Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dryers, in particular to a food dryer. Background Art
[0002] Food refers to substances that supply organisms with energy and nutrients. When food needs to be stored for a long time, drying food is a commonly used method to preserve food and prevent it from spoiling. At the same time, some foods can improve their taste and be more convenient to eat after drying. Different foods to be dried vary in size, and even the same food can have different sizes (for example, red dates have different sizes), and there are also different degrees of drying required (for example, beef jerky dried to nine-tenths dry and beef jerky dried to seven-tenths dry).
[0003] The degree of drying determines the taste of the food. When a batch of foods has different sizes and is processed together in a dryer, a long drying time will cause the smaller foods to be dried to a higher degree and have a relatively dry and hard taste; a short drying time will cause the larger foods to be dried to a lower degree and fail to achieve the ideal drying effect.
[0004] When drying two or more foods with different drying degrees or sizes in one dryer, it is necessary to calculate the drying time by oneself, repeatedly open and close the dryer to take out the food, which is rather troublesome. After taking out the food, the internal space of the dryer is left idle, resulting in a waste of resources. When using multiple dryers for drying, when the batch of food is small, the internal space of the dryer will be left idle, leading to a waste of resources. Summary of the Utility Model
[0005] Aiming at the above defects, the purpose of the utility model is to provide a food dryer, which can dry foods with different sizes or different drying degrees simultaneously. When drying foods with different sizes or different drying degrees simultaneously, trays that have reached the specified drying effect can be taken out successively, so that the foods in each tray reach their preset drying ratios. The balance device and the force measuring device are provided so that the quality of the foods on the trays can be monitored in real time. The control panel and the alarm are provided to preset the drying ratio of the foods on a single tray and give an alarm reminder after the foods on a single tray reach the preset drying degree.

Specific embodiments
[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0020] See Figures 1 to 4, the present utility model provides a food dryer, which includes a plurality of balancing devices 5. The balancing device 5 includes a tray 52, a tray support 51, a first connecting rod 53, a rotating shaft 55, a second connecting rod 56, a rolling bearing 54, and a counterweight 57. A positioning pin 512 is provided at the bottom of the tray 52, and a positioning hole 513 is provided on the tray support 51. The tray 52 is placed on the tray support 51, and the tray support 51 is fixed on the first connecting rod 53. The first connecting rod 53 is fixed on the cylindrical side surface of the rotating shaft 55. Rolling bearings 54 are respectively provided at both ends of the rotating shaft 55, and the rolling bearings 54 are fixed on the drying box 3. The second connecting rod 56 is fixed on the rotating shaft 55 and is symmetric with the first connecting rod 53 about the rotating shaft 55. The counterweight 57 is fixed on the second connecting rod 56. The center of gravity of the balancing device 5 is located on the rotating shaft 55, and the overall center of gravity of the balancing device 5 is located on the rotating shaft 55. The rotating shaft 55 provides a supporting force for the balancing device 5. Rolling bearings 54 are respectively provided on both sides of the rotating shaft 55. The outer ring of the rolling bearing 54 is fixed on the rear side wall of the drying box 3, and the inner ring of the rolling bearing 54 is fixed to the rotating shaft 55. When the rotating shaft 55 rotates, the inner ring of the rolling bearing 54 rotates synchronously. The rolling bearing 54 provides a supporting force for the rotating shaft 55. The tray 52 is used to store the food to be dried. The positioning pin 512 at the bottom of the tray 52 and the positioning hole 513 of the tray support 51 are used to position the tray 52 to be placed, preventing the position of the tray 52 placed each time from being inconsistent, resulting in the deviation of the center of gravity of the balancing device 5 and affecting the drying result. The first connecting rod 53 and the second connecting rod 56 on both sides of the rotating shaft 55 are symmetrically arranged, which can make the center of gravity of the balancing device 5 located at the overlapping position of the cross formed by the first connecting rod 53, the second connecting rod 56 and the rotating shaft 55 and at the center position of the rotating shaft 55, preventing the rotating shaft 55 from being subjected to unbalanced forces and accelerating the wear of the rotating shaft 55. The counterweight 57 is located at the end of the second connecting rod 56. The two ends of the second connecting rod 56 are respectively fixedly connected to the counterweight 57 and the rotating shaft 55. The counterweight 57 is used to balance the gravity of the tray 52, the tray support 51 and the first connecting rod 53 on the other side of the rotating shaft 55.
[0021] See Figures 1 to 3, Further, the lower part of the counterweight 57 of the present utility model is respectively connected to the force-measuring component of the force measurer 6. The force measurer 6 is fixed on the fixing frame 7, and the fixing frame 7 is fixed on the drying box 3. A force measurer 6 is arranged below the counterweight 57 of each balancing device 5. The force measurer 6 is used to measure the real-time weight of the food placed on the tray 52. When there is no food placed on the tray 52, the overall balancing device 5 is balanced and the value of the force measurer 6 is zero. When food is placed on the tray 52, the tray 52 has a downward trend due to the gravity of the food. At this time, the counterweight 57 connected to the force measurer 6 has an upward trend. However, due to the setting of the force measurer 6, the upward trend of the counterweight 57 is stopped by the pulling force provided by the force measurer 6, and the force measurer 6 shows the weight of the food. The overall balancing device 5 remains stationary. The fixing frame 7 is fixed on the drying box 3 to fix the force measurer 6 and prevent the movement of the force measurer 6. When the tray 52 is removed, the mass on one side of the counterweight 57 is larger. After the counterweight 57 slightly descends, it is supported by the force measurer 6 and the fixing frame 7, preventing the balancing device 5 from rotating at too large an angle, which may make it difficult to place the tray 52 or cause interference with other parts of the dryer. The drying box 3 has the function of blocking temperature. Placing the force gauge 6 outside the drying box 3 can avoid damage to the internal components of the force gauge 6 caused by the high temperature inside the drying box 3.
[0022] See Figures 1 to 3 , Further, an air outlet 32 with a fan is arranged at the top of the drying box 3 of the present utility model. Several windows are arranged on the front of the drying box 3. A rotatable heat-insulating window 2 is arranged on the window. The heat-insulating window 2 is rotatably installed on the drying box 3 through a rotating shaft 22. Several alarms 31 are arranged on the side of the drying box 3. A heating box 1 is fixed at the bottom of the drying box 3. The heating box 1 is provided with a control panel 11. Arranging an air outlet 32 with a fan at the top of the drying box 3 can discharge the water vapor generated by drying the food out of the drying box 3, preventing the water vapor from gathering at the top of the drying box 3 and affecting the drying effect. Arranging multiple windows can reduce the communication area between the inside and the outside of the drying box 3 when taking and placing the tray 52, reduce heat loss, and lower energy consumption. The alarm 31 is used to remind the worker that the food in the tray 52 has reached the predetermined drying degree. The worker can set the predetermined drying degree by adjusting the drying ratio (drying ratio = weight of the dried food / weight of the food before drying).
[0023] See Figures 1 to 3, Further, there is a certain distance between the top of the heating box 1 of the present utility model and the balancing device 5, a certain distance is set between the balancing devices 5 pairwise, and a certain distance is set between the balancing device 5 and the top of the drying box 3. The distance C between the top of the heating box and the balancing device can prevent interference between the balancing device 5 and the top of the heating box 1. The distance B between the balancing devices pairwise is used to place food, prevent interference between the two balancing devices 5, and leave enough space to place the force measuring device 6. The distance A between the balancing device and the top of the drying box is used to place food and prevent interference between the balancing device 5 and the top of the drying box 3. The number of windows is equal to the number of balancing devices 5 and their positions correspond to each other. When it is necessary to take out or place the tray 52 of a certain balancing device 5, only the corresponding window needs to be opened. The heat preservation window 2 is provided with a heat insulation handle 21. The setting of the heat insulation handle 21 prevents the worker from being scalded due to overheating of the hand when opening and closing the heat preservation window 2. The number of alarms 31 is equal to the number of windows, and the positions of the alarms 31 correspond to the positions of the windows one by one. When the food in the tray 52 reaches the predetermined drying degree, the corresponding alarm 31 gives an alarm, and the worker opens the window corresponding to the alarm 31 that gives an alarm and takes out and replaces the tray 52. The dust-proof cover 4 is fixed on the fixing frame 7. The dust-proof cover 4 prevents components such as the force measuring device 6 outside the drying box 3 from accumulating dust and affecting the measurement accuracy of the force measuring device 6.
[0024] Working principle: The same type of food with equal size needs to be placed in a single tray 52. For example, in the embodiment, five trays 52 can respectively place five kinds of foods with different sizes or different drying degrees required. When the food dryer is not running, the foods are respectively placed into the trays 52, all the heat preservation windows 2 are closed, the drying temperature and the drying ratio of each tray 52 are set, and the food dryer runs. After the heat preservation window 2 is closed, the force measuring device 6 will measure and record the initial mass of the food in the tray 52 (that is, the mass of the food in the tray 52 before drying). Along with the operation of the dryer, the real-time mass of the food in the tray 52 decreases, and the value of the force measuring device 6 correspondingly decreases. When the real-time mass of the food in the tray 52 decreases to the mass of the dried food, the value of the force measuring device 6 is equal to the mass of the dried food that triggers the alarm (the worker sets the drying ratio of the food in each tray 52, so the mass of the dried food that triggers the alarm = the initial mass of the food in the tray 52 measured by the force measuring device 6 × the drying ratio), triggering the alarm. The worker opens the heat preservation window 2 corresponding to the alarm 31 that gives an alarm and takes out the tray 52. At this time, the value of the force measuring device 6 returns to zero and the alarm is turned off. When the tray 52 is put in again and the heat preservation window 2 is closed, the recorded initial mass value of the food by the force measuring device 6 is updated. When the drying ratios of the foods in the two trays 52 before and after are the same, no adjustment is required. When the drying ratios of the two trays 52 before and after are different, only the corresponding drying ratio of the food in the replaced tray 52 needs to be adjusted using the control panel 11.
[0025] In summary, the present utility model provides a food dryer, which includes a number of balancing devices. The balancing device includes a tray, a tray support, a first connecting rod, a rotating shaft, a second connecting rod, a rolling bearing, and a counterweight. The setting of the balancing device can avoid the influence of the self-weight of the dryer accessories on the calculation of the drying effect. A positioning pin is provided at the bottom of the tray, and a positioning hole is provided on the tray support. The tray is placed on the tray support. The setting of the positioning pin at the bottom of the tray and the positioning hole on the tray support can enable the tray to be placed at a specified position on the tray support, avoiding the change of the tray placement position from affecting the center of gravity of the balancing device. The tray support is fixed on the first connecting rod, and the first connecting rod is fixed on the cylindrical side surface of the rotating shaft. Rolling bearings are respectively provided at both ends of the rotating shaft, and the rolling bearings are fixed on the drying box. The second connecting rod is fixed on the rotating shaft and is symmetrical to the first connecting rod with respect to the rotating shaft. The counterweight is fixed on the second connecting rod. The center of gravity of the balancing device is located on the rotating shaft. The first connecting rod serves to connect the tray support and the rotating shaft. Rolling bearings fixed on the drying box are provided at both ends of the rotating shaft, enabling the rotating shaft to rotate by a certain angle. The second connecting rod symmetrical to the first connecting rod serves to connect the rotating shaft and the counterweight. The counterweight and the second connecting rod serve to balance the first connecting rod, the tray support, and the tray, adjusting the center of gravity of the balancing device to the rotating shaft. A force measuring device is respectively connected below the counterweight. The force measuring device provided below the counterweight of each balancing device can monitor the real-time weight of the food on each tray. The force measuring device is fixed on a fixing frame, and the fixing frame is fixed on the drying box. The setting of the fixing frame serves to fix the force measuring device, preventing the force measuring device from moving. An air outlet with a fan is provided at the top of the drying box. The air outlet with a fan can discharge the rising moist air after drying to the outside of the dryer, avoiding the accumulation of moist air from affecting the drying effect. A number of windows are provided on the front of the drying box, and a rotatable heat preservation window is provided on the window. The heat preservation window is rotatably installed on the drying box through a rotating shaft. The setting of the window enables the tray at the corresponding position of the window to be taken and placed separately, avoiding the excessive dissipation of the internal temperature of the dryer due to the setting of a large window. A number of alarms are provided on the side of the drying box. A heating box is fixed at the bottom of the drying box, and a control panel is provided on the heating box. The alarm is triggered to give an alarm reminder when the food in the tray reaches the specified drying degree. The heating box is responsible for providing the heat required for drying, and the control panel is responsible for regulating and setting the heating temperature of the heating box and the drying degree of the food on a single tray.
