Description

Technical Field

[0001] This invention relates to the field of wolfberry seed processing equipment technology, and in particular to a wolfberry seed ripening equipment. Background Technology

[0002] Goji berries are a unique Chinese economic crop with both medicinal and edible uses. Goji berry seeds are a major byproduct of the deep processing of goji berries, including juice extraction, drying, and polysaccharide extraction. They are rich in unsaturated fatty acids, goji berry pigments, polysaccharides, and flavonoid active ingredients. After ripening, their aroma, flavor, and nutrient extraction efficiency can be significantly improved, making them an important raw material for high-end edible vegetable oils, meal replacement powders, and functional health foods. With the extension of the goji berry deep processing industry chain, the demand for large-scale processing of goji berry seeds continues to grow, placing higher demands on the continuity of production, the uniformity of finished products, material loss rates, and hygiene of the ripening process.

[0003] Currently, the industry mostly uses the same mesh belt hot air ripening equipment commonly used for grains and oilseeds for ripening goji berries. This type of equipment mainly generates hot airflow through heating elements inside the shell, which, combined with a multi-layer conveyor belt, moves the material forward, and the moisture is discharged through a top dehumidification mechanism, achieving continuous ripening. However, due to the characteristics of goji berries—small particle size, high oil content, and the tendency for oil to seep out and adhere when heated—existing general equipment suffers from the following insurmountable technical defects in practical applications: First, during the initial heating and ripening process on the first layer of the conveyor belt, the oil on the surface of the seeds seeps out, easily causing adjacent seeds to clump together and form unevenly sized clumps. Existing multi-layer mesh belt equipment relies solely on the gravity difference of the falling material for turning, and cannot break up the clumps; if an additional rigid stirring and dispersing mechanism is added, it easily causes seed breakage, reducing the integrity rate of the finished product and increasing material loss. The internal heat conduction of the grains within the agglomerates is hindered, easily leading to "outer cooking and inner stagnation." Meanwhile, the surface grains become charred and carbonized due to prolonged heating, severely impacting the stability of the finished product's quality. Secondly, the oils seeping out due to heat and grain surface debris continuously adhere to the conveyor belt surface, gradually carbonizing under high temperatures to form a stubborn scale layer. On one hand, this scale layer clogs the ventilation pores of the conveyor belt, reducing hot air penetration efficiency and further exacerbating uneven heating of the material layer; on the other hand, the carbonized scale easily detaches and mixes into the finished product, lowering its hygiene level. Existing equipment generally uses manual scraping and cleaning during shutdown, which not only interrupts the production process and reduces efficiency but also relies on manual operation, resulting in inconsistent cleaning effectiveness.

[0004] Therefore, it is necessary to provide a new goji berry ripening device to solve the above-mentioned technical problems. Summary of the Invention

[0011] Preferably, the cleaning assembly includes: a second motor, a key shaft, and a key sleeve. The second motor is fixedly connected to the side wall of the housing near the cleaning brush.

[0016] Compared with related technologies, the wolfberry seed ripening equipment provided by this invention has the following beneficial effects:

[0017] 1. The design of the drive component enables the kneading board to perform a cyclical motion of "moving down - rotating and kneading - lifting," which completely breaks down the unevenly sized clumps of goji berry seeds that form after the initial ripening process into individual seeds. Simultaneously, the spring buffer structure counteracts rigid compressive force, preventing the seeds from being crushed or damaged, thus improving the integrity rate of the finished product. After the clumps are broken up, the seeds can be fully heated, eliminating the "outer ripening, inner stunting" phenomenon and localized scorching from the outset, significantly improving the stability of the finished product's quality.

[0018] 2. Through the design of the cleaning components, the cleaning brush continuously rotates and brushes the belt surface under the drive of motor two. At the same time, through the sliding cooperation of the key shaft and key sleeve, the electric push rod two drives the cleaning brush to move back and forth along the width of the conveyor belt, realizing the brushing of the entire width and all pores of the conveyor belt without dead angles, thoroughly removing the adhering grease, debris and initial carbonized scale layer, avoiding the blockage of the air pores of the conveyor belt by the scale layer, maintaining stable hot air penetration efficiency, and eliminating the risk of carbonized scale material falling off and mixing into the finished product, which greatly improves the hygiene level of the finished product.

[0019] 3. While the electric push rod is running, it drives the material plate to slide back and forth at a constant speed along the crossbar, spreading the kneaded and dispersed material evenly onto the surface of the lower conveyor belt, eliminating local accumulation and protrusion of the material layer caused by gravity falling, and ensuring that the material layer thickness is uniform throughout the secondary curing process.

[0020] 4. Separate negative pressure collection channels are set up for the kneading and cleaning stations, and the debris and dust are centrally treated through negative pressure pumps and collection boxes. On the one hand, the negative pressure holes at the kneading plate can suck away the surface debris and fine dust generated during the kneading process in real time, preventing impurities from mixing into the finished material; on the other hand, the arc-shaped cover at the cleaning brush can absorb and collect the oil and debris that fall off the brush in real time, preventing debris from falling again and contaminating the lower layer of material, effectively reducing the accumulation of dirt inside the equipment, and preventing dust from spreading into the workshop environment with the exhaust airflow, greatly reducing the cost of equipment cleaning and maintenance.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] Example 1

[0033] Please see Figures 1 to 7A goji berry seed ripening device includes: a shell 1, a conveyor belt 5, a kneading plate 6, a drive assembly, a cleaning brush 7, a cleaning assembly, and a heating element 2 installed at the bottom of the shell 1, and a dehumidification mechanism 3 installed at the top of the shell 1. The heating element 2 is an electric heating tube, which, together with a circulating fan inside the shell 1, forms a bottom-up hot air circulation, with the hot air penetrating the mesh belt to heat the material layer. The dehumidification mechanism 3 is a dehumidification fan with a regulating valve, which is linked to a temperature and humidity sensor inside the shell 1. The dehumidification volume is automatically adjusted by a control box 31 to maintain stable temperature and humidity inside the cavity. Conveyor belts 4 are symmetrically installed inside the shell 1. The two conveyor belts 4 are arranged in parallel layers, both using food-grade stainless steel perforated mesh belts with an opening ratio that meets the requirements for hot air penetration. Both conveyor belts 4 are driven by independent speed-regulating motors. The directions are opposite; the upper conveyor belt 4 has a transfer belt 5 at the end away from the feeding end, and a kneading plate 6 is provided above the transfer belt 5. The bottom surface of the kneading plate 6 is made of food-grade flexible wear-resistant material, and the surface has an interlaced arc-shaped raised texture to ensure the kneading effect while avoiding scratching the seeds. A drive component is installed between the transfer belt 5 and the kneading plate 6. The drive component drives the kneading plate 6 to move down and rotate to knead the goji berry seeds after the initial ripening. A cleaning brush 7 is provided at the bottom of the upper conveyor belt 4 away from the feeding end. A cleaning component is installed between the cleaning brush 7 and the conveyor belt 4. The cleaning component drives the cleaning brush 7 to rotate to clean the surface of the upper conveyor belt 4. A material distribution plate 8 is provided above the lower conveyor belt 4 near the feeding end. The material distribution plate 8 is an inclined material distribution plate with guide teeth evenly distributed on the plate surface.

[0034] The drive assembly includes: an electric push rod 9, a drive plate 10, and a guide rod 11. A mounting cover 12 is fixedly connected to the end of the housing 1 away from the feeding end.

The guide rod 11 is fixedly connected to the inner wall of the other side of the mounting cover 12. The other end of the drive plate 10 is slidably sleeved on the outer wall of the guide rod 11.

[0035] A motor 13 is fixedly connected to the top center of the drive plate 10. Its output end passes through the bottom of the drive plate 10 and is fixedly connected to a rotating plate. A sleeve 14 is fixedly connected to the bottom of the other end of the rotating plate. A spring 15 is fixedly connected to the inner wall of the sleeve 14. A slide rod 16 is fixedly connected to the other end of the spring 15. The bottom end of the slide rod 16 is fixedly connected to the top center of the kneading plate 6. The sleeve 14 and the slide rod 16 are in a spline sliding fit (circumferentially limited and axially sliding) to ensure that the rotational torque can be stably transmitted to the kneading plate 6. A limit ring is set at the bottom end of the sleeve 14 to prevent the slide rod 16 from coming out, thus achieving reliable flexible buffering. The motor 13 drives the rotating plate to rotate, causing the kneading plate 6 to revolve around the motor axis. This, combined with the lifting action, achieves the kneading and breaking up of the material layer.

[0036] The ends of the shafts at both ends of the transfer belt 5 are rotatably connected to the inner wall of the mounting cover 12. An inclined guide plate 19 is fixedly connected to the inner wall of the end of the housing 1 away from the feeding end. One end of the guide plate 19 contacts the outer wall of the upper conveyor belt 4 near the unloading end. The other end of the guide plate 19 is located above the transfer belt 5. A drive pulley 17 is fixedly connected to the end of the shaft of the upper conveyor belt 4 away from the feeding end. A driven pulley 18 is fixedly connected to the end of the shaft of the transfer belt 5 near the upper conveyor belt 4. The drive pulley 17 and the driven pulley 18 are connected by belt drive.

The L-shaped guide plate 20 is located below the end of the transfer belt 5 away from the upper conveyor belt 4, and the bottom end of the L-shaped guide plate 20 is located above the fabric plate 8. Two crossbars 21 are fixedly connected to the bottom inner wall of the mounting cover 12. Corresponding collars to the crossbars 21 are symmetrically fixedly connected to the bottom of the fabric plate 8, and the collars are slidably sleeved on the outer wall of the corresponding crossbars 21.

[0038] Example 2

[0039] Please see Figure 2 , Figure 6 , Figure 7 and Figure 8 The cleaning assembly includes: a second motor 22, a key shaft 23, and a key sleeve 24. The second motor 22 is fixedly connected to the side wall of the housing 1 near the cleaning brush 7. The output end of the motor 22 is fixedly connected to the key shaft 23 through the inner wall of the housing 1. The key sleeve 24 is slidably sleeved on the outer wall of the key shaft 23. The cleaning brush 7 is fixedly sleeved on the outer wall of the key sleeve 24. The outer wall of the cleaning brush 7 is provided with bristles, and the bristles are in contact with the bottom outer wall of the upper conveyor belt 4. The length of the cleaning brush 7 is the same as the length of the fabric plate 8.

[0040] An electric push rod 25 is fixedly connected to the side wall of the mounting cover 12. Its output end extends into the interior of the mounting cover 12 and is fixedly connected to a transmission rod 26. A connecting rod 1 is fixedly connected to both sides of the fabric plate 8. The other end of the connecting rod 1 is fixedly connected to the outer wall of the transmission rod 26. The outer walls of both ends of the key sleeve 24 are rotatably fitted with a connecting rod 2. The other end of the connecting rod 2 is fixedly connected to the outer wall of the transmission rod 26.

[0041] The top of the rubbing board 6 is symmetrically fixed with a negative pressure cover 27. The bottom of the rubbing board 6 has negative pressure holes equidistantly opened in the area corresponding to the negative pressure cover 27. The top of the negative pressure cover 27 is rotatably connected to a connecting pipe. The other end of the connecting pipe extends out of the mounting cover 12. The connecting pipe and the negative pressure cover 27 are rotatably connected through a rotary sealing joint to ensure that the negative pressure circuit is continuously sealed and leak-free during the rotation of the rubbing board 6.

[0042] A curved cover 28 is provided on one side of the cleaning brush 7. The curved cover 28 is a semi-enclosed cover with its opening facing the bristles of the cleaning brush 7. It is arranged along the entire length of the cleaning brush 7 to cover all the debris that falls off into the suction range and prevent the debris from falling off again. Both ends of the curved cover 28 are fixedly connected to the corresponding connecting rods. A negative pressure pipe is connected to the middle of the curved cover 28. The other end of the negative pressure pipe extends out of the mounting cover 12. A negative pressure pump 29 is fixedly connected to the side wall of the mounting cover 12. The end of the connecting pipe extending out of the mounting cover 12 and the end of the negative pressure pipe extending out of the mounting cover 12 are both connected to the input end of the negative pressure pump 29. The output end of the negative pressure pump 29 is connected to the collection box 30.

[0043] A hopper is fixedly connected to the top of the end of the housing 1 away from the mounting cover 12, a discharge plate is fixedly connected to the side wall of the end of the housing 1 away from the mounting cover 12, and a control box 31 is fixedly connected to the side wall of the housing 1.

[0044] The working principle of the wolfberry seed ripening equipment provided by this invention is as follows:

[0045] After the equipment is started, the control box 31 first issues a preheating command. The heating element 2 at the bottom of the shell 1 is energized and heated to preheat the inner cavity of the shell 1. At the same time, the dehumidification mechanism 3 at the top of the shell 1 is simultaneously activated and put into standby mode to maintain the airflow circulation path in the cavity. At this time, the electric push rod 9 is in the extended state, driving the drive plate 10 to rise to the highest position along the guide rod 11. The rubbing plate 6 and the surface of the conveyor belt 5 maintain a safe distance. The electric push rod 25 is in the initial center position, and the cloth plate 8 and the cleaning brush 7 are both located at the center of the width. Each drive motor is in standby mode, completing the initialization preparation before the equipment runs.

[0046] After preheating to the set temperature, the hopper opens to discharge the goji berry seeds, which fall evenly onto the upper conveyor belt 4. The upper conveyor belt 4 operates at a constant speed under the drive motor, moving the material horizontally towards the heating area inside the housing 1. The heat generated by the heating element 2 penetrates the conveyor belt 4 from bottom to top, conducting hot air to heat the material layer, thus completing the initial heating and ripening of the goji berry seeds. After the internal moisture of the seeds evaporates due to heat, it is discharged from the cavity by the top dehumidification mechanism 3 with the airflow. During this stage, the surface oil of the goji berry seeds gradually seeps out due to heat, and adjacent seeds easily clump together to form clumps of varying sizes, which move downwards along with the conveyor belt 4.

[0047] When the upper conveyor belt 4 carrying agglomerated material reaches the unloading end, the material naturally slides down along the inclined guide plate 19 and falls smoothly onto the surface of the transfer belt 5 below. The end shaft of the upper conveyor belt 4 synchronously drives the drive pulley 17 to rotate, which in turn drives the driven pulley 18 to rotate synchronously through belt transmission. This drives the transfer belt 5 to maintain synchronous linear speed with the upper conveyor belt 4, ensuring continuous and stable material transport. At the same time, the electric push rod 9 starts and performs reciprocating motion at a set frequency, driving the drive plate 10 to move axially up and down along the guide rod 11. The motor 13 starts synchronously, and its output end drives the rotating plate to rotate circumferentially. This, in turn, drives the kneading plate 6 to rotate through the sleeve 14, spring 15, and slide rod 16. The lifting and rotating motions are coupled, causing the kneading plate 6 to act on the material layer on the transfer belt 5 in a cyclical motion of "pressing down - rotating and kneading - lifting up," gradually breaking down the initially formed agglomerated clumps into individual particles. During the kneading process, when the kneading board 6 comes into contact with the material, the reaction force of the material pushes the slide bar 16 to slide into the sleeve 14, compressing the internal spring 15 to form a flexible buffer, avoiding rigid extrusion that could cause the grains to break, and ensuring the integrity of the finished product.

[0048] During the entire operation of the upper conveyor belt 4, the cleaning components simultaneously perform belt surface cleaning: Motor 22 continuously operates, driving the key shaft 23 to rotate. Through key engagement, the key sleeve 24 rotates synchronously, causing the cleaning brush 7 to continuously rotate around the axis. The bristles continuously brush the lower surface of the return section of the upper conveyor belt 4, removing grease, surface debris, and carbonized scale adhering to the belt surface. Simultaneously, electric push rod 25 drives the transmission rod 26 to move axially back and forth. Through connecting rod 2, the key sleeve 24 slides axially back and forth along the key shaft 23, causing the cleaning brush 7 to move back and forth along the width of the conveyor belt 4 while rotating. This achieves thorough cleaning of the entire width and all areas of the upper conveyor belt 4 without dead angles, preventing blockage of belt gaps from affecting the hot air penetration effect.

[0049] After being kneaded and broken up, the goji berry seeds are transported by the conveyor belt 5 to the unloading end, where they fall naturally onto the surface of the L-shaped guide plate 20. Guided by the guide plate, they fall onto the lower distribution plate 8. Simultaneously, the electric push rod 25 drives the transmission rod 26 in reciprocating motion, and through the connecting rod 1, it drives the distribution plate 8 to slide axially along the two crossbars 21. The collar at the bottom of the distribution plate 8 slides smoothly along the crossbars 21, ensuring that the material falling onto the distribution plate 8 is evenly spread onto the loading end of the lower conveyor belt 4, eliminating material buildup caused by gravity and ensuring a uniform thickness of the lower layer. After the material is spread, the lower conveyor belt 4 carries the material at a uniform speed through the heating zone, performing secondary heating and ripening on the broken goji berry seeds, ensuring even heating inside and out and completely eliminating the "outer ripe, inner raw" phenomenon. When the material reaches the unloading end of the lower conveyor belt 4, the finished product, having completed the entire ripening process, is discharged from the equipment along the discharge plate and enters the next process.

[0050] Throughout the entire process of kneading, breaking up, and cleaning the dough, the negative pressure pump 29 starts simultaneously to generate negative pressure suction, which is then collected in two independent streams:

[0051] The first negative pressure is transmitted through the connecting pipe to the negative pressure cover 27 at the top of the kneading plate 6. The negative pressure hole at the bottom of the kneading plate 6 forms a suction airflow, which sucks away the surface debris and fine dust generated during the kneading process in real time, preventing debris from mixing into the finished product.

[0052] The second negative pressure is transmitted to the arc-shaped cover 28 through the negative pressure pipe, which draws out the oil and debris brushed off by the cleaning brush 7 in real time to prevent the debris from falling again and contaminating the lower layer materials. The two dust-laden airflows are finally converged at the output end of the negative pressure pump 29 and discharged into the collection box 30 for centralized collection. Regular cleaning is sufficient to maintain the cleanliness of the equipment and reduce the unorganized spread of dust.
