In this embodiment, an included angle may be set between the pressing barrel casing 242 and the crushing barrel casing 244 as long as the food material can enter into the crushing barrel casing 244 from the pressing barrel casing 242, wherein, preferably, an included angle between the axis of the pressing barrel casing 242 and the axis of the crushing barrel casing 244 is greater than or equal to 90 ° and less than or equal to 135 °, that is, the pressing barrel is set horizontally or obliquely downward, so that the food material can enter into the pressing barrel or flow to the slag outlet in the pressing barrel without overcoming the gravity of the food material at least, and further the flow of the food material is smoother, wherein, further, an included angle between the axis of the pressing barrel casing 242 and the axis of the crushing barrel casing 244 is greater than 90 ° and less than or equal to 135 °, besides the flow of the food material by the pressing force of the pressing screw, the food material can flow out by the gravity of the pressing screw, so that, on one hand, the flow rate of the food material can be increased to increase the juice output speed, on the other hand can also fully extrude eating the material to improve juice rate, simultaneously, this kind of setting combines vertical machine and horizontal machine, therefore can make the product both have the advantage that vertical machine crushing effect is good, has the abundant advantage of horizontal machine extrusion again, and then can make promptly to eat the material by fully smashing, again can be fully extruded, and then can improve juice rate.
Wherein further, preferably, the axis of the pressing barrel casing 242 and the axis of the pulverizing barrel casing 244 form an included angle of 90 °.
Preferably, an included angle between the axis of the extrusion screw 1 and the axis of the crushing device 246 is greater than or equal to 75 degrees and less than or equal to 180 degrees, or an included angle between the axis of the extrusion screw 1 and the axis of the crushing device 246 is greater than or equal to 90 degrees and less than or equal to 135 degrees. This kind of setting can make extrusion bucket level or slope set up downwards to eat the material and enter into in the extrusion bucket or need not overcome the gravity of eating the material at least when flowing to the slag notch in the extrusion bucket, and then make the flow of eating the material more smooth and easy.
Wherein, furthermore, the axis of the extrusion screw 1 and the axis of the crushing device 246 form an included angle of 90 degrees.
In the above embodiment, preferably, the host component 22 further includes: the power module is used for supplying power to parts of the food processor 2, such as a driving device, and at least comprises a power plug which can be plugged into mains supply, so that the power plug can be directly connected with the mains supply to supply power to the food processor 2 in specific use.
In the above embodiments, preferably, the pressing barrel casing 242 is provided with a juice outlet and a juice outlet, wherein the food juice separated from the food material juice and the food residue in the pressing barrel casing is discharged from the juice outlet, and the food residue separated from the juice and the residue is discharged from the residue outlet.
In any of the above embodiments, the food processor 2 is preferably a juice extractor or a juicer, but the food processor 2 may also be other structures besides juice extractors and juicers, such as a juicer, a wall breaking machine, etc.
