Background

The juice extractor (screw extrusion type juice extractor) is developed on the basis of the early cutterhead juice extractor, and the main working purpose of the juice extractor is to change fruits into juice so as to improve the taste and facilitate drinking.

At present, some juice machines on the market use large-size screw belts matched with mesh drums for juice extraction so as to treat large-size fruit blocks. However, in practical situations, the structure can only squeeze the fruit blocks with the diameter smaller than 70mm, and if the diameter of the fruit blocks is larger than 70mm, the fruit blocks can be squeezed only after being cut.

One of the main reasons is that the prior art extrusion screw, due to its own structural shape, limits the size of food material that it can receive and extrude, such that the screw cannot extrude larger sized pieces of fruit.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.

In the present invention, "radial dimension" means the maximum outer edge dimension in cross-sectional area, and "lift pitch of a screw extruder or screw feeder" means the distance between two cross-sections along the axial length of the screw.

Fig. 1 and 2 show an embodiment of the screw of the present invention, which comprises a screw body 10 and a screw extruder 20, the screw extruder 20 being provided on the screw body 10 for extruding food materials. The screw further includes a screw feeding body 30, and the screw feeding body 30 and the screw extruding body 20 are sequentially disposed on the screw body 10 in a screw manner from top to bottom in the height direction of the screw body 10. The radial dimension of the screw feeder 30 on the screw body 10 is gradually increased and then gradually decreased from top to bottom in the height direction of the screw body 10, and the maximum radial dimension of the screw feeder 30 is larger than the maximum radial dimension of the screw extruder 20.

When the screw is used for juicing, the spiral feeding body 30 positioned above the spiral extruding body 20 on the screw body 10 can cut, introduce and squeeze large-size food materials, the radial size part of the spiral feeding body 30 which is gradually increased is beneficial to introducing and cutting the food materials, and the radial size part of the spiral feeding body 30 which is gradually reduced is beneficial to being matched with the mesh cylinder to realize coarse juicing of the food materials. The maximum radial dimension of the spiral feeding body 30 is larger than the maximum radial dimension of the spiral extruding body 20, so that the spiral feeding body 30 with a large radial dimension can lead in and roughly extrude food materials, and then the spiral extruding body 20 with a small radial dimension can finely squeeze the food materials, so that juice outlet efficiency is improved. Therefore, the large-size food materials can be conveniently treated by adopting the screw rod, and the juice outlet efficiency is maintained.

As shown in fig. 2, the screw body 10 of the present embodiment is preferably semi-spindle-shaped, and the screw body 10 includes a radial dimension constant section 11, a first radial dimension gradual section 12, and a second radial dimension gradual section 13, which are sequentially connected from top to bottom. The diameter variation of the first radial-dimension transition 12 is larger than the diameter variation of the second radial-dimension transition 13. It should be noted that the transition portion between the radial-dimension constant section 11 and the first radial-dimension gradual section 12 should be subordinate to the radial-dimension constant section 11. When the screw body 10 is in use, the constant radial dimension section 11 extends out of the mesh cylinder and rises into the feeding shell, so that the screw body participates in the work of introducing food into the mesh cylinder. Let first radial dimension gradual change section 12 and the cooperation of the section of thick bamboo section of mesh section of thick bamboo carry out coarse pressing work to the food, first radial dimension gradual change section 12 diameter change is great, is favorable to cooperating the mesh section of thick bamboo to carry out the efficient preliminary pressing to the food. The second radial dimension gradual change section 13 can carry out the fine squeezing work with another section of thick bamboo cooperation of mesh section of thick bamboo to the food, and the diameter variation of second radial dimension gradual change section 13 is less, is favorable to cooperating the mesh section of thick bamboo to carry out the fine squeezing to the food, guarantees the play juice rate of food.

Based on the above, as shown in fig. 2 and 3, the radial dimension of the screw feed body 30 on the radial dimension constant section 11 gradually increases from top to bottom, and the radial dimension of the screw feed body 30 on the first radial dimension variable section 12 gradually decreases from top to bottom. In this way, the spiral feeding body 30 with gradually increasing radial size on the radial size constant section 11 is beneficial to introducing food materials into the mesh drum, while the spiral feeding body 30 with gradually decreasing radial size on the first radial size gradual section 12 is beneficial to making the first radial size gradual section 12 cooperate with the mesh drum to squeeze food materials efficiently.

Because the radial dimension of the second radial dimension gradual change section 13 is gradually increased, the radial dimension of the screw extrusion body 20 on the second radial dimension gradual change section 13 is gradually reduced from top to bottom in a matched manner, so that the second radial dimension gradual change section 13 can be more effectively matched with the mesh barrel to forcefully squeeze the food, and the juice squeezing efficiency of the screw is improved.

As a preferred embodiment, the lift pitch of the screw feeder 30 on the screw body 10 is greater than the lift pitch of the screw extruder 20 on the screw body 10. Because the spiral feeding body 30 is mainly responsible for introducing food into the mesh drum, the large-lift pitch plays an important role in introducing food into the mesh drum and stirring the food to roll transversely, and the smaller-lift pitch of the spiral extrusion body 20 is helpful for finely extruding the food, the structure can be used for squeezing the food with high efficiency and high extraction rate.

As shown in fig. 1 and 2, the lift pitch of the screw feed body 30 on the radial dimension constant section 11 is greater than the lift pitch of the screw feed body 30 on the first radial dimension variable section 12. Since the main function of the screw feed 30 on the radially dimensionally constant section 11 is to introduce foodstuff into the mesh drum, its larger lift pitch assists in its efficient introduction of foodstuff into the mesh drum. The spiral feeding body 30 on the first radial dimension transition section 12 participates in the squeezing process of the food material, and the smaller lift pitch is helpful for the screw to squeeze the food material.

As an alternative embodiment, the lift pitch of the screw extruder 20 on the second radial dimension transition 13 is constant.

As an alternative embodiment, the lift pitch of the screw extruder 20 on the second radial dimension transition 13 may be gradually reduced from top to bottom to increase the pushing force of the screw extruder 20 in the finish extrusion step.

As shown in fig. 3, in the present embodiment, the screw feeder 30 is provided with a beating block 31 extending at the maximum of the radial dimension on the screw body 10, and the beating block 31 is used for crushing the food material. When processing the food materials with larger size, the food materials retained in the feeding barrel can be smashed and stirred by the beating block 31, so that the food materials roll in the feeding space, and the food materials can be pushed into the extrusion space below the beating block by the spiral extrusion body which rotates subsequently.

As shown in fig. 2, as a preferred embodiment, the number of screw extruders 20 is plural, and the plural screw extruders 20 are uniformly distributed on the screw body 10. The plurality of screw extruders 20 can push the food material more uniformly with force to perform the fine squeezing process on the food material. The plurality of screw presses 20 form a plurality of slag pushing teeth 21 at the bottom position of the screw body 10, and the plurality of slag pushing teeth 21 are used for discharging slag. The pushing teeth 21 also have the function of extruding the food residues which are downwards moved to the bottom of the screw rod out of the juice machine through the slag discharging holes formed on the mesh drum after the final extrusion. In addition, the intermediate gear arranged at the bottom of the screw rod and matched with the gear arranged below the slag pushing teeth 21 can transmit the rotating motion to the net brush frame sleeved outside the net hole cylinder, so that the net hole cylinder is cleaned while rotating.

Fig. 4 shows a juice extractor according to the invention, which comprises a screw as described above. The juice machine can be used for conveniently processing large-size food materials and keeping juice outlet efficiency.

The juice machine can squeeze food materials with the diameter close to 100mm by using the screw rod. So that more fruits on the market can be directly squeezed without cutting, and the fruit squeezing machine is convenient for users to use.
