3.       Fried expanded snack processing lines description

3.1   Fried expanded snack processing lines features

3.1.1          Capacity range: our fried expanded snack processing lines capacity is100-150kg/hr.

3.1.2          Fried expanded snack processing line has wide raw materials application range.

3.1.3          Our fried expanded snack processing lines’ extruders are twin-screw extruder, there is one couple of screws inside the barrel. The raw material of screws is 38CrMoAl (standard: GB/T 3077-1999). This material’s hardness and strength performance is excellent, which can bear high temperature and high pressure.

3.1.4          Our twin-screw extruder has self-clean function.

3.1.5          Our extruders, continuous fryer and cutting machines are equipped with inverters. The inverters are famous brands (Delta, LS, ABB, Siemens etc.).

3.1.6          Our fried expanded snack processing line automation degree is high, it need only 2 workers to operate.

3.1.7          The production factors can be quantized and controllable.

3.1.8          We can custom-make all the machineries for fried expanded snack processing line as per users’ requirement. We supply OEM goods.

3.1.9          All the materials touching food is food grade.

3.1.10      Except fried expanded snack, user can make most of expanded snack food by extruder (should equip with dryer).

3.1.11      Our twin-screw extruders are equipped with forced lubrication system. The driving method can be tape drive or direct-connected.

3.2   Compound fried snack processing line work flow

3.2.1          Work flow: Raw material treatment---Extrusion---Cutting---Frying---Flavoring---Packing & Detection

3.2.2          Machineries description in each process

3.2.2.1    Machineries in raw material treatment: (1) Grinder or grinding group (option), used for grinding raw materials. (2) Mixer, used for mixing all raw materials and adding appropriate water, to make the raw materials uniform.

3.2.2.2    Machineries in extrusion: (1) Conditioner (option), used for pre-conditioning raw materials. (2) Twin-screw extruder, used for extruding and shaping.

3.2.2.3    Machine in cutting: different shapes die cutting machines, used for straightening and cutting self-finished product.

3.2.2.4    Machineries in frying: different fryers: (1) Automatic fryer, this is frying by batch, which includes frying machine (main machine), de-oil machine and finished product conveyor. (2) Continuous fryer, this fryer is belt conveying type fryer. Frying belt brings self-finished product through oil. Our fryers’ heating power source can be electricity, gas-fired burner (Baltur,Italy), or oil-fired burner (Baltur,Italy). It is up to users’ local power situation. (3) De-oil machine, used for de-oiling and collecting redundant oil to cyclic utilization.

3.2.2.5    Machineries in flavoring: (1) Flavoring hoister, used for hoisting fried expanded snack and adding seasoner. (2) Single drum, used for mixing fried expanded snack and seasoner (ancillary use with flavoring hoister). (3) Double-drum, used for adding seasoner, and mixing it with fried expanded snack.

3.2.2.6    Machineries in packing & detection (option): (1) Cup type packing machine, used for packing fried expanded snack with small size bag by heat-seal. (2) Multi-head weigher packing machine, used for packing fried expanded snack with medium size bag by heat-seal. (3) Big size bag packing machine, used for packing big size bags. (4) Weight detector, used for detecting the goods after packing. It can get rid of the finished product with unqualified weight. (5) Metal detector, used for detecting if there is any metal inside the bag and removing the unqualified one. (6) Weight and metal all-in-one detector, used for detecting both weight and metal, and removing the unqualified product.

3.2.2.7    The other machineries may be adopted: (1) Transport machineries, they are screw conveyor, cooling conveyor, hoister, vertical type bucket elevator, Z type bucket elevator, vacuum suction machine and negative pressure suction machine. They are used for conveying raw materials, self-finished product and finished product between the other machineries. (2) Vibrating screen (option), used for screening fried expanded snack and removing dreg. (3) Stock bin (option), used for storing raw materials or finished product.
