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 compounding 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 compound fried snack and adding seasoner. (2) Single drum, used for mixing compound fried snack and seasoner (ancillary use with flavoring hoister). (3) Double-drum, used for adding seasoner, and mixing it with compound fried snack food.

3.2.2.6    Machineries in packing & detection (option): (1) Cup type packing machine, used for packing compound fried snack with small size bag by heat-seal. (2) Multi-head weigher packing machine, used for packing compound fried 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 compound fried snack and removing dreg. (3) Stock bin (option), used for storing raw materials or finished product.
