Benefits
Tetra Pak® Big Bag Filler is a complete filling solution consisting of the following main components: a filling head equipped with automatic hooks and highly accurate load cells for weighing, a densification table and a system of shuttles and/or carriages that transfer the big bag between positions and from the high care to the lower care area. In addition, several options can be integrated into the unit such as a metal detector and ejector, a sampler, a heat sealer or a post-gassing unit.
The unit enables you to keep up with a high rate of production with a limited amount of manual labour while meeting all the quality and safety standards.
Capacity:
8 to 10 big bags/hour depending on size of the bag and configuration of the unit.
Height of bags: 150 to 220 cm.
Weight of bags: 700 to 1,500 kg.
Applications:
Dairy and nutrition applications.
Features
Choice of two configurations
Designed for a high care area
Many of our powder handling customers require a unit where filling and sealing are completed in an enclosed high care area with an airlock. In that case, we can offer a design that includes a shuttle with an overhead transfer carriage to move the big bag out into the airlock. Alternatively, a low-level belt conveyor can be used. The choice is yours. Either way there is no need for wooden pallets which can be a source of contamination.
High filling capacity
Up to 10 bags per hour
This unit has a high filling capacity competitive with anything on the market. The figure of 10 bags per hour is fully realistic when handling typical big bags with a capacity of one tonne and with no pre-gassing. Pre-gassing might slow down the rate of filling. However, if you want to use inert gas to modify the atmosphere while still maintaining the same speed, we offer the innovative option of post-gassing as an alternative.
High level of automation
Almost fully automatic operation
Only one operator is needed to perform two simple tasks: hooking up the empty big bag and sealing it afterwards. The rest of the steps are automatic. This keeps operator intervention to a minimum and reduces the risk of human error. We’ve thought of operator safety by creating an ergonomic working position with a tilted support rail when hooking on bags. When filled, the bags are released automatically from the hooks and conveyed away in an overhead carriage or a shuttle.
Options
ATEX heat sealer
The safe way to seal a big bag
ATEX certification is required for equipment in a potentially explosive environment where powder can be released into the air. It’s reassuring to know that our heat sealer meets this requirement. In addition, it operates by impulse heat sealing. Sealing is instant with no warm-up time needed. This decreases the risk of the operator getting burnt compared to sealers kept at a constant high temperature.
Elevator
For big bag heights of 150 - 220 cm
Big bags come in many different sizes. Our standard filling station handles bags about 150 cm high on a fixed base. The optional elevator handles different big bag heights from 150 to 220 cm with a working load up to 1,500 kg. Cleaning is easy because the cantilevered system gives access for cleaning below the elevator and the exterior is made of stainless steel.
Metal detector
Fully integrated into the design
Though the metal detection system is an option, it is designed to be an integrated part of the filler station. The rejection system is on sliding rails and can be pulled out for easy cleaning. If a foreign object is detected, a diverter valve opens a flap to remove powder surrounding the object.
Pre-gassing and post-gassing
Extend shelf life by removing oxygen
There are two ways of modifying the atmosphere in order to extend shelf life. Pre-gassing means that the powder is filled when it is already in a protected atmosphere and the big bag is then sealed on the filling station. Post-gassing is an alternative where the oxygen is removed after packing in a big bag by displacing the oxygen with nitrogen gas. In comparison, you reduce the consumption of nitrogen giving lower gas costs.
