Description

Technical Field

[0001] The present invention relates to a detection device, in particular to a detection device for testing the dehydration rate of freeze-dried food, belonging to the technical field of freeze-dried food detection. Background Art

[0002] Freeze-dried food is short for vacuum freeze-dried food, also known as FD food. Due to this special processing process of freeze-drying, the original fresh food can be maximally maintained in terms of color, aroma, taste, nutritional components, appearance shape, etc.; in addition, freeze-dried products can be stored at room temperature for more than 5 years without preservatives, and the finished products are light in weight, convenient to carry and transport, which is an excellent method for processing tourism, leisure and convenience foods. After the freeze-dried food is produced, in order to ensure that the freeze-dried food can be stored for a long time subsequently, a moisture meter is usually used to detect the dehydration rate of the freeze-dried food, with simple operation and accurate testing.

[0003] In the prior art, during the process of using a moisture meter by staff to detect the dehydration rate of freeze-dried food, the staff need to manually place the freeze-dried food to be detected on the weighing pan, and in order to facilitate the subsequent heating and drying of the freeze-dried food in the weighing pan, the staff also need to manually flatten the freeze-dried food in the weighing pan. Finally, the staff still need to manually place the weighing pan into the moisture meter. If multiple types of freeze-dried food need to be detected, but the weighing pan after being heated cannot be manually taken by the staff and can only be used after cooling, resulting in the staff being unable to quickly process the freeze-dried food detected in the weighing pan and place the subsequent freeze-dried food to be detected in the weighing pan, greatly reducing the detection efficiency of detecting the dehydration rate of multiple types of freeze-dried food. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the prior art and propose a detection device for testing the dehydration rate of freeze-dried food.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A detection device for testing the dehydration rate of freeze-dried food includes a device body. A weighing pan is placed on the top of the device body. A bracket is sleeved on the outer wall of the weighing pan. A heating cylinder is hinged to the top of the device body. A taking mechanism for automatically taking the weighing pan is provided on one outer wall of the device body. The taking mechanism includes a mounting seat arranged on one side of the device body. Clamping blocks for clamping and fixing one end of the bracket are provided at both ends of the mounting seat. A receiving groove for receiving the taking mechanism is opened at the bottom of the device body. Two telescopic plates for blocking the bottom of the receiving groove are installed inside the receiving groove.

[0007] Optionally, a first sliding groove is formed in an outer wall of one side of the device body, a first electric slider is installed inside the first sliding groove, and a first rotating seat is installed at one end of the first electric slider away from the first sliding groove.

[0008] Optionally, a first rotating block is rotatably installed inside the first rotating seat, a first electric telescopic rod is installed on an outer wall of one side of the first rotating block away from the first rotating seat, and an extending end of the first electric telescopic rod is connected to a second rotating seat.

[0009] Optionally, a second rotating block is rotatably installed inside the second rotating seat, a second electric telescopic rod is installed on an outer wall of one side of the second rotating block away from the second rotating seat, and an extending end of the second electric telescopic rod is rotatably connected to a bottom end of the mounting seat through a first rotating shaft.

[0010] Optionally, third rotating blocks are rotatably installed at both ends of the mounting seat, and outer walls of one side of the two third rotating blocks away from the mounting seat are connected to clamping blocks close to them through second rotating shafts.

[0011] Optionally, a first cleaning pad is installed on a top of the mounting seat, and second cleaning pads are installed on tops of the two clamping blocks.

[0012] Optionally, a fixing plate is installed on an outer wall of one side of the mounting seat, rotating plates are rotatably installed at both ends of the fixing plate, a folding protection curtain is jointly installed on a top of the fixing plate and outer walls of one side of the two rotating plates away from each other, and scraping plates are installed on outer walls of one side of the two rotating plates away from each other.

[0013] Optionally, second sliding grooves are formed in inner parts of opposite sides of the storage groove, and one ends of the two telescopic plates close to each other slide back and forth in the second sliding grooves through second electric sliders.

[0014] Optionally, convex portions are installed on outer walls of opposite sides of the device body close to the storage groove, and limiting members are slidably installed on tops of the convex portions.

[0015] Optionally, limiting grooves are formed in tops of the two telescopic plates close to the second sliding grooves, and the limiting grooves are slidably adapted to the limiting members.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In this invention, through the taking mechanism arranged on one side of the device body, with the cooperation between various components of the taking mechanism, the weighing pan can be automatically taken, enabling the device body to adapt to the efficiency of detecting various freeze-dried foods, and subsequent freeze-dried foods can be detected without waiting for the weighing pan to cool.

[0018] 2. In this invention, a storage groove is provided at the bottom of the device body. When the device body is not in use, the taking mechanism can be rotated and stored in the storage groove, which is convenient for reducing the volume of the device body and facilitating the storage of the device body.

[0019] 3. In this invention, after placing the freeze-dried food to be detected on the weighing pan, the two clamping blocks can be used to clamp and fix one end of the bracket. By means of the reciprocating telescoping of the first electric telescopic rod, the freeze-dried food in the weighing pan is driven to vibrate back and forth, so that the freeze-dried food can be automatically flattened in the weighing pan without manual flattening by the staff. During the heating process of the freeze-dried food in the weighing pan, the weighing pan can continue to be driven to vibrate by the first electric telescopic rod, so that the freeze-dried food in the weighing pan is heated and dried more evenly, improving the detection efficiency.

[0020] 4. In this invention, after detecting the oily freeze-dried food, since the freeze-dried food contains oil inside and some oil will overflow into the weighing pan after being heated in the device body. In order to facilitate the subsequent detection of other freeze-dried foods, the weighing pan can be placed on the top of the telescopic plate, and the second rotating block is controlled to rotate downward in the second rotating seat, driving the second electric telescopic rod and the components such as the mounting seat and the clamping blocks on its top to rotate downward into the weighing pan together. After driving the outer wall of the side of the two clamping blocks with the second cleaning pad to rotate close to the inner bottom surface of the weighing pan, at this time, the first rotating shaft at the extending end of the second electric telescopic rod can be used to drive the mounting seat and the two clamping blocks to rotate in the weighing pan, so that the first cleaning pad and the second cleaning pad can clean the oil on the inner bottom surface of the weighing pan during the rotation process, avoiding the problem that the oil solidifies and is inconvenient to clean after the weighing pan cools down.

[0021] 5. In this invention, when the heating cylinder is damaged and needs to be repaired, the opening at the top of the device body is in an open state at this time. In order to avoid dust or parts falling into the opening during the repair of the heating cylinder and affecting the operation of the precision components inside the device body, the electric slider can be controlled to slide downward in the first chute to a specified position, and then the first rotating block is controlled to rotate upward 90 degrees in the first rotating seat, driving the second electric telescopic rod and the multiple components at its extending end to rotate above the device body together. Then, the folding protective curtain can be controlled to be in an unfolded state, so that the unfolded folding protective curtain can block the opening at the top of the device body, avoiding the situation that foreign dust or sundries easily fall into the opening after the opening at the top of the device body loses the block of the heating cylinder.

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0035] Referring to Figures 1 - 10 , a detection device for testing the dehydration rate of freeze-dried food, including a device body 1, a weighing pan 3 is placed on the top of the device body 1, a bracket 6 is sleeved on the outer wall of the weighing pan 3, a heating cylinder 2 is hinged to the top of the device body 1, and a taking mechanism for automatically taking the weighing pan 3 is provided on the outer wall of one side of the device body 1. The taking mechanism includes a mounting seat 18 provided on one side of the device body 1, and clamping blocks 19 for clamping and fixing one end of the bracket 6 are provided at both ends of the mounting seat 18. A receiving groove 5 for receiving the taking mechanism is opened at the bottom of the device body 1, and two telescopic plates 4 for sealing the bottom of the receiving groove 5 are installed inside the receiving groove 5.

[0036] As a technical optimization scheme of the present invention, a first sliding groove 7 is opened on the outer wall of one side of the device body 1, a first electric slider 14 is installed inside the first sliding groove 7, and a first rotating seat 15 is installed at the end of the first electric slider 14 away from the first sliding groove 7.

[0037] As a technical optimization scheme of the present invention, a first rotating block is rotatably installed inside the first rotating seat 15, a first electric telescopic rod 17 is installed on the outer wall of the first rotating block away from the first rotating seat 15, and the extending end of the first electric telescopic rod 17 is connected to a second rotating seat 21. The first rotating block can drive the first electric telescopic rod 17 and the second rotating seat 21 to rotate together inside the first rotating seat 15.

[0038] As a technical optimization scheme of the present invention, a second rotating block is rotatably installed inside the second rotating seat 21, a second electric telescopic rod 13 is installed on the outer wall of the second rotating block away from the second rotating seat 21, and the extending end of the second electric telescopic rod 13 is rotatably connected to the bottom end of the mounting seat 18 through a first rotating shaft. The second rotating block can drive the second electric telescopic rod 13 and components such as the mounting seat 18 installed on its top to rotate together inside the second rotating seat 21, and the extending end of the second electric telescopic rod 13 is rotatably connected to the mounting seat 18 through a first rotating shaft, so that the mounting seat 18 can rotate on the top of the second electric telescopic rod 13.

[0039] As a technical optimization solution of the present invention, third rotating blocks 27 are rotatably installed at both ends of the mounting seat 18, and the outer walls of the two third rotating blocks 27 away from the mounting seat 18 are connected to the clamping blocks 19 close to them through second rotating shafts. The two clamping blocks 19 can rotate at both ends of the mounting seat 18 through the two third rotating blocks 27, and the two clamping blocks 19 can also rotate on the third rotating blocks 27 through the second rotating shafts.

[0040] As a technical optimization solution of the present invention, a first cleaning pad 22 is installed on the top of the mounting seat 18, and second cleaning pads 23 are installed on the tops of the two clamping blocks 19. The first cleaning pad 22 and the two second cleaning pads 23 can cooperate with each other to clean the inner bottom surface of the weighing pan 3, which is convenient for the subsequent use of the weighing pan 3.

[0041] As a technical optimization solution of the present invention, a fixing plate 20 is installed on the outer wall of one side of the mounting seat 18. Rotating plates 25 are rotatably installed at both ends of the fixing plate 20. A folding protective curtain 24 is jointly installed on the top of the fixing plate 20 and the outer walls of the two rotating plates 25 away from each other. Scrapers 26 are installed on the outer walls of the two rotating plates 25 away from each other. The provided folding protective curtain 24 can block the opening at the top of the device body 1. The scrapers 26 on the outer walls of the two rotating plates 25 can clean the arc-shaped inner wall of the weighing pan 3 while the first cleaning pad 22 and the second cleaning pads 23 clean the bottom of the weighing pan 3.

[0042] As a technical optimization solution of the present invention, second sliding grooves 9 are opened in the inner parts of the two opposite sides of the storage groove 5, and one ends of the two telescopic plates 4 close to each other slide back and forth in the second sliding grooves 9 through second electric sliders 11.

[0043] As a technical optimization solution of the present invention, convex parts are installed on the outer walls of the two sides of the device body 1 close to the opposite sides of the storage groove 5. Limiting parts 8 are slidably installed on the tops of the convex parts. Limiting grooves 12 adapted to the limiting parts 8 are opened at the tops of the two telescopic plates 4 close to the second sliding grooves 9.

[0044] As a technical optimization solution of the present invention, limiting grooves 12 are opened at the tops of the two telescopic plates 4 close to the second sliding grooves 9, and the limiting grooves 12 are slidably adapted to the limiting parts 8. The two telescopic plates 4 can slide back and forth in the second sliding grooves 9 through the second electric sliders 11, and then can drive the two telescopic plates 4 to move back and forth in the second sliding grooves 9 together, which is convenient for the telescopic plates 4 in the extended state to provide a placement platform for the weighing pan 3.

[0045] In the present invention, when the user uses the device, the freeze-dried food to be detected can be placed on the weighing pan 3 for weighing. After the weighing is completed, the two third rotating blocks 27 can be controlled to rotate towards the bracket 6 at both ends of the mounting seat 18, driving the two clamping blocks 19 to rotate synchronously towards each other. At the same time when the two clamping blocks 19 rotate towards each other, the two second rotating shafts are controlled to rotate, so that the two clamping blocks 19 can rotate respectively with the second rotating shafts as the centers until the sides of the two clamping blocks 19 equipped with the second cleaning pads 23 both rotate to the side close to the bracket 6. At this time, the two clamping blocks 19 can clamp the bracket 6 more tightly with the help of the two second cleaning pads 23 respectively.

[0046] After the two clamping blocks 19 cooperate with the two second cleaning pads 23 to clamp and fix one end of the bracket 6, the extending end of the first electric telescopic rod 17 can be controlled to stretch back and forth, driving the second rotating seat 21, the second rotating block, the second electric telescopic rod 13 and the mounting seat 18 and the clamping block 19 mounted on its top to move back and forth together. Furthermore, the bracket 6 and the weighing pan 3 can be driven to shake back and forth in the opening at the top of the device body 1, so that the freeze-dried food located inside the weighing pan 3 can be automatically flattened during the shaking process. Then, after covering the heating cylinder 2 on the top of the device body 1, the freeze-dried food inside the weighing pan 3 can be heated and dried to detect whether the dehydration rate of the freeze-dried food is qualified. While heating the freeze-dried food inside the weighing pan 3, the extending end of the first electric telescopic rod 17 can be continuously driven to stretch back and forth, driving the weighing pan 3 to continue shaking, so that the freeze-dried food being heated and dried can be heated more evenly, which is convenient for improving the detection efficiency.

[0047] After the freeze-dried food in the weighing pan 3 is detected, since the surface temperature of the weighing pan 3 after heating is too high, the staff cannot quickly take out the weighing pan 3 and take out the detected freeze-dried food inside the weighing pan 3. At this time, the second rotating block can be rotated downward away from the device body 1 in the second rotating seat 21, driving the bracket 6 clamped by the two clamping blocks 19 and the weighing pan 3 inside the bracket 6 to be rotated out of the inside of the device body 1 together, and pouring out the detected freeze-dried food inside the weighing pan 3, achieving the effect of automatically taking out the weighing pan 3 and the detected freeze-dried food inside it.

[0048] If the surface of the freeze-dried food to be detected is relatively clean, after taking it out, the second rotating block can be controlled to rotate and reset in the second rotating seat 21, driving the weighing pan 3 to return to the opening of the device body 1 again, which is convenient for continuously detecting the subsequent freeze-dried food to be detected; if the internal of the freeze-dried food to be detected contains oil, after this part of the freeze-dried food is placed in the weighing pan 3 for detection, the inside of the weighing pan 3 will inevitably be attached with the oil generated by heating. The surface temperature of the weighing pan 3 after being heated is too high, and the staff needs to wait for the weighing pan 3 to cool down before cleaning its inside. However, waiting for the weighing pan 3 to cool down and then cleaning its inside and then detecting the subsequent freeze-dried food will inevitably affect the detection efficiency. Moreover, due to the oil generated by the heating of the freeze-dried food containing oil inside the weighing pan 3, the oil will also solidify after the weighing pan 3 cools down, making it more inconvenient for the staff to clean it up.

[0049] In such a situation, after discharging the freeze-dried food in the weighing pan 3 that has passed the detection, the weighing pan 3 can be controlled to reset, and then the first electric slider 14 is controlled to move upward in the first chute 7, driving the second electric telescopic rod 13, the mounting seat 18 at its top, and the two clamping blocks 19 to move upward together. Furthermore, the bracket 6 and the weighing pan 3 clamped by the two clamping blocks 19 are driven to move upward above the opening at the top of the device body 1. Then, the first rotating shaft can be controlled to drive the mounting seat 18 to rotate 180 degrees together, which can drive the weighing pan 3 to rotate to a position away from the device body 1. Then, the telescopic plate 4 below the first electric slider 14 can be controlled to extend to the maximum length, and its extended end is located below the weighing pan 3. When the clamping of the bracket 6 by the two clamping blocks 19 is cancelled, the weighing pan 3 automatically drops downward to the top of the telescopic plate 4 in the extended state. At this time, the two clamping blocks 19 are controlled to rotate to a state in the same straight line as the mounting seat 18, and at the same time, the outer walls of the two clamping blocks 19 with the second cleaning pads 23 installed are controlled to rotate to the top, so that the first cleaning pad 22 and the two second cleaning pads 23 are on the same horizontal plane. Then, the first electric slider 14 can be controlled to move upward to the top end of the first chute 7, and the second rotating block is controlled to rotate downward 180 degrees in the second rotating seat 21, thereby driving the second electric telescopic rod 13, the mounting seat 18, and the two clamping blocks 19 to rotate to a position close to the telescopic plate 4. Then, the extended end of the second electric telescopic rod 13 that was originally in the extended state can be controlled to contract, driving the mounting seat 18 and the two clamping blocks 19 connected to the extended end of the second electric telescopic rod 13 to move upward a certain distance. Finally, the second electric slider 11 can be controlled to move in the second chute 9, driving the telescopic plate 4 in the extended state at this time and the weighing pan 3 placed on its top to move to the lower part of the mounting seat 18. The extended end of the second electric telescopic rod 13 is controlled to extend again, so that the mounting seat 18 and the two clamping blocks 19 move downward into the weighing pan 3 together until the first cleaning pad 22 and the two second cleaning pads 23 contact the inner bottom surface of the weighing pan 3. The first rotating shaft is controlled to rotate, driving the mounting seat 18 and the two clamping blocks 19 to rotate in the weighing pan 3, so that the melted grease on the inner bottom surface of the weighing pan 3 can be cleaned and adsorbed by the rotating first cleaning pad 22 and the two second cleaning pads 23, avoiding the problem that the grease inside the weighing pan 3 solidifies after cooling and is inconvenient to clean.

[0050] Meanwhile, after the mounting seat 18 and the two clamping blocks 19 extend into the weighing pan 3, the fixing plate 20 and the rotating plate 25 installed on the outer wall of one side of the mounting seat 18 can be driven to move into the weighing pan 3 synchronously. Since scraping plates 26 are installed on the mutually remote sides of the two rotating plates 25, when the first rotating shaft in the mounting seat 18 drives the rotation, the two scraping plates 26 can be driven to scrape the arc-shaped inner wall of the weighing pan 3 synchronously, cleaning the grease adhered to its inner wall.

[0051] When the heating cylinder 2 at the top of the device body 1 is damaged and needs to be repaired, the opening position at the top of the device body 1 is in an open state. To prevent the opening from being in an open state and for external dust or debris from falling into the interior of the device body 1, at this time, the first electric slider 14 can be controlled to move upward in the first chute 7 to a specified position, and then the first rotating block 16 can be controlled to rotate upward 90 degrees in the first rotating seat 15, driving the second electric telescopic rod 13 to rotate upward to the top of the device body 1, and driving the mounting seat 18 and the two clamping blocks 19 to be in a horizontal state at the top of the device body 1. After controlling the two rotating plates 25 to rotate to a state where they are in the same straight line as the fixed plate 20, and then controlling the folding protective curtain 24 to be in a fully unfolded state, the opening part at the top of the device body 1 can be covered by the unfolded folding protective curtain 24 to protect the opening at the top of the device body 1 and prevent dust or debris from entering the interior of the device body 1 through the opening and affecting the normal operation of the precision components inside the device body 1.

[0052] After the detection work of the freeze-dried food by the device body 1 is completed, the second rotating block can be controlled to rotate downward 90 degrees in the second rotating seat 21, so that the second electric telescopic rod 13 and the components on its top rotate to a horizontal state together. Control the two telescopic plates 4 to move towards the other end through the second electric slider 11 in the second chute 9, and then control the first rotating block 16 to rotate towards the storage groove 5 in the first rotating seat 15, so that components such as the mounting seat 18 can be stored in the storage groove 5 when not in use, reducing the volume of the device body 1 and facilitating the storage of the device body 1; and after the components such as the mounting seat 18 rotate into the storage groove 5, control the two telescopic plates 4 to reset, and the components such as the mounting seat 18 located at the bottom of the device body 1 can be protected.

Obviously, according to the content of this specification, many modifications and changes can be made.
