[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] The livestock feed sterilization and stirring equipment disclosed in the present invention is mainly used in the scenario where the stirring effect of the existing livestock feed sterilization and stirring equipment is poor.

[0016] Analysis of microorganisms and influencing components before and after feed sterilization 1. Test methods 1.1 Sample grouping and pretreatment In this experiment, 10 homemade rabbit feed samples were selected, and the sampling volume of each sample was 2kg. According to the different treatment methods, the samples were divided into two groups: Control group: No treatment was performed and served as the baseline group.

[0017] Sterilization group: Use special equipment to sterilize the samples.

[0018] After treatment, the two groups of samples were placed in the same experimental environment (temperature: 20°C, humidity: 65%) and left for 7 days before experimental analysis.

[0019] 1.2 Analysis of microbial hygiene indicators According to the relevant provisions of the national standard GB 14924.2-2001 "Hygienic Standards for Compound Feeds for Laboratory Animals", the microbial hygiene indicators in the samples are tested, including the total colony count, coliform group, mold and yeast count, and pathogenic microorganisms. By comparing with the standard values, the eligibility of each indicator is evaluated.

[0020] 1.3 Nutritional analysis After completing the microbial hygiene test, keep the sample group and control group that meet the sterilization standards for further analysis. According to GB 14924.3-2010 "Nutritional Composition of Laboratory Animal Formula Feed" standard, test the main nutritional components of the two groups of samples. Test items include but are not limited to: General ingredients: moisture, crude protein, crude fat, crude fiber, ash, calcium and total phosphorus.

[0021] Vitamin content: Vitamin A, D, E, B1, B2, B6 and niacin, etc.

[0022] Amino acids: lysine, arginine, histidine, phenylalanine + tyrosine, threonine, leucine, isoleucine and valine, etc.

[0023] Minerals: magnesium, potassium, sodium, iron, manganese, copper, zinc, iodine and selenium, etc.

[0024] 1.4 Data Statistical Analysis Data sets were established using Excel 2006 software, and statistical analysis was performed using SPSS 19.0. Normality tests were performed on measurement data, and data that met normal distribution were expressed as mean ± standard deviation (x̄ ± s). Variance homogeneity tests were performed, and if the data met homogeneity, one-way analysis of variance (ANOVA) was used for inter-group comparisons. If significant differences were detected, the Student-Newman-Keuls method was further used for intra-group comparisons. The statistical significance level was set at α = 0.05 (two-sided test).

[0025] 2 Test results Table 1 Determination results of sanitary microbial indicators in feed before and after sterilization

[0026] According to the data in Table 1, the sanitary microbial indicators in the feed of the equipment sterilization group were significantly reduced compared with the control group: Total colony count: After sterilization, it dropped from 2.3×10^4cfu / g to <10cfu / g, a decrease of 99.96%, indicating that the sterilization effect was significant.

[0027] The number of coliform bacteria: dropped from 7.6×10^2cfu / g to <30cfu / g, a decrease of more than 96%, which meets the feed hygiene standards.

[0028] Mold and yeast count: from 3.4×10^2cfu / g to <10cfu / g, a decrease of more than 97%. Pathogenic bacteria (Salmonella): not detected before and after sterilization, indicating that the equipment has a significant killing effect on pathogens. After the equipment is sterilized, the content of harmful microorganisms in the feed is significantly reduced, which fully complies with national standards (such as GB 13078-2017 "Feed Hygiene Standard"), ensuring the hygiene and safety of the feed.

[0029] Table 2 Effects of sterilization on conventional nutritional components of feed (g / kg)

[0030] According to the data in Table 2, the conventional nutritional components of the feed changed little before and after sterilization, indicating that the equipment had little damage to the nutritional components during the sterilization process: Moisture: decreased from 71.2±5.2 g / kg to 70.2±4.1 g / kg, with no significant change (P>0.05). Crude protein: decreased from 16.2±4 g / kg to 15.3±6 g / kg, with a loss rate of about 5.6%. Crude fat: decreased from 30.8±2.3 g / kg to 30.0±1.1 g / kg, with a loss rate of about 2.6%. Crude fiber: decreased from 12.8±7 g / kg to 11.2±8 g / kg, with a loss rate of about 12.5%. Crude ash, calcium, and total phosphorus: all changed insignificantly (P>0.05).

[0031] Equipment sterilization has little effect on the conventional nutrients of feed, especially the loss rate of crude protein and crude fat is low, indicating that the equipment can effectively retain the main nutrients of feed during the sterilization process.

[0032] Table 3 Effects of sterilization on the mineral content in feed

[0033] According to the data in Table 3, the mineral content in the feed changed little before and after sterilization: Iron: dropped from 450±15mg / kg to 412±15mg / kg, with a loss rate of about 8.4%. Manganese, sodium, magnesium, potassium, copper, zinc: the changes were not significant (P>0.05). Selenium: dropped from 0.15±0.01mg / kg to 0.12±0.01mg / kg, with a loss rate of about 20%.

[0034] Equipment sterilization has little effect on the mineral content in feed. Except for selenium, the loss rate of other minerals is less than 10%, indicating that the equipment can better retain the minerals in feed.

[0035] Table 4 Effects of sterilization on the vitamin content of feed (x±s)

[0036] According to the data in Table 4, sterilization has a significant effect on vitamins in feed, but the loss rate of some vitamins is still within an acceptable range: Vitamin A: from 18452±135IU / kg to 17301±106IU / kg, with a loss rate of about 6.2%. Niacin: from 112.0±4.6mg / kg to 102.2±2.9mg / kg, with a loss rate of about 8.7%. Vitamin B1, B2, B6: small changes (P>0.05). Vitamin D: from 1689±15IU / kg to 545±16IU / kg, with a loss rate of about 67.8%, which is quite significant. Equipment sterilization has a greater impact on some vitamins (such as vitamin D), but the loss rate of other vitamins (such as vitamin A and niacin) is low, and the vitamins in feed can still be well retained overall.

[0037] Table 5 Effects of sterilization on amino acids in feed (g / kg, x±s)

[0038] According to the data in Table 5, sterilization has little effect on the amino acids in feed, and the loss rate of some amino acids is low: lysine: from 10.20±0.12g / kg to 7.25±0.32g / kg, the loss rate is about 28.9%. Arginine, histidine, threonine, glutamic acid, serine, isoleucine: the changes were not significant (P>0.05). Leucine: from 14.2±0.1g / kg to 12.56±0.23g / kg, the loss rate is about 11.5%. Equipment sterilization has little effect on the amino acid content in feed. Except for lysine, the loss rate of other amino acids is less than 15%, indicating that the equipment can better retain the amino acids in feed.

[0039] in conclusion Sterilization effect: After the equipment is sterilized, the content of harmful microorganisms in the feed (such as total colony count, coliform group, mold and yeast) is significantly reduced, which fully meets the national standards and ensures the hygiene and safety of the feed.

[0040] Nutrient retention: Equipment sterilization has little effect on the conventional nutrients (such as crude protein, crude fat), minerals and amino acids of feed, and the loss rate is generally less than 10%, indicating that the equipment can effectively retain the main nutrients of feed during the sterilization process.

[0041] Vitamin loss: Although the loss rate of some vitamins (such as vitamin D) is high, the loss rate of other vitamins (such as vitamin A and niacin) is low, and overall the vitamins in the feed can still be well retained.

[0042] This equipment can effectively kill harmful microorganisms while better retaining the nutritional components of feed. It has high practicality and promotion value and is recommended to be widely used in the feed processing industry.

The outer parts of the two secondary shafts 704 are connected with spiral stirring members 708 by bolts; the outer parts of the two secondary shafts 704 are connected with gears 711 by bolts, and the gears 711 are located above the transmission rod 703; the inner wall of the cylinder 1 is connected with an inner gear ring 707 by bolts, and the two gears 711 are meshed with the inner gear ring 707, and the outer parts of the two secondary shafts 704 are connected with cams 712 by bolts, and the cams 712 are located on the upper side of the gears 711, and the upper side of the cams 712 is connected with short shafts by bolts; the outer parts of the two short shafts are rotatably connected through bearings There are connecting rods 713, and the ends of the two connecting rods 713 away from the cam 712 are each provided with a narrow opening, and the inner walls of the narrow openings are rotatably connected to the outside of the movable rod 706 on the same side through bearings, and a groove 714 is opened on the inner wall of one side of the two rectangular grooves 709; racks 715 are connected to the inside of the two grooves 714 by bolts, and the racks 715 are located below the slider 710, and the outsides of the two movable rods 706 are connected to external toothed rings 716 by bolts, and the external toothed rings 716 located on the same side are meshed with the racks 715 on the same side.

[0045] Specifically, after the material is added into the barrel 1, the irradiator 6 is used to irradiate the barrel 1, and the driving motor 702 is started. The driving motor 702 drives the main shaft 701 to rotate, so that the gear 711 on the transmission rod 703 meshes with the inner gear ring 707 and rotates, so that the secondary shaft 704 drives the stirring rod 705 to stir the feed in the barrel 1 during rotation. As the secondary shaft 704 rotates, the cam 712 rotates with the secondary shaft 704 as the axis, driving the connecting rod 713 to push the slider 710 connected to the movable rod 706 to move back and forth in the rectangular groove 709. Since the outer gear ring 716 on the movable rod 706 meshes with the rack 715, the movable rod 706 can move back and forth in the rectangular groove 709 while driving the spiral stirring member 708 to rotate, so that the spiral stirring member 708 stirs the feed mixture with the transmission rod 703, and uses the rotation effect to stir the feed at the bottom of the barrel 1 to the upper part of the barrel 1.

Under the temperature measurement of the temperature sensor 9, the temperature in the cylinder 1 is controlled to be between 68 and 70 degrees Celsius and maintained for 30 minutes.

[0049] In a specific application scenario, the temperature control and heat exchange module 8 is mainly suitable for the temperature control and heat exchange link in the temperature control and heat exchange process, that is, the temperature control and heat exchange module 8 uses the heating tube 806 and the serpentine tube 803 to form two mutually isolated heat exchange systems in the device, so that the device can increase and decrease the temperature in the cylinder 1 in a shorter time, thereby strictly controlling the temperature maintenance time within the time required by the pasteurization method, thereby improving the sterilization effect of the device on the cylinder 1.

After a certain period of irradiation, the irradiator 6 is turned off, and the temperature control and heat exchange module 8 is used to increase the temperature in the cylinder 1 to 68 to 70 degrees Celsius and maintain it for 30 minutes (after irradiation by the irradiator 6, the heating pipe 806 is started, and the heating pipe 806 starts to heat the heat transfer oil in the heat exchange box 805, and the heating pipe 806 is started.
