AI Technical Summary

Technical Problem

Traditional Xiaochaihu granule production uses an intermittent process, resulting in low production efficiency, unstable product quality, and large batch-to-batch differences, making it difficult to meet the needs of high-efficiency production.

Method used

A continuous production method for Xiaochaihu granules is adopted, which optimizes the pretreatment steps of fillers and extracts by airflow premixing, closed pipeline transportation and online detection of extract viscosity, controls the moisture and viscosity of extracts, and rationally connects granulation and drying processes to achieve efficient connection of each process.

Benefits of technology

It improved production efficiency by about 130%, ensured the stability and consistency of product quality, achieved a one-time pellet forming rate of over 80%, and reduced material and energy consumption.

Abstract

This invention relates to an intelligent continuous production method for Xiaochaihu granules, comprising the following steps: sieving and pulverizing the filler, and conveying it to a preparation silo for airflow premixing; adding the extract to an extract tank and stirring until uniformly mixed; conveying the premixed filler and extract to a mixer, mixing uniformly, adding a wetting agent, and mixing to obtain a soft material; simultaneously premixing the filler for the next batch; conveying the soft material to a granulator for granulation, and feeding the granules into a fluidized bed hot air section for drying; conveying the filler for the next batch to the mixer; after the soft material is conveyed, sequentially conveying the extract and wetting agent to prepare the soft material for the next batch; after the granules are transferred to the fluidized bed cold air section, granulating the soft material for the next batch and feeding it into the fluidized bed hot air section; sieving to obtain the final product. This continuous production method improves production efficiency while also enhancing product quality and stability, and significantly saves materials and energy.
