Transport systems

In this 1-day course, the critical points of a conveyor belt are discussed, such as (in)direct product contact surface, accessibility, cabling, and frame construction.

OBJECTIVES:

1. Understanding the necessity of hygienic design (cleanability down to microbial level)

2. Assessment of (to be acquired) equipment for microbial cleanability

3. Designing, outsourcing, and supervising projects related to hygienic design
