I am afraid that this may seem disappointing, but it is not a good idea to use students to reduce the burden on the organizational unit. Probably, if your goal is to reduce workload, it is best not to take students. Read on to see why.
Although you did not indicate the level of knowledge related to the work that students possess and you did not mention the duration of their attachment, I believe from the tone of your question that their experience is not enough to get into the starting position. It is also reasonable to assume that they will not stay for more than 2-3 months.
Significant benefits that your organization can extract even in a limited time:
Pay attention and capture talented workers before they even enter the labor market. Later in their working life, they probably will not be so accessible.
Turn every student into your salesperson. Let them tell everyone how good your product is, conclude contracts in the future or make their colleagues envy their work experience, increasing the number of good candidates for your company.
Outsiders can help blind your processes, procedures, product, identify inefficiencies, etc.

Boost your morale: Maslow's theory of "need for respect." Even the youngest member of your team is getting a little older, as these students have yet to reach this position.
Reducing the workload means that you will need to find a set of tasks that is fairly independent, does not require knowledge or skills that students do not have, and it takes most of your team time to transfer. Tasks cannot be strategically important if they shake it, but cannot be operationally important. So you left with dusty requests for management reports or research and development.
Most likely, R&D is considered a more desirable job in your organization, and if you give only to students, then some people feel that they will suffer.
