Description

Technical Field

[0001] The invention belongs to the technical field of candy preparation, and in particular relates to processing equipment and a preparation method of freeze-dried candy. Background Art

[0002] Freeze-dried candy is a kind of candy made by freeze-drying technology, which is done by quickly freezing the candy at low temperature and then removing the moisture in a vacuum environment so that the candy maintains a crisp taste and original nutritional ingredients.

[0003] In the prior art, the manufacturing process of freeze-dried candy mainly includes two steps: pre-freezing and vacuum drying. First, the candy is frozen to below the freezing point, and then dried in a vacuum environment, so that the water is directly sublimated from the solid state to the gaseous state, thereby removing the water in the candy and achieving the purpose of drying. This process not only retains the nutrition and flavor of the candy, but also gives it a unique crisp taste. In the preparation process of candy, it is often necessary to add white sugar to make the candy first, and the preparation of white sugar mostly adopts the existing conventional two-step method, but the above-mentioned processing technology cannot produce brown sugar, so domestic sugar production enterprises usually use a one-step production method, and no raw sugar is produced during the production process. Instead, the squeezed cane juice is processed through multiple processes such as sulfite purification (or purification by other methods), pre-ashing and heating processes, sulfur fumigation neutralization of cane juice, sedimentation of cane juice, and filtration of cane juice. After the purification process, the cane juice is concentrated and crystallized to become white sugar, and then white sugar or other raw materials are used to add ingredients with certain effects to prepare candy with certain effects.

[0004] When using the above-mentioned white sugar to prepare candies, there are certain disadvantages: for example, there will be residual additives in the traditional sugar-making process, which will affect the molding of white sugar, resulting in poor quality of the candies prepared later, and when using sugarcane to prepare white sugar, certain active substances in the sugarcane will be destroyed due to high temperature or certain additives, affecting the efficacy of the candies. In addition, for the production and preparation process of freeze-dried candies, when the material is transformed from liquid to solid candy, it is necessary to shape the ice drops. In this process, after the material is placed in the mold, the conveyor belt will be used to output the mold and the material to the outside. The placement of the mold and the injection of the material will be affected by the conveying speed of the conveyor belt, which may cause the material and the mold to be unstable, resulting in material waste, affecting the work progress, and failing to meet the production and processing needs. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned candy preparation process, the present invention proposes a freeze-dried candy processing equipment and preparation method with reasonable design, simple structure, convenient processing, and the ability to realize convenient preparation of candies, ensure the quality of candy molding, and improve its efficacy.

[0092] The candy prepared by the process of freeze-dried candy provided by the present invention has the effect of clearing the throat and moistening the throat. The processing technology abandons the traditional sugar-making process, eliminates the residual additives in the sugar-making process, retains the nutritional components of the original flavor of sugarcane juice, and adds one or more freeze-dried concentrated powders of apple, pear and mint, honey, licorice, sterculia lychnophora, honeysuckle, monk fruit, chrysanthemum and tangerine peel. The freeze-dried candy is prepared by low-temperature freeze-drying technology. The candy is delicious and does not cause internal heat, melts in the mouth, and has the effects of clearing away heat, promoting body fluid, and clearing heat and relieving throat.

[0093] Sugarcane has the effect of curing lung heat and cough, clearing away heat and detoxifying, but the raw sugar no longer has this effect. This may be related to the destruction of certain active substances in sugarcane by high temperature or certain additives. Freeze-drying technology can well retain this effect of sugarcane. At the same time, apples and pears have good effects of clearing heat and promoting salivation. Honey, mint, licorice, sterculia lychnophora, honeysuckle, monk fruit, chrysanthemum and tangerine peel all have the effect of clearing the throat and moisturizing the throat. Freeze-dried candy can be prepared through reasonable proportions.

[0094] The candy prepared as described above can make the candy melt in the mouth, clear the throat more quickly and effectively, ensure the throat is refreshed, delicious and not irritating, and when preparing the freeze-dried candy, apples and pears are also used as main ingredients, which reduces the intake of sugar and prevents obesity caused by excessive sugar intake.

Specifically, the pulley 39 is stably set up in the placement frame 38, the purpose is to ensure the smoothness of the driving slide during movement. When in use, the telescopic cylinder 311 is controlled to operate. When the telescopic cylinder 311 contracts, the driving rack 37 engages with the driving gear 310, thereby driving the driving rod 36 to rotate, thereby acting on the on-off rod 62, making it in a conducting or disconnected state. The telescopic cylinder 311 is controlled to operate again to extend it, and the driving rod 36 will drive the on-off rod 62 to rotate in the opposite direction and change to another state, that is, disconnection or conduction. The specific operation can be freely set up according to different usage requirements to ensure the smooth opening and closing of the on-off mechanism 6 and improve the working process.

In this way, when the turntable 71 rotates, it can ensure that each No matter where the support plate 74 is in the vertical direction, it is in a vertical state to ensure stability. It needs to be further explained that when the big head of the eccentric wheel 28 rotates from the bottom to the top, it will drive the feeding assembly to rise. When and only when the big head of the eccentric wheel 28 rotates from the top to the bottom, the feeding assembly drops to the lowest position, and a support plate 74 is just below the feeding assembly. After the material is put in, the lifting and adjusting assembly 2 continues to operate. When the big head of the eccentric wheel 28 reaches the top, the gap between the two adjacent support plates 74 of the loading rack 7 corresponds to the bottom of the feeding assembly, and then continues to operate.

This reciprocating process can not only realize the convenient placement of materials, but also ensure the continuous operation of production and processing work, improve the work progress, and meet the use requirements.

[0100] In order to facilitate the convenient placement of the mold carrier 8, it is necessary to further explain that: there are two pick-up and placement components 14 on the same side, which are mainly used to adapt to mold carriers 8 of different lengths. The two pick-up and placement components 14 on the same side are a group and two groups are set up. The pick-up and placement components 14 connected to the drive of the ejection mechanism 15 are mainly used to take and place the mold carrier 8 carrying materials, that is, after clamping the mold carrier 8 located at the bottom of the material carrier 7, it is transported outward to the next processing step to ensure the effective progress of the production and processing work. The other group of pick-up and placement components 14 is mainly used to clamp the mold carrier 8 on the outside, and then move toward the position close to the bottom of the material carrier 7 while the previous group of pick-up and placement components 14 is led outward, and the empty mold carrier 8 is placed on the loading rack.

Of course, the use functions of the two groups of pick-and-place assemblies 14 are different. The difference lies in the order of picking up and placing the mold carrier 8. For the transverse moving plate 125 and the transverse sliding bar 124, they can be moved and adjusted in the transverse direction to drive the vertical The lateral adjustment of the driving cylinder 13 and the pick-and-place assembly 14 when they are in the outer position is used to take out the empty mold carrier 8 or place the mold carrier 8 loaded with materials. As for the vertical driving cylinder 13, the purpose is to adjust the vertical position of the pick-and-place assembly 14 to ensure the effective implementation of the clamping action. Further, under the action of the longitudinal moving assembly 12, the pick-and-place assembly 14 is driven to move. When taking materials, the pick-and-place assembly 14 approaches and uses its movement to act on the ejecting mechanism 15 to eject the mold carrier 8, and then the clamping work is carried out. Subsequently, the pick-and-place assembly 14 is led out to the outside. At the same time, another set of pick-and-place assemblies 14 take the empty mold carrier 8 at the external process and move it to the carrier 7.After the workpiece is released, it is placed on the carrier 7, and this reciprocating process is carried out to realize the corresponding processing steps, improve the work progress, and meet the use requirements.

A limit rod 149 is set on the slider 143 corresponding to the longitudinal sliding groove 1481 and the Z-shaped groove 1482. The specific description is as follows: for the established taking For the placing assembly 14, its output end can realize variable-length telescopic movement, that is to say: in order to realize the clamping of the mold carrier plate 8 at multiple points to ensure its stability during the clamping process, the longitudinal moving assembly 12 and the vertical driving cylinder 13 are first used to adjust the position of the placing assembly 14. During the adjustment process, the longitudinal driving cylinder 1410 is controlled to operate to move the movable trapezoidal plate 148 outward, and the finger cylinder 145 is restricted by the sliding rod 142 and the sliding block 143. At the same time, it will also be restricted by the limiting rod 149 and the longitudinal sliding groove 1481 and the Z-shaped groove 1482 while moving horizontally. The limit of time moves in the longitudinal direction until it reaches the farthest position. At this time, the driving of the longitudinal moving component 12 is still in progress, and the clamping plate 146 is brought close to the T-shaped rod 82, which provides convenient conditions for the subsequent clamping of the mold carrier 8 and meets the use requirements. When the mold carrier 8 is clamped and output outward, the position of each finger cylinder 145 is maintained. After the mold carrier 8 and the material are exported, the pick-and-place component 14 can be retracted to prevent the occurrence of limitation during the operation and movement, and then repeat the above process. This reciprocating process improves the functionality of the device and meets the use requirements.

[0102] In order to realize the convenient export of the mold carrier plate 8 containing the material, that is, to provide convenience for the pick-and-place component 14 to clamp it and ensure the working process, the ejection mechanism 15 includes a stand 151, and a limit wheel 152 is arranged in the stand 151 to improve the smoothness of the longitudinal rack 153 during the movement and adjustment process.
