Description

Technical Field

[0001] This utility model relates to the field of pickling equipment technology, and in particular to a pickling equipment for microbial fermentation. Background Technology

[0002] Microbial fermentation is a biochemical process in which microorganisms (such as bacteria, yeast, and fungi) convert organic matter into other compounds during their metabolism. In the process of curing pork, salt and spices are added after microbial fermentation for further curing.

[0003] Salt often clumps after prolonged storage, and its large particles require grinding before it can be used for marinating pork. For example, Chinese Patent Publication No. CN216778690U discloses a marinating device for microbial fermentation, including a marinating tank body, a second sealing cover, and a box body. The top of the marinating tank body is equipped with a first sealing cover. In this invention, the combined use of the box body, grinding disc, conical platform, crank handle, micropores, first grinding protrusions, and second grinding protrusions facilitates the grinding of salt into powder inside the box body. After the marinating product is placed inside the marinating tank body, the operator adds the salt through the inlet and then manually rotates the crank handle, causing the grinding disc to grind the salt into powder under the action of the first and second grinding protrusions. The powder then enters the marinating tank body through the micropores and, with the cooperation of the main shaft and stirring rod, makes uniform contact with the marinating product. This method is simple to operate, improves the uniformity of the salt-marinating product mixture, and is beneficial for food marinating.

[0004] In practice, salt is ground by rotating a grinding disc. However, spices such as pepper and star anise are usually added during the pork curing process to further enhance the curing flavor. But the grinding method using a grinding disc cannot adjust the particle size of the spices and seasonings, making it less practical. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot adjust the particle size of spices and seasonings, and to propose a pickling device for microbial fermentation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a marinating device for microbial fermentation, including a reaction tank, with a cover for closing the feed inlet on the top and inside of the reaction tank, and a stirring mechanism for stirring meat products and spices. A grinding component is arranged above the cover, which is used to grind and sprinkle the spices.

[0008] The grinding assembly includes a first grinding tool and a second grinding tool. The first grinding tool is sleeved around the second grinding tool, and the height between them is adjusted by a locking structure to change the size of the spice grinding particles.

[0009] Furthermore, the grinding assembly also includes a connecting seat and a housing. The connecting seat is fixedly connected to the top of the cover, and the connecting seat communicates with the reaction vessel through a central through hole, and the first grinding tool is fixedly connected within the central through hole.

[0010] Furthermore, the outer shell is rotatably connected to the periphery of the connecting seat, a baffle is fixedly connected inside the outer shell, and a rotating rod is slidably connected to the top center of the outer shell via a limiting part. The bottom end of the rotating rod passes through the baffle and is fixedly connected to the second mold.

[0011] Furthermore, a compression spring is also fitted at the bottom end of the rotating rod, and the two ends of the compression spring abut against the second grinding tool and the baffle, respectively.

[0012] Furthermore, the locking structure includes a support member fixedly connected to the middle of the top of the outer casing, the support member having an opening groove on one side, and an unlocking member that rotates eccentrically on the top of one side, the opening groove containing the rotating rod.

[0013] Furthermore, the support member is rotatably connected to a stop member on one side top. The stop member has an arc-shaped structure and is disposed in the opening groove. The unlocking member rotates to abut against the stop member, thereby driving the stop member to press against the rotating rod.

[0014] The present invention discloses a microbial fermentation pickling device with the following advantages: A grinding assembly is installed on the top cover of the reaction tank. A rotating rod drives a second grinding wheel to rotate, which, in conjunction with the first grinding wheel, grinds and disperses spices and clumps of salt. The ground spices and salt, under the action of the stirring mechanism, can evenly contact the meat products for easy pickling. Furthermore, the height of the rotating rod can be easily adjusted by unlocking and fixing the unlocking mechanism. Changing the height between the second and first grinding wheels allows for adjustment of the particle size of the ground spices, further improving the pickled flavor of the meat products.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A marinating device for microbial fermentation includes a reaction tank 1, a cover 2 for closing the feed inlet is provided on the top and inside of the reaction tank 1, and a stirring mechanism 3 for stirring meat products and spices. A grinding component 4 is provided above the cover 2, and the grinding component 4 is used to grind and sprinkle the spices.

[0023] The grinding assembly 4 includes a first grinding tool 41 and a second grinding tool 42. The first grinding tool 41 is sleeved around the second grinding tool 42, and the height between them is adjusted by a locking structure 5 to change the size of the spice grinding particles.

[0024] Furthermore, the grinding assembly 4 also includes a connecting seat 43 and a housing 44. The connecting seat 43 is fixedly connected to the top of the cover 2. The connecting seat 43 is connected to the reaction vessel 1 through a central through hole, and the first grinding tool 41 is fixedly connected to it within the central through hole.

[0025] Furthermore, the outer shell 44 is rotatably connected to the periphery of the connecting seat 43, and a baffle 441 is fixedly connected inside the outer shell 44. A rotating rod 46 is also slidably connected to the top center of the outer shell 44 through a limiting part 45. The bottom end of the rotating rod 46 passes through the baffle 441 and is fixedly connected to the second mold 42.

[0026] More specifically, a compression spring 47 is also fitted at the bottom end of the rotating rod 46, and the two ends of the compression spring 47 abut against the second grinding tool 42 and the baffle 441 respectively.

[0027] It should be added that the specific structure of the grinding component 4 in this embodiment can be referred to the pepper grinder in the prior art;

[0028] Further, such as Figure 4 As shown in the cross-sectional view, the bottom of the first grinding tool 41 is provided with a conical surface, while the second grinding tool 42 is truncated cone-shaped on the side near the conical surface. The distance between the first grinding tool 41 and the second grinding tool 42 is changed by adjusting the height of the rotating rod 46, thereby changing the size of the spice grinding particles.

[0029] The limiting part 45 includes a limiting groove and a limiting block. The limiting groove is located on the top periphery of the rotating rod 46, and the limiting block is located at the top midpoint of the outer shell part 44. The limiting block is slidably connected to the limiting groove. In this way, the outer shell part 44 and the rotating rod 46 rotate synchronously, preventing the locking structure 5 from loosening when clamping the rotating rod 46.

[0030] In general, the locking structure 5 includes a support member 51 fixedly connected to the middle of the top of the outer shell 44, the support member 51 having an opening slot 511 on one side, and an unlocking member 52 that rotates eccentrically on the top of one side, the opening slot 511 containing the rotating rod 46.

[0031] Finally, the support member 51 is rotatably connected to a stop member 53 on one side top. The stop member 53 has an arc-shaped structure and is disposed in the opening groove 511. The unlocking member 52 drives the stop member 53 to press against the rotating rod 46 by rotating and abutting against the stop member 53.

[0032] In specific operation, due to the eccentric rotation between the unlocking part 52 and the support part 51, the unlocking part 52 is rotated to make it abut against the stop part 53. The stop part 53 is abutted and then rotates to press against the rotating rod 46, thereby achieving the function of adjusting the height of the rotating rod 46.

[0033] Specifically, the top of the outer casing 44 is provided with a feed port, and a handle is fixedly connected to the top of the rotating rod 46.

[0034] Working method: During operation, pork is poured into reaction vessel 1, the cap 2 is fixed with fasteners, spices are poured into connecting seat 43, and the height of the second mold 42 is adjusted according to the required size of spices.

[0035] Rotate the unlocking part 52 to loosen it from the stop part 53. The rotating rod 46 adjusts the distance between the second mold 42 and the first mold 41 by raising and lowering. Then, reverse the unlocking part 52, and the unlocking part 52 presses against the stop part 53. The stop part 53 clamps the rotating rod 46 to fix the height of the second mold 42.

[0036] By rotating the outer casing 44 and the rotating rod 46, the second grinding tool 42, in conjunction with the first grinding tool 41, grinds and sprinkles the spices. The ground spices enter the reaction tank 1, and the stirring mechanism 3 inside the reaction tank 1 stirs the pork.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
