Description

Technical Field

[0001] The invention relates to the technical field of pre-prepared meal production equipment, and in particular to a quick freezing device for pre-prepared meal production. Background Art

[0002] Pre-prepared food, also known as pre-prepared conditioned food, generally refers to semi-finished or finished products made from various agricultural, livestock, poultry and aquatic products as raw materials, seasonings and other auxiliary materials (including food additives), and processed through pre-selection, modulation and other processes. Usually, pre-prepared food needs to be stored or transported under cold chain conditions for consumers or catering processors to simply heat or cook before eating, but it will increase the risk of hyperlipidemia.

[0003] During the production process of some pre-prepared meat dishes, liquid nitrogen quick-freezing machines are generally used to transport and quick-freeze the pre-prepared dishes. The quick-frozen pre-prepared dishes need to be collected. When the collection box is full, manual unloading is required before continued transportation and collection can be carried out. There is an idle period in the middle, which reduces the quick-freezing efficiency. After the collection box is full, the empty collection box cannot be automatically switched for collection, which reduces the degree of automation. When the pre-prepared dishes are transported after packing, the quick-freezing effect is greatly reduced. Summary of the invention

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. A conveying platform is provided at a position below the discharge port of the quick-freezing discharge barrel. The conveying platform transports the collection box forward. After being transported to the position of the discharge port, the pre-prepared dishes fall into the storage box in turn after being quickly frozen. As the storage box is pushed forward, it directly falls into the corresponding collection box, and then is transported forward in turn as the conveying platform transports it. The collection box that is transported over can be blocked by the baffle bars provided at both sides of the bottom of the horizontal frame plate close to the support platform. Under the action of the telescopic movement generated between the first cylinder and the first gas rod, the lifting movement of the baffle bar is realized. During the lifting movement, the collection box that is transported over can be pushed step by step, so that the collection box can be evenly transported forward and the collection box can be continuously collected. Compared with the existing manual operation, the idle period between manual unloading and collection is effectively avoided, and the quick-freezing effect is maintained.

[0016] 2. A corrugated plate is arranged on both sides of the quick-freezing blanking barrel. The corrugated plate is made of soft material. The wave folded pattern of the corrugated plate can provide a certain buffering effect when blanking, so as to avoid the straight barrel blanking speed being too fast during blanking, which may easily cause blockage and accumulation at the bottom. In addition, the wave folded pattern of the corrugated plate can increase the buffering effect formed by the blanking, thereby increasing the rest time of the pre-prepared food inside the blanking channel, and increasing the time that the pre-prepared food contacts the cold air.

[0017] 3. By adopting a double-layer quick-freezing barrel, the preservation effect of the internal cold air can be improved. When the linkage mechanism in the side groove is driven, wind movement will be generated. Under the action of wind movement, the fluidity of the internal cold air will be improved, ensuring that every corner inside can be better exposed to the impact of cold air.

Among them, a baffle can be provided at the bottom of the limiting plate 20, that is, at the right edge end below the window hole 21. When the storage box 3 is pushed forward and hits the baffle, the top opening of the storage box 3 corresponds to the window hole 21, and the bottom opening of the storage box 3 corresponds to The material storage box 3 is a through-type structure facing the collection box 10 below, and the quick-freezing material barrel 5 is provided with columns 24 on both sides, and a sandwich 25 is formed between the columns 24 and the inner wall of the quick-freezing material barrel 5, and a refrigerator 26 is provided in the sandwich 25. The columns 24 are provided with a plurality of hollow side grooves 27, and the side grooves 27 are provided with linkage mechanisms 28. The middle part of the quick-freezing material barrel 5 is provided with a through-type material dropping channel 29, and the material dropping channel 29 is provided with corrugated plates 30 on both sides. The linkage mechanism The structure 28 includes a cylinder 31, a shaft is inserted in the middle of the cylinder 31, and the shaft is movably connected to the lower side of the side groove 27. The surface of the cylinder 31 is provided with shaking plates 32 on both sides, and the two ends of the bottom outer side of the shaking plate 32 are provided with support plates 33. A connecting shaft 34 is provided between the support plates 33. A sleeve 35 is sleeved on the connecting shaft 34. A driving rod 36 is provided at the center of the bottom wall of the sleeve 35. A connecting end 37 is provided at the bottom of the driving rod 36. The connecting ends 37 are respectively arranged on the top of the corresponding shaking plate 32 below. A plurality of refrigeration pipes 38 are provided on the top of the shaking plate 32, and the connecting end 37 is located between the refrigeration pipes 38. A limiting shaft 39 is provided on the upper part of the side groove 27 and located above the inner shaking plate 32. The inner cross-section of the shaking plate 32 becomes smaller from bottom to top, and the inner side of the shaking plate 32 located at the innermost bottom contacts the outer wall of the corrugated plate 30 arranged on the side. The top wall of the corrugated plate 30 is fixed on the inner top wall of the quick-freezing blanking barrel 5, and the bottom wall of the corrugated plate 30 is fixed on the inner bottom wall of the quick-freezing blanking barrel 5.

[0036] The quick-freezing blanking barrel 5 is set to a double-layer structure, and a refrigerator 26 is set in the cavity of the interlayer 25 of the double-layer structure. The cold air generated by the refrigerator 26 will pass through several side grooves 27 and be transmitted to the blanking channel 29. The cold air rushing into the blanking channel 29 will enter the interlayer 25 from the side grooves 27 to form a cycle. Corrugated plates 30 are set on both sides of the blanking channel 29. There are several air holes between the adjacent wrinkles of the corrugated plates 30, and air-permeable membranes are set at the air holes, so that the cold air generated inside can flow through the inside of the quick-freezing blanking barrel 5, so that the inside of the blanking channel 29 always maintains a certain cold temperature, and the pre-prepared dishes falling inside are always exposed to the impact of cold air when the materials are dropped.

[0037] The cross-sectional dimensions of the shaking plate 32 near the material drop channel 29 decrease from bottom to top. The inner side of the lowest shaking plate 32 presses against the outer wall of the inner corrugated plate 30, causing the lower part of the corrugated plate 30 to protrude into the material drop channel 29. When the prepared food above falls, it will hammer against the inner wall of the corrugated plate 30, and the inner wall will be driven downward by the hammering force. After the shaking plate 32 is hammered, the driving rod 36 connected to the side will drive the shaking plate 32 above in turn. After the angle of the shaking plate 32 changes, it will deform against the corrugated plate 30. After the corrugated plate 30 is deformed, the wrinkles of the side wall will change. After the corrugated pattern changes, the buffering effect will also change, avoiding the phenomenon of blockage and accumulation during the internal material drop process.

[0038] Detailed usage and function of this embodiment:

[0039] The collecting boxes 10 are placed on the conveying platform 8 in sequence, wherein the conveying platform 8 is an existing structure. When the collecting box 10 is conveyed forward to a position close to the blanking opening of the middle slot 2, the first cylinder 11 and the first gas rod 12 are driven to generate telescopic movement. When the first gas rod 12 is telescoped into the first cylinder 11, the baffle 15 arranged in front of the bottom wall of the cross frame plate 14 blocks the conveyed collecting box 10 downward, and the rear baffle 15 blocks the collection box 10 at the rear. In this way, there is a certain distance between the collecting box 10 in front and the collecting box 10 at the rear. When the pre-prepared dishes are put into the quick-freezing blanking barrel 5, the pre-prepared dishes will hit the corrugated plates 30 on both sides of the blanking channel 29. After being hit, the corrugated plates 30 press the protruding shaking plates 32 at the bottom. After the bottom shaking plate 32 is hit, the bottom shaking plate 32 will tilt up. Fig. 9In the process, the left top surface of the lowest shaking plate 32 is downward, while the right top surface is tilted upward. After tilting, the driving rod 36 on the right top surface of the lowest shaking plate 32 pushes against the upper shaking plate 32. In this way, the upper shaking plate 32 is pushed up to form a horizontal plane state, prompting the inner wall of the corrugated plate 30 to form multiple layers protruding toward the middle. The corrugated plate 30 will be deformed, so that the corrugated plate 30 forms a fault shape, and only a small part of the protruding part is formed. Therefore, when the pre-prepared dish is dropped from the material When the pre-prepared food falls down from the bottom of the material dropping channel 29, it will have a certain blocking effect and a buffering effect. When the pre-prepared food falls directly from the bottom of the material dropping channel 29 into the material storage box 3 just facing below, then the second cylinder 7 and the second gas rod 6 are driven to produce a telescopic movement. The second gas rod 6 pushes the material storage box 3 forward in the middle groove 2 until it is pushed to the top of the collection box 10 on the conveying platform 8. Since the material storage box 3 is connected from top to bottom, when the material storage box 3 is pushed to the top of the collection box 10 After that, the pre-prepared vegetables in the storage box 3 will directly fall into the collection box 10 below, and the top surface of the connecting plate 22 will just block the lower feeding port of the quick-freezing feeding barrel 5 as it is pushed. Then, the third cylinder 17 and the third gas rod 18 are driven to produce telescopic movement, and the third gas rod 18 will press the pressing plate 19 downward, and the pressing plate 19 passes through the window hole 21 to press the pre-prepared vegetables in the storage box 3 to prevent the pre-prepared vegetables from adhering to the inner wall of the storage box 3, and press the pre-prepared vegetables in the storage box 3 down and fall into the collection box 10. After the collection box 10 is in the middle, the third gas rod 18 is extended and retracted into the third cylinder 17, and the storage box 3 is pulled back into the middle groove 2 along with the second gas rod 6, and then the first cylinder 11 and the first gas rod 12 are driven to produce a telescopic movement, prompting the first gas rod 12 to push the cross frame 14 upward, and the blocking rod 15 will go up. At this time, the intercepted collection box 10 will be transported forward, and the collection box 10 behind will be transported forward, and then the above operation is repeated, so as to prompt the collection box 10 to pack the pre-prepared dishes in sequence and then transport them.

[0040] Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
