Description

Technical Field

[0001] The utility model belongs to the technical field of food pickling, in particular to a grass silkworm pickling device. Background Art

[0002] Grass silkworms (also known as ground ring, nectar, and cordyceps) are a common edible plant, particularly popular in parts of Asia. They not only have a unique flavor but also possess significant nutritional value. Pickling grass silkworms is a traditional food preservation method that extends their shelf life and imparts a unique flavor. Salt water or acetic acid is typically used in jars, vats, or tanks to inhibit microbial growth and maintain freshness. During the pickling process, the grass silkworms are typically cleaned and then immersed in a container containing a high-concentration salt solution or acetic acid for a specified period of time. For example, the Chinese utility model patent "A Kimchi Pickling Pool" with publication number CN206371451U specifically discloses a kimchi pickling pool, including a pool body and a pool cover. The inner wall of the pool body is coated with a waterproof layer, and the surface of the waterproof layer is coated with a food-grade epoxy resin paint layer. The pool body is filled with vegetables to be pickled, and the surface of the vegetables is covered with a salt sealing layer, and the surface of the salt sealing layer is covered with a PE film; a groove portion is provided at the edge of the mouth of the pool body, a protrusion is provided on the lower end face of the pool cover, and a rubber pressing portion is provided on the surface of the protrusion, the edge of the PE film extends out of the pool body, the pool cover is inserted into the groove portion of the pool body through the protrusion, and the rubber pressing portion presses the PE film into the groove portion; a number of transparent organic glass plate fan-shaped blocks are inlaid in the pool cover, and a fan-shaped shield corresponding to the transparent organic glass plate fan-shaped blocks is provided on the upper surface of the pool cover. A fan-shaped cover for accommodating the fan-shaped shield is also provided on the pool cover, and the fan-shaped shield and the fan cover are connected in a coaxial rotation manner. The pickle pickling pool of the utility model adopts the salt sealing layer as a seal, so that the pickled pickles have a better taste.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figure 1 and Figure 3 As shown, the present application provides a grass silkworm pickling device, including a pickling pool 2, a filter basket 4 and a stirring member, a base 1 is provided under the pickling pool 2, and the upper end cover of the pickling pool 2 is provided with a sealing cover 10; the filter basket 4 is annular in shape and is vertically placed at the bottom of the pickling pool 2; the stirring member is provided on the upper side of the sealing cover 10 and is located directly above the filter basket 4, one end of the stirring member passes through the sealing cover 10 and extends into the central area of the filter basket 4, and extends to the bottom of the pickling pool 2, and the stirring member is used to stir the pickling liquid.

[0022] Specifically, the curing tank 2 forms the main structure of the entire apparatus and is constructed of bricks and cement. To prevent corrosion from the curing liquid (which typically contains high concentrations of salt or acidic components), the interior of the tank 2 is paved with acid- and alkali-resistant ceramic tiles. These tiles offer high chemical resistance and effectively protect the interior of the tank 2 from the corrosive effects of the curing liquid. A base 1 is located beneath the tank 2, connected to the tank 2 by welding or other fastening methods, providing stable support. A sealing cover 10 is located at the top of the tank 2. This cover 10 is tightly secured to the tank 2 via threads, snaps, or other means, ensuring a sealed environment. A handle is provided on the sealing cover 10, making it easier for operators to open and close it. A filter basket 4 is placed vertically directly on the inner bottom of the tank 2 and can be easily lifted out of the tank 2 if needed. The filter basket 4 is designed as an annular structure, primarily consisting of an annular base, an outer annular wall, and an inner annular wall. The annular base, located at the bottom of the filter basket 4, is a flat, annular bottom surface with a mesh design featuring small holes to facilitate the infiltration and outflow of the pickling liquid. The outer annular wall, perpendicularly connected to the outer edge of the annular base, serves as the primary load-bearing component of the filter basket 4 and is constructed from a continuous loop of mesh or wire. The thickness and strength of the outer annular wall determine the load-bearing capacity and durability of the filter basket 4. The inner annular wall, perpendicularly connected to the inner edge of the annular base and parallel to it, is also constructed from mesh or wire. The annular base, outer annular wall, and inner annular wall together form a storage area for pickling materials such as grass silkworms. The inner annular wall extends from the center to the center of the filter basket 4, forming a continuous flow path for the pickling liquid. The top edge of the outer annular wall is thickened or reinforced and equipped with a handle to facilitate lifting the filter basket 4. The mesh size design on the filter basket 4 can ensure the smooth flow of pickling liquid and particulate matter, and can prevent pickled products such as grass silkworms from falling through the mesh. The filter basket 4 is made of corrosion-resistant materials, such as stainless steel, to ensure that it is not easy to rust or corrode in the pickling environment. One end of the stirring element remains outside the sealing cover 10 and is connected to the drive mechanism to provide rotational power, and the other end passes through the sealing cover 10 through the shaft hole or bearing, enters the central area of the filter basket 4, and extends to the bottom of the pickling tank 2. When the stirring element stirs the pickling liquid in the central area of the filter basket, it will not directly contact the grass silkworms in the storage area, effectively protecting the grass silkworms from damage. The stirring element is a long rod-shaped structure, one end of which is designed to be suitable for stirring, such as a propeller shape, a blade shape, etc., and the other end is the power transmission part, which will be connected to a motor or other type of drive unit.

[0023] The above technical solution adopted by the grass silkworm pickling device provided in this application can achieve the following beneficial effects:

[0024] By designing the filter basket 4 within the curing tank 2 into an annular structure, with one end of the stirring element extending through the sealing cover 10 into the center of the filter basket 4 and to the bottom of the curing tank 2, the curing liquid at different depths within the curing tank 2 can be fully stirred, ensuring uniform mixing of the curing liquid at all levels. This eliminates the problem of concentration differences between upper and lower layers due to gravity, ensuring the quality and taste of the pickled grass silkworms. During the stirring process, the stirring element does not come into direct contact with the grass silkworms in the storage area, effectively protecting them from damage. Furthermore, the design of the sealing cover 10 ensures a tight seal during the curing process, preventing external impurities from entering the curing tank 2, while also reducing evaporation of the curing liquid and maintaining a stable curing environment.

[0025] In one embodiment, the stirring member includes a motor 11 and a stirring shaft 5. The motor 11 is installed on the upper side of the sealing cover 10. One end of the stirring shaft 5 is connected to the output end of the motor 11, and the other end passes through the sealing cover 10 and extends into the central area of the filter basket 4 and extends to the bottom of the pickling tank 2. Several groups of stirring blades 6 are provided on the stirring shaft 5, and the several groups of stirring blades 6 are equidistantly distributed along the axial direction of the stirring shaft 5.

[0026] Specifically, the stirring member includes two major parts: a motor 11 and a stirring shaft 5. The motor 11 is installed on the upper side of the sealing cover 10 to provide a power source for the stirring action. One end of the stirring shaft 5 is firmly connected to the output end of the motor 11 to receive the rotational force from the motor 11; the other end passes through the sealing cover 10, extends into the central area of the filter basket 4, and further extends to the bottom of the pickling pool 2, ensuring that the stirring range covers all depths of the entire pickling pool 2. Several groups of stirring blades 6 are provided on the stirring shaft 5, and these stirring blades 6 are distributed at equal distances along the length direction of the stirring shaft 5 to ensure that the pickling liquid can be evenly mixed during the stirring process, so that the grass silkworm can be evenly affected by the pickling liquid during the pickling process. Such a design not only improves the uniformity of pickling, but also helps to improve the pickling efficiency.

[0027] Based on the above embodiment, the stirring blades 6 form an angle of 30° to 75° with the stirring shaft 5 , and each group of stirring blades 6 is provided with at least two stirring blades, which are arranged in a ring around the stirring shaft 5 to form an inverted umbrella shape.

[0028] Specifically, the angle formed by the stirring blades 6 and the stirring shaft 5 is between 30° and 75°, and each group of stirring blades 6 has at least two stirring blades 6. For example, the angle between each stirring blade 6 and the stirring shaft 5 is 45°. Three stirring blades 6 are provided in each group, and these stirring blades 6 are arranged in a ring around the stirring shaft 5, together forming an inverted umbrella-shaped structure. Due to the specific angle formed between the stirring blades 6 and the stirring shaft 5, when the stirring shaft 5 rotates, the stirring blades 6 can better promote the flow of the pickling liquid, forming a strong turbulent effect, so that the pickling liquid is more evenly distributed in the pool, thereby improving the uniformity of pickling. The inverted umbrella-shaped design enables the stirring blades 6 to effectively push the pickling liquid at the bottom upward when rotating, and at the same time pull the liquid on the surface downward, thereby promoting the vertical circulation of the liquid in the pickling pool 2, and ensuring that the grass silkworms can be evenly exposed to the pickling liquid at all levels.

[0029] Furthermore, it also includes a pickling liquid circulation mechanism, which includes a supporting mesh plate 3 and a circulation component. The supporting mesh plate 3 is horizontally arranged inside the pickling pool 2, and is supported and connected to the pickling pool 2, and a avoidance opening equal to the cross-section of the central area of the filter basket 4 is opened at its center position. The supporting mesh plate 3 and the bottom of the pickling pool 2 form a first area 18, and form a second area 12 for holding grass silkworms with the upper part of the pickling pool 2. The filter basket 4 is placed on the supporting mesh plate 3, and the stirring shaft 5 can pass through the avoidance opening and extend into the first area 18. The circulation component is arranged outside the pickling pool 2, with one end penetrating the wall of the pickling pool 2 and extending into the first area 18, and the other end penetrating the wall of the pickling pool 2 and extending into the top of the second area 12.

[0030] Specifically, the grass silkworm curing device also includes a curing liquid circulation mechanism, primarily consisting of a support mesh 3 and a circulation assembly. The support mesh 3 is horizontally positioned within the curing tank 2 and is connected to the tank's structural support. Specifically, the support mesh 3 rests on a raised platform on the inner wall of the tank 2, serving to partition the space within the tank 2. A clearance opening is defined at the center of the support mesh 3. The cross-sectional area of this clearance opening is equal to that of the center of the filter basket 4, allowing the stirring shaft 5 to pass smoothly through and into the first region 18 of the curing tank 2 (the space formed by the support mesh 3 and the bottom of the tank 2 is referred to as the first region 18). Above the support mesh 3 is formed a second region 12 for holding the grass silkworms. The filter basket 4 is placed on the support mesh 3 to ensure that the grass silkworms are evenly immersed during the curing process. The mesh size design of the support mesh 3 ensures smooth circulation of the curing liquid and particulate matter while preventing the curing products, such as the grass silkworms, from falling through the mesh. A circulation assembly is located outside the curing tank 2 and is responsible for promoting the circulation of the curing liquid within the tank 2. One end of the circulation assembly extends through the wall of the tank 2 into the first region 18, directly contacting the curing liquid within the first region 18. The other end penetrates the wall of the tank 2 and extends above the second region 12, ensuring that the curing liquid drawn from the first region 18 can be directly sprayed onto the grass silkworms in the second region 12, thereby promoting uniform distribution of the curing liquid throughout the tank 2.

[0031] Based on the above scheme, the circulation component includes a discharge pipe 17, a booster pump 16, a delivery pipe 8 and several spray heads 7. One end of the discharge pipe 17 passes through the wall of the pickling pool 2 and extends into the first area 18, and the other end is connected to the water inlet end of the booster pump 16 arranged on the outer wall of the pickling pool 2. The water outlet end of the booster pump 16 is connected to the water inlet end of the delivery pipe 8. The water outlet end of the delivery pipe 8 passes through the wall of the pickling pool 2 and extends above the filter basket 4. Several spray heads 7 are arranged on the delivery pipe 8.

[0032] Specifically, the circulation assembly includes a discharge pipe 17, a booster pump 16, a delivery pipe 8, and several spray heads 7. One end of the discharge pipe 17 penetrates the wall of the curing tank 2 and extends into the first area 18 below the support mesh 3. The discharge pipe 17 is designed to extract curing liquid from the first area 18, ensuring that the extracted curing liquid originates from the bottom area of the curing tank 2. The booster pump 16 is mounted on the outer wall of the curing tank 2, and the other end of the discharge pipe 17 is connected to the water inlet of the booster pump 16. The booster pump 16 is the power source for the circulation assembly, responsible for pumping the curing liquid from the first area 18 and delivering it under pressure to the delivery pipe 8. One end of the delivery pipe 8 is connected to the water outlet of the booster pump 16 to receive the curing liquid delivered by the booster pump 16. The other end of the delivery pipe 8 penetrates the wall of the curing tank 2 and extends into the second area 12 above the filter basket 4. The design of the delivery pipe 8 allows the curing liquid to be sprayed from above the second area 12 onto the grass silkworms placed in the filter basket 4. Several spray heads 7 are evenly distributed along the delivery pipe 8, evenly spraying the curing liquid delivered from the delivery pipe 8 onto the grass silkworms in the filter basket 4. This increases the contact area between the curing liquid and the grass silkworms and improves the curing effect. The circulation assembly effectively promotes the circulation of the curing liquid within the curing tank 2. First, the discharge pipe 17 draws the curing liquid from the first area 18 at the bottom of the curing tank 2. The liquid is then pressurized by the booster pump 16 and returned through the delivery pipe 8 to above the second area 12 of the curing tank 2. Finally, the spray heads 7 evenly spray the curing liquid onto the grass silkworms. This circulation not only ensures uniform distribution of the curing liquid but also improves the efficiency and quality of curing, ensuring that the grass silkworms evenly absorb the flavor of the curing liquid during the curing process.

[0033] In one embodiment, a lifting mechanism is further included, which includes a telescopic rod 14 and a cross bar 13. One end of the telescopic rod 14 is connected to the base 1, and the other end is connected to the cross bar 13. One end of the cross bar 13 extends horizontally to just above the pickling pool 2, and a hook 9 is provided on it. The hook 9 can be hung and connected with the filter basket 4, and the telescopic rod 14 can drive the filter basket 4 to rise and fall.

[0034] Specifically, the lifting mechanism comprises a telescopic rod 14 and a crossbar 13. One end of the telescopic rod 14 is fixedly connected to the base 1 below the pickling tank 2, serving as the lifting mechanism's support point. The other end is connected to the crossbar 13, and the telescopic movement of the telescopic rod 14 drives the crossbar 13 up and down. The telescopic rod 14 can be hydraulically, pneumatically, or electrically operated to facilitate automated control. One end of the crossbar 13 extends horizontally directly above the pickling tank 2, serving as a support structure for suspending the filter basket 4. Hooks 9 are provided on the crossbar 13, located at either end or in the middle of the crossbar 13 to ensure even suspension of the filter basket 4. The position of the hooks 9 should take into account the center of gravity of the filter basket 4 to maintain balance during suspension. The hooks 9 are designed as metal pieces with a certain degree of curvature and can be U-shaped, S-shaped, or other suitable designs. The opening size of the hooks 9 must match the size of the hanging ears or rings of the filter basket 4 to ensure smooth attachment. The hook 9 is made of high-strength metal, such as stainless steel or galvanized steel, to ensure durability and corrosion resistance. This material not only supports the weight of the filter basket 4 and its contents, but also withstands the potential chemical corrosion present in the pickling environment. The hook 9 is connected to the filter basket 4 via lugs or loops on the filter basket 4. These lugs or loops are designed to be fixed, ensuring quick and accurate connection to the hook 9 when hanging and easy removal when needed. The coordinated design of the hook 9 and the filter basket 4 prevents the filter basket 4 from falling during lifting or lowering, while also facilitating loading and unloading operations. A telescopic rod 14 drives the filter basket 4 upwards and downwards. To lift the filter basket 4 from the pickling tank 2, the telescopic rod 14 extends, driving the crossbar 13 and the filter basket 4 on it upwards. Conversely, to place the filter basket 4 into the pickling tank 2, the telescopic rod 14 reverses, lowering the filter basket 4 to a desired position within the tank 2.

[0035] Based on the above embodiment, a guide rod 15 is provided at the end of the cross bar 13 away from the hook 9, and the guide rod 15 is arranged vertically. A slide groove 141 is provided on the cylindrical surface of the end of the telescopic rod 14 away from the cross bar 13, and the slide groove 141 includes a vertical guide groove 1412 and a curved guide groove 1411. A guide column 151 is provided at the end of the guide rod 15 away from the cross bar 13, and the guide column 151 is slidably connected to the slide groove 141. The telescopic rod 14 can drive the filter basket 4 to rise and fall and rotate.

[0036] Specifically, the guide rod 15 is vertically positioned at the end of the crossbar 13 away from the hook 9, forming a "7" shape with the crossbar 13. This design not only ensures stable guidance and support for the crossbar 13 during horizontal extension, but also enhances the stability of the entire lifting mechanism. The guide rod 15 is a rod-shaped structure, primarily functioning to maintain the linear motion of the crossbar 13 during its raising and lowering, while also driving the crossbar 13 in rotation. A chute 141 is defined on the end of the telescopic rod 14 away from the crossbar 13, i.e., the unextended portion of the telescopic rod 14. This chute 141 extends vertically along the telescopic rod 14 and consists of a vertical guide groove 1412 and a curved guide groove 1411. The vertical guide groove 1412 is located at the lower portion of the telescopic rod 14 and is designed to be long enough to ensure that the crossbar 13 can lift the filter basket 4 out of the pickling tank 2. The curved guide groove 1411 is positioned above and connected to the vertical guide groove 1412, creating a smooth transition to ensure that the guide post 151 does not get stuck or encounter resistance during sliding. The curved angle of guide groove 1411 enables crossbar 13 to guide filter basket 4 away from the top of pickling tank 2 to a convenient location. Guide post 151 is located at the end of guide rod 15 away from crossbar 13 and is slidable within chute 141. The shape of guide post 151 matches that of chute 141, ensuring smooth sliding within chute 141 without deviating from its track.

[0037] When telescopic rod 14 drives crossbar 13 upward, crossbar 13 drives filter basket 4 upward, and guide rod 15 also rises with crossbar 13. During this process, guide post 151 slides within vertical guide slot 1412, ensuring that crossbar 13 and guide rod 15 maintain vertical linear motion, allowing filter basket 4 to rise smoothly. When guide post 151 enters curved guide slot 1411 and continues to slide, it begins to drive the vertical rod upward while rotating. As guide post 151 slides within curved guide slot 1411, the vertical rod rises and rotates along a curved path. The rotation of the vertical rod drives crossbar 13 to rotate, which in turn causes crossbar 13 to drive the filter basket 4 to rotate simultaneously during the ascent.

[0038] In one embodiment, a drain port is provided at the bottom of the pickling tank 2 .

[0039] Specifically, a drain port is provided at the bottom of the curing tank 2, primarily for draining the curing liquid or cleaning fluid within the tank 2. The drain port is located at the bottom of the tank 2 because during the curing or cleaning process, a large amount of curing liquid or cleaning wastewater, as well as any sediment or impurities, often accumulates at the bottom. Positioning the drain port at the lowest point ensures that the liquid and impurities are drained as completely as possible. The drain port's primary function is to drain the curing liquid. After curing is complete, the drain port can be opened to drain the curing liquid for further processing or replacement. Furthermore, when cleaning the tank 2, the drain port can also be used to drain cleaning wastewater, streamlining the cleaning process. The drain port is equipped with a valve or similar device to facilitate control of the drainage process. The valve can be manually operated or, if desired, electrically or pneumatically operated for automated control. When closed, the valve should be tightly sealed to prevent leakage during the curing process. The design of the drain port also needs to take into account the convenience of daily maintenance, such as regularly cleaning the sediment around the drain port, checking whether the valve is intact, and ensuring that the drain channel is unobstructed.

[0040] The specific working process is as follows:

[0041] When curing grass silkworms, the selected and cleaned grass silkworms are first placed in a filter basket 4, which is then hung from a crossbar 13 via a hook 9. Using a telescopic rod 14, the filter basket 4 is lowered into the curing tank 2, ensuring it rests on the support mesh 3. The prepared curing liquid is then poured into the curing tank 2, and the sealing cover 10 is closed over the top of the tank 2. During the curing process, the curing liquid is periodically stirred or circulated. During the stirring process, the motor 11 is activated, driving the stirring shaft 5 to rotate. The stirring blades 6 on the stirring shaft 5 uniformly mix the curing liquid. To maintain circulation, the booster pump 16 is activated, and the discharge pipe 17 draws the curing liquid from the first region 18 at the bottom of the curing tank 2. The booster pump 16 pressurizes the extracted curing liquid and returns it to the top of the second region 12 of the curing tank 2 through the delivery pipe 8. The spray head 7 on the delivery pipe 8 sprays the pressurized pickling liquid evenly onto the grass silkworms in the filter basket 4.

[0042] After the grass silkworms are pickled, when the filter basket 4 needs to be lifted out of the pickling tank 2, hook the hook 9 onto the handle of the sealing cover 10, activate the telescopic rod 14, and move the sealing cover 10 and the stirring element together to the appropriate position. After the sealing cover 10 is removed, begin lifting the filter basket 4. First, hook the hook 9 onto the hanging ear or ring of the filter basket 4 and activate the telescopic rod 14 to extend, driving the crossbar 13 and the filter basket 4 on it to rise. During this process, the guide post 151 slides within the vertical guide slot 1412, ensuring that the crossbar 13 and guide rod 15 maintain vertical linear motion, allowing the filter basket 4 to rise smoothly vertically. When the guide post 151 enters the curved guide slot 1411 and continues to slide, the vertical rod rises and rotates along the curved path, driving the crossbar 13 to rotate, which in turn causes the filter basket 4 to rotate simultaneously during the ascent, moving the filter basket 4 to a position that is easy to operate. After removing the filter basket 4, when draining the curing liquid, open the valve on the drain port and drain the curing liquid through the drain port to ensure complete drainage of the liquid within the curing tank 2. After draining, the curing tank 2 can be cleaned to ensure a clean and sanitary interior before the next curing session. During the cleaning process, the circulation assembly can be reused to pump the cleaning liquid through the drain pipe 17, pressurize it with the booster pump 16, and spray it through the spray head 7 to thoroughly clean the curing tank 2.
