Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable processing technology, specifically a segmented fermentation device for fruits and vegetables. Background Technology

[0002] Fruits and vegetables are a general term encompassing edible fruits and vegetables, and are a category of food. Different processing techniques are used depending on the product category. Fermentation is a new and sophisticated processing method that requires fermentation equipment.

[0003] Traditional single-spiral mixing devices can only achieve the function of simply turning or conveying materials, lacking the ability to process in stages. During the aerobic fermentation stage, when oxygen is required for fermentation, it is difficult to maintain the looseness of the materials. During the anaerobic fermentation stage, it cannot effectively isolate air, resulting in insufficient microbial activity, long fermentation cycle, and problems such as local accumulation and mold growth, and uneven generation of flavor substances. It cannot meet the differentiated needs of fruits and vegetables for oxygen environment and material state at different fermentation stages. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a segmented fermentation device for fruits and vegetables.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a segmented fermentation device for fruits and vegetables, comprising an upper chamber, a feeding hopper fixedly connected to the top of the upper chamber, a main turning assembly inside the upper chamber, a set of side turning assemblies inside the upper chamber, a lower chamber fixedly installed at the bottom of the upper chamber, a feeding port at the top of the upper chamber, a scraping assembly inside the lower chamber, an air pump fixedly installed on the outer surface of the lower chamber, an exhaust pipe fixedly connected to one end of the air pump, an air extraction pipe fixedly connected to the other end of the air pump, and the air extraction pipe extending into the interior of the lower chamber, and a discharge port at the bottom of the lower chamber.

[0006] Furthermore, the main material turning assembly includes a motor fixedly installed on the top of the upper chamber. The output end of the motor is fixedly connected to a rotating shaft, and the outer surface of the rotating shaft is rotatably connected to the inner wall of the upper chamber through a bearing. A spiral blade is fixedly connected to the outer surface of the rotating shaft.

[0007] Furthermore, the side-tipping material assembly includes an inclined plate fixedly connected to the outer surface of the upper cabin, a second motor is fixedly installed on the outer surface of the inclined plate, and a second rotating shaft is fixedly connected to the output end of the second motor.

[0008] Furthermore, the outer surface of the second rotating shaft is rotatably connected to both the inclined plate and the inner wall of the upper cabin, and a second spiral blade is fixedly connected to the outer surface of the second rotating shaft, and a protrusion is fixedly connected to the outer surface of the second spiral blade.

[0009] Furthermore, the scraping assembly includes an electric push rod fixedly installed at the bottom of the lower compartment, and the output end of the electric push rod is slidably connected to the inner wall of the upper compartment. A connecting plate is fixedly connected to the output end of the electric push rod.

[0010] Furthermore, a scraper ring is fixedly connected to the outer surface of the connecting plate, and the outer surface of the scraper ring is slidably connected to the inner wall of the lower compartment.

[0011] Compared with existing technologies, this segmented fermentation device for fruits and vegetables has the following advantages:

[0012] 1. This utility model, by setting a main turning component, can turn and mix the materials in the front stage. By setting a side turning component, it can turn and disperse the materials laterally at a slightly faster speed. The main turning component and the side turning component work together to achieve full contact and uniform mixing of oxygen in the initial aerobic fermentation stage. By using an air pump, air extraction pipe and exhaust pipe, air can be extracted from the lower chamber to create an anaerobic environment, realizing oxygen extraction in the later fermentation stage. Through the coordinated use of the main turning component, side turning component, air pump, air extraction pipe and exhaust pipe, a segmented processing mode of aerobic fermentation-anaerobic fermentation-dynamic conveying is realized in the same chamber. This solves the shortcomings of traditional single spiral devices that cannot meet the environmental requirements of different stages. In this way, it can improve microbial activity, shorten the fermentation cycle, ensure uniform generation of flavor substances, and improve the consistency of fermentation products.

[0013] 2. This utility model uses an electric push rod to drive the connecting plate and scraper ring to slide along the inner wall of the lower chamber, which can scrape off the material attached to the chamber wall, avoid material residue and waste, and improve the utilization rate of raw materials.

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] This embodiment provides a segmented fermentation device for fruits and vegetables. The device features a main turning component 3 for turning the initial material, and a side turning component 4 for laterally turning and dispersing the material at a slightly faster speed. The main turning component 3 and the side turning component 4 work together to ensure sufficient oxygen contact and uniform mixing during the initial aerobic fermentation stage. An air extraction pump 8, an extraction pipe 10, and an exhaust pipe 9 work together to extract air from the lower chamber 5, creating an anaerobic environment for the later fermentation stage. The coordinated use of the main turning component 3, the side turning component 4, the air extraction pump 8, the extraction pipe 10, and the exhaust pipe 9 achieves a segmented processing mode within the same chamber, encompassing aerobic fermentation, anaerobic fermentation, and dynamic conveying. This solves the shortcomings of traditional single-spiral devices that cannot meet the environmental requirements of different stages, thereby improving microbial activity, shortening the fermentation cycle, ensuring uniform generation of flavor substances, and enhancing the consistency of fermentation products.

[0021] See Figures 1-4 A segmented fermentation device for fruits and vegetables includes an upper chamber 1, and a lower chamber 5 is fixedly installed at the bottom of the upper chamber 1. The upper chamber 1 and the lower chamber 5 are made of corrosion-resistant material and have smooth inner walls for easy cleaning.

[0022] The top of the upper chamber 1 is fixedly connected to the feed hopper 2, which is funnel-shaped to facilitate the smooth entry of materials into the chamber. At the same time, a sealing cover is hinged to the top to prevent dust and impurities from entering the upper chamber 1 and contaminating the materials.

[0023] The upper chamber 1 has a feed inlet 6 at the top, and the other end of the air pump 8 is fixedly connected to the air extraction pipe 10, which extends into the interior of the lower chamber 5. The end of the air extraction pipe 10 is equipped with a filter structure to prevent material from entering the pipe. The lower chamber 5 has a discharge port 11 at the bottom. Electric valves are installed in the feed inlet 6, the air extraction pipe 10, and the discharge port 11. The electric valves are all linked to the control system through an external controller, and the opening and closing status is precisely controlled according to the fermentation stage to realize the automated operation of the segmented fermentation process.

[0024] An air pump 8 is fixedly installed on the outer surface of the lower hull 5, and an exhaust pipe 9 is fixedly connected to one end of the air pump 8.

[0025] The main material-turning assembly 3 is located inside the upper hull 1.

[0026] The main material turning assembly 3 includes a motor 301 fixedly installed on the top of the upper chamber 1. The motor 301 has an adjustable speed and drives the rotating shaft 302 to drive the spiral blades 303 to achieve the switching between low-speed turning and high-speed conveying.

[0027] The output end of motor 301 is fixedly connected to shaft 302, and the outer surface of shaft 302 is rotatably connected to the inner wall of upper hull 1 through bearing.

[0028] A spiral blade 303 is fixedly connected to the outer surface of the rotating shaft 302. The spiral blade 303 adopts a variable pitch structure, with denser pitch at the front and sparser pitch at the back, to meet the different needs of materials from accumulation and fermentation to rapid delivery.

[0029] The interior of the upper hull 1 is equipped with a set of side-tipping material assembly 4.

[0030] The side-tipping material assembly 4 includes an inclined plate 401 fixedly connected to the outer surface of the upper hull 1. The inclined plate 401 is designed with an inclined angle, which allows the rotating shaft 403 to penetrate into the material layer.

[0031] A motor 402 is fixedly installed on the outer surface of the inclined plate 401. A rotating shaft 403 is fixedly connected to the output end of the motor 402. The outer surface of the rotating shaft 403 is rotatably connected to both the inclined plate 401 and the inner wall of the upper chamber 1. A spiral blade 404 is fixedly connected to the outer surface of the rotating shaft 403. After the motor 402 is started, it will drive the rotating shaft 403, the spiral blade 404 and the protrusion 405 to rotate synchronously, thereby driving the spiral blade 404 and the protrusion 405 to disperse the material laterally.

[0032] The outer surface of the spiral blade 404 is fixedly connected with a protrusion 405. The protrusion 405 can enhance the dispersing effect of the material and, together with the main material turning component 3, form a three-dimensional turning and mixing, thereby improving the uniformity of material mixing and the efficiency of oxygen contact.

[0033] The lower compartment 5 is equipped with a scraping assembly 7.

[0034] The scraping assembly 7 includes an electric push rod 701 fixedly installed at the bottom of the lower chamber 5, and the output end of the electric push rod 701 is slidably connected to the inner wall of the upper chamber 1. A connecting plate 702 is fixedly connected to the output end of the electric push rod 701, and a scraping ring 703 is fixedly connected to the outer surface of the connecting plate 702. The outer surface of the scraping ring 703 is slidably connected to the inner wall of the lower chamber 5. The electric push rod 701 can drive the connecting plate 702 to drive the scraping ring 703 to slide along the chamber wall. The scraping ring 703 is made of elastic material, which can thoroughly scrape off the attached material, reduce waste, and avoid damaging the inner wall of the chamber. It works in conjunction with the automated control system to achieve periodic cleaning.

[0035] Working Principle: In use, fruit and vegetable materials enter the upper chamber 1 through the feed hopper 2. The motor 301 of the main turning assembly 3 starts, driving the rotating shaft 302 and the spiral blade 303 to rotate at low speed, turning the material in the front section. At the same time, the motor 402 of the side turning assembly 4 starts, driving the rotating shaft 403, the spiral blade 404, and the convex strip 405 to rotate synchronously. The spiral blade 404 and the convex strip 405 can laterally disperse the material, thereby promoting oxygen contact and meeting the requirements of aerobic fermentation. After aerobic fermentation is completed, the electric valve in the feed inlet 6 opens, and the material is slowly pushed to the lower chamber 5 by the main spiral blade 303. Then, the air pump 8 draws air from the lower chamber 5. Pipe 10 draws air from the lower chamber 5 and, together with exhaust pipe 9, discharges the gas, creating an anaerobic environment. After the material ferments in the lower chamber 5, the electric valve at discharge port 11 opens, and the material is discharged through discharge port 11 to a designated container. During the process, the electric push rod 701 of scraping component 7 is activated. The output end of electric push rod 701 drives connecting plate 702 to move downward. At this time, connecting plate 702 drives scraper ring 703 to slide downward along the inner wall of lower chamber 5, scraping off the material attached to the chamber wall to avoid material waste. The electric valves in inlet 6, exhaust pipe 10 and discharge port 11 are all linked by an external controller system, which precisely controls the opening and closing status according to the fermentation stage, realizing the automated operation of the segmented fermentation process.
