Description

Technical Field

[0001] The utility model relates to the technical field of nut processing, in particular to a drying device for nuts. Background Art

[0002] Nuts are a type of closed fruit with a hard peel and one or more seeds (such as chestnuts, almonds, etc.). Nuts can be divided into herbaceous seed nuts and woody nuts. Nuts are the essence of plants and are generally rich in nutrients, containing high levels of protein, oil, minerals, and vitamins. They have excellent effects on human growth and development, physical fitness, and disease prevention.

[0003] Nut processing refers to the process of removing the shell of the fruit by manual or mechanical methods to make kernels. The process of processing nuts into kernels can generally be divided into: raw material processing (picking, washing, drying, grading, etc.), shelling, drying, peeling, grading, packaging and other processes. Among them, baking and drying is an important step in nut processing and production. The effect of drying will affect the production efficiency of subsequent processing and the taste of the final product. Dried nuts can prevent nuts from getting moldy and extend the shelf life of nuts. However, most of the existing methods for drying nuts are to dry them in a drying box, spread the nuts on a drying plate, and then push them into the drying box for drying. However, this method is not suitable for nuts with different sizes at both ends, and uneven drying is prone to occur. For example, cashew nuts, due to the different sizes of the two ends of cashew nuts, simply laying them out for drying will result in one end being over-dried, resulting in a rough taste and loss of nutrients, or one end being dried to an ideal dryness, which is prone to mold. In addition, the method of drying nuts by spreading them on a drying plate requires the nuts to be turned over for drying, which is troublesome to operate as a whole, has low drying efficiency, and is prone to over-drying. Utility Model Content

[0004] The utility model aims to provide a drying device for nuts which has the advantages of uniform drying, simple operation and high drying efficiency, so as to solve the technical problems of poor nut drying effect, low drying efficiency and time-consuming and labor-intensive in the prior art.

[0005] In order to solve the above technical problems, the solution adopted by the utility model is as follows:

[0006] A drying device for nuts, comprising a dryer, a placement trough, a dust remover, a conveying device, a controller, a detection device and a base; the conveying device is installed on the base, connected to the dust remover on the left side and to the dryer on the right side; the top of the dust remover is connected to the placement trough, and impurities in the nuts are removed by the dryer; the controller is fixedly installed on the outside of the dryer, and the controller is a single-chip microcomputer; the detection device is fixedly installed in the dryer and connected to the controller; the dryer comprises a stirring device and a heating device; the stirring device is located inside the dryer; the heating device comprises a drying lamp and a hot air blower; the drying lamps are evenly distributed around the inner side of the dryer; the hot air blower is fixedly installed below the dryer; an outlet is provided on the side of the dryer away from the conveying device, and a sealing door matching the outlet is provided.

[0007] Furthermore, the stirring device comprises a rotating rod, stirring blades and a motor; the rotating rod is located inside the dryer, the lower end is connected to the inner wall of the dryer, and the upper end extends out of the dryer and is connected to the motor; the stirring blades are provided with more than four, evenly distributed on the rotating rod (1011), and are mesh-shaped. After the nuts enter the dryer through the conveying device, the motor is turned on, the motor drives the rotating rod to rotate, and then drives the stirring blades to rotate, stirring and turning the nuts. The mesh-shaped stirring blades facilitate the hot air to flow evenly in the dryer, thereby accelerating the drying efficiency.

[0008] Furthermore, the impurity remover includes a fan and a slag outlet; one side of the lower portion of the placement slot is the fan, and the other side is the slag outlet. The fan of the impurity remover removes impurities such as leaves mixed in the nuts and blows the impurities out of the slag outlet to prevent the leaves from being dried and broken in the dryer, and from accumulating in the dryer and being difficult to clean.

[0009] Furthermore, a feeder and a motor A are provided at the bottom of the placement slot; the feeder includes a feeder blade and a rotating wheel, and the feeder blades are provided with more than three blades, which are evenly distributed on the rotating wheel; the motor A is located outside the placement slot, and the rotating end is deeply inserted into the placement slot and connected to the rotating wheel. The motor A of the feeder drives the rotating wheel to rotate, and then drives the feeder blade to rotate, so as to feed quantitatively, which is convenient for the subsequent impurity removal machine to perform impurity removal work.

[0010] Furthermore, the detection device includes a temperature sensor and a humidity detector; three temperature sensors are provided and evenly distributed in the dryer; the humidity detector is fixedly installed inside the dryer; and the controller is connected to the temperature sensor and the humidity detector. The temperature sensor monitors the temperature inside the dryer in real time to avoid the phenomenon that the nut nutrients are lost due to excessively high temperature or the nut cannot be effectively dried due to excessively low temperature. The humidity detector can monitor the moisture content of the nut to avoid the phenomenon that the nut is over-dried.

[0011] Furthermore, an alarm device is provided at the top of the dryer; the alarm device is connected to the controller. The controller sets the moisture content of the nuts and the temperature in the dryer. When the nuts reach the drying effect, that is, when the moisture content in the nuts reaches the standard, the alarm device sounds an alarm to remind the staff to take the nuts out of the dryer, or when the temperature in the dryer is too high, the alarm device sounds an alarm to remind the staff to adjust the temperature and lower the temperature in the dryer.

[0012] Furthermore, the humidity detector is a near-infrared online moisture meter. The near-infrared online moisture meter has the characteristics of high temperature resistance, moisture resistance, vibration resistance and high-precision measurement, and can be placed in the dryer to detect the moisture of nuts.

[0013] Furthermore, the base is inclined toward the outlet, and the conveying device is a conveyor belt. The inclined base makes the dryer relatively inclined, and after drying is completed, when the stirring device stops, the nuts slide toward the outlet by gravity, and the nuts can be taken out of the dryer in combination with the sealing door.

[0014] The working principle of the utility model is as follows:

[0015] When in use, the nuts are placed in the placement slot, and the motor A of the placement slot drives the unloading fan blades to rotate and unload quantitatively. The impurities are removed by the fan of the impurity remover, and the impurities are discharged through the slag outlet. The nuts after impurities removal fall onto the conveyor device and are conveyed to the dryer by the conveyor device. The motor of the dryer drives the rotating fan blades to rotate to stir and turn the nuts. The drying lamp and the hot air blower inside the dryer heat and dry the nuts. The temperature inside the dryer is monitored in real time by the temperature sensor, and the moisture content of the nuts is monitored by the humidity detector. Combined with the alarm, the drying effect of the nuts can be effectively judged to avoid the temperature in the dryer being too high or too low. After the drying is completed, the nuts slide to the side of the outlet by gravity, the sealed door is opened, and the motor drives the rotating fan blades to rotate slowly, and all the nuts between the rotating fan blades are taken out through the sealed door.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1. The utility model can adjust the drying temperature of the dryer through a controller combined with a detection device to dry the nuts with a hot air blower and a drying lamp, and can stir and turn the nuts with a stirring device to evenly dry the nuts, thereby reducing the drying time of the nuts and improving the drying efficiency of the nuts.

[0018] 2. The impurity remover of the utility model can remove impurities contained in nuts, such as leaves, branches, etc., to prevent the impurities from being broken after drying in the dryer and accumulating in the dryer, which makes it difficult to clean.

[0019] 3. The utility model can monitor the temperature in the dryer and the moisture content of nuts in real time through the temperature sensor and the humidity detector. When the temperature of the dryer is too high, too low or reaches the nut drying standard, the controller controls the alarm device to sound an alarm, which can effectively avoid the phenomenon of excessive drying of nuts or substandard drying of nuts.
