Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a portable air source heat pump fruit and vegetable drying machine. Background Art

[0002] With the increasing demand for healthy food, the market demand for dried fruits and vegetables, as a form of food that is rich in nutrition, easy to preserve and eat, is growing. Generally, air source heat pump fruit and vegetable dryers are used to dry them. Air source heat pump fruit and vegetable drying equipment is a drying equipment that uses air as a heat source and performs efficient energy conversion through fans and heat sources. It absorbs low-temperature air in the environment and raises it to a suitable temperature for drying fruits and vegetables, while reducing energy consumption during the drying process. At present, most fruit and vegetable dryers on the market are only suitable for fruits and vegetables in a single form. They can only process sliced ​​fruits and vegetables or dry whole fruits. They cannot meet the needs of different users for drying fruits and vegetables in different forms at the same time. The functions are relatively single. This leads to the need to purchase multiple different types of drying equipment in actual production or home use. If you need to dry fruits and vegetables in various forms, you need to increase the cost and space occupancy. In addition, traditional fruit and vegetable dryers have serious deficiencies in heat source utilization. They often directly discharge heat sources into the surrounding environment without effectively recovering and recycling waste heat, which not only causes a lot of energy waste, but also increases the drying cost.

[0003] Moreover, traditional fruit and vegetable drying equipment mostly relies on manual operation for material input and output, which is not only labor-intensive but also inefficient. In large-scale production, manual operation is prone to errors, resulting in damage to the material or poor drying effect.

[0004] Based on this, a convenient air source heat pump fruit and vegetable drying equipment was designed. It adopts a double-bin structure and can dry fruits and vegetables of different sizes. It also adopts a hot air circulation system to improve energy utilization and maximize the utilization of thermal energy. It cooperates with the automatic feeding and discharging mechanism to automatically deliver the material, thereby improving production efficiency, reducing labor intensity, and also improving the stability of product quality. Summary of the invention

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0038] As attached Figure 1 , Figure 2 , Fig.12 and Fig.13As shown, a portable air source heat pump fruit and vegetable drying machine comprises a box body 1, an isolation plate and an air guide mechanism 4. The box body 1 is a rectangular hollow structure with one end open, and the middle of the box body 1 is divided into a chamber A and a chamber B by an isolation plate. The first carrier bracket 10 and the second carrier bracket 15 are respectively arranged in the chamber A and the chamber B. The upper part of the box body 1 is provided with an air guide mechanism 4 for drying fruits and vegetables; the air guide mechanism 4 comprises a first air guide bin 401, an air source heat pump 405, a first air guide duct 404, and a first guide pump 40 2. The second air duct 403 and the dehumidification mechanism 9. The air source heat pump 405 is connected to the chamber A through the first air duct 404, and a plurality of jet ducts 406 are arranged inside the chamber A. The first air guide bin 401 is arranged on the top of the chamber A, and the first air guide bin 401 is connected to the dehumidification mechanism 9 through the first air guide pump 402 and the second air duct 403 to remove moisture from the chamber A. The dehumidification mechanism 9 is arranged on the top of the box body 1 to dehumidify the discharged hot air and then send it into the chamber B.

[0039] It should be noted that fresh fruits and vegetables contain a lot of water, which provides good conditions for the growth of microorganisms and the activity of enzymes. After most of the water is removed by drying, the growth and reproduction of microorganisms and the activity of enzymes will be greatly inhibited. Therefore, the shelf life of dried fruits and vegetables will be greatly extended. Moreover, these dried fruit and vegetable snacks do not need to worry about spoilage like fresh fruits and vegetables. They can be stored for a long time at room temperature, which is convenient for people to enjoy during travel, outdoor sports and other scenarios. Traditional fruit and vegetable drying equipment generally generates hot air through air source heat pumps, and then guides the hot air into the drying equipment to achieve the drying of fruits and vegetables. However, this equipment has the following disadvantages. First, the air is guided from the bottom to the top. After contacting the fruits and vegetables on the drying rack, it will produce a lot of moisture. The moisture needs to pass through multiple drying layers to be discharged upward, and the fruits and vegetables are dried during the moisture guidance process. This also causes the fruits and vegetables at the bottom to dry faster, while the fruits and vegetables in the top drying layer are dried slower, and the heating is uneven. Secondly, the hot air flow discharged during the drying process is generally discharged directly to the outside because it carries moisture, resulting in energy waste and ineffective utilization. Finally, in the drying preparation process, the loading and unloading of materials requires manual operation by the operator, and the entire drying equipment is relatively high, and it is not easy to send the fruits and vegetables on the drying net into the drying box. Based on the above three defects, the drying equipment is improved so that it can be heated evenly, and the discharged hot air flow can be recycled. An automatic loading system is added to realize automatic loading and unloading, thereby improving the convenience and practicality of the equipment.

[0040] It should be further explained that, in order to achieve the purpose of uniform heating, chamber A and chamber B are constructed inside the box 1, both of which can introduce hot air flow to carry out drying operations. An air source heat pump 405 is provided on one side of the box 1, which transmits the generated hot air flow to chamber A with the help of the first air guide duct 404, and then the hot air flow is ejected from the jet ducts 406 on both sides of chamber A to perform drying operations on the fruits and vegetables placed on the first carrier 10. This unique way of air intake from the side cooperates with the first carrier 10 to effectively achieve uniform heating of fruits and vegetables. In summary, compared with traditional heating methods, the fruits and vegetables placed on each first carrier 10 can be heated independently, successfully avoiding the uneven heating caused by the transmission of hot air from bottom to top, greatly improving the quality and efficiency of the drying operation, and ensuring that the drying effect of fruits and vegetables is more ideal and stable.

[0041] It should be further explained that an exhaust port is provided at the top of chamber A, and the hot air flow after drying enters the first air guide chamber 401 through the exhaust port along with moisture, and is then sent to the dehumidification mechanism 9 for dehumidification treatment through the first guide pump 402 to remove the internal moisture, so that the hot air returns to a dry state, and then the hot air is introduced into chamber B, thereby realizing the recycling of hot air flow in the entire system, greatly improving energy utilization and reducing energy consumption.

[0042] like Figure 1-Figure 3 As shown, the dehumidification mechanism 9 includes a second air guide bin 901, a rotating bracket 902, a fixing ring 903, a dehumidification assembly 910, a third air guide bin 907, a third air guide duct 908 and a first heater 909. The second air guide bin 901 is arranged on the top of the box body 1, and the third air guide bin 907 is arranged inside the second air guide bin 901. The third air guide bin 907 is connected to the first heater 909 on the first sealing plate 13 through the third air guide duct 908; the rotating bracket 902 is arranged on the rotating shaft of the bearing seat of the box body 1, and fixing rings 903 are arranged at both ends of the rotating bracket 902. 3. A dehumidification component 910 is arranged inside the fixed ring 903; a first synchronous wheel is arranged on the rotating shaft, and the first synchronous wheel is connected to the second synchronous wheel on the output shaft of the first drive motor 906 through the first synchronous belt 904; the first drive motor 906 is arranged on the box body 1 through the motor support 905, and is used to drive the rotation of the rotating bracket 902; the third air guide chamber 907 is a rectangular hollow cavity structure with an upper opening, and a circular air inlet is arranged on the third air guide chamber 907, and the air inlet is arranged corresponding to the fixed ring 903 of the rotating bracket 902, so as to introduce the dehumidified hot air into the chamber B.

[0043] It should be noted that in order to dehumidify the airflow discharged from chamber A, a dehumidification mechanism 9 is designed, wherein a rotating bracket 902 is arranged on the rotating shaft of the bearing seat, and a fixing ring 903 and a dehumidification component 910 are respectively arranged on both sides of the rotating bracket 902, and the moisture in the hot airflow is removed by the dehumidification component 910. In this process, a second air guide bin 901 is firstly arranged on the top of the box body 1 for introducing the airflow, and the rotating bracket 902 can rotate to transfer the fixing ring 903 into the chamber of the second air guide bin 901, and the air inlet is matched with the dehumidification component 910 on the fixing ring 903, and the moisture is adsorbed by the dehumidification component 910, and the remaining dry hot airflow will enter the third air guide bin 907, and be introduced into the chamber B through the third air guide duct 908, so as to dry the fruits and vegetables on the second carrier bracket 15.

[0044] It should be further explained that in order to achieve the recycling of the dehumidification component 910, the rotating bracket 902 can be rotated under the drive of the first drive motor 906, and the dehumidification components 910 at both ends are used alternately, thereby achieving the purpose of cyclic dehumidification; in order to increase the temperature of the introduced air flow, a first heater 909 is set on the third air duct 908, which is started as needed to heat the hot air flow again, thereby increasing the air temperature inside chamber B.

[0045] It should be noted that the dehumidification component 910 can choose to use dry silica gel. Silica gel has a rich microporous structure, and the silanol groups on its surface can form hydrogen bonds with water molecules to achieve the adsorption of moisture. When the silica gel is saturated with adsorption, it can be heated to 120°C to break the hydrogen bonds, allowing the adsorbed moisture to be desorbed and restored to a dry state, and the silica gel can restore its adsorption capacity.

[0046] like Figure 1 , Figure 2 , Figure 3 and Fig.13 As shown, a drying mechanism 8 is also included, and the drying mechanism 8 includes a fourth air guide bin 801, a second heater 802, a fourth air guide duct 804 and a second air guide pump 805. The fourth air guide bin 801 is arranged on the box body 1, and a second heater 802 is arranged inside the fourth air guide bin 801, and an air outlet 803 of the second heater 802 is arranged corresponding to the other fixed ring of the rotating bracket 902; one side of the fourth air guide bin 801 is connected to the second air guide pump 805 on the side of the box body 1 through the fourth air guide duct 804, so that the hot air inside the chamber B is discharged for drying the dehumidification component 910.

[0047] It should be noted that in order to achieve the purpose of recycling the dehumidification component 910, a drying mechanism 8 is specially designed, which can perform drying operations on the dehumidification component 910 placed on the rotating bracket 902, and effectively remove the moisture adsorbed by the dehumidification component 910 to achieve its reuse. Specifically, the fourth air guide bin 801 is connected to the second guide pump 805 on the side of the box body 1 by means of the fourth air guide duct 804, so as to lead the hot air flow in the chamber B. When the hot air flow flows through the second heater 802 inside the fourth air guide bin 801, its temperature is further increased. Subsequently, the high-temperature air flow acts on the upper dehumidification component 910, and through the drying operation, the moisture inside the dehumidification component 910 is completely removed, so that its adsorption capacity is restored.

[0048] like Figure 1 , Figure 7 , Figure 8 , Fig. 9 and Fig.12 As shown, it also includes a driving mechanism 2, which includes a side fixed plate 201, a first rectangular opening 202, a lifting support 204, a first slide 203, a second drive motor 205 and an electric push cylinder 208, a third drive motor 207 and a first gear 209. The lifting support 204 is movably connected to the first slide 203 on the side fixed plate 201 through a first slide groove on the side, and a support frame 212 is provided on the lifting support 204, and an electric push cylinder 208 is provided on the support frame 212. The output shaft of the electric push cylinder 208 is connected to the lifting platform 215; the lifting platform 215 is connected to the second inner part of the support frame 212 through the second slide grooves on both sides. The slide bar 206 is slidably connected, and a second drive motor 205 is arranged at one end of the lifting platform 215. The output shaft of the second drive motor 205 is connected to the first rotating shaft 213 inside the box body 1 through the transmission structure 6; a third drive motor 207 is arranged on the lifting support 204, and the first gear 209 on the output shaft of the third drive motor 207 is meshed and connected with the first rack 210 on the side fixed plate 201, and the lifting and lowering of the lifting support 204 is realized under the drive of the third drive motor 207; a first rectangular opening 202 is arranged on the side fixed plate 201, and the transmission structure 6 passes through the first rectangular opening 202 and is connected to the first rotating shaft 213.

[0049] It should be further explained that, in order to achieve the function of automatic loading and unloading, a first rotating shaft 213 is provided in both chamber A and chamber B, and a first sprocket, a second sprocket and a transmission chain 214 are arranged on the first rotating shaft 213 to construct a transmission mechanism, thereby automatically exporting the first carrier 10 and the second carrier 15 during the transmission process of the transmission chain 214. In view of the fact that each set of transmission mechanisms needs to cooperate with the feeding mechanism 3, each transmission mechanism is required to have the ability of independent transmission. The traditional design idea is usually to equip each first rotating shaft 213 with a separate motor to achieve drive. However, this method will result in a large number of motors required, which greatly increases the manufacturing cost of the entire equipment. In view of this, a driving mechanism 2 is specially designed. Specifically, one side of the lifting support 204 is connected to the first slide groove and the first slide bar 20 on the side fixed plate 201 through the first slide groove. 3 is movably connected, a third driving motor 207 is arranged on the lifting support 204, and a first gear 209 on the output shaft of the third driving motor 207 is meshed and connected with a first rack 210 on the side fixing plate 201. The lifting support 204 is lifted and lowered under the drive of the third driving motor 207, and then the second driving motor 205 inside the lifting support 204 can also be lifted and lowered. Moreover, the second driving motor 205 can move forward and backward under the drive of the electric pushing cylinder 208 with the help of the lifting platform 215 and the electric pushing cylinder 208, and can be connected with the first rotating shaft 213 through cooperation with the transmission structure 6. In this way, the second driving motor 205 can be accurately moved to the required transmission position according to actual needs, and then the first rotating shaft 213 can be driven to operate, which effectively solves the problem of increased cost caused by too many motors in the traditional method, and improves the cost performance and operation efficiency of the equipment.

[0050] like Figure 1 , Figure 7 , Fig.10 , Fig.11 and Fig.12As shown, a first sprocket and a second sprocket are arranged on the upper part of the first rotating shaft 213, and the first sprocket and the second sprocket are connected by a transmission chain 214 to form a transmission mechanism, and the transmission chain 214 is located in the chain groove of the box body 1, and a first carrier bracket 10 is arranged on the transmission chain 214; the transmission structure 6 includes a first connecting rod 601, a second connecting rod 604, a locking rod 603 and a buckle hole 607, and the first connecting rod 601 and the second connecting rod 604 are respectively arranged on the first rotating shaft 213 and the second driving shaft.
