Abstract
Description
Technical Field
[0001] This utility model relates to the field of blanching equipment technology, and more specifically, to a blanching equipment combining steam drum and blanching. Background Technology
[0002] Agricultural products refer to various primary products and products that have undergone simple processing obtained in the process of agricultural production, covering plants, animals and their by-products, including grains (rice, wheat, corn, etc.), vegetables (cabbage, tomatoes, potatoes, etc.), fruits (apples, bananas, citrus, etc.), tea, oil crops (peanuts, rapeseed, etc.), Chinese medicinal herbs, cotton, hemp, etc.
[0003] Blanching is a key process in the processing of agricultural products (especially plant-based products) that uses high temperatures to quickly destroy the activity of enzymes (such as polyphenol oxidase and peroxidase) in fresh products to prevent oxidation and deterioration (such as browning and flavor loss). At the same time, it removes some moisture and softens the tissue to facilitate subsequent processing (such as rolling, drying, and storage). It is commonly used in the processing of tea, vegetables, and Chinese medicinal herbs.
[0004] Among them, the patent with announcement number CN221307071U discloses a tea fixing machine, which belongs to the field of tea processing equipment technology. Through the combined action of the box, drum, water tank and heating plate, and with multiple filter holes opened on the drum, steam is used to enter the drum through the filter holes to fix the tea.
[0005] When in use, this structure works by combining the drive assembly, the drum, and the stirring assembly. The drive assembly can drive the drum and the stirring assembly to rotate in the opposite direction to stir the tea leaves, allowing them to tumble evenly and further improving the withering effect. However, the stirring rod can easily squeeze the tea leaves during stirring, which can cause damage and affect the quality of the withering process. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steam drum combined with blanching equipment, which aims to solve the problems mentioned in the background art.
[0007] This utility model provides the following technical solution: a steam drum combined with blanching equipment, including an outer cylinder, on which a material-gathering blanching component is provided;
[0008] The material-gathering blanching assembly includes a material-gathering disc disposed at the bottom of the outer cylinder, a discharge chamber formed between the outer cylinder and the material-gathering disc, a steam gathering hood for conveying steam disposed on the material-gathering disc, a pad disposed on the top of the steam gathering hood, and a plurality of filter elements disposed on the pad, each penetrating the pad and connected to the steam gathering hood.
[0009] Each of the filter elements is provided with a feeding disc at its top, and the feeding disc has several feeding ports through it.
[0010] Optionally, in a possible implementation, electric heating plates are respectively provided on both sides of the steam gathering hood, and a screening rod is respectively provided on one side of each electric heating plate. The cross-sectional shape of the two screening rods is set to arc shape, and the screening rods extend to the outside of the steam gathering hood and are slidably connected to the steam gathering hood. The electric heating plates are installed on the inner wall of the outer cylinder by bolts, and screening holes are opened through both ends of each screening rod. The vertical cross-sectional shape of the steam gathering hood is set to frustum shape, and a retaining ring is provided on the outside of the gathering plate. A motor for driving the feeding plate to rotate is provided at the top of the outer cylinder, and a feeding pipe for feeding is provided on one side of the motor. The feeding pipe passes through the outer cylinder and extends to the top of the feeding plate.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] By using an arc-shaped sieve rod in conjunction with the rotating motion of the feeding disc, the agricultural products are evenly distributed through flexible tumbling, avoiding mechanical damage caused by rigid contact. The sieve rod is slidably connected to the steam gathering hood, and its arc-shaped structure can conform to the movement trajectory of the agricultural products, reducing tearing, and is especially suitable for the blanching process of delicate raw materials such as tender leaves and tea buds.
[0013] The steam-gathering hood provides steam for blanching, and the high-temperature heating of the electric heating plate creates a three-dimensional heating environment. The steam is evenly diffused after being filtered by the filter element. Combined with the auxiliary heating of the electric heating plate, it ensures that the agricultural products are heated evenly and shortens the blanching time. The frustum-shaped steam-gathering hood can efficiently gather steam and reduce heat loss. The filter element can not only filter out excess moisture in the steam, but also disperse the steam to multiple points, so that the agricultural products can fully contact the steam during the falling process and improve the consistency of blanching.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This embodiment discloses a steam drum combined with a withering device, and the agricultural product targeted in this embodiment is preferably tea. It aims to solve the problem in the prior art where tea leaves are damaged and have poor forming quality due to the squeezing of the stirring rod during withering. By employing a combination of uniform steam penetration and gentle turning, efficient withering of tea leaves is achieved while reducing damage.
[0023] like Figure 1 As shown, it includes an outer cylinder 1, which is a cylindrical stainless steel shell. A motor 11 is fixed to the top of the outer cylinder 1 by bolts, and a material collection tray 2 is welded to the bottom. An annular discharge chamber is formed between the outer cylinder 1 and the material collection tray 2 for discharging the tea leaves after the tea leaves have been processed. A retaining ring is welded to the outside of the material collection tray 2 to prevent the tea leaves from leaking out from the edge.
[0024] like Figure 2 , Figure 5 As shown, a steam gathering cover 3 is fixed to the center of the material gathering tray 2 by bolts. Its vertical cross section is frustum-shaped and hollow inside to gather steam, making it convenient to gather the steam delivered by the external steam generator together.
[0025] like Figure 3 , Figure 5 As shown, a circular pad 4 is connected to the top of the steam gathering hood 3 via a flange. Several filter elements 5 are installed on the pad 4. The lower end of the filter elements 5 is connected to the inside of the steam gathering hood 3, so as to transport the steam inside the steam gathering hood 3 to the outer cylinder 1. The filter elements 5 can also filter out a lot of moisture.
[0026] like Figure 3 As shown, multiple filter elements 5 are welded together at their top ends with a feeding disc 6. The feeding disc 6 has several feeding ports 7. The center of the feeding disc 6 is connected to the output shaft of the motor 11 via a coupling.
[0027] Motor 11 can be a three-phase asynchronous motor of model Y2-132M-4, which is fixed on the top support of the outer cylinder 1. Its function is to drive the feed plate 6 to rotate at a uniform speed so that the tea leaves are evenly distributed to each feed port 7.
[0028] like Figure 1 , Figure 2 As shown, a feed pipe 12 is provided on the left side of the motor 11, which extends through the top of the outer cylinder 1 to the top of the feed plate 6, and is used to transport the tea leaves to be processed to the feed plate 6.
[0029] like Figure 2 , Figure 3 , Figure 4 As shown, electric heating plates 8 are symmetrically arranged on both sides of the steam gathering hood 3. Each electric heating plate 8 is provided with a sieve rod 9 on one side. The sieve rod 9 extends to the outside of the steam gathering hood 3 and is slidably connected to the hood body. Sieve holes 10 are opened at both ends for the feeding plate 6 and the filter element 5 to rotate to facilitate turning the tea leaves and screening impurities. The sieve holes 10 also facilitate the tea leaves after the fixation process to enter the discharge chamber.
[0030] The specific working principle is as follows: agricultural products such as tea leaves to be processed are conveyed through the feed pipe 12 to the upper part of the feed plate 6 inside the outer cylinder 1. At this time, the motor 11 is started, and the motor 11 drives the feed plate 6 to rotate at a constant speed, so that the tea leaves are evenly distributed under the action of centrifugal force and fall through the feed port 7 on the feed plate 6.
[0031] The falling tea leaves will come into contact with the filter element 5, while the steam supplied by the external steam generator enters the steam gathering hood 3. Because the vertical cross section of the steam gathering hood 3 is truncated cone-shaped, it can effectively gather the steam. After the steam passes through the filter element 5 to remove excess moisture, it diffuses upward and comes into full contact with the falling tea leaves, thus initially achieving steam fixation.
[0032] During the fixation process, the electric heating plates 8 on both sides of the steam gathering hood 3 are energized and heated, raising the internal temperature of the outer cylinder 1. This, combined with the steam, creates a dual heating environment, enhancing the fixation effect. At the same time, the feeding disc 6 rotates, causing the filter element 5 to rotate synchronously. This causes the sieve rod 9 to slide along the outside of the steam gathering hood 3. The arc-shaped sieve rod 9 gently turns the tea leaves, avoiding the squeezing and damage caused by traditional stirring rods. During the turning process, impurities can be initially screened and separated through the sieve holes 10 at both ends of the sieve rod 9.
[0033] After the tea leaves have been processed, they are pushed by gravity and the sieve rod 9 through the sieve hole 10 into the discharge chamber between the outer cylinder 1 and the collecting plate 2. Finally, they are discharged from the bottom of the equipment along the discharge chamber. The baffle ring on the outside of the collecting plate 2 can prevent the tea leaves from leaking out from the edge, ensuring the complete collection of the tea leaves after processing.
[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
