TECHNICAL FIELD
[0001] The utility model relates to meat product fermentation technical field, specifically is a meat product even pickling fermentation device. BACKGROUND
[0002] Meat product fermentation refers to under natural or artificial control conditions, using the fermentation of microorganism or enzyme, a series of biochemical changes and physical changes of raw meat occur, and then meat products with special flavor, color and texture are formed, and have longer shelf life. This kind of fermented meat product has the remarkable advantages of rich nutrition, unique flavor and long shelf life: through the fermentation of beneficial microorganisms, the denaturation and degradation of protein in meat can be promoted, not only the product texture is effectively improved, but also the human body absorption rate of protein is improved; at the same time, beneficial microorganisms (such as lactic acid bacteria, yeast, etc.) in meat can produce lactic acid, lactic acid bacteria and other metabolites, reduce the pH value of meat, form competitive inhibition to pathogenic bacteria and spoilage bacteria, and the moisture content of meat is reduced during fermentation, which improves the edible safety of the product and prolongs its shelf life.
[0003] At present, the equipment commonly used in meat product fermentation processing mainly includes two types: one is fermentation room or fermentation box, which is suitable for the suspension fermentation of long strip-shaped meat products (such as sausages, bacon, etc.), or the flat fermentation of block-shaped or sheet-shaped meat products; the other is fermentation tank, which is more suitable for the drum rotation fermentation of minced meat restructured meat products. When using fermentation tank for minced meat restructured meat product fermentation, the industry generally adopts vacuum tumbling machine for integrated processing of pickling and fermentation. Through the rotating movement of the drum, the meat product, pickling liquid and fermentation agent are synchronously turned upward, and combined with the vacuum environment built in the equipment, the rapid flavoring and relatively stable fermentation of the material can be realized, which significantly improves the processing efficiency.
[0004] However, the core structure of the existing vacuum tumbling machine is usually as follows: the drum is open at one end and movably connected with a cover body to facilitate the feeding and discharging of materials; the cover body is connected with a vacuum pipe at the center position for building a vacuum environment in the equipment; and a transmission mechanism is coaxially connected with the other end of the drum to drive the drum to rotate on the frame. Although this structure design can meet the basic requirements of vacuum pickling and fermentation, in the fermentation stage, it is necessary to accurately control the temperature and humidity in the drum to ensure the stability of the fermentation process. Usually, saturated steam or dry air with preset parameters needs to be introduced into the drum, and the drum needs to be heated to maintain the set temperature. However, only relying on the vacuum pipe at the center of the cover body cannot realize the effective introduction of saturated steam or dry air, and it is difficult to meet the humidity control and auxiliary temperature control requirements in the fermentation stage.
[0005] On the other hand, the existing structure also presents significant obstacles when heating and maintaining the temperature of the drum during fermentation. Since the drum is mounted on the frame via a transmission mechanism, with one end connected to the transmission mechanism and the other end (the open end of the cover) connected to a vacuum tube, if a sandwiched drum design (heating by introducing steam into the sandwich) is used, the connection between the steam pipe and the drum sandwich will fail due to the drum's rotation. If heating is achieved by placing a heating pipe at the bottom of the drum, the rotation of the drum and external environmental interference will prevent uniform heating and stable temperature maintenance, thus affecting the fermentation quality of the meat products and leading to differences in the flavor and texture of the finished product. Utility Model Content
[0006] Therefore, to address the shortcomings mentioned above, this utility model provides a uniform marinating and fermentation device for meat products. This device has a cover and a drain pipe at the open end of the drum, which can be used to extract internal air to create a vacuum environment for vacuum fermentation. An inlet pipe is provided at the other end of the drum, allowing saturated steam or dry air to be introduced, thus facilitating humidity control within the drum to promote meat product fermentation. Simultaneously, combined with the external cavity of the drum, gas at a preset temperature can be introduced into the cavity. The internal temperature of the drum can be controlled using the principle of heat conduction, further promoting meat product fermentation and ensuring fermentation quality. Furthermore, combined with the lifting mechanism and the connection method of the cavity, the drum can be rotated to discharge internal materials.
[0007] This invention is achieved as follows: a meat product uniform marinating and fermentation device includes a drum, which is rotatably arranged in a cavity to accommodate meat products for fermentation.
[0008] The inlet pipe has one end connected to the end of the drum and keeps it rotating, while the other end is connected to an external air or water source through a valve body.
[0009] The pipe has one end connected to the cover attached to the open end of the drum and keeps rotating, and the other end is connected to an external vacuum machine or waste gas and wastewater tank through a valve body.
[0010] One end of the cavity is rotatably mounted above the frame, and the other end is raised and lowered by a lifting mechanism. The rotatable end of the cavity is the end of the cover near the roller.
[0011] Preferably, one end of the roller is closed and an inlet pipe is installed coaxially on the closed end through a rotating connector. The inlet pipe is kept in communication with the inside of the roller. The other end of the roller is tapered and has an opening at the end. The cover is movably connected to the open end of the roller and is kept in a sealed connection. One end of the drain pipe is coaxially connected through the cover and communicates with the inside of the roller, and is kept in a rotating connection through a rotating connector.
[0012] Preferably, a partition plate is arranged along the inner circumference of the roller in parallel with the feeding direction of the roller.
[0013] Preferably, the inlet pipe and the outlet pipe are connected to the valve body and the external device through flexible pipes.
[0014] Preferably, a screw connection part is arranged outside the open end of the roller, the cover body is screwed on the screw connection part at the outer end of the roller, and a sealing member is arranged on the contact part between the inner end of the cover body and the roller to keep the connection airtight.
[0015] Preferably, a gear ring and a rolling ring are arranged at the outer end of the roller, the rolling ring includes at least two and is arranged at the two ends of the roller respectively, a driving rod is arranged inside the cavity and rotates, the driving rod is arranged in parallel with the outer end of the roller and is driven to rotate by a driving motor, a gear and a support ring are arranged on the driving rod, the gear is engaged with the gear ring, and the support ring is in contact with the rolling ring to keep rolling connection.
[0016] Preferably, a limiting boss is arranged at at least one end of the support ring, and the roller is placed on the support ring through the rolling ring and is limited by the limiting boss.
[0017] Preferably, the lifting mechanism is a linear extension device, and the two ends of the linear extension device are rotatably connected between the cavity and the frame.
[0018] Preferably, a strip-shaped hole is arranged on the frame, a mounting plate is arranged on the bottom of the frame in vertical with the strip-shaped hole, one end of the linear extension device is rotatably connected outside the mounting plate, and the other end is rotatably connected below the end of the cavity away from the rotating end through the strip-shaped hole, when the cavity rotates to the horizontal state in contact with the frame with the movement of the linear extension device, the linear extension device stops running and is in the inclined state.
[0019] Preferably, a support rod is arranged through the inlet pipe, the outer end of the support rod is connected to the inner wall of the inlet pipe through a connecting ring and forms a gap, one end of the support rod extends to the inside of the roller and is provided with a sensor at the end, and the other end of the support rod is connected to the external circuit through the inlet pipe.
[0020] Compared with the prior art, the utility model has the advantages that:
[0021] Firstly, compared with the traditional vacuum tumbling machine, the device constructs the independent channel structure of "air / water inlet-air / water outlet" through the independently arranged inlet pipe and outlet pipe. One end of the inlet pipe is in rotating communication with the end part of the drum, and the other end can be connected with external air source or water source, which can accurately introduce saturated steam, dry air and other media according to the fermentation demand, and realize the function switching of vacuum extraction and waste gas and waste water discharge in cooperation with the outlet pipe, so as to facilitate the regulation and control of the humidity in the drum and the fermentation of meat products, and also facilitate the subsequent cleaning of the inside of the drum.
[0022] Secondly, the partition plates distributed in the circumference of the drum are arranged in parallel along the feeding direction, which can ensure that the meat products can be turned up during the rotation of the drum, avoiding the problem that the marinated meat products cannot be turned up upward due to insufficient friction with the inner wall of the drum because the inner wall of the drum is a smooth surface.
[0023] Thirdly, one end of the cavity is rotationally arranged, and the other end is lifted through the linear extension device, so that the inclination angle of the cavity and the internal drum can be changed by adjusting the lifting mechanism. The inclination angle can be adjusted to a horizontal state to ensure the tumbling effect during marinating and fermentation, and the inclination angle can be increased to realize automatic discharge of the material during discharging. Compared with the existing vacuum tumbling machine with a fixed structure, the feeding and discharging operation process is greatly simplified. At the same time, the opening end of the cover and the drum is designed in a threaded connection mode with a sealing element, which not only ensures the airtightness of the device to maintain the vacuum environment or a specific fermentation atmosphere, but also facilitates the disassembly and maintenance of the cover.
[0024] Finally, one end of the inlet pipe and the outlet pipe away from the drum is connected with an external device through a hose, and the design of the rotating connecting piece not only meets the rotation movement demand of the drum, but also meets the extension adaptability of the pipeline during the lifting of the cavity, avoiding the problem of medium leakage caused by pipeline pulling and damage. In addition, the gear ring sleeved on the outer end of the drum is meshed and transmitted with the gear on the driving rod, and the rolling support structure of the rolling ring and the supporting ring can provide stable rotation support for the drum. The limiting boss at the end of the supporting ring can effectively prevent the axial deviation of the drum, further improving the stability and reliability of the long-term operation of the equipment.
