Process screw conveyor for pre-cooking

Process screw conveyor for pre-cooking of beans and soup meat. BEMA has designed this process screw conveyor in close cooperation with the customer.

Key elements in the design of the process screw conveyor

• The screw flight was a challenge due to the large diameter and the holes placed inside the screw flight
• The holes are made in the screw flight to ensure the liqued to flow freely during the process
• The size of the holes are relatively large to avoid blocking of the beans
• The retention time is approximately one hour
• The screw trough is supplied with inlets and outlets for hot water
• The screw conveyor deliver to a closed container in the end where a band takes the material to the next process step
• The soup is drained out in the bottom

Rising cover system

• The top of the process screw conveyor is supplied with linear acutuators for automatic control of the opening
• The system is designed to spare the manufacturing for heavy lift of lids

Designed for the food industry

• The process screw conveyor is designed in accordance with EC-1935/2004 – the food directive
• All surfaces in contact with the food material are manufactured in 2B plates
• All outer surfaces designed to for easy drainage of water during cleaning

In BEMA we have our own engineers and technicians that can assist during the design and manufacturing of process screw conveyor. We have many years of experience in designing screw conveyors that both transport and solve a process. This combination require skilled engineers, and you must expect design time for these types of applications. See another example of a BEMA process screw conveyor here

FAQ: Process Screw Conveyor for Pre‑Cooking

1. What is a process screw conveyor for pre‑cooking used for?

A process screw conveyor for pre‑cooking is designed to heat‑treat products such as beans or soup meat before they move to the next production stage. It ensures controlled retention time and uniform exposure to hot water during processing .

2. How does the screw design support the cooking process?

The screw flight includes large holes that allow liquid to flow freely through the material. This prevents blockage, ensures even heat distribution, and supports consistent pre‑cooking results, even with products like beans that can easily clog smaller openings .

3. What is the typical retention time in the conveyor?

The system is designed for a retention time of approximately one hour, allowing the product to be thoroughly pre‑cooked before discharge into the next processing step .

4. How is hot water integrated into the system?

The screw trough is equipped with dedicated inlets and outlets for hot water, ensuring continuous circulation and stable temperature control throughout the cooking process .

5. Does the conveyor include features for easier operation?

Yes. The top cover is equipped with linear actuators that automate opening and closing, reducing manual lifting and improving operator safety and ergonomics .

6. Is the design suitable for food‑industry requirements?

Absolutely. All food‑contact surfaces are made from 2B stainless steel plates, and the entire system is designed according to EC‑1935/2004 food‑contact regulations, ensuring full compliance with hygiene and safety standards.
