Recently, a brewery in Kazakhstan successfully put into operation a waste brewer's yeast drying production line, marking a breakthrough in the resource utilization of waste in the local brewing industry. The production line, custom-designed by Zhengzhou Jiutian, includes an intelligent feeding system, a steam drum dryer, and automated packaging equipment, achieving a fully enclosed process from wet yeast to dry powder.
The core equipment utilizes low-temperature heat pump drying technology, preserving the active components of yeast through precise temperature control (60-80℃), reducing energy consumption by 40% compared to traditional processes. Its modular design supports rapid switching between different material drying modes and is equipped with a dust removal and purification system to ensure emissions meet standards.
The dried yeast powder has a protein content of 45% and is rich in B vitamins, making it a high-end animal feed additive with a market price five times higher than wet yeast. Through resource utilization, the company processes 6,000 tons of waste yeast annually, generating direct revenue exceeding 3 million yuan, while saving 1.5 million yuan per year in waste disposal costs, shortening the investment payback period to 12 months. This project provides a replicable circular economy model for the brewing industry in Central Asia.
