Problems solved by technology

The moisture content of powder granulation should not exceed 15% (mass percentage), because the moisture content of the powder itself has reached about 12%, so the actual moisture absorbed by the powder in the conditioner does not exceed 3%. The tempering effect is not very ideal (such as insufficient temperature after powder conditioning, low gelatinization degree of starch contained in powder, poor stability of pellet feed in water, etc.), especially in the production of aquatic pellet feed

Embodiment Construction

[0020] as attached figure 1 As shown, a feed curing kettle is composed of a hollow main shaft 1, a communication pipe 3, a central steam inlet pipe 4 and a double-layer spiral blade 5 to form a combined screw conveying shaft A, which is supported on a bearing seat 7, and the central steam inlet pipe 4 and The hollow main shaft 1 is fixedly connected, and its two ends are movably connected with the rotary joint 8. The centerlines of the rotary joint 8 and the central steam inlet pipe 4 coincide with the centerlines of the two bearing seats 7. The fixed jacket of the rotary joint 8 is respectively connected with the steam inlet valve 17 , Drain valve 9 is fixedly connected. The inner chamber of the central steam inlet pipe 4 communicates with the inner chamber of the airtight double-layer helical blade 5 through the communication pipe 3 without steam leakage.

[0021] On the periphery of the combined screw conveying shaft A, there is an annular sleeve 2. The annular sleeve 2 an...

Abstract

The invention provides a feed curing kettle capable of conducting continuous heat preservation, heating, drying and conveying on feed to make starch in powder fully gelatinized. The feed curing kettle comprises a material barrel formed by an annular sleeve (2) and end plates (10). A combined screw conveying shaft (A) formed by a hollow main shaft (1), a center steam inlet pipe (4), communicating pipes (3) and a double-layer screw blade (5) is arranged in the material barrel; the annular sleeve (2) is arranged on the periphery of the combined screw conveying shaft (A); the hollow main shaft (1) can rotate freely around the center lines of bearing pedestals (7); the center steam inlet pipe (4) is movably connected with rotary joints (8) at the two ends; fixing outer sleeves of the rotary joints (8) are fixedly connected with a steam inlet valve (17) and a water drain valve (9) respectively; the double-layer screw blade (5) is fixedly connected to the outer circle of the hollow main shaft (1); the communicating pipes (3) are communicated with the center steam inlet pipe (4) and the double-layer screw blade (5); the hollow main shaft is connected with a driving mechanism.

Description

technical field [0001] The invention relates to feed curing equipment, which belongs to the field of feed machinery. Background technique [0002] In the production process of pellet feed in my country, the powder is usually subjected to conditioning treatment in the conditioner (spraying steam to heat and humidify to gelatinize starch) before pelleting, and then enters pelleting. The moisture content of powder granulation should not exceed 15% (mass percentage), because the moisture content of the powder itself has reached about 12%, so the actual moisture absorbed by the powder in the conditioner does not exceed 3%. The tempering effect is not very ideal (such as insufficient temperature after conditioning of powder, low gelatinization degree of starch contained in powder, poor stability of pellet feed in water, etc.), especially in the production of aquatic pellet feed. Contents of the invention [0003] The purpose of the present invention is to provide a feed curing ...
