modified starch production line
Product Description
Modified starch
Modified starch, also called starch derivatives, are prepared by physically, enzymatically, or chemically treating native starch to change its properties. Modified starches are used in practically all starch applications, such as in food products as a thickening agent, stabilizer or emulsifier; in pharmaceuticals as a disintegrant; as binder in coated paper. They are also used in many other applications. Starches are modified to enhance their performance in different applications. Starches may be modified to increase their stability against excessive heat, acid, shear, time, cooling, or freezing; to change their texture; to decrease or increase their viscosity; to lengthen or shorten gelatinization time; or to increase their visco-stability. Methods to make modified starch can be divided into physical methods and chemical methods. Extrusion method is one of physical methods.
- Modified starch samples introduction
- Raw materials: starch, guar gum, xanthan gum, the other additives.
- Humidity: the moisture is no more than 10%.
- Fineness: user-defined.
- Modified starch processing lines description
- Modified starch processing lines features
- Capacity range is large: our modified starch processing lines capacity range is from 100kg/hr to 2500kg/hr.
- Our modified starch 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.
- Our twin-screw extruder has self-clean function.
- Our extruders and dryers are equipped with inverters. The inverters are famous brands (Delta, LS, ABB, Siemens etc.).
- Our modified starch processing line automation degree is high, it need only 2-4 workers to operate.
- The production factors can be quantized and controllable.
- We can custom-make all the machineries for modified starch processing line as per users’ requirement. We supply OEM goods.
- All the materials touching food is food grade.
- Our twin-screw extruders are equipped with forced lubrication system. The driving method can be tape drive or direct-connected.
- N Modified starch processing line work flow
- Work flow: Raw material treatment---Extrusion---Drying---Grinding---Packing & Detection
- Machineries description in each process
- Machineries in raw material treatment: Mixers (include propeller type mixer, vertical type mixer, dry powder type mixer), used for mixing all raw materials and adding appropriate water (don’t need to add water into dry powder type mixer), to make the raw materials uniform.
- Machineries in extrusion: (1) Conditioner (option for small capacity lines, necessary for big capacity lines), used for pre-conditioning raw materials. (2) Twin-screw extruder, used for extruding and cutting.
- Machineries in drying: different dryers. Our dryers’ heating power source can be electricity, gas-fired burner (Baltur, Italy), oil-fired burner (Baltur, Italy) or steam (from boiler). It is up to users’ local power situation.
- Machineries in grinding: different capacities grinders or grinding groups, used for grinding self-finished product. (1) Grinder can be adopted to grind non-food industrial modified starch. (2) Grinding groups are composed by grinding machine, discharging device, dust collecting box and negative-pressure blower. They are s ested to adopted to grind food industrial modified starch.
- Machineries in packing & detection (option): (1) Big size bag packing machine, used for packing big size bags. (2) Weight detector, used for detecting the goods after packing. It can get rid of the finished product with unqualified weight. (3) Metal detector, used for detecting if there is any metal inside the bag and removing the unqualified one. (4) Weight and metal all-in-one detector, used for detecting both weight and metal, and removing the unqualified product.
- The other machineries may be adopted: (1) Transport machineries, they are screw conveyor, air 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) Stock bin (option), used for storing raw materials or finished product. (3) Boiler (option), used for supply steam to conditioner, extruder and dryer. Its power source (electricity, gas, oil) is due to user’s local power situation.
