What throughput and evaporation capacity does the cooker need to handle?
Start with your raw-material flow. A continuous cooker is sized by its rated evaporation capacity — how much water it can remove per hour — not by a single headline tonnage figure.
Match rated evaporation capacity to your raw-material flow
- Estimate the water load entering the cooker from your raw material mix and upstream preparation.
- Compare the cooker's stated evaporation rate (kg/m²/hour) and total evaporation capacity (kg/hour) against that load.
- Leave headroom for variability in raw material moisture and feed rate.
Check whether capacity scales across the range you may need later
If you plan to expand, confirm the cooker platform scales across a documented range rather than only at one fixed size. For example, OrientalHK's Continuous Cooker is described with an evaporation rate over 35 kg/m²/hour and a scalable evaporation capacity of 1,300–14,000 kg/hour.
How is the cooker heated, and what steam conditions does it require?
Heating method and steam conditions determine both cooking performance and how the cooker fits your existing utility plant.
Steam pressure and heating method (direct vs. indirect)
- Confirm whether the cooker uses direct steam injection or indirect steam heating through a jacket or rotor.
- Record the maximum steam pressure the cooker is rated for and compare it with your boiler output.
- Check whether condensate handling and steam quality requirements are stated.
Compatibility with your existing boiler and steam supply
OrientalHK's Continuous Cooker is described as steam-heated with steam pressure up to 10 bar. Compare that figure with your available steam pressure before committing.
How does the cooker fit into the rest of the line?
A cooker is rarely a standalone unit. Its output must match downstream drying duty, and its vapor and odor streams must be handled.
Upstream crushing and material preparation
Check the feed size and consistency the cooker expects, and confirm your upstream equipment delivers it.
Downstream drying, and how cooker output matches dryer duty
Compare the cooker's discharge moisture and throughput with the dryer's rated duty. OrientalHK's Disc Dryer is described as continuous drying equipment using indirect steam heating at 6–10 bar steam pressure.
Odor and vapor control for cooker and dryer exhaust
Confirm how odorous gases from cookers and dryers will be treated. OrientalHK's Regenerative Thermal Oxidizer (RTO) is described as treating odorous gases from rendering cookers and dryers, destroying 98%+ of odor-causing compounds, VOCs and HAPs, and complying with EU environmental standards.
What materials, construction and discharge design should you verify?
Contact-part materials and corrosion/wear considerations
- Ask which contact parts are carbon steel, stainless steel or a hybrid construction.
- Check material selection against the corrosiveness and abrasiveness of your raw material.
Discharge and control options that affect labor and consistency
- Confirm discharge design and whether it supports continuous downstream flow.
- Ask what control and monitoring options are offered for feed rate, temperature and steam pressure.
What supplier documentation should you check before deciding?
Published specifications, source links and entity details
Request published specifications with source links, and confirm the legal entity behind the brand, its registered address and contact details.
Experience and scope of supply for complete rendering lines
Ask whether the supplier can supply cooker, dryer and odor-control equipment as an integrated line, and how long they have worked in the rendering industry.
