Description

Technical Field

[0001] The utility model relates to the technical field of food preservation, in particular to a wasp pupae storage and preservation device. Background Art

[0002] Wasp pupae are increasingly favored by the market as a nutritious food that is high in protein, low in fat, and rich in various amino acids and trace elements. However, since wasp pupae contain high moisture and easily oxidizable ingredients, they are easily affected by the external environment during storage and become corrupt and deteriorate, which limits their supply and sales during the non-collection season.

[0003] For example, a storage device for edible silkworm pupae (Announcement No.: CN207023094U) includes a cabinet, a storage chamber, a refrigeration chamber, a sealing cover, a first limiting groove, a feeding port, a second limiting groove, a feeding pipe, a storage basket, a lifting handle, a plastic film, a fixing plate, a soft rope, a supporting block, a vibration motor, a refrigeration mechanism, a sound-absorbing cotton layer, a rubber seat, a sealing push plate, a push seat, a limiting plate and a magnet. The utility model storage device is provided with a feeding port on a traditional sealing cover. When a user needs to add silkworm pupae to the freezer, he only needs to open the feeding port, and the silkworm pupae can fall into the storage basket along the feeding pipe without having to completely open the cover; the plastic film can separate the silkworm pupae from the storage basket, thereby preventing the silkworm pupae from falling and soiling the storage basket. When taking the silkworm pupae, the user can directly remove the plastic film; the vibration motor can drive the storage basket to vibrate, thereby flattening the poured silkworm pupae to prevent the silkworm pupae from piling up and affecting the freezing effect.

[0004] However, the device still has the following defects:

[0005] When the device is in use, the main preservation method is low-temperature storage. During the storage process, oxygen is one of the main factors leading to the corruption and nutrient loss of bee pupae. The device lacks an effective gas replacement mechanism and cannot reduce the oxygen content in the cabinet in time, thus limiting the preservation effect. Therefore, we need to propose a wasp pupae storage and preservation device. Utility Model Content

[0006] The utility model aims to provide a wasp pupae storage and preservation device, aiming to solve the problem in the prior art that there is a lack of effective gas replacement mechanism and the oxygen content in the cabinet cannot be reduced in time, thus limiting the preservation effect.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A storage and preservation device for wasp pupae includes a storage cabinet. One side wall of the storage cabinet is fixedly connected and communicated with a nitrogen filling pipe. One side wall of the storage cabinet away from the nitrogen filling pipe is fixedly connected and communicated with an oxygen discharge pipe. The position of the nitrogen filling pipe is higher than that of the oxygen discharge pipe. The top of the storage cabinet is hinged with a sealing cabinet door through a hinge. Two groups of gas detectors are symmetrically and fixedly installed on the inner top of the storage cabinet. C-shaped support frames are respectively fixedly installed on the two inner side walls of the storage cabinet. A storage box is installed between the two C-shaped support frames.

[0009] Preferably, a through groove is opened at the top of the sealing cabinet door, and a guide pipe is fixedly connected to the bottom of the sealing cabinet door at the position of the through groove.

[0010] Preferably, a sliding groove is opened on the inner wall of the through groove. One end of the sliding groove penetrates through the sealing cabinet door, and a sealing sliding plate is slidably connected inside the sliding groove.

[0011] Preferably, a sealing block is fixedly connected to one side wall of the sealing sliding plate, and one side of the sealing block abuts against one side of the sealing cabinet door.

[0012] Preferably, a locking assembly for locking the sealing sliding plate is arranged at the top of the sealing cabinet door. The locking assembly includes two groups of sleeves. Both groups of sleeves are fixedly installed at the top of the sealing cabinet door. Plug rods are slidably inserted inside both groups of sleeves. The bottom ends of both groups of plug rods penetrate through the sealing cabinet door and are inserted into the inside of the sealing sliding plate, and the top ends of both groups of plug rods are fixedly connected with a pulling plate.

[0013] Preferably, it further includes two groups of return springs. The top ends of both groups of return springs are fixedly connected to the bottom of the pulling plate. The bottom ends of both groups of return springs are respectively fixedly connected to the tops of the two groups of sleeves, and both groups of return springs are respectively sleeved on the outer walls of both groups of plug rods movably.

[0014] Preferably, two groups of fixing blocks are respectively fixedly connected to the two side walls of the storage cabinet. One side of both groups of fixing blocks is fixedly connected with a connecting rope.

[0015] Preferably, a control panel is fixedly installed on one side wall of the storage cabinet, and a refrigeration device body is installed at the inner bottom of the storage cabinet. The gas detector and the refrigeration device body are both electrically connected to the control panel through wires.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] The utility model reduces the oxygen content in the air inside the storage cabinet to slow down the oxidation and spoilage process of hornet pupae, thereby extending their preservation period. Specifically, nitrogen filling pipes and oxygen discharge pipes are respectively arranged on the two side walls of the storage cabinet. First, the nitrogen filling pipes are connected to the supply equipment of inert gas, and then nitrogen or other inert gas can be injected into the interior of the storage cabinet. Since the density of nitrogen is lower than that of oxygen, when nitrogen is slowly injected, the oxygen inside the storage cabinet will be slowly discharged, thereby reducing the oxygen content inside the storage cabinet. This process needs to last for a period of time. Through the set gas detector, the oxygen content inside the storage cabinet can be monitored in real time to ensure that the oxygen content inside the storage cabinet is below the set target value.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-4, the present utility model provides a technical solution: a storage and preservation device for wasp pupae, including a storage cabinet 1. A nitrogen filling pipe 2 is fixedly communicated with one side side wall of the storage cabinet 1, and an oxygen discharge pipe 3 is fixedly communicated with the side wall of the storage cabinet 1 far away from the nitrogen filling pipe 2. Since the density of nitrogen is smaller than that of oxygen, the position of the nitrogen filling pipe 2 needs to be higher than that of the oxygen discharge pipe 3. One end of the oxygen discharge pipe 3 is provided with a sealing plug.

[0025] The top of the storage cabinet 1 is hinged with a sealing cabinet door 4 through a hinge. Two groups of gas detectors 5 are symmetrically and fixedly installed on the inner top of the storage cabinet 1. C-shaped support frames 6 are respectively fixedly installed on the inner walls on both sides of the storage cabinet 1. A storage box 7 is installed between the two groups of C-shaped support frames 6.

[0026] A ventilation area is reserved between the periphery of the storage box 7 and the inner wall of the storage cabinet 1, and the ventilation area is communicated with the inner cavity of the C-shaped support frame, which is beneficial to gas circulation, so as to facilitate gas replacement operation. The present utility model can slow down the oxidation and corruption process of wasp pupae by reducing the oxygen content in the air in the storage cabinet 1, thereby prolonging its preservation period;

[0027] A through groove 8 is opened at the top of the sealing cabinet door 4. A guide pipe 9 is fixedly connected to the bottom of the sealing cabinet door 4 at the through groove 8. By opening the through groove 8 on the sealing cabinet door 4 and cooperating with the guide pipe 9, wasp pupae can be placed into the storage box 7 without opening the sealing cabinet door 4, which can avoid a large amount of cold air flowing out, causing energy waste, and can reduce the oxygen intake;

[0028] A sliding groove 10 is opened on the inner wall of the through groove 8. One end of the sliding groove 10 penetrates through the sealing cabinet door 4. A sealing sliding plate 11 is slidably connected inside the sliding groove 10. By setting the cooperation of the sliding groove 10 and the sealing sliding plate 11, when it is necessary to store wasp pupae, the sealing sliding plate 11 can be opened, so that it is not necessary to open the entire sealing cabinet door 4, thereby achieving the effect of reducing cold air leakage and oxygen intake;

[0029] A sealing block 12 is fixedly connected to one side side wall of the sealing sliding plate 11. One side of the sealing block 12 abuts against one side of the sealing cabinet door 4. By setting the sealing block 12, it plays a role in increasing the airtightness between the sealing sliding plate 11 and the sealing cabinet door 4;

[0030] A locking assembly 13 for locking the sealing slide plate 11 is provided at the top of the sealed cabinet door 4. The locking assembly 13 includes two sets of sleeves 1301. The two sets of sleeves 1301 are fixedly installed on the top of the sealed cabinet door 4. Pins 1302 are slidably inserted inside the two sets of sleeves 1301. The bottom ends of the two sets of pins 1302 penetrate the sealed cabinet door 4 and are inserted into the inside of the sealing slide plate 11. The top ends of the two sets of pins 1302 are fixedly connected with a pull plate 1303. The locking assembly 13 also includes two sets of reset springs 14. The top ends of the two sets of reset springs 14 are fixedly connected to the bottom of the pull plate 1303. The bottom ends of the two sets of reset springs 14 are fixedly connected to the tops of the two sets of sleeves 1301, and the two sets of reset springs 14 are movably sleeved on the outer walls of the two sets of pins 1302.

[0031] Specifically, when the sealing slide plate 11 needs to be opened, it is only necessary to pull the pull plate 1303 to separate the two sets of pin rods 1302 from the sealing slide plate 11, and then the sealing slide plate 11 can be slid open. A handle (not shown in the figure) can be provided on the sealing slide plate 11 to facilitate opening.

[0032] Two sets of fixing blocks 15 are fixedly connected to the side walls of the storage cabinet 1, and one side of the two sets of fixing blocks 15 is fixedly connected to a connecting rope 16. The bottom ends of the two sets of connecting ropes 16 are fixedly connected to magnetic pieces 17. The magnetic piece 17 is adsorbed and connected to the top of the storage box 7. The top of the storage box 7 is provided with an opposite sex piece that is mutually adsorbed with the magnetic piece 17. By setting the magnetic piece 17, the fixing block 15 and the connecting rope 16 for coordinated use, when a fresh-keeping bag (the fresh-keeping bag is used to store wasp pupae) is provided inside the storage box 7, the edge of the bag opening of the fresh-keeping bag can be pressed and positioned with the top of the storage box 7 by the magnetic piece 17, so that the bag opening of the fresh-keeping bag can always be kept in an open state, which is convenient for the subsequent addition of wasp pupae that need to be stored;

[0033] A control panel 18 is fixedly installed on one side wall of the storage cabinet 1, and a refrigeration device body 19 is installed on the inner bottom of the storage cabinet 1. The gas detector 5 and the refrigeration device body 19 are electrically connected to the control panel 18 through wires. By setting up the gas detector 5, the oxygen content inside the storage cabinet 1 is monitored in real time. The circuit connection is an existing mature technology and will not be repeated here. By setting up the refrigeration device body 19, the interior of the storage box 7 can be refrigerated, thereby reducing the temperature inside the storage box 7, and the oxygen content inside the storage cabinet is reduced, which is beneficial to further extend the shelf life of the hornet pupae.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
