Problems solved by technology

There are different requirements for the degree of feed expansion in aquatic feed. If the degree of expansion does not meet the requirements, some aquatic products will not be able to forage or some feed will be excessive, resulting in waste and deterioration of water quality. In the existing sinking material control system, generally Density control system or vacuum control system is adopted, and the investment cost of these two control systems is relatively high, and factors such as complex processing technology seriously affect its popularity
Existing extruder material control section and pressure distribution, such as Figure 4 As shown, the screw sleeve is equipped with a screw rod, the end of the screw rod is provided with a Venturi, and a template and a cutter device are provided outside the Venturi. The structure is complex, the pressure distribution is not stable, and the effect is poor when producing sinking materials. , and the internal pressure is not easy to control during the production process, which in turn affects the quality of the production materials

Embodiment 1

[0018] Example 1 : see figure 1 , figure 2 , image 3 , an extruder thrust sinking material control system, the control system includes a screw sleeve and a thrust screw 10 arranged inside the screw sleeve, a template 1 is provided at the discharge end of the screw sleeve, and a cutting device 3 is provided in front of the template , the gelatinized feed is cut into different sizes according to the needs by the cutting device, the splitter cone 2 is fixedly connected in the middle of the template, and the gelatinized feed enters the mold hole of the template under the diversion action of the splitter cone 2 , an extrusion forming area 9 is provided in the area where the distance from the template in the screw sleeve is L, and the extrusion forming area is arranged between the template 1 and the thrust screw 10, and the thrust screw 10 close to the extrusion forming area is fixed with pressure ring6. The overall structural design of this technical solution is ingenious, ...

Embodiment 2

[0019] Example 2 : see figure 1 , figure 2 , image 3 , as an improvement of the present invention, the distance L is 250-350mm, that is, the length of the extrusion forming zone is set to 250-350mm, and the extrusion forming zone of this length can ensure that the gelatinization degree of starch is ≥ 85%, The urease activity of soybeans is ≤0.2Ua, and the sinking rate of the formed material is ≥95%, meeting the requirements of the industry standard, and the rest of the structure and advantages are exactly the same as those in Example 1.

Embodiment 3

[0020] Example 3 : see figure 1 , figure 2 , image 3 , as an improvement of the present invention, the screw sleeve 11 is provided with a spacer 7, and the spacer 7 is provided with a water outlet 5 and a water inlet 8, which can be set according to the needs. The spacer is provided with circulating cooling water, which is convenient The temperature of the inner sleeve and the material drops, greatly reducing the secondary expansion and pressure of the material, so that the extrusion density of the material is greatly improved. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a thrust sinking material control system of a bulking machine. The thrust sinking material control system is characterized by comprising a threaded sleeve and a thrust screw arranged inside the threaded sleeve, wherein a template is arranged at the discharge end of the threaded sleeve, a cutting device is arranged in front of the template, a dividing cone is fixedly connected to the middle of the template, a squeezing forming region is formed within a region in the threaded sleeve and away from the template by a distance L and located between the template and the thrust screw, and a pressure ring is fixedly connected to the thrust screw close to the squeezing forming region. The thrust sinking material control system of the bulking machine is ingenious in overall design, compact in structure, relatively low in cost, simple in processing process, and convenient for large-scale popularization and application; besides, the control system is capable of effectively promoting the development of Chinese feed industry and greatly reducing the dependency on foreign imported equipment.

Description

technical field [0001] The invention relates to a control system, in particular to an extruder thrust sinking material control system, which belongs to the technical field of feed processing equipment. Background technique [0002] The puffing machine belongs to a kind of equipment for processing puffed food, such as processing rice, corn, soybean, wheat, etc. in daily life. Its main working principle is that mechanical energy is converted into heat energy, and the food is extruded and cooked with the heat generated when the machine is rotating. The most obvious feature of the puffed food is that the volume becomes larger; With the improvement of the level, the extruder has been widely used in the production of various high-grade food and high-grade feed. [0003] China is the largest aquatic product country in the world, and the aquaculture industry is increasing at an annual rate of about 10%. With the development of food industry and feed industry and the improvement of...
