Problems solved by technology

In the prior art, the pressure of the puffing chamber is also adjusted by the speed of the screw, and the pressure is adjusted by setting a pressure ring before the discharge template, but these adjustment methods have their limitations, and the adjustment is made by changing the speed of the screw. It is necessary to change the transmission system, which will greatly increase the manufacturing cost; to set the pressure ring to adjust the pressure, it is necessary to disassemble the discharge device, which is time-consuming, laborious and inconvenient to operate

Embodiment 1

[0029] as attached figure 2 As shown, in December 2011, the propulsion screw of the extruder designed by the inventor was used in a workshop. The propulsion screw was divided into 4 sections, wherein the pitch L1 of the first section was 120 mm, and the number of spiral turns A1 was 5; The pitch L2 of the second stage is 95 mm, and the number of spiral turns A2 is 4; the pitch L3 of the third stage is 65 mm, and the number of spiral turns A3 is 4; the pitch L4 of the fourth stage is 40 mm, and the number of spiral turns A4 is 15 One, after 5 months of trial, the puffing effect is remarkable.

Embodiment 2

[0031] as attached image 3As shown, in December 2011, the propulsion screw of the extruder designed by the inventor was used in the third workshop. The propulsion screw is divided into 4 sections, wherein the pitch L1 of the first section is 110 mm, and the number of spiral turns A1 is 4; The pitch L2 of the second stage is 85 mm, and the number of spiral turns A2 is 2; the pitch L3 of the third stage is 55 mm, and the number of spiral turns A3 is 2; the pitch L4 of the fourth stage is 30 mm, and the number of spiral turns A4 is 10 One, tried for 5 months, the puffing effect is remarkable.

Embodiment 3

[0033] as attached Figure 4 As shown, in January 2012, the propulsion screw of the extruder designed by the inventor was used in the second workshop. The propulsion screw is divided into 4 sections, wherein the pitch L1 of the first section is 115 mm, and the number of spiral turns A1 is 4; The pitch L2 of the second stage is 90 mm, and the number of spiral turns A2 is 2; the pitch L3 of the third stage is 60 mm, and the number of spiral turns A3 is 2; the pitch L4 of the fourth stage is 36 mm, and the number of spiral turns A4 is 13 One, in the past 4 months of production, the puffing effect is remarkable, and the product has been praised by users.

Description

technical field [0001] The invention relates to a food and feed extruding machine, in particular to a propulsion screw of the extruding machine. Background technique [0002] With the development of the food industry and feed industry and the improvement of people's living standards, extruders have been widely used in the production of various high-grade food and high-grade livestock and poultry feed. Poultry digestion and absorption, easy storage and other significant advantages, especially for the raw material puffing processing with a starch content of 40%, it is generally required that the raw material after puffing processing is a high-mature product, by adding the high-mature raw material as the main formula component to food or feed , or directly use the highly matured raw material as food or feed, such food or feed is conducive to improving the final absorption rate of nutrients, and can improve the taste of eating, especially for young animals, whose physique is rel...
