Description

Technical Field

[0001] The utility model belongs to the technical field of freeze-dried tea powder, and in particular relates to raw material processing equipment for freeze-dried tea powder. Background Art

[0002] The production process of freeze-dried tea powder mainly includes pretreatment, cold extraction, filtration, concentration, freezing and freeze-drying. Among them, cold extraction: the pretreated tea leaves are extracted and mixed with an appropriate amount of low-temperature water. This method is different from the traditional high-temperature extraction method. It can extract the effective ingredients in the tea leaves at a lower temperature, thereby retaining more natural aroma and nutrients.

[0003] After the extraction is completed, the extracted tea liquid needs to be collected and filtered, but the existing extraction devices usually directly mix the tea leaves and the extraction solution for extraction, and use a stirring rod to improve the extraction efficiency. However, this mixing method easily causes the stirring rod to contact and collide with the tea leaves, and then stir the tea leaves into tea residues, which is not conducive to subsequent processing or extended product use, and therefore needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1: Figure 1-6 As shown, a raw material processing equipment for freeze-dried tea powder of the utility model comprises a mounting frame 1 and a mixing tank 11. The mixing tank 11 is elliptical in design. The mixing tank 11 is symmetrically provided with a rotating shaft 12 rotatably connected to the mounting frame 1. The mixing tank 11 is symmetrically provided with a sealing cover 13. Conical disks 14 are symmetrically fixedly provided inside the mixing tank 11. Both of the two conical disks 14 are provided with a plurality of filter holes. A mixing mechanism is installed between the two conical disks 14. The mounting frame 1 is provided with a brake motor 15. The brake motor 15 is transmission-connected to the rotating shaft 12. A connecting rod 16 is fixedly connected in the center of the two conical disks 14.

[0024] When tea leaves are put in, the sealing cover 13 needs to be opened, so that the tea leaves are put into the mixing tank 11 and are located on the conical disk 14. Then, while keeping one sealing cover 13 closed, the extracting liquid is added into the mixing tank 11. After adding a suitable amount, the sealing cover 13 for water inlet is closed so that the inside of the mixing tank 11 is in a closed state. Then, the driving brake motor 15 is rotated to rotate the mixing tank 11 with the rotating shaft 12 as the center of the circle, so that the tea leaves and the extracting liquid are mixed and extracted. After the extraction is completed, the conical disk 14 on the side containing the tea liquid is located on the upper side, and then the sealing cover 13 on the lower side is opened to discharge the extracting liquid. The tea leaves will not be discharged with the extracting liquid due to the obstruction of the upper conical disk 14. When the extracting liquid is discharged, the mixing tank 11 is driven by the brake motor 15 to rotate 180 degrees to open the sealing cover 13 on the upper side. Since the conical disk 14 on the lower side is facing downward at this time, the tea leaves will be discharged from the mixing tank 11 under the action of the inclined surface of the conical disk 14. The mixing mechanism serves to improve the mixing efficiency.

[0025] At the same time, the mixing tank 1 can also be used for the mixed extraction of two kinds of tea, and the tea leaves are not required to be mixed. According to the above operation, different tea leaves are put into the two conical disks 14 through the two sealing covers 13, so that the two kinds of tea leaves can be mixed and extracted at the same time. After completion, the two sealing covers 13 can be opened and discharged respectively. In this way, it is avoided that a single kind of tea needs to be mixed with other tea leaves after extraction. At the same time, different tea leaves can be collected separately to produce different derivative products.

[0026] The utility model can separate tea leaves and extract liquid by setting the conical disk, which is convenient for subsequent processing of the tea leaves and the extract liquid. At the same time, the mixing mechanism is installed inside the two conical disks to avoid direct contact between the tea leaves and the mixing mechanism, which would cause the tea leaves to be subjected to external force and form tea residues that are not conducive to subsequent processing.

[0027] Embodiment 2: Further improvement is made on the basis of Embodiment 1, the mixing mechanism includes a circular plate 20 fixedly connected to the center of the mixing tank 1, the mounting frame 1 is rotatably connected to a driving shaft 21 concentric with the rotating shaft 12, the driving shaft 21 passes through the circular plate 20 and a first bevel tooth 22 is fixedly installed inside the circular plate 20, a second bevel tooth 23 meshing with the first bevel tooth 22 is symmetrically rotatably connected inside the circular plate 20, the two second bevel teeth 23 are fixedly installed with a threaded rod 24, the mixing tank 11 is sealed and slidably connected with a push plate 25 threadedly connected to the threaded rod 24, the side wall of the mixing tank 11 is provided with a connecting groove 26, and the driving shaft 21 is transmission-connected with a driving member.

[0028] A driving member such as a driving motor drives the driving shaft 21 to rotate, thereby driving the first bevel gear 22 and the second bevel gear 23 to rotate. During the rotation of the second bevel gear 23, the threaded rod 24 will be driven to rotate. Since the push plate 25 is threadedly connected to the threaded rod 24 and is slidably connected to the connecting rod, when the threaded rod 24 rotates, it will drive the upper and lower symmetrical push plates 25 to move upward or downward synchronously, thereby promoting the movement of the extraction liquid, so that the extraction liquid is transported to different conical disks 14 through the connecting groove 26, thereby increasing the contact efficiency between the extraction liquid and the tea leaves while cooperating with the rotating mixing tank 11 to improve the extraction efficiency.

[0029] The driving component includes a brake motor 15 which is transmission-connected to the rotating shaft 12. The output end of the brake motor 15 is transmission-connected to the driving shaft 21. The driving shaft 21 is axially slidingly connected with an external spline 27. The rotating shaft 12 is fixedly connected with an internal spline 28 which matches the external spline 27. The external spline 27 is equipped with a telescopic component which matches the mounting frame 1.

[0030] The external spline 27 can only slide axially along the drive shaft 21, so that the drive shaft 21 can drive the external spline 27 to rotate and approach the internal spline 28. When it is necessary to drive the mixing tank 11 to rotate, the telescopic piece is started to move, so that the external spline 27 moves toward the internal spline 28, so that the external spline 27 and the internal spline 28 are interlocked with each other. In this way, when the brake motor 15 rotates, it will drive the drive shaft 21 and the rotating shaft 12 to move at the same time. When the mixing tank 11 does not need to rotate, it only needs to start the telescopic piece to drive the external spline 27 away from the internal spline 28. In this way, the brake motor 15 can only drive the push plate 25 to move up and down.

[0031] A control system can also be installed to electrically connect the control system to the brake motor 15 and the telescopic member, and input a control program to control the brake motor 15 and the telescopic member, so that it is possible to control when the mixing tank 11 rotates and when the push plate 25 pushes the extract and tea leaves to mix.

[0032] The telescopic member includes an electric telescopic rod 29 installed inside the mounting frame 1, and the external spline 27 is rotatably connected to a slide plate slidably connected to the mounting frame, and the slide plate is fixedly connected to a limit rod 30. The electric telescopic rod 29 can be controlled to telescope through an external terminal, thereby driving the external spline 27 to telescopically move along the axial direction of the drive shaft 21, and the drive shaft 21 drives the external spline 27 to rotate inside the slide plate, and the slide plate can only slide under the action of the limit rod 30 and the electric telescopic rod 29.

[0033] A sliding groove 31 is provided on the mixing tank 11 near the driving motor 15, and a sealing plate 32 is fixedly connected to the driving shaft 21 and is sealingly and slidingly connected to the sliding groove 31. The mixing tank 11 is symmetrically provided with water inlets 33 near the circular plate 20, and the mixing tank 11 is symmetrically provided with water outlets 34 connected to the sliding groove 31. Both water inlets 33 are equipped with one-way water inlet valves, and both water outlets 34 are equipped with one-way water outlet valves.

[0034] When the mixing mechanism and the mixing tank 11 work together, the sealing plate 32 blocks the two water inlets 33 and the two water outlets 34, making them unable to communicate. When the external spline 27 moves away from the internal spline 28 driven by the telescopic member, the sealing plate 32 will move away from the water inlet 33 and the water outlet 34. In this way, when the upper push plate 25 exposes the upper water inlet 34, it can enter the sliding groove 31 through the one-way water inlet valve of the water inlet 34, and then enter the lower side of the mixing tank 11 through the one-way water outlet valve of the lower water outlet 34. In this way, when discharging the extract, the upper extract can be discharged from the lower discharge port. At the same time, a filter screen is installed at the connection between the water outlet 34 and the mixing tank 11, so as to control the connection between the water inlet 33 and the water outlet 34 while controlling the rotation of the mixing tank 11.

[0035] The push plate 25 is provided with a protective sleeve 35 matching the threaded rod 24 , and the protective sleeve 35 plays a protective role on the threaded rod 24 .

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
