Pig mane high pressure high temperature vacuum straightening and drying method

Abstract

The high pressure, high temperature and vacuum bristle straightening and drying process includes water soaking, high temperature and high pressure straightening, vacuum drying and other steps. It features that the vacuum pump is used to make negative pressure state inside the container, so as to make water inside the connector and in bristle gasified and exhausted to atmosphere. The technological process is simple, convenient, low in water, power and gas consumption, short, high in product quality and environment friendly.

Description

Technical field: [0001] The invention is a method for straightening and drying pig bristles in high-pressure, high-temperature vacuum, which is composed of high-pressure, high-temperature, straightening, vacuum, drying and other processes of pig bristles. Production of high-quality brush bristles of various types. Background technique: [0002] The pig bristles currently used as raw materials in the brush industry must be straightened before they can be used. The modern traditional process is: 1. Boil in normal pressure boiling water until the straightening is qualified → enter the drying room and dry until the next process. The production requirements are 2. High pressure and high temperature water boiling and straightening → drying in the drying room until the production requirements of the next process shall prevail. The process method is expensive, time-consuming, and has a long production cycle; it consumes more water, electricity, coal, and steam, and the product qual...
