More feed. Less resources. Better quality.

ProSid™ Pellet Pro helps feed mills manage moisture more effectively, improving feed yield, mill efficiency and feed quality through patented ester technology.

The impact of moisture loss

During the pelleting process, 0,5-2,5% of the moisture in your raw materials can evaporate. This means:

lost saleable feed

higher energy costs

lower throughput

potential impacts on feed quality.

The power of esterification

ProSid™ Pellet Pro is built on Perstorp’s proprietary technology binding glycerol esters to propionic acid: a step change in
moisture management. It maximizes the benefits of added moisture while controlling the risks that come with it.

FAQ

Why does feed lose moisture before it ever reaches the animal?

Because raw materials do not hold the moisture they were bought with. Incoming materials are tested on arrival, but from that point equilibrium moisture content (EMC) governs what happens: in dry storage the material equilibrates downwards and moisture is driven off, and hammermilling drives off more. By the time the formulation is mixed, actual moisture is well below the figure recorded days earlier. The nutritionist is therefore formulating against numbers that are no longer true, and the shortfall — typically 0.5–2.5 % moisture — is unintentionally made up with other raw materials.

Is that loss material enough to worry about?

Moisture-related shrinkage between intake and finished feed runs at 0.5–2.5%, so a mill loses 5–25 kg of saleable product per tonne — 7.2 to 36 million tonnes of feed weight a year at global scale. Yet insufficient moisture makes feed harder to process: efficiency falls, energy per tonne rises, pellet quality suffers. Adding water back is common practice, but water alone distributes unevenly and is harder still to retain; particles resist wetting, so it sits on and between them, raising free water, water activity and microbial risk.

Why is low mash moisture a mill problem and not just a yield problem?

Dry mash is difficult to condition. Moisture is required for particle adhesion, and it drives starch gelatinization in the conditioner — which affects pellet binding and nutrient availability alike. Peer-reviewed work dating back to 2001 has shown improved animal performance where finished feed moisture was managed to appropriate levels. A dry mash therefore costs yield, pellet quality, throughput and energy at the same time.

Why can I not simply add water at the mixer?

Adding free water is the intuitive response and the wrong one, for three reasons:

Feed safety. Free water raises water activity (aW), the parameter that governs microbial and mold growth. A moisture gain becomes a feed safety liability.

It does not stay. Surface tension keeps water on the outside of the particle, where it is driven off again. Typically, 50–60 % of added free water is never retained in the finished feed.

It relocates. What does not evaporate condenses in the milling equipment, creating build-up and a mold reservoir inside the process itself.

What about the surfactant plus ammonium propionate products already on the market?

Those represent the previous generation of moisture products. They combine a surfactant — usually polyethylene glycol ricinolate — with ammonium propionate. The surfactant reduces surface tension, but reducing surface tension is not the same as driving absorption: the water is made wetter, not held. Ammonium propionate is volatile, so propionic acid recovery in the finished feed is reduced.

What exactly is ProSid™ Pellet Pro?

A formulated pellet conditioning product built on Perstorp’s patented glycerol esters of propionic acid, combined with propylene glycol ricinoleate and further organic acids. It is applied as a water solution through liquid dosing equipment and delivers a managed moisture program and mold control in a single application.
