Technical Field
[0001] This utility model relates to the technical field of chestnut processing equipment, and in particular to a steamer for chestnut production and processing. Background Technology
[0002] Chestnut is a deciduous tree belonging to the Fagaceae family, reaching up to 20 meters in height. Its bark is dark gray, rough, and longitudinally fissured. The leaves are elliptical or oblong with irregularly serrated edges, and covered with grayish-white stellate hairs on the underside. It blooms with greenish-yellow flowers in May. It is monoecious, with male inflorescences in erect spikes and female flowers clustered in groups of 3-5 within a spiny involucre (cuculla). Chestnuts are rich in nutrients, including: protein (4.2g / 100g), providing essential nutrition; carotene (190mg / 100g, convertible to vitamin A, beneficial for eyes and skin); minerals (rich in potassium, phosphorus, and magnesium, supporting neuromuscular function and metabolic balance); vitamins (including vitamins C, B1, and B2, enhancing immunity and delaying aging); and dietary fiber (promoting intestinal peristalsis and preventing constipation).
[0003] In the processing of chestnuts, steaming is usually used to better preserve their nutrients. Therefore, a steamer is typically used for processing chestnuts. In existing steamers, chestnuts are usually placed directly into the steamer and steamed. The chestnuts are stacked on top of each other, with small gaps between them, which affects the entry of steam and reduces processing efficiency. Furthermore, during steaming, moisture tends to accumulate in the chestnuts at the bottom of the steamer, affecting the taste of the processed chestnuts. Therefore, a steamer for chestnut production and processing is designed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a steamer for chestnut production and processing.
[0005] The technical problem to be solved by this utility model is to provide a steamer for chestnut production and processing, which solves the problem in the prior art where chestnuts are directly stacked in the steamer during chestnut processing, resulting in small gaps between chestnuts, which affects the entry of steam between chestnuts and reduces the processing efficiency.
[0006] This utility model provides a steamer for chestnut production and processing, including a pot body, a steamer basket, a pot lid and a rack. The steamer basket is detachably snapped onto the top of the pot body. The pot lid is covered on the top of the steamer basket. Multiple racks are welded inside the steamer basket. A circular opening is opened in the center of each rack. A sealing plate is fixedly installed on the circular opening of the bottom rack.
[0007] Preferably, the diameter of the through holes on the grate and the sealing plate is smaller than the diameter of the chestnut to be processed.
[0008] Preferably, the grate is in the shape of an inverted funnel with a higher central horizontal height and a lower surrounding horizontal height.
[0009] Preferably, the distance between two adjacent layers of grates is 4-5 cm, and the diameter of the circular opening is 8-10 cm.
[0010] Preferably, a feed funnel with a larger opening at the top and a smaller opening at the bottom is fixedly installed on the circular opening of the uppermost grate.
[0011] Preferably, a mesh tube passes through the center of the sealing plate, and the mesh tube passes through the circular opening of the upper grate.
[0012] Preferably, the gap between the mesh cylinder and the circular opening is greater than the diameter of the chestnuts after steaming, and the top horizontal height of the mesh cylinder is higher than the bottom horizontal height of the feed funnel.
[0013] Preferably, an annular groove is formed at the bottom of the outer surface of the steamer, and the inner diameter of the annular groove is equal to the inner diameter of the upper opening of the pot body.
[0014] Preferably, the bottom of the pot lid is fixedly provided with an embedded ring, and the outer diameter of the embedded ring is equal to the diameter of the upper opening of the steamer.
[0015] Preferably, pot ears are fixedly provided on the upper left and right sides of the pot body and the steamer, a lifting cap is fixedly provided on the top of the pot lid, and a visible ring-shaped tempered glass window is provided on the pot lid.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] 1. This utility model, by comprising a pot body, a steamer, a pot lid, and a steamer rack, allows for the steaming of chestnuts. Water is added to the pot body, and chestnuts are then added through the circular opening in the center of the steamer rack. Because the steamer rack is shaped like an inverted funnel with a higher central level and lower perimeter, the chestnuts are allowed to fall onto each rack under gravity. The top rack is then covered with chestnuts. The steamer rack is then placed on the pot body, the pot lid is closed, and the water in the pot is heated by a gas stove. The steam cooks the chestnuts. Since the spacing between adjacent racks is 4-5 cm, and the diameter of a chestnut is approximately 3 cm, only one layer of chestnuts can be placed on each rack, preventing chestnut accumulation and ensuring efficient steaming. Furthermore, the inverted funnel shape of the steamer rack prevents moisture accumulation on the rack, ensuring the optimal texture of the steamed chestnuts.
[0018] 2. This utility model features a feeding funnel, which allows chestnuts to be added into the circular opening of the top grate when adding chestnuts to the steamer, making it convenient to add chestnuts and increasing the ease of operation.
[0019] 3. This utility model features a mesh tube, which creates a circular steam channel in the center of the circular opening. When chestnuts are added to the steamer, they are positioned outside the mesh tube at the circular opening, reducing the accumulation of chestnuts at the opening. During the steaming process, steam can circulate through the mesh tube, ensuring efficient steaming of the chestnuts at the circular opening. Attached Figure Description

[0027] Example:
[0028] like Figures 1-4 As shown, an embodiment of this utility model provides a steamer for chestnut production and processing, including a pot body 1, a steamer 2, a pot lid 3, and a rack 4. The steamer 2 is detachably snapped onto the top of the pot body 1, and the pot lid 3 is closed on the top of the steamer 2. Multiple racks 4 are welded inside the steamer 2. A circular opening 401 is opened in the center of the rack 4, and a sealing plate 5 is fixedly installed on the circular opening 401 of the bottom rack 4.
[0029] In this embodiment, the diameter of the through holes on the grate 4 and the sealing plate 5 is smaller than the diameter of the chestnut to be processed, to prevent the chestnut from falling out of the through holes on the grate 4 and the sealing plate 5.
[0030] In this embodiment, the grate 4 is shaped like an inverted funnel with a higher central level and a lower perimeter level, which facilitates the chestnuts entering the top of the grate 4.
[0031] In this embodiment, the distance between two adjacent layers of grates 4 is 4-5cm, and the diameter of the circular opening 401 is 8-10cm, so that the chestnuts can be placed on top of the multi-layer grates 4 through the cylindrical opening 401.
[0032] The steamer is equipped with a pot body 1, a steamer basket 2, a pot lid 3, and steaming racks 4. When steaming chestnuts, water is added to the pot body 1, and then the chestnuts are added through the central circular opening 401 of the steaming racks 4. Because the steaming racks are shaped like an inverted funnel with a higher central level and lower perimeter, the chestnuts are allowed to fall onto each layer of racks 4 under gravity. The top rack 4 is then covered with chestnuts. The steamer basket 2 is then placed on the pot body 1, and the pot lid 3 is closed. The water in the pot 1 is heated by a gas stove, and the steam cooks the chestnuts. Since the distance between two adjacent racks is 4-5cm, and the diameter of a chestnut is about 3cm, only one layer of chestnuts can be placed on top of each rack 4 to prevent the chestnuts from piling up and to ensure the steaming efficiency of the steamer. In addition, the rack 4 is shaped like an inverted funnel with a higher horizontal height in the center and a lower horizontal height around the edges, which can prevent water from accumulating on the rack 4 and ensure the taste of the chestnuts after steaming.
[0033] In this embodiment, a feeding funnel 6 with a larger upper opening and a smaller lower opening is fixedly installed on the circular opening 401 of the upper grate 4.
[0034] With the addition of a feeding funnel 6, chestnuts are added to the top rack through the feeding funnel 6 into the circular opening 401, making it easier to add chestnuts and increasing the convenience of operation.
[0035] In this embodiment, a mesh cylinder 7 is inserted through the center of the sealing plate 5. The mesh cylinder 7 passes through the circular opening 401 of the upper grate 4. The mesh cylinder 7 allows the chestnuts at the circular opening 401 to have a steam flow channel, which facilitates the flow of steam from the mesh cylinder 7, reduces the accumulation of chestnuts at the circular opening 401, and increases the steaming efficiency of chestnuts at the circular opening 401.
[0036] In this embodiment, the gap between the mesh cylinder 7 and the circular opening 401 is larger than the diameter of the chestnuts after steaming, so that the chestnuts can be added through the gap between the circular opening 401 and the mesh cylinder 7. The top horizontal height of the mesh cylinder 7 is higher than the bottom horizontal height of the feeding funnel 6 to prevent the chestnuts from entering from the top opening of the mesh cylinder 7.
[0037] By setting up a mesh cylinder 7, a circular steam channel can be generated in the center of the circular opening 401. After the chestnuts are added into the steamer 2, the chestnuts at the circular opening 401 are located on the outside of the mesh cylinder 7, reducing the accumulation of chestnuts at the circular opening 401. When the chestnuts are steamed, the steam can flow through the mesh cylinder 7, ensuring the steaming efficiency of the chestnuts at the circular opening 401.
[0038] In this embodiment, an annular groove 201 is provided at the bottom of the outer surface of the steamer 2, and the inner diameter of the annular groove 201 is equal to the inner diameter of the upper opening of the pot body 1. When the steamer 2 is placed into the pot body 1, it is engaged in the pot body 1 through the annular groove 201, thereby realizing the connection between the pot body 1 and the steamer 2 and ensuring the tightness of the connection.
[0039] In this embodiment, an embedded ring 301 is fixedly provided at the bottom of the pot lid 3, and the outer diameter of the embedded ring 301 is equal to the diameter of the upper opening of the steamer 2. When the pot lid 3 is placed on top of the steamer 2, the embedded ring 301 is embedded in the upper opening of the steamer 2, ensuring the sealing state when the pot lid 3 is placed on the steamer 2.
[0040] In this embodiment, pot ears are fixedly provided on the upper left and right sides of the pot body 1 and the steamer 2, so as to facilitate the removal of the pot body 1 and the steamer 2 through the pot ears. A lifting cap is fixedly provided on the top of the pot lid 3, so as to facilitate the removal of the pot lid 3 through the lifting cap. A viewing ring tempered glass window is provided on the pot lid 3, so as to facilitate the observation of the steaming status of the chestnuts in the pot body 1.
