Description

Technical Field

[0001] The invention belongs to the technical field of feed fermentation, and relates to a liquid feed, in particular to a liquid feed with an anti-diarrhea function and a fermentation preparation process thereof. Background Art

[0002] Liquid feed feeding has become a common feeding method in the breeding industry. During the production process of liquid feed, fermentation treatment is required to allow the bacteria to fully grow in the feed and improve the absorption effect of the feed.

[0003] After searching, it was found that Chinese patent literature discloses cassava residue liquid feed and its preparation method [Application number: 201811037857.5; Publication number: CN 108740299 A]. This preparation method includes the following steps: taking wet cassava residue, heating it to 70-80°C and keeping it warm for 0.5-1 hour, then cooling it to 55-65°C, adding α-amylase and keeping it warm for 0.5-1 hour to obtain a first-level hydrolyzate; cooling the first-level hydrolyzate to 45-55°C and adjusting the pH to 4-5, then adding pectinase and cellulase and keeping it warm for 0.5-3 hours to obtain a second-level hydrolyzate; cooling the second-level hydrolyzate to 25-35°C, adding calcium carbonate, Aspergillus niger, Candida aeruginosa, and one or both of urea and ammonium sulfate, and fermenting it for 4-12 hours to obtain a first-level fermentation product; heating the first-level fermentation product to 35-40°C, adding Lactobacillus plantarum, and fermenting it for 4-12 hours to obtain a second-level fermentation product; and adding auxiliary materials to the second-level fermentation product. The fermentation cycle is short, the production cost is low, and the resulting cassava residue liquid feed is nutritionally balanced. This method fully utilizes the cassava residue and reduces the pollution it causes to the ecological environment.

[0004] Although the liquid feed and its preparation method disclosed in this patent have a short fermentation cycle and low production cost, and the obtained cassava residue liquid feed is nutritionally balanced, the liquid feed needs to be subjected to multi-level control of the fermentation temperature during processing. The existing method of cooling and heating the liquid feed usually uses a combination of refrigeration equipment and heating equipment, which not only wastes energy but also causes large temperature changes in a short period of time, affecting the quality of fermentation.

A first motor is fixed on the upper side of the base. The output shaft end of the first motor is fixed to a first rotating disk. A first heating component, a second heating component and a third heating component are provided on the upper side of the first rotating disk. The first heating component, the second heating component and the third heating component have the same structure. The first heating component includes a heating box.

A connecting seat is fixed to the telescopic end of the first electric telescopic rod. The outside of the heating box Two first telescopic tubes are connected, a liquid delivery cavity is provided in the connecting seat, the first telescopic tube is connected to the liquid delivery cavity, a telescopic slot is provided on the connecting seat, a connecting tube is slidably connected in the telescopic slot, one end of the connecting tube extending into the liquid delivery cavity is a closed structure, a connecting port is provided on the outer periphery of the connecting tube, a mounting plate is fixed inside the liquid delivery cavity, a spring is fixed between the mounting plate and the connecting tube, a heating cavity is provided in the tank wall of the fermentation tank, a heat exchange tube is wound in the heating cavity, the liquid inlet and liquid outlet ends of the heat exchange tube are both connected with a circulation tube, a circulation pump is fixed on one of the circulation tubes, the circulation tube can be inserted into the telescopic slot, a plurality of support legs are fixed on the lower side of the first rotating disk, and ball bearings are provided on the support legs.

[0018] With the above structure, cassava residue is added into three fermentation tanks, and deionized water in the preheating box is added into the fermentation tank. The first motor drives the first rotating disk to rotate. After the first rotating disk rotates the heating box of the first-level heating component to a position corresponding to one of the fermentation tanks, the first electric telescopic rod drives the connecting seat to extend and retract, so that the circulation pipe on the fermentation tank is extended and retracted into the telescopic groove of the connecting seat, thereby pushing the connecting pipe in the telescopic groove, so that the connecting port on the connecting pipe is located in the liquid feeding cavity, so that the heating cavity and the heat exchange pipe are connected. At this time, the circulation pump is turned on, and the heating liquid in the heating cavity is used to circulate heat exchange in the heat exchange pipe, so as to achieve heating in the fermentation tank, thereby utilizing the first The heating component is heated to 60-70°C and kept warm for 20-40 minutes, and then α-amylase is added and fermented for 30-50 minutes to obtain a primary fermentation product; the above method is also used to move the heating box of the secondary heating component to the corresponding position of the fermentation tank and then connect it, and the secondary heating component is used to cool the primary fermentation product to 45-55°C, and adjust the pH value to 4.5-5.5, and then pectinase and cellulase are added, and fermented for 50-80 minutes to obtain a secondary fermentation product; the above method is also used to move the heating box of the tertiary heating component to the corresponding position of the fermentation tank and then connect it, and the tertiary heating component is used to cool the secondary fermentation product to 30-4 0℃, add butterfly pea pollen, honeysuckle extract, Aspergillus niger, chasteberry extract, and Candida albicans, and ferment for 120min-300min at a temperature of 300℃ to obtain a tertiary fermentation product; similarly, the above method is used to move the heating box of the secondary heating component to the position corresponding to the fermentation tank and connect it, and use the secondary heating component to heat the tertiary fermentation product to 45-55℃, add ammonium sulfate and composite bacterial liquid, and ferment for 120min-300min at a temperature of 300℃ to obtain a crude liquid feed product. The setting of the three fermentation tanks can stagger the fermentation time of the three fermentation tanks. When the first fermentation tank is undergoing primary fermentation, the second fermentation tank can be used for secondary fermentation, and the third fermentation tank can be used for secondary fermentation. Three-stage fermentation can not only improve the compactness of the device, but also reduce the cost of using the equipment, so that the heating liquid in the heating box will not be wasted due to long-term idling and heating, and it is highly practical. In addition, by using the settings of the first-stage heating component, the second-stage heating component and the third-stage heating component, there is no need to set up a refrigeration component when heating and cooling. Not only does it further reduce the cost of using the equipment, but it also prevents the temperature from changing too quickly in a short period of time when the temperature is switched, thereby ensuring the quality of the fermentation. At the same time, the deionized water is preheated before fermentation, so that the material will not be heated from a lower temperature. On the one hand, the efficiency of the fermentation is improved, and on the other hand, the quality of the fermentation can be improved.

[0020] With the above structure, when supplying water to the fermentation tank, the first motor can be used to drive the first rotating disk to rotate, thereby driving the second rotating disk to rotate through the heating box, so that the delivery pipe corresponds to the corresponding fermentation tank, and the second electric telescopic rod drives the connecting plate to move outward, so that the delivery pipe is inserted into the connecting seat, so that the delivery pipe is connected with the second telescopic pipe, and then the water pump is used to supply water to the fermentation tank. Two water tanks are provided, and the two water tanks can be controlled in turn by the solenoid valve to discharge water. While ensuring the water supply to the fermentation tank, the temperature of the water can be guaranteed to meet the requirements, preventing the same water tank from discharging too much water at one time and affecting the water temperature. At the same time, when one of the water tanks fails, the other water tank can also be used to operate, further improving the stability of the device.

At the same time, under the action of the first bevel gear and the second bevel gear, the stirring blade is driven to rotate, thereby realizing the up and down stirring of the material, thereby further dispersing the lifted material up and down, improving the fermentation effect, and considering that the concentration of the material is higher as it goes down, the diameter of the second bevel gear arranged from top to bottom decreases successively, so that the speed of the stirring blade increases successively from top to bottom, thereby reducing energy consumption while ensuring the stirring effect, and having strong practicality.

[0023] Compared with the existing technology, the liquid feed with anti-diarrhea function and its fermentation preparation process have the following advantages:

At this time, the circulation pump is turned on, and the heating liquid in the heating cavity is used to circulate heat exchange with the heat exchange pipe to achieve heating in the fermentation tank, thereby utilizing the first-level heating component. Heat to 60-70°C, keep warm for 20-40 minutes, then add α-amylase, keep warm and ferment for 30-50 minutes to obtain a primary fermentation product; similarly, use the above method to move the heating box of the secondary heating component to the corresponding position of the fermentation tank and connect it, use the secondary heating component to cool the primary fermentation product to 45-55°C, and adjust the pH value to 4.5-5.5, then add pectinase and cellulase, keep warm and ferment for 50-80 minutes to obtain a secondary fermentation product; similarly, use the above method to move the heating box of the tertiary heating component to the corresponding position of the fermentation tank and connect it, use the tertiary heating component to cool the secondary fermentation product to 30-40°C, Add butterfly pea pollen, honeysuckle extract, aspergillus niger, chasteberry extract, and candida albicans, and ferment for 120min-300min to obtain a tertiary fermentation product; similarly, the above method is used, and the heating box of the secondary heating component is moved to the position corresponding to the fermentation tank and connected, and the tertiary fermentation product is heated to 45-55°C by the secondary heating component, and ammonium sulfate and composite bacterial liquid are added, and fermented for 120min-300min to obtain a crude liquid feed. The setting of the three fermentation tanks can stagger the fermentation time of the three fermentation tanks. When the first fermentation tank is undergoing primary fermentation, the secondary fermentation can be carried out on the second fermentation tank, and the third fermentation can be carried out on the third fermentation tank. The three-stage fermentation not only improves the compactness of the device, but also reduces the use cost of the equipment, so that the heating liquid in the heating box will not be wasted due to long-term idling, and is highly practical. In addition, by utilizing the settings of the first-stage heating component, the second-stage heating component and the third-stage heating component, there is no need to set up a refrigeration component when heating and cooling. This not only further reduces the use cost of the equipment, but also prevents the temperature from changing too quickly in a short period of time when the temperature is switched, thereby ensuring the quality of the fermentation.

When supplying water to the fermentation tank, the first motor can be used to drive the first rotating disk to rotate, thereby driving the second rotating disk to rotate through the heating box, so that the delivery pipe is aligned with the corresponding fermentation tank, and the second electric telescopic rod drives the connecting plate to move outward, so that the delivery pipe is inserted into the connecting seat, so that the delivery pipe is connected with the second telescopic pipe, and then the water pump is used to supply water to the fermentation tank. Two water tanks are provided, and the two water tanks can be controlled in turn by the solenoid valve to discharge water. While ensuring the water supply to the fermentation tank, the temperature of the water can be guaranteed to meet the requirements, preventing the same water tank from discharging too much water at one time and affecting the water temperature. At the same time, when one of the water tanks fails, the other water tank can also be used to operate, further improving the stability of the device.

[0028] 5. During the fermentation operation, the second motor drives the stirring column to rotate, and the stirring column drives the lifting blade and the stirring blade to revolve. The lifting blade uses its inclined surface to lift the material at the bottom of the fermentation tank, and the stirring blade stirs the material.

The three-stage fermentation is carried out on the upper part, which not only improves the compactness of the device, but also reduces the use cost of the equipment, so that the heating liquid in the heating box 4 will not be wasted due to long-term idling and heating, and the practicality is strong. In addition, by utilizing the setting of the first-stage heating component, the second-stage heating component and the third-stage heating component, there is no need to set a refrigeration component when heating and cooling. Not only does it further reduce the use cost of the equipment, but it also prevents the temperature from changing too quickly in a short period of time when the temperature is switched, thereby ensuring the quality of the fermentation. At the same time, the deionized water is preheated before fermentation, so that the material will not be heated from a lower temperature. On the one hand, the efficiency of the fermentation is improved, and on the other hand, the quality of the fermentation can be improved.

A water outlet pipe 20 is fixed at the lower end of the water tank 17, and a solenoid valve 21 is fixed on each of the two water outlet pipes 20. The two water outlet pipes 20 are connected to a water supply pipe 19 through a tee. A water pump 7 is fixed on the preheating box 6, and the water outlet end of the water supply pipe 19 is connected to the water inlet end of the water pump 7. The water outlet end of the water pump 7 is fixed with a delivery pipe 8. A second electric telescopic rod 22 is fixed on the fermentation tank 2, and a connecting plate 24 is fixed to the telescopic end of the second electric telescopic rod 22. A connecting plate 24 is fixed to the connecting plate 24. A connecting seat 25 is fixed to the connecting plate 24. The fermentation pipe is connected with a second telescopic pipe 23, and the second telescopic pipe 23 is connected to the connecting seat 25. The delivery pipe 8 can be inserted into the insertion port 26 of the connecting seat 25.

[0067] With the above structure, when supplying water to the fermentation tank 2, the first motor 9 can be used to drive the first rotary disk 3 to rotate, thereby driving the second rotary disk 5 to rotate through the heating box 4, so that the delivery pipe 8 corresponds to the corresponding fermentation tank 2, and the second electric telescopic rod 22 drives the connecting plate 24 to move outward, so that the delivery pipe 8 is inserted into the connecting seat 25, so that the delivery pipe 8 is connected with the second telescopic pipe 23, and then the water pump 7 is used to supply water to the fermentation tank 2. Two water tanks 17 are provided, and the solenoid valve 21 can be used to control the two water tanks 17 to discharge water in turn. While ensuring the water supply to the fermentation tank 2, the temperature of the water can be guaranteed to meet the requirements, preventing the same water tank 17 from discharging too much water at one time and affecting the water temperature. At the same time, when one of the water tanks 17 fails, the other water tank 17 can also be used to operate, further improving the stability of the device.

[0068] A second motor 31 is fixed to the fermentation tank 2, and a stirring column 32 is fixed to the output shaft end of the second motor 31.

The second bevel gear 38 is meshed with the first bevel gear 37, and the diameter of the second bevel gear 38 arranged from top to bottom decreases successively.

[0069] With the above structure, during the fermentation operation, the second motor 31 drives the stirring column 32 to rotate, and the stirring column 32 drives the lifting blade 34 and the stirring blade 33 to revolve. The lifting blade 34 uses its inclined surface to lift the material at the bottom of the fermentation tank 2, and the stirring blade 33 stirs the material. At the same time, under the action of the first bevel gear 37 and the second bevel gear 38, the stirring blade 33 is driven to rotate, thereby achieving up and down stirring of the material, thereby further dispersing the lifted material up and down, improving the fermentation effect, and considering that the concentration of the material is higher as it goes down, the diameter of the second bevel gear 38 arranged from top to bottom decreases successively, so that the speed of the stirring blade 33 increases successively from top to bottom, thereby reducing energy consumption while ensuring the stirring effect, and having strong practicality.

[0092] Experimental example

[0093] The anti-diarrhea liquid feed prepared in Examples 1-4 was added to the feed of the farm animals respectively. After three days of feeding, the excretion of the farm animals was officially recorded within one week. The color, shape, odor and other characteristics of the feces were observed to determine whether the animals had diarrhea, and the diarrhea rate of the animals was calculated (diarrhea rate = number of diarrhea episodes / (number of animals consuming the anti-diarrhea liquid feed × number of test days) × 100%).
