issues. The study results will appear as follows:

Assembling the system is very simple and quick. Even joining the chain takes no more than a minute. Thanks to the polyurethane disc, we guarantee two functions: a perfect link between the chain segments and continuous cleaning of the internal walls of the tubes.
