Hopper with inclined screw conveyor

Ø400×4500 mm. hopper with an inclined screw conveyor. The solution is manufactured as a sanitary solution in accordance with EC-1935/2004 (the food directive)

What design features have been taken to manufacture a sanitary solution?

1. All material is manufactured in stainless steel 1.4301
2. All weldings have been made with 100% TIG-welding
3. The inclined screw conveyor have been designed with lids for easy cleaning
4. The Pack box in the bottom is easy accessible for demount during cleaning
5. Over the gear box there is a lid to protect the gear box for cleaning water
6. All surfaces has been designed as vertical as possible to drain cleaning water away

BEMA has authentication to manufacture applications in accordance with EC-1935/2004. We are controlled by the authorities every year. See a similar solution in accordance with EC-1935/2004

Advantages for a hopper with a screw conveyor for food material

1. It can be fully closed
2. It is cleanable – however you must do it manually to be fully sure it is cleaned
3. All material in contact with the food material can be made in stainless steel
4. You can combine material storage with material transport

When you use an inclined screw conveyor in combination with a hopper, it is difficult to ensure an accurate dosing. The inclined screw conveyor moves the material to a higher level. If you also need to dose the material, you shall combine a horizontal dosing screw with an inclined lifting screw conveyor.

FAQ – Hopper with Inclined Screw Conveyor

1. What is the purpose of a hopper with an inclined screw conveyor

This solution is designed to store and transport food‑grade materials while lifting them to a higher level in the process line. It combines material storage with efficient conveying, making it ideal for hygienic applications where controlled flow is required.

2. How the design ensures a sanitary and food‑approved solution

All components are manufactured in stainless steel 1.4301, and every weld is made using 100% TIG welding. Surfaces are designed vertically to drain cleaning water, lids allow easy access for cleaning, and the pack box is positioned for quick disassembly. The entire system complies with EC‑1935/2004 food‑contact regulations.

3. What advantages the hopper and screw conveyor offer for food materials

The system can be fully closed, all contact surfaces can be made in stainless steel, and the design supports manual but thorough cleaning. It provides both storage and transport in one unit, improving hygiene and reducing equipment footprint.

4. When an inclined screw conveyor is not suitable for dosing

Inclined screw conveyors are excellent for lifting material but not for accurate dosing. For precise feed control, a horizontal dosing screw should be combined with the inclined conveyor to ensure consistent and measurable output.
