    5.What Are Common Nut Packaging Machines?

    Common Nut Packaging Machines

    Nut packaging machines are an integral component of various industries. With each passing day, new and improved types of nut packaging machines are introduced in the market. This makes the selection of these types of equipment fairly difficult for packaging lines.

    Some basic information about common types of nut packaging machines is penned below for your understanding. This will help you in purchasing the right and suitable machine for your business.

    Horizontal Form Fill and Seal Machine (HFFS)

    Horizontal Form Fill and Seal Machine

    It is equipment that makes a pouch or a bag from plastic or paper film material and then fills it with nuts. Sealing is also performed by HFFS after filling. In these equipments, packaging operation is carried out in a horizontal direction.

    These machines present various advantages to nut packaging lines since they save film material, have a lower packaging error rate, and can speedily package nut and other granular products.

    Working Principle

    Working Principle

    The film material is shipped as roll stock and is unwind by the set of roller positioned at one end of HFFS machine. This material is folded in half and moved in horizontal direction to the forming tube which forms the bag according to the required shape. The forming collar is essential in shaping the film into a desired shaped pouch.

    Vertical and bottom sealing is done by sealing elements or jaws. The nuts are filled inside partially sealed bags with the help of a dosing unit. After this, the bag is sealed from the top. The sealed bag is detached from the film web via a cutting knife and then are removed from the machine.

    Vertical Form Fill and Seal Machine (VFFS)

    Vertical Form Fill and Seal Machine

    These are the wrapping machines in which nuts in filled inside the half done pouches using gravitational force. These equipments can be adjusted to produce a variety of different packaging styles such as zipper pouches, sachets, standup pouches, etc.

    VFFS machines are ideal for packaging lines with constrained space as they have smaller footprint.

    Working Principle

    Working Principle-1

    The first set of film rollers is employed for unwinding of film and also for maintaining said film material under proper tension. The film goes across rollers to form tube present on top of the machine. The film is wrapped around forming a tube so that it can be shaped in the required bag style.

    Side and bottom sealing are carried out by heating element and then nuts are introduced in bags from top. After loading top side seals are made and cutters are employed for the separation of two bags.

    Premade Pouch Packaging Machine

    Premade Pouch Packaging Machine

    This machine is the most commonly used instrument for packaging of nuts. It preserves nutritional quality for safe consumption of nuts. Pre-formed bags are available in variety of shapes and design so these equipments are best for creating your own distinct brand identity.

    As there is no need for making bags hence it saves your packaging time.

    Working Principle

    Working Principle-2

    As the name indicates, these machines employ pre-formed bags for filling the nuts. First, multiple bags are loaded inside the machine pouch loader. Grippers take bags one by one and deliver them to the opening station where the air is blown inside the bags to inflate them.

    The dosing unit or auger fillers equipped with pre-made pouch packaging machines drop nuts in these inflated bags. These filled bags are then hermetically sealed by means of heat sealing plates.

    Sachet Packaging Machines

    Sachet Packaging Machines

    These equipments are perfect for packaging nuts for retail distribution. Sachet packaging machines design 3 or 4 sided economic sachets that are the preferred choice of many consumers. These sachets are lightweight and are convenient to carry.

    These machines pack small quantities of nuts in sachet. They offer businesses high speed packaging and easy maintenance.

    Working Principle

    Working Principle-3

    Sachet packaging machines employ film roll stock for forming sachet. The unwinding rollers assist in unwinding of film and are also responsible for keeping the film under appropriate tension. Sachets are formed by the synchronized working of a cutter which cut the film into front and back halves.

    These halves are passed to forming structure and are joined to form sachet like bag. Sealing elements glue sachet from bottom and sides using heat. Nuts are then loaded inside these sachets and then hermetically sealed at the top side.

    Pillow Packaging Machines

    Pillow Packaging Machines

    It is also referred to as a pillow wrapping machine. These equipments are routinely used for packaging of nuts in pillow pouches. Pillow packaging machines consume less film material than other nut packaging machines which also saves film purchasing costs.

    These styled pouches are convenient to produce, and more pouches are packaged in a short time by pillow packaging machines.

    Working Principle

    Working Principle-4

    For packaging of nuts, the film roll is placed on the roller shaft and the product to be packaged is placed on the conveyors belt or loaded inside the hopper. The rollers unwind packaging film and cone shaped forming structure heat and shapes pillow package from packaging film.

    The material is molded into the required design by forming structure and heating elements. Conveyors belts transport the products to the filling station where they are filled inside pillow pouches. Conversely, nuts are dropped into pillow packs via feeders.

    Transverse sealing cutters create transverse sealing and then cut pillow bag from its partner.
