Description

Technical Field

[0001] This utility model relates to the field of food processing and production equipment technology, and more specifically, to a spray-type cooling and drying machine. Background Technology

[0002] The cooling air dryer is an important piece of equipment used in corn cob quick-freezing and fresh-locking processing lines. It operates downstream of the corn cob cooking machine to rapidly cool and dry the cooked corn. After using the existing cooling air dryer, the customer raised several concerns. First, the discharge port of the corn cob cooking machine is too low, while the subsequent equipment of the cooling air dryer is much higher. Conventional cooling air dryers can only transport corn laterally, requiring a lifting device at the corn cob cooking machine outlet to elevate the corn cobs to the cooling air dryer, thus increasing equipment procurement costs. Second, the cooked corn from the corn cob cooking machine is at high temperature and humidity, making conventional cooling air dryers inefficient. To achieve better cooling and drying results, the cooling air drying stroke needs to be extended (multiple cooling air dryers need to be connected in series on a single processing line). Based on these customer feedback, the company needs to develop a new type of cooling air dryer to meet market demand, hence this project. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a spray-type cooling and drying machine. This invention uses an inclined installation of the main conveyor belt to achieve the lifting function. This invention uses a combination of spraying and air drying to process corn ears. First, spraying is used to quickly cool the corn ears, and then air drying is used to remove the moisture from the corn ears. This invention not only meets the needs of lifting and conveying materials, but also achieves the purpose of rapid cooling and air drying, thereby meeting the needs of customers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A spray-type cooling and drying machine includes a machine frame and a main conveyor belt. The main conveyor belt is installed at an inclination on the machine frame to form a material transport path from bottom to top. The machine frame has a feed inlet at the beginning of the drive direction of the main conveyor belt, and a material distribution device is installed at the feed inlet. The machine frame has a discharge outlet at the end of the drive direction of the main conveyor belt. A spray chamber and several sets of fans are installed sequentially on the machine frame along the drive direction of the main conveyor belt. A water tank is installed below the main conveyor belt.

[0006] Furthermore, the main conveyor belt is a stainless steel mesh conveyor belt, and several partitions are evenly distributed on the surface of the main conveyor belt. The partitions are installed vertically, and the surface of the main conveyor belt is divided into several evenly distributed conveying zones. The main conveyor belt drives the conveying zones to pass through the feed inlet in sequence, and the material distribution device feeds a row of materials into each conveying zone.

[0007] Furthermore, the fabric feeding device includes a feeding hopper and a fabric conveyor belt. The feeding hopper is connected and installed at the feeding port. The fabric conveyor belt is installed laterally. The transmission direction end of the fabric conveyor belt extends to the top opening of the feeding hopper. Several evenly distributed storage areas are formed on the surface of the fabric conveyor belt, and each storage area stores a row of materials.

[0008] Furthermore, the fabric conveyor belt starts intermittently, and each time the fabric conveyor belt starts, it moves the distance of one storage area. The fabric feeding device also includes a fabric trigger, which controls the start of the fabric conveyor belt in a linkage manner.

[0009] Furthermore, the fabric trigger includes a housing, a trigger rod, and a switch. A guide block and a spring are installed inside the housing. The guide block is adapted to be installed within the inner hole of the housing. The spring is mounted above the guide block. The trigger rod is vertical and installed through the housing. The middle section of the trigger rod is fixedly connected to the guide block. The switch is installed on the upward path of the trigger rod. The switch is a momentary trigger type. The switch circuit is connected to the fabric conveyor belt. A collision wheel is rotatably connected to the bottom end of the trigger rod. The initial position of the collision wheel is lower than the highest point of the partition of the main conveyor belt.

[0010] Furthermore, an installation gap is formed between the fabric trigger and the feed inlet, such that when the conveyor belt area of ​​one of the main conveyor belts is located directly below the feed inlet, the partition of the adjacent conveyor belt area will collide with the fabric trigger.

[0011] Furthermore, a drive roller is rotatably installed on the end face of the partition facing the discharge port. The material leans against the drive roller. The roller body is made of rubber material. One side of the drive roller shaft extends outward and is connected to a transmission gear. A rack is fixedly installed inside the machine frame. The rack is set to correspond to the movement path of the transmission gear. During the transmission of the main conveyor belt, the transmission gear meshes with the rack. The rack is installed corresponding to the positions of the spray chamber and the fan unit.

[0012] Furthermore, the spray chamber is mounted across the top of the machine frame, and a spray pipe network is laid on the top inside the spray chamber. Several sets of fans form a drying zone, and several sets of fans are evenly distributed along the length of the drying zone.

[0013] Furthermore, the water tank is installed at an angle, the angle of which is consistent with that of the main conveyor belt, and a drain pipe is installed at the lowest point of the water tank.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses an inclined installation of the main conveyor belt to achieve the lifting function. This utility model adopts a combination of spraying and air drying to process corn cobs. First, spraying is used to quickly cool the corn cobs, and then air drying is used to remove the moisture from the corn cobs. This utility model not only meets the needs of lifting and conveying materials, but also achieves the purpose of rapid cooling and air drying, thereby meeting the needs of customers.

[0016] 2. The main conveyor belt of this utility model adopts a special design. By installing partitions, the corn ears are prevented from rolling off during the lifting process. The partitions are also designed with a drive roller structure. The drive roller rotates as the main conveyor belt moves forward, thereby driving the corn ears to rotate. The rotation of the corn ears is conducive to the overall cooling by mist and the overall drying by air, which significantly improves the cooling and drying effect.

[0017] 3. This utility model is designed and installed with a feeding device at the feed inlet. The feeding device can realize the orderly feeding of corn ears, and the orderly feeding and conveying can also help improve the cooling and drying effect. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 The spray-type cooling and drying machine shown includes a frame 1 and a main conveyor belt 2. The main conveyor belt 2 is installed at an incline on the frame 1 to form a bottom-up material transport path. This invention achieves the purpose of lifting materials by the incline installation of the main conveyor belt 2. The main conveyor belt 2 of this invention adopts a stainless steel mesh conveyor belt commonly used in the food industry. In order to meet the needs of lifting materials, several partitions 21 are evenly distributed and connected on the surface of the main conveyor belt 2. The partitions 21 are installed vertically, and the partitions 21 shape the surface of the main conveyor belt 2. The conveyor belt is divided into several evenly distributed conveyor belt zones 22. Partitions 21 prevent material from rolling off (in this invention, the material refers to corn ears). The machine frame 1 has a feed inlet 11 at the starting end of the main conveyor belt 2's transmission direction. A material distribution device 6 is installed at the feed inlet 11. The conveyor belt zones 22 are sequentially passed through the feed inlet 11 by the main conveyor belt 2. To ensure cooling and drying effects, a single row of corn ears is optimal. This invention designs the material distribution device 6 to control the input of a single row of material (corn ears) to each conveyor belt zone 22. 1. A discharge port 12 is provided at the end of the main conveyor belt 2 in the transmission direction. On the machine frame 1, a spray chamber 3 and several sets of fans 41 are installed in sequence along the transmission direction of the main conveyor belt 2. The corn ears are lifted and driven by the main conveyor belt 2. During the transmission process, they are first cooled by water mist spraying, and then dried by the air blowing of the fans 41, thus completing the cooling and drying operation. During the cooling and drying operation, a large amount of water will fall from the main conveyor belt 2 (the belt surface is mesh, which allows water to pass through). Therefore, this utility model has a water tank 5 installed below the main conveyor belt 2 to collect the water. The water generated during the operation is collected in a tilted water tank 5, with the tilt angle of the water tank 5 consistent with that of the main conveyor belt 2. The collected water flows down and concentrates at the lowest point of the water tank 5. A drain pipe 51 is installed at the lowest point of the water tank 5, and a valve is installed on the drain pipe 51 to discharge the concentrated water as needed. In this utility model, the corn cob material can be lifted forward and can also complete the spray cooling and air drying operations in sequence. The design of this utility model is finalized to meet the actual use needs of customers and help to improve and maintain the company's market share in the field of cooling and drying equipment.

[0026] During the corn cob material conveying process, the number of corn cobs in each conveyor belt zone 22 should not be too large, as too many will cause stacking and affect the cooling and drying quality. The optimal solution is that the corn cobs fed into each conveyor belt zone 22 are in one row (also called one husk). One row of corn cobs is adapted to the width of the main conveyor belt 2. In order to meet the above feeding requirements, this utility model has specially designed a material distribution device 6, such as... Figure 4 As shown, the feeding device 6 includes a feeding hopper 61 and a feeding conveyor belt 62. The feeding hopper 61 is vertically connected and installed at the feeding inlet 11, and serves to receive corn cob material. The feeding conveyor belt 62 is installed horizontally, and its transmission direction end extends to the top opening of the feeding hopper 61. The feeding conveyor belt 62 carries the corn cob material to be fed. Vertical plates are also installed on the surface of the feeding conveyor belt 62 to form several evenly distributed storage areas 621. Each storage area 621 is pre-stored with a row of corn cob material. The starting end of the feeding conveyor belt 62 is located at the outlet of the preceding cooking machine, directly receiving the corn cobs output from the cooking machine outlet. Manual assistance can be provided for material distribution, ensuring that each storage area 621 only stores one row of corn cob material. The feeding conveyor belt 62 starts intermittently, and each time the feeding conveyor belt 62 starts, it moves the stroke of one storage area 621, ensuring that only one storage area 621 of corn cob material falls and feeds. The feeding device 6 also includes a feeding trigger 63, which controls the start of the feeding conveyor belt 62 in a linkage manner.

[0027] like Figure 5As shown, the fabric trigger 63 includes a housing 631, a trigger rod 634, and a switch 635. A guide block 632 and a spring 633 are installed inside the housing 631. The guide block 632 is fitted into the inner hole of the housing 631, and the spring 633 is mounted above the guide block 632. The trigger rod 634 is vertical and penetrates the housing 631. The guide block 632 is fixedly connected to the middle section of the trigger rod 634, guiding the movement of the trigger rod 634 and enabling it to move vertically up and down. Due to the presence of the spring 633, the trigger rod 634 is in an elastic installation state. The switch 635 is installed in the upward path of the trigger rod 634 and is a momentary trigger. The switch 635 is connected to the fabric conveyor belt 62. Each time the switch 635 is pressed, it controls the fabric conveyor belt 62 to move one stroke. A rotatable impact wheel 636 is rotatably connected to the bottom of the trigger rod 634. The initial position of the impact wheel 636 is lower than the partition 21 of the main conveyor belt 2. At the highest point, during the transmission of the main conveyor belt 2, the partition 21 will collide with the impact wheel 636. Since the trigger rod 634 is elastically connected, it will create the effect of the trigger rod 634 pushing upward and the spring 633 compressing. The pushing trigger rod 634 will press the trigger switch 635, thereby controlling the fabric conveyor belt 62 to move one stroke. As the partition 21 moves and squeezes through, under the restoring force of the spring 633, the trigger rod 634 returns to the starting position, waiting for the impact of the next partition 21. In order to form a smooth feeding effect, this utility model forms an installation gap between the fabric trigger 63 and the feed port 11 (installed with a distance). When the conveying area 22 of the main conveyor belt 2 is located directly below the feed port 11, the partition 21 of the adjacent conveying area 22 will collide with the fabric trigger 63, forming the fabric conveyor belt 62 to move one stroke, releasing a row of corn cob material through the feed port 11 into the corresponding conveying area 22 (the feeding principle of front pushing and rear putting).

[0028] During the corn cob material conveying process, the spraying and blowing directions are fixed. If the corn cobs do not move, the position exposed to mist and wind remains the same, which is not conducive to improving cooling and drying effects. Therefore, this utility model has made an improved design, such as... Figure 2 and Figure 3As shown, a drive roller 23 is rotatably mounted on the end face of the partition 21 facing the discharge port 12. The length of the drive roller 23 is adapted to the width of the main conveyor belt 2. During the process of the corn cob material being lifted from low to high, the corn cob material leans against the drive roller 23. The roller body of the drive roller 23 is made of rubber material, which increases friction without damaging the surface of the corn cob. One side of the drive roller 23 has a shaft end that extends outward and is connected to a transmission gear 231. A rack 24 is fixedly installed inside the machine frame 1. The rack 24 is set to correspond to the movement path of the transmission gear 231. During the transmission of the main conveyor belt 2, the transmission gear 231 meshes with the rack 24, thereby driving the rotation of the drive roller 23. The rotation of the corn cob material is achieved when the rotation is complete. The rack 24 is installed at the positions corresponding to the spray chamber 3 and the fan 41. In other words, the rotation of the corn cob material occurs during the spraying and drying operations, so that the surface of the corn cob can be evenly sprayed and air-dried. This design does not affect the conveying of the corn cob and can significantly improve the cooling and drying effect of the corn cob. After applying this utility model, the number of conventional cooling and drying machines connected in series can be significantly reduced. Previously, the production line required 3-4 conventional cooling and drying machines connected in series to achieve the cooling and drying effect. Now, only one of this utility model and one conventional cooling and drying machine connected in series can achieve the original effect, which can reduce the equipment procurement cost.

[0029] like Figure 1 As shown, the spray chamber 3 is mounted on the top of the machine frame 1. The top of the inner side of the spray chamber 3 is covered with a spray pipe network 31. The spray must use edible room temperature water. The spray pipe network 31 is connected to a water pump. Several sets of fans 41 form a drying zone 4. Several sets of fans 41 are evenly distributed along the length of the drying zone 4. Each set of fans 41 covers the width of the main conveyor belt 2.

[0030] This invention is applied to the corn cob quick-freezing and freshness-locking processing production line in our company, but it is not limited to corn cob processing and can also be used in other food processing.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
