Global breweries generate tens of thousands of tons of waste every day, including yeast residue rich in high protein and amino acids, as well as bioactive substances. In the context of high prices of traditional protein sources (fish meal, soybean) in the market, they can be used as a good substitute for protein feed for poultry farming, aquatic feed, ruminant animal feeding, etc., reducing breeding costs.

The core position of drying technology

The moisture content of beer waste yeast is usually higher than 85% and cannot be directly used as feed. In the process of converting wet yeast into high-value feed, drying equipment is the key to determining the quality of the final product. Beer yeast belongs to non pathogenic fungi and has no biological safety risks after drying treatment. Traditional direct drying can easily damage the active ingredients in yeast cell walls, while modern indirect heating drying technology can effectively protect the biological activity of yeast and achieve large-scale industrial production. The Jiutian brewer's yeast dryer uses saturated steam on the inner wall of a stainless steel drum to indirectly heat the material, forming a very thin film on the outer wall of the drum. After one rotation of the drying drum, the material can be completely dried. The sheet-like material automatically falls into the discharge port under the action of the scraper device, achieving thorough unloading. The operation is simple, the drying efficiency is high, and the moisture content of the dry material is uniform. Compared with the spray dryer, the drum dryer is used to dry beer yeast liquid, with less equipment investment and more stable operation.

Application of dry yeast feed

1. Poultry farming

Improve intestinal health and increase feed conversion rate (FCR). Research has shown that its extract can reduce pathogen infections and enhance disease resistance.

2. Aquatic feed

As a high-quality substitute for fish meal. Partial substitution of fish meal can maintain growth performance during the juvenile stage of marine fish, such as sea bass.

3. Milk and rumination

Relieve the risk of gastric acidosis and improve the milk production performance of cows. Yeast cell walls help stabilize the microbial balance in the digestive system.

Although beer yeast is waste, it can be used as high protein animal feed after drying treatment. Zhengzhou Jiutian provides a complete set of beer waste feed utilization solutions. If you are interested, please feel free to contact us.
