[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0030] like Figures 1-7 As shown, one embodiment of this utility model provides a meat preservation and grilling component, including a bamboo tube 1, a cap 2, multiple steel skewers 3, and a grease sealing mechanism. The bamboo tube 1 has an opening at its first end and a bamboo joint 101 at its second end. The cap 2 is inserted into the opening of the bamboo tube 1 and is lower than the end face of the first end of the bamboo tube 1. The cap 2 has multiple holes for the steel skewers 3 to pass through. The steel skewers 3 include a steel skewer body 301 and a ring body 302 connected to each other. The steel skewer body 301 passes through the holes on the cap 2, and the ring body 302 is blocked by the holes. The steel skewer body 301 is used to skewer meat pieces. The grease sealing mechanism is used to seal the opening of the bamboo tube 1.
[0031] In this embodiment, the meat preservation and grilling component can be used as a preservation container or directly for grilling.
[0032] Specifically, when using this meat preservation and grilling component as a storage container during transportation, the meat supplier needs to first cut the freshly slaughtered, grazing adult cattle, sheep, or pork into pieces about 2cm in size. Then, fry the meat pieces in mutton oil at approximately 200 degrees Celsius for 2-3 minutes to remove some moisture and ensure sterilization. Next, multiple steel skewers 3 are sequentially inserted through the holes in the cap 2. At this point, the skewer body 301 of the steel skewers 3 passes through the holes in the cap 2, while the ring 302 of the steel skewers 3 is blocked by the holes in the cap 2. The fried meat pieces are then skewered onto the steel skewer body 301. Next, the inside and outside of the bamboo tube 1 are sterilized. Then, the steel skewers 3 on the cap 2 are inserted into the inside of the bamboo tube 1, and the cap 2 is pushed forcefully to insert into the opening of the bamboo tube 1. Finally, a grease sealing mechanism is used to seal the gap between the cap 2 and the bamboo tube 1 to ensure a sealed interior. This way, the meat skewers can remain fresh for 15-30 days without freezing or adding preservatives, which is conducive to short-term (15-30 days) preservation at room temperature, meeting the time requirements for transportation. Moreover, using bamboo tubes as containers is more environmentally friendly and healthier than using plastic packaging.
[0033] When the user receives the goods from the meat supplier, they can use an open flame to grill the bamboo tube 1. The grease sealing mechanism drips through the holes on the cap 2 onto the meat skewers on the steel skewer body 301. The meat skewers then undergo a process of braising, smoking, and grilling over an open flame.
[0034] In this way, users can directly grill the meat skewers inside the bamboo tube 1 without having to defrost, wash, cut, and skewer them, which greatly reduces the user's time and labor costs, simplifies the grilling process, and improves grilling efficiency.
[0035] It should be noted that when the user roasts the bamboo tube 1 over an open flame, since the diameter of the steel skewer body 301 is smaller than the diameter of the hole on the cap 2, as the grease sealing mechanism melts, the internal air pressure of the bamboo tube 1 can be discharged through the gap between the steel skewer body 301 and the hole on the cap 2, thus avoiding safety accidents caused by the inability of the internal air pressure of the bamboo tube 1 to be discharged.
[0036] Furthermore, when the user grills the bamboo tube 1 over an open flame, as the temperature rises, the grease sealing mechanism melts and drips from the holes in the cap 2 onto the meat skewers on the steel skewer body 301. At this time, the meat skewers undergo simmering, smoking, and open-flame grilling. As the internal temperature of the bamboo tube 1 gradually increases, the meat skewers are in the simmering stage. As the bottom of the bamboo tube 1 is ignited first, smoke from the bottom of the bamboo tube 1 smokes the meat skewers on the steel skewer body 301. As the entire bamboo tube 1 gradually burns, the high temperature generated by the burning bamboo tube 1 grills the meat skewers, and at the same time, the smoke generated by the burning bamboo tube 1 also smokes the meat skewers.
[0037] As can be seen, the bamboo tube 1 in this embodiment can be used directly as a combustion material, which can save charcoal costs to a certain extent.
[0038] The above is only one processing method for meat skewers and does not include all processing methods. For example, the meat skewers inside the bamboo tube 1 can be processed by high-temperature steaming. Specifically, the bamboo tube 1 can be directly placed in a steamer and heated by high-temperature steam. As the temperature rises, the grease sealing mechanism melts and drips from the holes on the lid 2 onto the meat skewers on the steel skewer body 301. The meat skewers inside the bamboo tube 1 gradually heat up in the high-temperature environment.
[0039] In this embodiment, the grease sealing mechanism is a sealing layer formed of mutton fat or beef tallow. The melting point of mutton fat is typically between 42°C and 48°C, while the melting point of beef tallow is typically between 40°C and 60°C. At room temperature (generally around 20°C), both mutton fat and beef tallow are solid. Considering cost, mutton fat is preferred.
[0040] The space enclosed by the top surface of the lid 2 and the inner wall of the bamboo tube 1 is the sealing space. After the meat skewer on the steel skewer 3 is inserted into the bamboo tube 1 and the lid 2 is inserted into the opening of the bamboo tube 1, liquid hot mutton fat at about 50°C is poured over the lid 2. The liquid hot mutton fat accumulates in the sealing space on the top surface of the lid 2. Then, the bamboo tube 1 is placed in a refrigerator or freezer to accelerate the cooling of the mutton fat. Once the mutton fat has solidified, the bamboo tube 1 is removed. At this point, if... Figure 2 and Figure 3 As shown, a layer of mutton fat sealing 4 is formed on the top surface of the cap 2. Simultaneously, the gap between the side of the cap 2 and the inner wall of the bamboo tube 1 is completely sealed with mutton fat. The gap between the steel skewer body 301 and the hole on the cap 2 is also blocked by mutton fat. This ensures the meat skewers are in a completely sealed environment, preventing contact with the external environment and guaranteeing shelf life. The mutton fat sealing layer 4 should be approximately 5mm thick.
[0041] To further improve the sealing effect, such as Figure 2 and Figure 3 As shown, oil paper 5 is laid on the top surface of the mutton fat sealing layer 4. Thin cotton rope can be used to tie the outside of the bamboo tube 1 to secure the oil paper 5. It should be clear that the oil paper 5, in addition to improving the sealing effect, can also serve as an ignition source. Specifically, when the bamboo tube 1 is roasted over an open flame, the oil paper 5 can be lit, and the burning of the oil paper 5 accelerates the melting of the mutton fat sealing layer 4.
[0042] In this embodiment, as Figure 7As shown, the cap 2 is shaped like a frustum, meaning its diameter gradually decreases from high to low. This allows the cap 2 to be inserted more tightly into the top opening of the bamboo tube 1, ensuring a proper seal. It should be noted that since the bamboo tubes 1 vary in size, the cap 2 must be manufactured to the appropriate size for each bamboo tube 1.
[0043] Optionally, the cover 2 can be either a wooden cover or a bamboo cover.
[0044] As a specific embodiment, this meat preservation and grilling assembly is also equipped with corresponding hanging wires 7. The function of these hanging wires 7 is to allow the user to simultaneously suspend multiple steel skewers 301 while grilling the bamboo tube 1.
[0045] Specifically, such as Figure 6 As shown, when grilling the bamboo tube 1, a suspension wire 7 is threaded through the rings 302 on multiple steel skewers 3, and then both ends of the suspension wire 7 are tied to a support to suspend the bamboo tube 1 directly above the grill. This way, after the bamboo tube 1 and the lid 2 have burned completely, all the steel skewers 3 and the pieces of meat on them remain suspended by the suspension wire 7. This prevents the steel skewers 3 from falling and allows all the skewers 3 to be removed at once.
[0046] It needs to be clear that, such as Figure 4 As shown, the lines connecting the multiple holes on the cover 2 are distributed in a wavy pattern. This way, after the suspension wire 7 passes through the rings 302 on the multiple steel skewers 3 in sequence, the two ends of the suspension wire 7 can be kept in the same horizontal straight line as much as possible, so that the two ends of the suspension wire 7 can be tied to the supports on both sides of the barbecue grill later.
[0047] Optionally, after the meat skewers are processed by steaming or boiling, the lid 2 is tightly inserted into the top opening of the bamboo tube 1, making it difficult to remove. Therefore, in this embodiment, a handle mechanism is installed on the top surface of the lid 2. The handle mechanism includes a pull wire 6. Two round holes are formed on the top surface of the lid 2, and both ends of the pull wire 6 pass through these holes. The two ends of the pull wire 6 are then knotted to prevent it from detaching from the lid 2. Thus, after the meat skewers are processed by steaming or boiling, the pull wire 6 can be pulled to remove the lid 2. Then, the lid 2, along with the steel skewers 3, can be removed from the bamboo tube 1. The meat pieces on the steel skewers 3 are then removed from the skewer body 301 and placed into a container. Finally, the steel skewers 3 can be pulled out from the holes in the lid 2.
[0048] Specifically, there are two handle wires 6 installed, and the two handle wires 6 are symmetrically arranged about the axis of the cover 2.
[0049] Optionally, the steel skewer 3 used in this embodiment is a food-grade steel skewer 3, such as one made of 304 stainless steel or 316 stainless steel.
[0050] When preparing meat for transportation using this meat preservation and grilling kit: First, the meat supplier needs to cut the meat (pork, beef, or lamb, etc.) for the day into pieces about 2cm in size. Then, seasonings or marinating can be used selectively to create different flavors for the skewers. Next, fry the meat pieces in mutton oil at approximately 200 degrees Celsius for 2-3 minutes to remove some moisture and ensure sterilization. Then, sterilize the inner and outer surfaces of the bamboo tube 1, the cap 2, and the steel skewers 3 separately. Sterilization methods include, but are not limited to, high-temperature steam sterilization, ultraviolet sterilization, and irradiation sterilization. Then, multiple steel skewers 3 are passed through the holes in the cap 2, and the fried meat pieces are skewered onto the steel skewer body 301. Immediately afterward, insert the steel skewers 3 from the cap 2 into the inside of the bamboo tube 1 and push the cap 2 firmly so that it is inserted into the opening of the bamboo tube 1. Next, pour liquid hot mutton oil at approximately 50 degrees Celsius over the cap 2 and place the bamboo tube 1 in a refrigerator or freezer to accelerate the cooling of the mutton oil. After the mutton fat has solidified, remove the bamboo tube 1 from the refrigerator or freezer. Then, place oil paper 5 on top of the mutton fat sealing layer 4 and tie it to the outside of the bamboo tube 1 with thin cotton rope to secure the oil paper 5. This completes the preparation work before transportation.
[0051] Using this meat preservation and grilling kit to preserve meat for grilling has the following advantages: First, the meat does not need to be frozen or transported by refrigerated trucks, resulting in low cost and short-term (15-30 days) preservation at room temperature. Second, it can maintain its freshness for 15-30 days without the need for preservatives. Third, using bamboo tubes as containers is more environmentally friendly and healthier than using plastic packaging.
[0052] After receiving the bamboo tube 1 containing the meat skewers, the user can cook them using methods such as grilling or steaming. This embodiment only describes how to cook by grilling:
[0053] First, the hanging wire 7 is threaded through the rings 302 on multiple steel skewers 3. Then, the two ends of the hanging wire 7 are tied to the supports on both sides of the barbecue grill, suspending the bamboo tube 1 directly above the grill. At this time, the charcoal on the grill smokes the bottom of the bamboo tube 1, and then the oil paper 5 on the top of the bamboo tube 1 is ignited. As the temperature rises, the mutton fat sealing layer 4 melts and drips down the holes on the cap 2 onto the meat skewers on the steel skewers 301. The bamboo tube 1 and the cap 2 gradually burn, until only the steel skewers 3 and the meat pieces on the steel skewers remain, suspended on the hanging wire 7. At this point, salt or other seasonings, such as cumin, can be sprinkled on the meat pieces. Finally, the user simply removes the hanging wire 7 and pulls it out of the steel skewers 3 to obtain the grilled meat skewers.
[0054] Using this meat preservation and grilling kit to grill meat chunks has the following advantages: First, since the meat chunks have been pre-washed, cut into pieces, and skewered, users do not need to perform the defrosting, washing, cutting, and skewering operations again, greatly reducing the user's time and labor costs, simplifying the grilling process, and improving grilling efficiency. Second, the bamboo tube 1 and the lid 2 can be used as grilling fuel, thereby saving costs.
[0055] Furthermore, the meat preservation and grilling components used in this invention have a simple structure and low cost. They can be used for short-term preservation during transportation or for direct grilling, making them highly practical.
[0056] Finally, compared with plastic packaging, bamboo tube 1 and wooden or bamboo cap 2 can avoid the risk of microplastic pollution; during use, bamboo tube 1, mutton fat sealing layer 4 and oil paper 5 are used as barbecue fuel, and steel skewers 3 can be recycled and reused, without causing additional solid waste environmental impact.
