Recently, Zhengzhou Huarui Machinery Equipment Co., Ltd. (ZZCHRYSO) received a piece of good news – an Iranian customer made a special trip to our factory and personally witnessed the trial run of the straw briquetting machine they had purchased, before the equipment was shipped out. The machine ran stably and delivered excellent briquetting results, earning high praise and full recognition from the customer. The success of this trial not only proves ZZCHRYSO’s technical strength in the biomass energy equipment sector on the international market, but also provides a solid guarantee for the Iranian customer to convert agricultural waste into clean energy.

The straw briquetting machine is a piece of equipment specially designed to compress crop straws (such as rice straw, corn straw, wheat straw, etc.) into dense briquettes. After crushing and high‑pressure compression, the briquettes have significantly higher density, making them easy to store and transport, and they can directly replace coal for use in power plants, industrial boilers, and heating systems. ZZCHRYSO’s straw briquetting machine adopts a flat‑ring die structure, using rotational centrifugal force to evenly distribute material across each molding die, which effectively avoids machine jamming caused by local material accumulation and greatly reduces energy consumption per unit. The equipment is specially designed for biomass raw materials with high lignin content and difficult forming. Its multi‑channel sealing design effectively prevents dust from entering bearing lubrication areas, and the unique interaction of extrusion, friction, and shearing forces between the die and the roller ensures smooth discharge and higher production efficiency while maintaining a high compaction rate.

This Iranian customer has long been active in the biomass energy field, and their region is rich in agricultural straw resources. According to research data, Iran produces over 200 million tons of agricultural residues (such as straw) annually, which could meet 10%‑15% of the country’s energy needs. How to efficiently convert these “wastes” into clean energy has always been a key issue for local governments and enterprises. After evaluating many suppliers, the customer finally chose ZZCHRYSO as their partner.

Previously, other Iranian customers had already visited ZZCHRYSO’s factory for on‑site inspections and discussions. During this trial run, our technical staff accompanied the customer throughout the entire process, from equipment installation and commissioning to raw material feeding and pressing, strictly controlling every step. At the trial site, the straw raw material went through crushing, conveying, and pressing to successfully produce high‑density, uniformly sized biomass fuel briquettes. The forming effect greatly satisfied the customer. The customer stated on the spot that they have full confidence in ZZCHRYSO’s equipment quality and professional technical services.

The success of this trial is another important achievement in ZZCHRYSO’s deep cultivation of the international market and service to global customers. As a manufacturer with 17 years of experience in woodworking machinery and biomass equipment, ZZCHRYSO is always committed to providing customers with high‑quality, cost‑effective one‑stop solutions. In the future, ZZCHRYSO will continue to be driven by technological innovation and guided by customer needs, helping more customers in more countries and regions to realize the resource utilization of agricultural waste and jointly promote the development of the global green energy industry.
