Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigar tobacco fermentation technology, and in particular to a cigar tobacco rehumidification and fermentation device. Background Technology
[0002] The reason for fermenting cigar tobacco leaves is to obtain a better taste. Cigar tobacco leaf fermentation is mainly divided into two categories: natural fermentation and artificial fermentation. Natural fermentation is carried out by taking advantage of changes in natural climate, but the natural fermentation cycle is long and has high requirements for the natural environment of the fermentation site, especially temperature and humidity. Artificial fermentation is mainly carried out in a fermentation room.
[0003] A search revealed that patent CN116725224A discloses a cigar tobacco fermentation device.
[0004] However, the above technical solution has the following problems: when the cigar tobacco leaves are rehydrated inside the equipment, the dust on their surface is not easily absorbed by the vacuum cleaner, so that there is still dust or impurities in the cigar tobacco leaves inside the equipment, which in turn affects the quality of the cigar tobacco leaves. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where, during the rehumidification process of cigar tobacco leaves inside the equipment, the dust on the surface of the tobacco leaves is not easily absorbed by the vacuum cleaner, resulting in dust or impurities remaining in the cigar tobacco leaves inside the equipment, which in turn affects the quality of the cigar tobacco leaves. Therefore, this invention proposes a cigar tobacco leaf rehumidification and fermentation device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cigar tobacco rehumidification and fermentation device includes a tank body, a controller with a display on one side of the tank body, a lid on the top of the tank body, a temperature sensor and a humidity sensor on the lid, a heating tube on the tank body, a No. 1 motor fixedly mounted on the lid, the output shaft of the No. 1 motor rotating through the top of the lid and extending into the interior of the tank body, a flipping mechanism fixedly connected to the output shaft of the No. 1 motor, a feeding pipe on the lid, a humidification pipe on the top of the lid, and a spray head fixedly connected to the bottom end of the humidification pipe through the top of the lid.
[0008] The pretreatment unit is installed on the feeding pipe and is used to remove dust from the tobacco leaves.
[0009] In one possible design, the pretreatment mechanism includes a pretreatment channel, a vacuum cleaner, a first side plate, a second side plate, a second motor, a perforated plate, a reciprocating lead screw, a first connecting frame, a U-shaped frame, four sliding rods, four second connecting frames, and four base plates. The pretreatment channel is inclinedly arranged and connected to the feeding pipe. A hole is formed at the bottom of the pretreatment channel. The two sides of the perforated plate are slidably connected to the inner walls of the same pretreatment channel. The adjacent sides of the first and second side plates are fixedly connected to the two sides of the same pretreatment channel. The tops of the four sliding rods are fixedly connected to the bottom sides of the first and second side plates, respectively. The tops of the four base plates are fixedly connected to the bottoms of the four sliding rods. The bottom of the second motor is fixedly connected to the center of the top of the second side plate by bolts. The output shaft of the second motor rotates through the top of the second side plate and is fixedly connected to one end of the reciprocating lead screw. One end of the reciprocating lead screw is rotatably connected to the bottom center of the second side plate. Both ends of the top of the U-shaped frame are fixedly connected to the bottom of the same second side plate. The other end of the reciprocating lead screw is rotatably connected to the inner wall of the U-shaped frame. One end of the first connecting bracket is threaded onto the reciprocating lead screw. The other end of the first connecting bracket is fixedly connected to the bottom of the perforated plate. One end of each of the four second connecting brackets is slidably fitted onto four sliding rods. The other ends of each of the four second connecting brackets are fixedly connected to the four bottom corners of the same perforated plate. The vacuum cleaner is fixedly installed at the top of the pretreatment channel for absorbing smoke and dust. The suction end of the vacuum cleaner penetrates through the top of the pretreatment channel and extends into the interior of the pretreatment channel.
[0010] In one possible design, a valve is provided on the feeding pipe, and two support rods are fixedly connected to the outside of the feeding pipe, with one end of each support rod fixedly connected to the bottom of the same pretreatment channel.
[0011] In one possible design, baffles are fixedly connected to the inner walls on both sides of the pretreatment channel to prevent the perforated plate from detaching from the pretreatment channel.
[0012] In one possible design, a connecting plate is fixedly connected to the outside of the feeding pipe, and a collection box for collecting dust and impurities is fixedly connected to one side of the connecting plate.
[0013] In one possible design, slots are provided on both inner walls of the collection box, and each slot is fitted with a locking block. The side of the two locking blocks that are close to each other is fixedly connected to the same partition to prevent dust from falling.
[0014] In this application, during use, the user first monitors and adjusts the equipment's operating status via the display on the controller. The tank, as the main fermentation container, is sealed at the top with a lid to ensure the internal fermentation environment is not disturbed by external factors. Temperature and humidity sensors installed on the lid monitor the temperature and humidity conditions inside the tank in real time, ensuring the tobacco leaves are in the optimal rehydration and fermentation environment. Based on the feedback from the temperature sensor, the heating element heats the tank to meet the requirements of the fermentation process. A motor is fixedly installed on the top of the lid, and its output shaft penetrates the lid and extends into the tank, connecting to a turning mechanism for periodically turning the tobacco leaves to promote uniform fermentation. The operating cycle and intensity of the turning mechanism can be adjusted via the controller to adapt to the fermentation needs of different batches of tobacco leaves. The feeding pipe allows the user to add tobacco leaves or other necessary fermentation agents into the tank. Before adding the tobacco leaves, they undergo dust removal treatment by a pretreatment mechanism. The pretreatment mechanism includes an inclined pretreatment channel with a bottom section... The perforated section allows the dust-removed tobacco leaves to fall into the feeding pipe below. A perforated plate with small holes is slidably installed inside the pretreatment channel. The up-and-down movement of the perforated plate is controlled by a mechanical system to vibrate it. When the tobacco leaves slide onto the perforated plate, dust and impurities are shaken off. Simultaneously, the suction end of a vacuum cleaner extends into the pretreatment channel to suck up the dust blocked and stirred up by the perforated plate, thus achieving dust removal of the tobacco leaves. Baffles are added to the inner walls on both sides of the pretreatment channel to effectively prevent the perforated plate from derailing during movement, enhancing structural stability. In addition, two support rods are fixedly connected to the outside of the feeding pipe, with the other end of the support rods connected to the bottom of the pretreatment channel, providing additional stability to the pretreatment mechanism. A connecting plate and a collection box are also added to the outside of the feeding pipe. The collection box is connected to the slot on the connecting plate via a locking block and contains a partition to collect dust and impurities falling from the pretreatment channel. This design not only facilitates the cleaning of dust and impurities but also helps maintain the cleanliness and hygiene of the equipment.
[0015] The beneficial effects of this utility model are as follows:
[0016] In this invention, the tobacco leaves are regularly turned over and the fermentation environment is monitored, which promotes uniform fermentation of the tobacco leaves and improves fermentation efficiency. At the same time, the design of the pretreatment mechanism effectively removes most of the dust on the tobacco leaves, providing purer raw materials for the subsequent fermentation process. It also reduces internal pollution and wear and tear on the equipment, ensuring the quality of the tobacco leaves. The design of the collection box facilitates the cleaning of dust and impurities, helps to keep the equipment clean and hygienic, and extends the service life of the equipment.
