[0002] Sugar alcohols are mostly presented in the form of crystals or particles of different particle sizes. Since the national standard requires that the moisture content of sugar alcohols be less than 1%, and the moisture content of some sugar alcohols, such as maltitol and erythritol, is lower than this standard value, when these low-moisture sugar alcohols are used in compressed candies, there will be a problem of insufficient viscosity between the materials, and the compressibility of the compressed candies is low. In view of this, humidification equipment is required to humidify the above-mentioned sugar alcohols to ensure that their moisture content is greater than a predetermined value to meet the compressibility of the compressed candies.

[0022] Schematic diagram of powder humidification equipment with pre-wetting device, mainly used for humidifying sugar alcohol, reference Figures 1 to 3 According to a preferred embodiment of the present invention, a powder humidifying device with a pre-wetting device includes an initial wetting device 10, and the initial wetting device 10 includes a box 101, a pre-wetting device 102 and a stirring component 103.

[0023] Specifically, if Figure 2 As shown, the box body 101 has a first stirring chamber 1011. It should be noted that the first stirring chamber 1011 has a flat bottom.

[0024] In addition, if Figure 2 As shown, the pre-wetting device 102 includes a two-stage lifting drive device 1021, a lifting plate assembly 1022, and a plurality of insert cylinders 1023. The sidewalls of each insert cylinder 1023 are provided with a plurality of first high-pressure atomizing nozzles 10231. The insert cylinder 1023 is mounted on the lifting plate assembly 1022. The two ends of the two-stage lifting drive device 1021 are respectively fixedly connected to the box 101 and the lifting plate assembly 1022. It should be noted that when the material is placed in the first stirring chamber 1011, the insert cylinder 1023 is inserted into the material, and the first high-pressure atomizing nozzle 10231 sprays water mist to achieve pre-wetting of the material in a stacked and static state.

[0025] In addition, if Figure 2As shown, the stirring assembly 103 is located in the first stirring cavity 1011 and below the pre-wetting device 102, the stirring assembly 103 comprises a rotating driving device 1031, a rotating shaft 1032, a plurality of bottom scraping blades 1033, a plurality of upper wall scraping blades 1034, a plurality of connecting rods 1035 and a lifting rod 1036, the rotating driving device 1031 is fixedly installed on the box body 101 and connected with the rotating shaft 1032, one end of the rotating shaft 1032 away from the rotating driving device 1031 extends into the first stirring cavity 1011, and the bottom end of the rotating shaft 1032 is fixedly connected with the bottom scraping blades 1033 arranged in an annular array, one end of the upper wall scraping blade 1034 is rotatably installed in the through groove 10321, the other end of the upper wall scraping blade 1034 has a bent wall- abutting portion 10341, the connecting rod 1035 corresponds to the upper wall scraping blade 1034 one-to-one, and the two ends of each connecting rod 1035 are rotatably connected with the bottom of the lifting rod 1036 and the corresponding upper wall scraping blade 1034, respectively, and the top of the lifting rod 1036 is rotatably connected with the lifting plate assembly 1022 and moves up and down with the lifting plate assembly 1022. It should be noted that the bottom scraping blades 1033 are used to stir the material at the bottom of the first stirring cavity 1011, and the upper wall scraping blades 1034 are used to stir the material at a higher position of the first stirring cavity 1011 and the material on the side wall.

[0026] The working principle of the pre-wetting device 10 will be further described as follows: in the initial state, referring to Figure 2 , the lifting plate assembly 1022 is located at the high point of the first stirring cavity 1011, at this time, since the lifting rod 1036 is connected with the lifting plate assembly 1022, the lifting rod 1036 also extends out of the top of the rotating shaft 1032 by a predetermined distance, and as the lifting rod 1036 moves upward, the connecting rod 1035 moves with it, and the upper wall scraping blade 1034 is unfolded, and the end of the upper wall scraping blade 1034, i.e. the wall- abutting portion 10341, is attached to the side wall of the first stirring cavity 1011, at this time, the operator can pour the material into the first stirring cavity 1011, and when the material pile covers to the position where the upper wall scraping blade 1034 is flush, stop further pouring, referring to Figure 3, make the secondary lifting drive device 1021 move downward, and make the insertion cylinder 1023 be inserted into the material, and then make the first high-pressure atomizing nozzle 10231 spray atomized water vapor to humidify the material close to the insertion cylinder 1023. It should also be pointed out that when the secondary lifting drive device 1021 moves downward, the upper wall scraping blade 1034 will rotate toward the bottom scraping blade 1033 by a predetermined angle and retract, and the material can be stirred once at this time; it should be emphasized that the significance of inserting the insertion cylinder 1023 into the static material is that, when the stirring component 103 is not stirred, if the first high-pressure atomizing nozzle 10231 is only located above the material, it can only humidify the top layer of the material, and by inserting the insertion cylinder 1023 into the material, the material can be pre-humidified more fully; after pre-humidification, refer to Figure 2 , so that the secondary lifting drive device 1021 moves upward, and the end of the upper scraping blade 1034 is fitted with the side wall of the first stirring chamber 1011. At this time, the rotation drive device 1031 is activated, and the rotation of the rotating shaft 1032 will drive the bottom scraping blade 1033 and the upper scraping blade 1034 to follow the circumferential rotation, and make the material tumble. At the same time, the first high-pressure atomizing nozzle 10231 located above the material sprays water mist again to preliminarily humidify the tumbling material.

[0027] Furthermore, if Figure 1 As shown, the powder humidifying equipment with a pre-wetting device also includes a fine wetting device 20, which includes a pot body 201, a sliding member 202, two first linear drive devices 203, a base body 204, a second high-pressure atomizing nozzle 205 and a plurality of rotating members 206. The sliding member 202 is slidably arranged on the base body 204 by being connected to a push rod of a second linear drive device 207. The two first linear drive devices 203 are respectively located on both sides of the pot body 201. The pot body 201 has a second stirring chamber 2011. The rotating member 206 is rotatably installed in the width direction of the second stirring chamber 2011, and the second high-pressure atomizing nozzle 205 extends into the second stirring chamber 2011.

[0028] It is to be noted that the pot body 201 is a round-bottomed pot. When the material is humidified to a certain degree in the preliminary humidifying device 10, half of the material is transported into the fine humidifying device 20, while the preliminary humidifying device 10 further stirs and humidifies the other half of the material. When the fine humidifying device 20 is filled with half of the material, the slide 202 is actuated while the push rod on the first linear driving device 203 is extended by a predetermined distance, thereby simulating the action of "turning over the pot" to make the material in the second stirring cavity 2011 roll up and down and be re-humidified by the second high-pressure atomizing nozzle 205, so as to ensure that each granular material can absorb a predetermined amount of water. The specific "turning over the pot" action is as follows: when the slide 202 slides in the right direction as shown in the figure, the push rod on the linear driving device at the left side of the pot body 201 extends outward by a predetermined length, and the pot body 201 is tilted by a predetermined angle in the clockwise direction, and the pot opening of the pot body 201 is inclined to the right side. Then, the push rod on the first linear driving device 203 at the left side of the pot body 201 is retracted inward by a predetermined length, and the push rod on the first linear driving device 203 at the right side of the pot body 201 extends outward by a predetermined length, so that the pot body 201 is tilted by a predetermined angle in the counterclockwise direction, and the pot body 201 is inclined to the left side. Then, the slide 202 is further slid in the left direction to complete one "turning over the pot" action. By repeatedly performing the above steps, the material in the second stirring cavity 2011 is rolled up and down, and the second high-pressure atomizing nozzle 205 fully humidifies the material. When the fine humidifying device 20 humidifies the half of the material to a predetermined humidity and discharges the material, the other half of the material is humidified for a longer time in the preliminary humidifying device 10, so that the discharge or the shorter time humidification in the fine humidifying device 20 can be selected as needed. It is easy to see that, compared with the prior art, the present application has the advantage of more uniform humidity humidification of the material. In addition, the pre-humidifying device 102 has another function of selectively expanding the upper wall scraping paddle 1034 to avoid interference with the movement of the insertion cylinder 1023 when the insertion cylinder 1023 is inserted into the material.

[0029] Further, in order to avoid the interference between the upper wall scraping paddle 1034 and the insertion cylinder 1023 during the turning process, the insertion cylinder 1023 is provided with a Figure 3As shown, the lifting plate assembly 1022 comprises a first plate body 10221 and a second plate body 10222, the second plate body 10222 is located above the first plate body 10221, a plurality of insertion barrels 1023 arranged in a ring array are arranged on the first plate body 10221 and the second plate body 10222, the insertion barrels 1023 on the second plate body 10222 are slidably arranged in the height direction through the first plate body 10221, the insertion barrels 1023 on the second plate body 10222 are located outside the insertion barrels 1023 on the first plate body 10221, and the length of the insertion barrels 1023 from outside to inside gradually decreases.

[0030] It should be noted that by making the length of the insertion barrels 1023 on the outside longer and the length of the insertion barrels 1023 close to the upper scraping wall paddle 1034 shorter, the insertion barrels 1023 can be inserted deeper into the material and humidify more material as much as possible while avoiding the interference between the upper scraping wall paddle 1034 and the insertion barrels 1023.

[0031] Further, in order to achieve that the insertion barrels 1023 on the outside can move faster than the insertion barrels 1023 on the inside when withdrawing from and extending into the material in the same time, as shown in the figure, Figure 2 or Figure 3 As shown, the secondary lifting driving device 1021 comprises a first cylinder body 10211, a second cylinder body 10212, an extension piece 10213 and a piston rod 10214, the outer wall of the second cylinder body 10212 has a piston part 102121, the first cylinder body 10211 has a first oil cavity (not marked in the figure), the piston part 102121 of the second cylinder body 10212 divides the first oil cavity into a first upper oil cavity and a first lower oil cavity, the second cylinder body 10212 has a second oil cavity (not marked in the figure), one end of the piston rod 10214 is provided with a partition piston 102141, and the partition piston 102141 divides the second oil cavity into a second upper oil cavity and a second lower oil cavity, the other end of the piston rod 10214 extends out of the second cylinder body 10212 and is connected with the second plate body 10222, one end of the extension piece 10213 is fixedly connected with the first cylinder body 10211, the other end of the extension piece 10213 is slidably arranged in the height direction through the second plate body 10222 and is fixedly connected with the first plate body 10221, the cross-sectional shape of the extension piece 10213 is preferably a semi-cylindrical or concave shape, and the first upper oil cavity, the first lower oil cavity, the second upper oil cavity and the second lower oil cavity are each provided with an oil inlet (not marked in the figure).

[0032] It should be noted that when the insertion cylinder 1023 needs to be inserted into the material, oil is injected into the first upper oil chamber and the second upper oil chamber. When the first upper oil chamber is injected with oil, the second cylinder body 10212 itself begins to move downward, and since oil is injected into the second upper oil chamber at the same time, the second plate body 10222 connected to the piston rod 10214 accelerates to move downward, and drives the outer insertion cylinder 1023 to be inserted into the material; similarly, when the insertion cylinder 1023 needs to be withdrawn from the material, oil is injected into the first lower oil chamber and the second lower oil chamber.

[0033] Furthermore, in order to realize that when the lifting plate assembly 1022 moves up and down, the lifting rod 1036 can be driven to move up and down, and at the same time, when the rotating shaft 1032 rotates circumferentially, it does not interfere with the movement of the lifting plate assembly 1022, as shown in FIG. Figure 3 As shown, the second plate 10222 has a ball groove 102221 on one side close to the stirring assembly 103, and the top of the lifting rod 1036 has a ball head 10361, and the ball head 10361 is rotatably arranged in the ball groove 102221, and the radial dimension of the groove of the ball groove 102221 is smaller than the ball diameter of the ball head 10361.

[0034] It should be noted that when the rotating shaft 1032 rotates, the ball head 10361 rotates circumferentially within the ball groove 102221. It should also be noted that the cross-section of the lifting rod 1036 is preferably square, so that when the rotating shaft 1032 rotates, the lifting rod 1036 rotates synchronously, that is, the lifting rod 1036 only moves up and down along the axial direction of the rotating shaft 1032 and cannot rotate relative to the rotating shaft 1032.

[0035] Furthermore, since the bottom scraping blade 1033, the upper scraping blade 1034 and the material will rub against the cavity wall of the first stirring chamber 1011 during tumbling, heat will be generated after a long time. If the material is sugar alcohol, sugar alcohol tends to become sticky at high temperature and change from solid to liquid. In view of this, if Figure 3 As shown, a water cooling channel 1012 arranged in a spiral shape is provided on the side wall of the box body 101 .

[0036] It should be noted that if the water cooling channel 1012 is embedded in the box 101, the material of the box 101 is preferably plastic, and the water cooling channel 1012 is preferably a metal pipe, and the water cooling channel 1012 is embedded in the box 101 by injection molding; if the water cooling channel 1012 is sleeved on the outer wall of the box 101, the metal pipe constituting the water cooling channel 1012 can be sleeved on the outer wall of the box 101 by welding; if the water cooling channel 1012 is embedded in the inner wall of the box 101, the inner wall of the box 101 has a spiral groove, so that the metal pipe constituting the water cooling channel 1012 is embedded in the spiral groove.

[0037] Further, in order to prevent the connecting rod 1035 from being stuck during the up and down movement of the lifting rod 1036, as shown in Figure 3 Each of the upper scraping wall blades 1034 has a sliding groove 10342, and one end of the connecting rod 1035 has a cylindrical pin (not shown in the figure), which is rotatably and slidably inserted into the sliding groove 10342.

[0038] Further, as shown in Figure 3 The preliminary wetting device 10 further comprises a moisture monitoring sensor 104, which is fixedly installed on the box 101 and extends into the first stirring cavity 1011.

[0039] Further, in order to prevent the pot body 201 from shaking in the front and rear directions, as shown in Figure 1 The fine wetting device 20 further comprises two guide plates 208, which are respectively located on the two sides of the pot body 201 in the front and rear directions, and the guide plates 208 are connected with the seat body 204, and the two side edges of the pot body 201 are in point contact with the two guide plates 208.

[0040] In summary, the powder humidifying equipment with a preliminary wetting device according to the embodiments of the present application is illustrated, which provides the advantages of more uniform material humidity humidification and the like for the powder humidifying equipment with a preliminary wetting device.

[0041] It is worth mentioning that in the embodiments of the present application, the powder humidifying equipment with a preliminary wetting device has a simple structure and does not involve complex manufacturing processes and expensive materials, which has high economic efficiency.
