Description

Technical Field

[0001] The present invention relates to the technical field of vegetable processing, and particularly relates to a freeze-drying device for vegetable blanching and a using method thereof. Background Art

[0002] After vegetable blanching, in order to further inhibit the activities of microorganisms and residual enzymes, retain the nutrients in vegetables to the greatest extent, and also retain the locked color and taste after blanching to the greatest extent, it is usually necessary to freeze-dry the blanched vegetables. In order to facilitate the freeze-drying of the blanched vegetables, workers usually use a freeze-drying device for vegetable blanching. The existing freeze-drying devices for vegetable blanching usually consist of a drying kettle body, a tray placement rack, a vacuum machine, and a condenser.

[0003] For example: The utility model with the application number CN202420978668.2 discloses a deep-processing vacuum freeze-drying kettle, which specifically includes a drying kettle body, an air extraction assembly, and a driving assembly. A partition is fixedly connected inside the drying kettle body, and the partition divides the drying kettle body into a control cavity and a storage cavity. A rotating shaft is rotatably connected to the bottom inner wall of the control cavity, and the top end of the rotating shaft extends into the storage cavity and is fixedly connected to a bottom plate. Two vertical plates are fixedly connected to the upper surface of the bottom plate, and a cross plate is fixedly connected between the two vertical plates. Two sliding rods are fixedly connected to one side of the cross plate, and a storage rack is slidably connected to the outside of the two sliding rods. Four heating tubes are equidistantly installed on the inner side wall of the drying kettle body; compared with the prior art, this application can improve the uniformity of heating of vegetables on the storage rack, thereby improving the drying effect of vegetables.

[0004] However, water-soluble colloids in vegetables (such as pectin, gelatinized starch, etc.) are dissolved and gelatinized due to high temperature during blanching and adhere to the surface of vegetables. These water-soluble colloids will form a colloidal matrix during the freeze-drying process, bonding the vegetables together. After the water sublimes during the freeze-drying process, the remaining colloidal substances will solidify like glue and cause caking, affecting the quality of vegetables and increasing the cost of subsequent processing, making it inconvenient to use. Summary of the Invention

[0005] In view of this, the present invention provides a freeze-drying device and a usage method for vegetable blanching, which has a vibrating slide plate that automatically shakes loose the clumped vegetables when the vegetable tray is taken out. When the vegetable tray is pushed into the tray placement rack, the fixed slider will enter the guiding chute. In the initial state, the guiding inclined plate is pressed against the vibrating slide plate under the action of the reset torsion spring. At this time, the fixed slider will move along the guiding inclined plate, causing the fixed slider to move along the guiding inclined plate to the guiding slide plate, and then the fixed slider will move along the guiding slide plate. The guiding slide plate is a smooth plane, enabling the vegetable tray to smoothly slide into the tray placement rack. When the vegetable tray is completely pushed into the tray placement rack, since the length of the vibrating slide plate is greater than that of the guiding slide plate, the fixed slider will fall from the guiding slide plate onto the vibrating slide plate. After the freeze-drying is completed, as the vegetable tray is pulled out, since the fixed slider is on the vibrating slide plate, the continuous movement of the vegetable tray will cause the fixed slider to continuously pass over the vibration bumps on the vibrating slide plate, causing the fixed slider to vibrate. Furthermore, the vibration is transmitted to the vegetable tray through the vibration of the fixed slider, causing the vegetable tray to vibrate.

[0021] 7. Pull the vegetable tray outwards along the guiding chute. When the fixed slider passes through the vibrating bump on the vibrating slide plate, the tray vibrates.

[0023] Beneficial effects

[0024] When the vegetable tray is pushed into the tray rack, the fixed slider will enter the guiding chute. At this time, the fixed slider will move along the guiding inclined plate, move along the guiding inclined plate to the guiding slide plate, and then move along the guiding slide plate. When the vegetable tray is completely pushed into the tray rack, since the length of the vibrating slide plate is greater than that of the guiding slide plate, the fixed slider will fall from the guiding slide plate onto the vibrating slide plate. After freeze-drying is completed, as the vegetable tray is pulled out, because the fixed slider is on the vibrating slide plate, the continuous movement of the vegetable tray will cause the fixed slider to continuously pass over the vibration bumps on the vibrating slide plate, causing the vegetable tray to vibrate, gently shaking off the vegetables adhering to the vegetable tray, facilitating the removal of the vegetables. At the same time, the vibration of the vegetable tray can disperse the agglomerated vegetables after freeze-drying, making the vegetables looser and more uniform, more convenient for subsequent weighing and packaging, and also reducing quality problems caused by agglomeration, effectively improving the practicality of the freeze-drying device for vegetable blanching and making it more convenient to use.

[0025] By starting the drive motor, the drive motor drives the first pulley to rotate. As the first pulley rotates, the second pulley will be driven to rotate through the transmission belt. As the second pulley rotates, the drive shaft will be driven to rotate. As the drive shaft rotates, multiple groups of tray racks will be driven to rotate, making the vegetable drying more uniform, avoiding local differences, improving the drying uniformity and the quality of the finished product. At the same time, it will accelerate the drying speed, shorten the overall time-consuming, and effectively improve the convenience of the freeze-drying device for vegetable blanching.

[0056] Specific usage method and function of this embodiment: In the present invention, the setting of the operation door 101 enables the convenient placement of the vegetable tray 112 into the vacuum freeze-drying kettle main body 1 for freeze-drying. The setting of the inspection window 102 enables the staff to conveniently observe the drying condition of the vegetables on the vegetable tray 112. The setting of the vacuum machine main body 103 can create and maintain a vacuum environment inside the vacuum freeze-drying kettle main body 1, accelerating the sublimation rate of moisture. The setting of the condenser main body 104 can capture the sublimated water vapor, reduce the load of the vacuum machine main body 103, and maintain vacuum stability. Furthermore, through the cooperation of the vacuum machine main body 103 and the condenser main body 104, the vegetables are freeze-dried. When freeze-drying the vegetables, the vegetables are evenly spread on the vegetable tray 112, and then the vegetable tray 112 is pushed into the tray placement rack 111 through the auxiliary baffle 114. The setting of the pulley rack 115 enables the convenient access of the vegetable tray 112. When the vegetable tray 112 is pushed into the tray placement rack 111, it will cause the vegetable tray 112 to push the control slide plate 116. After the control slide plate 116 is pushed, it will slide inside the tray placement rack 111 and compress the return spring 117. As the return spring 117 slides, it will also drive the control slider 118 to move. During the movement of the control slider 118, it will drive the control wedge block 119 to move. As the control wedge block 119 moves, it will squeeze the auxiliary wedge block 122. After the auxiliary wedge block 122 is squeezed, it will drive the control carriage 120 to move downward and compress the connecting spring 123. The setting of the control chute 121 enables the control slider 118 to pass through conveniently, so that the control slider 118 limits the control carriage 120. The setting of the connecting spring 123 facilitates the reset of the control slide plate 116 after the vegetable tray 112 is taken out. During the movement of the control carriage 120, it will drive the control connecting rod 124 to swing. As the control connecting rod 124 swings, it will drive the control slide rod 125 to move, causing the control slide rod 125 to slide inside the tray placement rack 111. During the sliding of the control slide rod 125, it will drive the control rack 126 to move. As the control rack 126 moves, it will drive the engaged control gear 128 to rotate. As the control gear 128 rotates, it will drive the limit baffle 127 to flip, so that the limit baffle 127 blocks the notch of the tray placement rack 111, preventing the vegetable tray 112 from falling out of the tray placement rack 111. During the flipping of the limit baffle 127, the fixed wedge block 129 will gradually approach the locking bracket 130, causing the locking bracket 130 to squeeze the fixed wedge block 129. After the fixed wedge block 129 is squeezed, the fixed wedge block 129 will slide inside the limit baffle 127 and compress the fixed spring 141. When the limit baffle 127 is completely flipped, at this time, the fixed wedge block 129 just aligns with the notch of the locking bracket 130. At this time, the fixed wedge block 129 will reset with the rebound of the fixed spring 141, causing the fixed wedge block 129 to insert into the locking bracket 130.Fix the position of the limit baffle 127. After the freeze-drying of vegetables is completed, simply press down the connecting plate 133 to drive the auxiliary sliding frame 132 to move downward and compress the auxiliary spring 134. As the auxiliary sliding frame 132 moves, it will squeeze the fixed wedge 129, causing the fixed wedge 129 to slide within the limit baffle 127 and compress the fixed spring 141, so that the fixed wedge 129 disengages from the locking bracket 130. At this time, the limit of the limit baffle 127 is released, and the staff can remove the vegetable tray 112. When the vegetable tray 112 is pushed into the tray placement rack 111, the fixed slider 113 will enter the guiding chute 135. In the initial state, the guiding inclined plate 139 is pressed against the vibrating slide plate 137 under the action of the reset torsion spring 140. At this time, the fixed slider 113 will move along the guiding inclined plate 139, causing the fixed slider 113 to move along the guiding inclined plate 139 to the guiding slide plate 136, and then the fixed slider 113 will move along the guiding slide plate 136. Since the guiding slide plate 136 is a smooth plane, the vegetable tray 112 can smoothly slide into the tray placement rack 111. When the vegetable tray 112 is completely pushed into the tray placement rack 111, since the length of the vibrating slide plate 137 is greater than that of the guiding slide plate 136, the fixed slider 113 will fall from the guiding slide plate 136 onto the vibrating slide plate 137. After the freeze-drying is completed, as the vegetable tray 112 is pulled out, since the fixed slider 113 is on the vibrating slide plate 137, the movement of the vegetable tray 112 will cause the fixed slider 113 to continuously pass over the vibrating bumps 138 on the vibrating slide plate 137, causing the fixed slider 113 to vibrate. Then, through the vibration of the fixed slider 113, the vibration is transmitted to the vegetable tray 112, causing the vegetable tray 112 to vibrate, forming an energy-saving agricultural product drying machine.

Open the operation door, then hold the vegetable tray by hand, align the bottom fixed slider with the guiding chute of the tray placing rack, and smoothly push the tray along the direction of the auxiliary baffle.

2. When the vegetable tray is pushed in, the bottom fixed slider first slides onto the guiding slide plate along the guiding inclined plate. After being completely pushed in, the fixed slider falls into the vibrating slide plate.

3. The tray pushes the control slide plate to slide, compresses the return spring, the control slider drives the control wedge block to squeeze the auxiliary wedge block, the control carriage moves downward, pulls the control lever through the control connecting rod, the control rack moves, meshes with the control gear, makes the limit baffle flip to the notch of the tray placing rack to block the tray from falling off. After the limit baffle flips in place, the fixed wedge block is clamped into the locking bracket under the action of the fixed spring to complete the locking.

4. Close the operation door, then start the vacuum machine main body to extract the air in the kettle and create a vacuum environment (to accelerate the sublimation of moisture); synchronously start the condenser main body to capture the sublimated water vapor and maintain the vacuum stability. Start the driving motor, drive the driving shaft to rotate through the first belt pulley, the second belt pulley and the transmission belt, and the tray placing rack rotates annularly accordingly.

5. After drying is completed, first turn off the driving motor, then turn off the vacuum machine main body and the condenser main body in sequence. After the pressure in the kettle returns to normal pressure, prepare to open the door.

6. Open the operation door, manually press down the connecting plate, drive the auxiliary carriage to squeeze the auxiliary spring, push the fixed wedge block to compress the fixed spring, so that it disengages from the locking bracket, and the limit baffle automatically flips under the meshing action of the control gear and the control rack, exposing the notch of the tray placing rack.

7. Pull the vegetable tray outwards along the guiding chute. When the fixed slider passes through the vibrating bump on the vibrating slide plate, the tray vibrates.

8. After taking out the tray, wipe the inner wall of the main body of the vacuum freeze-drying kettle and remove the scattered vegetable debris.
