Steam is an indispensable energy source in animal feed production. It is widely used in processes such as feed pretreatment, pelleting, sterilization, drying, and maintaining product quality. Selecting the right steam boiler not only improves the quality of feed pellets but also effectively reduces fuel consumption and production costs.

I. In which processes are boilers used in feed mills?

In animal feed production, steam is primarily used for conditioning, pelleting assistance, sterilization, heat treatment, and equipment cleaning. The main point of steam consumption is typically the conditioner located before the pellet mill, where saturated steam heats and moistens the feed powder before it is compressed.

II. What factors must be considered when selecting a boiler?

(1) Determine the required steam volume

Calculate the boiler capacity based on the feed mill’s hourly output, the proportion of pelletized feed, and the total steam consumption of the workshop’s equipment.

The boiler capacity must not only meet current production demands but also include an appropriate margin to accommodate future capacity expansion.

(2) Selecting the Appropriate Fuel

Fuel availability and local fuel prices are key factors in boiler selection.

Common fuels include: natural gas, diesel, biomass, and coal.

If local resources such as wood chips, rice husks, or other agricultural waste are abundant, a biomass steam boiler can be selected to reduce operating costs.

If the local natural gas supply is ample and there are high requirements for clean combustion and automated operation, a natural gas boiler is a good choice.

(3) Selecting the Appropriate Steam Pressure

Stable steam pressure ensures consistent conditioning temperatures, thereby improving pelletizing efficiency and pellet hardness. Professional boiler manufacturers can recommend suitable operating pressures for a project based on the customer’s production line parameters.

(4) Consider Boiler Efficiency and Automation Level

Modern feed mill boilers should typically feature: high thermal efficiency, automatic combustion control, automatic water level control, comprehensive safety protections, and ease of operation and maintenance. These features can help feed mills reduce fuel consumption and labor costs.

(5) Environmental Protection and Emissions Policies

Strict compliance with local environmental regulations requires prioritizing low-nitrogen gas boilers or standard-compliant biomass boilers.

Auxiliary Equipment: Consider whether environmental treatment equipment such as desulfurization, denitrification, or dust removal systems is required.
