Description

Technical Field

[0001] The invention relates to the technical field of juice extractors, and in particular to an extrusion type juice extractor for juice production. Background Art

[0002] The spiral juicer is a mechanical device that mainly uses pressure to squeeze out the liquid contained in the solid to achieve solid-liquid separation, while the spiral continuous juicer is a more commonly used continuous juicing equipment.

[0003] The spiral continuous juicer is mainly achieved through squeezing during its working process. At the beginning, the motor drives the reducer to rotate, and the reducer rotates with the help of the coupling with the screw; at the same time, the fruits and vegetables put in the feed hopper will be squeezed by the screw, so that the juice flows out of the screen cylinder and is discharged to the outside through the liquid accumulation tray. The water content of the fruits and vegetables will gradually decrease during the continuous squeezing, and finally discharged from the slag hopper. In the prior art, there are equidistant screws and variable pitch screws. For equidistant screws, it is necessary to pre-treat the fruits and vegetables waiting to be squeezed. , so that the material size is appropriate. In order to cope with fruits and vegetables of different sizes and improve the squeezing efficiency, a variable pitch screw is usually used for grading. For example, the spiral on the screw is divided into four sections. The first section refers to the feeding screw. Its pitch is the largest in this screw, and its main function is to transport the material; the second section is the pre-pressing screw, which has the characteristic of preliminary squeezing of the material, so that the moisture in the material can be squeezed out; the third and fourth sections are compression screws, which can continuously squeeze the fruits and vegetables further, so that the moisture contained in the material is forced to be removed.

[0004] However, when the horizontal screw is squeezing fruits and vegetables, the juice generated by the squeezed fruits and vegetables near the inner diameter of the screw needs to flow through the outer layer of fruits and vegetables before passing through the filter and entering the liquid accumulation tray, resulting in inconsistent squeezing degrees of fruits and vegetables between the same section of spiral sheets. Therefore, it is necessary to increase the length of the screw and increase the squeezing time to ensure the squeezing degree of fruits and vegetables.

[0005] In summary, there is an urgent need for an extrusion type juice extraction device for juice production that can guide the flow direction of juice after the inner layer of fruits and vegetables are squeezed and improve the squeezing efficiency. Summary of the invention

[0006] In view of the squeezing efficiency problems existing in the prior art, a squeezing device for juice production is proposed, which can guide the flow of juice after squeezing the inner layer of fruits and vegetables and improve the squeezing efficiency.

[0030] Please see attached Figure 3 , Figure 3The present invention is a schematic diagram of the screw of the squeeze type juice extraction device for juice production; the screw 5 includes a shaft 52 and a spiral sheet 51 on the shaft 52, the spiral sheet 51 is provided with a sieve column 8, the side wall of the sieve column 8 is provided with a plurality of sieve holes 81, the sieve column 8 is arranged along the spiral sheet 51, and presents a divergent shape with the shaft 52 as the axis, and the end of the sieve column 8 away from the screw 5 and the shaft 52 is an open opening structure; the sieve column 8 can be a cylindrical cavity, preferably, in this embodiment, the sieve column 8 is a conical trapezoidal cavity The bottom of the larger diameter of the conical table is the end away from the shaft 52, and the inner cavity of the conical table is opposite to the inner wall of the screen drum 2; it should be noted that the drawings in this embodiment are displayed using equidistant screws, and the difference between the sieve column 8 on the equidistant screw and the sieve column 8 on the variable pitch screw is the difference in size. The diameter of the sieve column 8 on the variable pitch screw is set according to the actual spacing between the spiral sheets 51, which will not affect the technical effect and usage, and the spiral sheet 51 located at the slag outlet 21 may not be provided with a sieve column 8.

[0031] The working principle of the present invention is as follows: the fruits and vegetables to be squeezed are put into the feed hopper 1, and the fruits and vegetables enter between the spiral pieces 51 in the screen cylinder 2. The screw 5 is driven to rotate by the rotating mechanism 6. During the rotation, the fruits and vegetables in the screw 5 are conveyed and squeezed. During the squeezing, the water in the fruits and vegetables will flow out of the screen to the liquid accumulation bucket 3, and the squeezed juice will be collected from the liquid outlet of the liquid accumulation bucket 3, and the waste residue will remain in the screen cylinder 2. After multiple layers of repeated squeezing by the screw 5, the fruit and vegetable waste residue will be conveyed to the residue outlet 21, and fall from the residue outlet 21 into the residue outlet 4 below, and will be guided to the corresponding collection container by the residue outlet 4; when the fruits and vegetables and other materials are squeezed by the spiral pieces 51 of the screw 5, due to the spiral pieces 51 provided with The sieve column 8 has a side wall with sieve holes 81, so that the juice squeezed out of the inner layer can be squeezed into the inner cavity of the sieve column 8 through the sieve holes 81 and flow out of the sieve cylinder 2 through the inner cavity, avoiding the need for the inner layer juice to flow to the outer layer and then be collected through the next round of squeezing. It is obvious that the squeezing juicing device for juice production described in the present invention can relatively shorten the length of the screw 5 and improve the squeezing efficiency, and the sieve column 8 protrudes from the surface of the spiral sheet 51, reducing the distance between the adjacent spiral sheets 51 and further increasing the clamping force; preferably, the sieve column 8 is a conical table structure, so that when the inner layer juice is squeezed into the sieve column 8, the juice is further facilitated to flow into the sieve column 8 under the action of gravity.

Preferably, the sieve columns 8 on adjacent spiral pieces 51 are adjacent along the direction of the shaft 52, so that when rotating, the squeezing forces provided by the two arc-shaped pieces form a linkage, further improving the juicing efficiency; at the same time, the height of the squeezing fan 83 is the same as the distance between the sieve column 8 and the inner wall of the sieve cylinder 2, so that the arc-shaped piece can extend out of the outside of the sieve column 8 and the debris in the sieve column 8 can fall off.
