Construction of Big Bag
Lots of components – only one aim:
Safe, fast and residue-free emptying of your Big Bags
A Big Bag emptying station essentially consists of the following core components:
- 1Base frame
- 2Feed solution
- 3Big Bag connection systems
- 4Emptying aids
- 5Product preparation
- 8Safety guards
Base frames must be designed stably so that they have the load capacity to carry the Big Bags and the components attached. Our frame versions:
Normal or stainless steel
Modular in various heights
Square or round profiles for hygienic zones
The Big Bags need to be lifted quickly and safely brought into their emptying position. We offer three options for loading the station with Big Bags:
Fork-lift truck and spider clamp
Combination with existing crane track
Crane runway integrated into the frame
We recommend working with crane tracks at high numbers of Big Bags to be processed.
The Big Bag outlet is fixed in the connecting system before emptying. Aspects to be considered in the choice of the optimal connection system are the dust formation of the product and the type of operation:
low-dust and dust-proof connecting systems
operated manually or pneumatically
Standard emptying equipment (low-dust)
Simple, low-cost and low-dust emptying devices
Stainless steel with various surfaces
With or without aspiration fittings
Strong clamp system with double seal
Manual operation with ergonomic manual tensioner
JEL Emptying funnel (dust-proof)
Emptying funnel with strong, dust-proof cover
All stainless-steel with carious surfaces and coarseness depths (also in hygienic design)
Strong clamp system with double sea
Funnel cover pressed manually or pneumatically
Two support brackets lift the Big Bag sideways while emptying. Material bridges above the outlet are broken up and even products with unfavorable flow properties can be discharged reliably.
Driven by pneumatic cylinder.
Rock function can be programmed via the control pannel.
Point and beam pressure systems
Mounted on the side of the frame, they press against the outer side of a Big Bag – punctual or over a larger area. Even caked product inside of the Big Bag is thus broken up and discharged.
Punctual or area pressure impulse, depending on product properties.
Driven by pneumatic cylinder.
The Big Bag is placed on the U-shaped vibration table while an oscillation motor sets the support plate in high frequency vibration. In that way, the material flow is set in motion immediately when the outlet is opened.
Springs in the base frame ensure that the Big Bag is tightened upwards during the emptying process thus supporting emptying of all residual material by avoiding folds.
No waste of material.
No residue in the Big Bag when disposing it.
Has your product compacted in the Big Bags during transport or storage? Have clumps formed? Or do you want to ensure that no foreign bodies are in the product when emptying the Big Bag?
We combine your Big Bag – emptying solution with various components so that your product can be processed optimally after emptying.
Safety sieving (foreign body separation)
Straining sieves (in case of clumps)
Over sized and fine grain sieving (separation of unwanted coarse and/or fine particles)
Grading (if you need various grain size fractions).
Crushing of agglomerations or clumps using lump breakers
Conveying & dosing
We offer you the option to enlarge your emptying station with various discharge, conveying and dosing units.
Mechanical dosing and transport units
Tube and trough screw conveyor
Discharge devices for viscously flowing products
Pneumatic conveyor and dosing units
Pneumatic feed shoe to beattached below emptying funnel or interim container
Blow-through sluices for dosed product feed into pneumatic conveyor lines
Support the discharge of bulk solids with poor flow properties or caked on product from Big Bags.
Ideal to prevent bridge and tunnel formation in material discharge
Whether simple or complex – the following generally applies: An emptying system must always be error-free, intuitive and safe to operate.
The more complex the emptying system is, the more important is…
that the operator maintains an overview of the process and
that operator errors are ruled out, e.g., by automation or certain control mechanisms.
Engelsmann offers you a comprehensive selection of control options: from the simple control unit to fully automated and programmable control systems with touch screens.
Safety guards are an important part of safety concepts.
They offer two advantages to the system operators:
They ensure that the operators have sufficient safety distance to critical points.
They prevent unauthorized persons being able to intervene in the process.
From us you get both: simple safety guards and special solutions with many different safety features or walkable operating platforms.
JEL SafeConnect: The adapter for
different outlet lengths!
Do you have to handle Big Bags with outlets in different lengths and do you look for a flexible, compact attachment system?
JEL SafeConnect is for connection of Big Bags with different outlet lengths in a simple and safe way. The very low construction height allows to implement it even in existing systems.
Dust-proof Big Bag emptying
Very low construction height
For Big Bag outlets with different diameters and lengths
Pneumatic seal or mechanical closing
Simple and user-friendly handling
Very compact– easy to integrate into emptying frames
Special sizes are also possible!
Materials with unfavorable flow properties often can not be emptied without aids. The most common problems when emptying these products out of Big Bags are the formation of bridges or tunnels and the clumping of the product.
The product in the Big Bag has very good flow characteristics. It can be completely emptied without any problems and without additional aids.
The product compacts directly above the Big Bag outlet and forms a bridge that prevents the material from flowing through the outlet.
Caking material sticks to the sides of the Big Bag and builds up a narrow tunnel inside. The product can flow out of the Big Bag through this tunnel only.
The materials solidifies in the Big Bag while storage – sometimes so massively that only large clumps remain, that cannot be emptied or processed. In extreme cases, a single, so-called “monoblock” forms.
Emptying aids can also impact from outside the Big Bag and ensure a continual flow of material during the emptying process even when the products have poor flow properties. Engelsmann emptying aids work either with the physical energy of rockers or with vibration. In each case, the energy generated from outside is transferred via the Big Bag to the product that is stored inside.
