Description

Technical Field

[0001] This utility model relates to the field of dried fruit pressing and extraction technology, and in particular to a dried fruit pressing and extraction device. Background Technology

[0002] In today's food processing and oil extraction industry, dried fruit pressing and extraction equipment plays a crucial role. With the increasing demand for healthy oils, the process of extracting oil from dried fruits with high oil content, such as walnuts, camellia seeds, and flax seeds, has attracted much attention. These dried fruits are rich in nutrients, and their oils have high nutritional and economic value. Most dried fruit pressing equipment on the market uses mechanical force to squeeze the dried fruits, separating the oil from them. For example, the common screw oil press uses the change in the screw's spiral lead and the increase in the bottom diameter to create pressure in the pressing chamber, squeezing the dried fruits and causing the oil to flow out from the gaps in the pressing cage. The remaining dried fruit residue is discharged from the cake outlet.

[0003] The existing fruit presses do not discharge the dried fruit residue in a timely manner. During continuous operation, if the continuously pressed dried fruit residue cannot be discharged quickly, it will gradually accumulate inside the device. This accumulated residue not only takes up space, but also gradually blocks the oil discharge channel as its quantity increases. Once the oil discharge channel is blocked, the oil cannot flow out smoothly, which will reduce the oil extraction efficiency and affect the production progress. On the other hand, it may also cause abnormal pressure increases inside the device, damaging the equipment, increasing the risk of equipment failure and maintenance costs, and seriously affecting the normal operation of the entire dried fruit pressing and extraction process. Utility Model Content

[0004] In order to overcome the problem that existing dried fruit pressing devices cause the dried fruit residue to accumulate and block the oil discharge channel due to the untimely discharge of dried fruit residue, this utility model provides a dried fruit pressing and extraction device.

[0005] The technical solution is as follows: A dried fruit pressing and extraction device includes a dried fruit oil pressing component, a residue discharge component, a geared motor, and an oil collection hopper; the two ends of the dried fruit oil pressing component are respectively equipped with a residue discharge component and a geared motor; the lower end of the dried fruit oil pressing component is equipped with an oil collection hopper; the dried fruit oil pressing component includes a pressing pipe, a conical oil pressing screw, and an oil pressing trough; the residue discharge component includes a residue pipe, a spring, a ball bearing, a residue discharge plate, a residue discharge hole, and a residue hopper; the inside of the pressing pipe is equipped with a conical oil pressing screw; one end of the pressing pipe is equipped with a residue pipe, and the residue pipe is connected to the pressing pipe through a flange.

[0006] Furthermore, a spring is installed inside the slag pipe; ball bearings and a slag discharge plate are respectively installed at both ends of the spring, and the slag discharge plate is installed on the side close to the pressing pipe.

[0007] Furthermore, the inside of the slag discharge plate is provided with slag discharge holes around its shaft hole, and the slag discharge holes are set horizontally through the slag discharge plate.

[0008] Furthermore, the ball bearing is rotatably connected to the tapered oil press screw bearing, and the ball bearing's shaft housing is rotatably connected to the slag pipe bearing.

[0009] Furthermore, the output end of the geared motor is connected to the conical oil pressing screw drive; a feeding hopper is provided at the upper end of the pressing pipe, and the feeding hopper is located on the side close to the geared motor.

[0010] Furthermore, an oil pressing groove is provided on the lower end face of the pressing tube, and the oil pressing groove is located below the side where the blades of the conical oil pressing screw gradually decrease.

[0011] Furthermore, an oil collection hopper is provided below the oil pressing trough, and the input end of the oil collection hopper is sealed to the pressing pipe.

[0012] The beneficial effects are as follows: This utility model drives a conical oil press screw to rotate via a geared motor. As the diameter of the spiral blades of the conical oil press screw gradually decreases from one side of the geared motor to the side of the residue discharge assembly, the dried fruit fed into the pressing tube from the feeding hopper is spirally transported to the oil pressing trough. Due to the gradual spiral rotation and compression of the dried fruit by the spiral blades of the conical oil press screw, the pressure on the dried fruit gradually increases. Under extreme pressure, the dried fruit is crushed and pressed to extract dried fruit oil. The pressed oil from the dried fruit is discharged downwards from the oil pressing trough into the oil collection hopper for collection, while the pressed dried fruit residue continues to be compressed and advanced towards the residue discharge assembly. Utilizing the setting of the residue discharge hole of the residue discharge plate, the dried fruit residue is squeezed into the residue discharge hole under pressure. The dried fruit residue discharged from the residue discharge hole falls into the residue hopper for collection, improving the convenience of dried fruit residue discharge and collection, eliminating the need for manual discharge of dried fruit residue, and improving the efficiency of subsequent external discharge and separation processing of dried fruit pressed oil.

[0013] The spring is used to hold the slag discharge plate in place, improving the contact stability between the slag discharge plate and the conical oil press screw. Furthermore, the soft connection of the spring makes it easier to disassemble the slag discharge plate, thus improving the ease of disassembly and cleaning. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-5 As shown, the dried fruit pressing and extraction device includes a dried fruit oil pressing component 1, and also includes a residue discharge component 2, a geared motor 3, and an oil collection hopper 4. The residue discharge component 2 and the geared motor 3 are respectively installed at both ends of the dried fruit oil pressing component 1. The oil collection hopper 4 is installed at the lower end of the dried fruit oil pressing component 1. The dried fruit oil pressing component 1 includes a pressing pipe 101, a conical oil pressing screw 102, and an oil pressing trough 103. The residue discharge component 2 includes a residue pipe 201, a spring 202, a ball bearing 203, a residue discharge plate 204, a residue discharge hole 205, and a residue hopper 206. The conical oil pressing screw 102 is installed inside the pressing pipe 101. The residue pipe 201 is installed at one end of the pressing pipe 101, and the residue pipe 201 is connected to the pressing pipe 101 by a flange.

[0023] A spring 202 is installed inside the slag pipe 201; a ball bearing 203 and a slag discharge plate 204 are respectively installed at both ends of the spring 202, and the slag discharge plate 204 is installed on the side close to the pressing pipe 101.

[0024] The slag discharge plate 204 has slag discharge holes 205 arranged around its shaft hole, and the slag discharge holes 205 are arranged horizontally through the slag discharge plate 204.

[0025] The ball bearing 203 is rotatably connected to the bearing of the conical oil press screw 102, and the outer shell of the ball bearing 203 is rotatably connected to the bearing of the slag pipe 201.

[0026] The output end of the geared motor 3 is connected to the conical oil pressing screw 102 for transmission; the upper end of the pressing pipe 101 is provided with a feeding hopper 104, and the feeding hopper 104 is located on the side close to the geared motor 3.

[0027] The lower end face of the pressing tube 101 is provided with an oil pressing groove 103, and the oil pressing groove 103 is located below the side where the blades of the conical oil pressing screw 102 gradually decrease.

[0028] The conical oil press screw 102 is driven to rotate by the geared motor 3. As the diameter of the spiral blades of the conical oil press screw 102 gradually decreases from one side of the geared motor 3 to the side of the residue discharge assembly 2, the dried fruit fed into the pressing tube 101 from the feeding hopper 104 is spirally transported to the oil pressing tank 103. Due to the gradual spiral rotation and compression of the dried fruit by the spiral blades of the conical oil press screw 102, the pressure on the dried fruit gradually increases. Under extreme pressure, the dried fruit is crushed and pressed to extract dried fruit oil. The pressed oil from the dried fruit is discharged downward from the oil pressing trough 103 into the oil collecting hopper 4 for collection, while the pressed dried fruit residue continues to be compressed and advanced towards the residue discharge component 2. With the setting of the residue discharge hole 205 of the residue discharge plate 204, the dried fruit residue is squeezed into the residue discharge hole 205 under pressure. The dried fruit residue discharged from the residue discharge hole 205 falls into the residue hopper 206 for collection, which improves the convenience of dried fruit residue discharge and collection, eliminates the need for manual discharge of dried fruit residue, and improves the efficiency of subsequent discharge separation and processing of dried fruit pressed oil.

[0029] With the spring 202 in place, the spring 202 is used to hold the slag discharge plate 204 against it, thereby improving the contact stability between the slag discharge plate 204 and the conical oil pressing screw 102. Furthermore, due to the soft connection of the spring 202, the slag discharge plate 204 is easier to disassemble, thus improving the ease of disassembly and cleaning of the slag discharge plate 204.

[0030] Example 2

[0031] Based on Example 1, such as Figures 1-5 As shown, an oil pressing collection hopper 4 is provided below the oil pressing trough 103, and the input end of the oil pressing collection hopper 4 is sealed to the pressing pipe 101.

[0032] The oil collection hopper 4 is used to collect the dried fruit pressed oil discharged from the oil pressing tank 103, thereby facilitating the collection of dried fruit pressed oil and solving the problem of oil leakage during collection.
