[0002] my country is a major global producer of fruits and vegetables, with annual production of apples, pears, and other fruits and vegetables ranking among the world's top. These fruits and vegetables not only meet domestic consumption needs but are also widely used in the production of deep-processed products such as juices and jams. In recent years, as people's requirements for food quality and nutrition have continued to increase, the fruit and vegetable deep-processing industry has set higher standards for juice extraction technology. However, traditional juice extraction processes still have significant shortcomings in practical applications, especially the ease with which juice comes into contact with air and oxidizes rapidly during extraction. Oxidized juice has a generally poor taste and color, significantly impacting and complicating subsequent deep processing. Existing extraction devices have simple structures, involving crushing followed by direct compression and filtration, which leads to juice oxidation after crushing. These problems directly affect the market competitiveness of juice and the effectiveness of subsequent deep processing, while also increasing the cost burden on processing enterprises. Therefore, a juice adsorption extraction device is proposed to solve the above problems. Utility Model Content

[0019] Please see Figure 1-5 This utility model provides a technical solution: a juice adsorption extraction device, including an extraction shell 4 and a slicing blade assembly 3. The internal cavity of the extraction shell 4, from left to right, is arranged with a pressing chamber 5, a rotor conveying chamber 9, a crushing chamber 11, and a crushing conveying chamber 13. The extraction shell 4 can be designed as an integral structure or a split structure, depending on customer requirements. The pressing chamber 5, rotor conveying chamber 9, and crushing conveying chamber 13 are respectively equipped with a pressing screw 6, a rotor 26, and a conveying screw 12, and are connected by a connecting flange 10. A slag outlet pressure plate 17 is provided at the left end of the pressing screw 6, and a spring 16 is provided on the outside of the slag outlet pressure plate 17. A blade assembly is provided in the crushing chamber 11, including an upper crushing blade 19 and a lower crushing blade 20. The lower crushing blade 20 is positioned on the conveying screw 12. On the left side of the shaft, the upper crushing blade 19 is set on the inner wall of the crushing chamber 11. The upper crushing blade 19 is a stationary blade, and the lower crushing blade 20 is a stationary blade. The upper crushing blade 19 and the lower crushing blade 20 rotate relative to each other. Under the combined action of the blades, the material is completely crushed into fine particles. The upper cavity of the conveying screw 12 is equipped with a slicing blade group 3. The upper part of the slicing blade group 3 is equipped with a feed hopper 2. The slicing blade group 3 is connected with a cutting diameter smaller than the material diameter. There are two slicing blade groups 3, which are installed below the feed hopper 2. The material falls onto the slicing blades that rotate relative to each other in the slicing blade group 3 through the feed hopper 2. After being incompletely sliced, the material falls into the crushing and conveying chamber 13. It is initially sliced ​​into pieces by the slicing blade group 3 but not completely separated, and still maintains the original state of the fruit and vegetables. This state can minimize the area of ​​the material pulp in contact with air and reduce the degree of oxidation.

[0020] A slicing motor 1 is installed on the upper right end of the extraction housing 4. The slicing motor 1 is connected to the slicing blade assembly 3 through a sprocket transmission assembly 15. The slicing motor 1 drives the slicing blade assembly 3 to rotate relative to each other through the sprocket transmission assembly 15, thereby cutting the material. The above-mentioned fasteners can be screws or bolts, and all materials are made of stainless steel.

[0021] A filter screen 27 is installed in the pressing chamber 5, and a pressing screw 6 is installed on the filter screen 27. A juice collection hopper 8 is installed below the filter screen 27. The filter screen 27 filters out fruit pulp, and the juice flows into the juice collection hopper 8 through the filter screen 27. The juice collection hopper 8 is connected to a diaphragm pump 21 and a sealed juice collection tank 22 through a juice delivery pipe 7. The diaphragm pump 21 generates negative pressure to draw out the juice and deliver it to the sealed juice collection tank 22.

[0022] The extraction shell 4 is provided with a nitrogen inlet 18, which introduces nitrogen into the extraction shell 4. The position of the nitrogen inlet 18 is set according to the actual situation. During the crushing and pressing stages, nitrogen can be introduced into the working space through the nitrogen inlet 18 to reduce oxidation and improve product quality. The extraction shell 4 is set on the frame 23. Guide wheels 24 and support legs 25 are set below the frame 23. The height of the support legs 25 is adjustable and provides support. The guide wheels 24 make the device move flexibly.

[0023] A conveying motor 14 is provided at the right end of the extraction shell 4. The output shaft of the conveying motor 14 is connected to the conveying screw 12. The left end of the pressing screw 6 is located in the bearing seat of the frame 23. The pressing screw 6, the rotor 26 and the conveying screw 12 are driven to rotate simultaneously by a single conveying motor 14, so as to realize the conveying, crushing, conveying and pressing and slag discharge of the material.

[0024] Working process: Material falls onto the slicing blade assembly 3 through the feed hopper 2. After being incompletely sliced, the material falls into the crushing and conveying chamber 13. Driven by the conveying motor 14, the conveying screw 12, the lower crushing blade 20, the rotor 26, and the pressing screw 6 rotate synchronously. The initially sliced ​​material is conveyed to the crushing chamber 11 by the conveying screw 12. Under the combined action of the upper crushing blade 19 and the lower crushing blade 20, the material is thoroughly crushed into fine particles. During the crushing process, to reduce the oxidation of the material by air, nitrogen is supplied through the nitrogen inlet 18. Nitrogen gas is supplied into the chamber, and the crushed material particles are continued to be transported to the pressing chamber 5 by the rotor 26. Under the conveying of the pressing screw 6, the material particles are squeezed out of juice. During the pressing process, nitrogen gas can continue to be supplied through the nitrogen inlet 18 to continuously reduce oxidation. The material residue is continued to be transported by the pressing screw 6 to the residue outlet pressure plate 17, overcoming the elastic force of the spring 16 and discharged from the discharge outlet. The juice flows into the juice conveying pipe 7 from the juice receiving hopper 8. The juice is sucked out by the negative pressure using the principle of vacuuming by the diaphragm pump 21 and transported to the sealed juice collection tank 22.

[0025] The foregoing has shown and described the basic principles, main features and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this utility model as claimed.
