[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example

[0034] like Figures 1 to 6 As shown, a persimmon ripening device for food processing includes a ripening box 1, an ethylene generating mechanism 2 and an oxygen generating mechanism 3. The ethylene generating mechanism 2 and the oxygen generating mechanism 3 are both arranged on the ripening box 1 and are both connected to the ripening box 1. A plurality of placement plates 11 for placing persimmons are slidably arranged at intervals in the ripening box 1. The ethylene generating mechanism 2 includes a hydraulic cavity 21, an air intake pipe 22, an air suction pipe 23 and a gas control component 24. The hydraulic cavity 21 is arranged on the ripening box 1 through a support frame 400. One end of the air intake pipe 22 and the air suction pipe 23 are connected to the lower end of the hydraulic cavity 21, and the other end is connected to the ripening box 1. A plurality of air intake holes 221 are arranged on the air intake pipe 22, and an air suction hole 231 is opened on the air suction pipe 23. The gas control component 24 is arranged in the hydraulic cavity 21 and is slidably arranged in the air intake pipe 22 and the air suction pipe 23, respectively, to open or close the air intake hole 221 and the air suction hole 231.

[0035] The sliding placement plate 11 can adopt a drawer structure style with a sealing strip and a slide rail to ensure the air tightness of the ripening box 1 during the ripening operation; in addition, in order to observe the ripening status of persimmons in the ripening box 1, a lighting device such as an LED lamp can be arranged in the ripening box 1, and an observation window (not shown in the figure) can be arranged on the outer wall of the ripening box 1 in the sliding direction of the placement plate 11. The observation window is made of transparent materials such as acrylic, which is convenient for observing the ripening status of persimmons during ripening without opening the door and does not affect the gas stability in the box.

[0036] The present invention utilizes the gas control component 24 of the ethylene generating mechanism 2 to control the ethylene content in the ripening box 1, thereby preventing a part of the fruit from ripening too quickly or too slowly and affecting the overall fruit ripening effect; at the same time, the oxygen generating mechanism 3 is provided to control the oxygen content in the ripening box, stimulate the fruit to breathe and improve its breathing efficiency to achieve a consistent degree of ripening of the fruit, thereby increasing its moisture content and sugar content, and improving the taste of the fruit, so as to achieve the purpose of ripening and improve work efficiency.

[0037] In this embodiment, please refer to Figure 3 The gas control assembly 24 includes a hydraulic cylinder 241, a connecting seat 242, an intake control column 243 and an intake control column 244. The hydraulic cylinder 241 is arranged in the hydraulic cavity 21, and its telescopic end is arranged downward and connected to the connecting seat 242. One end of the intake control column 243 and the intake control column 244 are connected to the lower end of the connecting seat 242, and the other end is slidably arranged in the intake pipe 22 and the intake pipe 23 respectively; during specific operation, the hydraulic cylinder 241 is used to drive the connecting seat 242 to slide upward, thereby driving the intake control column 243 and the intake control column 244 in the intake pipe 22 and the intake pipe 23 respectively. During the sliding process of the intake control column 243, one or more intake holes 221 can be opened to increase the input rate of ethylene in the ripening box 1; and the intake control column 244 can close the intake hole 231 at this time to avoid leakage of ethylene in the ripening box 1. The two are carried out simultaneously to optimize the structural setting and improve the intelligent operation.

[0038] Specifically, the air intake control column 244 includes a connecting portion 2441 and a closing portion 2442. The diameters of the air intake control column 243 and the closing portion 2442 are respectively the same as the inner diameters of the air intake pipe 22 and the air intake pipe 23, and the diameter of the connecting portion 2441 is smaller than the inner diameter of the air intake pipe 23. During the upward sliding process of the air intake control column 244, the air intake hole 231 can be closed by the closing portion 2442. A plurality of air guide holes 4 are provided on the closing portion 2442. The air guide holes 4 serve to connect the ripening box 1 and the air intake hole 231, that is, when it is necessary to reduce the ethylene content in the ripening box 1, the hydraulic cylinder 241 is used to drive the connecting seat 242 to slide downward. At this time, the air intake control column 243 closes the air intake hole 221. At this time, the closing portion 2442 slides away from the air intake hole 231, so that the air guide hole 4 is connected to the air intake hole 231, and then the excess ethylene is absorbed and removed by an external air intake source.

[0039] In the present embodiment, an air intake cavity 5 is provided on the air intake pipe 22 at the side of the air intake hole 221, and the air intake cavity 5 is connected to an external air intake source through a conduit. An air intake cavity 6 is provided on the air intake pipe 23 at the side of the air intake hole 231, and the air intake cavity 6 is connected to an external air intake source through a conduit. The arrangement of the air intake cavity 5 and the air intake cavity 6 facilitates improving the air intake efficiency and the air intake efficiency of the device.

[0040] In addition, please refer to Figure 2 A plurality of air intake branch pipes 100 and an air intake branch pipe 200 are respectively connected between the air intake pipe 22, the air intake pipe 23 and the ripening box 1, and a nozzle 7 is provided at the end of the air intake branch pipe 100; the nozzle 7 improves the ethylene transportation efficiency and can facilitate the uniform distribution of ethylene in the ripening box 1, avoiding dead corners or corners with low ethylene content, assimilating the ripening rate and effect of the entire fruit in the ripening box 1, and avoiding that some of the fruits mature too quickly or too slowly and affect the overall fruit ripening effect.

[0041] For details, please refer to Figure 4The nozzle 7 includes a connecting piece 71, a shell 72, an end piece 73, a pressure spring 74 and a plate 75. The connecting piece 71 is arranged between the shell 72 and the intake branch pipe 100 and is threadedly connected to the two. A limiting ring 721 is arranged in the shell 72. The end piece 73 is provided with a boss 731 pressed against the limiting ring 721. The outer end of the end piece 73 extends to the outside of the shell 72, and a plurality of air outlet holes 732 are arranged in a circular array on the outer wall. The pressure spring 74 is sleeved on the end piece 73, and one end of the pressure spring is connected to the boss 731, and the other end is connected to the plate 75. 75 is connected, and the abutment plate 75 abuts on the connecting piece 71; during specific operation, ethylene gas enters the air inlet branch pipe 100 and the connecting piece 71 from the air inlet pipe 22, and finally the gas pushes the abutment plate 75 and is pumped into the end piece 73. The end piece 73 increases the pressure due to the gradual accumulation of gas, and the accumulated gas is pumped into the ripening box 1 through the air outlet 732; and the multiple air outlet holes 732 arranged in a ring shape can distribute the gas to various ranges of the ripening box 1 in a large atmosphere, thereby improving the overall fruit ripening rate and effect, and maintaining the rate consistency of the fruit ripening operation.

[0042] In this embodiment, please refer to Figure 5 and Figure 6 , a plurality of accommodating cavities 111 are provided on the placement plate 11, and a placement groove 112 is concavely provided in the accommodating cavity 111, and a substrate 113 for placing persimmons is embedded in the placement groove 112, and a weight sensor (not shown in the figure) is provided on the substrate 113; in specific operation, in order to determine whether the fruit is ripe, the weight sensor can be used to measure the weight change of the fruit; that is, during the ripening process of the persimmon, its moisture content, sugar content, pulp density, etc. all change, which ultimately affects and causes its weight to change. In the raw persimmon stage, persimmons contain more starch and less sugar, the flesh is harder, the moisture content is relatively low, and the weight is smaller. As they mature, the starch in the persimmons gradually converts into sugar, the flesh begins to soften, and the moisture content increases. At this time, the weight of the persimmon increases, and finally the ripeness of the fruit can be determined by the weight change ratio.

[0043] Specifically, an elastic pad 8 is provided on the placement groove 112; the elastic pad 8 can improve the accuracy of fruit weight measurement; the oxygen generating mechanism 3 has the same structure as the ethylene generating mechanism 2; when measuring the oxygen content inside the ripening box 1, the above-mentioned ethylene content measurement steps are adopted, and maintaining the oxygen content in the ripening box 1 can improve the ripening efficiency, as well as the taste of the fruit.

[0044] In addition, the present invention also includes an electrical control system, which includes a control box 300, an ethylene control sensor, an oxygen control sensor, a temperature sensor, a humidity sensor and an alarm (all shown in the figure), etc. The ethylene control sensor, the oxygen control sensor, the temperature sensor, the humidity sensor and the alarm, as well as the weight sensor and the hydraulic cylinder 241 are all electrically connected to the control box 300, and their connection relationship is a conventional technical means, which will not be repeated here.

[0045] The ethylene control sensor and the oxygen control sensor are used to monitor the ethylene and oxygen contents in the ripening box 1, respectively, so as to facilitate controlling the ethylene generating mechanism 2 and the oxygen generating mechanism 3 to be at an ideal level in the ripening box 1;

[0046] The temperature sensor and humidity sensor are used to monitor the temperature and humidity in the ripening box 1, so that the fruit is in a relatively ideal state for ripening operation; when the temperature and humidity in the ripening box 1 do not meet the settings, an alarm is used to remind, thereby adjusting the relevant indexes in the ripening box 1. The temperature and humidity adjustment belongs to conventional technical means and will not be described in detail here;

[0047] The weight change ratio of the persimmons is set in the electrical control system, and an alarm is used to warn when the weight sensor measures that the weight change has been reached.

[0048] The present invention utilizes the gas control component 24 of the ethylene generating mechanism 2 to control the ethylene content in the ripening box 1, thereby preventing a part of the fruits from ripening too quickly or too slowly and affecting the overall fruit ripening effect; at the same time, the oxygen generating mechanism 3 is provided to control the oxygen content in the ripening box 1, stimulate the respiration of the fruits and improve their respiration efficiency to achieve a consistent degree of ripening of the fruits, thereby increasing their moisture content and sugar content, and improving the taste of the fruits, thereby achieving the purpose of ripening and improving work efficiency.

[0049] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
