Description

Technical Field

[0001] The invention belongs to the technical field of suckling pig feed processing and relates to suckling pig feed conditioning equipment and a working method thereof. Background Art

[0002] Feed is the material basis for the development of modern animal husbandry and aquaculture, an important part of the modern agricultural industry system, and plays an extremely important role in the national economy (Ding Qiang, Wang Zhengnan. The status and influence of the feed industry in the national economy [J]. Feed Research, 2010 (2): 13-14). my country's feed industry started late, but the demand is large and the development is fast. In 2016, the total feed output in China was about 210 million tons, and China has become the most important feed producer in the world (National Animal Husbandry Station. Statistical Profile of the National Feed Industry in 2016 [J]. China Feed, 2017 (13): 1-2).

[0003] Piglets are a key stage in the entire growth and development process of pigs, and piglet feed is the daily diet for piglets during their growth stage. The quality of piglet feed will directly affect the entire growth stage of pigs, thereby affecting the physique, survival rate and feeding cost of growing pigs, and further affecting the economic benefits of the entire farm. Conditioning is a key process in the processing of piglet feed, which can improve the quality of feed pelleting, reduce the powdering rate of pellets, and promote the digestion and absorption of protein and starch components in feed by animals (Yu Ruhua. The effect of conditioning technology on the quality of pellet feed [J]. Animal Husbandry, 2001 (3): 53-54); it can improve the gelatinization degree of feed starch and increase the cohesiveness of pellets, so that the stability of pellet feed, especially aquatic feed, in water is improved, reducing feed waste and water pollution. In addition, from the perspective of animal nutrition, conditioning can denature proteins, gelatinize starch, soften crude fiber, and increase moisture content, which is beneficial to the digestion and absorption of nutrients by animals. From the perspective of feed safety and hygiene, the hot and humid environment in the conditioning chamber can destroy fungi such as Salmonella, pathogenic bacteria, protease inhibitors and other harmful factors (Xue Zhicheng. Conditioning problems in feed processing technology [J]. Jiangxi Feed, 2007 (4): 25-26).

[0004] The conditioning equipment is the main equipment for feed conditioning operation. The existing single-cylinder conditioning equipment mainly includes a conditioning equipment housing and a conditioning rotor. The conditioning equipment rotor is located in the conditioning equipment housing. One end of the conditioning equipment housing is provided with a feed inlet and the other end is provided with a discharge port. The conveying section of the conditioning equipment rotor is distributed with paddles, which mainly play the role of pushing the material and stirring and mixing. During the feed conditioning process, the material to be conditioned enters the conditioning equipment housing from the feed inlet, and saturated steam is added to the conditioning equipment housing at the same time. Under the stirring and pushing of the conditioning equipment rotor, the material is mixed with the steam and pushed forward, and the conditioning is completed at the discharge port and enters the next process. The single-cylinder conditioning equipment has a small material processing capacity, a short conditioning time, insufficient contact between steam and material, a low conditioning temperature, a low degree of material maturation, and a poor conditioning effect. In order to improve the conditioning effect and obtain pellet feed with high forming rate, low powdering rate and good quality, it is generally necessary to configure 2 to 3 layers of conditioning equipment, which increases the structure and working space of the conditioning equipment and increases the production cost. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems existing in the prior art and provide a suckling pig feed conditioning equipment with high degree of maturation, high nutritional value, good molding quality and sanitation and safety.

[0006] The invention also provides a working method of the suckling pig feed conditioning equipment.

[0007] The technical solution of the present invention is as follows:

[0008] A suckling pig feed conditioning equipment, comprising a feed inlet, a first cavity, a second cavity, and a discharge port; the feed inlet is located at the upper part of the first cavity, and the feed inlet is communicated with the first cavity; a first motor is fixedly installed at the bottom of the first cavity, a first rotating shaft is fixedly installed on the output shaft of the first motor, and a first blade is connected to the first rotating shaft; a steam inlet is installed at the top of the first cavity, and the movement direction of the steam in the steam inlet is consistent with the forward direction of the material in the first cavity; a microwave device is installed on the side of the first cavity; the bottom of the first cavity is communicated with the bottom of the second cavity; a guide wheel is installed at the communicating part of the bottom of the first cavity and the bottom of the second cavity; a second motor is fixedly installed at the bottom of the second cavity, the second motor is connected to the second rotating shaft, and a second blade is installed on the second rotating shaft; the bottom of the second cavity is lower than the bottom of the first cavity, and an ultrasonic generating device is fixedly installed on the side of the second cavity; the second blade consists of a lower blade and an upper blade; the discharge port is located at the upper part of the second cavity.

[0009] Preferably, the lower blade is spiral-shaped and is concave inward; the upper blade is composed of a plurality of spiral lines, and there is a certain gap between adjacent spiral lines.

[0010] Preferably, the gap between adjacent spiral lines in the upper blade is 5-10 mm. Such a structural design can ensure work efficiency and improve the tempering and uniformity as much as possible.

[0011] Preferably, the bottom of the second cavity is 10-20 cm lower than the bottom of the first cavity.

[0012] Preferably, a plurality of water outlet holes are provided at the bottom of the first cavity.

[0013] Preferably, the guide wheel consists of a wheel body and a wheel axle; the wheel axle of the guide wheel is eccentrically arranged, and the wheel axle passes through the side wall of the first cavity to the outside of the tempering device.

[0014] Preferably, the lower end surface of the first cavity has a certain inclination angle with the horizontal plane, and the inclination angle is 20-30 degrees. Such a structural design is conducive to the discharge of condensed water and the entry of piglet feed from the first cavity into the second cavity.

[0015] The raw materials of suckling pig feed enter the first cavity through the feed inlet; the first motor drives the first rotating shaft and the first blade to rotate, so that the raw materials of suckling pig feed are uniformly and orderly transported from top to bottom. At this time, saturated steam also enters the first cavity through the steam inlet; the saturated steam and the raw materials undergo hydrothermal reaction in the first cavity, and are simultaneously heated, cooked and sterilized by the microwave heating of the microwave device. Then, the raw materials enter the second cavity through the bottom connecting channel between the first cavity and the second cavity, and the second motor in the second cavity drives the second rotating shaft and the second blade to rotate. The raw materials move from the bottom to the top of the second cavity, and the second stage of conditioning occurs with the upper steam during this period. When the raw materials move to the second upper blade, the conditioning has been basically completed. Since the well-conditioned raw materials have high degree of maturation, good gelatinization and high viscosity, they will enter the discharge port through the second upper blade and be discharged; the raw materials with poor conditioning effect have low degree of maturation, poor gelatinization and poor viscosity, and are difficult to agglomerate. Since there is a certain gap between the adjacent spiral lines of the upper blade, the raw materials will fall back to the bottom of the second cavity through this gap to continue conditioning until the conditioning is completed. The ultrasonic generator plays the role of maturing the raw materials of the suckling pig feed, and can also make the raw materials of the suckling pig feed after conditioning better uniformity.

[0016] The technical problem that the present invention also aims to solve is to provide a working method of a suckling pig feed conditioning equipment with high maturity, high nutritional value, good molding quality, and sanitation and safety.

[0017] A working method of a suckling pig feed conditioning device,

[0018] When the suckling pig feed conditioning equipment is working, the first stage conditioning is carried out in the first cavity, the microwave power is 22-24kW, the vacuum degree is 0.06-0.07MPa; the conditioning time is 5-10s; then it enters the second cavity for the second stage conditioning: the ultrasonic power is 3000-3300W, the frequency is 10-15kHz, and the conditioning time is 20-30s.

[0019] Preferably, when the suckling pig feed tempering equipment is working, the first stage tempering is carried out in the first cavity, the microwave power is 23kW, the vacuum degree is 0.06MPa; the tempering time is 8s; then it enters the second cavity for the second stage tempering: the ultrasonic power is 3250W, the frequency is 13kHz, and the tempering time is 27s.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the present invention in detail but not to limit the present invention.

[0030] Example 1

[0031] like Figure 1-5 , a suckling pig feed conditioning equipment comprises a feed inlet 1, a first cavity 2, a second cavity 3, and a discharge port 4;

[0032] The feed port 1 is located at the upper part of the first cavity 2, and the feed port 1 is communicated with the first cavity 2; a first motor 21 is fixedly installed at the bottom of the first cavity 2, a first rotating shaft 23 is fixedly installed on the output shaft of the first motor 21, and the first rotating shaft 23 is connected to a first blade 24;

[0033] A steam inlet 25 is installed at the top of the first cavity 2, and the movement direction of the steam in the steam inlet 25 is consistent with the forward direction of the material in the first cavity 2;

[0034] A microwave device 28 is installed on the side of the first cavity 2;

[0035] The bottom of the first cavity 2 is connected to the bottom of the second cavity 3;

[0036] A guide wheel 5 is installed at the connecting part between the bottom of the first cavity 2 and the bottom of the second cavity 3;

[0037] A second motor 31 is fixedly installed at the bottom of the second cavity 3, the second motor 31 is connected to a second rotating shaft 33, and a second blade 34 is installed on the second rotating shaft 33;

[0038] The bottom of the second cavity 3 is lower than the bottom of the first cavity 2, and an ultrasonic generator 35 is fixedly installed on the side of the second cavity 3;

[0039] The second blade 34 is composed of a lower blade 341 and an upper blade 342;

[0040] The discharge port 4 is located at the upper portion of the second cavity 3 .

[0041] In a preferred embodiment of the present invention, the lower blade 341 is spiral, and the lower blade 341 is concave inward; the upper blade 342 is composed of a plurality of spiral lines, and there is a certain gap between adjacent spiral lines. Such a structural design ensures the uniformity of tempering and the consistency of quality. Since the well-tempered raw materials have high maturity, good gelatinization and high viscosity, they will enter the discharge port through the second upper blade and be discharged; the raw materials with poor tempering effect have low maturity, poor gelatinization and poor viscosity, and are difficult to agglomerate. Since there is a certain gap between adjacent spiral lines of the second upper blade, the raw materials will fall back to the bottom of the second cavity through this gap to continue tempering until the tempering is completed.

[0044] In a preferred embodiment of the present invention, a plurality of water outlet holes are provided at the bottom of the first cavity 2. With this structural design, when the saturated steam reacts with the raw materials of the suckling pig feed in the first cavity 2 through the steam inlet 25, the saturated steam condenses and is discharged from the water outlet holes, thereby preventing excessive water from accumulating in the conditioning equipment.

[0045] In a preferred embodiment of the present invention, the guide wheel 5 is composed of a wheel body 51 and a wheel shaft 52; the wheel shaft 52 of the guide wheel 5 is eccentrically arranged, and the wheel shaft 52 passes through the side wall of the first cavity 2 to the outside of the quenching and tempering device. With this structural design, when the guide wheel 5 is blocked, the operator can adjust the gap between the wheel shaft 52 and the inside of the cavity by rotating the wheel shaft 52 outside the quenching and tempering device, thereby solving the blockage problem; it can also play a role in adjusting production efficiency.

[0046] In a preferred embodiment of the present invention, the lower end surface of the first cavity 2 has a certain inclination angle with the horizontal plane, and the inclination angle is 20-30 degrees.

[0050] Example 3

[0051] When the suckling pig feed conditioning equipment is working on the basis of Example 1, the first stage conditioning is carried out in the first cavity 2, the microwave power is 23kW, the vacuum degree is 0.06MPa, and the conditioning time is 8s; then it enters the second cavity 3 for the second stage conditioning: the ultrasonic power is 3250W, the frequency is 13kHz, and the conditioning time is 27s. The ripening degree of the suckling pig feed after conditioning is measured to be 36.8%, and the powdering rate after molding is 3.7%.

[0053] When the suckling pig feed conditioning equipment is working on the basis of Example 1, the first stage conditioning is carried out in the first cavity 2, the microwave power is 22kW, the vacuum degree is 0.07MPa, and the conditioning time is 10s; then it enters the second cavity 3 for the second stage conditioning: the ultrasonic power is 3300W, the frequency is 15kHz, and the conditioning time is 30s. The ripening degree of the suckling pig feed after conditioning is measured to be 31.5%, and the powdering rate after molding is 3.5%.

[0054] Example 5

[0055] When the suckling pig feed conditioning equipment is working on the basis of Example 1, the first stage conditioning is carried out in the first cavity 2, the microwave power is 24kW, the vacuum degree is 0.06MPa, and the conditioning time is 5s; then it enters the second cavity 3 for the second stage conditioning: the ultrasonic power is 3000W, the frequency is 10kHz, and the conditioning time is 20s. The ripening degree of the suckling pig feed after conditioning is measured to be 26.5%, and the powdering rate after molding is 8.1%.
