Twin Head Bag-In-Box Fillers from Flex Pack Service and Supplies are semi automatic fillers with a built-in turbine flowmeter. These high speed twin head machines have a standard fill range between 2-25 litres and can fill up to 18 four litre bags per minute.
The operator loads a bag by hand into the bag holder and starts a fill cycle. The moving head feature automatically performs the decapping and recapping functions and a sanitary stainless steel fill head seats onto the bag spout when filling. Control over the batches occurs with a high speed counter which is fed signals from the sanitary turbine flowmeter.
Sequence control is programmed into the PLC based controls and adjustable times, fill volumes and other critical information are accessed using a touch screen which has been rated Nema4/IP65.
The bag-in-box system is based on the idea of a collapsible liquid container or bag inside a rigid carton package or box. These fillers are currently being used for the packaging of chemicals, fruit juices, milk products, oils, post mix syrup, water and wine.
