Description

Food extruder with control part of extrusion screw}

The present invention can be used by adjusting the gap (spacing) between the butting surfaces of the twin-screw extrusion screw, so that the food has an extrusion screw control unit that can maximize the efficiency of device use depending on the dough material by effectively stirring and transporting the dough depending on the characteristics of the dough material. It's about the extruder.

In general, twin-screw extruders are classified into a closed type (intermeshing type) in which a gap is formed and an open type (non-(intermeshing type)) in which a gap is formed, depending on the screw shape and the distance between the shafts. Depending on the direction of rotation of the shaft, there are co-directional and reverse screw extruders. It is classified as

Most of the two-screw extruders for food that use these two-screw extruders have screw blades (flight) between the drive gear coupled to the drive shaft of the drive screw and the driven gear coupled to the interlocking shaft of the interlocking screw. The extrusion material (dough) is extruded while being stirred and compressed by the width (axial channel) of the barrel, that is, the gap (gap) formed between the screw flight formed in the barrel and the screw blade.

Therefore, the extrusion function of a twin-screw extruder is most important in setting (fixing) the gap between the channels between the screw blades of each barrel according to the engagement state arrangement depending on the food dough.

Therefore, when the food extruder is first manufactured, the gap between the screw blades arranged in the meshing state of the two-axis extrusion screw is fixed according to the type of dough.

Various technologies have been previously disclosed in relation to food extruders using this twin-screw extruder technology, but examples include Patent Documents 1 to 6.

Patent Document 1 is not limited by the moisture content of the raw materials, and can handle high-viscosity or liquid raw materials. It is especially advantageous in handling protein-containing raw materials, and uses a twin-axial extrusion molding machine to transport the raw materials while extruding the molding machine. A twin-axial extrusion molding machine that produces various materials for food processing by continuously and uniformly producing gelatinized and puffed grains through a series of actions such as grinding, compression, shear mixing, melting, sterilization, reaction, and puffing that occur inside the body. It has been suggested.

Patent Document 2 divides the noodle making base into parts for each function and configures them so that they can be disassembled and assembled, so that each part can be processed independently. This ensures processing precision, and through this precision, the screw and angle It is possible to further improve the adhesion that narrows the gap between parts, and the adhesion increases the transfer amount and transfer pressure of the dough by screw rotation, improving the performance and efficiency of the noodle making machine by improving the straightness judged by the extrusion force compared to the driving force. A noodle making machine was proposed.

Patent Document 3 applies a molding die capable of producing buckwheat noodles with a good taste, and uses an extrusion means, a pressure control means, and an auxiliary heater to produce buckwheat noodles that are elastic and have a good taste, with the buckwheat content being 100% by weight. A buckwheat noodle manufacturing device for producing noodles was proposed.

Patent Document 4 proposes an extrusion device for producing barley ramen that can produce barley ramen with a barley content of 80% or more through multi-stage compression.

Patent Document 5 states that the raw materials can be uniformly mixed by a reverse screw while pressurizing and transferring the raw materials by means of a biaxial screw, and by inserting a plurality of unit screws formed at a predetermined length into a spline rotated by a drive motor, according to the type of raw materials. A plant-based soybean meat production device using a twin-screw extruder capable of alternating extrusion and mixing was proposed.

Patent Document 6 is a noodle that can vary the frictional heat required for manufacturing various noodles such as buckwheat noodles, noodles, and jjolmyeon, and can provide frictional heat exceeding the set value, so that buckwheat noodles can be manufactured using 100% buckwheat. A manufacturing device was proposed.

The above-mentioned patent documents construct an extruder suitable for the purpose depending on the type of compressed product (kneading material), but there is a disadvantage in that the compatibility of the proposed use depending on the characteristics of the kneading material due to the same structure is low.

In other words, the above-described patent documents have a structure in which the twin-screw extrusion screw is fixed on a parallel axis, and the extrusion action of the twin-screw extrusion screw creates the same gap between the screw wings of the first extrusion screw and the second extrusion screw regardless of the type of dough. By being fixed with a , the same extrusion (kneading) action is possible during spiral rotation, but there is a disadvantage in that it is difficult to manufacture a more efficient dough product.
