Description

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0050] The present invention provides a low-temperature rapid thawing device, which comprises:

[0051] A thawing box 1 is provided with at least two thawing chambers 2 for accommodating thawing medium and frozen objects, each thawing chamber 2 is provided with a carrying mechanism 3 for loading frozen objects, and each carrying mechanism 3 is driven to move by a corresponding driving mechanism 4;

[0052] The internal circulation mechanism 5 is configured to allow the thawing medium to circulate between the thawing chambers 2;

[0053] The temperature regulation system includes a temperature detector and an external circulation mechanism 6. The temperature detector is arranged in at least one thawing chamber 2. The external circulation mechanism 6 is configured to discharge the thawing medium in the thawing chamber 2 to the outside and inject the external thawing medium into the thawing chamber 2 according to the temperature data detected by the temperature detector to adjust the temperature of the thawing medium in the thawing chamber 2.

[0054] The low-temperature rapid thawing device provided in this embodiment, when in use, places the frozen objects in the supporting mechanisms 3 in different thawing chambers 2 respectively, injects thawing medium into the thawing chambers 2, and then starts the internal circulation mechanism 5, the temperature adjustment system and the driving mechanism 4 in each thawing chamber 2 to thaw the frozen objects. During the thawing process, the internal circulation mechanism 5 can realize the internal circulation of the thawing medium between the thawing chambers 2, realize the flowing water thawing of the frozen objects, and improve the thawing efficiency of the frozen objects; the driving mechanism 4 can drive the supporting mechanism 3 to move in the thawing chamber 2, and then drive the frozen objects in the supporting mechanism 3 to move back and forth, so that the frozen objects are in contact with the thawing medium more evenly, accelerate the heat exchange between the thawing medium and the frozen objects, and improve the thawing efficiency; the external circulation mechanism 6 can be selectively opened according to the temperature of the thawing medium in the thawing chamber 2. When the temperature of the thawing medium is too low, the thawing medium in the thawing chamber 2 is discharged to the outside, and the external thawing medium is injected into the thawing chamber 2 until the temperature of the thawing medium in the thawing chamber 2 rises to the specified temperature range again. Such a cycle can make the thawing medium in the thawing chamber 2 always maintain within the specified low temperature range, ensure the low temperature environment of the frozen objects, realize the low temperature thawing of the frozen objects, keep the frozen objects fresh, and improve their quality after thawing.

[0055] The low-temperature rapid thawing device, through the combination of the driving mechanism 4, the internal circulation mechanism 5 and the temperature regulating system, can not only ensure the low-temperature environment of the frozen objects and realize the low-temperature thawing of the frozen objects, but also accelerate the heat exchange between the frozen objects and the thawing medium, thereby improving the thawing efficiency of the frozen objects; by arranging at least two thawing chambers 2 in the thawing box 1, the device can arrange different driving mechanisms 4 in different thawing chambers 2, and adopt different driving methods to drive the frozen objects of different categories and different packaging specifications to move, so as to realize the thawing of frozen objects of different categories and different packaging specifications separately in a targeted manner, and can quickly complete the low-temperature thawing of all categories under complex working conditions, and the overall versatility of the device is stronger.

[0056] It should be noted that the thawing medium in this embodiment can be tap water.

[0057] The low-temperature rapid thawing device provided by the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 This is a schematic diagram of the structure of a low-temperature rapid thawing device provided by at least one embodiment of the utility model. Figure 1 As shown, the low-temperature rapid thawing device includes a thawing box 1, an internal circulation mechanism 5 and a temperature adjustment system.

[0058] The thawing box 1 is a container for containing thawing medium and frozen food, and it can be of any suitable shape and structure. Figure 1 In the present embodiment, the thawing box 1 may be a rectangular box having a cavity inside and an opening on the top. Of course, the opening on the top of the thawing box 1 may also be closed by providing an openable lid.

[0059] In this embodiment, the inner cavity of the thawing chamber 2 is divided into at least two independent thawing chambers 2. For example, the number of thawing chambers 2 can be two, three, four or more, and each thawing chamber 2 is used to accommodate thawing medium and frozen objects. Figure 1 Each thawing chamber 2 is provided with a carrying mechanism 3 for loading frozen objects, and each carrying mechanism 3 is correspondingly provided with a driving mechanism 4 to drive the movement thereof. With such a configuration, frozen objects of different categories and packaging specifications can be placed in different thawing chambers 2, and different driving mechanisms 4 are provided corresponding to different thawing chambers 2. Different driving modes are used to drive frozen objects of different categories and packaging specifications to move, so that frozen objects of different categories and packaging specifications can be thawed separately in a targeted manner, and low-temperature thawing of all categories can be quickly completed under complex working conditions, and the overall versatility of the device is stronger.

[0060] In this embodiment, two thawing chambers 2 are provided in the thawing box 1. Figure 2 A partition wall 101 is disposed in the thawing box 1, and the partition wall 101 is vertically disposed in the thawing box 1, so as to divide the inner cavity of the thawing box 1 into a first thawing cavity 201 and a second thawing cavity 202 that are independent of each other. The first thawing cavity 201 and the second thawing cavity 202 are both rectangular cavities, and the volumes of the first thawing cavity 201 and the second thawing cavity 202 can be designed according to the quantity of frozen products of different categories and packaging specifications. For example, Figure 2 The embodiment in which the first thawing chamber 201 has a larger volume and the second thawing chamber 202 has a smaller volume is exemplified.

[0061] Correspondingly, in this embodiment, the supporting mechanism 3 arranged in the first thawing chamber 201 is the first supporting mechanism 301, and the driving mechanism 4 is the first driving mechanism 401; the supporting mechanism 3 arranged in the second thawing chamber 202 is the second supporting mechanism 302, and the driving mechanism 4 is the second driving mechanism 402.

[0062] In this embodiment, the first carrying mechanism 301 is mainly used to load bagged frozen food, boxed frozen food, etc. For details, see Figure 1 and Figure 3 The first bearing mechanism 301 includes a hollow mobile bracket, which is a rectangular body, and has a bearing space for bearing frozen objects inside. The length and width of the mobile bracket are smaller than the length and width of the first thawing chamber 201, so as to facilitate the linear movement of the mobile bracket in the first thawing chamber 201. In this way, the hollow mobile bracket can ensure that the frozen objects placed in the mobile bracket are in full contact with the thawing medium, and the mobile bracket is large, and can simultaneously accommodate frozen objects of different categories and different packaging specifications, so as to achieve synchronous thawing of various frozen objects.

[0063] For further information, see Figure 3 A grid 3011 is vertically arranged in the middle of the mobile bracket, and the grid 3011 can separate the mobile bracket into two parts, left and right. With this arrangement, the grid 3011 can push the frozen objects inside the mobile bracket to move during the movement of the mobile bracket, thereby ensuring the movement frequency of the frozen objects and improving the thawing effect.

[0064] In this embodiment, the first driving mechanism 401 is used to drive the first bearing mechanism 301 to perform linear motion, so as to realize linear drive of the frozen objects in the first thawing chamber 201. Accordingly, the first driving mechanism 401 can be any existing linear reciprocating driving mechanism, such as a crank slider mechanism, a gear rack mechanism, etc.

[0065] For details, see Figure 1 and Figure 4The first driving mechanism 401 is arranged in the installation room outside the first thawing chamber 201, and includes a first motor 4011, an eccentric 4012, a slide 4013, a guide rod 4014 and a connecting rod 4015. The first motor 4011 is vertically arranged in the installation room. Two guide rods 4014 are provided and extend along the length direction parallel to the thawing box 1. The slide 4013 is slidably sleeved on the two guide rods 4014 through a sliding hole, and a slide groove perpendicular to the guide rod 4014 is provided in the middle of the slide 4013. The eccentric 4012 can be an eccentric wheel, which is fixed on the rotating shaft of the first motor 4011, and a lever 4016 is fixedly connected to the eccentric 4012, and the lever 4016 extends downward into the slide groove. One end of the connecting rod 4015 is fixedly connected to the slide 4013, and the other end extends into the first thawing chamber 201 and is connected to the mobile bracket. In this way, the first motor 4011 can be started to drive the movable bracket to move back and forth.

[0066] Further, in this embodiment, a guide member is provided on the bottom and / or the outer side wall of the movable bracket, which is in rolling contact or sliding contact with the inner wall of the first thawing chamber 201. Figure 3 The bottom of the mobile bracket is provided with a plurality of rollers 3012. Such a configuration can reduce the movement friction between the mobile bracket and the inner wall of the first thawing chamber 201, and improve the smoothness of its movement.

[0067] In this embodiment, the second carrying mechanism 302 is mainly used for loading bottled frozen food. Specifically, the second carrying mechanism 302 includes a plurality of rotating clamping members rotatably arranged in the second thawing chamber 202, and the rotating clamping members are used for clamping the frozen food so that the frozen food can be driven to rotate.

[0068] For example, see Figures 5 to 7 In this embodiment, the rotating clamping member includes a rotating cylinder 3021, and the bottom of the rotating cylinder 3021 is sealed and rotated with the bottom of the second thawing chamber 202 through components such as a sealing bearing. The rotating cylinder 3021 is a hollow structure, and a plurality of elastic clamping pieces 30211 are arranged in the rotating cylinder 3021. The upper end of the elastic clamping piece 30211 is integrally formed with the cylinder body of the rotating cylinder 3021, and the lower end of the 30211 elastic clamping piece is a free end and extends obliquely to the inside of the rotating cylinder 3021. In this embodiment, the rotating cylinder 3021 is made of an elastic material, such as rubber, so that the elastic clamping piece 30211 has elasticity. In this way, when the frozen object is placed in the rotating cylinder 3021, the elastic clamping piece 30211 will be pressed outward, and the elastic clamping piece 30211 will apply an elastic clamping force to the frozen object, so that the frozen object is stably clamped in the rotating cylinder 3021.

[0069] In this embodiment, the second driving mechanism 402 is used to drive the second bearing mechanism 302 to rotate, so as to realize the rotation drive of the frozen objects in the second thawing chamber 202. Accordingly, the second driving mechanism 402 can be any existing rotation driving mechanism 4, for example, the motor directly drives the rotating drum 3021 to rotate.

[0070] For details, see Figure 5 In this embodiment, the second driving mechanism 402 includes a second motor 4021 and a synchronous transmission mechanism 4022 connected between each rotating clamp and the rotating shaft of the second motor 4021. The second motor 4021 is vertically fixed in the installation room, and the synchronous transmission mechanism 4022 can be a belt transmission mechanism, a gear transmission mechanism, a chain transmission mechanism, etc. Figure 5 , which exemplarily shows the implementation of the synchronous transmission mechanism 4022 as a belt transmission mechanism, the belt transmission mechanism specifically includes a driving pulley and a plurality of driven pulleys, the driving pulley is fixedly mounted on the rotating shaft of the second motor 4021, each driven pulley is located below the second thawing chamber 202 and is coaxially connected to each rotating clamping member through a connecting shaft, and the driving pulley and each driven pulley are connected through a synchronous belt transmission. In this way, the second motor 4021 can be started to drive each rotating clamping member to rotate through the belt transmission mechanism.

[0071] Further, in this embodiment, a support assembly 3022 is disposed in the second thawing chamber 202, and the support assembly 3022 includes a support frame 30221 and a plurality of fixing rings 30222 fixed on the support frame 30221. Figure 7 The support frame 30221 is a rectangular annular frame, and the support frame 30221 is fixed to the inner wall of the second thawing chamber 202 by a snap-on method. Each fixing ring 30222 is integrally formed inside the support frame 30221, and is arranged in sequence along the length direction of the support frame 30221. The fixing ring 30222 is a circular ring structure adapted to the shape of the rotating cylinder 3021, and the inner diameter of the fixing ring 30222 is equal to or slightly larger than the outer diameter of the rotating cylinder 3021. When the support frame 30221 is installed in the second thawing chamber 202, each fixing ring 30222 is respectively sleeved on each rotating cylinder 3021. In this way, the fixing ring 30222 can provide a guide for the rotation of the rotating cylinder 3021, avoid shaking of the rotating cylinder 3021 when rotating, and improve the rotation stability and smoothness of the rotating cylinder 3021.

[0072] In this embodiment, the internal circulation mechanism 5 is used to make the thawing medium circulate between the thawing chambers 2. Specifically, combined with the above-mentioned structural design of two thawing chambers 2, the internal circulation mechanism 5 of this embodiment is used to realize the internal circulation of the thawing medium between the first thawing chamber 201 and the second thawing chamber 202, so as to realize the flowing water thawing of frozen objects and improve the thawing efficiency of frozen objects.

[0073] Specifically, in this embodiment, the internal circulation mechanism 5 includes a first circulation mechanism for circulating the thawing medium of the first thawing chamber 201 to the second thawing chamber 202 and a second circulation mechanism for circulating the thawing medium of the second thawing chamber 202 to the first thawing chamber 201 .

[0074] Furthermore, the first circulation mechanism circulates the thawing medium from the lower part of the first thawing chamber 201 to the second thawing chamber 202, for example, see Fig. 9 , a drain port (port A) is provided on the bottom wall of the second thawing chamber 202 and connected to the inner circulation mechanism 5. The second circulation mechanism circulates the thawing medium located above the height of the second bearing mechanism 302 in the second thawing chamber 202 to the first thawing chamber 201. Such a setting is, on the one hand, to realize the up and down circulation of the thawing medium, so that the fluidity of the thawing medium is stronger and the thawing effect is improved; on the other hand, it is to enable the thawing medium in the second thawing chamber 202 to completely submerge the bottled frozen goods. Since the second thawing chamber 202 is mainly used to load bottled frozen goods, the bottled frozen goods need to be arranged vertically and a higher liquid level is required to submerge the bottled frozen goods. Therefore, the second circulation mechanism can only circulate the thawing medium from a position above the height of the second bearing mechanism 302 to the first thawing chamber 201 to ensure uniform and efficient thawing of the bottled frozen goods and ensure the thawing effect.

[0075] For details, see Figure 8 and Fig. 9 In this embodiment, the first circulation mechanism includes a circulation pipe (not shown) connected between the first thawing chamber 201 and the second thawing chamber 202 and a circulation pump 501 for pumping the thawing medium. In this way, the thawing medium can be circulated from the first thawing chamber 201 to the second thawing chamber 202 by pumping, and the stability is good. Figure 8 and Fig. 9 When in use, the thawing medium in the first thawing chamber 201 enters the first circulation mechanism from port A, and is pumped by the circulation pump 501 to port B and discharged into the second thawing chamber 202.

[0076] For further information, see Fig.10 In this embodiment, the first circulation mechanism also includes a water temperature regulating mechanism, which is arranged on the circulation pipe to regulate the temperature of the thawing medium circulated from the first thawing chamber 201 to the second thawing chamber 202. For example, the water temperature regulating mechanism can be a PTC water heater. This arrangement facilitates the control of the temperature of the thawing medium, realizes low-temperature thawing, and increases the circulation time of the thawing medium, avoiding frequent start and stop of the temperature regulating system.

[0077] In this embodiment, the second circulation mechanism includes an overflow structure disposed between the first thawing chamber 201 and the upper portion of the second thawing chamber 202. For example, see Figure 8 The overflow structure is an overflow notch 1011 disposed on the top of the partition wall 101. This arrangement can ensure that the second thawing chamber 202 is kept full of water, ensuring the thawing effect of the bottled frozen food, and does not require additional driving force to circulate the thawing medium, which can save equipment costs and energy costs. Fig. 9 When in use, the thawing medium in the second thawing chamber 202 circulates from the G port, ie, the overflow notch 1011, to the first thawing chamber 201. Of course, in other embodiments, the second circulation mechanism may also be a water pump and a water pipe.

[0078] In this embodiment, the temperature regulating system is used to regulate the temperature of the thawing medium in the thawing chamber 2, so that the thawing medium is kept within a specified low temperature range, maintaining a low temperature environment for the frozen food, keeping the frozen food fresh during the thawing process, and ensuring its quality after thawing.

[0079] Specifically, in this embodiment, the temperature regulation system includes a temperature detector and an external circulation mechanism 6. The temperature detector is in contact with the thawing medium of at least one thawing chamber 2 to monitor the temperature of the thawing medium in the thawing chamber 2 in real time, and the external circulation mechanism 6 is connected to at least one thawing chamber 2 to realize the external circulation of the thawing medium between the thawing chamber 2 and the external storage device.

[0080] More specifically, in this embodiment, the temperature detector can be a temperature sensor. Figure 8 and Fig. 9 In this embodiment, the temperature detector is disposed at the N port, which is connected to the M port in the first thawing chamber 201 through a flow channel, so that the temperature detector can detect the temperature of the thawing medium in the first thawing chamber 201 in real time. Of course, in other embodiments, the temperature detector can also be directly disposed inside the first thawing chamber 201.

[0081] The external circulation mechanism 6 is used to discharge the thawing medium in the thawing chamber 2 to the outside and inject the external thawing medium into the thawing chamber 2 according to the temperature data detected by the temperature detector. Figure 8 In this embodiment, the external circulation mechanism 6 includes a water inlet component 601, a water discharge component 602 and a controller.

[0082] The water inlet assembly 601 includes a water inlet pipe connected to the first thawing chamber 201, and the other end of the water inlet pipe is connected to an external storage device storing thawing medium. A first solenoid valve can be provided on the water inlet pipe to control on and off, and a water inlet pump can be provided to pump the thawing medium. The thawing medium can also be transported to the first thawing chamber 201 by using the pressure of the thawing medium in the storage device, for example, by using the water pressure of tap water itself. Figure 8 and Fig. 9When injecting liquid, the thawing medium is introduced from the C port and injected into the second thawing chamber 202 from the D port.

[0083] The drainage assembly 602 includes a water outlet pipe connected to the first thawing chamber 201, and the other end of the water outlet pipe is also connected to the storage device. A second solenoid valve can be provided on the water outlet pipe to control on and off, and a drainage pump can be provided to pump the thawing medium. Figure 8 and Fig. 9 When draining, the thawing medium is discharged from port E and discharged outward from port F into the storage device.

[0084] The controller is electrically connected to each solenoid valve, water pump and temperature detector. The controller can selectively control the opening and closing of each solenoid valve and water pump according to the temperature signal fed back by the temperature detector, thereby controlling the circulation of the thawing medium between the thawing box 1 and the storage device. Of course, the controller is also used to control each solenoid valve and water pump separately to inject the thawing medium into the thawing box 1 before thawing and discharge the thawing medium in the thawing box 1 after thawing. The controller can specifically select an existing programmable logic controller (PLC).

[0085] The low-temperature rapid thawing device provided in the above embodiment has the following operating principles:

[0086] 1) First, the frozen objects to be thawed are classified and placed in the movable bracket in the first thawing chamber 201 and the rotating drum 3021 in the second thawing chamber 202 .

[0087] 2) The controller controls the water inlet assembly 601 to open, and injects thawing medium into the second thawing chamber 202 through the water inlet pipe. When the second thawing chamber 202 is filled with thawing medium, the thawing medium will overflow into the first thawing chamber 201 until the thawing medium completely submerges the frozen objects in the first thawing chamber 201.

[0088] 3) The first drive mechanism 401, the second drive mechanism 402, the first circulation mechanism and the outer circulation mechanism 6 are turned on to thaw the frozen objects. During the thawing process, the first drive mechanism 401 drives the mobile bracket to move back and forth, so that the frozen objects in the mobile bracket move. The second drive mechanism 402 drives each rotating cylinder 3021 to rotate, so that the frozen objects in the rotating cylinder 3021 rotate. The first circulation mechanism circulates the thawing medium in the first thawing chamber 201 to the second thawing chamber 202, and the thawing medium in the second thawing chamber 202 overflows into the first thawing chamber 201. The outer circulation mechanism 6 is selectively turned on according to the temperature of the thawing medium in the thawing chamber 2. When the temperature of the thawing medium is too low, the thawing medium in the thawing chamber 2 is discharged to the outside, and the external thawing medium is injected into the thawing chamber 2 until the temperature of the thawing medium in the thawing chamber 2 rises to the specified temperature range again.

[0089] 4) After thawing is completed, the first drive mechanism 401, the second drive mechanism 402, the first circulation mechanism and the external circulation mechanism 6 are closed. Then the drainage assembly 602 and the first circulation mechanism are opened, the first circulation mechanism guides the thawing medium in the first thawing chamber 201 into the second thawing chamber 202, and the drainage assembly 602 discharges the thawing medium in the second thawing chamber 202 to the outside until the thawing medium in the thawing chamber is completely discharged.

[0090] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
