Description

Technical Field

[0001] The utility model relates to the technical field of quick-freezing machines, in particular to a double-spiral quick-freezing machine used for processing mussels. Background Art

[0002] A quick freezer is a device that quickly freezes food through a refrigeration system. It is widely used in the food freezing industry. When it comes to solid ingredients such as fruits and vegetables, it has the advantages of keeping the nutrients in the food intact and keeping the taste fresh. However, when it comes to ingredients with moisture, such as shelled mollusks such as snails and mussels, traditional quick freezers cannot penetrate the shells of the ingredients and freeze them in a short time. The mucus produced by the mollusks will contaminate the transportation equipment. Therefore, a quick freezer that can completely freeze crustacean ingredients such as mussels is needed.

[0003] Chinese patent CN214536981 U discloses a double spiral quick freezer for frozen products, which is provided with a freezing box, a refrigeration device and a conveyor belt. A sliding door is provided at one end of the freezing box, a first servo motor is fixed on one side of the top of the freezing box, and a second rotating shaft is fixed at the bottom of the second servo motor. The utility model is provided with a feeding mechanism above the feeding end of the double spiral quick freezer. When in use, the operator can first add the products to be frozen into the storage box uniformly. After that, when it is necessary to feed and freeze, it is only necessary to control the electric telescopic rod. When the electric telescopic rod is contracted, the baffle inside the drop tube can be pulled to open the channel of the drop tube. At this time, the products in the storage box can fall onto the conveyor belt below for transportation. When the operator controls the electric telescopic rod to extend and reset, the internal channel of the drop tube can be closed, and the products will not fall onto the conveyor belt, thereby realizing the convenience of feeding the double spiral quick freezer. At the same time, the double spiral structure increases the freezing time in disguise and improves the freezing effect.

[0004] There are still several points for improvement in the above documents: lack of cleaning ability, long-term use is prone to pollution; the heat generated by the refrigeration system is directly discharged, wasting energy. Utility Model Content

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figure 1 to Figure 6 As shown, a double spiral quick-freezing machine for mussel processing includes a transport component 1, a spiral frame 6 and a refrigerator 7. The transport component 1 includes a rotating wheel 2, a crawler 4, a tray 3 and a water spray pipe 5. Two spiral frames 6 are respectively arranged on both sides of the refrigerator 7. The transport component 1 is connected to the spiral frame 6. Two rotating wheels 2 are respectively arranged on both sides of the refrigerator 7. The crawler 4 covers the entire spiral frame 6 and is rotatably connected to the rotating wheel 2. The tray 3 is horizontally installed on the crawler 4. The tray 3 is hung on the crawler 4 between the two rotating wheels 2. Two water spray pipes 5 are connected to the bottom of the refrigerator 7. One end of the water spray pipe 5 is directly below the crawler 4 between the two rotating wheels 2 and is aligned with the inverted tray 3.

[0026] The device connects the transport component 1 with the spiral frame 6, and uses the refrigerator 7 to blow cold air to the spiral frame 6 to cool the mussels transported on the spiral frame 6. The tray 3 is used to load the mussels. The transport path starts from the turntable 2 at one end and ends at the turntable 2 at the other end. During the transportation of the mussels, the tray 3 is always placed flat on the track 4. The rotation of the turntable 2 drives the track 4 to pull the tray 3 to move on the spiral frame 6. The spiral structure of the spiral frame 6 can increase the contact time between the tray 3 and the cold air blown out of the refrigerator 7, thereby improving the refrigeration effect. After the transportation is completed, the tray 3 is upside down on the track 4 due to the action of gravity. When the upside-down tray 3 passes between the two water spray pipes 5, it is impacted by the water flow to wash away the mussel mucus and attached dust remaining on the tray 3. Then the upside-down tray 3 passes through the turntable 2 again and is placed flat on the track 4 for the next transportation.

[0027] See also Figure 1 to Figure 3 As shown, the tray 3 includes a screen 31, a connecting hole 32, a spring 33 and a button 34. The screen 31 is arranged at the center of the tray 3, the connecting hole 32 is arranged on one side of the tray 3, the spring 33 is installed in the connecting hole 32, one end of the button 34 is connected to the spring 33, and the other end is connected to the track 4.

[0028] The screen 31 is used to improve the permeability of the tray 3 to facilitate cleaning by the water spray pipe 5. The connecting hole 32 is used to provide installation positioning for the button 34 and the spring 33. The button 34 squeezes the spring 33 to remove the tray 3 from the track 4, which is convenient for maintenance and replacement of the tray 3.

[0029] See also Figure 3 As shown, the crawler 4 includes handrails 41 and grooves 42 . The handrails 41 are a pair and are respectively installed on both sides of the crawler 4 . The grooves 42 are arranged on opposite sides of the two handrails 41 and are rotatably connected to the tray 3 .

[0030] The function of the handrail 41 is to prevent the pallet 3 from falling off when passing through the spiral frame 6. The groove 42 is rotatably connected to the button 34 on the pallet 3, which reinforces the installation of the pallet 3 and enables the pallet 3 to be hung upside down on the crawler 4 after completing the transportation work.

[0031] See also Figure 1 to Figure 6 As shown, the water spray pipe 5 includes a water gun 51 and a rotating shaft 52 . The rotating shaft 52 is rotatably connected to the top end of the water spray pipe 5 and is located directly below the crawler track 4 . The water gun 51 is mounted on the rotating shaft 52 .

[0032] The water gun 51 is used to increase the water pressure of the water spray pipe 5 to improve the cleaning effect. The rotation of the shaft 52 can adjust the cleaning angle of the water gun 51. Since the tray 3 is upside down, the sewage after cleaning can automatically fall under the action of gravity, further improving the cleaning effect and efficiency.

[0033] See also Figure 1-2As shown, the spiral frame 6 includes a support frame 61, a support rod 62 and a column 63. The column 63 is installed at the spiral center of the spiral frame 6. The support frame 61 is installed around the column 63. One end of the support rod 62 is connected to the support frame 61, and the other end is connected to the column 63.

[0034] The upright column 63 provides a rotation fulcrum for the spiral frame 6 , while the support frame 61 and the support rod 62 strengthen the rigid structure of the spiral frame 6 , increase the load-bearing capacity, and prevent the spiral frame 6 from being deformed due to the weight of the tray 3 and the mussels.

[0035] See also Figures 4 to 6 As shown, the refrigerator 7 includes a fan 71, a cold air hole 72, a heat exchange fin 73 and a compressor 74. The fan 71 is installed on the side of the refrigerator 7 and faces the spiral frame 6. The cold air hole 72 is arranged on the side of the refrigerator 7 on the same side as the fan 71. The heat exchange fin 73 is installed on the side of the refrigerator 7. The compressor 74 is installed at the bottom of the refrigerator 7 and is connected to the water spray pipe 5.

[0036] The refrigerator 7 provides low-temperature cold air through the compressor 74 and the heat exchange fins 73 and discharges it through the cold air holes 72. The fan 71 is used to adjust the direction of the cold air so that the cold air is aimed at the spiral rack 6. At the same time, the hot water generated by the heat exchange fins 73 after hot and cold conversion is used as the water flow source in the water spray pipe 5 for cleaning the tray 3.

[0037] See also Figure 1 to Figure 5 As shown, the heat exchange fin 73 includes a needle tube 731 and a transverse tube 732 . The needle tube 731 passes through the heat exchange fin 73 and is connected to the cold air hole 72 on the compressor 74 . The transverse tube 732 is perpendicular to the direction of the needle tube 731 and passes through multiple heat exchange fins 73 .

[0038] The needle tube 731 is used to collect the cold air displaced on the heat exchange fins 73 and transfer the cold air into the cold air hole 72. The transverse tube 732 is used to collect the hot water displaced on the heat exchange fins 73 and send it to the compressor 74 and finally to the water spray pipe 5.

[0039] See also Figure 6 As shown, the compressor 74 includes a water inlet pipe 741, a water supply pipe 742 and a connecting pipe 743. The water inlet pipe 741 is installed on the side of the compressor 74, the water supply pipe 742 connects the compressor 74 with the heat exchange fins 73, and one end of the connecting pipe 743 is installed on the compressor 74, and the other end is connected to the water spray pipe 5.

[0040] The water source enters the compressor 74 through the water inlet pipe 741 to form low-temperature and low-pressure steam, which is then gathered by the heat exchange fins 73 to form cold air and hot water. The hot water returns to the compressor 74 through the water pipe 742, and is pressurized by the compressor 74 and sent to the water spray pipe 5 through the connecting pipe 743. The high-pressure hot water can effectively melt the frozen crystals remaining on the tray 3 and remove them.

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
