Small-sized conditioner for testing

Abstract

The invention belongs to the technical field of food feed machinery, and relates to a small-sized conditioner for testing. The small-sized conditioner is formed by a conditioner shell and a conditioner rotor, wherein the conditioner rotor is arranged in the conditioner shell. In the invention, the diameter of a feed cavity is smaller than the diameter of a conditioning cavity, a feed section adopts a helical blade propelling mode, the adding for steam is carried out by adopting an axial multipoint adding mode, the steam can be added into materials in the conditioning cavity from steam adding holes which are annularly distributed on a steam adding flange after the steam enters into a steam cavity, the adding direction of the steam and the advancing direction of the materials are consistent, material seal is formed at the position of the steam adding holes, the backflow of the steam is prevented, and the materials can be preheated by the steam in the steam cavity. Compared with the conditioner in the prior art, more steam can be used for carrying out the transmission of heat and water with the materials, the consumption of the steam can be reduced, and the conditioning efficiency and the conditioning quality are increased; and the angle of a helical blade is adjustable, and thus parameter related to a conditioning technology of feed or food can be optimized. The small-sized conditioner disclosed by the invention is suitable to be used for a scientific test and research in feed or food industry.

Description

technical field [0001] The invention belongs to the technical field of food and feed machinery, and in particular relates to a small-scale test conditioner. Background technique [0002] The conditioner is the main equipment in the food and feed conditioning process. Its main function is to perform hydrothermal conditioning on the material before granulation, so that the material can fully absorb heat, water and liquid, and meet or approach the requirements of the granulation process. , and at the same time complete the material delivery from the feeder to the granulator. The main evaluation indicators of the conditioner are conditioning time, water and liquid absorption, starch gelatinization degree and the required additional power. [0003] Conditioners can be divided into long-time conditioners and short-time conditioners according to the conditioning time; according to the strength of steam, they can be divided into high-temperature conditioners, high-pressure and low-...

AI Technical Summary

Problems solved by technology

For small test conditioners, the inner diameter of the conditioning chamber is smaller, the distance between the steam addition port and the conditioner main shaft is closer, and the "cavitation" effect is stronger. It is easy to be corroded and failed, which seriously reduces the service life of the conditioner spindle, reduces the stability of the equipment and the reliability of the experiment

[0006] With the steam addition method in the conditioner of the prior art, during the feed processing process, the steam is easy to return to the connecting pipe between the feeder and the conditioner, blocking the feed inlet

In the conditioner with a small diameter of the conditioning cavity, the phenomenon of steam return will seriously affect the normal operation of the equipment

[0007] Therefore, the steam addition method perpendicular to the main axis of the conditioner is not suitable for small-scale conditioners for experiments, and it is in line with the scientific research and experiments of my country's feed or food industry to design a conditioner that is more suitable for small-scale experiments on feed or food. urgent
