[0046] Ethrel is a kind of chemical substance commonly used in fruit and vegetable ripening technology field, generally speaking, low temperature environment can slow down the decomposition rate of ethrel, and affect the movement of ethrel in fruit, so ethrel needs to be in high temperature condition (generally above 20 DEG C) to play a better ripening effect. In the related art, ethrel is combined with high temperature to ripen fruit on the market at present, however, high temperature environment can accelerate the respiration and transpiration of fruit, speed up the consumption of nutrients and water loss of fruit, affect the preservation of fruit, and the continuous high temperature is easy to cause burn on the skin and pulp of fruit, affect the taste and quality of fruit.
[0047] To solve the above problems, the application provides a fruit and vegetable storage box.
[0048] Please refer to Figure 1 , the fruit and vegetable storage box 10 includes a box body 100 and a ripening device 200. The box body 100 is provided with a ripening space 110, and the ripening device 200 is arranged in the ripening space 110, and the ripening device 200 is configured to ripen the fruit and vegetable in the ripening space 110 by physical method. Among them, the physical ripening method can include light ripening, vibration ripening and the like.
[0049] The ripening device 200 uses physical method to ripen the fruit and vegetable, compared with the ethrel ripening (chemical method) in the related art, which does not need the limitation of high temperature condition, so the ripening space 110 can be set in low temperature environment to ripen the fruit and vegetable. In the embodiment of the application, the temperature of the ripening space 110 is the first temperature, the first temperature is greater than or equal to 12 DEG C, and less than or equal to 15 DEG C.
[0050] It can be understood that the environment of 12-15℃ is a low temperature environment, and placing the ripening space 110 at this temperature can reduce the respiration and transpiration of fruits, slow down the loss of nutrients and water in the fruits, and is beneficial to the preservation of the fruits. Moreover, the temperature of 12-15℃ is not too low, and is suitable for the preservation of most fruits and vegetables, especially for tropical fruits. Please refer to Figure 2 , 12-15℃ is the best storage temperature for most tropical fruits, and the refrigeration temperature of the conventional refrigerator in the related art is generally 0-8℃, which is not suitable for the preservation and storage of tropical fruits, and cold damage is likely to occur. The ripening space of the embodiment of the present application is set at 12-15℃, which can avoid the cold damage problem of tropical fruits.
[0051] Please refer to Figures 3 to 5 , the applicant of the utility model carries out ripening experiments on bananas, mangoes and avocados in environments of 4℃ (too low temperature), 12℃ (low temperature) and 25℃ (high temperature) respectively, and obtains Figures 3 to 5 the appearance change diagram of each group of fruits in the ripening process. As shown in the figure, after ripening in the high temperature environment of 25℃, although the bananas, mangoes and avocados all show high maturity, the banana skin appears large dark patches (over-ripe, easy to turn black and rot inside), the mango skin appears obvious anthracnose, and the avocado skin looks fine, but from the slices it can be seen that the internal flesh of the avocado has local rot. After ripening in the too low temperature environment of 4℃, the banana, mango and avocado skins still have a large area of green color, that is, the maturity of the three in the environment of 4℃ is not high, and the banana and mango skins appear local blackening, and obvious cold damage phenomenon occurs. After ripening in the environment of 12℃, the green areas of the banana, mango and avocado skins are mostly faded, and have good maturity, and the skins of the three fruits are clean and have no obvious black spots and anthracnose. From the avocado slices, it can be seen that the flesh is good and has no corruption. Therefore, according to the above experimental results, it is verified that using 12℃ low temperature to store and ripen fruits can not only make the fruits have good maturity, but also is beneficial to the preservation of the fruits, can ensure the quality of the fruits, and prevent the fruits from being damaged by too low temperature or rotting or producing anthracnose due to high temperature.
[0052] In the embodiment of the utility model, through setting ripening device 200 in ripening space 110, ripening device 200 adopts physical way to ripen fruit, compared with ripening by using ethephon in the related art, without the restriction of high temperature condition, so by setting the temperature of ripening space 110 as the first temperature, the first temperature is greater than or equal to 12 DEG C and less than or equal to 15 DEG C, make ripening space 110 in the lower temperature environment, low temperature can slow down the nutrition consumption and water loss of fruit and vegetable, is favorable to maintaining the freshness of fruit and vegetable, and, the first temperature is set between 12 DEG C-15 DEG C, the temperature is not too low, can avoid the cold damage of fruit and vegetable.The fruit and vegetable storage box 10 of the utility model adopts low temperature to combine physical way to ripen fruit and vegetable, not only can improve the maturity of fruit and vegetable, simultaneously can guarantee the quality of fruit and vegetable.
[0053] Light is an important environmental factor affecting plant growth and development, and a certain amount of light can induce chlorophyll decomposition, increase related pigment synthesis, induce ethylene peak appearance, etc., and has a promoting effect on fruit and vegetable ripening. In some embodiments, the ripening device 200 includes a light source 210, and the light source 210 is used to emit light of a predetermined wavelength to the ripening space 110 to promote the ripening of the fruit and vegetable in the ripening space 110 under light.
[0054] It should be noted that the light emitted by the light source 210 for light ripening of the fruit can avoid the problem of uneven maturity or easy over-ripening of the fruit and vegetable caused by improper control of the amount of ethylene added compared to traditional ripening with ethylene.
[0055] Please continue to refer to Figures 3 to 5 The applicant of the utility model also sets up a control group to ripen bananas, mangoes and avocados in a 12 DEG C light environment. As can be seen from the figure, the skin color of the above-mentioned fruits after light ripening is darker, that is, the maturity of the above-mentioned fruits under light is higher than that without light, especially mangoes, after 9 days of ripening under light, the skin of the mangoes is almost completely yellow, while after 9 days of ripening in the dark, there is still a small part of the skin of the mangoes that is green. Obviously, light can accelerate the ripening speed of the fruit and make it easier to ripen. Therefore, the present embodiment ripens by low temperature combined with light, which not only effectively improves the maturity of the fruit and vegetable, but also can guarantee the quality of the fruit and vegetable.
[0056] Red light is important to the development of photosynthetic apparatus of plants, and red light can improve the net photosynthetic rate to promote the growth and development of plants; blue light can promote the development of chloroplasts, the opening of stomata and the growth of branches of plants. In order to verify the ripening effect of red light and blue light on fruits and vegetables, the applicant of the utility model sets three groups of fruits (mainly small mangoes and avocados) with the same maturity under the same temperature for experiment, one group of fruits matures naturally without light irradiation, and the other two groups of fruits are irradiated by blue light and red light respectively. For convenience of description, the fruits that mature naturally are defined as the first group, the fruits irradiated by blue light are defined as the second group, and the fruits irradiated by red light are defined as the third group. After two days of ripening, the maturity of fruits is comprehensively judged by the hardness and sweetness indexes of fruits, and it is detected that the maturity of the first group is less than that of the second group, and the maturity of the second group is less than that of the third group. Therefore, according to the experimental results, it is further verified that the ripening effect of light irradiation on fruits and vegetables is better than the natural ripening effect of fruits and vegetables without light, and it is known that the ripening effect of red light on fruits and vegetables is better than that of blue light on fruits and vegetables.
[0057] In order to improve the ripening efficiency of fruits and vegetables, in an embodiment, the light with the preset wavelength is red light, and the light source 210 is configured to emit red light to ripen the fruits and vegetables in the second storage space.
[0058] The ripening space 110 is provided with a support surface for carrying fruits and vegetables. In order to make the light emitted by the light source 210 irradiate all the fruits and vegetables as much as possible, in some embodiments, the light source 210 is arranged at the top of the ripening space 110, and the light source 210 is arranged opposite to and spaced from the support surface, so that the light source 210 emits light from top to bottom, and the light sufficiently irradiates the fruits and vegetables carried on the support surface, so that the light irradiation on the surface of the fruits and vegetables is uniform, and the non-uniform ripening of the fruits and vegetables can be avoided.
[0059] In order to understand the influence of different light intensities on the ripening of fruits and vegetables, the applicant of the utility model sets three experimental groups and one control group, the three experimental groups are respectively irradiated by low-intensity, medium-intensity and high-intensity red light to ripen avocados, and the control group matures naturally without light. The following table is the light intensity value of each group. It should be noted that the average light intensity in the following table is the average light intensity of each position on the support surface, and the center light intensity is the light intensity of the middle position on the support surface.
[0060] Light intensity Average light intensity on the support surface (pmol / m2 / s) Central light intensity on the support surface (pmol / m2 / s) Low 10 15 Medium 25 40 High 45 75
[0061] Please refer to Figure 6 From Figure 6 (A), it can be understood that under the same temperature and the same ripening time, the hardness change of avocados is greater with the increase of the light intensity of red light, and the higher the light intensity, the lower the hardness of avocados after ripening; from Figure 6The sugar content change graph of (B) can understand that, under the same temperature and the same ripening time, the sugar content change of the avocado is greater with the increase of the illumination intensity of the red light, and the higher the illumination intensity, the higher the sugar content of the avocado. The hardness change and the sugar content change are the main basis for judging the maturity of fruits and vegetables, so the higher the illumination intensity of the light source 210, the higher the maturity of the fruits and vegetables after ripening, that is, the high-intensity light environment has a better ripening effect on fruits and vegetables.
[0062] Therefore, in order to improve the ripening efficiency of fruits and vegetables, high-intensity light can be used to ripen fruits and vegetables. In an embodiment, the light source 210221 is configured to enable the average illumination intensity of the irradiation to the support surface to be greater than or equal to 45 umol / m2 / s, and the central illumination intensity of the irradiation to the support surface to be greater than or equal to 75 umol / m2 / s.
[0063] In some embodiments, the box 100 is also provided with a fresh-keeping space 120. The fresh-keeping space 120 is a variable-temperature space, and the temperature of the fresh-keeping space 120 can be switched between a second temperature and a first temperature. The second temperature is less than the first temperature, and the second temperature can be between 2°C and 8°C.
[0064] The box 100 is also provided with the fresh-keeping space 120, and fruits with higher maturity or fruits ripened in the ripening space 110 can be stored in the fresh-keeping space 120. By setting the fresh-keeping space 120 as a variable-temperature space, the fresh-keeping storage needs of different fruits can be met. For example, when the fruits stored in the fresh-keeping space 120 are non-tropical fruits, the fresh-keeping space 120 can be set at the second temperature, and the temperature is relatively low, which is beneficial to maintaining the freshness of the non-tropical fruits; when the fruits stored in the fresh-keeping space 120 are tropical fruits, the fresh-keeping space 120 is set at the second temperature, and the temperature of the fresh-keeping space 120 at this time is the best storage temperature for most tropical fruits, which can prevent the occurrence of cold damage phenomenon of the tropical fruits and ensure the quality of the tropical fruits.
[0065] Specifically, the fruit and vegetable storage box 10 can be provided with a heating mechanism and / or a refrigeration mechanism to adjust the temperature of the ripening space 110 and the fresh-keeping space 120.
[0066] In some embodiments, please refer to Figure 1 , Figure 7 and Figure 8The fresh-keeping space 120 and the ripening space 110 are arranged along a height direction of the box body 100, and the fresh-keeping space 120 is located at a bottom of the ripening space 110. The fruit and vegetable storage box 10 further comprises a support plate assembly 300, the support plate assembly 300 comprising a fixed plate 310 and a movable plate 320, the fixed plate 310 being connected with an inner wall of the box body 100 and arranged between the ripening space 110 and the fresh-keeping space 120, and the fixed plate 310 being provided with a through hole 311. The movable plate 320 is movably arranged on the fixed plate 310 and can be switched between a first position and a second position under the action of an external force.
[0067] When the movable plate 320 is located at the first position, the movable plate 320 covers the through hole 311, and the movable plate 320 is used for supporting fruits and vegetables in the ripening space 110. At this time, the movable plate 320 and the fixed plate 310 jointly separate the ripening space 110 and the fresh-keeping space 120. When the movable plate 320 is switched to the second position, the movable plate 320 exposes the through hole 311, and the fruits and vegetables in the ripening space 110 fall into the fresh-keeping space 120.
[0068] In an embodiment, the support plate assembly 300 further comprises a driving mechanism, the driving mechanism comprising a driving motor (not shown) and a rotating shaft 330 connected with the driving motor. As shown in Figure 9 the rotating shaft 330 is connected with the movable plate 320, and the driving motor is used for driving the rotating shaft 330 to rotate, so as to drive the movable plate 320 to rotate and switch between the first position and the second position.
[0069] In an embodiment, one end of the movable plate 320 is rotatably connected with the fixed plate 310, and the other end of the movable plate 320 is a free end. The movable plate 320 is flipped relative to the fixed plate 310 under the action of an external force. In the first position, the part of the movable plate 320 between the one end connected with the fixed plate 310 and the other end covers the through hole 311. That is, only one movable plate 320 is arranged in the embodiment, one end of the movable plate 320 is rotatably connected with the fixed plate 310, and the automatic falling of the fruits and vegetables is realized by the movement of the single movable plate 320. The structure is simple, the number of driving motors can be reduced, and the driving control program can be simplified.
[0070] In some embodiments, the fruit and vegetable storage box 10 further comprises a detection assembly 400, the detection assembly 400 being used for detecting the maturity of the fruits and vegetables in the ripening space 110, so that the user can take the fruits and vegetables reaching a certain maturity from the ripening space 110 for eating or transferring to the fresh-keeping space 120 for storage.
[0071] Please refer to Figure 1The detection assembly 400 can include a camera 410 and a near-infrared detector 420. During the ripening process of the fruit, the appearance of the surface of the fruit changes. As the fruit gradually ripens, the color of the surface of the fruit generally becomes darker. The camera 410 can take a picture of the fruit to obtain the color change of the skin of the fruit. During the ripening process of the fruit, the hardness and the sugar content of the fruit change. As the fruit gradually ripens, the hardness gradually becomes soft, and the sugar content increases. The near-infrared detector 420 can obtain the hardness and the sugar content change of the fruit, so that the maturity of the fruit can be comprehensively judged according to the appearance, the hardness and the sugar content of the fruit. It should be noted that the near-infrared detector 420 is a kind of known technology for detecting the hardness and the sugar content of the fruit by using near-infrared spectrum technology, and the detection principle is not described here.
[0072] In some embodiments, the driving mechanism is configured to drive the movable plate 320 to move to the second position when the detection assembly 400 detects that the fruits and vegetables in the ripening space 110 reach the preset maturity. It can be understood that the preset maturity is a comparative reference set by a person for checking the maturity of the fruits and vegetables, and the preset maturity can be set according to the specific requirements of the user.
[0073] Therefore, the action of the driving mechanism is associated with the detection of the detection assembly 400. When it is detected that the fruits and vegetables in the ripening space 110 reach the preset maturity, the driving mechanism drives the movable plate 320 to move from the first position to the second position, so that the ripe fruits in the ripening space 110 automatically fall into the preservation space 120, thereby realizing the automatic transfer of the ripe fruits, preventing the fruits from being over-ripe due to the lack of timely transfer, and affecting the eating taste and storage time of the fruits. In addition, since the transfer action does not need to be manually operated by a person, the use experience can be improved.
[0074] In some embodiments, the fruit and vegetable storage box 10 further includes a buffer mechanism 500 arranged in the preservation space 120. The buffer mechanism 500 is used to provide a buffering effect for the falling fruits and vegetables, so as to prevent the fruits and vegetables from being damaged when falling and affecting the storage time and taste of the fruits and vegetables. The buffer mechanism 500 can be a receiving plate with a spring installed at the bottom, or a flexible pad made of a flexible material such as sponge, and the embodiments of the present application do not limit this.
[0075] The utility model also provides a kind of refrigeration equipment, and refrigeration equipment includes temperature control device and uses the fruit and vegetable storage box 10 of any embodiment conception above, temperature control device includes refrigeration mechanism and / or heating mechanism, and refrigeration equipment is ripening space 110 at first temperature by temperature control device.
