Is it possible for a company to raise funds through an ICO even if it is not a startup?

For example: Say company X manufactures chocolates but now it wants to further expand its operations and needs funds for it, can it opt for ICO instead of a Private Equity fund or a Bank Debt?
Please help I am a complete newbie and this concept is confusing me a lot

Thanks
Yes, there are cases of successful fundraising via ICO for industrial projects (like zrcoin... And ours will join this list soon

) and, moreover, if the company is not a startup and has some history it will be
easier to raise because investors will feel more confident with existing business and proven business model and track records.
