Description

Technical Field

[0001] This utility model belongs to the field of wolfberry processing technology, and more specifically, it relates to an integrated device for wolfberry freshness locking, drying and sorting. Background Technology

[0002] Goji berries are a plant with both medicinal and food value, and have extremely high economic and medicinal value. Because fresh goji berries have a high water content, they are difficult to store and transport for a long time. Therefore, they usually need to be dried to extend their shelf life. At the same time, in order to ensure the quality and market value of goji berries, they also need to be sorted during processing to remove impurities and substandard fruits.

[0003] Application number CN201810874050.0 discloses an integrated drying and sorting device for goji berries, including a base plate, a drying chamber, a material rack, sieve boxes, a cam mechanism, fans, a return air duct, a material box, a preheating chamber, a pneumatic conveying device, side plates, and an electric heating plate. The drying chamber and the material box are respectively mounted on the base plate and connected by the return air duct. The material rack is movably mounted inside the drying chamber and is driven by the cam mechanism. Four sieve boxes are movably mounted on the material rack. Several fans are mounted on the drying chamber. The preheating chamber is installed inside the material box. One end of the pneumatic conveying device is installed inside the preheating chamber, and the other end is located above the material rack. The heat from drying is transferred to the preheating chamber through the return air duct, preheating the goji berries to be dried, thus making full use of energy. The cam mechanism drives the goji berries back and forth in the sieve boxes, thereby achieving the sieving of goji berries and accelerating moisture evaporation during the sieving process.

[0004] Based on the above patent searches and understanding of existing applications of goji berry freshness preservation, drying, and sorting: Traditional goji berry drying methods often employ high-temperature drying, which easily damages the active ingredients in goji berries, such as carotenoids and polysaccharides. It also damages the natural waxy layer on the surface of the fruit, resulting in poor color and plumpness of the dried fruit, failing to achieve a good freshness preservation effect. Furthermore, during the drying process, impurities and substandard fruits in the goji berries cannot be screened and removed in time, affecting the quality of the goji berries. In addition, the lack of effective turning of the goji berries results in uneven drying and low drying efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an integrated device for locking in freshness, drying, and sorting goji berries. This device solves the problems of existing goji berry drying methods that often use high-temperature drying, which easily damages the active ingredients such as carotenoids and polysaccharides in goji berries and also damages the natural wax layer on the surface of the fruit, thus failing to achieve a good freshness-locking effect. Furthermore, during the drying process, impurities and substandard fruits in the goji berries cannot be screened and removed in time, affecting the quality of the goji berries. Additionally, the lack of effective turning of the goji berries results in uneven drying.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An integrated device for preserving freshness, drying, and sorting goji berries includes a frame; a receiving rack is installed at the top of the frame, a strip conveyor belt is installed at the upper part of the inside of the receiving rack, a control unit is fixedly installed at the middle right side of the receiving rack, a vacuum pump is installed at the upper end of the control unit, a low-temperature vacuum drying chamber is fixedly installed at the middle top of the receiving rack, the top of the low-temperature vacuum drying chamber is connected to the vacuum pump through a pipe, and two elastically resetting chamber doors are respectively installed at the front and rear ends of the low-temperature vacuum drying chamber.

[0008] According to one embodiment of the present invention, a screening frame is placed at the top front end of the strip conveyor belt, the middle of the screening frame is designed to be through, and a support plate is provided at the top front end of the screening frame. The rear end face of the top support plate of the screening frame is fixedly connected to the front end of the control frame.

[0009] According to one embodiment of the present invention, a motor is fixedly installed at the bottom of the control frame, the motor is located at the middle of the top front end of the screening rack, and the motor shaft is fixedly connected to the lower part of the U-shaped frame.

[0010] According to one embodiment of the present invention, the U-shaped frame is located inside the control frame, and the middle protrusion of the U-shaped frame is rotatably connected to the front end of the transmission rod, which is located inside the control frame.

[0011] According to one embodiment of the present invention, the rear end position of the transmission rod is rotatably connected to the middle position of the front end of the sliding rod, and the sliding rod is slidably connected to the rear end position inside the control frame.

[0012] According to one embodiment of the present invention, a screening box is slidably connected to the rear end of the screening rack. A clamping groove is provided at the middle of the front end of the screening box, and a threaded hole is provided at the middle of the front end of the top of the screening box. A bolt is rotatably connected in the threaded hole of the screening box. The bottom of the bolt is located in the clamping groove of the screening box. The rear end of the sliding rod is inserted into the clamping groove of the screening rack, and the bottom of the bolt is attached to the top rear end of the sliding rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting up a low-temperature vacuum drying oven and a vacuum pump, goji berries can be dried under low-temperature vacuum conditions. The vacuum environment lowers the boiling point of water, allowing fresh goji berries to dehydrate rapidly at a low temperature of 30-40℃. This avoids the damage of high temperatures to active ingredients such as carotenoids and goji polysaccharides, while protecting the natural waxy layer on the surface of the fruit. This results in dried fruit with a color and plumpness similar to fresh fruit, achieving a good freshness-locking effect.

[0015] Through the cooperation of components such as motor, U-shaped frame, transmission rod and sliding rod, the screening box reciprocates inside the screening frame. The goji berries are constantly turned over in the screening box. During the turning process, impurities and unqualified fruits fall through the through part in the middle of the screening frame and pass through the gap of the strip conveyor belt to fall into the receiving rack for temporary storage. This achieves effective screening of impurities and unqualified fruits in goji berries and improves the quality of goji berries.

[0016] As the screening box moves back and forth inside the screening rack, the goji berries are constantly turned over. This turning effect in the drying process of the low-temperature vacuum drying oven ensures uniform drying of the goji berries, avoids over-drying or under-drying in certain areas, improves the efficiency of freshness-locking drying, and helps to ensure the overall quality of the goji berries.

[0017] This device integrates the functions of preserving freshness, drying, and sorting goji berries. Through reasonable structural design and coordination between components, it reduces the equipment's footprint and operating steps, improves production efficiency, and lowers production costs.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0029] Example:

[0030] As attached Figure 1 To be continued Figure 6 As shown:

[0031] This utility model provides an integrated device for locking freshness, drying and sorting goji berries, including a frame 1; a receiving rack 101 is provided at the top of the frame 1, a strip conveyor belt 102 is provided at the upper part of the inside of the receiving rack 101, a control unit 103 is fixedly installed at the middle right side of the receiving rack 101, a vacuum pump 104 is provided at the upper end of the control unit 103, a low temperature vacuum drying chamber 105 is fixedly installed at the middle top of the receiving rack 101, the top of the low temperature vacuum drying chamber 105 is connected to the vacuum pump 104 through a pipe, and two elastically resetting chamber doors are provided at the front and rear ends of the low temperature vacuum drying chamber 105.

[0032] Among them, a screening frame 2 is placed at the top front end of the strip conveyor belt 102. The middle part of the screening frame 2 is designed to be through, and a support plate is provided at the top front end of the screening frame 2. The rear end face of the top support plate of the screening frame 2 is fixedly connected to the front end of the control frame 201.

[0033] Among them, a motor 202 is fixedly installed at the bottom of the control frame 201. The motor 202 is located at the middle of the top front end of the screening rack 2, and the rotating shaft of the motor 202 is fixedly connected to the lower part of the U-shaped frame 203.

[0034] The U-shaped frame 203 is located inside the control frame 201, and the middle protrusion of the U-shaped frame 203 is rotatably connected to the front end of the transmission rod 204, which is located inside the control frame 201.

[0035] The rear end of the transmission rod 204 is rotatably connected to the middle of the front end of the sliding rod 205, and the sliding rod 205 is slidably connected to the rear end of the control frame 201.

[0036] The screening rack 2 has a screening box 206 slidably connected to its rear end. The screening box 206 has a clamping groove at the middle of its front end and a threaded hole at the middle of its top front end. A bolt 207 is rotatably connected to the threaded hole of the screening box 206. The bottom of the bolt 207 is located in the clamping groove of the screening box 206. The rear end of the sliding rod 205 is inserted into the clamping groove of the screening rack 2, and the bottom of the bolt 207 is attached to the top rear end of the sliding rod 205.

[0037] When using:

[0038] Place the goji berries to be dried and preserved into the screening box 206. Place the screening box 206 inside the rear end of the screening rack 2. Insert the rear end of the sliding rod 205 into the clamping groove at the front end of the screening box 206. Rotate the bolt 207 so that the bottom position fits against the sliding rod 205, and fix the rear end of the sliding rod 205 to the screening box 206.

[0039] The entire screening rack 2 is placed at the top front end of the strip conveyor belt 102. The strip conveyor belt 102 drives the screening rack 2 to a rearward position. The screening rack 2 contacts the front door of the low-temperature vacuum drying oven 105. Due to the force of the moving strip conveyor belt 102, the front door of the low-temperature vacuum drying oven 105 will rotate inward. After the screening rack 2 has completely passed through the front door of the low-temperature vacuum drying oven 105 and is inside the low-temperature vacuum drying oven 105, the front door of the low-temperature vacuum drying oven 105 will elastically reset and close, thus achieving low-temperature vacuum drying. The drying oven 105 is a relatively sealed space. When the vacuum pump 104 and the control unit 103 are started, the vacuum pump 104 starts working, creating a vacuum environment inside the low-temperature vacuum drying oven 105. The goji berries are dried under low-temperature vacuum conditions. The vacuum environment lowers the boiling point of water, allowing the fresh goji berries to dehydrate rapidly at a low temperature of 30-40℃. This method avoids the damage of high temperatures to active ingredients such as carotenoids and goji polysaccharides, while protecting the natural wax layer on the surface of the fruit. This makes the dried fruit have a color and plumpness similar to that of the fresh fruit, achieving the effect of locking in the freshness of the goji berries.

[0040] At the same time, the motor 202 is started, and the shaft of the motor 202 drives the U-shaped frame 203 to rotate. The middle protrusion of the U-shaped frame 203 rotates with the front end of the transmission rod 204, and the transmission rod 204 moves accordingly, causing the sliding rod 205 to slide back and forth at the rear end of the control frame 201. The screening box 206 reciprocates at the rear end of the screening frame 2, and the goji berries are constantly turned over in the screening box 206. During the turning process, impurities and unqualified fruits fall through the through part in the middle of the screening frame 2 and fall through the gap of the strip conveyor belt 102 into the receiving rack 101 for temporary storage.

[0041] In addition, during the reciprocating movement of the screening box 206 inside the screening rack 2, the goji berries are constantly turned over inside the screening box 206, which can achieve a turning effect in the drying process of the low temperature vacuum drying oven 105, ensuring uniform drying of the goji berries and improving the efficiency of freshness-locking drying of goji berries.
