Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to an intelligent drying line. Background Art

[0002] Fresh star anise is green, and the finished product after drying is deep reddish brown. There is a process called "killing the green" before drying star anise. In the long run, it is killed by boiling in boiling water or smoking over charcoal fire before entering the drying process. Since star anise takes a long time to dry naturally, in order to prevent it from getting moldy, it is generally necessary to fumigate repeatedly with sulfur, which has a great impact on the quality of star anise and does not meet food safety requirements.

[0003] In the existing drying process, the equipment simply dries and cannot achieve active humidification. During the drying process of star anise, our equipment uses a method of simulating sunlight and night dew, so that the star anise drying line can maintain drying during the operation of the equipment, and can actively increase the humidity and oxygen content, thereby ensuring that the star anise turns red.

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0015] Example 1

[0016] The intelligent drying line includes a dryer 1, wherein the feeding port of the dryer 1 is connected to the feeding port of the blanching machine 2 through a conveyor belt, the feeding port of the dryer 1 is provided with a collecting box 3, the dryer 1 is connected with a steam generator 4, and the steam generator 4 is respectively connected with the dryer 1 and the blanching machine 2 through a gas cylinder 5; a plurality of layered material carts 6 with equal intervals are longitudinally arranged inside the dryer 1, a first roller 7 is arranged at one end of the layered material cart 6 close to the feeding port of the dryer 1, a chute 8 matching the first roller 7 is formed inwardly on one side of the dryer 1, and the size of the chute 8 is consistent with that of the layered material cart 6, and the layered material The other end of the car 6 is extended out on both sides and connected with a second roller 9, and a slide 10 is arranged at the bottom of the second roller 9, and the slide 10 is installed on the side wall on the other side of the dryer 1, and all ends of the slides 10 are connected by a partition 11, and a hole 12 of the same size as the layered material car 6 is opened on the partition 11, and a conveyor belt 13 is arranged on the surface of the topmost layered material car 6, and the first roller 7 and the second roller 9 are driven by a motor 14, and a temperature and humidity recorder 15 is installed inside the dryer 1, and a dehumidification fan 16 is installed on the top of the dryer 1, and a radiator 17 is arranged inside the dryer 1;

[0017] When the first roller 7 moves to the end of the chute 8 away from the feeding port of the dryer 1, the second roller 9 abuts against the side wall of the other side of the dryer 1 and one end of the layered material cart 6 abuts against the partition 11; when the first roller 7 moves to the other end of the chute 8, the second roller 9 abuts against the partition 11 and the layered material cart 6 completely enters the chute 8; by presetting the movement of each layered material cart 6 and coordinating the conveyor belt on the top layered material cart 6, it can be ensured that each layer of the layered material cart 6 can be evenly covered with materials, and all layers are in the initial state. The material carts 6 are all located in the chute 8. When the product line starts to start, the timing starts. After the preset time is reached, the material cart 6 of the bottom layer slides out of the chute 8, and the material cart 6 of the top layer starts to slide. At this time, the material just enters the conveyor belt from the feeding port. The material falls into the layer material cart 6 after being driven by the conveyor belt. With the sliding of the top layer material cart 6, the material falls evenly onto the lower layer material cart 6. After the set time, the upper layer material cart 6 starts to slide out, and the previous steps are repeated.

[0018] After the baking is completed, the layered material cart 6 retracts, and the material falls into the bottom layer of the dryer 1. The bottom of the dryer 1 has a certain slope, and the lowest end of the slope is connected to the collection box 3 to complete the drying.

[0019] The radiator 17, the temperature and humidity recorder 15, the motor 14, and the steam generator 4 are all connected to a control box 18, in which a control chip is integrated, and a liquid crystal touch display is installed on the surface of the control box 18. The temperature and humidity are fully automatically controlled to ensure that the drying environment box can meet the use of different process requirements at the same time.

[0020] The steam generator 4 is connected to a water tank 19 , the water tank 19 is connected to a pure water machine 20 , and the steam generator 4 is also connected to a liquid phase vaporization furnace 21 .

[0021] The process is as follows:

[0022] 1. Put the fresh star anise through the blanching machine for 3-5 minutes to make the material yellow; then adjust the star anise drying line process to high temperature and high humidity mode to meet the equipment requirements, adjust the temperature to 75℃, humidity to 90%, and dry for 8 hours. Note that there is no need to dehumidify at this stage, mainly to control the color.

[0023] 2. Adjust the drying mode of the octagonal heat pump dryer to drying + dehumidification, adjust the temperature to 60℃, and dry for 8 hours. Note that a lot of dehumidification should be carried out at this stage.

[0024] 3. Keep the drying + dehumidification mode, adjust the temperature to 50℃, and dry for 8 hours. Note that a lot of dehumidification should be done during this stage. Pay attention to the moisture content, which should be between 13-18%.

[0025] In addition, the steam generator 4 is used to supply heat to the blanching machine 2, and the temperature is controlled to be above 90 degrees. At the same time, the dryer 1 is provided with heat, humidity and oxygen. The residual heat after the heat is supplied through the heat exchanger is fed back to the blanching machine 2 to provide heat for the blanching machine 2. The control system controls the supply amount of the steam generator 4, controls the temperature and humidity in the dryer 1, and controls the temperature of the blanching machine 2 at the same time.

[0026] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
