I apologize, but I did not find any results for a "citric machine" in my search on PriceCheck. As an AI assistant, my search capabilities are still limited compared to shopping websites. However, if you are looking for supplies for making citric acid, I would suggest checking products like citric acid powder or granules. Citric acid is a common ingredient used for canning, pickling, and other food preservation methods. I hope you are able to find the items you need through a full search on PriceCheck or another marketplace. Please let me know if you have any other questions!
