Description

Technical Field

[0001] The present invention relates to the technical field of feed processing, in particular to a device for preparing highly efficient fermented feed for mutton sheep. Background Art

[0002] At present, the mutton breeding industry is booming. The growth performance, health level and economic benefits of mutton sheep are closely related to the rise and fall of the entire industry. High-quality fermented feed, as a key source of nutrition for the growth of mutton sheep, plays an irreplaceable and important role in it. High-quality fermented feed can not only provide mutton sheep with more comprehensive and easily digestible nutrients, effectively promote the growth and development of mutton sheep, increase their growth rate and weight gain, but also enhance the immunity of mutton sheep, reduce the risk of disease, and ensure their healthy growth. At the same time, a good feed conversion rate can reduce breeding costs, improve breeding economic benefits, and bring more substantial profits to farmers. However, traditional mutton sheep feed fermentation processes and equipment are like obstacles hidden in the dark in actual application scenarios, exposing many difficult problems, seriously limiting the improvement of fermented feed quality and production efficiency, and becoming a bottleneck for the mutton breeding industry to move to a higher level.

[0003] From the perspective of environmental control, existing technologies make it difficult to achieve precise control of multiple parameters of the fermentation process; in terms of temperature control, simple heating rods or air cooling devices make it difficult to stabilize the temperature in the optimal range of 25-35°C when the ambient temperature fluctuates, resulting in inhibition of microbial metabolism, prolonged fermentation cycle and even inactivation of microorganisms; in terms of humidity control, there is a lack of effective layered management and multi-adjustment means, the humidity of raw materials is uneven, and when the humidity is too high, the efficiency is low and it is easy to cause nutrient loss; in the oxygen supply link, the control of the aerobic stage in the early stage of fermentation is not precise, and insufficient or excessive oxygen affects the fermentation effect and feed quality; in summary, the existing mutton feed fermentation preparation device has obvious defects in key links such as environmental control and oxygen supply. In view of this, this paper proposes a preparation device for efficient fermentation feed for mutton. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Precise environmental control to improve fermentation quality: The temperature and pressure regulating chambers formed by the outer cylinder, inner cylinder, and filter support cylinder are coordinated with a water-cooled hot and cold circulation unit, a pressurized oxygen injection source, a negative pressure exhaust mechanism, etc., and combined with temperature, pressure, gas, and moisture sensors to achieve precise control of fermentation temperature, pressure, oxygen content, and moisture content; at a suitable temperature of 25-35°C, it provides an optimal growth environment for microorganisms, accelerates microbial metabolic activities, improves fermentation efficiency, ensures the stability and effectiveness of feed nutrients, improves the quality of fermented feed, and meets the growth needs of mutton sheep.

[0021] 2. Optimize the aerobic stage to ensure stable fermentation: In the aerobic stage of early fermentation, a gas sensor is used to detect the oxygen content and accurately control the oxygen injection from the pressurized oxygen injection source. Oxygen diffuses into the raw materials through a specially designed filter support tube and filter bag, and the stirring mechanism is used to ensure full contact between oxygen and the raw materials. This can not only promote the rapid reproduction of yeast and lay the foundation for subsequent fermentation, but also effectively control the aerobic time and oxygen amount, avoiding the inhibition of lactic acid bacteria growth and the breeding of harmful bacteria, ensuring the stability of the fermentation process, improving feed quality, and reducing the risk of fermentation failure.

[0022] 3. Balance humidity distribution and adjust humidity in multiple ways: The filter bag cooperates with the drainage system to effectively block the raw materials from entering the pressure regulating chamber, and promptly discharge the accumulated liquid generated by the fermentation raw materials, ensuring that the humidity of the upper and lower layers of the fermentation raw materials is consistent, avoiding fermentation abnormalities caused by uneven humidity; at the same time, when the humidity of the fermentation raw materials is too high, through drainage, pressure reduction evaporation and auxiliary evaporation of water-cooled hot and cold circulation units and other multiple means, the humidity can be quickly reduced, the damage of high temperature to the raw material components can be reduced, a stable fermentation environment can be maintained, and smooth fermentation can be ensured.

[0023] 4. Innovative feeding and discharging design improves production efficiency: The feeding mechanism uses the ingenious design of the cross turntable and the discharge port to accurately control the feeding speed and amount, ensure the sealing of the feeding process, and prevent external impurities from entering and affecting fermentation; when discharging, the two symmetrical discharge ports, combined with the rotatable sealing door and ring, can quickly complete the discharging operation. Compared with traditional designs, it greatly shortens the feeding and discharging time, improves production efficiency, and reduces labor costs.

[0024] 5. Strengthen mixing and material collection to promote uniform fermentation: The spiral rod under the four-finger stirring paddle enhances the mixing effect, so that oxygen, water and fermentation raw materials are evenly mixed, promoting full contact between microorganisms and nutrients, accelerating the fermentation process, and ensuring that the fermentation degree of each part of the fermentation raw materials is consistent; the barbs on the side plates of the cross turntable assist in collecting the crushed materials to ensure smooth feeding, and work together with precise feeding and efficient mixing to further improve the stability of feed quality and the efficiency of the production process.

[0040] refer to Figure 7 As shown, a feeding mechanism 5 is fixedly installed above the cover plate 109. The feeding mechanism 5 is composed of a hopper 501, a cylindrical funnel 502, a cross-turn plate 503 and a reduction motor 504. The hopper 501 and the reduction motor 504 are fixedly connected to the cover plate 109. The cross-turn plate 503 is composed of four side plates. A rotating shaft 505 is fixedly installed at the center of the cross-turn plate 503. The four side plates are fixed to the periphery of the rotating shaft 505. The rotating shaft 505 is located on the central axis of the cylindrical funnel 502.

The end of the side plate of the cross turn plate 503 is closed and slidably connected to the inner wall of the cylindrical funnel 502. The diameter of the discharge port 508 is larger than the length of a single side plate of the cross turn plate 503 when the cross turn plate 503 is in a horizontal state, and smaller than the distance between the diagonal vertices, so as to achieve effective control of the falling of the material and seal the inner cavity. In addition, a number of barbs 509 are installed on one side of the side plate of the cross turn plate 503 to assist in collecting the crushed material.

The moisture sensor 111, the pressure sensor 112, the temperature sensor 113, and the gas sensor 114 are all signal-connected to the control cabinet 7. The control cabinet 7 is electrically connected to the electric valve on the water supply pipe 110, the water-cooled hot and cold circulation unit 2, the two-position three-way solenoid valve 108, the pressurized oxygen injection source 3, and the negative pressure exhaust mechanism 4.

[0044] In this embodiment, the working process of the device for preparing efficient fermented feed for mutton sheep is as follows:

[0045] 1. Feeding stage

[0046] 1.1. Raw material filling: Pour the raw materials to be fermented into the hopper 501. At this time, the reduction motor 504 is in a standby state, and the cross-turn plate 503 is stationary to prevent the materials from falling.

[0047] 1.2. Material discharge control: When feeding is required, the control cabinet 7 sends a command to the reduction motor 504, and the reduction motor 504 starts to operate. The rotor output end of the reduction motor 504 drives the rotating shaft 505 to rotate through the pulley 506 and the belt ring 507, thereby causing the cross-turn plate 503 to rotate around the central axis of the cylindrical funnel 502. The barbs 509 on the side panels of the cross-turn plate 503 help to collect the crushed materials, making the materials fall more smoothly. At the same time, it ensures that when the materials are not discharged, they can effectively block the materials and maintain the sealing of the inner cavity at the lower end of the feeding mechanism 5.

[0048] 2. Fermentation stage

[0049] 2.1. Temperature control: The temperature sensor 113 monitors the temperature inside the silo-type fermenter 1 in real time and transmits the data to the control cabinet 7. Within the suitable fermentation temperature range of 25-35°C, the microbial metabolic activity is vigorous and the fermentation speed is fast. The fermentation time is usually 3-5 days. When the temperature is higher than 35°C, the control cabinet 7 controls the water-cooled hot and cold circulation unit 2 to start the cooling mode. The low-temperature coolant flows into the water inlet pipe 117 at the lower end of the temperature control chamber 104 through the water outlet of the water-cooled hot and cold circulation unit 2, circulates in the temperature control chamber 104, absorbs the heat in the silo-type fermenter 1, and then flows out from the water outlet pipe 118 at the upper end of the temperature control chamber 104 and returns to the water-cooled hot and cold circulation unit 2. When the temperature is lower than 25°C, the water-cooled hot and cold circulation unit 2 switches to the heating mode, and transports high-temperature coolant into the temperature control chamber 104 to increase the temperature inside the silo-type fermenter 1.

[0050] 2.2 Oxygen supply and pressure regulation: During the short aerobic stage of the early fermentation of mutton feed, the gas sensor 114 monitors the oxygen content in the silo-type fermentation tank 1 in real time, and the pressure sensor 112 monitors the pressure in the tank in real time. When the oxygen content is lower than the set lower limit and the pressure is within the normal range, the control cabinet 7 controls the two-position three-way solenoid valve 108 to connect its common port with the high-pressure oxygen tank of the pressurized oxygen injection source 3, injecting oxygen into the pressure regulating chamber 105, and the oxygen diffuses and penetrates into the fermentation tank through the filter support cylinder 103 and the filter bag 106. On the raw materials, at the same time, the control cabinet 7 starts the stirring mechanism 6, and the stirring motor 601 drives the four-finger stirring paddle 602 and the screw rod 603 below to stir the fermentation raw materials, so that oxygen is fully in contact with the fermentation raw materials. When the pressure is higher than the set upper limit, the control cabinet 7 controls the switching of the two-position three-way solenoid valve 108 so that its common port is connected to the vacuum pump of the negative pressure exhaust mechanism 4 to extract the excess gas in the tank and reduce the pressure; when the pressure is lower than the set lower limit, the two-position three-way solenoid valve 108 is switched again to allow the pressurized oxygen injection source 3 to replenish gas into the tank and increase the pressure.

[0051] 2.3. Moisture Management: The moisture sensor 111 continuously detects the humidity of the fermentation raw materials. The suitable moisture content of the fermentation raw materials is generally 40%-60%. When the humidity is lower than 40%, the control cabinet 7 controls the electric valve on the water supply pipe 110 to open, spraying water to the fermentation raw materials. At the same time, the stirring mechanism 6 is started, and the stirring motor 601 drives the four-finger stirring paddle 602 and the screw rod 603 to stir, so that the water and the fermentation raw materials are evenly mixed. When the humidity is higher than 60%, on the one hand, the control cabinet 7 controls the electric water valve 116 to open at a fixed time, and the accumulated liquid that permeates downward from the fermentation raw materials passes through the pressure regulating chamber 105 and is discharged through the drain pipe 115; on the other hand, the two-position three-way solenoid valve 108 is controlled to connect the pressure regulating chamber 105 with the negative pressure exhaust mechanism 4, reducing the pressure in the silo-type fermenter 1, lowering the boiling point of water, and quickly evaporating water at a low temperature. During this process, the water-cooled hot and cold circulation unit 2 cooperates to maintain the temperature of the liquid medium in the temperature regulating chamber 104, accelerating the evaporation rate of water.

[0052] 3. Discharging stage

[0053] After fermentation is completed, the operator drives the two sealing doors 121 and the two rings 120 to rotate along the outer wall of the outer cylinder 101 through the handle 122, so that the two sealing doors 121 rotate away from the two discharge ports 119 at the same time, open the discharge ports 119, and the fermented feed is quickly discharged from the two mutually symmetrical discharge ports 119. After the discharge is completed, the handle 122 is rotated in the opposite direction so that the two sealing doors 121 cover the two discharge ports 119 at the same time, and the silo-type fermenter 1 is sealed to prepare for the next fermentation.
