The extrusion technology used in the twin-screw extruder is one of the high and new technologies of modern food engineering. The twin-screw extruder is also one of the components of the Nutrition rice production line. It is widely used in the processing of cereals and snack food in agricultural products Food processing fields such as dying, brewing, deformation and precipitation.
The composition of Nutrition rice production line The twin-screw extruder is mainly composed of a feeding system, a backlog system, a rotary cutting system, a heating system, a transmission system, a lubrication system, and a control system. The extruder feeding system, drive system, and rotary cutting system all adopt frequency conversion speed regulation, with strong power and stable operation. Automatic lubrication and forced cooling ensure the safe operation of the extruder. For different raw materials, single-screw and twin-screw feeding systems are selected to ensure uniform, stable and reliable feeding. The screw is processed by a special process, wear-resistant and fatigue-resistant, and has a long service life.
Equipment system composition:
(1) Power drive system: consists of main motor and distribution box;
(2) Extrusion system: consists of screw, barrel and connecting section;
(3) Heating system: consists of a heating ring surrounding the barrel;
(4) Cooling system: consists of water jacket, water pump, and cooling pipeline;
(5)Electrical control system: motor speed control is frequency conversion speed control, frequency converter uses Delta frequency converter, temperature control is a special control system, 10.5-inch true color man-machine interface, temperature, speed setting and control can be performed Display die pressure value;
(6) The machine housing is made of stainless steel.
The advantages of twin-screw extruders: parameter detection is more intuitive, operation is more convenient, functionality is stronger and more professional, and the process integrity is more comprehensive. The machine is small in size, small in area, easy to transport, low in output, and low in power consumption. Disadvantages of twin-screw extruder: Due to low energy consumption and insufficient extrusion strength, the degree of expansion is lower than that of conventional production equipment, and the expansion effect and taste of the produced food particles will be slightly lacking. this is normal.
