Description

Technical Field

[0001] The present invention relates to the technical field of food additive drying, and particularly to a food additive drying device. Background Art

[0002] Food additives are non-nutritive substances that are consciously added to food in small amounts generally to improve the appearance, flavor, tissue structure or storage properties of food. Some food additives such as vitamins and minerals can supplement the nutrients lacking in food, enhance the nutritional value of food, and meet the human body's demand for nutrients. Food additives can facilitate the processing and production of food, improve production efficiency and reduce costs.

[0003] After retrieval, a Chinese patent with the publication number CN208091160U discloses an automatic food additive drying device, which includes a machine shell, a feeding mechanism fixedly installed on the top of the machine shell, a drying mechanism, a conveying mechanism, a storage mechanism, and a control system. The feeding mechanism includes a feeding port and an opening and closing device for controlling the feeding speed of the feeding port. The opening and closing device includes a baffle and a first driver for driving the baffle to move; the drying mechanism includes a bracket and a plurality of heating plates fixedly connected to the bracket from top to bottom. Heating wires are arranged inside the heating plates; the conveying mechanism includes a plurality of conveyor belts installed at intervals below the heating plates and a plurality of second drivers independently driving the conveyor belts to move. The adjacent conveyor belts move in opposite directions and are installed with left and right offsets. The food additive raw materials are evenly spread on the conveyor belts of the conveying mechanism, and the raw materials are dried by the drying mechanism to realize efficient automatic drying of food additives. However, in actual use, the following deficiencies still exist in this solution:

[0004] In the production and processing of food additives, drying is a crucial link, which is directly related to the quality and stability of the product. Food additives are usually transported through multiple conveyor belts to achieve drying. However, food additives can only be turned over at the joints of multiple conveyor belts. Once they are placed on the conveyor belts, they will remain in a relatively fixed state and are difficult to be further turned or adjusted. This limitation not only leads to uneven heating during the drying process but also greatly reduces the drying efficiency.

[0005] Therefore, the present application provides a food additive drying device to meet the requirements of efficient and rapid drying of food additives. Summary of the Invention

[0055] Advantages of the present invention:

[0056] 1. For this food additive drying equipment, by setting the support structure and the feeding component, during the feeding process, the ingenious combination of the roller pressing plate and the spring telescopic rod before the food additive enters the drying box can not only effectively break the lumps in the material, prevent these lumps from forming drying dead corners in the subsequent drying process and affecting the overall drying effect, but also through the fine spreading of the tooth comb opening, the initial distribution of the food additive on the discharge rack reaches a high degree of uniformity. This uniform distribution not only helps the uniform transfer of heat, ensures that every part of the material can be fully dried, but also greatly reduces the problem of uneven drying caused by material accumulation, thereby improving the overall drying efficiency and quality.

[0057] 2. For this food additive drying equipment, by setting the top plate and the material spreading component, through the rotation and reciprocating sliding of the spreading plate, the lifted food additive is scattered over a large area, increasing the contact area between the material and the drying gas, promoting the rapid transfer of heat and the rapid evaporation of moisture, ensuring that the food additive can be lifted and its distribution can be changed multiple times during the process of being transported and dried in the drying box, and greatly improving the drying efficiency of the food additive in the drying box.

[0058] 3. For this food additive drying equipment, by setting the cross plate and the material pushing component, through the pushing action of the pushing plate, the food additive at the edge is effectively pushed towards the middle position, avoiding the problems of material accumulation and uneven drying at the edge. This pushing action not only ensures the uniform distribution of the material on the discharge rack, but also enables the food additive to be lifted when it continues to be transported. Cooperating with the use of the material spreading component, it avoids the use of multi-stage conveyor belts and ensures that the occupied space of the entire device is smaller.

[0071] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

[0073] like Figures 1 to 9 As shown, a food additive drying device comprises a drying box 1, a discharge rack 2 is arranged inside the drying box 1, a feeding frame 3 is penetrated at one end of the drying box 1, a discharge pipe 4 is penetrated at the bottom surface of the end of the drying box 1 away from the feeding frame 3, baffles 5 are arranged on both sides of the top surface of the discharge rack 2, the baffles 5 are arranged in an inclined manner, a supporting structure is arranged between the discharge rack 2 and the inner bottom surface of the drying box 1, a driving shaft 7 is rotatably installed on the inner side wall of the feeding frame 3, a feeding assembly is arranged inside the feeding frame 3, and the opposite sides of the two baffles 5 are arranged. Several top plates 9 distributed in a linear array are fixedly installed between the two surfaces, and several top plates 9 are provided with material shifting components. Several transverse plates 11 distributed in a linear array are fixedly installed between the opposite sides of the two baffles 5, and several sides of the transverse plates 11 are provided with material pushing components. Lifting ears 13 are fixedly installed at the four corners of the top of the drying box 1; the material discharging rack 2 is used in conjunction with the supporting structure to lift the food additives; the material shifting component is used in conjunction with the material pushing component to scatter and gather the food additives on the material discharging rack 2;

[0074] During use, first, the food additive can be added to the discharge rack 2 in the drying oven 1 through the feeding frame 3. The drying oven 1 is installed through the lifting lugs 13 and is in an inclined state as a whole. When the food additive in the feeding frame 3 passes through the feeding frame 3, it can be rolled and leveled under the action of the feeding component, ensuring that the lumps in the food additive can be broken. When the food additive is added to the discharge rack 2, the discharge rack 2 can vibrate greatly in the drying oven 1 under the support of the support structure. And under the action of vibration, the food additive can move along the discharge rack 2. When the food additive is lifted under the action of vibration, it can be deflected by the deflecting component on the top plate 9 to the baffle 5. The baffle 5 is inclined, so that the food additive can quickly slide to the edge position of the discharge rack 2. At the same time, the food additive after sliding is pushed to the middle position of the discharge rack 2 under the action of the pushing component for deflection again. The whole process makes the contact surface between the food additive and the drying gas in the drying oven 1 larger and the contact time longer, accelerating the drying process of the food additive and improving the drying efficiency. After the food additive is dried, it can be discharged and collected through the discharge pipe 4. The heating working principle and connection method of the drying oven 1 are existing mature technologies and will not be elaborated here.

[0075] As Figure 2 , Figure 3 , Figure 4 shown, the support structure includes: a bracket 61, arranged on the outside of the discharge rack 2, and the four corners of the discharge rack 2 are fixedly connected to the bracket 61; two groups of struts 62, symmetrically and fixedly installed on the top surface of the bracket 61, and the side surface of the baffle 5 is fixedly connected to the top end of the strut 62; four elastic support members 63, respectively arranged at the four corner positions of the bracket 61, and the bottom end of the elastic support member 63 is fixedly connected to the inner bottom surface of the drying oven 1; a driving motor 64, fixedly installed at the center position of the bottom surface of the bracket 61; two flywheels 65, respectively fixedly installed on the two output ends of the driving motor 64;

[0076] When the food additive is added to the discharge rack 2, the driving motor 64 is turned on to drive the two flywheels 65 to rotate at high speed. Under the action of the rotation of the flywheels 65, the bracket 61, the discharge rack 2, etc. can move reciprocally along the elastic support member 63, thereby realizing the vibration of the discharge rack 2. Combined with the inclined setting of the discharge rack 2 and the drying oven 1, the food additive can be lifted during the movement along the discharge rack 2.

[0077] As Figure 5 , Figure 6As shown in the figure, the feeding assembly includes: a plurality of spring telescopic rods 81, which are fixedly installed on the outer wall of the driving shaft 7 in an annular array; a plurality of roller pressing plates 82, which are respectively fixedly installed at the telescopic ends of the plurality of spring telescopic rods 81; a fixed frame 83, which is fixedly installed on the inner side wall of the feeding frame 3, and the fixed frame 83 is flush with the inner bottom surface of the feeding frame 3; a sliding plate 84, which is slidably installed on the inner side wall of the fixed frame 83, and the bottom surface of the sliding plate 84 is attached to the inner bottom surface of the feeding frame 3; a reciprocating lead screw 85, which is rotatably installed on the inner side wall of the fixed frame 83, and the sliding plate 84 is screwed to the reciprocating lead screw 85; a plurality of tooth comb openings 86, which are arranged in a linear array at one end of the sliding plate 84 away from the fixed frame 83; a driving motor two 87, which is fixedly installed on the side surface of the feeding frame 3, and the output end of the driving motor two 87 is fixedly connected to the driving shaft 7;

[0078] When food additives are added to the feeding frame 3, the feeding frame 3 is inclined. Therefore, the food additives can slide along the inner bottom surface of the feeding frame 3 under the action of gravity. At this time, the driving motor two 87 is started to drive the driving shaft 7 and a plurality of spring telescopic rods 81 to rotate. When the spring telescopic rods 81 rotate, they can drive the roller pressing plates 82 to rotate synchronously, so that the food additives between the roller pressing plates 82 and the feeding frame 3 can be extruded, and the lumps in the food additives can be broken to facilitate drying. At the same time, as the food additives continue to move, when the reciprocating lead screw 85 rotates with the driving shaft 7, since the sliding plate 84 is slidably connected to the fixed frame 83 and screwed to the reciprocating lead screw 85, it can drive the sliding plate 84 to slide back and forth along the fixed frame 83, so that the food additives on the inner bottom surface of the feeding frame 3 can be evenly distributed through the tooth comb openings 86, so that the food additives are more evenly distributed when they fall on the discharging rack 2.

[0079] As Figure 3 、 Figure 7 shown in the figure, the material shifting assembly includes: a transmission shaft 101, which penetrates through the top surface of the top plate 9, and the transmission shaft 101 is rotationally connected to the penetration part; a plurality of fixed sleeves 102, which are fixedly installed on the outer wall of the transmission shaft 101 below the top plate 9 in an annular array; a plurality of sliding rods 103, which are respectively slidably installed in the inner side walls of the plurality of fixed sleeves 102; a plurality of shifting plates 104, which are respectively fixedly installed at one ends of the plurality of sliding rods 103 outside the fixed sleeves 102; a plurality of arc-shaped grooves one 105, which are arranged in an annular array on the bottom surface of the top plate 9; a plurality of arc-shaped grooves two 106, which are respectively opened between adjacent ends of the plurality of arc-shaped grooves one 105; a plurality of transmission rods 107, which are respectively fixedly installed on the outer walls of the plurality of sliding rods 103, and the top ends of the transmission rods 107 are slidably connected to the arc-shaped grooves one 105 and the arc-shaped grooves two 106; a transmission mechanism, which is arranged on the top surface of the top plate 9;

[0080] When the food additives are lifted under the action of the vibration of the discharging rack 2 and pass under the top plate 9, when the second driving motor 87 is turned on, it can drive the transmission shaft 101 to rotate under the action of the transmission mechanism. When the transmission shaft 101 rotates, it drives the fixed sleeve 102, the sliding rod 103, and the dial 104 to rotate. The sliding rod 103 is slidably connected to the first arc groove 105 and the second arc groove 106 through the transmission rod 107. Therefore, when the transmission rod 107 rotates and slides along the first arc groove 105 and the second arc groove 106, it can drive the sliding rod 103 to reciprocate along the fixed sleeve 102, so that the position of the dial 104 is changed. Combined with the rotation of the dial 104 along with the transmission shaft 101, the lifted food additives can be scattered over a large area for rapid drying.

[0081] As Figure 3 shown, the transmission mechanism includes: a driven bevel gear 108 fixedly installed at the top end of the transmission shaft 101; a rotating rod 109 penetrating through the side surface of the baffle 5, and the rotating rod 109 is rotatably connected to the penetrating part. A plurality of rotating rods 109 are connected by a driven wheel and a synchronous belt. The driving shaft 7, the reciprocating lead screw 85 and one of the rotating rods 109 at the end among the plurality of rotating rods 109 are connected by a driven wheel and a synchronous belt; a driving bevel gear 1010 fixedly installed at one end of the rotating rod 109 inside the baffle 5, and the driving bevel gear 1010 meshes with the driven bevel gear 108;

[0082] When the second driving motor 87 is turned on, it can drive the rotating rod 109 to rotate through the driven wheel and the synchronous belt. The driving bevel gear 1010 at the end of the rotating rod 109 meshes with the driven bevel gear 108 at the top end of the transmission shaft 101. Therefore, it can drive the transmission shaft 101 to rotate synchronously.

[0083] As Figure 3 、 Figure 8 、 Figure 9As shown, the pusher assembly includes: two relief grooves 121 symmetrically formed on the side surface of the cross plate 11; two rotating shafts 122 respectively penetrating through the inner side walls of the two relief grooves 121; two reversing gears 1212 respectively arranged at the end of one rotating shaft 122 and on the side surface of the cross plate 11, the two reversing gears 1212 being meshed, and one of the two reversing gears 1212 being connected to the other rotating shaft 122 through a driven wheel and a synchronous belt; two rotating plates 123 respectively fixedly installed at the ends of the two rotating shafts 122; two connecting rods 124 respectively penetrating through the side surfaces of the two rotating plates 123; two fixed gear rings 125 respectively fixedly installed on the inner side walls of the two relief grooves 121; two transmission gears 126 respectively fixedly installed at one end of the two connecting rods 124 located inside the relief grooves 121, and the transmission gears 126 being meshed with the fixed gear rings 125; a driving motor three 1211 fixedly installed on the side surface of the cross plate 11, and the output end of the driving motor three 1211 being fixedly connected to one of the two rotating shafts 122; two follower mechanisms respectively arranged at one end of the two connecting rods 124 located outside the relief grooves 121.

[0084] After the food additive is deflected onto the baffle 5, it can slide down along the baffle 5. At this time, the driving motor three 1211 is turned on to drive the rotating shaft 122 to rotate. When the rotating shaft 122 rotates, it can drive one reversing gear 1212 to rotate through the synchronous belt and the driven wheel. The two reversing gears 1212 are meshed, so the two rotating shafts 122 can rotate in opposite directions, and the two rotating plates 123 can rotate synchronously. During the rotation of the rotating plate 123, the connecting rod 124 can be driven to revolve. Under the action of the meshing of the fixed gear ring 125 and the transmission gear 126, the connecting rod 124 can rotate around its own axis while revolving with the rotating plate 123, so as to always keep the follower mechanism in a vertically downward state, so as to deflect the food additive at the edge of the discharging rack 2 towards the middle position.

[0085] As Figure 8 As shown, the follower mechanism includes: a connecting seat 127 fixedly installed at the end of the connecting rod 124; a connecting frame 128 fixedly installed on the bottom surface of the connecting seat 127; a pusher plate 129 slidably installed on the inner side wall of the connecting frame 128; a plurality of springs 1210 linearly and arrayedly distributed and fixedly installed between the top surface of the pusher plate 129 and the inner top surface of the connecting frame 128.

[0086] During the rotation of the follower mechanism along with the rotating plate 123, the pusher plate 129 can contact the top surface of the discharge rack 2. And as the rotating plate 123 rotates, when the connecting seat 127 is closer to the discharge rack 2, the pusher plate 129 can enter into the connecting frame 128 so as to keep the bottom surface of the pusher plate 129 in contact with the top surface of the discharge rack 2, thereby enabling the pushing of the food additive at the edge position of the discharge rack 2. When the pusher plate 129 is separated from the discharge rack 2, under the supporting action of the spring 1210, the pusher plate 129 can be reset.
