Description
Technical Field
[0001] The present application relates to the field of quick-frozen vegetable processing technology, and in particular to a quick-frozen vegetable vacuum freezer. Background Art
[0002] Quick-frozen vegetables are vegetables that are processed by the quick freezing method. The processing process includes quick-freezing the vegetables at a temperature of minus 30-35 degrees Celsius or lower, and then packaging and storing them to prevent the growth and reproduction of microorganisms and the activity of enzymes, so that the vegetables can be preserved for a longer period of time.
[0003] Usually, vegetables are quickly frozen using a vacuum freezer, which includes a vacuum chamber, an electronic control system, a vacuum system, and a cooling system. When freezing, the vegetables are placed in a vacuum chamber, the door is closed, and the vacuum system and cooling system are started through the electronic control system. The vacuum system extracts the air from the vacuum chamber. As the air pressure continues to drop, the boiling point of water continues to drop and evaporates. When the air pressure drops to about 610 Pa, the water temperature drops to zero and begins to freeze. The cooling system is installed between the vacuum exhaust port and the vacuum chamber to quickly condense the evaporated water molecules into water, so as to promote the evaporation of water in the vacuum chamber while protecting the vacuum system.
[0004] The vegetables sent into the vacuum chamber are often collected in collection boxes after leaving the previous process. The distribution of vegetables in these collection boxes is generally uneven. If the vegetables are transported to the vacuum chamber directly through these collection boxes, the evaporation rate of water in the vegetables at different positions will vary greatly, resulting in lower product quality of quick-frozen vegetables.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-4 This application is described in further detail.
[0033] The embodiment of the present application discloses a vacuum freezer for quick-frozen vegetables.
[0034] Example 1
[0035] Reference Figure 1 A quick-frozen vegetable vacuum freezer comprises a vacuum chamber 1, a vacuum system 2, a cooling system 3 and an electric control system 4. The vacuum system 2 is arranged in the vacuum chamber 1, and is used to extract the gas in the vacuum chamber 1. The cooling system 3 is installed between the vacuum exhaust port and the vacuum chamber 1, and is used to condense the evaporated water molecules into water.
[0036] A plurality of trays 5 are installed in the vacuum chamber 1 in a detachable and washable manner by pulling out. The plurality of trays 5 are extended along the height direction of the vacuum chamber 1 , and the trays 5 are used to place vegetables to be processed.
[0037] A pusher 6 and a driving assembly 7 are installed in the vacuum chamber 1. The pusher 6 is connected to the driving assembly 7. The driving assembly 7 is used to drive the pusher 6 to move horizontally. The pusher 6 pushes the higher vegetables in the tray 5 flat during the horizontal movement. There are multiple pushers 6, and the multiple pushers 6 correspond to the multiple trays 5 one by one.
[0038] The end of the pusher 6 is connected to a first connecting rod 61 , and the first connecting rod 61 is arranged horizontally.
[0039] Reference Figure 1 and Figure 2The driving assembly 7 includes a second connecting rod 71, a screw rod 72 and a rotating motor 73. The second connecting rod 71 is extended along the height direction of the vacuum chamber 1, and the upper and lower ends of the second connecting rod 71 are integrally formed with sliding blocks 711. The top and bottom surfaces of the vacuum chamber 1 are provided with sliding grooves 11 for sliding connection of the sliding blocks 711, and the sliding grooves 11 are extended along the width direction of the vacuum chamber 1.
[0040] The screw rod 72 is rotatably connected to the inner wall of the vacuum chamber 1, and the screw rod 72 is extended along the width direction of the vacuum chamber 1. The second connecting rod 71 is penetrated by a screw hole 712 for the screw rod 72 to be threaded. The rotary motor 73 is connected to the vacuum chamber 1, and the output shaft of the rotary motor 73 is connected to the screw rod 72. When the vegetables are quick-frozen, the vegetables to be processed are first placed on the tray 5, and then the tray 5 is placed in the vacuum chamber 1; then the rotary motor 73 is started, and the rotary motor 73 drives the screw rod 72 to rotate. During the rotation of the screw rod 72, the pusher 6 is driven to move along the width direction of the vacuum chamber 1. During the movement of the pusher 6, the uneven vegetables in the tray 5 are flattened, so that the distribution of the vegetables in the tray 5 is relatively uniform, so that the evaporation rate of the water in the vegetables in the tray 5 is relatively uniform, thereby improving the product quality of the quick-frozen vegetables.
[0041] Among them, in this embodiment, the pusher 6 is a roller-shaped structure, so that the contact area between the pusher 6 and the vegetables can be smaller while effectively flattening the vegetables, thereby reducing the risk of damage to the vegetables.
[0042] Furthermore, the pusher 6 is rollingly connected to the first connecting rod 61, and the axis of the pusher 6 rolling is its own central axis, thereby further reducing the mutual friction between the pusher 6 and the vegetables, thereby reducing the risk of damage to the vegetables.
[0043] Furthermore, the first connecting rod 61 and the second connecting rod 71 are detachably connected to realize the detachability of the pushing member 6 and the second connecting member, so as to facilitate replacement of different pushing members 6 according to different vegetable volumes, thereby improving the use flexibility of the vacuum freezer.
[0044] Reference Figure 3 The specific structure of the detachable connection between the first connecting rod 61 and the second connecting rod 71 is as follows: a plurality of connecting screws 713 are provided on the side wall of the second connecting rod 71, and the connecting screws 713 are threadedly connected with the threaded sleeves 714. An external thread is provided on the peripheral side of the first connecting rod 61, and the external thread is threadedly matched with the threaded sleeves 714. When the pusher 6 is connected to the second connecting rod 71, the first connecting rod 61 is firstly abutted against the connecting screws 713, and then the threaded sleeves 714 are screwed to connect the first connecting rod 61 to the threaded sleeves 714.
[0045] To facilitate positioning between the first connecting rod 61 and the connecting screw 713 , an inserting groove 611 is provided on the end surface of the first connecting rod 61 close to the connecting screw 713 , and an inserting rod 715 for cooperating with the inserting groove 611 is fixedly connected to the end surface of the connecting screw 713 close to the first connecting rod 61 .
[0046] The implementation principle of Example 1 is: when processing quick-frozen vegetables, first place the tray 5 containing the vegetables in the vacuum chamber 1, and then close the door of the vacuum chamber 1; then start the vacuum system 2, the cooling system 3 and the rotating motor 73 through the electronic control system 4.
[0047] The rotating motor 73 drives the screw rod 72 to rotate, and when the screw rod 72 rotates, it drives the second connecting rod 71 to move along the width direction of the vacuum chamber 1, thereby driving the pusher 6 connected to the second connecting rod 71 to move along the width direction of the vacuum chamber 1. During the movement of the pusher 6, the vegetables with a higher height placed in the tray 5 are flattened, so that the vegetables in the tray 5 are distributed relatively evenly, thereby improving the uniformity of the evaporation rate of water in each part of the vegetables, thereby improving the product quality of the quick-frozen vegetables.
[0048] Example 2
[0049] Reference Figure 4 The side wall of the pusher 6 is fixedly connected with a plurality of flipping members 62, which are arranged to extend radially along the pusher 6, and are evenly distributed around the pusher 6. When the pusher 6 moves along the width direction of the vacuum chamber 1 and pushes the vegetables in the tray 5 flat, as the pusher 6 rotates, a part of the flipping members 62 is inserted into the vegetables, and another part of the flipping members 62 is turned out from the vegetables. While the pusher 6 pushes the vegetables flat, it also plays a certain flipping role, so that the evaporated water of the vegetables at the bottom can move upward faster, further improving the uniformity of the evaporation rate of the water and improving the product quality of the quick-frozen vegetables.
[0050] It is worth noting that the structure of this embodiment is suitable for vegetables with greater hardness, such as potato cubes, carrot cubes, etc. In order to reduce the risk of damage to the vegetables, the turning member 62 is made of relatively soft silicone.
[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
